  1. Among the top three Japanese car companies, only Toyota did not intentionally rush towards the end of the year. This will leave more foreshadows for the upstream in 2019. According to Daily Automobile, Toyota's retail sales in China in December 2018 were 123,300, up 14.7% from 107,500 in December 2017. Toyota's retail sales in China totaled 1,474,500 units in 2018, compared with 1,290,000 units in 2017, an increase of 14.3% last year, which is the sixth consecutive year that Toyota's sales in China have increased year-on-year. Compared with Nissan and Honda, the other two giants in Japanese auto companies, Toyota showed a double connotation last month: not only were it less than 176,191 Nissan cars in absolute terms of sales, but it was far from 191,907 Honda cars. In terms of year-on-year growth, Nissan fell 4.4%, Honda surged 33.8%, and Toyota's 14.7% was in the middle.

  2. At the Consumer Electronic Show 2019 (CES) in Las Vegas, BMW and Chinese tech giant Alibaba announced that the Tmall Genie (a smart speaker of Alibaba Group) intelligent voice assistant will be integrated into such BMW's models as the 3 Series and 5 Series. Production models carrying the Alibaba's technology is set to hit the market in October 2019. The latest cooperation allows BMW car owners who have the Tmall Genie-compatible facility at home to operate vehicle functions conveniently. For instance, using the Alibaba-developed voice assistant, users can turn on the in-car air conditioner and call up appointment stored in the BMW Connected mobility agenda and the navigation planning to their destinations just sitting at home. Besides, the voice-driven device can calculate and present mileage, battery life and fuel consumption for users. In addition, Tmall Genie's “AI plus Vehicle” solution will be integrated into the AliOS-based Banma in-car operating system and access to AutoNavi's A+Box intelligent mobility solution—both of them are backed by Alibaba Group—working in more flexible cooperative modes. Meanwhile, smart home developers and manufacturers will be benefitted from this voice AI technology by agreeing the open communication protocol issued by Alibaba AI Labs.

  3. According to foreign media reports, the German car companies represented by BMW, Daimler and Volkswagen have been working hard to develop electric vehicles and self driving cars, but the pressure is still relatively large. In North America, China and Europe, the world's largest automobile market, all automobile manufacturers have joined a new wave of competition. However, the German automobile industry has obvious disadvantages. Automobile electronics is the trend of the times, and digitalization is also the future direction of automobile development, including automatic driving. This means that in addition to the traditional automobile manufacturers, technology companies will continue to enter the competition in the future automobile market. From another point of view, for German auto companies, the opening of the era of electric vehicles is also more difficult. First, from the profit point of view, the profit of electric vehicles in the early stage of development is obviously less than that of traditional energy vehicles. For example, Toyota and Volkswagen, the traditional car giants, have annual operating profits ranging from 15 billion to 20 billion euros, while high-tech companies such as Apple make about three times their annual profits. Pressure bears the power, because Feilong Jiangli's parent company, Xipu, is supporting German brands such as Volkswagen and Daimler, we are full of expectations and confidence for the development of German brand automobile enterprises.
  4. Recently, BYD officially released the news that "Yuan EV535 is coming". According to the information on the poster, the maximum range of Yuan EV535 is 535 kilometers. According to the previous declaration information from the Ministry of Industry and Information Technology, BYD EV535's comprehensive operating conditions lasted 410 kilometers. In terms of appearance, there is no big difference between the cash of the new car. It is known that the interior of the new car will adopt the latest interior design of the BYD family and change into a large rotating screen. In terms of size, the length, width and height are 4360/1785/1680 mm and the wheelbase is 2535 mm, respectively. The new car is equipped with a permanent magnet synchronous motor with a maximum power of 120 kW and a maximum torque of 280 Nm. Power batteries are lithium-ion batteries, which can be upgraded to 410 km under comprehensive operating conditions. Feilong Jiangli is a supply of BYD car makers for traditional car models, and we strive to seek an opportunity to develop new energy parts.
  5. According to foreign media reports, Tesla announced in a regulatory document released on January 2, local time that the price of all car models in the United States had been reduced by $2,000. Tesla said the price cut would help compensate for the phasing out of electric vehicle subsidies by the federal government. Starting from January 1, Tesla Electric Vehicle Subsidies will be halved to $3,750 from the previous $7,500. After the price reduction, Tesla Model 3 started at $44,000 in the United States, Model S started at $76,000, and Model X started at $82,000, excluding tax subsidies provided by federal and state governments. In the United States, consumers of electric vehicles can receive subsidies of $2,500 to $7,500 from the government depending on the type of car they buy and the power of their batteries. In the two quarters after the total sales of 200,000 electric vehicles, subsidies will begin to decrease, while Tesla's cumulative sales of electric vehicles will exceed 200,000 in 2018. It is reported that Tesla consumers who pick up cars from January 1 to June 30 this year will receive a subsidy of $3,750, while those who pick up cars from July 1 to December 31 will only receive a subsidy of $1,875. After 2020, consumers who buy Tesla vehicles will not receive federal subsidies. As a auto parts supplier, Chongqing Feilong Jiangli will keep up-to-date information on new information and new energy industries.
  6. Seeking Opportunities in Cooperation Suzuki and Toyota Deepen Business Alliance in India According to LiveMint, Suzuki Motor Corp., parent company of Toyota Motor Co. and Maruti Suzuki India Ltd., is deepening business cooperation in all areas except equity alliances and competing in the changing car market. Since Suzuki and Toyota first announced their cooperation in the fields of green energy, security, information technology and mutual supply of products and components, the negotiations between the two sides have lasted for two years. Suzuki's Indian subsidiary, Maluti Suzuki, is the largest local automaker, while Toyota Kirloskar Motor Pvt. Ltd. ranks sixth in India. Further cooperation between Toyota and Suzuki may help Maluti consolidate its position as a leading automaker in India. Toyota has noticed that Suzuki's production process is simpler and more efficient than the company's inherent "Toyota Way", especially in a cost-sensitive market like India, where the "Toyota Way" is more organized, but more complex and time-consuming because it is based on the "Kaizen concept".
  7. According to foreign media reports, in the past three months, the inventory of Jeep Wrangler, unsold or already on the way by U.S. dealers, has exceeded 100 days'demand. Among them, there were 156 days in early November and 135 days in early December. The total U.S. inventory of the vehicle has risen from 69,579 in October to 85,979 in early December. With the introduction of both new and old products by Fiat Chrysler (FCA), Jeep Herdsman's stock in the first two months of this year has also exceeded 100 days, while dealers now have almost twice or even triple the stock of the previous JK version of the Herdsman. But distributors say another reason for the larger impact of inventory on sales may be price, which seems to be "more troublesome". A dealer in the Midwest of the United States said, "Our stock of horsemen has reached its highest level in history. Over the past three years, the price of horse herders has risen by $12,000, and now it has reached $55,000. Vehicles are price-sensitive products, and I think the price is a little too high, a little radical.
  8. 3. Improving self-driving requires reconsidering user experience OEM and Tier Ones have to rethink how humans understand and interact with autopilot technology, thus requiring the redevelopment of the entire dashboard. To ensure that drivers are 100% aware of what is happening, the limitations of the system and what they need to do if they need to drive, it is not enough to add a simple icon. Jason Johnson, Director of User Experience Design of Haman, points out that there are several problems to be solved in redesigning the vehicle dashboard. Does it involve tactile feedback? Is there an audio signal? Are warnings displayed on the head-up display? This year, the user experience of self-driving and semi-self-driving will begin to take shape. 4. The present and future automobiles need a sixth sense, or even a seventh sense. Tim Van Goethem, Vice President of HARMAN X Advanced Mobile Travel Solutions, predicts that the handover between vehicles (especially Level 2 and 3 self-driving) and humans requires a set of sensor technologies to create a comprehensive environmental view. In the future, there will be a trend to use multiple sensors at the same time, but designers will face challenges and need to integrate multiple sensors in a beautiful, safe and efficient way. New features such as augmented reality and synchronization across cloud platforms will increasingly be used to create a coherent and safe driving experience.
  9. According to the NDRC, Dongfeng Nissan will build a new energy vehicle power battery project to form an annual capacity of 600,000 e-POWER batteries. E-POWER is a new energy technology unique to Nissan, which uses on-board gasoline engine to generate electricity, but uses pure electric drive. Nissan calls the e-POWER powered vehicle "pure electric vehicle", but this type of vehicle can only refuel, can not be charged outside. After entering China, the technology is expected to be applied in Dongfeng Nissan's entry-level vehicles in advance. Nissan e-POWER power system features that wheels are powered directly by motors. In traditional hybrid power systems, when the battery power is low (or in the process of high-speed driving), low-power motors need to work with the engine to provide power for the wheels. In Nissan e-POWER power system, the engine is no longer connected to the wheel, it only plays the role of battery charging. At the same time, unlike pure electric vehicles, the energy source in the e-POWER power system is the engine, not the battery. Chongqing Feilong Jiangli strive to develop electronic water pumps,TMM variable oil pump. And we have supply 60W,120W electronic water pumps for car plant. maybe we’ll have an opportunity to cooperate with each other.
  10. Great Wall will put into operation SUV and electric vehicle with 100,000 additional capacity in Zhejiang The online car market has learned from the Development and Reform Commission that Great Wall Automobile will invest 2 billion yuan to build 100,000 new vehicles per year in Pinghu, Zhejiang Province, and plan to produce 50,000 new energy passenger cars, 30,000 SUV models and 20,000 pickups per year. This factory is the seventh complete vehicle factory in China after Baoding, Tianjin, Xushui, Chongqing, Rizhao and Zhangjiagang. Judging from the current production capacity distribution, Pinghu factory will mainly put into production Eurasia, Harvard F series and other models. Great Wall Automobile has a series of products such as Harvard H-series, F-series, WEY, Euler, Fengjun pickup truck, beam and so on, with an existing capacity of 105,000 vehicles. F series, WEY and Euler have just entered the market. With the improvement of product camp and the improvement of market demand, their capacity demand will be further expanded. Euler, as the "front position" of the Great Wall's new energy sector, is currently in the climbing stage. The first model iQ delivered 1,043 new cars last month, an increase of 46.9% over the previous month. The second model R1 has also been pre-sold, and the first limited number of 777 vehicles have been sold out. Sales of Harvard F series have broken 10,000 yuan a month. Sales of Harvard F5, the first model, have continued to climb, reaching 7,065 in November, a 12.77% annualized increase. Another flagship product, Harvard F7, has broken 10,000 terminal orders and sold 6,067 vehicles.
  11. Chang'an automobile sales fell 20.4% in November, and SUV models declined severely. As a supplier who has been cooperating with Chang'an, Chang'an's sales also affect the sales performance of Feilong Jiangli in Chongqing. We look forward to the recovery of Chang'an's sales, and promise to develop high-quality new products with Chang'an to provide better service to customers. Chang'an Automobile released the latest sales data: in November, Chang'an Automobile sold 118,902 Chinese brand cars, down 20.4% from last year. Among them, three SUVs, CS35 series, CS55 and CS75 have declined seriously. Chang'an CS75 sold 12,036 vehicles in November this year, down 54.5% from November last year. From January to November this year, it sold 132,680 vehicles, down 39.2% from last year. At present, the preferential range of Chang'an CS75 is also very large. The preferential price of bare-car has changed from 0.6 million yuan to 15,000 yuan, and it enjoys 24-period interest-free loan policy. Chang'an just launched a new model CS35 PLUS at the end of October this year. Now it is sold together with the old classic CS35. In November this year, 12,751 CS35 series two models were sold. Compared with November last year, the total sales of the two models were not as good as last year's single classic CS35, a 27.4% decline. Chang'an CS55 has a relatively stable performance. It sold 15,777 vehicles in November this year, basically the same as last November, but fell by 7.2% compared with last month. Chang'an CS55 was replaced in August this year, but the results are not obvious. Sales this month are still lower than rivals Geely Boyue (19,575) and Harvard H6 (54,226).
  12. "Downsizing Wave" Frequently Occurs in Winter for Big Car Enterprises GM: Closing 7 factories and laying off 15,000 workers In the cold wave of the car market, GM adopted a strategy similar to Ford's, namely, closing factories and laying off employees. On November 26, General Motors said it would cut production of unsalable models and lay off North American employees as the car market shrank. According to foreign media reports, GM will lay off 15% of its employees by the end of next year, involving nearly 15,000 people, including 25% of its executives. At the same time, GM will close seven production bases around the world, involving three plants in Osawa, Ontario, Canada, Detroit, Ohio, and Warren. GM's plans to cut jobs and close factories have provoked outrage from President Trump and even threatened to cancel GM's subsidies for electric vehicles. However, in the biggest restructuring in the last decade, GM CEO Mary Bola has shown considerable reform determination. In fact, as the first female CEO in GM's history, Mary Bola has been trying to build a "fortress" financial structure for GM. From selling Opel out of the European market, to exiting South Africa, East Africa, India and South Korea market one after another, to investing in emerging areas such as self-driving and mobile travel, GM, led by Bora, has contracted its global business scope and rapidly moved towards emerging industries and forward-looking markets. Today, GM's financial performance in North America and China continues to be good, especially in the Chinese market, GM's investment returns continue to hit record highs. Even so, GM, which is increasingly sensitive to the market and has a sense of crisis, has not been pursuing the expansion of its size in the global market, but has put streamlining its business and reducing its costs first. Compared with Ford being forced to lay off employees and shut down its car business because of its financial crisis, GM's approach is more like an initiative before the crisis. With the coming storm, it may be beneficial to prepare for self-protection in response to the cruel market.
  13. Faced with the great change of technology and innovation application, GM "laid off" employees The automotive industry, which has a history of 100 years, is in a period of great changes in various technologies and innovative applications. Traditional automotive giants have begun to adopt different strategies to adapt to this change, such as Toyota restructuring senior management, while GM plans to tailor employees. In response to the wave of automotive change, GM has chosen large-scale layoffs. According to the plan, GM will close five factories and lay off 15,000 workers in 2019. Through these measures, GM hopes to save $6 billion by the end of 2020 in order to speed up the company's transformation and cope with the wave of electrification and automation. GM expects to double its investment in electric vehicles and automatic driving in the next two years. GM's layoffs have been welcomed by Wall Street, but apart from that, workers' associations and the government have been fiercely attacked. Terry Dittes, head of General Motors at the American Federation of Automobile Workers, said it was a ruthless decision to cut or close factories operating in the United States. The Canadian trade union said GM Canadian workers would fight GM. S. President Donald Trump has threatened to cancel all subsidies to General Motors in response to the company's closure of U.S. factories and job cuts.
  14. Chrysler (China) Automobile Sales Co., Ltd. filed a recall plan with the State Administration of Market Supervision and Administration in accordance with the requirements of the Regulations on the Management of Defective Automobile Product Recall and the Implementation Measures of the Regulations on the Management of Defective Automobile Product Recall. It decided to recall some Jeep New Herdsman models from November 20, 2018, totaling 35. The car. During the period from May 7, 2018 to May 10, 2018, a total of 35 new Jeep models were produced. Some of the front suspension thrust rod brackets within the scope of this recall may not be welded properly, resulting in the separation of the thrust rod bracket from the frame, resulting in the reduction of vehicle steering capacity, increasing the risk of collision, and there are potential safety hazards.

    Hydrogen induced wear

    Hydrogen induced wear: hydrogen is released during the friction due to mechanical and chemical action. Hydrogen diffuses into the deformed layer of metal surface, causing a large number of crack sources in the deformed layer. The generation and development of cracks make the surface material fall off, which is called hydrogen-induced wear. Oxygen may come from material itself or environmental medium, such as lubricating oil and water.
  16. The most important component of the water pump is the pump shell and the inner parts of bearing and the bearing. To improve the pump, the most important thing is to optimize and improve the two parts. The following is a detailed introduction to the improvement of the two parts. 1. to improve the pump shell. When disassembly the pump to inspect the failure, there are a large number of debris seriously affect the quality of the pump and work efficiency. In this case, we can reduce the two holes used for drainage on the pump shell to one, and remove the drain holes on the upper part of the transmitter. This can greatly reduce the small particles and sundries into the pump, thus greatly reducing the interference of sundries on the pump and the other bad. 2. to improve the bearing. In the case of the failure of the bearing, we are generally sealed, the lubricating oil used by the bearing, the ball of the bearing and the bearing itself. So we should have a solution to these parts 3. to improve gasket. The traditional design is to design the sealing test as a double mouth seal, so the advantage of the design is that two ports are all frictional with the bearing, the roughness of the bearing surface is more appropriate and the wear of the lip is relatively slow; but the disadvantage is that a large amount of dust can be directly entered into the middle of the mouth and bearing, so that the plate will be used for a period of time. The interference between the bearing and the bearing decreases, thus losing the original function of the seal. There are two ways to improve it: the first is the sealing week of the bearing with double, and the sealing area is lengthened properly and the thickness of the chip mouth is thickened accordingly. The method is to change the original double mouth into the three form of the seal and seal the seal. The advantage of this structure is that the outer lip and mouth have increased the seal design, which can resist many dust. However, this method also has shortcomings, the mouth and the reverse cap friction, the surface roughness of the surface of the cover is relatively poor, it is very easy to wear and tear seal test, resulting in sealing failure. 4. to improve the lubricating oil. The bearing of the automobile pump is a more special bearing unit. Its environment is mostly temperature, humidity and dust, and the temperature of the water usually reaches about one thousand degrees, so the lubricating oil of the bearing is required. From our analysis of the fault, the lubricating oil in the bearing of the fault appears discolourable, which means that the grease in the lubricating oil is not enough, so the lubricating oil manufacturer should be required to increase the fat content of the lubricating oil so as to ensure the better protection of the bearing. 5. to Improve the contact ball of the bearing. Balls in bearing are important parts to ensure normal operation of bearings, but there are more and more damage to rolling balls. When measuring the hardness of the ball, it is found that most of the balls do not meet the required hardness requirements, which makes the bearings greatly wear at high speed and finally breaks down completely. Therefore, we should strictly supervise the production quality of the manufacturers, guarantee the hardness of the ball and pass the quality, so that the fundamental problem of bearing damage can be effectively solved.
  17. 1. the method of checking the oil level with oil dipstick First of all, if the car is running, stop the car first and shut down the engine for 10 minutes or so. This will return all the oil to the oil pan. With dipstick, see the specific method of oil dipstick (1) pull out the oil dipstick. Be careful. If you want to check the oil quantity, it must be in the case of vehicle cooling. If you just drive back, or the engine is running, it will be useless to see this. (2) cleaning up oil stains. After pulling out the oil dipstick for the first time, wipe the dipstick blade with a clean paper and then insert it. The second time you pull out the oil dipstick to see the amount of oil on the scale (3). If the oil is between the upper limit and the lower limit, it means that the oil quantity is normal. The so-called upper and lower limits generally have scales, which can be clearly seen. 2, the method of checking the oil level without the oil dipstick The car without the oil dipstick is generally an electronic gauge. The cars of each brand show that the small sense of the same is generally added with the oil, the level of the oil will be shown as idle speed is running a little while. Thanks for the help of the Chongqing Feilong Jiangli Auto Parts’ Technical dept.
  18. Precautions for the installation of water pump (1) the real reason for the damage of the water pump should be clearly defined. Before the pump is replaced, it is necessary to determine whether the radiator fan, the thermostat and the antifreeze are problematic. (2) it is possible to have a water pump with similar shapes but only for different types of engines, so the new water pump should be compared with the old pump before the water pump is installed, or the part number of the pump and the model of the engine should be checked in order to confirm whether the selected water pump is suitable for the model. (3) When installing the water pump, it is necessary to wet the pump sealant ring with coolant first. If you need sealant, be careful not to apply too much sealant. Do not apply grease for ease of installation. This will corrode the sealing ring and cause leakage of coolant. (4) Do not use the method of percussion pump shaft forced installation of the water pump, should check the pump installation difficulties of the real reason. If the excessive scale in the cylinder water channel leads to the difficulty of pump installation, steel wire brush or fine sand paper should be selected according to the scale situation. When tightening the pump mounting bolts, it should be gradually tightened according to the prescribed torque according to the diagonal direction. Excessive tightening can easily break the bolt or cause damage to the gasket. (5) it should be emphasized that the belt must be adjusted strictly according to the adjustment specifications for the need to adjust the tightness of the transmission belt. If the pump is damaged in a short period of time after the replacement of the new transmission belt, the tightness of the belt should be checked after removing the cause of the pump itself, and it should be checked whether the belt will always work in the same plane.
  19. Number of suspension points The number of mounting points depends on the length, mass, use and installation of the power assembly. The mounting system can be mounted at 3, 4 and 5 points. Generally, three-point and four-point mounting systems are used in automobiles, because if the number of mounting points increases when the vibration is relatively large, when the body deformation, some mounting points will be dislocated, so that the engine or mounting bracket force is too large and cause damage to the three points, the advantages of the support is that no matter how bumpy and jumping the car, it can always ensure the support. The point is in a plane, which greatly improves the force condition of the body. The front and rear suspensions of the four-point mount are mainly used to prevent the torsion of the power assembly, and the torsional stiffness is larger than that of the three-point mount. Three point mounting system Left suspension: connect with gearbox, mainly power assembly limit and supporting function. The right suspension: connected with the engine, it can isolate the engine, such as vibration, inertia force and vibration. Rear suspension: It is connected with the gearbox, and has the functions of longitudinal limit, bearing torque, driving condition limit and so on. Four point mounting system It can overcome the large torsional reaction force, but the torsion stiffness is large, which is not conducive to the isolation of low frequency vibration. Left and right suspension: close to the torsional inertia axis, support the power train up and down, and have the function of vibration decoupling. Front and rear suspension: with the transmission, it has longitudinal limit, driving condition limit and torque endurance.

    Free Forging Method

    Free forging Definition of free forging Free forging is the use of impact force or pressure on the metal between the top and bottom of the anvil free form in all directions, without any restrictions to obtain the desired shape, size and certain mechanical properties of the forging method. Free forging equipment The equipment of free forging can be divided into two categories: forging hammer and hydraulic press. The hammer used in production is air hammer and steam air hammer. Hydraulic press is the only way to produce large forgings by using static pressure generated by liquid to deform the blank. Basic process of free forging Rough upsetting is a forging process which makes the cross section of billet larger and the height smaller. There are two kinds of upsetting: integral upsetting and partial upsetting. Drawing and drawing is the opposite of upsetting. It is a forging process to increase the length of the billet and reduce the cross section. The punching process of punching holes or blind holes on billets is called punching. The characteristics of free forging and the application of free forging depend on manual operation to control the shape and size of forgings. Therefore, the forgings have low precision, large machining allowance, high labor intensity and low productivity. Therefore, it is mainly used in single-piece and small-batch production with simple structure and shape of forgings.

    Engine knock

    Engine knock In a gasoline engine, when the mixture (fully mixed with air and fuel) enters the combustion chamber at the intake stroke, the piston compresses it at the compression stroke. When the spark plug ignites the high-pressure mixture, the pressure generated by the combustion is converted to the power of the engine. The right side of the high compression ratio setting, more prone to detonation, so the need to use high octane fuel to avoid detonation. It is precisely because the combustion of the engine is very complex, so the need for a fairly accurate design and control, a little control error or abnormal, will cause abnormal combustion, and "detonation" is a kind of abnormal combustion. Simply speaking, knock is abnormal pressure in combustion chamber caused by abnormal combustion. Causes of detonation Firstly, the mixture burns in the combustion chamber, and the flame is spread around by the ignition point in a "wave", so it takes a short time from ignition to the complete combustion of oil and gas. Second, although oil and gas need to be ignited by spark plugs, too high temperature, high pressure environment will also make oil and gas spontaneous combustion. Generally, detonation is caused by the fact that the flame has not completely diffused after the ignition of oil and gas in the combustion chamber, and the long-range unburned oil is spontaneously ignited because of high temperature or high pressure. The impact between the flame and the normal burning flame produces great pressure, which makes the engine produce abnormal knock.
  22. China's shortcuts in automobile manufacturing industry Over the past nine years, China has become the world's largest automobile market and producer, with annual production and sales exceeding 25 million vehicles. China's automotive industry has also been the world's largest automotive industry in just a few years, driven by the huge domestic demand of the Chinese market. But there is not a strong enough component system to support the development of China's automobile industry. In March this year, the 2017 Top 100 list of global auto parts suppliers was officially unveiled. Unsurprisingly, Germany's Bosch Group continued to rank first with more than $46 billion in revenue, while German gearbox supplier Zeiff rose to second. From the third to the tenth ranking of parts companies are Magna, electronics, mainland, Aixin, modern Mobius, Virginia, Lear. In this ranking, China's highest ranking of parts companies is Yanfeng automotive interior system, followed by CITIC Deka ranked 71. And the selected parts enterprises are mainly single components. Feilong Jiangli supply water pumps for car plants. In contrast, there is no comprehensive automobile parts supplier in China's automobile industry.
  23. Inspection rules for rubber parts for automobiles 1.rubber hardness Test method of indentation hardness based on GBT531.1-2008 rubber pocket hardness tester contents and requirements Instruments and equipment: Shahr hardness tester (type A, D) Environmental conditions: the laboratory temperature is 23 C + + 2 C, the relative humidity is 60%~70231 Test method: the specimen thickness is at least 6mm. If the thickness of the sample is less than 6 mm, it can be stacked with no more than 3 layers of smooth, parallel samples with each layer thickness not less than 2 mm. The specimen must have enough area to make the needle and specimen contact position at least 12mm from the edge. Place the specimen on a solid plane, hold the hardness tester, press the pin at least mm from the edge of the specimen, press the pin smoothly on the specimen, and read it within 3 seconds after the full contact of the pin with the specimen. Results: the hardness values were measured 5 times at different locations of 6mm, and the median was taken. Feilong Jiangli will update the more inspection rules for automobile rubber parts
  24. Rubber shock absorber for automobiles With the development of social economy, the automobile industry at home and abroad is facing a period of rapid change, which is characterized by further improving the service life of the automobile under the premise of ensuring driving safety, riding comfort, high speed and luxury. Damping products are used to control the vibration and noise of automobiles and to improve their handling stability. They are generally placed in the engine frame, rod holder, suspension shaft lining, center bearing bracket, bump limiter and torsional vibration absorber to improve the safety and comfort of automobiles. Damping products can be divided into four categories: bracket type, shaft lining type, buffer type and damping type. The main requirements of damping, heat resistance and fatigue resistance are good. Automobile shock absorber rubber products include engine bearings, suspension components, rubber springs, rubber air springs and impact rubber protective parts. In recent years, in order to improve the safety, comfort and maneuverability of automobiles, the variety and quantity of shock absorber rubber products for automobiles are increasing as the number of shock absorber rubber products on a car has reached 50-60 pieces.
  25. 5 rubber materials for shock absorption purposes NR.SBR.BR is a common citrus material: NBR for oil-resistant vulcanizates; CR for weather-resistant vulcanizates: IR for high damping vulcanizates; EPR for heat-resistant vulcanizates. NR has excellent elasticity, good resistance to fatigue and aromatics, low tart and creep, good cold resistance, electrical insulation and workability. Therefore, NR is widely used as shock absorber in order to meet the requirements of low temperature or weather resistance, and can be modified with BR or CR. The shock absorber made of NR, BR and metal salts containing organic acid containing one OH group with more than 4 carbon atoms has good durability. The compression permanent deformation at 70Cx22h and 40Cx148h is 17.0% and 11.7% respectively. EPDM has attracted much attention in recent years due to its excellent weather resistance, ozone aging resistance, electrical insulation, heat resistance and cold resistance. Recently, Mitsui Chemical Co. and Kwannukawa Rubber Co. developed a new type of heat-resistant and shock-absorbing rubber material by using high molecular weight EIM and low molecular weight EHIM, and obtained a Japanese patent. The test results show that the damping property of the rubber is the same as that of NR, but its heat resistance and low temperature softness are better than that of other rubber such as NR. "The rubber material made of EDM for shock absorbers on automotive parts has very good heat resistance. After 190C *5 aging, the material still has very good interlaminar adhesion. Silicone rubber R or halogenated IR can be used when high damping is required; U has excellent wear resistance, flexibility resistance and resistance to hydrocarbon fuels and most organic solvents, as well as high physical properties, good electrical insulation, adhesion and aging resistance. . U has also been widely used in shock absorption and sound insulation, such as Adachi, etc. The rubber sheet with good shock absorption and sound insulation is made by U. The effect is good when it is applied to floor, ceiling and bending plate. Feilong jiangli could supply best quality rubber parts for car body parts.
