  2. Structural form of engine suspension mount In the design of engine mount, the purpose of mount, such as the quality of support and limited displacement, must be fully considered, and the reasonable shape must be chosen. There are three basic types of mounting: compression, shearing and tilting (see figure below).(Thanks for the help and support of Chongqing Feilong Jiangli Auto Parts technical department) If the displacement of the power assembly is too large, the total power cost will be caused, or the intake and exhaust system, control mechanism, pipeline, wiring and other peripheral parts will be damaged. At the same time, the mounting cushion is easy to damage. For this reason, suspension stiffness must be limited from overhanging structure 1, plus larger displacement. For example, when a car is accelerating or turning, the inertia force generated by the power assembly may cause a greater displacement of the power assembly. In order to limit the displacement of power assembly, it is necessary to design rigid suspension, that is, large stiffness suspension cushion 2, nonlinear and variable stiffness suspension structure, in order to reduce the vibration caused by small exciting force and limit the large vibration displacement when large exciting force. For example, the engine output torque is small when the car stops idling, or when the car runs at a constant speed. At this time, the lower stiffness of the suspended cushion should be designed to effectively isolate vibration. But in the fast start, the reaction force of the driving torque is very large, which can make the power assembly produce greater vibration. In addition, when the vehicle is running on uneven road surface, with the large ups and downs of the whole vehicle, the dynamic assembly also produces great up and down inertia. At this time, the stiffness of the suspension cushion is increased, which can effectively limit the vibration and position of the power assembly. Shift
  3. 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 powertrain 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.
  4. According to the engineer's statement of Feilong Jiangli .Automobile water pump is the key component of the engine cooling system. One end of the pump bearing inputs torque through the pulley, which drives the other end of the blade to rotate. In order to meet the development requirements of high power and high efficiency of the engine, higher performance requirements for pump bearings are put forward. Fracture, corrosion, peeling and grease leakage are common failure modes of automobile water pump bearings. Fracture is the most harmful. Therefore, it is necessary to analyze the failure modes of fracture and formulate corresponding preventive measures. The chemical composition, hardness, metallographic structure and heat treatment process of the broken shaft were determined by inspection and analysis to meet the requirements of relevant technical specifications. However, the toughness of the bearing after quenching is insufficient, resulting in low flexural torsional fatigue strength. The load of the pulley is transmitted to the pump bearing through the flange, and the receding groove at the back of the flange has a notch effect at the tip, which is the stress concentration position and the crack source is easy to appear. Therefore, it is necessary to change the heat treatment process of the pump bearing and optimize the geometry of the pump shaft.
  5. Engine cooling water pump is the main part of the cooling system of automobile engine. Its function is to force the cooling fluid in the engine to circulate in the cooling system and reduce the influence of high temperature on the engine during the working process of the engine. Water seal is the core of the work of the pump. The movement of the water seal itself is very simple, just rotates with the shaft. . Water seal, pump body and bearing are super-hard matching mechanical seals. This kind of seals is composed of static rings and dynamic rings, which are perpendicular to the shaft, and the smooth and straight surface of each other, and do relative rotation. Coolant movement in the pump is very complex, different types of water seals, using different types of coolant, if the water package is equipped with problems, the engine coolant will appear seepage, then the pump bearing lubrication will be washed away, the entire pump function will be invalid. There are two main types of water seals: one is separated (rotating ring parts and static ring parts are respectively installed on the pump), the other is integrated (rotating ring parts and static ring parts are first installed together, and then installed on the pump), separated water seals are mainly used in larger pumps, now commonly used is integrated water seals.

  7. Introduction of defects in rubber products vulcanizing 1.Lack of glue: due to insufficient weight or poor fluidity, some defects should be found in rubber parts. 2.Degumming: the failure of rubber and frame inserts will result in disengagement or separation. 3.Bubbles: also known as "bulging", because the gas is coated in the rubber epidermis and the formation of local epidermis blistering phenomenon; Thanks for the help and support of Chongqing Feilong jiangli’s Technical department. 4.Rotten bubbles: also known as "pit gas", because the gas has not been discharged from the cavity, so that the die corner of the rubber cavity is less sulfur sticky, and protruding from the surrounding rubber surface phenomenon 5.Gel cracking: a phenomenon of cracking on the glue surface. 6.Under sulfur: the inner surface of the gum is microporous, and the exterior is uplifted and deformed. 7.Sticking mould: the phenomenon that the local glue of vulcanized product is adhered to the wall of the mold cavity. 8.Hot die: also known as curling edge, "bite edge" and so on, refers to the product parting line is not smooth, cracks, serrated waste edge and other phenomena.
  8. Car with 3-5 years, the following 7 rubber parts must be checked and replaced. 1.Engine foot glue The purpose of the engine foot glue is to isolate the engine vibration from the cockpit and fix the engine foot and frame with rubber pads, so as to achieve a certain damping effect and make the engine work smoothly. Usually the engine is oxidized when the driving distance exceeds 50,000 kilometers or the driving time exceeds 5 years. The elastic corpse reduces the damping effect of the engine and can not effectively isolate the vibration of the engine from the frame so that the vehicle leaves the vehicle. Now the boom is loud, but it's fast or abnormal. Many toll collectors often overlook this problem, when the engine appears, think about it, first check the engine itself, but ignore the foot glue oxidation. Replacing the foot glue is not complicated, to the roadside general automobile repair shop can be replaced, the cost is only a few hundred dollars, you can solve the car engine abnormal sound idle jitters problem. 2.Suspension swing arm rubber bearing The suspension swing arm rubber bearings are common in the McPherson front suspension which is now used in driving vehicles. Because of its mechanical characteristics, rubber bearings are needed to cushion and limit vibration and play a supporting role. Many consumers are very strange to suspension swing arm rubber bearings, because it is possible to love the car will not be replaced, but it does affect our car driving experience. Thanks for the help and support of Chongqing Feilong jiangli’s Technical department.Many consumers will feel that after a few years old cars are no longer as easy to drive as new cars, suspension jump response is not very sensitive, and even the road conditions are not very good road surface, the body will jump very seriously, steering at high speed and the stability of the vehicle at high speed is reduced, these are the impact of aging suspension brackets. Replacing the rubber bracket of the suspension arm requires the use of a professional lift, so consumers had better go to a professional body for replacement. 3.Shockproof top rubber bearing The rubber bearing of the shock absorber roof is a cushioning mechanism which can alleviate the vibration of the suspension when the suspension jumps and transmit to the fulcrum of the frame. The early rising part of the vehicle, the inverted suspension is fixed and manufactured. Instead, it uses insomnia so that the body can be used only after the stability of the road surface is reduced. The rubber is used as the material of manufacture, but the design life is five years left. Right. Vehicles passing through the bumpy road caused by suspension ministries to issue abnormal sound, or suspension jump ten people response, not very sensitive, usually suspension too much vibration, resulting in a reduced sense of carriage ride. 4.Crankcase rear oil seal Crankcase oil leakage is a problem many owners will encounter, especially in the use of several years of old cars, crankcase oil leakage let many owners are very distressed. Usually the main reasons for oil leakage of crankcase are: first, there is no use of professional lubricant seal in the manufacturing process, in the use of the process of vibration displacement caused by oil leakage. Secondly, because of the engine oil seal design problems, the use of a period of time after the force caused the deformation of the oil seal groove, and ultimately oil leakage. The above two are the quality problems of the manufacturer, but after more than five years of engine life, crankcase tank with aging aggravated, will produce small cracks, will also lead to oil leakage. 5.Drive shaft damping rubber For some rear-drive and four-drive vehicles after several years of use will encounter the need to replace the transmission rubber shock absorber, the replacement of shock absorber rubber is very time-consuming, labor-consuming, very high, but if not replaced in time will cause permanent deformation damage to the transmission shaft, causing resonance in the front and rear transmission of the car, affecting the line. The car is safe. In our normal driving process, the transmission shaft vibrates with the body and this traditional process is not smooth, so the need for such damping rubber to prevent the transmission shaft should be centralized vertical damage, so the transmission shaft needs transmission rubber shock absorption. 6.Frame sealing strip The replacement of the frame sealing strip is also a problem that many car owners will ignore. The frame sealing strip is pressed on the special rail groove by external force. Exposed to oxidation outside the car, the sealing of the car body will decrease. The infiltrated rain will penetrate into the car body through the crack. The acid rain will corrode the car body inside, and eventually lead to the corrosion. The rust inside the car body is very difficult to deal with. The strength of the car body gradually decreases, and eventually the car body may be rusted through. Therefore, changing the frame seal strip in time is one of the main measures to protect the body from rust. 7.Rubber hose for engine oil circuit The oil pipeline of the engine needs to withstand the high temperature and pressure of the engine, so the consequences are very dangerous once it aging and finally ruptures. Usually the service life of the engine input pipeline is about four years, and cracks will appear on the surface of the aging pipeline as time goes on, which is very easy to spontaneous combustion in the high temperature environment of the engine compartment. Once the driver smells a smell of gasoline through the air conditioner, he must be on the alert.
  9. When the pump is damaged, we should pay attention to the following items when replacing. (1) The real cause of the pump damage should be clear. Before replacing the pump, the radiator fan, thermostat and coolant should be determined. (2) It is likely that pumps with similar shapes but suitable for different types of engines will occur, so before installing the pumps, a comparison should be made between the new pump and the old pump removed, or a check should be made on the part number of the pump and the type of the engine to determine whether the selected pump is suitable for the model being repaired. (3) Water pump installation surface should be carefully cleaned and leveled. (4) When installing the pump, wet the seal ring with coolant first. If you need to use sealant, be careful not to apply too much. (5) Do not use the way of percussion pump shaft to install the pump. You should check the real reason for the difficulty of pump installation. 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 installing bolts in water pumps, they should be tightened progressively in the direction of diagonal according to the prescribed torque, excessive tightening of bolts or causing damage to gaskets. (6) The tension of the pump belt must be strictly controlled according to the adjustment standard. Excessive tension of the belt, will cause bearing overload operation and early damage; and too small tension, easy to produce noise, serious pump can not work properly. Feilong Jiangli warm notes: If you can't replace it by yourself, please go to the warehouse.
  10. It is unavoidable that the breakdown of the automobile water pump is in use. Common faults are as follows: (1) Bearing locking and fracture The causes of bearing failure may be the following aspects: bearing itself quality defects; bearing excessive impact load; product structure design defects; improper pump installation (such as knocking installation, belt tension, etc.) (2) Leakage of installation surface The possible reasons for leakage of installation surface are as follows: uneven application of sealant, resulting in leakage of seam; improper installation of sealing gasket; leakage of pump sealing gasket or improper installation operation. (3) Impeller damage Impeller damage is common in the form of impeller cracking, impeller loose from the pump shaft or impeller corrosion, impeller corrosion will not generally cause engine failure. When the impeller cracks or the impeller is loosened from the pump shaft, the coolant circulation speed becomes slower, which may easily cause the engine temperature to be too high. Damaged impeller may also impact the pump housing when rotating, causing cracking. If your car water pump is broken down , Feilong water pump can give you the prompt help.
  11. Last week
  12. thermostat 1) Function: Change the circulation route and flow rate of cooling water, automatically adjust the cooling intensity, so that the temperature of cooling water is often maintained at 80 to 90 degrees 2) the installation position is installed in the passage of cooling water circulation, usually installed in the outlet of the cylinder head. 3) form: divided into wax type and foldable type. The wax thermostat is equipped with paraffin wax in the space between the rubber tube and the inductor. In order to improve the thermal conductivity, paraffin wax is often mixed with copper or aluminum powder. At normal temperature, paraffin wax is present and the valve is pressed on the valve seat. At this point the valve closes the water path to the radiator, cooling water from the engine cylinder head outlet, through the pump flow back to the cylinder block water jacket for small circulation. When the water temperature of the engine rises, the paraffin wax becomes liquid gradually, and the volume increases accordingly, forcing the rubber tube to shrink, thus producing upward thrust on the upper end of the thrust rod. The upper end of the reversing rod is fixed, so the reversing rod produces a downward reverse thrust on the rubber pipe and the inductor, and the valve opens. When the water temperature of the engine reaches above 80, the valve opens completely, and the cooling water from the outlet of the cylinder head flows to the radiator for large circulation. FAW Audi 100 cars and CA1091 trucks are all made of wax type thermostat. The folding thermostat is made of an elastic, folding, airtight cylinder (made of brass) with a volatile ether inside. The main valve and side valve move up and down with the upper end of the expansion cylinder. The vapor pressure of the liquid in the expansion cylinder varies with the ambient temperature, so the height of the cylinder varies with the temperature. When the engine works under normal thermal condition, that is, the water temperature is higher than 80 C, the cooling water should all flow through the radiator, forming a large cycle. At this point the main valve of the thermostat is fully opened, while the side valve closes the bypass hole completely: when the cooling water temperature is lower than 70 degrees Celsius, the steam pressure in the expansion cylinder is very small, so that the cylinder shrinks to the minimum height. The main valve is pressed on the valve seat, that is, the main valve is closed and the side valve is opened. At this time, the water path from the water jacket to the radiator is cut off. The water in the water jacket can only flow out of the by-pass hole into the pump through the by-pass pipe, and then is pressed into the engine water jacket by the pump. At this time, the cooling water does not flow through the radiator, but follows the water jacket and the pump. Ring, so as to prevent the engine from overcooling, and make the engine hot quickly and evenly: when the engine cooling water temperature in the range of 70-80, the main valve and side valve in the semi-open and closed state, at this time part of the water for large circulation, while the other part of the water for small circulation.Thanks for the help of the Chongqing Feilong Jiangli Auto Parts’ Technical dept. 1) When the cooling water temperature is lower than 76 degrees, the main valve of the thermostat is closed, and the sub-valve opens the cooling water to circulate in a small range between the pump and the water jacket, so that the water temperature rises rapidly. When the water temperature is higher than 86 degrees, the main valve of the thermostat is fully open, the secondary valve is fully closed, and the cooling water flows through the radiator for water circulation to keep the engine at normal working temperature.
  13. Rubber bushing is mainly used in the position of automobile front and rear suspension and other frequent vibration. It plays a vital role in the whole vehicle NVH (Noise Vibration Harshness), and it will be invalid and will affect the whole vehicle noise and driving stability. The failure mode of rubber bushing is not only its own quality control, but also its working environment is one of the key factors affecting its life. Thanks for the support of the Feilong Jiangli technical department. Automobile suspension is a component that connects the frame (or body) with the axle (or direct and wheel). Its main functions are: D mitigates and inhibits vibration or shock caused by uneven pavement to ensure the car has good smoothness; 2 (2) rapidly attenuates the vibration of the body and axle (or wheel); 3 (3) transfer function in the wheel and frame (car) Various forces (vertical force, longitudinal force, transverse force) and moments (braking moment and reaction moment) between the body; 4) to ensure the necessary stability of the vehicle.
  14. One of the categories of automotive rubber products is belt products. Belt products are mainly used in automobiles to transfer torque power and speed, power from the power source engine to the need for power systems and places. It is installed in cooling fan, cooling water pump, brake compressor, booster pump, air conditioning system and steering system. The car belt is mainly V belt. Usually there are three kinds, that is, wrapped V belt, cutting V and multi wedge belt to cut W belt. Cutting V-belt has no coating on both sides, good flexibility, friction coefficient, with a large force, high linear speed, heat dissipation and fatigue resistance and energy-saving characteristics, commonly used rubber MIBR and R. Synchronous toothed joint is used for valve ignition of automotive engines. Its operating conditions are high speed, high power and high temperature. Thanks to Abby from Feilong Jiangli providing the basic data.
  15. Due to the limitation of installation space and performance requirement, automobile engine cooling water pump has the characteristics of small volume, simple manufacture, and is conducive to mass production. The cooling water pump is usually made up of main parts such as pump body, impeller, shaft, bearing, water seal and pulley. According to the different structure of the engine cylinder block, the pump pressurized water chamber can be integrated on the engine cylinder block, and the impeller can also be separately configured as the core functional components of the pump, its diameter, outlet width, blade structure shape and other parameters and structure design directly determine the performance of the cooling water pump. There are many kinds of cooling water pump structure, according to the impeller material is different, can be divided into cast iron impeller, stamping impeller and plastic impeller; according to the impeller has no cover plate can be divided into open impeller and closed impeller; according to the impeller blade shape is different, can be divided into straight blade impeller, single curvature blade impeller and space twisted blade impeller. Feilong Jiangli has all the kinds of impellers. With the development of science and technology, cast iron impellers are still used in the cooling water pumps of trucks, buses and other heavy-duty vehicles and a few self-owned passenger cars. Pressed impellers are mostly used in Japanese passenger cars, plastic impellers are mostly used in European and American advanced countries, and three kinds of impellers are used in domestic self-owned brand cars, but with With the introduction of new technology from abroad, plastic impellers have been used in newly developed machines. When cooling water pumps work, the coolant rotates with the impeller on the one hand, and flows out of the rotating impeller on the other.

  17. Automobile rubber products are indispensable components in automobile parts. According to the different types of cars, each car needs to install about 100-200 kinds of rubber products, to use more than 200-500 rubber accessories. In addition to tires, different sizes of cars vary, and the consumption of rubber materials is about 15-60 kilograms. A car's rubber products (excluding tyres) account for about 6% of the total vehicle cost. There are more than 1000 kinds of non tire rubber products in automobile industry, and there are about 8000 specifications. According to statistics, the automotive industry accounts for more than 70% of the global annual consumption of raw rubber, including 60% of tires, 40% of automotive rubber accessories. High speed, safety, comfort, energy saving and environmental protection are the goals pursued by modern cars. With the development of modern automotive technology, the requirements for automotive rubber products are becoming increasingly stringent and demanding. It is not only required that rubber materials with various special properties meet the new technical requirements of automobiles, but also that rubber materials have higher physical and mechanical properties, such as aging resistance, high temperature resistance, low temperature resistance, new fuel and excellent performance. The dynamic fatigue performance, durable service life and so on. In fact, every high performance of modern automobiles depends on the technical progress of rubber products to provide protection. The performance and quality of automotive rubber products play a crucial role in improving the quality of automobiles. It should be noted here that although rubber products always play a role in a variety of mechanical equipment accessories, but rubber accessories are always about the technical progress and level of the host. Therefore, it can be said that the technical progress and quality level of automobile rubber products can basically reflect the technical level of automobile.

  20. The measuring rod part of the oil gauge The measuring rod part of the oil gauge generally has three structures: steel wire, steel belt (Bian Chi), and many winding wires. Among them, spring steel wire is commonly used in steel wire structure, and the material is hard, which is suitable for the relatively slow bending ruler tube. The multi strand wire is easy to insert and plugged in the bending scale tube, but the price is higher. The material of flat ruler generally chooses 0.8mm~1.2mm stainless steel strip, and the price is relatively low. As the core part of the ruler, the head of a ruler is the most important part of the ruler. In the drawing, it is easy to rub with the ruler tube that matches with it. The particles produced by the friction will fall into the lubricating oil. The unclean lubricating oil will cause great wear to the bearings of the engine. In the indicator part of the scale, the head can be designed as a roller structure, which is not only effective. The scale has reduced the tube pulling force of the ruler and reduced the scraping of the ruler head and the ruler tube. For the oil gauge with steel strip structure, in order to make the gauge clearly indicate the position of the liquid level, it is easier for users to read the oil gauge. Generally, the head of the flat ruler is treated with sand blasting or press mesh, and some rhombic pits can be set on the head of the plastic. These pits are disconnected from each other, so that the oil can climb up the trough under the siphon effect, which affects the accurate reading of the scale.
