Car with 3-5 years, the following 7 rubber parts must be checked and replaced.


Recommended Posts

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 jianglis  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.

      1.Difference between diesel powered refrigeration unit and engine driven refrigeration unit
      Diesel powered refrigeration unit: Independent and non-independent refrigeration units are divided according to power source. Independent refrigeration unit (Diesel powered refrigeration unit) means that the refrigeration unit has a separate power source and the unit itself has an independent power source.
      Generally speaking, diesel powered reefer unit is integrated structures, but there are also modified split structures (this structure is generally hoisted on the beam of the reefer truck). This type of unit itself has an engine and a generator that provide power and electricity to the refrigeration system Device. It can work independently without being restricted by the working state of the truck engine.
      Non-independent refrigeration unit (Engine driven refrigeration unit😞 As the name implies, it is a refrigeration unit that cannot work independently. This type of unit has no power unit and must rely on the truck engine to drive the compressor to work.
      The engine driven refrigeration unit can also be divided into an integral structure and a split structure from the structure. The split structure also includes three types of condenser front type, condenser top-mounted type and condenser bottom-mounted type (bottom-mounted or concealed); but the condenser front-mounted structure is the most common structure in split non-independent refrigeration units.

      2.Advantages and disadvantages of diesel engine refrigeration unit and engine driven refrigeration units
      Independent refrigeration unit
      Advantages: The advantage of diesel engine refrigeration unit is stability and reliability, which is also the most needed for refrigerated trucks. Since the diesel engine refrigeration unit has a separate source of power output, the refrigerator can still work when the refrigerated vehicle is turned off or the refrigerated vehicle has an engine failure, so as to ensure that the goods in the refrigerated vehicle will not deteriorate.
      Integrated independent refrigeration unit
      Disadvantages: The disadvantage of independent refrigeration units is that they are expensive and maintenance is more complicated than non-independent refrigeration units. Due to the addition of a set of power systems, independent refrigeration units are more complicated than non-independent refrigeration units in terms of maintenance, and independent refrigeration units are relatively more technically complex and more expensive.
      Non-independent refrigeration unit
      Advantages: The advantages of non-independent refrigeration units are low price, simple structure and easy maintenance.
      Disadvantages: The disadvantage of the non-independent refrigeration unit is that it relies too much on the power source of the refrigerated vehicle. When the refrigerated vehicle engine stops working, the non-independent refrigeration unit loses power support and the refrigeration system stops working. If the door is frequently opened when the vehicle is turned off, the large loss of cold air in the refrigerated box causes the temperature in the box to rise, or the refrigerator will stop cooling when the vehicle fails (engine failure), and the cargo in the vehicle is easily lost.
      3.Choice of independent refrigeration unit and non-independent refrigeration unit
      From the price point of view: If your budget is relatively sufficient and have strict temperature requirements (the required temperature should be at least minus 10 degrees below) ) It is recommended to use a diesel powered refrigeration unit.
      In terms of the length of transportation distance: For short-distance distribution within the city or between districts and counties, it is recommended to use non-independent units, which not only lower the procurement cost, but also easy to repair even if there is a failure; For long-distance transportation, it is recommended to use independent refrigeration units, because Even if the vehicle engine stops working during long-distance transportation, the refrigerator can still cool normally to ensure the safety of the transported items.
      In terms of vehicle models: Generally speaking, light trucks with a body less than 7 meters are recommended to use non-independent units. For trucks and semi-trailers above 7 meters, independent refrigeration units are better.
