Role of rear axle bushing.
The main function of the rear axle bushing is to connect the rear torsion beam to the body, achieve correction function, reduce noise, and thus provide good operating stability, ride comfort and ride comfort.
The rear axle bushing is a key component in the rear torsion beam suspension system of automobile, which is located between the rear torsion beam and the body. This design helps balance the up and down movement of the left and right wheels, reduces the shaking of the vehicle, and maintains the stability of the vehicle. When the vehicle turns, the bushing will be deformed to achieve its correction function and reduce noise, thereby improving the vehicle's stability, ride comfort and ride comfort.
The existing rear axle bushings of automotive torque beams usually include an inner casing, a rubber layer and an outer casing. The inner casing and outer casing are made of steel material, and the rubber layer is filled between the inner casing and the outer casing, and the connection is fixed by vulcanization. This structure not only realizes the basic function of the bushing, but also improves the structure of the inner casing through the design, such as the section of the inner casing is roughly elliptical, and a number of adjusting holes are arranged between the installation part and the casing part to adjust the axial stiffness of the inner casing, accurately control the bolt tightening torque, and improve the versatility.
In addition, the design and material selection of rear axle bushings also play an important role in the vehicle's vibration filtering performance and noise control. For example, the bushing made of steel ring and rubber die casting, in which the hard metal shell is used to limit the bushing, to prevent the bushing from being crushed, and the rubber inside can be deformed when subjected to external force, thus playing a role in absorbing shock. This design not only reduces the mutual wear between parts, but also has a certain shock absorption function and improves the comfort of the vehicle.
Rear axle bushing bad what symptom
The symptoms of bad rear axle bushing mainly include shock absorption function failure, chassis vibration and abnormal sound, which will seriously affect the stability and comfort of the car.
The rear axle, as an important part of the vehicle power transmission, is composed of two half Bridges, with differential motion function, and supports the wheel and connects the rear wheel. When the rear axle bushing is damaged, it will lead to the failure of the shock absorption function, and then cause the chassis vibration and abnormal sound. If this kind of vibration is serious, it will directly affect the stability and comfort of the car when driving. Therefore, it is very important to diagnose and repair rear axle bushing problems in a timely manner to avoid adverse effects on the driving experience and vehicle performance.
What good way to install rear axle bushing
The recommended method of replacing the rear axle bushing includes the use of specialized tools and the correct installation steps. First, you need to lift the vehicle and then remove the two rear axle screws and oil tubing. Using the Jetta rear axle rubber sleeve special tool, the rubber sleeve can be easily pulled out. Next, apply yellow grease to the new rubber sleeve and install it back. This method can complete the replacement process more easily than the traditional method.
Use special tools: Jetta rear axle sleeve Special tools are designed to make removing and installing the sleeve easier. The use of this tool can not only improve work efficiency, but also ensure the accuracy of installation.
Applying yellow grease: When installing new rubber sleeves, applying yellow grease can increase the firmness of rubber sleeves, reduce wear and extend service life.
In addition, if it is difficult to disassemble, you can consider using homemade tools or other innovative methods, such as hitting the hole with a hammer, or using a hacksaw blade to cut the iron ring. These methods, while they may require more effort and time, can serve as an alternative in the absence of professional tools.
In general, using the Jetta rear axle rubber sleeve special tool and following the correct installation steps is the recommended way to replace the rear axle bushing. At the same time, it is also very important to choose the appropriate disassembly and installation skills according to the specific situation.
