Description
Technical Field

Background
Shock absorbing topcoats are a highly elastic sealing material used between the suspension system of an automobile and the body of the automobile and are generally installed between the top of the shock absorber and the body of the automobile. Its main function is damping and reducing vibration and noise of car body. The damping top rubber has good elasticity and moderate compactness, so that the damping top rubber can bear certain force and pressure when the automobile vibrates and runs.
However, the following symptoms can occur after the shock absorbing top glue of the automobile is damaged:
1. abnormal sound: when the shock-absorbing top rubber is damaged due to serious abrasion, the shock absorber of the vehicle can make abnormal sounds when working, and the direction becomes inclined or the steering wheel is inclined when running straight.
2. Directional offset: when the shock attenuation top glue appears damaging, the vehicle direction can appear slight skew, is difficult to the alignment to and the dynamics of aligning is low scheduling phenomenon.
3. Noise becomes large: due to the lack of the buffering of the top rubber, the shock absorber can transmit the absorbed shock and impact to the cab from the frame without reservation in the working process.
4. In-situ steering abnormal sound: even if the shock absorber is not working, the steering wheel can be driven in situ to generate very obvious abnormal sound due to excessive abrasion and damage of the top rubber.
Therefore, the abrasion resistance test for the damping top rubber is very necessary, and the service life of the damping top rubber can be estimated through the detection in advance, so that the damping top rubber can be replaced periodically in time. However, in the conventional top rubber of the shock absorber, a local position is in contact with a car body during use, after a long time, a contact part is worn out due to vibration of the car, even a metal body is worn out, and the car body extrudes the top rubber when the car vibrates the top rubber, so that a certain compression amount of the top rubber is relatively generated.
