First of all, let us get to know the car strut mount:
All cars have shock absorbers, the lower part of the shock absorber is connected to the control arm of the suspension, and the upper part is connected to the body. There is a buffer rubber between the shock absorber and the body, which is called the shock absorber strut mount. The function of strut mount is to buffer the vibration and prevent the vibration from being directly transmitted to the body. For example, when you drive over the speed bump, there will be a feeling that the body is supported by a slight amount after the tire falls to the ground completely, that is very comfortable; on the other hand, the strut mount of the shock absorber also has the effect of the sound insulation. The tire noise generated by the tires and the ground also needs the strut mount to be reduced, and when the car passes over the bumpy roads, it can also reduce the direct impact on the car.
The strut mount is the last shock absorber of the car, it helps the spring to reduce the impact force when the spring is in action. When the spring is pressed to the bottom, you will feel a relatively strong impact from the wheel generally. When the shock absorber rubber is still in good condition, the impact sound is “pengpeng”, and when the shock absorber fails, the impact sound is “dangdang”, and the impact force is very strong, it will not only cause damage to the shock absorber, but also may cause deformation of the hub.
The interaction between the molecules of the strut mount will hinder the movement of the molecular chain, and it has the characteristics of viscosity, so that the stress and strain are often in an unbalanced state. The curly long-chain molecular structure of rubber and the weak secondary force between molecules make the rubber material exhibit unique viscoelastic properties, so it has good shock absorption, sound insulation and cushioning properties.
The performances of the broken rear shock absorber strut mount are as follows:
The comfort becomes worse, and the sound of thumping when passing the speed bump is particularly obvious, which is a problem with shock absorption.
The tire pressure increases, and the sound of booming can be heard in serious cases.
The direction becomes inclined, which means that the steering wheel is crooked when driving in a straight line, and it will not go straight when it is straightened.
It will make a squeaking sound when it is steered in place.
