The broken performance of the shock absorber strut mounts

As the parts rub against each other, the shock absorber wears out quickly, so strut mounts come in handy. As people have higher and higher requirements for the comfort and smoothness of automobiles, the structure of pure rubber blocks can no longer meet the requirements. On this basis, people have developed rubber suspensions with additional mass and rubber suspensions with parallel hydraulic shock absorbers. The following is a related introduction to the broken performance of the shock absorber strut mounts.

The characteristics of shock absorber strut mounts

1. The shape can be determined freely, and the hardness can be controlled by adjusting the components of the rubber formula, which can meet the requirements for stiffness and strength in all directions;

2. The internal friction is large and the shock absorption effect is good, which is conducive to crossing the resonance zone and attenuating high-frequency vibration and noise;

3. The modulus of elasticity is much smaller than that of metal, which can produce greater elastic deformation;

4. There is no sliding part, easy to maintain;

5. Convenient installation and disassembly;

6. The impact stiffness is higher than the static stiffness and dynamic stiffness, which is conducive to impact deformation.

The material of the shock absorber strut mounts is rubber, which acts as a buffer and shock absorber. When the tire is subjected to bumps on the bumpy ground, it can reduce the direct impact on the car.

The working principle of shock absorber strut mounts

Vibration absorption: This type of shock-absorbing rubber is mainly used for the connection between the engine and the body. In this state, the engine is the source of vibration. The function of the shock-absorbing rubber is to absorb the vibration generated by the engine, while also reducing the vibration of the engine itself.

Vibration reduction: This type of shock-absorbing rubber parts are mainly used for the connection between the chassis and the body. In this state, the chassis wheels are the vibration source. The function of the shock-absorbing rubber is to quickly reduce the vibration generated by the road surface and the wheels through high damping. Prevent vibration from being transmitted to the body through the chassis.

The shock absorber of a vehicle is composed of a spring and a shock absorber. The shock absorber is not used to support the weight of the car body, but to suppress the shock when the spring rebounds after absorbing the shock and absorb the energy of the road impact.

The spring plays the role of alleviating the impact, changing the "high energy one impact" into "small energy multiple impact", and the shock absorber gradually reduces the "small energy multiple impact".

If you have driven a car with a broken shock absorber, you can experience the bouncing of the aftermath of the car going through every pothole and ups and downs, and the shock absorber is used to suppress this kind of bounce.

Without the shock absorber, the rebound of the spring cannot be controlled. When the car encounters a rugged road, it will have a serious bounce. When cornering, the tire's grip and tracking will be lost due to the up and down vibration of the spring.

Symptoms of broken strut mounts of shock absorber

1. The driving comfort deteriorates, and the sound is particularly obvious when passing through the convex road, which seems to be a problem with shock absorption.

2. The friction sound of the tire becomes louder.

3. The steering wheel is offset, which means that the steering wheel is crooked when you are driving in a straight line.

4. If you adjust the direction in place, it will make a squeaking sound.
