Rubber Spring Pad 31336775582 For BMW F18

There are some differences between the upper spring pad and the lower spring pad in the position and function of the shock absorber system.

1. Location: The upper spring pad of the shock absorber is located between the shock absorber and the vehicle body, while the lower spring pad is located between the shock absorber and the wheel.

2. Function: The spring pad on the shock absorber mainly plays the role of buffering and protection. It is located between the shock absorber and the vehicle body, which can reduce the vibration and impact caused by uneven road surface, acceleration, braking and other factors, improve driving comfort, and protect the vehicle body and chassis components. The lower spring pad mainly plays the role of adjusting the characteristics of the suspension system. It is located between the shock absorber and the wheel, which can adjust the stiffness and rebound characteristics of the suspension system and affect the suspension comfort, stability and handling performance of the vehicle.

3. Material and design: The spring pad on the shock absorber is usually made of elastic materials such as rubber or polyurethane, which has certain elasticity and shock absorption performance. Its design is generally simple, mainly considering its elasticity and durability. The lower spring pad is usually made of metal material, such as steel plate or rubber-metal composite material. Its design is more complicated, considering its stiffness, elastic coefficient and damping characteristics.

To sum up, there are differences in position and function between the upper spring pad and the lower spring pad of the shock absorber. The upper spring pad of the shock absorber mainly plays the role of cushioning and protection, while the lower spring pad mainly plays the role of adjusting the characteristics of the suspension system. Their materials and designs are also different to meet their respective functional requirements.
