Definition, Function, and Material Classification of Shock Absorber Buffer Blocks

The shock absorber buffer block is a rubber product installed in the automobile suspension system. It mainly plays the role of buffering and protecting the shock absorber.‌

It is made of high elasticity and high toughness rubber or other materials, usually installed at the coil spring. It is used to limit the maximum deformation of the suspension, reduce the direct impact of the axle on the frame, and prevent excessive deformation of the elastic elements.‌。

The functions of shock absorber buffer blocks mainly include：

‌Improve driving stability‌： By absorbing impact loads, reducing body vibration and improving driving stability and comfort ‌

‌Protect shock absorber‌： Prevent the shock absorber from being damaged due to excessive instantaneous pressure and extend the service life of the shock absorber.

‌reduce noise‌： Absorb suspension system noise and reduce noise pollution during driving ‌。

‌Improve passability‌： Restore the original height of the car body, improve the stability when passing through the deceleration road, shorten the braking distance, and improve safety.

The material classification of shock absorber buffer blocks mainly includes：

‌Rubber products‌： Traditional buffer blocks are made of rubber with high elasticity and toughness, but are gradually being replaced by more advanced materials ‌。

‌polyurethane (PU) Material ‌： Modern cars mostly use buffer blocks made of porous polyurethane materials, which have the advantages of small mass, large deformation, and better nonlinear characteristics. .。
