The buffer blocks of different structures have some different functions. For a passenger car, a shock absorber with a helical spring can act as a first stage vibration absorber to prevent the external shock from acting directly on the shock absorber, thereby prolonging the life of the shock absorber.
The car itself has a lot of buffer components, do not know what you said, but the buffer block means its buffer action, such as the engine above is to reduce engine vibration, damping is above ground to reduce the vibration of the body, too much.
Most of the cushion blocks of modern cars are made of porous polyurethane material, and rubber materials are gradually replaced by them. The porous cushioning block made of polyurethane material has the advantages that the following rubber can not be replaced: the quality is small, about the same size, and the rubber buffer block 1/2 has large deformation and has good nonlinear characteristics.
The automobile buffer block is a device that can limit the maximum deformation of the suspension. It reduces the direct impact of the axle on the frame (or body), preventing excessive deformation of the elastic elements. The buffering block is composed of a rubber block, a steel plate and a bolt. Some cushion blocks are made of porous polyurethane, and the inner cavity is hollow.
