The automobile damping top rubber is made of plastic rubber, which has the function of cushioning and damping. It is commonly known as the pressure top rubber of the damping frame support with spring seat ring. It is used to cushion the impact of the shock absorber spring and the vehicle body. When driving on uneven roads, each top rubber bears the impact of more than one quarter of the weight of the vehicle body; When the complete pressure apex angle passes through some speed bumps, lift the body up after the tire is completely on the ground. It feels a little upward, and the comfort is particularly good; When the shock absorber reaches the highest point or the lowest point, the last shock absorption function, such as passing through the pit, when the shock absorber pier reaches the bottom, it will be a "bang", and there will be a "bang" without top glue.
