In the working process of a hydraulic shock absorber of an automobile suspension system, a piston rod reciprocates in a working cylinder, and oil generates damping force through a valve system. Under the condition of a large bumpy road, the damping of the shock absorber is expected to be increased, the shock absorber can effectively absorb mechanical energy, rigid impact is avoided, and the shock absorption effect is achieved. The most comfortable riding experience is brought to the rider. According to the requirement of suspension stroke, a check ring is arranged at the corresponding position of a piston rod of the shock absorber to limit the maximum stretching length of the shock absorber; in order to avoid damage and abnormal sound caused by the contact process of the check ring and the guide seat, the non-metal buffer washer is placed on the check ring, so that the direct contact between the check ring and the guide seat is avoided, the impact noise is reduced, and a very limited buffer effect is achieved. In order to obtain a desired damping effect and suppress roll of the vehicle body, it is desirable to generate a large peak damping force before the extension stroke of the automotive suspension system reaches the extension limit position. Normally, a return spring is placed on the check ring, when the shock absorber is stretched to a certain position, the spring is compressed to generate rebound force, and the rebound force and damping force generated by the valve system jointly generate resistance for inhibiting the suspension from being stretched continuously; the structure is generally provided with plastic buffer washers between the spring and the retainer ring and between the spring and the guide seat, but when the spring is compressed to be in a close circle, noise and obvious impact feeling can still be generated. The structure is that a plastic spring is placed on the retainer ring; the plastic spring has larger deformable amount, plays a better buffer role, can restrain the side inclination and avoids the noise and impact generated when the metal springs are combined; due to the limitation of material performance, the high loss is serious in the use process of the plastic spring, so that the maximum length of the shock absorber is obviously changed, and the whole vehicle is adversely affected.
