Motorcycle rear shock absorber construction

Abstract

The invention relates to a motorcycle rear shock absorber structure. The shock absorber at least comprises an upper seat, a lower seat, a damper and a spring, wherein the upper seat comprises an upper connecting part which can be combined with a motorcycle frame; the lower seat is provided with a lower connecting part which can be combined with a power unit; the damper is provided with an actuating rod; the spring is formed integrally; the spring can be divided to a compact part and a sparse part according to the distance of spring coils; the compact part of the spring is formed by piling at least two spring coils; the sparse part is divided to an upper sparse part and a lower sparse part by the compact part; a baffle area can be defined on the spring by the compact part; and by utilizing the baffle area, the resonance frequency of the spring caused by the operation of the power unit can be changed, thus the compression range of the spring can be effectively reduced without increasing the production cost and the effect of increasing the rigidity and strength of the spring can be realized.

Description

【Technical field】 [0001] The invention relates to a motorcycle rear shock absorber structure, in particular to a shock absorber structure capable of increasing spring rigidity. 【Background technique】 [0002] In response to uneven road conditions and potholes, general motorcycles are equipped with rear shock absorbers to reduce the shaking and jumping of the body, so as to avoid damage to related components of the motorcycle due to vibrations, and to increase the riding comfort of passengers. Comfort, regardless of the appearance of the rear shock absorber, the spring is one of the main rear shock absorber components. The spring is used to absorb the vibration of the motorcycle during driving by using the expansion and contraction deformation of the spring after it is stressed. [0003] And known motorcycle rear shock absorber 1, please refer to figure 1 As shown, the rear shock absorber 1 includes an upper seat 11, the upper seat 11 is combined with an actuating rod 12 dow...

AI Technical Summary

Problems solved by technology

[0008] However, the known motorcycle rear shock absorber 2 divides the two springs 25 into upper and lower sections, which will increase the manufacturing cost of the shock absorber 2, and the positioning effect of the spring 25 is likely to be poor when positioning, and the spacer 26 will move up and down with the compression of the spring 25, and then the spacer 26 will often slide on the damper 23 and cause wear
