Abstract

The invention discloses a rear suspension five-way connecting rod device for a bicycle, which comprises a frame, a back lower fork group, a first connecting rod group and a second connecting rod group. The frame is provided with a five-way seat which is fixedly connected to a joint between a seat pipe and a lower pipe; an open-groove accommodating groove is formed in the side direction of the five-way seat; the back lower fork group is provided with two symmetrical back lower fork pipes, a five-way pipe and a back iron seat at the back end which are integrally molded; the five-way pipe is accommodated in the accommodating groove; the back lower fork group is provided with a first pivot point and a second pivot point respectively; one end of the first connecting rod group is pivoted on the first pivot point, and the other end of the first connecting rod group is pivoted on the five-way seat; and one end of the second connecting rod group is pivoted on the second pivot point, and the other end of the second connecting rod group is pivoted on the five-way seat. Through the members, the pivot central distance between the center of the five-way pipe and a wheel of the back iron seat is kept unvaried and the situations of chain device loosening and chain sticking due to impact on the back lower fork group can be avoided.

Description

technical field [0001] The invention relates to a rear suspension system of a bicycle, especially for the distance between the center of the bottom bracket and the center of the rear wheel shaft, which can maintain a small change when the rear chainstay rotates, thereby enabling the chain device on it to drive smoothly. Background technique [0002] The rear shock absorber system of bicycles is mostly used in the mountain bike series. It is mainly used to buffer the impact force transmitted from the rear wheel when riding on a rough mountain road, so as to reduce the impact of the overall frame structure due to the impact force. Wear and tear, and improve the comfort of the ride. [0003] The suspension system of the general rear shock absorber mainly includes components such as shock absorbers, rear chainstay tubes, rear upper fork tubes, and several connecting rod groups; , which produces related actions, on the one hand, the impact force is transmitted to the shock absor...
