Multi-link vehicle tilt back mechanism

Abstract

The utility model relates to a multi-link vehicle reclining mechanism, which is used to solve the problem that the existing vehicle reclining mechanism cannot be used for a long time. The multi-link vehicle tilting return mechanism of the present invention includes a fixed shaft, a rotating member, a right connecting rod group and a left connecting rod group, the fixed shaft is fixed to the rear frame, and the rotating member is fixed to On the front frame, the rotating member is rotatably sleeved on one end of the fixed shaft, the right connecting rod group is connected to the rear frame and one side of the rotating member, and the left connecting rod group is connected to the rear vehicle frame and the other side of the rotating member.

Description

technical field [0001] The invention relates to a mechanism used for a tricycle, in particular to a multi-link vehicle tilting and returning mechanism which can be assembled on a tricycle frame to help the tricycle return to the right after turning inward. Background technique [0002] Please refer to figure 1 , which is a kind of existing vehicle leaning back mechanism 9, the existing vehicle tilting mechanism 9 has a rotating part 91 fixed on the front frame of the tricycle frame, and has a fixed shaft 92 fixed on the front frame of the tricycle frame For the rear frame, the rotating member 91 is rotatably sleeved on one end of the fixed shaft 92; the existing vehicle tilting mechanism 9 also has a plurality of elastic bodies 93 arranged on the inner wall of the rotating member 91 and the fixed shaft. Between the outer walls of the shaft 92. [0003] Accordingly, when the tricycle is cornering, the rotating member 91 can rotate relative to the fixed shaft 92 to compress ...

AI Technical Summary

Problems solved by technology

[0004] However, since the plurality of elastic bodies 93 are mostly made of elastic materials similar to rubber, and the material is less stable in tolerance to temperature and pH value, it often has poor elasticity after using for a period of time, and even It is the occurrence of cracks and failures, which require frequent and regular maintenance

However, during the period of regular maintenance, the effect of the plurality of elastic bodies 93 assisting the front frame to return will gradually deteriorate, and if the elastic body 93 is accelerated to aging due to changes in the use environment, it may also be replaced during maintenance. Before the new elastic body 93, there was a situation where the front frame could not be properly assisted, which led to an overturning accident of the tricycle, so there were doubts about the safety of use
