Problems solved by technology

Its shortcoming is: when the motorcycle runs at high speed on uneven roads, the connecting rod drives the piston to move at a high speed in the working cylinder. The damping oil inside will not be able to flow back into the working cylinder in time, and a damping vacuum will appear when the piston goes down again, causing the built-in damper to lose its damping force instantly, affecting the riding comfort of the motorcycle
In addition, since the left and right shock absorbers have shock absorbing springs and shock absorbing oil, they are very heavy, and the lower end of one of the shock absorbers is also equipped with a front wheel brake device, which affects the gravity distribution of the whole vehicle.

Abstract

A reversely arranged front vibration-damping unit of motorcycle is composed of the first vibration damper using spring as its vibration mechanism and the second vibration damper with an internal damper consisting of piston, connecting rod and cylinder. Each vibration damper comprises bottom barrel, end cover, fork pipe and external barrel. Its advantages are simple structure and light weight.

Description

technical field [0001] The invention relates to a shock absorber for a vehicle, in particular to an inverted front shock absorber for a motorcycle. Background technique [0002] As we all know, the inverted front shock absorber of a motorcycle is the suspension of the motorcycle driving system. It supports the body and transmits traction, which is closely related to the safety of the vehicle. At the same time, it is a performance part. The comfort of the occupants also has an impact. Most of the existing motorcycle inverted front shock absorbers adopt a left and right double shock absorber structure, and the left and right two shock absorbers have the same structure. [0003] According to the installation direction of the fork tube, the front shock absorber is divided into a positive shock absorber and an inverted shock absorber. The Chinese invention patent with the notification number CN2621963Y provides a structure of an inverted front shock absorber, which is mainly com...
