Front suspension system for motorcycle

Abstract

The invention relates to a front suspension system for a motorcycle, which comprises a frame and a front wheel positioned in front of the frame. The front wheel is fixedly connected with a steering knuckle through a front wheel hub component, the steering knuckle is respectively connected with a steering mechanism and a shock-absorbing mechanism, the shock-absorbing mechanism comprises a rocker only transversely arranged on a single side of the front wheel, the front of the rocker is connected onto the steering knuckle, and the rear of the rocker is connected with the frame through a shock absorber. The front suspension system separates a steering function from supporting and shock-absorbing functions, is capable of absorbing and releasing impact of a road surface on the front wheel to a maximum degree, so that shock of steering handlebars and a motorcycle body is reduced, and driving comfortableness and maneuverability of the motorcycle are improved.

Description

technical field [0001] The invention relates to a front suspension system of a motorcycle. Background technique [0002] The commonly used motorcycle front suspension system generally includes two structural forms: double-fork front fork plus lower link type TLAD anti-dive suspension structure and double-fork front fork plus double straight front shock absorber suspension structure. Although the double-fork front fork and lower link type TLAD anti-dive suspension structure can reduce the front shock caused by the excessive contraction of the shock absorber spring during braking, it also has the defects of insufficient road feeling and low sports performance; Although the double-fork front fork and double straight-tube front shock absorber suspension structure has improved the road surface feeling and the lack of sports performance, it still cannot get rid of the excessive contraction of the front fork straight-tube front shock absorber spring when braking at high speed. sho...

Problems solved by technology

Although the double-fork front fork and lower link type TLAD anti-dive suspension structure can reduce the instability of the front of the car caused by the excessive contraction of the shock absorber spring during braking, it also has the defects of insufficient road feeling and low sports performance; Although the double-fork front fork and double straight-tube front shock absorber suspension structure has improved the road surface feeling and the lack of sports performance, it still cannot get rid of the excessive contraction of the front fork straight-tube front shock absorber spring when braking at high speed. shortcoming

The characteristic of these two front suspension systems is that the front fork and the shock absorber together undertake the functions of vibration reduction, support and steering. The disadvantage of this structure is that the friction is relatively large, and the vibration feeling transmitted from the ground to the hands is obvious. Driving comfort is poor at large amplitudes
