Novel front-suspension system of heavy-load motorcycle

Abstract

The invention relates to a novel front-suspension system of a heavy-load motorcycle, which comprises two parallelly arranged extension-pipe-type front shock absorbers; front fork pipes relatively move in a bottom cylinder of the front shock absorber; the upper end of the front fork tube is mutually fixed with an upper connection plate of a direction column; a lower connection plate of the directional column is fixed at the middle part of the front fork tube; an upper fixed connection plate and a lower fixed connection plate are arranged between the lower connection plate of the directional column and the bottom cylinder of the front shock absorber corresponding to the lower connection plate; the upper fixed connection plate is respectively sheathed with the left front fork tube and the right front fork tube; the lower fixed connection plate is respectively sheathed with the bottom cylinder of the left shock absorber and the bottom cylinder of the right shock absorber; and an elastic device is arranged in the center between the upper fixed connection plate and the lower fixed connection plate. Because the above technical scheme is adopted, a plurality of beams are added on an overhanging part of the front shock absorber, so as to ensure the parallelism of axial lines of the left shock absorber and the right absorber of the front suspension of the heavy-load motorcycle, thus the condition that the overhanging part is not easy to deform is guaranteed, the lateral rigidity of the front fork tube and the cooperativity of the left shock absorber and the right shock absorber are enhanced, the directional offset is not easy to occur, and the traveling safety and comfort of a front shock absorbing system are improved.

Description

technical field [0001] The invention relates to a front suspension system for motorcycles, in particular to a novel heavy-duty motorcycle front suspension system, which is mainly suitable for heavy-duty two-wheeled motorcycles and tricycles. [0002] Background technique [0003] The existing front suspension system used on heavy-duty two-wheeled motorcycles and tricycles mostly adopts the front suspension system of common two-wheeled motorcycles, such as figure 1 , figure 2 As shown, this front suspension system suitable for ordinary two-wheeled motorcycles includes two front shock absorbers arranged in parallel, and the front shock absorbers are of telescopic tube type. Relative movement in the front shock absorbing bottom tube 3; the lower end of the corresponding front shock absorbing bottom tube 3 is provided with an axle hole for installing and fixing the front wheel shaft, and the front wheel of the motorcycle is fixed on the two front wheels through the front whee...

AI Technical Summary

Problems solved by technology

[0005] The present invention aims to solve technical problems such as poor load-carrying capacity, poor lateral rigidity, difference in rigidity of left and right damping springs, and easy occurrence of direction deviation in the current motorcycle front suspension system, thereby improving driving safety and improving the performance of the front suspension system. comfort
