Motorcycle cradle connector

Abstract

The motorcycle cradle connector includes one lower supporting rack for the rear damper fixed in the middle part of the rear fork connecting pipe, two parallel rockers in the same structure with triangularly distributed installation holes for hinging with the rear damper and a link rod, one outer liner tube fixed to the lower supporting rack, and one inner liner tube inside the outer liner tube with sliding bearing in between. The inner liner tube is screwed to the rockers, and the rockers and the inner liner tube can rotate relatively to the outer liner tube. The present invention has smart design, simple structure, simple assembling, capacity of raising the damping effect and riding comfort, low production cost and high assembling efficiency.

Description

technical field [0001] The invention belongs to the technical field of motorcycles, and in particular relates to a motorcycle cradle connection device. Background technique [0002] The structure of the existing motorcycle cradle connecting device is shown in Figure 4, Figure 5 and Figure 6, and the mounting bracket 2 under the rear shock absorber is welded and fixed on the rear fork connecting pipe 1d; Composed of a rod 10 and a bushing 12, two rocker arms 5 with the same structure are arranged in parallel, and there are mounting holes in a triangular distribution on the rocker arms 5, wherein the mounting holes at the corners of the triangle are hinged to the lower end of the rear shock absorber 9, A sleeve 12 is welded in the mounting hole at the front bottom corner of the triangle, and the sleeve 12 is connected to the frame connecting rod mounting bracket 11 through bolts, while the mounting hole at the rear bottom corner of the triangle is hinged with one end of the co...

AI Technical Summary

Problems solved by technology

Because the rocker arm 5 in the prior art rotates around the frame connecting rod mounting bracket 11, the telescopic amount of the rear shock absorber 9 is limited by the arm length between the top corner mounting hole on the rocker arm 5 and the front bottom corner mounting hole. , because the arm length between the two holes is relatively short, the compression amount of the rear shock absorber 9 is relatively small, and the energy absorbed by the rear shock absorber 9 is also small, so that the effect of shock absorption is not ideal, and the driving comfort poor

At the same time, the structure of the cradle and the assembly relationship between the cradle and the rear shock absorber 9, the connecting rod 10 and the frame connecting rod mounting bracket 11 are complicated, and the requirements for assembly accuracy are relatively high, so the manufacturing accuracy of related parts requires Higher, resulting in higher manufacturing costs
