Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0010] As shown in Figure 1, the shock absorber 2 is formed by one-time cold drawing of high-precision cold-drawn steel pipe or cold-drawn steel pipe, and its bottom end is welded with a joint 1. The joint 1 is a steel casting or forging formed by paraffin precision casting. The fender support 8 is welded on the shock tube 2, and the fender support 8 is a steel casting or forging formed by paraffin precision casting; There is a composite sleeve 6, the composite sleeve 6 is a copper-based composite sleeve or an oil-free bearing or a powder metallurgy sleeve, and an expansion joint is provided on the composite sleeve, which is convenient for installation and replacement, and avoids direct friction between the inner wall of the shock-absorbing cylinder 2 and the outer wall of the shock-absorbing column 13; Fix the guide sleeve 4 in the inner cavit...

Abstract

The present invention relates to a front shock absorber for three-wheeled motorcycle and comprises a shock absorber tube (2), a shock absorber column (13) and a joint (1). The shock absorber column is arranged in the shock absorber tube and is connected to the joint of the shock absorber tube through a guide rod (3) and the shock absorber tube (2) is molded by stretching high-precision cold-drawn steel tube or cold-drawn steel tube, with large carrying capacity, high impact resistance and reduction of manufacturing cost; a guide sleeve (4) on the upper end of the guide rod and a guide sleeve (9) of the internal cavity of an expanding body on the upper end of the shock absorber tube are powder metallurgy sleeve or engineering plastic sleeve, with good wear resistance and long service life; the lower end of the shock absorber column is provided with one or more sections of composite sleeves (6), and the composite sleeve is copper-based or oil-free bearing or powder metallurgy sleeve, avoiding direction friction between the shock absorber column and the shock absorber tube; the two guide sleeves and the composite sleeve support the shock absorber column commonly so that the shock absorber column can do linear reciprocating motion, with the function of guidance and protection and greatly reduction of friction coefficient. The shock absorber has the advantages of low cost, wear-resistant, low noise and good corrosion resistance.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a front shock absorber used on a three-wheeled motorcycle. Background technique [0002] The front shock absorber currently used on three-wheeled motorcycles, the shock absorber, the joints on the shock absorber, the fender bracket, etc. are casted in one piece of aluminum, which has high cost, low strength, complicated processing and short service life. Contents of the invention [0003] In order to overcome the disadvantages of the high cost of the aluminum material used in the shock absorber in the prior art, the purpose of the present invention is to provide a shock absorber with reasonable structure, simple processing, low cost and long service life. front shock absorber for three-wheeled motorcycles. [0004] The technical scheme adopted in the present invention is: a front shock absorber of a three-wheeled motorcycle includes a shock absorber, a shock absorber, and a joint, the shock...
