Rear shock absorber mounting base structure of motorcycle frame

Abstract

The invention discloses a rear shock absorber mounting base structure of a motorcycle frame. The mounting base structure comprises a frame tube and a cross tube, wherein one end of the cross tube is fixedly welded in the middle of the frame tube; a reinforcing plate is welded in an acute-angle included angle defined by the frame tube and the cross tube, the cross section of the reinforcing plate is in a triangular shape, the longitudinal section of the reinforcing plate is in a U shape, and the reinforcing plate, the frame tube and the cross tube are fixedly welded to form a sealed space; the longitudinal section of the part of the reinforcing plate welded with the frame tube and the cross tube is in an R shape, and R-shaped lap joint among the reinforcing plate, the frame tube and the cross tube can be realized; a tapered hole is formed in a connection between the frame tube and the cross tube, a tapered boss matched up with the tapered hole is arranged at the top of the cross tube, and the tapered hole and the tapered boss are fixedly welded. The rear shock absorber mounting base structure is large in contact area between the reinforcing plate and the frame, good in stability, light in local quality, good in connection strengthening effect, high in rigidity and intensity, high in impact resistance, and convenient to install.

Description

technical field [0001] The invention relates to a motorcycle rear shock absorber mounting seat structure, which belongs to the field of motorcycle manufacturing. Background technique [0002] In the production of existing motorcycles, when the mounting seat structure used for motorcycle rear shock absorbers is connected to the frame, the welding area is too small, the impact resistance is low, and the safety performance cannot be well guaranteed , and the strength of the rear shock absorber mounting seat itself cannot withstand the impact of the motorcycle shock absorber on the shock absorber seat during complex road surfaces, which increases potential safety hazards. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a motorcycle rear shock absorber mounting seat structure, which increases the welding contact area, facilitates welding positioning, and reduces manufacturing c...
