Anti-shifting bottom fork connecting structure of motorcycle

Abstract

The invention discloses an anti-shifting bottom fork connecting structure of a motorcycle. A left deep groove ball bearing is fixed on a bottom fork right pipe through a hole clamping ring and a holestep; the relative positions of the bottom fork and a frame are kept unchanged after assembly is completed, axial movement of the bottom fork is eliminated, bolts at the two ends of the bottom fork shaft are screwed to drive a left pedal mounting plate and a right pedal mounting plate, press an outer bushing and a bottom fork inner bushing on the right side, it is guaranteed that the bottom fork inner bushing makes complete contact with a bottom fork shaft tube, and therefore axial movement of the bottom fork inner bushing is eliminated. Therefore, the assembly gap between the frame and the bottom fork is eliminated, and the assembly stress generated for eliminating the gap between the frame and the bottom fork during assembly in a common bottom fork structure form is eliminated. The anti-shifting bottom fork connecting structure has the beneficial effects that the problems that the rear fork moves in the axial direction and is difficult to assemble after a motorcycle frame and the rear fork are assembled are solved, it is guaranteed that no axial gap exists after the rear fork and the motorcycle frame are assembled, the stability of the motorcycle is improved, abrasion is reduced,and the possibility of wheel distortion in the driving process is reduced.

Description

technical field [0001] The invention relates to the field of motorcycle structures, in particular to a motorcycle anti-movement flat fork connection structure. Background technique [0002] The flat fork is an important part of the motorcycle. It belongs to the suspension. The flat fork includes two fork legs. There is a flat fork shaft between the two fork legs. It is also connected to the motorcycle frame. The shaft tube of the steel welded flat fork in the prior art is rotated and matched with the center shaft through the needle bearing, which has the advantages of small rotation resistance and controllable radial clearance, but the axial clearance is difficult. control, the fork legs cannot be axially positioned through needle bearings, and the flat fork is designed to avoid structural interference with the frame, leaving an axial gap between the fork legs and the frame, so in the prior art The flat fork has the technical problem of axial movement, poor structural stabi...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the deficiencies in the above-mentioned prior art, the present invention provides a motorcycle anti-movement flat fork connection structure, which solves the problem of axial movement of the flat fork and difficulty in transfer after the frame and the flat fork are assembled. question
