Motorcycle bottom fork mounting assembly and motorcycle thereof

Abstract

The invention discloses a motorcycle bottom fork mounting assembly and a motorcycle thereof. The bottom fork mounting assembly comprises a left axle tube, a right axle tube and a bottom fork axle, wherein the left axle tube and the right axle tube are arranged on two sides of an engine of the motorcycle and the bottom fork axle passes through the engine of the motorcycle; the left axle tube passes through a left bush, the right axle tube passes through a right bush, and the left axle tube and the right axle rube are sleeved outside the bottom fork axle; and by taking the right end face of a left frame of the motorcycle as a reference plane, the two axial ends of the left bush are tightly pressed between the engine and the left frame of the motorcycle, so that a longitudinal central plane between the left frame and the right frame of the motorcycle is overlapped with a longitudinal central plane of the engine of the motorcycle. The invention can make the longitudinal central plane between the left frame and the right frame of the motorcycle overlapped with the longitudinal central plane of the engine of the motorcycle, realizes alignment in the assembly process, and ensures the safety and stability of the whole motorcycle; and in the mounting process, the deforming force is not needed to be applied to the frames and the service life of the frames and the bottom fork mounting assembly is prolonged.

Description

technical field [0001] The invention relates to a motorcycle component and the motorcycle thereof, in particular to a component assembly for installing a rear wheel of the motorcycle and the motorcycle thereof. Background technique [0002] The flat fork is an important part of the motorcycle and belongs to the suspension device. The flat fork comprises two leg pipes, the front ends of the two leg pipes are respectively fixedly connected with axle pipes, and the rear end is provided with a rear axle hole for installing the rear wheel. The flat fork shaft sleeve fits on the flat fork shaft of the motorcycle. In order to ensure a certain relative rotation angle and ensure the shock absorption effect of the rear wheel, it is necessary to rotate and cooperate between the flat fork shaft tube and the central shaft, and have a reasonable gap. In the prior art, there are two structures for the installation of the flat fork. One is that the flat fork is directly installed on the f...

AI Technical Summary

Problems solved by technology

[0004] In view of this, the present invention provides a motorcycle flat fork installation assembly, which can avoid the problem in the prior art that the installation of the flat fork must make the frame deform and it is difficult to ensure that the longitudinal center of the engine of the motorcycle coincides with the longitudinal center of the frame , so that the longitudinal center of the engine of the motorcycle and the longitudinal center of the frame of the motorcycle are guaranteed to coincide during the assembly process, thereby ensuring the safety and stability of the motorcycle and prolonging the service life of the flat fork installation assembly
