Assembling method for backswing starting mechanism of motorcycle

Abstract

The invention discloses an assembling method for a backswing starting mechanism of a motorcycle. An assembling assistive device which comprises a connecting plate, a connecting rod, a handle and two torsional spring pressing pins is adopted in the method. The assembling method comprises steps of: mounting a starting gear assembly, a hinge pin, a bushing, a torsional spring and a backswing starting shaft combination and the like on a left crankshaft box cover; then pressing the torsional spring by the assembling assistive device to assemble the backswing starting shaft combination with the starting gear combination in an engaging way; and finally mounting a gasket and a check ring, so as to accomplish the assembling of the whole backswing starting mechanism. According to the assembling method, the special assembling assistive device is designed for providing assistance in mounting, so that the torsional spring can be easier and safer to be compressed and reversed, the force is convenient to exert, and the balance in force exerting can be ensured, and the backswing starting shaft combination and the starting gear combination are convenient to be kept in the initial engaging state; and through the assembling method, the torsional spring is prevented from rebounding to injure people during be mounting, the mounting can be conveniently and quickly carried out with less force, the safety of the torsional spring in mounting is ensured, and the production efficiency is increased.

Description

technical field [0001] The invention relates to a motorcycle recoil starter mechanism, in particular to an assembly method of the motorcycle recoil starter mechanism. [0002] Background technique [0003] The starting systems of existing various motorcycles are divided into two categories of electric starting systems and kick starting systems. Most of the electric starting systems and all kick starting systems all adopt mechanical starting mechanisms. The mechanical starting mechanism is divided into recoil type and overrunning clutch type and so on. In our country, the mechanical recoil starter mechanism is the most common. [0004] Existing a kind of recoil starting mechanism of motorcycle, its mechanism is as follows Figure 1-6 As shown, it includes a torsion spring 4, a recoil starting shaft combination 5, a bushing 3 and a starting gear combination 7; wherein, the bushing 3 is installed in the starting shaft mounting hole on the left crankcase cover 8, and the recoi...

AI Technical Summary

Problems solved by technology

[0005] This existing motorcycle recoil starter mechanism, when assembling, in order to make the recoil starter shaft combination 5 and the starter gear combination 7 in the meshing state, the torsion spring 4 will be compressed in the axial direction and the circumferential direction at the same time, so that the assembled It is very difficult to disassemble and assemble directly because it is difficult to apply force and maintain balance, and the torsion spring 4 in the compressed state is easy to bounce back and hurt people, resulting in accidents.
