Torsional spring dismounting auxiliary tool

Abstract

The invention discloses a torsional spring dismounting auxiliary tool which is characterized by comprising a connecting plate, a handle and a connecting rod. The connecting plate is an arc-shaped plate. The connecting rod is vertically fixed on a middle position of the connecting plate. The handle is in a long-bar shape. The middle of the handle is vertically fixed on an end portion of one end of the connecting rod, and the end of the connecting rod is far away from the connecting plate. Two torsional spring pressing pins are vertically fixed at two ends of the connecting plate along a direction which deviates from the connecting rod. The two torsional spring pressing pins are symmetrically arranged, and limit pillar holes are formed in the bottom of one end of each torsional spring pressing pin in a coaxial mode, and the end of the torsional spring pressing pin is far away from the connecting rod. A corresponding positional relation of the connecting rod and the two torsional spring pressing pins matches with a positional relation of a position where is symmetrical to a side edge of a fan-shaped gear which is provided with a starting shaft of a motorbike backswing start mechanism and a torsional spring limited post and another side edge of the fan-shaped gear. The torsional spring dismounting auxiliary tool enables the assembling of the torsion spring of the motorbike backswing start mechanism to be convenient, rapid, labor-saving and safe.

Description

technical field [0001] The invention relates to a recoil starting mechanism of a motorcycle, in particular to an auxiliary device for disassembling and assembling a torsion spring in the recoil starting mechanism of a motorcycle. [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 s...

Problems solved by technology

[0005] In this existing motorcycle recoil starter mechanism, when the torsion spring is assembled, 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 simultaneously in the axial direction and the circumferential direction, As a result, a large compression elastic force is generated during assembly, and it is often very difficult to disassemble and assemble directly due to reasons such as difficulty in applying force and maintaining balance, and the torsion spring 4 in the compressed state is easy to bounce back and hurt people, resulting in accidents
