Motorcycle shift shaft structure

Abstract

The invention discloses a shifting shaft structure of a motorcycle. The shifting shaft structure comprises a shifting shaft, wherein the shifting shaft is provided with two check rings in an interval mode; the shifting shaft is provided with two flat gaskets at the inner sides of the two check rings; a torsional spring is arranged between the two flat gaskets; the shifting shaft is welded with a fixed plectrum plate; the fixed plectrum plate is provided with a movable plectrum plate; an end of the movable plectrum plate, which is far from the shifting shaft, is provided with a bayonet which can be combined with a variable speed drum; the movable plectrum plate is fit with the fixed plectrum plate through two banking pins which are arranged in an interval mode; the size of a through hole of the movable plectrum plate for containing the two banking pins along the radial direction of the shifting shaft is larger than the diameter of the body of each banking pin; the fixed plectrum plate is integrally provided with a convex plate along one side of the torsional spring; two extending ends of the torsional spring are abutted to two sides of the convex plate; the shifting shaft is wound with an elastic metal wire between the first check ring and the first flat gasket; and a free end of the elastic metal wire penetrates out of holes of the fixed plectrum plate and the movable plectrum plate after penetrating through the movable plectrum plate and the fixed plectrum plate from the outer side. The shifting shaft structure is simple and is flexible in shifting.

Description

technical field [0001] The invention relates to a shift shaft structure of a motorcycle engine. Background technique [0002] In the prior art, the shift shaft of the motorcycle is provided with a return spring and a shift arm, and the shift shaft is rotated by stepping on the pedal, and then the shift arm is driven to turn the shift drum to rotate, thereby realizing shifting. During the process of the gear shifting arm turning the gear shifting drum, the gear shifting arm will perform telescopic movement in the direction of the gear shifting shaft. After the gear shift is completed, the gear shift shaft returns through the return spring, but the gear shift arm may return slowly, thus causing inflexible gear shifting. [0003] Therefore, those skilled in the art are devoting themselves to developing a shift shaft structure with more flexible shifting. Contents of the invention [0004] In view of the above-mentioned defects in the prior art, the technical problem to be s...
