A reverse lock structure

Abstract

The invention relates to a reverse gear lock structure. The reverse gear lock structure comprises a guide head, a reverse gear lock torsion spring, a reverse gear lock piece, a reverse gear base, a reverse gear lock bolt, a reverse gear lock spring and a cylinder pin, wherein the guide head, the reverse gear lock torsion spring and the reverse gear lock piece are inserted on a gear shifting shaft; one end of the reverse gear lock torsion spring is hooked on the guide head, and the other end is hooked on the reverse gear lock piece; the reverse gear lock piece comprises a circular lock piece body; an upper stopper, a middle stopper and a lower stopper are radially arranged at the outer periphery of the lock piece body; and the cylinder pin and the lower stopper are movably separated or butted. Through the structure of the reverse gear lock piece, the structure of the guide head, the structure of the cylinder pin and the design of connecting relation, the reverse gear lock structure effectively prevents the damage of a transmission caused by accidental gear engagement, guarantees the engagement of reverse gear from neutral gear, and improves the vehicle safety.

Description

technical field [0001] The invention belongs to the technical field of gearbox control, in particular to a reverse gear lock structure. Background technique [0002] During the driving process, the vehicle must adapt to different road conditions by constantly changing gears to ensure that the vehicle is running in a better state. The gears of the vehicle include forward gear, neutral gear and reverse gear, and the switching of these gears is performed by the same shift handle. When the vehicle is moving forward, the neutral gear and the forward gear can be switched freely, but the reverse gear cannot be switched at will, because after switching the reverse gear, the rotation direction of the gearbox output shaft will change. If the vehicle suddenly changes the direction of rotation, it will have a greater impact on the gears and damage the gears and gearboxes. Since there is only one shift handle, it is easy to mistakenly engage reverse gear during the shift process, resul...

AI Technical Summary

Problems solved by technology

The structure of the shift handle with reverse gear lock is complicated. Usually, the manufacturing and processing of the gearbox is much more difficult than that of the shift handle. Therefore, one gearbox can be used for a variety of vehicles, and the shift handle usually changes with the model. The lock structure will also change and need to be redesigned, causing unnecessary waste
