Problems solved by technology

[0004] Because the differential adopts the motor as the driving unit, the motor pushes the coupling sleeve forcibly and has a continuous thrust, and the coupling sleeve and the differential case are forcibly engaged, resulting in instant vibration, which affects the stability of the vehicle and assists the motor. The operation drives the shifting fork to move in translation, and the shifting fork moves the sliding sleeve of the coupling shaft to move towards the left half shaft gear. When moving, the sliding sleeve of the coupling shaft is not uniformly stressed, and it is easy to get stuck on the transfer coupling, and the lock is invalid.

Abstract

The invention provides an electronic differential rear axle of an all-terrain vehicle, belongs to the technical field of machinery, and solves the problem that the conventional rear axle cannot realize self-locking. The electronic differential rear axle of the all-terrain vehicle comprises a rear axle box body, a rear axle box cover buckled with the right side of the rear axle box body and an input gear shaft arranged in the rear axle box body in a penetrating manner, wherein a differential housing is arranged in the rear axle box body; a left half-axle gear, an end-toothed half-axle gear and a planetary gear are arranged in the differential housing; a major-arc gear buckled with the right side of the differential housing is arranged in the rear axle box body; the major-arc gear is in transmission connection with the input gear shaft; a movable end-toothed disc, which is coaxial with the end-toothed half-axle gear, is fixedly connected to the major-arc gear in the circumferential direction; the end teeth I of the movable end-toothed disc is matched with the end teeth II of the end-toothed half-axle gear; a pushing structure for pushing the movable end-toothed disc to move axially to the end-toothed half-axle gear is arranged in the rear axle box cover; a reset piece is arranged between the end-toothed half-axle gear and the movable end-toothed disc.

Description

technical field [0001] The invention belongs to the technical field of machinery, and relates to an all-terrain vehicle rear axle, in particular to an all-terrain vehicle electronic differential rear axle. Background technique [0002] The differential is a device with power transmission and power distribution functions. Its function is to automatically adjust the speed of the inner and outer wheels when the vehicle encounters a turn during driving, so as to ensure that the outer wheels will not be dragged on the road. Avoid increased tire wear, thereby ensuring the safety factor of driving vehicles and improving the operating life of the reducer. Existing differentials will slip due to insufficient adhesion when encountering extremely bad road conditions, such as when a certain bridge of a beach car or farmer's car encounters muddy and very bad road surfaces. [0003] In order to prevent the occurrence of slippage, the Chinese patent discloses a differential with a motor-a...
