Electromagnetic thrust self-locking rear axle

Abstract

The invention provides an electromagnetic thrust self-locking rear axle, and belongs to the technical field of machines. The rear axle solves the problem that an existing rear axle slips and can not achieve self-locking. The electromagnetic thrust self-locking rear axle comprises a rear axle box and a rear axle box cover buckled to the right side of the rear axle box. A differential shell is arranged in the rear axle box cover, a left half shaft gear, an end tooth half shaft gear and a planetary gear are arranged in the differential shell, the left end of the differential shell is fixedly connected with a transmission gear coaxial with the end tooth half shaft gear, an input gear shaft perpendicular to the axis of the transmission gear is further arranged in the rear axle box, a driven gear shaft is arranged between the rear axle box and the rear axle box cover in a penetrating mode and is arranged parallel to the axis of the transmission gear, the left end of the driven gear shaft is provided with a bevel gear meshed with the input gear shaft, the right end of the driven gear shaft is provided with a spur gear meshed with the transmission gear, and the right side of the differential shell is provided with an electromagnetic thrust self-locking structure. The rear axle has the advantages of being good in self-locking effect, capable of effectively improving running performance of a whole vehicle and the like.

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 electromagnetic thrust self-locking rear axle of an all-terrain vehicle. 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 different...

AI Technical Summary

Problems solved by technology

[0004] Because the differential adopts the motor as the drive unit, the motor rigidly pushes the coupling sleeve with continuous thrust, and the coupling sleeve is forced to mesh with the differential case, resulting in instant vibration, which affects the stability of the vehicle. The operation of the motor drives the shift fork to move in translation, and the shift fork moves the sliding sleeve of the coupling shaft to move in the direction of the left half-shaft gear. When moving, the sliding sleeve of the coupling shaft is unevenly stressed, and it is easy to get stuck on the transfer coupling, and the lock is invalid.
