Problems solved by technology

However, the differential lock is only used in bad road conditions or extreme conditions, and it will cause serious damage to car components when used in normal driving
It is troublesome to manually lock and unlock according to different road conditions, and it is easy to damage parts if the operation is wrong
Some advanced structures can realize automatic locking and unlocking, but passive frequent locking and unlocking will affect the service life and driving comfort

Abstract

The invention discloses an automobile active differential machine drive axle. The automobile active differential machine drive axle comprises an axle shell, a front fixed plate, a rear fixed plate, a differential machine I and a differential machine II, wherein the front fixed plate is provided with a first connecting hole and a second connecting hole; an auxiliary power output shaft passes through the first connecting hole to extend into an inner cavity of the axle shell, is connected with a driving motor, and is provided with a driving gear I; an inner cavity of the axle shell is provided with a first gear shaft and a second gear shaft; the first gear shaft is provided with a driven gear II which is provided with a driven gear III; the driven gear II and the driven gear III are meshed with the driving gear I; the shell of the first differential machine I is provided with a first gear ring gear; the shell of the second differential machine II is provided with a second gear ring gear; a driving gear IV is meshed with the first gear ring gear; a driving gear V is meshed with the second gear ring gear. According to the invention, the locking and opening states of the automobile differential machine can be achieved; the turning radius can be reduced greatly; the automobile running performance is improved; the automobile active differential machine drive axle can be applied to the fields of vehicles, robots and the like.

Description

technical field [0001] The invention relates to the technical field of automobile steering structures, in particular to an active differential transmission axle for a vehicle. Background technique [0002] The ordinary differential structure in the prior art allows the half shafts on both sides to rotate at different speeds while transmitting power to the half shafts on both sides of the axle, so that the wheels on both sides can run at unequal distances in the form of pure rolling as much as possible, reducing the contact between the tires and the ground. friction. However, in off-road or bad road conditions, due to the equal torque of the differential, the vehicle may get into trouble because any wheel loses adhesion. [0003] The axle with differential lock can lock the differential case and the half shaft together when one drive wheel slips, so that the differential loses its differential effect and transfers the torque to the drive shaft on the other side. be able to ...
