Electronic control multi-plate-type self-locking drive axle

Abstract

The invention discloses an electronic control multi-plate-type self-locking drive axle. The electronic control multi-plate-type self-locking drive axle comprises a drive axle box with a first differential shell body and a drive axle box cover. The first differential shell body is internally provided with a left half axle gear, a right half axle gear, a planet gear and a transmitting gear. The drive axle box is internally provided with an input gear meshed with the transmitting gear. The right half axle gear is provided with a second differential shell body rotationally connected with the drive axle box cover and provided with a differential shell cover in a sealed manner. A work friction set is arranged between the right half axle gear and the second differential shell body, and a plane spherical-surface cam set abuts against the right end of the work friction set. A control friction set is arranged between the plane spherical-surface cam set and the second differential shell body. A pushing disc with a plurality of pushing rods and reset springs abuts against the right end of the differential shell cover, the pushing rods leftwards penetrate the differential shell cover and to be matched with the control friction set in an abutting manner, and the reset springs are arranged between the differential shell cover and the pushing disc. A plane cam set abuts against the right end of the pushing disc, and a driving mechanism for allowing the plane cam set to rotate in the circumferential direction is arranged at the outer end of the plane cam set. By means of the electronic control multi-plate-type self-locking drive axle of the structure, the sliding limiting effect is good, and the defect that locking can not be achieved easily during high-speed slipping is overcome.

Description

technical field [0001] The invention relates to the field of mechanical technology, in particular to an electronically controlled multi-chip self-locking drive axle. Background technique [0002] Inside the drive axle of the vehicle, the differential, as a device with power transmission and power distribution functions, can automatically adjust the speed of the inner and outer wheels during the turning process of the vehicle, so as to ensure that the outer wheels will not drag on the road and avoid tire damage. The wear and tear is intensified, so as to ensure the safety factor of the driving vehicle and improve the operating life of the reducer. Ordinary differentials will seriously affect the passing ability when encountering extremely bad road conditions. For example, when the drive axle of a beach car or a farmer's car encounters muddy and very bad roads, the adhesion between the wheels on the muddy road and the road surface is small, and the road surface can only act o...

Ordinary differentials will seriously affect the passing ability when encountering extremely bad road conditions

For example, when the drive axle of a beach car or a farmer's car encounters muddy and very bad roads, the adhesion between the wheels on the muddy road and the road surface is small, and the road surface can only act on the axle shaft with a small reaction moment through the wheels. , so the torque distributed to this wheel by the differential is also small. Although the adhesion between the other driving wheel and the good road surface is relatively large, due to the characteristics of evenly distributed torque, this driving wheel can only be distributed to The same amount of torque as the slipping drive wheels, so that the driving force is no
