Self-adapted traction control drive axle differential mechanism

Abstract

The invention relates to a self-adapted traction control drive axle differential mechanism. The differential mechanism is composed of a main reduction differential mechanism, a right drive torsion adjusting device and a left drive torsion adjusting device, wherein the right drive torsion adjusting device and the left drive torsion adjusting device are symmetrically arranged, are fixed on a differential mechanism shell of the main reduction differential mechanism, and have the same structure and same acting performance; and each of the right drive torsion adjusting device and the left driven torsion adjusting device comprises a torsion adjusting driving gear, a torsion adjusting driven gear, a hollow shaft, an air cylinder and a clutching mechanism. The differential mechanism has no inner speed difference interference, has high driving efficiency and saves fuel oil; torques needed by attaching conditions of all wheels can be automatically adjusted to drive an automobile to move, and the driving force of each wheel can reach the optimal state; The fundamental difference between the differential mechanism provided by the invention and an existing regular locking differential mechanism is that a bidirectional clutch is arranged and is normally engaged to control the torsion performance; and the differential mechanism is pneumatically reversed in a process of baking up. Therefore, the power utilization rate and the all-terrain and all-weather working conditions are greatly improved, and the self-adapted control capability can be 100% so that the differential mechanism can be used for large and small vehicles.

Description

technical field [0001] The invention belongs to the technical field of wheeled vehicle transmission, and relates to a differential, in particular to an adaptive traction control drive axle differential, which is especially suitable for truck drive axles and engineering vehicle drive axles. Background technique [0002] Wheel slippage will occur during driving of wheeled vehicles, which will affect driving safety and stability. And the vehicle skids, nothing more than because one end of the driving wheel driving force is too large so that the rotating speed is zero, and the driving force at the other end is relatively small and the rotating speed is 2 times the output rotating speed, resulting in the slipping vehicle cannot walk. Therefore, in order to realize the control of vehicle slippage, it is necessary to control the rotational speed of either end of the drive wheel to be non-zero. At present, there are two ways to control vehicle skid: electronic control and mechanica...

Its technology can only be used on newly designed vehicles of 4×4, 6×6, 6×4, and 8×8. It cannot be reproduced on other vehicles, and cannot be applied to 4×2 vehicles. It is difficult to promote

[0006] Therefore, it is necessary to develop a drive axle differential device that can effectively distribute engine power to solve the problem of torque intermodulation and anti-skid for truck drive axles and engineering vehicle drive axles.
