Problems solved by technology

[0002] At present, the vehicle drive system usually uses the internal combustion engine to transmit power to the wheels through the gearbox and the transfer device, but the traditional transfer device is prone to sideslip when turning or passing through complex road sections. In addition, the space required for turning is relatively small. Large; the driving force of the wheels cannot be controlled individually; the hydraulic motor speed of the prior art is low

Abstract

The invention provides a shaft end motor of an automobile electric control hydraulic independent shaft end driving system, aiming at solving the problems that the rotating speed and the output torque of a hydraulic motor are coordinated and matched and intelligently controlled by computer chips. The shaft end motor comprises a hydraulic oil cylinder, a host computer, an encoding disc and a sensor rest. The shaft end motor is mainly characterized in that a plurality of piston connecting rods and slide blocks of the hydraulic oil cylinder move around a rotor in a coordination manner; the straight reciprocating motion of the piston connecting rods and the slide blocks is converted into the circular motion through wave-shaped grooves arranged at the side plane of the rotor; the hydraulic oil cylinder is divided into A-phase, B-phase and C-phase which are arranged circularly; and the encoding disc connected with the rotor shaft end together and the sensor on the sensor rest transmit the position and the operation state information of the rotor to the computer chips to implement intelligent control.

Description

technical field [0001] The invention belongs to the technical field of automobile drive systems, and in particular relates to an axle end motor of an automobile electronically controlled hydraulic independent axle end drive system. Background technique [0002] At present, the vehicle drive system usually uses the internal combustion engine to transmit power to the wheels through the gearbox and the transfer device, but the traditional transfer device is prone to sideslip when turning or passing through complex road sections. In addition, the space required for turning is relatively small. The driving force of the wheels cannot be controlled separately; the hydraulic motor speed of the prior art is relatively low. Contents of the invention [0003] The purpose of the present invention is to solve the problems existing in the prior art, and to provide an axle end motor of an automobile electronically controlled hydraulic independent axle end drive system that can be indepen...
