Abstract

The invention discloses a torque directional distribution electric drive axle using planet rows and duplicate gears. The torque directional distribution electric drive axle comprises a main motor, an auxiliary motor, a bevel gear differential mechanism, a left half shaft, a right half shaft, a first planet row, a second planet row, a duplicate gear mechanism, a first clutch, a second clutch and the like. The main motor and the auxiliary motor are respectively connected with the input ends of the first planet row and the second planet row; the output ends of the first planet row and the second planet row are respectively connected with A differential shell and the input end of the duplicate gear mechanism; the output end of the duplicate gear mechanism is connected with the differential mechanism shell. The first clutch is used for fixing the second planet carrier or self-locking the second planet row; and the second clutch is used for connecting the second planet carrier or the second sun gear with the left half shaft. By controlling the first clutch and the second clutch, three driving modes of main motor independent driving, dual-motor torque coupling driving and torque directional distribution can be realized.

Description

technical field [0001] The invention belongs to the field of electric vehicle transmission, and in particular relates to a highly integrated torque-directed distribution electric drive axle using planetary rows and dual gears. Background technique [0002] In recent years, with the development and progress of society, electric vehicles featuring zero fuel consumption, high integration, fast power response, and high driving performance have been vigorously developed and gradually recognized by the market. With the development and popularization of the market, electric vehicles will also develop in the direction of high-end, high-performance, and diverse personalization in the future. Therefore, the demand for advanced drive technologies that can improve chassis performance is increasing. Electric torque vectoring technology is one of them. [0003] Torque directional distribution (TV) technology is an advanced drive technology that randomly distributes the driving torque gen...
