Abstract

The invention discloses an electric differential mechanism with a torque fixed direction allocation function. The electric differential mechanism comprises a main driving mechanism, a bevel gear main differential mechanism, a TV control driving mechanism, a first single row planetary gear system, a second single row planetary gear system and a third single row planetary gear system. The TV control driving mechanism is used for outputting control power; a first sun gear is fixedly coaxially connected to a first axle shaft, and a first gear ring is connected to a control output end; a second gear ring is fixed on a driving axle housing, and a second planetary frame is fixedly connected to the first planetary frame; a second sun gear is rotatably supported on the first axle shaft; a third sun gear is fixedly connected to the second sun gear, a third planetary frame is fixedly connected to a differential housing, and a third gear ring is fixedly connected to the first axle shaft, wherein the second single row planetary gear system has the same characteristic parameter as the first single row planetary gear system. The electric differential mechanism with the torque fixed direction allocation function enables driving torque of a vehicle to be directionally distributed to wheels at the left and right sides according to a control requirement of control logic.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle transmission, and in particular relates to an electric differential with torque orientation distribution function. Background technique [0002] Due to the energy crisis and the increasing emphasis on environmental protection, new energy vehicles are the reverse of the development of future vehicles, and electric vehicles have achieved rapid development worldwide. Compared with traditional internal combustion engine vehicles, electric vehicles are more economical and environmentally friendly, and the characteristics of nearly zero emissions make electric vehicles have significant advantages in environmental protection. At the same time, electric vehicles have better acceleration performance due to the characteristics of fast response of the drive motor, low speed and high torque, and the motor speed and torque are easy to obtain, which can control the electric vehicle more precisely. The...
