Abstract

The invention discloses an electric differential mechanism with a directed torque distribution function. The electric differential mechanism with the directed torque distribution function comprises a main drive mechanism, a bevel gear differential mechanism body, a TV control drive mechanism used for outputting control power, a first single-row planetary gear system, a second single-row planetary gear system and a third single-row planetary gear system, wherein a first sun gear is supported on a first half axle through a bearing, a first gear ring is coaxially and fixedly connected with the first half axle, and a first planetary carrier is connected with the control output end; a second planetary carrier is fixed to a drive axle housing, and a second sun gear is fixedly connected with the first sun gear; the second sun gear is supported on the first half axle through a bearing; a third sun gear is fixedly connected with a differential mechanism shell, a third planetary carrier is fixedly connected with a second inner gear ring, and a third gear ring is fixedly connected with the first half axle; and the second single-row planetary gear system and the first single-row planetary gear system have the same characteristic parameters. By means of the electric differential mechanism with the directed torque distribution function, drive torque of an automobile can be distributed to wheels on the left side and the right side in a directed mode according to control demands 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...
