Abstract

The invention provides a double-power coupling driving assembly adopting a dual-motor rotating speed and torque coupling driving mode, which can realize the powerless interruption toromatic and stepless transmission of a transmission system in a large range. In the invention, a fixed axes gear and a planetary gear are adopted as a rotating speed and torque coupling device of an auxiliary motor and a main driving motor. The auxiliary motor (5) and the main driving motor (9) are arranged at the same side of a power coupling device and arranged in axial parallel; power output by the main driving motor (9) and the auxiliary motor (5) is coupled by the coupling device and input to a driving wheel (18) to drive a vehicle to run.

Description

technical field [0001] The invention belongs to the technical field of power assembly components, and in particular relates to a dual-motor power coupling drive assembly. Background technique [0002] Compared with traditional mechanical transmission, electric transmission has many advantages, such as continuously variable speed, flexible layout, improved acceleration performance, braking performance, steering performance, climbing performance, etc. Due to the limitations of the existing motor and electronic technology, the traditional electric transmission system usually uses a transmission between the motor and the driving wheel to meet the needs of high torque and high speed during vehicle driving, and the power loss in the transmission is large, and there is power interruption. , the control mode is single and so on. Contents of the invention [0003] The purpose of the present invention is to provide a dual-motor speed and torque coupling drive assembly suitable for ...
