Abstract

The invention provides a power-driven system and a vehicle. The power-driven system comprises a first front driving motor, a second front driving motor, a rear driving motor, a power supply module and a high-tension distribution box, wherein the first front driving motor and the second front driving motor are connected with two front wheels in one-to-one correspondence; the rear driving motor is connected with a first wheel edge speed reducer and a second wheel edge speed reducer through a differential mechanism; the first wheel edge speed reducer and the second wheel edge speed reducer are connected with two rear wheels in one-to-one correspondence; the power supply module is electrically connected with the high-tension distribution box; the high-tension distribution box is in electric connection with the first front driving motor, the second front driving motor and the rear driving motor. The power-driven system solves the problems that an existing power-driven system cannot meet low-speed small-torque driving requirements and is large in power consumption in low-speed large-torque driving process.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a power drive system and an automobile. Background technique [0002] The existing power drive system generally adopts a mechanical engine as the power output. Due to the characteristics of the engine, it is difficult for the existing drive system to meet the needs of low-speed and low-torque driving in order to prevent slipping when the vehicle is running. Engine is the power drive system of power output, can not satisfy above-mentioned requirement. Moreover, when the vehicle is running at a low speed, multi-stage deceleration is required to increase the driving torque to the range required for overcoming obstacles, and the power consumption is relatively large. Contents of the invention [0003] The invention provides a power drive system and an automobile, which solves the problem that the existing power drive system cannot meet the requirements for low-speed and small...
