Problems solved by technology

[0002] Existing new energy motor vehicles still have the problems of poor driving feeling and high energy consumption when the driving state changes greatly and quickly, such as starting and re-accelerating, resulting in their ride experience and cruising range unable to meet people's normal needs. At the same time, the power device used in the driving device of a general new energy motor vehicle switches between different speed ratios through more shafts and gears. The mechanism is large in size and heavy in weight, which is not conducive to the weight control and space layout of the motor vehicle.

Abstract

A driving device for new energy motor vehicles includes a transmission mechanism disposed between an actuator and an output device. The actuator includes a power source, the power source is connectedwith an input shaft in a coupling mode. The transmission mechanism includes the input shaft, and a first transmission shaft and a second transmission shaft both arranged in the circumferential direction of the input shaft in a planet mode. The output device includes a main deceleration output gear and a differential mechanism coupled to each other. Through the different speed ratios formed by twodifferent tooth ratios including the tooth ratio of a first driving gear and a first transmission gear and the tooth ratio of a second driving gear and a second transmission gear, the switching of transmission states can be achieved. The actuator also includes a first driving device and a second driving device both connected with the first and second transmission shafts to assist in regulating thestability of power transmission and optimize energy consumption. The driving device for new energy motor vehicles has the advantages of high energy utilization efficiency, large energy density, low energy consumption, compact structure, stable power output, flexible switching, high overall structural strength, and long service life.

Description

technical field [0001] The invention relates to a power transmission device of a motor vehicle, in particular to a driving device for a new energy motor vehicle. Background technique [0002] Existing new energy motor vehicles still have the problems of poor driving feeling and high energy consumption when the driving state changes greatly and quickly, such as starting and re-accelerating, resulting in their ride experience and cruising range unable to meet people's normal needs. At the same time, the power device used in the driving device of general new energy motor vehicles switches between different speed ratios through more shafts and gears. The mechanism is large in size and heavy in weight, which is not conducive to the weight control and space layout of the motor vehicle. Contents of the invention [0003] The purpose of the present invention is to provide a drive device for new energy vehicles with high energy utilization efficiency, high energy density, low energ...
