Abstract

The invention discloses a duplex planetary gear train torque directional distribution electric drive axle. The drive axle comprises a main drive motor, a TV control drive motor and a duplex planetarygear train, wherein a power output shaft of the main drive motor is connected with a shell of a bevel gear differential mechanism through a speed reduction mechanism; a first axle shaft is rotationally supported on the shell, penetrates through the shell and is connected with a first axle shaft gear of the bevel gear differential mechanism, and a second axle shaft is rotationally supported on theshell, penetrates through the shell and is connected with a second axle shaft of the bevel gear differential mechanism; and the duplex planetary gear train comprises a first sun gear, a second sun gear, a first end planet gear, a second end planet gear and a first planet carrier. The torque of wheels on the left side and the right side is distributed at will.

Description

technical field [0001] The invention relates to a dual planetary gear train torque directional distribution electric drive axle, which belongs to the technical field of electric vehicle transmission. Background technique [0002] In recent years, with the improvement of people's living standards and the continuous advancement of technology, people have put forward higher and higher requirements for the quality of cars, from the initial demand only as a means of transportation to the safety, comfort, economy, etc. In terms of demand for performance and driving pleasure, people's demand for high-performance vehicles is also increasing year by year. Therefore, investment in research and development of high-performance vehicles is also very necessary. [0003] Electric vehicles are an important development direction for future transportation to adapt to energy conservation and emission reduction. They have received attention from various countries and have achieved good developm...
