Clutch control type electric drive axle

Abstract

A clutch-controlled electric drive axle, which solves the problems of uneven force and large energy loss in the sliding condition of the existing electric drive axle, including the axle housing and the driven motor assembled in the axle housing , reducer assembly, differential assembly, coaxial direct-coupled drive axle assembly composed of left and right driving half shafts and left and right hubs. The technical points are: the hollow shaft of the driving motor is assembled with an intermediate drive The spline at one end of the intermediate drive shaft is meshed with the half shaft gear of the differential assembly, and a clutch is set between the spline at the other end of the intermediate drive shaft and the spline at the end of the right drive half shaft, and the clutch reciprocates along the axis Move to realize the mutual engagement or separation of the intermediate drive shaft and the right drive half shaft. In addition to maintaining the compact structure of the coaxial direct-coupled drive axle, the design is reasonable, and meets the requirements of matching various electric vehicle chassis, it also has the characteristics of automatic clutching and closing, significant energy saving, and is conducive to improving the cruising range of the car. .

Description

[0001] Technical field: [0002] The invention relates to a drive device for electric vehicles, in particular to a clutch-controlled electric drive axle that integrates a motor, a reducer and a differential reducer, and enables the input and output to have a clutch function. It is suitable for matching different types of electric car. [0003] technical background: [0004] At present, the structure of common drive axles for electric vehicles is mainly divided into two types, one is to connect the drive motor outside the traditional drive axle, and the motor is arranged in parallel with the axle; the other is to connect the drive motor outside the traditional drive axle , the motor and the axle are arranged vertically. The above two arrangements usually adopt the form of single motor and double drive, and the three axes of input, output shaft and differential are arranged vertically or in parallel. These two arrangements will cause a certain deviation between the center of gr...
