4results about How to "Efficient lubrication" patented technology

This utility model belongs to the field of new energy vehicle power transmission technology, and discloses a single-motor two-speed electric drive axle powertrain, including a disc motor, a reducer housing, a first shaft assembly, an intermediate shaft assembly, a reducer end cover, an axle housing, a first half-shaft, a differential, a second-stage reduction passive gear, a second half-shaft, a coupling sleeve, and a differential lock assembly. This solution achieves the advantages of compact structure, short axial dimension, and high power density by adopting an integrated design of an axial flux disc motor and a two-speed reduction mechanism, which is convenient for application in vehicles with high ground clearance requirements and limited installation space. By using a ball screw type shifting actuator in conjunction with motor speed adjustment, synchronizer-free rapid shifting is achieved, improving shifting smoothness and system reliability. The hollow intermediate shaft assembly and lubrication oil passage design make lubrication efficient and the structure simplified, improving operational reliability. The rear-mounted integrated differential lock assembly enhances the ability to get out of trouble in complex road conditions and the vehicle's adaptability.
