Abstract

The invention provides a wheel drive axle which comprises a first wheel drive system. The first wheel drive system comprises a motor and a primary speed reducer which is connected with an output shaft of the motor, wherein the primary speed reducer comprises an input shaft gear, an output shaft gear, an intermediate shaft driven gear and an intermediate shaft drive gear; a rotating shaft of the output shaft gear is coaxial with a wheel rotating shaft; a rotating shaft of the input shaft gear is coaxial with an output shaft of the motor; the output shaft of the motor is fixedly connected with the input shaft gear so as to drive the input shaft gear; the input shaft gear is meshed with the intermediate shaft driven gear so as to drive the intermediate shaft driven gear and the intermediate shaft drive gear which are fixed on the same shaft as the intermediate shaft driven gear; and the intermediate shaft drive gear is meshed with the output shaft gear so as to transfer driving force to the output shaft gear. In the wheel drive axle, the primary speed reducer has simple structure and is easy to process and assemble.

Description

technical field [0001] The invention relates to a wheel side drive axle. Background technique [0002] The power transmission route of a vehicle using an ordinary rear drive axle is the drive motor-(clutch)-transmission-transmission shaft-rear axle main reducer-differential device-half shaft-(wheel-side reducer)-wheels. The power transmission chain is relatively long, and there is a certain amount of energy loss due to gear meshing and shaft transmission. The longer the transmission chain, the greater the energy loss, so the efficiency of the drive system is lower, and the economy of the vehicle is also lower. [0003] In the middle of the ordinary rear drive axle axle housing, the main reducer and differential gear need to be installed, and a raised axle package needs to be added to the axle housing. In addition, for city buses using ordinary rear drive axles, the internal combustion engine (drive motor) and transmission are arranged on the vehicle. The rear end of the fra...
