The embodiment of the invention provides a mechanical differential wheel-side electric drive axle and an automobile, and relates to the field of axles. The mechanical differential wheel-side electricdrive axle comprises an axle housing, a first motor, a first planetary reducer, a second motor, a second planetary reducer and a differential assembly; the first motor is in transmission connection with the first planetary reducer, the first planetary reducer is in transmission connection with one end of the differential assembly, and the first planetary reducer is used for being in transmission connection with a first wheel side; the second motor is in transmission connection with the second planetary reducer, the second planetary reducer is in transmission connection with the other end of the differential assembly, and the second planetary reducer is used for being in transmission connection with a second wheel side; and the differential assembly is fixed on the axle housing. According to the embodiment of the invention, dual-motor distributed driving is adopted, and whole vehicle space arrangement is facilitated; and meanwhile, more reliable and low-cost axle design is realized by utilizing mechanical differential.
Description
technical field [0001] The invention relates to the field of vehicle axles, in particular to a mechanical differential wheel side electric drive axle and an automobile. Background technique [0002] The axle is a key part of the car, used to bear the load of the car and maintain the normal driving of the car on the road. In the prior art, the vehicle axle adopts an electronic differential, that is, the differential speed when the drive axle turns is realized by electronic components. However, electronic components have reliability problems and high cost, which cannot meet the requirements of high quality, high reliability and low cost. Contents of the invention [0003] The object of the present invention is to provide a mechanical differential wheel-side electric drive axle and an automobile, which adopts dual-motor distributed drive, which is beneficial to the space layout of the vehicle; at the same time, the mechanical differential speed is used to realize a more reli...
