The invention discloses a rear drive device for an electric vehicle based on a three-phase outer rotor double salient pole permanent magnet motor. It includes a three-phase outer rotor double-salient pole permanent magnet motor composed of a central stator shaft and an outer rotor. The front end of the outer rotor is fixedly connected to the hub of the vehicle through a flange. There is a braking mechanism, the rear end of the stator shaft is fixedly installed on the rear suspension, the rear suspension is connected to the lower end of an axle-bridge connector, and the upper end of the axle-bridge connector is connected to the side beam of the vehicle. It has the following beneficial effects: realize direct speed control of the motor, improve the control accuracy of the motor speed; reduce the weight of the vehicle, reduce the cost of vehicle manufacturing and later maintenance costs; The design cost and material cost of the car; its structural design is reasonable, and the manufacturing cost and process cost are low, which is conducive to improving the vehicle performance of the electric car.
Description
technical field [0001] The invention relates to a rear drive device for an electric vehicle, in particular to a rear drive device for an electric vehicle based on a three-phase outer rotor double salient pole permanent magnet motor, and belongs to the technical field of new energy vehicle manufacturing. Background technique [0002] In terms of the drive type of new energy vehicles, most manufacturers basically use the inherent vehicle technology platform for refitting and design, and use electric motors or synchronous motors to realize centralized drive on the front axle of the vehicle through transmission and transmission mechanisms. This type of driving fails to give full play to the various technical advantages of motor driving, so that it is difficult to make a breakthrough in improving the cost performance. In terms of vehicle performance, it shows that the unsprung mass of the car has been increased, resulting in reduced vehicle stability and increased vibration; in o...
