The invention discloses a vehicle electric wheel and an electric vehicle. The vehicle electric wheel comprises a motor and a speed reducer, and also comprises a main shaft and a supporting disc; the main shaft is used for driving a hub, and the motor is connected with the main shaft through the speed reducer; the supporting disc is provided with a suspension side and a hub side which are oppositeto each other, and the suspension side of the supporting disc is used for connecting a suspension and fixing the motor and the speed reducer; the main shaft penetrates through and is rotationally connected with the supporting disc. By changing the suspension mounting position and arranging the suspension mounting position on one side of a hub bearing, the distance between the mounting and fixingposition of an unsprung mass on the wheel and the hub bearing is short, a cantilever beam structure of the unsprung mass is avoided, and the operation stability, smoothness and trafficability of the vehicle are improved.
本发明公开一种车用电动轮及电动车,包括电机和减速器;还包括主轴和支撑盘;所述主轴用于驱动轮毂,所述电机通过所述减速器连接所述主轴;所述支撑盘具有相对的悬架侧和轮毂侧,所述支撑盘的悬架侧用于连接悬架和固定所述电机和所述减速器;所述主轴贯穿并转动连接所述支撑盘。本发明通过改变悬架安装位置,将悬架安装位置布置在轮毂轴承一侧,使得簧下质量在车轮上的安装固定位置与轮毂轴承的距离短,避免簧下质量的悬臂梁结构,提高了车辆的操纵稳定性、平顺性与通过性。
