The invention provides an outer rotor direct drive hub motor low-floor wide-channel drive axle which comprises a main body structure assembly, the main body structure assembly comprises an installation connecting frame, bearing arms and supports, the supports are symmetrically installed on the left side and the right side of the installation connecting frame, and the four corners of each support are each fixedly provided with one bearing arm. A suspension unit and a damping unit are fixedly mounted at the end part of the bearing arm; a multi-phase hub motor unit and a braking unit for achieving braking through a set of U-shaped parallel connecting rods are sequentially and fixedly installed on the outer side of each support, a stabilizer bar unit, an upper guiding thrust rod, a cooling loop and an electric unit are further installed on the supports, and a lower guiding thrust rod is fixedly installed at the front end of the installation connecting frame. According to the low-floor wide-channel drive axle of the outer rotor direct-drive hub motor, the peak torque of the drive axle can be greatly improved, noise and vibration of the wheel end are reduced, the floor height of the drive axle is reduced, the width of a middle channel is increased, and various properties of the drive axle are improved to the maximum extent.

    本发明提供了一种外转子直驱轮毂电机低地板宽通道驱动桥,包括主体结构总成,主体结构总成包括安装连接框架、承载臂和支架,安装连接框架左右两侧对称安装支架,支架的四个角处分别固定安装一个承载臂,承载臂的端部固定安装悬架单元和减震单元;每个支架的外侧依次固定安装多相轮毂电机单元、以一组U型平行连杆实现制动的制动单元,支架上还安装了稳定杆单元、上导向推力杆、冷却回路及电气单元,安装连接框架的前端固定安装了下导向推力杆。本发明所述的外转子直驱轮毂电机低地板宽通道驱动桥,可以大幅提高驱动桥的峰值扭矩,降低轮端的噪声和振动,降低驱动桥的地板高度,增加中间通道的宽度,最大限度的提高驱动桥的各项性能。
