The invention relates to the technical field of vehicle power systems, in particular to a vehicle pure electric hard axle which comprises a cross beam and a hard axle body, a driving part used for outputting power and a guide rail base arranged on the cross beam are arranged on the cross beam, a sliding rail is arranged on the guide rail base, and the hard axle body is arranged on the sliding rail. A sliding rail is arranged on the hard bridge body, a sliding block is connected to the sliding rail in a sliding mode, a first rotating seat and a second rotating seat are arranged on the sliding block, a universal joint is arranged on the hard bridge body, and the transmission rotating shaft sequentially penetrates through the second rotating seat and the first rotating seat and is rotationally connected with the second rotating seat and the first rotating seat. The driving motor is installed on the cross beam, the cross beam bears the weight of the driving motor, therefore, the weight of the driving motor and the weight of the hard bridge body are separated, the unsprung weight is reduced, and meanwhile through cooperation of the speed reducer and the transmission shaft gear, power of the driving motor can be stably transmitted to the hard bridge body.
本发明涉及车辆动力系统技术领域,尤其涉及一种车辆纯电动硬桥,该车辆纯电动硬桥包括横梁以及硬桥主体,所述横梁上设置有用于输出动力的驱动件以及在所述横梁上设置的导轨底座,所述导轨底座上设置有滑轨,所述滑轨上滑动式连接有滑块,所述滑块上设置有第一旋转座和第二旋转座,所述硬桥主体上设置有万向节,所述传动旋转轴依次穿过所述第二旋转座和所述第一旋转座并与所述第二旋转座和所述第一旋转座转动式连接,通过将驱动电机安装在横梁上,使横梁承受驱动电机的重量,由此实现将驱动电机与硬桥主体的重量分离降低簧下重量,同时通过减速器与传动轴齿轮的配合,可实现驱动电机的动力稳定传输到硬桥主体。
