The invention provides a drive axle, a drive assembly and a vehicle, the drive axle comprises a power device and a reduction gear, the power device comprises a drive shaft, the reduction gear comprises a primary transmission shaft and a secondary transmission shaft, the drive shaft is in transmission connection with the primary transmission shaft, and the primary transmission shaft is in transmission connection with the secondary transmission shaft. Power output by the driving shaft is output to the driving wheel after secondary speed reduction and torque increase, and the overall speed reduction ratio is increased. Wherein the driving shaft and the first-stage transmission shaft are arranged in parallel and at intervals, the first-stage transmission shaft and the second-stage transmission shaft are arranged in parallel and at intervals, and a staggered arrangement structure is formed between the first-stage transmission shaft and the second-stage transmission shaft, so that the internal structures of the power device and the speed reduction device are more compact; the installation space of the power device and the speed reduction device in the length direction and the width direction of the vehicle body can be reduced, so that the space occupied by the drive axle in the whole vehicle is reduced, meanwhile, the front overhang or the rear overhang of the vehicle is reduced, the layout difficulty of the vehicle is lowered, and optimization and improvement of the vehicle are facilitated.
本发明提供了一种驱动桥、驱动总成及车辆,驱动桥包括动力装置和减速装置,动力装置包括驱动轴,减速装置包括一级传动轴和二级传动轴,驱动轴与一级传动轴传动连接,一级传动轴与二级传动轴传动连接,驱动轴输出的动力经过二级减速增矩后输出至驱动轮,提高了整体减速比。其中,驱动轴与一级传动轴相互平行且间隔设置,一级传动轴与二级传动轴相互平行且间隔设置,相互之间形成错位式的排布结构,使得动力装置和减速装置的内部结构更为紧凑,可以减小动力装置和减速装置沿车身长度方向和宽度方向上的安装空间,从而减小驱动桥占用整车的空间,同时有助于减小车辆的前悬距或后悬距,降低车辆的布局难度,便于车辆进行优化改进。
