The invention relates to the technical field of automobile transmission. The embodiment of the invention provides a vehicle and a drive axle thereof. According to the vehicle and the drive axle thereof, the drive axle at least comprises the first-stage parallel shaft type speed reduction assembly, the two second-stage planetary speed reduction assemblies and the differential assembly, the first-stage parallel shaft type speed reduction assembly and the two second-stage planetary speed reduction assemblies are arranged, and the differential assembly is located between the first-stage parallel shaft type speed reduction assembly and the second-stage planetary speed reduction assemblies; the differential assembly can be integrated with the first-stage parallel shaft type speed reduction assembly, and the torque borne by the differential assembly is smaller than that borne by the mode that the differential assembly is arranged behind the second-stage speed reducer. Therefore, the reliability of the whole structure is improved.

    本申请涉及汽车传动技术领域,本申请实施例提供了一种车辆及其驱动桥。上述车辆及其驱动桥中,驱动桥至少包括一级平行轴式减速总成、两个二级行星减速总成以及差速总成,通过设置一级平行轴式减速总成和两个二级行星减速总成,并将差速总成位于一级平行轴式减速总成和二级行星减速总成之间,使得差速总成可以和一级平行轴式减速总成集成在一起,差速总成所承受的扭矩较在二级减速器后设置差速总成的方式相比更小。由此,提高了整体结构的可靠性。
