The invention discloses a drive axle and a vehicle with the drive axle. The drive axle comprises a drive assembly; the driving assembly is fixed to the axle housing assembly, a first hub assembly is arranged at one end of the axle housing assembly, and a second hub assembly is arranged at the other end of the axle housing assembly; the driving assembly is used for driving the first output half shaft to rotate, and the first output half shaft is suitable for driving the first hub assembly to rotate when rotating; the driving assembly is further used for driving the through shaft to rotate; and the second output half shaft is located at the end, close to the second hub assembly, of the through shaft, the second output half shaft is in transmission connection with the through shaft, and the second output half shaft is suitable for driving the second hub assembly to rotate when rotating. According to the drive axle, by additionally arranging the through shaft, the length of the first output half shaft and the length of the second output half shaft are short, and therefore the manufacturing and machining difficulty of the output half shafts can be reduced, meanwhile, torque fluctuation in the transmission process can be reduced, and it is guaranteed that the NVH performance is good.
本发明公开了一种驱动桥及具有该驱动桥的车辆。该驱动桥包括:驱动总成;桥壳总成,驱动总成固定于桥壳总成,桥壳总成的一端设置有第一轮毂总成,桥壳总成的另一端设置有第二轮毂总成;第一输出半轴,驱动总成用于驱动第一输出半轴转动,第一输出半轴转动时适于带动第一轮毂总成转动;贯通轴,驱动总成还用于驱动贯通轴转动;第二输出半轴,第二输出半轴位于贯通轴的靠近第二轮毂总成的一端,且第二输出半轴与贯通轴传动相连,第二输出半轴转动时适于带动第二轮毂总成转动。根据本发明的驱动桥,通过增设贯通轴,使得第一、第二输出半轴的长度较短,从而可以降低输出半轴的制造加工难度,同时还可以减小传动过程中的扭矩波动,保证NVH性能较好。
