The invention provides a vehicle, a driving system thereof, and a vehicle driving wheel. The vehicle comprises a frame and a driving system. The driving system comprises the vehicle driving wheel anda driving motor used for driving the vehicle driving wheel to rotate. The vehicle driving wheel comprises a vehicle hub. An inner gear ring is integrally machined on the wall of an inner hole of the vehicle hub, a planet wheel, a planet carrier and a sun wheel which are matched with the inner gear ring are arranged in the inner hole of the vehicle hub, the sun wheel is provided with a connecting end in transmission connection with the driving motor, and the inner gear ring, the planet wheel, the planet carrier and the sun wheel form a planet gear train. By means of the structural advantages ofthe planetary gear train, the large transmission ratio and the large output torque are achieved; and the planetary gear train is arranged in the hub, so the space in the hub is fully utilized, and the space outside the hub is saved, thereby the problem that due to the fact that the transmission ratio and the output torque are increased, the structure is too large, and the installation space is insufficient is solved.
本发明提供了一种车辆及其驱动系统和车辆驱动轮,车辆包括车架和驱动系统,驱动系统包括车辆驱动轮和用于驱动车辆驱动轮转动的驱动电机,车辆驱动轮包括车辆轮毂,所述车辆轮毂的内孔壁上一体加工有内齿圈,车辆轮毂的内孔中设置有与所述内齿圈配套的行星轮、行星架和太阳轮,太阳轮上具有与驱动电机传动连接的连接端,所述内齿圈、行星轮、行星架和太阳轮构成行星齿轮系。本发明的有益效果在于:利用行星齿轮系的结构优势,实现较大的传动比和输出扭矩,并且行星齿轮系设置在轮毂内,充分利用了轮毂内的空间,将轮毂外的空间节约出来,从而解决了由于提高传动比和输出扭矩导致结构过大而引起的安装空间不足的问题。
