The invention provides a coaxial driving device and a vehicle, the coaxial driving device comprises a shell, a stator and a rotor, the shell comprises an end cover, and the end cover is provided with a first overflowing channel; the rotor shaft is internally provided with a cavity, the cavity penetrates through the two ends of the rotor shaft, the rotor shaft is provided with a second hole, and the second hole is communicated with the cavity and the rotor; and the penetrating shaft is arranged in the cavity of the rotor shaft in a penetrating manner, one end of the penetrating shaft extends to the end cover, a second overflowing channel is formed in the penetrating shaft, and a third hole and a fourth hole which are communicated with the second overflowing channel are formed in the penetrating shaft. After flowing out of the first hole, the cooling medium can be cached in the buffer tank and fills the buffer tank, and the pressure of the cooling medium in the buffer tank is easy to increase. Therefore, under the condition that the penetrating shaft rotates at a high speed and the first hole and the third hole are staggered, the cooling medium can flow into the third hole, and the cooling effect on the rotor is guaranteed.

    本发明提供了一种同轴驱动装置及车辆,其中,同轴驱动装置包括:壳体、定子和转子,壳体包括端盖,端盖上设置有第一过流通道;转子轴,转子轴内部具有腔体,腔体贯通转子轴的两端,转子轴上设置有第二孔,第二孔与腔体以及转子处连通;贯穿轴,穿设在转子轴的腔体内,并且贯穿轴的一端延伸至端盖处,贯穿轴内设置有第二过流通道,贯穿轴上设置有与第二过流通道连通的第三孔和第四孔。冷却介质从第一孔流出后,可以先在缓冲槽内进行缓存并充满缓冲槽,冷却介质在缓冲槽内容易提高压力。因此在贯穿轴高速旋转且第一孔和第三孔错位的情况下,冷却介质也能够流入至第三孔内,保证对转子的冷却效果。
