The invention discloses a driving shaft assembly and a vehicle, and relates to the technical field of vehicle driving shafts, on one hand, the driving shaft comprises a driving shaft, a driving sleeve, a fixed universal joint and a protective sleeve, one end of the driving sleeve is provided with a sliding cavity, and a spline groove is formed in the sliding cavity; a spline in sliding fit with the spline groove is arranged at one end of the driving shaft; the two fixed universal joints are respectively connected to the other ends of the driving shaft and the driving sleeve; the protective sleeve is arranged at the joint of the driving shaft and the driving sleeve in a sleeving mode and can stretch out and draw back in the axis direction. On the other hand, the invention further provides a vehicle which comprises the driving shaft assembly, a wheel and a speed reducer. The driving shaft and the driving sleeve are slidably connected through the spline in the axis direction, the ends, away from mutual connection, of the driving shaft and the driving sleeve are connected with the wheels and the speed reducer through the fixed universal joints, and therefore the length change of the shaft rod caused by wheel jumping is compensated through stretching and retracting of the driving shaft and the driving sleeve; and vibration of the whole vehicle is reduced.

    本发明公开了一种驱动轴总成及车辆,涉及车辆驱动轴技术领域,一方面,该驱动轴包括驱动轴、驱动套、固定式万向节及防护套,驱动套的一端设有滑动腔,滑动腔内设有花键槽;驱动轴的一端设有与花键槽滑动配合的花键;固定式万向节设有两个,分别连接在驱动轴与驱动套的另一端;防护套套设在驱动轴与驱动套的连接处,并可沿轴线方向伸缩。另一方面,还提供一种车辆,包括上述驱动轴总成、车轮及减速器。本发明通过将驱动轴与驱动套通过花键沿轴线方向可滑动连接,并在驱动轴与驱动套远离相互连接的一端均通过固定式万向节与车轮和减速器连接,从而利用驱动轴与驱动套的伸缩来补偿由于车轮跳动时导致的轴杆的长度变化,减少整车振动。
