The invention provides a power switching device and a vehicle, the power switching device comprises a shaft sleeve, an input shaft, an output shaft, a control mechanism and a driving piece, the input shaft is provided with a linear external spline, the output shaft is provided with an inclined external spline, and the shaft sleeve is provided with a linear internal spline and an inclined internal spline; the shaft sleeve is in meshed connection with the input shaft through linear internal and external splines, the control mechanism pushes the shaft sleeve to slide from an initial position to a first position with small thrust, the driving piece drives the shaft sleeve to rotate at a speed larger than that of the output shaft, and the shaft sleeve generates component force sliding towards the output shaft through meshing of the shaft sleeve and the inclined internal and external splines of the output shaft. The shaft sleeve is driven to automatically slide from the first position to the second position on the premise that the control mechanism does not continuously give thrust, the input shaft is connected with the output shaft, the thrust is reduced, the action time of the thrust is shortened, system work is reduced, and the problem that an existing device is large in thrust and long in thrust time, and consequently system work is large is solved.

    本发明提供了一种动力切换装置及车辆,包括轴套、输入轴、输出轴、控制机构和驱动件,输入轴设置有直线外花键,输出轴设置有倾斜外花键,轴套设置有直线内花键和倾斜内花键,当轴套处于初始位置,轴套与输入轴通过直线内外花键啮合连接,控制机构用较小推力推动轴套从初始位置滑至第一位置,驱动件带动轴套转速大于输出轴转速,并通过轴套与输出轴倾斜内外花键的啮合,使轴套产生一个向输出轴滑动的分力,促使轴套在控制机构不继续给予推力的前提下,从第一位置自行滑至第二位置,使输入轴与输出轴连接,在减小推力的同时减少推力的作用时间,从而减少系统做功,解决了现有装置推力大且推力时间长造成系统做功较多的问题。
