The invention provides a disconnectable driving shaft and hub bearing connecting mechanism and a vehicle. The disconnectable driving shaft and hub bearing connecting mechanism comprises a hub bearing, and a first spline part is formed on the inner side of the hub bearing; the driving shaft assembly is arranged on the hub bearing in a penetrating manner; the sliding spline sleeve is installed at the first end of the driving shaft assembly, a second spline part is formed on the outer side of the sliding spline sleeve, and the second spline part can be meshed with the first spline part; the actuator assembly is connected with the sliding spline sleeve, the actuator assembly can drive the sliding spline sleeve to move in the axial direction of the driving shaft assembly, under the condition that the sliding spline sleeve moves to a first preset position, the second spline part is meshed with the first spline part, and under the condition that the sliding spline sleeve moves to a second preset position, the second spline part is separated from the first spline part. According to the breakable driving shaft and hub bearing connecting mechanism and the vehicle, the problem that energy is consumed in the variable-speed running process of the vehicle due to the fact that a driving shaft assembly has rotational inertia can be solved.
本发明提供一种可断开式驱动轴与轮毂轴承连接机构及车辆,可断开式驱动轴与轮毂轴承连接机构包括轮毂轴承,轮毂轴承的内侧形成有第一花键部;驱动轴总成,驱动轴总成穿设于轮毂轴承;滑动花键套,安装于驱动轴总成的第一端,滑动花键套的外侧形成有第二花键部,第二花键部能够与第一花键部啮合;以及执行器总成,与滑动花键套连接,执行器总成能够驱动滑动花键套沿驱动轴总成的轴向运动,在运动至第一预设位置的情况下,第二花键部与第一花键部啮合,在运动至第二预设位置的情况下,第二花键部从第一花键部中脱离。该可断开式驱动轴与轮毂轴承连接机构及车辆能够解决驱动轴总成具有转动惯量,导致车辆在变速行驶的过程中产生能量消耗的问题。
