The embodiment of the invention provides a half-axle differential mechanism, a drive axle and a vehicle, and aims to solve the technical problem of how to realize independent control of wheels in an electric vehicle. The half axle differential comprises a slidable first drive plate. The first drive plate is located at different positions and corresponds to different working conditions. When the first drive plate slides to the first position, the first drive plate is in transmission connection with the first shaft and the shell, and if the first drive plate rotates freely, the forward torque is transmitted to a wheel connected with the half shaft differential through the bevel gear assembly. At this time, the wheel rotates forward. When the first drive plate slides to the second position, the first drive plate and the first shaft are disconnected, rotation of the first drive plate is limited, and the reverse torque is transmitted to the wheel connected with the half shaft differential through the bevel gear assembly. At this time, the wheel rotates reversely. By adjusting the position of the first drive plate, the half-axle differential mechanism can achieve the function of outputting forward torque and not outputting torque, and therefore independent control over wheels and in-situ steering are achieved.

    本申请实施例提供一种半轴差速器、驱动桥以及车辆,用于解决如何实现电动汽车中车轮的独立控制的技术问题。该半轴差速器包括可滑动的第一拨盘。第一拨盘位于不同的位置,对应不同的工况。当第一拨盘滑动至第一位置时,第一拨盘与第一轴传动连接,且第一拨盘与外壳传动连接,若第一拨盘自由转动,正向转矩经由锥齿轮组件传递给与半轴差速器连接的车轮。此时,车轮正转。当第一拨盘滑动至第二位置时,第一拨盘和第一轴断开连接,且第一拨盘被限制转动,反向转矩经由锥齿轮组件传递给与半轴差速器连接的车轮。此时,车轮反转。通过调整第一拨盘的位置,半轴差速器可以实现输出正向转矩、不输出转矩的功能,从而实现车轮的独立控制,以及原地转向。
