The invention provides a vehicle rear wheel active steering device and a vehicle, and relates to the technical field of vehicles, the vehicle rear wheel active steering device comprises a driving part, a transmission mechanism, a transmission shaft structure and two fork arm assemblies, and the two axial ends of the transmission shaft structure are connected with the corresponding fork arm assemblies respectively; the ends, away from the transmission shaft structure, of the two fork arm assemblies are used for being connected with corresponding rear wheels of the vehicle correspondingly. The driving part is connected with the transmission mechanism, the transmission shaft structure is connected with the transmission mechanism, and the transmission shaft structure is used for converting rotary motion of the transmission mechanism into axial motion of the transmission mechanism; the transmission shaft structure is used for being in sliding fit with a limiting piece arranged on a chassis, and the limiting piece is used for limiting rotation of the transmission shaft structure. On the basis that the active steering action of the rear wheels is achieved, rotation of the transmission shaft structure is limited through the limiting piece.

    本发明提供了一种车辆后轮主动转向装置及车辆,涉及车辆技术领域,该车辆后轮主动转向装置包括驱动部、传动机构、传动轴结构和两个叉臂组件,所述传动轴结构的轴向两端分别连接对应的所述叉臂组件,两个所述叉臂组件远离所述传动轴结构的一端用于分别连接车辆对应的后轮;所述驱动部与所述传动机构连接,所述传动轴结构与所述传动机构连接,所述传动轴结构用于将所述传动机构的旋转运动转换为自身的轴向移动;所述传动轴结构用于与设置于底盘上的限位件滑动配合,所述限位件用于限制所述传动轴结构的转动。本发明可通过在实现对后轮的主动转向动作的基础上,通过限位件限制传动轴结构转动。
