The invention provides a steer-by-wire column with a rotation limiting structure, a steering system and a vehicle, and belongs to the technical field of vehicle steering. The device comprises an upper column casing, wherein a mounting opening is formed in the circumferential side wall of the upper column casing; the steering shaft rotates clockwise or anticlockwise in the upper column casing, and a spiral guide groove is formed in the circumferential side wall of the steering shaft in the axis direction of the steering shaft; the mounting base is arranged on the upper column casing and located at the mounting opening, a limiting groove is formed in the mounting base in the axis direction of the steering shaft, and the limiting groove and the spiral guide groove are oppositely arranged through the mounting opening; and the sliding piece is located in the spiral guide groove and the limiting groove at the same time, and when the steering shaft rotates, the spiral guide groove pushes the sliding piece to move to the end of the limiting groove so as to limit the number of rotation turns of the steering shaft. According to the invention, the rotation of the steer-by-wire column cannot exceed the stroke, and the use safety of the vehicle is ensured.

    本发明提供一种具有旋转限位结构的线控转向管柱、转向系统及车辆,属于车辆转向技术领域。本发明包括上柱筒,周向侧壁上设置有安装口;转向轴,在所述上柱筒内顺时针或逆时针旋转,且所述转向轴的周向侧壁上沿自身轴线方向设置有螺旋导向槽;安装座,设置在所述上柱筒上并位于所述安装口处,且所述安装座上沿所述转向轴的轴线方向设置有限位槽,所述限位槽和所述螺旋导向槽通过所述安装口相对设置;以及滑动件,同时位于所述螺旋导向槽和所述限位槽内,当所述转向轴旋转时,所述螺旋导向槽推动所述滑动件移动至所述限位槽的端部,以限制所述转向轴的旋转圈数。本发明能够确保线控转向管柱的转动不会超出行程,保证车辆的使用安全。
