The invention discloses a limiting device, a steer-by-wire system and a vehicle. The limiting device comprises a shell, a rotating shaft, a lead screw, a first limiting stopper, a second limiting stopper and a sliding part. A limiting cavity is formed in the shell. The rotating shaft is provided with a limiting shaft section, and at least part of the limiting shaft section penetrates through the limiting cavity. The lead screw is arranged on the periphery of the limiting shaft section. The first limiter and the second limiter are arranged on the limiting shaft section and located at the two ends of the lead screw respectively. The sliding part is arranged in the limiting cavity, is in sliding connection with the shell and is in threaded connection with the lead screw. Wherein the first limiting device is provided with a first limiting part, the second limiting device is provided with a second limiting part, a first abutting part is arranged on the side, close to the first limiting device, of the sliding part in a protruding mode, and a second abutting part is arranged on the side, close to the second limiting device, of the sliding part in a protruding mode. The sliding part enables the first abutting part to abut against the first limiting part or enables the second abutting part to abut against the second limiting part through movement. In this way, excessive rotation of the rotating shaft can be limited.

    本申请公开了限位装置、线控转向系统和车辆。限位装置包括壳体、转轴、丝杠、第一限位器、第二限位器和滑动部。壳体内部具有限位腔体。转轴具有限位轴段,限位轴段至少部分穿设于限位腔体。丝杠设置于限位轴段外周。第一限位器和第二限位器设置于限位轴段,且分别位于丝杠两端。滑动部设置于限位腔体内,与壳体滑动连接,且与丝杠螺纹连接。其中,第一限位器具有第一限位部,第二限位器具有第二限位部,滑动部靠近第一限位器的一侧凸设有第一抵接部,滑动部靠近第二限位器的一侧凸设有第二抵接部。滑动部通过移动使第一抵接部与第一限位部抵接,或者使第二抵接部与第二限位部抵接。通过上述方式,本申请能够限制转轴转动过度。
