The invention discloses a steer-by-wire limiting device, and further provides a steer-by-wire system and a steer-by-wire motor vehicle based on the steer-by-wire limiting device. In the steer-by-wirelimiting device, a limiting part is arranged on a steering shaft sleeve, the limiting part can convert the rotary motion of a steering shaft into the linear motion of the limiting part, and the limiting part moves in a limiting space, is limited by a limiting disc and can limit the rotation of the steering shaft after being limited. The moving distance of the limiting part is in direct proportionto the rotating angle of the steering shaft, and the rotating angle of the steering shaft can be limited by limiting the moving distance of the limiting part. The rotating angle of a steering wheel inthe steer-by-wire system can be limited. The steer-by-wire system is simple in structure, the rotation angle of the steering wheel is limited accurately and adjustable, and the safety of automobile driving is improved to a great extent by optimizing the mechanical structure of the steer-by-wire system.
本发明公开了一种线控转向限位装置,基于该线控转向限位装置本发明还提供了一种线控转向系统以及一种线控转向式机动车。在线控转向限位装置中,本发明在转向轴套筒上设置有限位部件,限位部件可以将转向轴的旋转运动转换成自身的直线运动,限位部件在限位空间内运动,其受限位盘的限位,在限位部件限位后能够限制转向轴的转动。限位部件的移动距离与转向轴的旋转角度成正比,通过对限位部件的移动距离限定,就能够实现转向轴旋转角度的限定。本发明能够实现线控转向系统中方向盘旋转角度的限定。本发明结构简单,方向盘旋转角的限定精准、可调,本发明通过对线控转向系统进行机械结构优化,极大程度地提高了汽车驾驶的安全性。
