The invention discloses a steering axle, a steering system and a vehicle, a trapezoidal transverse pull rod of the steering axle structure adopts a three-section ball hinge connection design, a power assisting cavity and a rack are designed in the trapezoidal transverse pull rod, the rack is connected through a motor-driving gear, and the steering angle of the steering axle is adjusted according to information such as a steering mode, the vehicle speed and the steering angle of the axle. The motor is controlled to drive the trapezoidal transverse pull rod to move in the axial direction, then the tire turning angle is adjusted, and power-assisted steering is achieved through the hydraulic power-assisted cavity; a motor brake is used for unlocking or locking the motor, and various steering modes are achieved. The steering design mode is high in steering return capacity, clear in front and rear wheel steering angle relation, high in control precision, good in power assisting effect and suitable for various steering modes.

    本发明公开了一种转向桥、转向系统及车辆,其中转向桥结构的梯形横拉杆采用三段式球绞连接设计,在梯形横拉杆中设计助力腔和齿条,通过电机‑主动齿轮连接齿条,根据转向模式、车速及一桥转向角度等信息,控制电机来驱动梯形横拉杆沿其轴向运动,进而调节轮胎转角,并通过液压助力腔实现转向助力;利用电机制动器实现对电机的解锁或锁止,实现各种转向模式。该转向设计模式的转向回正能力强,前、后轮转角关系明确,控制精度高,助力效果好,适用于多种转向模式。
