The invention discloses a vehicle steering device and system, the vehicle steering device comprises a booster cylinder, a centering cylinder, a steering rocker arm, a steering pull rod and a steering knuckle arm, the power end of the booster cylinder is in power connection with the steering rocker arm, one end of the centering cylinder is fixedly connected with a vehicle body, and the power end of the centering cylinder is in power connection with the steering rocker arm; when a vehicle steers, the power-assisted cylinder acts according to a steering instruction and pushes the steering rocker arm to rotate around the stand column assembly, the steering pull rod is pushed to linearly move through the steering rocker arm, then the wheels are driven to steer through the steering knuckle arm, and the centering cylinder does not apply force according to the steering instruction and acts along with the steering rocker arm. A steering gear is omitted, the steering mechanism is driven to steer through the combined action of the power-assisted cylinder and the centering cylinder, and compared with a traditional vehicle steering device, the vehicle steering device has the advantages of being high in modularization degree, high in integration degree and the like.

    本发明公开了一种车辆转向装置及转向系统,包括助力缸、对中缸、转向摇臂、转向拉杆和转向节臂,所述助力缸的动力端与所述转向摇臂动力相连,对中缸的一端与车身固连,对中缸的动力端与转向摇臂动力相连;其中,在车辆转向时助力缸根据转向指令动作并推动转向摇臂绕所述立柱总成旋转,通过转向摇臂推动转向拉杆直线移动,进而通过转向节臂带动车轮转向,对中缸根据转向指令不施力并跟随所述转向摇臂动作。本发明省略了转向器,通过助力缸和对中缸共同作用驱动转向机构进行转向,相比于传统的车辆转向装置具有模块化程度高、集成度高等优点。
