The invention provides a steering system and an engineering vehicle. The steering system comprises a steering mechanism which comprises a steering axle, a steering wheel and a steering oil cylinder, and the steering oil cylinder is configured to drive the steering wheel to deflect left and right relative to the steering axle; a steering control mechanism; the transmission mechanism is configured to drive the steering wheel to deflect left and right relative to the steering axle; the full-hydraulic steering gear comprises a motor. The steering mode switching device is configured to enable the steering system to be switched between a first steering mode and a second steering mode, in the first steering mode, the steering control mechanism is in transmission connection with the transmission mechanism, the transmission mechanism responds to the control action of the steering control mechanism and drives the steering wheels to deflect, and in the second steering mode, the steering control mechanism drives the steering wheels to deflect. The steering control mechanism is in transmission connection with the motor, and the motor responds to the control action of the steering control mechanism and supplies oil to the steering oil cylinder, so that the steering oil cylinder drives the steering wheel to deflect. The steering system and the engineering vehicle can meet steering requirements under different working conditions.

    本公开提供一种转向系统和工程车辆。转向系统包括:转向机构,包括转向桥、转向轮和转向油缸,转向油缸被配置为驱动转向轮相对于转向桥左右偏转;转向操纵机构;传动机构,被配置为驱动转向轮相对于转向桥左右偏转;全液压转向器,包括马达;和转向模式切换装置,被配置为使转向系统在第一转向模式和第二转向模式之间切换,在第一转向模式,使转向操纵机构与传动机构传动连接,传动机构响应于转向操纵机构的操纵动作,驱动转向轮偏转,在第二转向模式,使转向操纵机构与马达传动连接,马达响应于转向操纵机构的操纵动作,向转向油缸供油,以使转向油缸驱动转向轮偏转。本公开的转向系统和工程车辆能够满足不同工况下的转向需求。
