1. A steering mechanism, comprising:
a first directive wheel;
a second directive wheel;
a first driving device connected to the first directive wheel; and
a second driving device connected to the second directive wheel;
wherein the first driving device and the second driving device are configured to separately drive the first directive wheel and the second directive wheel respectively, thus making the first directive wheel and the second directive wheel deflect in a same direction as each other to achieve steering;
a hydraulic control system configured to supply liquid to the first driving device and the second driving device, thus making the first driving device and the second driving device separately drive the first directive wheel and the second directive wheel respectively, and making the first directive wheel and the second directive wheel deflect in the same direction;
a steering control device having a first working state and a second working state;
a steering part in transmission connection with the steering control device, wherein the steering part is configured to control the steering control device to switch between the first working state and the second working state; and
a liquid supply device, the liquid supply device being configured to supply liquid to the first driving device and the second driving device when the steering control device is in the first working state, thus making the first driving device and the second driving device respectively drive the first directive wheel and the second directive wheel to deflect leftwards in the same direction, and being also configured to supply the liquid to the first driving device and the second driving device when the steering control device is in the second working state, thus making the first driving device and the second driving device respectively drive the first directive wheel and the second directive wheel to deflect rightwards in the same direction;
a flow divider valve, wherein the liquid supplied by the liquid supply device flows into the first driving device and the second driving device through the flow divider valve and the steering control device in sequence; the flow divider valve is configured to regulate a proportion of flow of the liquid flowing into the first driving device from the steering control device to flow of the liquid flowing into the second driving device from the steering control device, thus making a deflection angle of the first directive wheel and a deflection angle of the second directive wheel be the same or different;
wherein the hydraulic control system further comprises:
a flow regulating valve, wherein the liquid supplied by the liquid supply device flows into the first driving device and the second driving device through the flow regulating valve, the flow divider valve, and the steering control device in sequence;
a vehicle speed sensor for acquiring a vehicle speed signal of a vehicle; and
a control unit configured to control the flow regulating valve to regulate the flow of the liquid flowing into the flow divider valve according to the vehicle speed signal.
