The invention relates to an emergency steering system based on gearbox two-shaft power take-off. The emergency steering system based on gearbox two-shaft power take-off is installed on a chassis and comprises a gearbox, a power takeoff, a first steering oil can, a second steering oil can, a transmission shaft, an emergency steering pump, an emergency steering valve, a circulating ball steering gear and an electric hydraulic steering pump; and the power takeoff is installed on the gearbox; the transmission shaft is installed on the gearbox through a flange plate; the emergency steering pump isinstalled on the power takeoff; the first steering oil can, the second steering oil can, the emergency steering valve, the circulating ball steering gear and the electric hydraulic steering pump are all installed on a frame; and the first steering oil can, the second steering oil can, the emergency steering pump, the emergency steering valve, the circulating ball steering gear and the electric hydraulic steering pump are connected with one another through a plurality of steering oil pipes. When the high-voltage electric or electric hydraulic steering pump breaks down, the emergency system is automatically started, necessary energy is provided for the steering system, and the reliability of a vehicle is improved.

    本发明公开了一种基于变速箱二轴取力的应急转向系统,安装于底盘上,包括变速箱、取力器、第一转向油壶、第二转向油壶、传动轴、应急转向泵、应急转向阀、循环球转向器以及电动液压转向泵,取力器安装在变速箱上;传动轴通过法兰盘安装在变速箱上,应急转向泵安装在取力器上;第一转向油壶、第二转向油壶、应急转向阀、循环球转向器以及电动液压转向泵均安装在车架上,第一转向油壶、第二转向油壶、应急转向泵、应急转向阀、循环球转向器以及电动液压转向泵之间通过若干条转向油管相互连接。本发明当高压电或者电动液压转向泵出现故障时,该应急系统自动启动,给转向系统提供必要的能量,提高了车辆的可靠性。
