The invention relates to the field of automobile power-assisted steering, in particular to an emergency steering system. The system comprises an oil can, a main oil pump, an emergency module and a steering gear box, the oil pot, the main oil pump, the emergency module, the steering gear box and the oil pot are communicated in a closed-loop mode, and the oil pot is communicated with the emergency module; when the main oil pump normally operates, hydraulic oil sequentially circulates along the oil can, the main oil pump, the emergency module, the steering gear box and the oil can; when the main oil pump is damaged and the hydraulic oil flow is lower than a set flow value, the main path hydraulic oil sequentially circulates along the oil can, the main oil pump, the emergency module, the steering gear box and the oil can, and the auxiliary path hydraulic oil sequentially circulates along the oil can, the emergency module, the steering gear box and the oil can; and during trailer, the main oil pump does not convey hydraulic oil, and the emergency module operates and provides hydraulic oil for the steering gear box. The hydraulic steering system solves the problems that in the running process of an existing hydraulic steering system vehicle, no hydraulic power is provided after a main oil pump loses efficacy, and no hydraulic power is provided for the steering system when the vehicle breaks down.
本发明涉及汽车助力转向领域,具体为一种应急转向系统。其包括油壶、主油泵、应急模组和方向机;油壶、主油泵、应急模组、方向机和油壶闭环连通,油壶与应急模组连通;主油泵正常运行时,液压油沿油壶、主油泵、应急模组、方向机和油壶顺序流通;主油泵损坏,液压油流量低于设定流量值时,主路液压油沿油壶、主油泵、应急模组、方向机和油壶顺序流通,辅路液压油沿油壶、应急模组、方向机和油壶顺序流通;当拖车时,主油泵不输送液压油,应急模组运行并向方向机提供液压油。本发明解决了现有液压转向系统车辆在行驶过程中主油泵失效后无液压助力和车辆故障拖车时转向系统无液压助力的问题。
