The invention discloses a commercial vehicle emergency steering system and a commercial vehicle, the emergency steering system is added in an original steering hydraulic system, and the emergency steering system comprises an integrated emergency steering gear, a steering oil pump, a steering oil tank and a steering gear which are arranged on a vehicle frame; the steering oil tank adopts double oil outlets to respectively supply oil to the steering oil pump and the integrated emergency steering gear; a first hydraulic loop is formed among the steering oil tank, the steering oil pump, the integrated emergency steering gear, the steering gear and the steering oil tank; a second hydraulic loop is formed among the steering oil tank, the integrated emergency steering gear, the steering gear and the steering oil tank; when the steering oil pump operates normally, the first hydraulic circuit controls steering, and the second hydraulic circuit is in a standby state; when the steering oil pump is abnormal, the second hydraulic loop operates immediately, and emergency steering is achieved. According to the emergency steering system of the commercial vehicle, due to the fact that no layout design sample exists in the early stage, the design is brand new, emergency steering and alarming can be achieved, and the requirements of laws and regulations are met.
本发明公开了一种商用车应急转向系统及商用车,在原转向液压系统中增加应急转向系统,应急转向系统包括:布置在车架上的集成式应急转向器、转向油泵、转向油罐和转向器;转向油罐采用双出油口,分别给转向油泵和集成式应急转向器供油;转向油罐、转向油泵、集成式应急转向器、转向器、转向油罐之间形成第一液压回路;转向油罐、集成式应急转向器、转向器、转向油罐之间形成第二液压回路;当转向油泵正常运行时,第一液压回路控制转向,第二液压回路处于待机状态;当转向油泵异常时,第二液压回路立刻运行,实现应急转向。本发明提供的商用车应急转向系统因前期无此类布置设计样本,故该设计为全新设计,能实现应急转向及报警,满足法规要求。
