The invention relates to the field of engineering machinery, and provides an emergency steering system, a chassis and an operation machine, which comprises an oil supply device, a power-assisted steering assembly, an emergency pump and a reversing conduction assembly. The emergency pump is used for being in transmission connection with the gearbox, and when the emergency pump rotates forwards or reversely, the reversing conduction assembly can enable the emergency pump to drive hydraulic oil to flow to the power-assisted steering assembly from the oil supply device. According to the emergency steering system provided by the invention, the emergency pump incapable of supplying oil in two directions is combined with the reversing conduction assembly, so that the effect of supplying oil in two directions is realized, and compared with a plunger pump in the prior art, the emergency steering system provided by the invention can suck oil from the oil supply device no matter whether the emergency pump rotates forwards or reversely, so that the oil supply efficiency is improved. Meanwhile, the hydraulic power steering device has the advantages of being simple in structure and low in cost.
本发明涉及工程机械领域,提供一种应急转向系统、底盘和作业机械,包括供油装置、转向助力组件、应急泵和换向导通组件。应急泵用于与变速箱传动连接,当应急泵正转或反转时,换向导通组件均能使应急泵驱动液压油由供油装置流向转向助力组件。本发明提供的应急转向系统使用无法双向供油的应急泵与换向导通组件相结合,使其实现双向供油的效果,与现有技术中的柱塞泵相比,本发明提供的应急转向系统在实现无论应急泵正转还是倒转,均可向供油装置吸油,并将液压油输送至转向助力组件的效果的同时,具备结构简单,成本低的优点。
