The invention belongs to the technical field of emergency steering control of commercial vehicles, and discloses an emergency steering power device of a commercial vehicle and the commercial vehicle. The emergency steering power device for the commercial vehicle comprises a driving mechanism, an emergency valve and an emergency pump, wherein a shell of the driving mechanism is fixedly arranged on a vehicle body; the emergency valve is fixedly arranged on the shell, a first oil channel is formed in the emergency valve, and the two ends of the first oil channel communicate with an outlet of the main oil pump and the power steering gear correspondingly. The emergency valve is configured to transmit power steering oil of an outlet of the main oil pump to the power steering gear so as to complete power-assisted steering. The power input end of the emergency pump is connected with the power output end of the driving mechanism, a second oil channel is formed in the emergency pump and communicates with the first oil channel, and the driving mechanism can drive the emergency pump to work so that the emergency pump can provide power steering oil for the power steering gear to complete emergency power steering. The distance between the emergency valve and the emergency pump is shortened, the structure is simple, and the space arrangement difficulty is reduced.

    本发明属于商用车应急转向控制技术领域,公开了一种商用车应急转向动力装置和商用车。商用车应急转向动力装置包括驱动机构、应急阀和应急泵,驱动机构的壳体固定设置在车身上;应急阀固定设置在壳体上,应急阀内设有第一油道,第一油道的两端分别连通主油泵出口和动力转向器;应急阀被配置为将主油泵的出口的动力转向油传输给动力转向器以完成转向助力;应急泵的动力输入端连接驱动机构的动力输出端,应急泵的内设有第二油道,第二油道与第一油道连通设置,驱动机构能够驱动应急泵工作使得应急泵向动力转向器提供动力转向油以完成应急转向助力。本发明缩短了应急阀和应急泵之间的间距,且结构简单,空间布置难度降低。
