The invention belongs to the technical field of vehicle equipment, and provides a power-assisted steering system, an oil supply system and an automobile, the power-assisted steering system mainly comprises an oil tank, an oil pump, a steering control valve and a steering gear, and the steering control valve communicates with an oil inlet pipeline and an oil return pipeline; the liquid inlet end of the oil inlet pipeline is communicated with the oil pump, and the liquid outlet end of the oil return pipeline is communicated with the oil tank; a left steering power cavity and a right steering power cavity are formed in the steering gear, and the steering control valve is communicated with the left steering power cavity and the right steering power cavity. The steering hand feeling and the steering force do not need to be simulated by a control unit, and the feedback of the road feeling can be clearer; meanwhile, the oil pump belongs to an existing component in an electric drive system, so that a power element and a corresponding electronic unit do not need to be additionally arranged, highly-integrated installation and application of the power-assisted steering system on a whole vehicle can be conveniently achieved, the application cost can be effectively reduced, and the overall economic benefit is better.

    本申请属于车辆设备技术领域,提供一种转向助力系统、供油系统及汽车,主要包括油箱、油泵、转向控制阀和转向器,所述转向控制阀上连通设置有进油管路、回油管路;所述进油管路的进液端与所述油泵连通,所述回油管路的出液端与所述油箱连通;所述转向器内设置有左转向动力腔、右转向动力腔,所述转向控制阀分别与所述左转向动力腔、右转向动力腔连通。本申请无需依靠控制单元模拟转向手感和力度,路感的反馈可以更为清晰;同时,所述油泵属于电驱系统中的既有构件,因此无需再额外增设动力元件以及相应的电子单元,从而可以便于实现转向助力系统在整车上的高度集成式安装应用,应用成本可以有效降低,整体经济效益更好。
