The invention relates to a hydraulic oil supply system and a vehicle. The system comprises a hydraulic source, a cooling lubricating oil way module, a first mechanical oil pump, a second mechanical oil pump and an electronic oil pump. The cooling and lubricating oil way module comprises a cooling and lubricating oil way, and the output end of the oil way is connected with at least one of the generator, the driving motor, the transmission and the clutch and used for cooling and lubricating at least one of the generator, the driving motor, the transmission and the clutch. The first mechanical oil pump, the second mechanical oil pump and the electronic oil pump are connected with the hydraulic source and the input end of the cooling lubricating oil way. Therefore, the three oil pumps are matched with one another, the two mechanical oil pumps operate to supply oil, and the electronic oil pump supplies the oil according to needs, so that almost perfect matching of the needs and the supply can be achieved, oil flow waste and energy consumption are reduced to the maximum extent, meanwhile, the displacement of the two mechanical oil pumps can be minimized, the power of the electronic oil pump can be minimized, and the system cost is reduced. And moreover, excessive parts are not added, so that the system cost is further reduced.
本公开涉及一种液压供油系统及车辆,系统包括:液压源、冷却润滑油路模块、第一机械油泵、第二机械油泵及电子油泵;冷却润滑油路模块包括冷却润滑油路,油路的输出端与发电机、驱动电机、变速器及离合器中的至少一个连接,用于冷却润滑发电机、驱动电机、变速器及离合器中的至少一个,第一机械油泵、第二机械油泵及电子油泵均与液压源、冷却润滑油路的输入端分别连接。这样,三个油泵之间互相配合,双机械油泵运转供油,电子油泵按需供给,从而能做到需求与供给几乎完美的匹配,最大程度地降低油液流量浪费,降低能耗,同时可以把两机械油泵排量做到最小,电子油泵的功率做到最低,降低系统成本。并且,没有增加过多的零件,进一步降低系统成本。
