The invention provides a hydraulic system, a hybrid power transmission and a vehicle. The hydraulic system comprises an oil supply module, a high-pressure module and a cooling and lubricating module. The oil supply module comprises an electric pump which is connected with the high-pressure module; the high-pressure module is configured to supply oil to an executing mechanism of the vehicle through the electric pump, the cooling and lubricating module is used for cooling and lubricating a to-be-cooled part of the vehicle, the cooling and lubricating module comprises a first switch valve, and the first switch valve is arranged between the electric pump and the to-be-cooled part and used for being opened or closed according to the running mode of the vehicle. Through the arrangement, the oil quantity requirements of the high-pressure module and the cooling and lubricating module under different vehicle speeds or different modes can be met, oil can be independently supplied to an executing mechanism of the vehicle through the electric pump, the flow of the high-pressure module can be supplemented to the cooling and lubricating module through the electric pump, and the working efficiency of the hydraulic system is greatly improved.
本申请提供一种液压系统、混合动力变速器及车辆,液压系统包括供油模块、高压模块和冷却润滑模块;供油模块包括电动泵,电动泵与高压模块连接;高压模块被配置为通过电动泵为车辆的执行机构供油,冷却润滑模块用于对车辆的待冷却件进行冷却润滑,冷却润滑模块包括第一开关阀,第一开关阀设置于电动泵和待冷却件之间,第一开关阀用于根据车辆的运行模式打开或关闭。通过该设置,能够适应不同车速或不同模式下高压模块和冷却润滑模块的油量需求,既能通过电动泵单独为车辆的执行机构供油,也能通过电动泵将高压模块的流量补充至冷却润滑模块,大大提升了液压系统的工作效率。
