Hybrid vehicle two-kinetic-source engaging and disengaging system

The invention relates to a hybrid vehicle two-kinetic-source engaging and disengaging system, which comprises an engaging and disengaging execution oil cylinder which is communicated with two kinetic sources, wherein the two kinetic sources comprise an engine steering booster oil pump and an electric steering oil pump, wherein both a hydraulic oil output port of the engine steering booster oil pump and a hydraulic oil output port of the electric steering oil pump are communicated with a hydraulic oil input port of the engaging and disengaging execution oil cylinder. The hybrid vehicle two-kinetic-source engaging and disengaging system adopting the above structure utilizes the electric steering oil pump when an engine does not work and utilizes the steering booster oil pump of the engine when the engine works, so the failure risk of an automatic engaging and disengaging hydraulic system can be reduced, the loss of the energy which is transformed between the engine mechanical energy and the electric steering boosting system mechanical energy can be reduced relative to the situation that only a single kinetic source of the electric steering oil pump is utilized, and the economic performance of the engaging and disengaging system can be improved. The hybrid vehicle two-kinetic-source engaging and disengaging system ahs a simple structure, low cost and a wide application range.
