The invention discloses a timely four-wheel drive system of a hybrid electric vehicle, and relates to the technical field of hybrid electric vehicles. The timely four-wheel drive system comprises an oil-electricity hybrid power system and a hydraulic hub system. When the vehicle runs on a good road surface and has no high power performance requirement, the economy of the whole vehicle can be guaranteed by utilizing the oil-electricity hybrid power system; and when the vehicle runs on a road surface with a low adhesion rate or has a power performance requirement such as climbing a large slope,the hydraulic hub system is started to enable the whole vehicle to perform four-wheel drive running under the combined drive of two power sources or three power sources, so that the running safety andthe power performance of the whole vehicle are improved. According to the timely four-wheel drive system of the hybrid electric vehicle, the driving power performance, economy and safety of the wholevehicle are guaranteed. Meanwhile, the additional hydraulic hub system is simple in structure, small in mass and reliable in work, and the manufacturing and using cost is further saved.
本发明公开了一种混合动力汽车适时四轮驱动系统,涉及混合动力汽车技术领域,包括油电混合动力系统和液压轮毂系统。在良好路面行驶且无较大动力性需求时,通过利用油电混合动力系统可以保证整车经济性;在附着率较低路面行驶或有动力性需求如爬较大坡度时,通过开启液压轮毂系统可以使整车在二动力源或三动力源联合驱动下进行四轮驱动行驶,从而提升整车行驶安全性与动力性;本发明提供的一种混合动力汽车适时四轮驱动系统保证了整车行驶动力性、经济性与安全性,同时附加的一套液压轮毂系统结构简单、质量较小且工作可靠,进一步节约了制造与使用成本。
