The invention discloses a hydraulic-electric hybrid driving system and method and a vehicle, a hydraulic driving motor is adopted to provide power for a hydraulic motor and is connected to a driving motor through a clutch, two driving modes of common driving of the hydraulic motor and the driving motor or independent driving of the driving motor are met, and meanwhile, the driving efficiency is improved. The reverse energy recovery function is achieved by adopting the matching relation between the power battery and the driving motor and the hydraulic motor, the part production technology difficulty of the system is low, a gearbox is omitted, hydraulic speed change is adopted, the arrangement space is good, the energy recovery function is combined, the braking performance is good, in addition, the power battery can be arranged on the two sides of a vehicle frame, the center of the vehicle is lowered, and the cost is reduced. And the stability of the vehicle in the running process is improved.
本发明公开一种液电混合驱动系统、方法及车辆,采用液压驱动电机为液压马达提供动力,并通过离合器连接到驱动电机,满足液压马达与驱动电机共同驱动或者驱动电机单独驱动两种驱动方式,同时,采用动力电池与驱动电机、液压马达之间的配合关系,实现反向能量回收的功能,该系统的零件生产技术难度低,并取消了变速箱,采用液压变速,布置空间好,结合能量回收功能,制动性能好,另外,动力电池能够布置于车架两侧,降低车辆中心,提高车辆行驶过程中的稳定性。
