Electro-hydraulic hybrid drive system
The invention relates to an electro-hydraulic hybrid driving system, in particular to an electro-hydraulic hybrid driving system with an energy recovery function. Comprising a prime mover, a main pump and a main generator which are driven by the prime mover, an overflow valve, an electrochemical energy storage device powered by the main generator, at least one actuator assembly and an oil tank or an oil return low-pressure rail, and further comprises at least one public high-pressure rail supplied with oil by the main pump, each actuator assembly comprises a motor/generator, a first hydraulic pump/motor, a second hydraulic pump/motor and an actuator, the motors/generators are electrically connected with the electrochemical energy storage devices, and the oil suction control valves correspond to the oil outlet control valves in pairs and jointly control the first hydraulic pumps/motors to operate in four quadrants. The second hydraulic pump/motor is hydraulically coupled with the actuator through a pipeline. According to the invention, the speed of the motor/generator can be accurately controlled, the rated power required by the motor/generator can be reduced, and modularization and expandability can be realized on the basis of an energy recovery function.
本发明涉及电液混合驱动系统，尤其是具有能量回收功能的电液混合驱动系统。包括原动机、由原动机驱动的主泵和主发电机、溢流阀、由主发电机供能的电化学蓄能装置、至少一个执行器组件和油箱或回油低压轨，其中，还包括至少一个由主泵供油的公共高压轨，每个所述的执行器组件包括电机/发电机、第一液压泵/马达、第二液压泵/马达和执行器，电机/发电机与电化学蓄能装置电连接，吸油控制阀与出油控制阀两两对应，共同控制第一液压泵/马达四象限运行，第二液压泵/马达通过管路与执行器液压耦合。本发明既能精确控制电机/发电机的速度，又能降低电机/发电机所需的额定功率，同时在具有能量回收功能的基础上，可模块化、可扩展化。
