The invention provides an electro-hydrostatic energy system for an undercarriage and a brake and a control method of the electro-hydrostatic energy system, and relates to the technical field of electro-hydrostatic actuators. The system comprises two motors and two hydraulic pumps, the output ends of the two hydraulic pumps are connected with a first output pipeline and a second output pipeline respectively, the first output pipeline and the second output pipeline are connected with a left brake pipeline and a right brake pipeline respectively, and the tail ends of the first output pipeline and the second output pipeline are connected with an undercarriage rising and falling pipeline; a second interface of each two-position three-way electromagnetic valve is connected with one interface of the undercarriage actuator through one first electromagnetic switch valve; the two second electromagnetic switch valves are respectively connected with the left brake actuator and the right brake actuator; the problems that in the prior art, a brake system and an undercarriage system are driven and controlled by independent subsystems respectively, and weight reduction and space utilization rate of an aircraft are not facilitated are solved.

    本发明提供一种用于起落架和刹车的电静液能源系统及其控制方法,涉及电静液作动器技术领域,包括:油箱;两个电机和两个液压泵,两个液压泵的输出端分别连接有第一输出管路和第二输出管路,第一输出管路和第二输出管路分别连接有左刹车管路和右刹车管路,且第一输出管路和第二输出管路的末端连接有起落架起落管路;两个二位三通电磁阀,每个二位三通电磁阀的第二接口经过一个第一电磁开关阀与起落架作动器的一个接口连接;两个第二电磁开关阀,分别与左刹车作动器和右刹车作动器连接;解决现有技术中刹车系统和起落架系统分别由独立的子系统进行驱动和控制,不利于飞行器减重和空间利用率的问题。
