The invention relates to the design of a closed helicopter wheel brake hydraulic system, in particular to a helicopter wheel brake controller. The helicopter wheel brake controller aims to solve at least one technical problem of an existing brake controller. The helicopter wheel brake controller is used for controlling a helicopter wheel brake to perform braking and comprises a shell, an end cover, a first piston, a second piston, a spring, a piston rod, an ejector rod and a push rod, wherein the first piston is coaxially arranged in a third cylindrical cavity in a sealed mode, the second piston is coaxially arranged in a first cylindrical cavity in a sealed mode, the spring is coaxially arranged in the first cylindrical cavity, the piston rod is coaxially arranged in the shell, the ejector rod is arranged in the piston rod in the manner of sliding axially along the piston rod, and one end of the push rod coaxially penetrates through the second open end of the shell and is fixedly connected with the end face, close to the second open end, of the piston rod. According to the helicopter wheel brake controller, multistage control is achieved through the cooperation of the first piston and the second piston in the shell, and sufficient pressure output of the closed helicopter wheel brake hydraulic system can be achieved through small control force.
