Embodiment Construction

[0037] Such as Figure 1 to Figure 5 As shown, the present invention provides a helicopter wheel brake controller, which is used to control the brake wheel brake, including a housing 1 and an end cover 2 arranged inside the housing, a first piston 3, a second piston 4, a spring 5. Piston rod 6, ejector rod 7, push rod 8 and other components.

[0038] The shell 1 can adopt various suitable structures, and its interior is stepped, including a first cylindrical cavity 11 and a second cylindrical cavity 12 connected coaxially, and the inner diameter of the first cylindrical cavity 11 is larger than the inner diameter of the second cylindrical cavity 12 . The housing 1 also includes a first open end communicating with the first cylindrical chamber 11 ( figure 2 The left side shown in ) and the second open end communicating with the second cylindrical chamber 12 ( figure 2 shown on the left).

[0039] The end cover 2 is arranged on the first opening end of the housing 1 through...

Abstract

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.

Description

technical field [0001] The invention relates to the design of a helicopter closed wheel brake hydraulic system, in particular to a helicopter wheel brake controller; Background technique [0002] At present, there are mainly two kinds of systems, the dynamic brake system and the closed wheel brake system. [0003] The dynamic braking system has a large braking force. The advantage is that the braking force is large and the operation is easy. The driver does not need a lot of force to brake; There is main system pressure leaking into the brake unit, causing nuisance braking. [0004] The closed wheel brake system is often used in the wheel brake system of small and medium-sized helicopters. It does not require an external power source and is not connected with the main system, so the safety of the main system is higher. [0005] The wheel brake hydraulic system is used for the dynamic brake and parking brake of the helicopter, and in its dynamic brake work, a control device...
