Embodiment Construction

[0020] This embodiment is a cylinder block damper, including a valve core 1 , an adjusting nut 2 , a spring 3 and a sealing ring 4 . Wherein the spring 3 is installed in the damper mounting hole of the cylinder block 5, so that the bottom surface of the spring is attached to the bottom surface of the damper mounting hole. The lower end of the spool 1 is inserted into the mounting hole of the damper, and the valve core is slidably matched with the mounting hole of the damper. An adjusting nut 2 is sleeved at the opening of the damper installation hole, and the pressing rod in the adjusting nut is pressed against the center of the upper end surface of the valve core. When the adjusting nut is rotated, the spool moves up and down under the action of the adjusting nut, so that the damping holes on the spool respectively correspond to and communicate with the oil passage holes on the cylinder block 5 .

[0021] The spool 1 is cylindrical, and there is a radially protruding slider ...

Abstract

The invention relates to an aircraft brake wheel cylinder seat damper. A spring is installed on the bottom surface of a damper mounting hole of a cylinder seat. The lower end of a valve core is enclosed into the damper mounting hole, and the valve core is enabled to be in sliding fit with the damper mounting hole. Three damping holes with different diameters are formed in the valve core, by adjusting the screw-in depth of nuts and threads, the valve core is enabled to move up and down in the cylinder seat, so that the corresponding damping holes communicate with pipeline holes of the cylinderseat to achieve the purpose of adjusting damping. An eccentric cam body of the valve core is in clearance fit with a mounting hole of the cylinder seat to enable the damper mounting hole to communicate with the pipeline holes of the cylinder seat to prevent fluid in the valve core form sealing. According to the aircraft brake wheel cylinder seat damper, the defect that the suitable dampers can only be screened by experiments due to the face that the non-detachable cylinder seat damper structure which is widely used at home and abroad needs to process dampers and cylinder seats with different hole diameters is overcome. The purpose of shortening the development cycle and reducing the development costs is realized.

Description

technical field [0001] The invention relates to the technical field of aviation machinery, in particular to a cylinder block damper used for braking wheels of an aircraft. Background technique [0002] Such as Figure 1-2 As shown, the aviation brake wheel generally consists of a wheel assembly and a brake device. The brake device is composed of a cylinder block assembly, a brake disc assembly, a brake housing and other components; the brake disc assembly generally consists of a compression disc, a moving disc, a static disc, and a pressure bearing disc. After the aircraft lands, the brake system obtains the output pressure signal through the aircraft brake command sensor (pedal). The pressure signal will be converted into the output pressure of the brake system and input into the cylinder block assembly, and the cylinder block will push the piston assembly installed in it to move to generate piston thrust; The frictional resistance generated by the axial force of the brak...
