Hydraulic system of wheel holding mechanism

Abstract

The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic system of a wheel holding mechanism. In order to solve the problems that an existing aircraft landing gear lacks a perfect hydraulic system during use, the output of the aircraft landing gear is unstable, the riding comfort is affected, and tires of the landing gear are seriously worn, the following technical scheme is provided: the system comprises a hydraulic system, an operation monitoring system and a fault feedback system, the output end of the operation monitoring system is connected with the input end of the hydraulic system and the input end of the fault feedback system. The hydraulic control system is stable and accurate in use, the oil cylinder is effectively and stably output and used, the use stability and safety of the aircraft landing gear are improved, the service life of equipment is prolonged, the hydraulic system is monitored, faults are fed back in time, optimization of the hydraulic system is facilitated, and the hydraulic control system is mainly applied to hydraulic control over the aircraft landing gear.

Description

technical field [0001] The invention relates to the technical field of hydraulic control systems, in particular to a hydraulic system of a wheel holding mechanism. Background technique [0002] The landing gear is the only component that supports the entire aircraft, so it is an integral part of the aircraft. The aircraft landing gear controls the operating state of the oil cylinder through the hydraulic system to ensure the retraction and adjustment of the aircraft landing gear, along with the pressure and flow of the hydraulic system. a substantial increase. Therefore, the patent "CN209479960U" proposes "an aircraft landing gear retractable hydraulic system". In this scheme, by adjusting the pressure regulating valve, the oil supply pressure of the system can be adjusted to meet the pressure requirements required for the test; an unloading valve is provided. , the set pressure of the unloading valve is higher than the rated working pressure of the system to protect the sy...
