Abstract

The present application relates to a double-switch-valve-based self-powdering brake apparatus and a system. The apparatus comprises a drive mechanism, a hydraulic pump, a first switch valve, a second switch valve and a brake assembly; the oil inlet port of the first switch valve is connected with the oil outlet port of the hydraulic pump, a control end of the first switch valve opens or closes the oil outlet port of the first switch valve on the basis of a first control instruction received by the control end; the oil inlet port of the second switch valve is connected with the oil outlet port of the first switch valve, the oil outlet port of the second switch valve is connected with the oil inlet port of the hydraulic pump, the second switch valve opens or closes the oil outlet port of the second switch valve on the basis of a second control instruction received by the control end; the brake assembly is connected with the oil outlet port of the first switch valve for generating a brake actuation signal on the basis of the flow rate of the oil outlet port of the first switch valve. The double switch valve-based self-powdering brake apparatus and system can avoid the problems of poor contamination resistance and serious oil leakage of the self-powdering brake device in the prior art.

Description

Technical field [0001] This application relates to the technical field of aircraft brake systems, in particular to a self-feeding energy brake device and system based on dual on-off valves. Background technique [0002] Aircraft brake system is an important system to ensure aircraft safety. It is mainly used to dissipate the kinetic energy of the aircraft when taxiing on the ground, to ensure that the aircraft brakes to stop, shorten the taxi distance of the aircraft, prevent excessive wear of the wheels, and can cooperate with other airborne systems to realize the turning and parking functions of the aircraft. The important system for safe take-off and landing of aircraft is an important part of modern aircraft. [0003] At present, hydraulic brake systems are widely used in various types of aircraft due to their high power-to-mass ratio and high technological maturity. However, the hydraulic system's leakage, pipeline vibration, and hydraulic pipeline weight hinder its further ...
