Embodiment Construction

[0010] The present disclosure will be described in detail below in conjunction with the accompanying drawings.

[0011] figure 1 A block diagram schematically showing the structure of a redundant braking actuation system according to an embodiment of the present disclosure. The application in the aircraft anti-skid braking system is described below as an example. It should be understood that the redundant braking system according to the present disclosure can also be applied to other scenarios such as vehicle braking systems.

[0012] like figure 1 The shown aircraft anti-skid brake redundancy actuation system includes, for example, a brake trigger mechanism 1 of a brake pedal, an outer brake controller 21, an inner brake controller 22, a left outer brake control valve 31, a right outer brake control valve 34, a left outer brake control valve 34, a Inner brake control valve 32, right inner brake control valve 33, left outer wheel speed sensor 41, right outer wheel speed sen...

Abstract

The invention provides a braking redundancy actuating system. The system comprises a braking triggering mechanism, an outer side braking controller, left / right outer braking control valves, left / right outer machine wheel speed sensors, an inner side braking controller, left / right inner braking control valves and left / right inner machine wheel speed sensors. A braking instruction sensor installed on the braking triggering mechanism is electrically connected with the outer side braking controller and the inner side braking controller. The left inner braking control valve and the right inner braking control valve are electrically connected with the inner side braking controller. The left outer braking control valve and the right outer braking control valve are electrically connected with the outer side braking controller. The left inner machine wheel speed sensor and the right inner machine wheel speed sensor are electrically connected with the inner side braking controller. The left outer machine wheel speed sensor and the right outer machine wheel speed sensor are electrically connected with the outer side braking controller. A first system is adopted for supplying pressure to the left inner braking control valve and the right inner braking control valve, and a second system is adopted for supplying pressure to the left outer braking control valve and the right outer braking control valve. The outer side braking controller is electrically connected with the inner side braking controller. According to the braking redundancy actuating system, the normal anti-sliding braking function of the system is maintained, and the phenomenon that emergent braking is used, and the tire burst risk occurs is avoided.

Description

technical field [0001] The present disclosure relates to the field of brake control, in particular to a brake margin actuation system. Background technique [0002] Aircraft anti-skid braking system is an important airborne equipment, whether the system can work normally and its working stability will seriously affect the safety of the aircraft. Traditional aircraft anti-skid braking system usually adopts normal anti-skid braking system plus emergency braking system in system configuration. The way the system is used is as follows: when the normal anti-skid brake system fails, use the emergency brake to stop the aircraft. However, emergency brakes usually do not have an anti-skid function, and there is a risk of tires bursting during use. Contents of the invention [0003] The present disclosure aims to provide a brake redundancy actuation system that can be used in an aircraft anti-skid brake redundancy actuation system as well as any other similar scenarios such as a v...
