Abstract
The invention belongs to technical field of hydraulic pressure, are related to a kind of aircraft brake system, are mainly used in airplane brake system.Including airplane wheel, brake gear, pressure sensor, oil pipe, oil cylinder, piston, electric cylinder, controller, controller receives brake instruction, control electric cylinder output displacement to the left, it pushes piston to be moved to the left, makes the pressure rise of oil cylinder, pressure sensor is by the pressure feedback of output into controller, pass through closed-loop control, make oil cylinder output and the consistent brake pressure of brake instruction, the oil pressure of oil cylinder is input in brake gear by oil pipe, so that wheel be made to realize the purpose braked.The configuration of the present invention is simple, light-weight, high reliablity.
Description
Technical field
The invention belongs to technical field of hydraulic pressure, are related to a kind of aircraft brake system.
Background technique
World today's aircraft brake system is all a variety of using hydraulic oil container, hydraulic pump, oily filter, overflow valve, pressure reducing valve etc.
The oil supply system of Hydraulic Elements composition, gives Electric hydraulic pressure servo valve output order by controller, to be aircraft brake system
Export brake pressure.The Hydraulic Elements that this set of system not only uses are more, and price is high, and maintenance is complicated, and the event of each element
Barrier can all cause the failure of airplane brake system.And Electric hydraulic pressure servo valve is more demanding to oil cleanliness, in line
In often because oil contamination blocks, cause brake system failure.In addition, the brake system is formed using a variety of Hydraulic Elements,
Weight is big, to limit the use in light aerocraft, unmanned plane.
Summary of the invention
The purpose of the present invention: a kind of high reliablity, the simple aircraft brake system of structure are provided.
Technical solution of the present invention: a kind of aircraft brake system, which is characterized in that including wheel 1, brake gear 2, oil pipe
4, oil cylinder 5, piston 6, electric cylinder 7, controller 8；Brake gear 2 is installed on wheel 1, and brake gear 2 is connected by oil pipe 4
To the oil outlet of oil cylinder 5, for piston 6 in oil cylinder 5, the piston rod of piston 6 passes through pushing away for the circular hole connection electric cylinder 7 of oil cylinder 5
Bar, controller 8 connect electric cylinder 7.
The oil cylinder 5 is equipped with pressure sensor 3.
The piston 6 is equipped with sealing ring.
The controller 8 is driven by input power supply, brake instruction, pressure sensor signal to the output of electric cylinder 7
Dynamic signal.
Beneficial effects of the present invention: the present invention controls electric cylinder output displacement to the left by controller, pushes piston mobile,
The pressure rise for making oil cylinder, by increase pressure sensor by the pressure feedback of output into controller, by closed-loop control, make
Oil cylinder exports more accurate brake pressure.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention,
In figure: 1 be wheel, 2 be brake gear, 3 be pressure sensor, 4 be oil pipe, 5 be oil cylinder, 6 be piston, 7 be electricity
Dynamic cylinder, 8 are controllers.
Specific embodiment
The present invention will be further described in detail with reference to the accompanying drawing, as shown in Figure 1: a kind of aircraft brake system, packet
Power supply, brake instruction, pressure sensor signal and the controller 8 to electric cylinder output drive signal can be inputted by including, electricity
The push rod and piston 6 on dynamic 7 left side of cylinder connect, and for the piston 6 equipped with sealing ring in oil cylinder 5, pressure sensor 3 is mounted in oil cylinder 5
On, 4 one connection 5 one connection brake gears 2 of oil cylinder of oil pipe, brake gear 2 is mounted in wheel 1, which is characterized in that controller 8
Receive brake instruction, pushes piston 6 to be moved to the left by the push rod that output drive signal controls electric cylinder 7, make the pressure of oil cylinder 5
It increases, the pressure feedback of oil cylinder 5 into controller 8, by closed-loop control, refers to the output of oil cylinder 5 with brake by pressure sensor 3
Consistent brake pressure is enabled, the oil pressure of oil cylinder 5 is input in brake gear 2 by oil pipe 4, so that wheel 1 be made to realize braking
Purpose.
