Electrically controlled steering device for aircraft tractor

Abstract

The invention relates to an electrically controlled steering device for an aircraft tractor, relating to the aviation field of ground facilities. The electrically controlled steering device comprises a steering column and a steering wheel arranged thereon, and is characterized in that a coder and an arrester are installed on the steering column, a controller is used for collecting and outputting signals, and an angle sensor is installed on a steering axle; the steering wheel inputs analog signals into the controller by the coder, and the controller sends steering electric signals to a steering control electromagnetic valve according to the instruction of the obtained analog signals; after receiving the electric signals, the steering control electromagnetic valve controls a steering hydraulic cylinder to push the steering axle to act and to control the steering angle of the steering axle; and the angle sensor installed on the steering axle converts the collected actual steering angle of the steering axle into an electric signal and simultaneously inputs the electric signal into the arrester by the controller, and the arrester generates a relatively proportioned braking torque according to the obtained electric signal.

Description

technical field

[0001] The invention relates to the field of aviation ground facilities, in particular to an electronically controlled steering device for an aircraft tractor used for aircraft towing or pushing. Background technique

[0002] As we all know, the aircraft tractor works under the aircraft or bridge and adopts hydraulic steering gear. Therefore, it is required to leave enough space for the installation of hydraulic pipes in the cab of the aircraft tractor, and it is required that the hydraulic pipes should not be loosened. Space, so limit the cab space.

[0003] At present, the deadweight tonnage of aircraft used in civil aviation airports is increasing, and there are more and more airport service equipment and vehicles. The number of vehicles using hydraulic steering gears is increasing rapidly, and the leakage prevention of hydraulic steering gears is greatly restricted. The hydraulic steering gear of the aircraft tractor is required to have anti-leakage meas...
