AIRCRAFT LANDING GEAR WHEEL BRAKING SYSTEM Russian patent published in 1998 - IPC

FIELD: aeronautical engineering. SUBSTANCE: electrohydraulic unit used for forming the braking pressure is located in zone of wheel and is provided with variable-capacity pump 5 connected with revolving part of wheel 3 by means of gear train. 7. Pump 5 controlled by means of electrohydraulic booster 9 provided with power cylinder 8 delivers pressure to braking cylinders 11. Pressure control is effected by means of control and monitoring unit 15 by signals of setter 2 connected with braking pedal 1 taking into account signal from pressure feedback sensor 10 and wheel speed sensor 14. Pump 5 is filled with working fluid from hydraulic compensator 12 fitted with manually-controlled safety valve 13 for bleeding air in filling the system. EFFECT: enhanced efficiency. 5 cl, 1 dwg
