ELECTROHYDRAULIC MULTICHANNEL STEERING GEAR

摘要

FIELD: steering gears; applicable in systems of automatic control of flying vehicles. SUBSTANCE: steering gear has in each channel electrohydraulic power amplifier communicated hydraulically via slide valve of switching-cross feeding controlled by electromagnetic valve with power source, with respective chambers of hydraulic cylinder of multichannel servosteering machine and with hydromechanical correcting device with position pickup. In this case, rod of multichannel servosteering machine is connected with feedback transducer and with two-system slide-valve hydraulic distributing device which is connected with power source and with corresponding chambers of two-chamber ram whose rod is connected with feedback transducer unit. Hydromechanical correcting device consists of correction slide valve and correction hydraulic cylinder interconnected with each other by hydraulic lines. In this case, rods of correction hydraulic cylinders of each channel are not connected with each other. EFFECT: higher reliability. 5 cl, 3 dwg
