VEHICLE STEERING GEAR

transport engineering; cross- country vehicles; mechanical steering gears. SUBSTANCE: invention relates to vehicles furnished with electric steering servos and operating at maneuvering duties. Steering gear has steering wheel 1, steering mechanism 2, torque transmitter 3, electric motor 4, power amplifier 5, switch 6, comparator 7, current sensor 8, speed threshold setter 9, torque transmitter signal converter unit 10, current sensor signal converter unit 11, speed transmitter 12, logic first unit 13, adder 14, first control 15, logic second unit 16 and second control 17. Proposed steering gear increases response of vehicle steering gear electric servo and provides required reduction of torque on steering wheel at any angle of turning of steerable wheels at sufficient power output of installed electric motor. EFFECT: facilitated steering and maneuverability. 2 dwg
