VEHICLE HYDROSTATIC STEERING GEAR Russian patent published in 2002 - IPC

FIELD: transport engineering; steering systems. SUBSTANCE: proposed steering gear has hydraulic cylinder whose housing is connected with steerable wheels pitman arm and rod is connected with pull-back spring by one of legs of legs of flexible element. Spaces of hydraulic cylinder are connected with proportioning pump mechanically coupled with pendulum through hydraulic distributor. With vehicle moving across slope and pendulum deflecting, proportioning pump provides delivery of working liquid into one of spaces of hydraulic cylinder in amount proportional to angle of pendulum deflection. As a result, steerable wheels are turned upwards along slope through and angle compensating for turning torque acting onto vehicle. EFFECT: facilitated steering, improved accuracy of straight-line motion of vehicle across slope. 1 dwg
