STEERING GEAR (DESIGN VERSIONS) Russian patent published in 1999 - IPC

FIELD: transport engineering; vehicle steering systems. SUBSTANCE: proposed steering gear installed on vehicle has steering mechanism of any type or of gear- and-rack type set into action by steering shaft through gear wheel transmitting rotation to two eccentric or ellipsoidal gear or two gears one of which is eccentric or ellipsoidal, through gear racks arranged on two surfaces inclined in opposite directions according to one design version, or inclined surface for eccentric or ellipsoidal gear and surface parallel to axis of rack displacement for normal gear on other end of rack, according to other design version. Gears, in their turn, convey motion through their shafts to wheels by means of pitman arm, ball joints, rods and steering knuckle levers. EFFECT: provision of required difference in angles of wheel turning ensuring their rolling along circumferences without side slipping, irrespective of type of steering mechanism in use. 3 cl, 7 dwg
