STEERING SYSTEM OF ALL-WHEEL-DRIVE VEHICLE Russian patent published in 2006 - IPC B62D7/14 

FIELD: mechanical engineering; agricultural engineering.

SUBSTANCE: invention can be used in farm tractors. Proposed steering system of all-wheel-drive vehicle has steering linkage of front steerable wheels coupled with steering mechanism of front steerable wheels, and steering linkage of rear steerable wheels with steering mechanism of rear steerable wheel drive. Steering mechanism of rear steerable wheel drive has shaft-screw and piston-rack which can move relative to shaft-screw. Engagement of rear steerable wheel drive mechanism is provided by electric motor, while its control is effected by shaft turning angle-into-digital code converter, with code processed by digital comparator of values. Time delay device - time relay is used to delay turning of rear steerable wheels.

EFFECT: improved stability in motion and maneuverability at cornering.
