VEHICLE HYDRAULIC STEERING GEAR Russian patent published in 2001 - IPC

FIELD: transport engineering; steering systems. SUBSTANCE: proposed hydraulic steering gear is designed for operation with priority device. It has feedback hydraulic motor, differential device, five-position spool distributor of continuous action with steering shaft and OR check valve with two inputs and one output providing connection of priority device control line with corresponding input of feedback hydraulic motor. Proposed hydraulic steering gear differs from steering gears of known design in the fact that with distributor in neutral position, control line in this position is connected with return line, and in extreme positions, control line is closed.
