METHOD TO CONTROL TURNING OF WHEELED VEHICLE WITH SIMULTANEOUS PARTIAL BRAKING OF ONE OF STEERABLE WHEELS Russian patent published in 1997 - IPC

FIELD: transport engineering; vehicle steering mechanism. SUBSTANCE: device has steering shaft 20 coupled through steering mechanism 1 with double-acting hydraulic cylinder 5, and brake cylinders 17 coupled with steering gear. Two-position three-line hydraulic distributor is installed at inlet of each brake cylinder of steerable wheel. First line of each hydraulic distributor is connected with double-acting hydraulic cylinder 5, second line is connected with brake master cylinder of standard brake system, and third line is connected with brake cylinder of steerable wheel. First line of each hydraulic distributor, when in first position, is connected with third line, and in second position, second line is connected with third line. Spaces of hydraulic distributor are interconnected through controllable pressure reducing valve which can be adjusted by changing pressure of its spring by means of adjusting screw mechanically coupled with steering shaft. EFFECT: enlarged operating capabilities, enhanced reliability. 2 dwg
