ALL-WHEEL-DRIVE VEHICLE STEERING SYSTEM

摘要

mechanical engineering; agricultural tractors. SUBSTANCE: all-wheel-drive vehicle steering system has front steerable wheel steering linkage coupled with steering mechanism, rear steerable wheel steering linkage with hydraulic drive, drag-rod mechanically coupling front wheel steering linkage with rear wheel hydraulic drive. Front wheel steering linkage is provided with guide which couples the linkage with mechanism changing position of point of connection of front tie-rod to front wheel steering linkage. Steering linkage of front steerable wheels is provided with two levers rigidly connected to linkage and installed at distance from each other to provide possibility of action onto bell crank and rod coupled with spool of hydraulic distributor. EFFECT: improved stability of tractor at cornering. 2 dwg
