STEERING GEAR OF WHEELED VEHICLE Russian patent published in 2003 - IPC

FIELD: transport engineering. SUBSTANCE: proposed steering gear of wheeled vehicle contains kinematically coupled steering wheel, steering mechanism, steering drive and distributor. Distributor, in its turn, is hydraulically connected with pump, tank and spaces of main power cylinder. Rod of main power cylinder is connected with steering drive, and two hole at both sides of piston are made in housing. Holes are made so that they are open when piston is in neutral position, and are closed in turn at displacement of piston. Spaces of main power cylinder are connected with corresponding spaces of additional power cylinder through these holes. Moreover, main and additional power cylinders have common rod, and housing of main power cylinder is made in of piston of additional power cylinder. Length of piston of main power cylinder is more than one third of length of its housing in which two additional channels are made connecting corresponding spaces of main power cylinder with distributor only in extreme positions of piston of additional power cylinder. EFFECT: compact design, reduced metal usage and improved arrangement on vehicle. 3 dwg
