STEERABLE WHEEL MODULE WITH STEERABLE WHEEL ALIGNMENT ANGLES Russian patent published in 2002 - IPC

FIELD: transport engineering; steering gears of wheeled vehicles. SUBSTANCE: steerable wheel module has steerable wheels installed on steering knuckles which are hinge- mounted by means of kingpins on beam and connected by means of two steering knuckle arms and hinge joints with split tie-rod. Split tie-rod, in its turn, is made for adjusting its length by turning coupling nut with left- hand and right-hand inner thread from different sides. Moreover, steerable wheel module is furnished additionally with two single-action power cylinders. Housing of one of power cylinders is secured on split tie-rod for displacement along its axis being hydraulic coupled through restrictor with energy accumulator and second power cylinder. Piston of second power cylinder is connected with sprung mass, and housing, with sprung mass of wheeled vehicle. Piston of first power cylinder is mechanically coupled with coupling nut and is made in form of two movable spring-loaded blades installed in longitudinal slots on outer surface of coupling nut. Its housing is made in form of hermetically sealed cylinder accommodating two fixed spring-loaded blades in contact with outer surface of coupling nut placed inside and forming, together with movable spring-loaded blades, two working spaces of power cylinder. Coupling nut and housing of first power cylinder are interconnected by pull-back spring precluding their rotation relative to each other. EFFECT: enlarged operating capabilities. 2 cl, 3 dwg
