ABSTRACT:
In the embodiment disclosed, the invention comprises a single, dual-piston cylinder, operable by hydraulic fluid, interpositioned between a pair of pivotably coupled, vehicular units. The cylinder is pivotably secured to pivot coupling elements which join the units, and each piston has its translating rod pivotably coupled to one of the units. Ports opening into the cylinder admit and discharge operating, pressured, hydraulic fluid (a) to displace the pistons apart, whereby a first crab steering is effected, (b) to move the pistons into mutual proximity, whereby a second, alternate crab steering is affected, (c) to displace the pistons in unison, in a first direction, whereby a left-hand or right-hand steering is effected, or (d) to displace the pistons in unison, in an opposite direction, whereby the opposite-handed steering is effected.
