Abstract
A tie rod extendable and retractable telescopic axle assembly wherein a pair of axle beams are slidably mounted in a box beam integral with a vehicle chassis. Steering linkage and associated wheel assemblies are mounted on the outer ends of the axle beams, and the inner ends of the axle beam within the box beam are telescopically mounted relative to each other which provides an increased wheel base when the axle beam are moved outwardly of the box beam. A hydraulic cylinder and piston rod assembly is mounted between the box beam and wheel assemblies so that the hydraulic cylinder and rod assembly function not only as an actuator for extending and retracting the axle beams but also as a tie rod for the wheel assemblies.
