Abstract
A wheel-mounting assembly for a utility vehicle includes a chassis and a wheel support assembly mounted to respective outboard ends of first and second telescopic axle assemblies. The first and second telescopic axle assemblies are laterally spaced from one another and are each secured to the chassis. The first and second telescopic axle assemblies each include a respective actuator arranged to control extension and retraction thereof for steering and track-width control.
Claims19
A wheel-mounting assembly comprising:
- a wheel support assembly;
- a crank arm rigidly connected to the wheel support assembly;
- a first telescopic axle assembly coupled to the wheel support assembly by a link arm having a first end coupled to the first telescopic axle assembly by a first pivotable connection and a second, opposite end coupled to the wheel support assembly by a second pivotable connection;
- and
- a second telescopic axle assembly coupled directly to the crank arm by a third pivotable connection,
- wherein at least one of the first pivotable connection and the third pivotable connection comprises a clevis and pin connection, and
- wherein the first pivotable connection and the third pivotable connection are rotatable about axes of rotation that are parallel to each other.
