Abstract
A work machine includes an undercarriage assembly. The undercarriage assembly includes a chassis and a ground-engaging mechanism for rotating around the chassis to move the work machine. A pair of rails is coupled to the chassis. A pair of sliders is coupled to a front-assembly. The sliders are aligned with the rails and movable relative to the rails to facilitate movement of the front-end assembly relative to the chassis.
Claims20
An undercarriage assembly for a work machine, comprising:
- a chassis extending from a forward end to an aft end;
- a ground-engaging mechanism configured to support the chassis;
- a front-end assembly movable axially relative to the chassis;
- an idler coupled to the front-end assembly at a rotational axis of the idler;
- a rail coupled to one of the chassis and the front-end assembly;
- and
- a slider having:
- a first end coupled to the other of the chassis and the front-end assembly, and
- a second end opposite the first end;
- wherein the rail includes a v-shaped groove defined by a pair of surfaces that diverge as the surfaces extend laterally toward an opening of the v-shaped groove;
- wherein the slider includes a pair of sides that converge as the sides extend from the first end to the second end of the slider;
- and
- wherein when the slider is positioned in the v-shaped groove of the rail, the slider is movable relative to the rail in axial and lateral directions.
