Abstract
A compactor wheel assembly includes a substantially cylindrical wheel surface having a plurality of compactor wheel tips extending radially therefrom. The wheel surface and the plurality of compactor wheel tips define an overall diameter. A plurality of arcuate shields are coupled with the wheel surface and define a substantially cylindrical wrapper around the wheel surface. The wrapper includes first and second bands. The first band has a diameter greater than the overall diameter and defines a substantially continuous surface for engaging the ground. The second band has a diameter less than the overall diameter and defines a substantially continuous surface for engaging the wheel surface.
Claims20
A compactor wheel assembly, comprising:
- a substantially cylindrical wheel surface having a plurality of compactor wheel tips extending radially therefrom, wherein the wheel surface and the compactor wheel tips define an overall diameter;
- and
- a plurality of arcuate shields coupled with the wheel surface and defining a substantially cylindrical wrapper around the wheel surface;
- wherein the wrapper includes first and second bands, the first band having a diameter greater than the overall diameter and defining a substantially continuous surface for engaging the ground, and the second band having a diameter less than the overall diameter and defining a substantially continuous surface for engaging the wheel surface;
- and
- the first band being offset from the second band such that the first band and the second band cover mutually exclusive portions of the wheel surface.
A compactor, including
- a frame;
- an internal combustion engine supported on the frame;
- a plurality of compactor wheel assemblies coupled through a drivetrain with the internal combustion engine, each of the plurality of compactor wheel assemblies including:
- a substantially cylindrical wheel surface having a plurality of compactor wheel tips extending radially therefrom, wherein the wheel surface and the compactor wheel tips define an overall diameter;
- and
- a plurality of arcuate shields coupled with the wheel surface and defining a substantially cylindrical wrapper around the wheel surface;
- wherein the wrapper includes first and second bands, the first band having a diameter greater than the overall diameter and defining a substantially continuous surface for engaging the ground, and the second band having a diameter less than the overall diameter and defining a substantially continuous surface for engaging the wheel surface;
- and
- the first band being offset from the second band such that the first band and the second band cover mutually exclusive portions of the wheel surface.
A compactor wheel shield assembly, comprising:
- a plurality of arcuate shields configured to be coupled with a substantially cylindrical wheel surface and to define a substantially cylindrical wrapper around the wheel surface, the wrapper including first and second bands;
- the first band having a diameter greater than an overall diameter defined by the wheel surface and a plurality of compactor wheel tips extending radially therefrom, and defining a substantially continuous surface for engaging the ground;
- the second band having a diameter less than the overall diameter and defining a substantially continuous surface for engaging the wheel surface;
- and
- the first band being offset from the second band such that the first band and the second band cover mutually exclusive portions of the wheel surface.
