Abstract
A work machine includes a drive wheel, a drivable track engaged with the drive wheel, a deformable spacer coupled to the drive wheel, and a secondary weight coupled to the deformable spacer. The deformable spacer facilitates oscillation of the secondary weight relative to the drive wheel to limit vibrations of the work machine.
Claims20
A work machine comprising:
- a drivable track;
- a drive wheel that is configured to rotate about an axis of rotation and is engaged with and configured to cause rotation of the drivable track;
- a retainer fixedly coupled to the drive wheel;
- an elastomeric spacer coupled to the retainer;
- and
- a secondary weight coupled to the elastomeric spacer;
- wherein the secondary weight is configured to rotate with the drive wheel about the axis of rotation.

5 more elements
A method for limiting the vibrations of a work machine comprising:
- rotating a drive wheel engaged with a drivable track, wherein the drivable track is disposed at a tension contributing to vibrations of the work machine;
- oscillating a secondary weight relative to the drive wheel to limit the vibrations of the work machine;
- wherein oscillating a secondary weight relative to the drive wheel includes deforming at least a portion of a deformable spacer coupled to the drive wheel and the secondary weight;
- and
- wherein deforming at least a portion of a deformable spacer coupled to the drive wheel and the secondary weight includes adjusting the viscosity of a fluid included in the deformable spacer based on the tension of the drivable track.
