Abstract
A mobile machine track shoe includes a ground engaging surface including a first grouser bar and a second grouser bar substantially parallel to the first grouser bar. The track shoe further includes a base opposite the ground engaging surface. The base includes a first relief disposed opposite the first grouser bar, and a second relief disposed opposite the second grouser bar.
Claims19
A mobile machine track shoe having a leading edge and a trailing edge, comprising:
- a ground engaging surface including:
- a substantially planar flat,
- a first grouser bar extending substantially perpendicular to the flat and substantially parallel to the leading and trailing edges, and
- a first curved portion disposed at the leading edge;
- and
- a base opposite the ground engaging surface, the base including:
- a first relief disposed opposite the first grouser bar, and
- a second curved portion disposed at the trailing edge, wherein the first relief has a depth measured from the base to the deepest portion of the relief that is less than a thickness of the track shoe measured from the base to the flat,
- wherein the first grouser bar has a first centerline and the first relief has a second centerline collinear with the first centerline.
A mobile machine track shoe having a leading edge and a trailing edge, comprising:
- a ground engaging surface including a substantially planar flat, a first grouser bar extending substantially perpendicular to the flat and substantially parallel to the leading and trailing edges, and a second grouser bar extending substantially parallel to the first grouser bar;
- and
- a base opposite the ground engaging surface, the base including a first relief disposed opposite the first grouser bar wherein the first relief has a depth measured from the base to the deepest portion of the relief that is less than a thickness of the track shoe measured from the base to the flat, and
- wherein the track shoe comprises steel having a carbon content greater than approximately 0.3%.
A track shoe for a mobile machine, comprising:
- a ground engaging surface including a first grouser bar, a second grouser bar substantially parallel to the first grouser bar, and a third grouser bar substantially parallel to the second grouser bar, wherein
- a combined width of the first, second, and third grouser bars comprises approximately one quarter of an overall length of the track shoe;
- and
- a base opposite the ground engaging surface, the base including a first relief and a second relief substantially parallel to the first relief,
- wherein a centerline of the first grouser bar is collinear with a centerline of the first relief and a centerline of the second grouser bar is collinear with a centerline of the second relief, and
- wherein the track shoe comprises steel having a carbon content greater than approximately 0.3% and further includes longitudinal grains formed in the microstructure of the steel.
