Abstract
A track shoe assembly includes a pad portion, and a grouser that extends from the pad portion along a direction that is perpendicular to the pad portion, terminating at a free end. A first cap is attached to the grouser, at least partially covering the free end of the grouser. The cap comprises a wear resistant material such as a white iron material or a carbide material.
Claims20
A cladding member configured to be attached to a grouser of a track shoe, the cladding member comprising:
- a U-shaped body portion including:
- a first side wall,
- a second side wall, and
- a top wall connecting the first side wall to the second side wall and spacing the first side wall away from the second side wall along a direction that is parallel to the top wall a predetermined distance,
- the U-shaped body portion defining an overall height measured along a direction that is perpendicular to the top wall and an overall width that is measured along the direction that is parallel to the top wall, and
- the U-shaped body portion having a hardness that ranges from 55 HRC to 63 HRC;
- and
- a tip that extends from the top wall,
- the tip including an elongated projection that is integral with the U-shaped body portion, yielding a Y-shaped body,
- a side of the elongated projection facing a same direction as an end of the U-shaped body portion,
- the U-shaped body portion further defining an overall length that is measured along a direction that is perpendicular to the overall height and the overall width, and
- the side of the elongated projection being offset relative to the overall length, on the top wall, and away from the end of the U-shaped body portion.
