  • Patent number: 11820446
    Abstract: A ground-engaging track shoe includes a shoe plate having link-side fixturing surfaces and ground-side fixturing surfaces. The link-side fixturing surfaces and the ground-side fixturing surfaces are raised in profile relative to a link-facing surface and a ground-facing surface, respectively. The fixturing surfaces enable a fixture to clamp the track shoe for support during processing, enabling improvements in maintaining portions of the track shoe flat and reducing part to part variation.

  • Patent number: 11136078
    Abstract: In some examples, a shoe pad for a grouser of a vehicle track defines a slot configured to receive a bracket that is configured to attach the shoe pad to a grouser. For example, a first arm of a bracket may be inserted into the slot and a second arm of the bracket may be configured to contact an interior side of a grouser of a vehicle track to attach the shoe pad to the grouser. In some examples, the shoe pad and the bracket may be held to the grouser with the aid of a bolt, which bolt may not extend through the grouser, but, rather, may merely engage with an exterior side of the grouser. In this way, the shoe pad may be able to be attached to a grouser without requiring one or more holes to be present in the grouser, while still providing a relatively tight fit with the grouser the shoe pad is configured to cover.
