  • Track block
    Patent number: 4435022
    Abstract: A track block for a track-laying vehicle. The block is characterized by an elongated unitary beam, with two diverging links extending radially in a common direction from opposite ends of the beam. The links are constructed to straddle, and to be hinged to, the beam in an adjacent block. Cantilevered from a central portion of the beam, and extending generally in the same direction as and coplanar with the links, is a road-wheel bearing plate, through which received road-wheel bearing forces are carried directly to the links solely through the beam.
