  • Patent number: 7520575
    Abstract: A tension management system for generating tension in an endless track of a tracked work machine. The tension management system comprises a biasing element, an idler wheel, a swing link, an idler arm, and a pivotal bracket linking the biasing element with the idler arm. The biasing element generates force that is translated via the biasing arm to the pivotal bracket. The pivotal bracket provides a mechanical advantage in the translation of the force that enables the force exerted upon the swing link to be greater than the force generated by the biasing element. The idler arm connects the pivotal bracket to the swing link and exerts force on the swing link causing it to pivot. The idler wheel is mounted on the swing link and exerts force, generating tension, in the endless track as the swing link pivots.

  • Patent number: 6273530
    Abstract: The adjustment mechanism of the present invention is mounted to a frame and comprises an alignment cam that is pivotally mounted to the frame by a tension link pivot pin. The alignment cam is provided with an actuating arm that is coupled to a longitudinally extendible adjusting member. The longitudinally extendible adjusting member comprising a screw jack. A tension link is pivotally mounted to the tension link pivot pin. Camming surfaces on the alignment cam are skewed with respect to the transverse axis defined by the tension link pivot pin so that rotation of the alignment cam twists the tension link and thereby the idler wheel predominately about a vertical axis. Albeit to a lesser degree, rotation of the alignment cam also twists the tension link and idler about a longitudinally extending horizontal axis. Therefore by extending or retracting the screw jack, the toe-in/toe-out orientation of the idler wheel can be adjusted.
