Abstract: An endless track assembly for a track-type vehicle comprises an articulated chain for pivotally connecting each pair of adjacent track shoes together. Each articulated joint of the chain comprises a one-piece pin having a pair of laterally spaced pin portions and a bushing portion disposed intermediate the pin portions. A pair of first links are secured to the pin portions and a pair of second links are pivotally mounted on the pin portions. An annular seal is disposed between each adjacent pair of first and second links and a snap ring is secured to an outer end of each of the pin portions to prevent axial displacement of the links. A cavity is defined in the pin to communicate lubricant to the pivotal connections of the second links on the pin and end caps are secured on the ends of the pin to close the cavity and to cover the snap rings.

Abstract: A tensioning and recoil apparatus for the idler wheel and track of a crawler-type vehicle, such apparatus including a recoil spring and a hydraulic cylinder interposed between the spring and idler wheel. Hydraulic fluid is added to or released from the cylinder, as needed, to maintain a predetermined pressure level in the cylinder and a constant tension in the track trained around the idler and to provide a fluid damping of peak loads on the idler wheel and track during forward drive. Fluid is trapped in the cylinder when in reverse drive so that the cylinder then functions as a solid link between the recoil spring and idler wheel.
