  • Publication number: 20050077784
    Abstract: A track for a tracked vehicle has a front idler wheel carried on a frame and a front double roller member carried on the frame construction rearward of the front idler wheel. The front idler wheel and the roller member are independently pivotally mounted on the frame by pivotal levers for upward and downward suspension movement in response to change in ground level. An actuating lever extends rearwardly from the front idler wheel over the pivotal lever of the double roller and a gas bag spring is located between the actuating lever and the double roller to absorb some upward movement of the front idler wheel so as to avoid transfer of a proportional downward movement to the roller member.
