The invention is directed to a hydraulic tensioning and suspension system having a main drive wheel located above and between two idlers that are mounted to pivot arms that are coupled to a rigid frame. In addition, two track rollers are mounted to the rigid frame by an intermediate arm and a third track roller is mounted to the front pivot arm by an additional pivot arm. Four hydraulic suspension cylinders are hydraulically coupled to one another for biassing the idlers and track rollers downwardly to provide a suspension system. The rear pivot arm is a...
An undercarriage for a tracked vehicle comprising: a rigid frame; a main drive wheel mounted to and extending outward from the rigid frame, the main drive wheel having a main drive wheel axis; a front pivot arm is pivotally coupled to the rigid frame; a front idler is rotatably coupled to the front pivot arm, the front idler having a front idler axis; a front hydraulic suspension cylinder is mounted between the rigid frame and the front pivot arm for biasing the front pivot arm downwardly; a rear pivot arm is pivotally coupled to the rigid frame, the rea...
