Abstract
A track vehicle employing a rail track system attached to the sides of the frame of a track vehicle having a continuous track driven by pneumatic tires mounted to the frame proximate each end of the rail system along such that triangular torsion and compression links are mounted to the continuous track such that the apex end slides along the rail and the other ends extending against the track to provides lighter more even ground contact for use on snow and other soft terrain than present track vehicles.
Claims6
A track vehicle employing a rail track system comprising:
- a. a vehicle frame with cab adapted to support an operator,
- b. a pair of parallel side rails attached to each side of the vehicle frame,
- c. a pair of pneumatic drive tires with drive sprockets there between are rotatably attached to the frame via torsion bars proximate each end of the side rails such that the wheels extend below the vehicle frame,
- d. a continuous track with
- e. triangular torsion and compression links, each with an apex end adapted to push against and slide along the side rails and a pair of track ends affixed to the continuous track, are operably associated with the drive sprockets and surround the paired pneumatic drive tires such that the compression links pass between the drive tires while the track is driven by the pneumatic drive tires and drive sprockets, said torsion and compression links structured such that the apex end of the compression links push against and slide along the rails, and the track ends extend against the track to provide lighter more even ground contact with snow and soft terrain, and
- f. a drive motor attached to the frame and operably associated with the pneumatic drive tires and sprockets to drive the continuous track.
