Abstract: A vehicle equipped with a double wishbones and double tandem members suspension system to suspend the vehicle, the double tandem members being operatively interconnected together and adapted to receive idling wheels adapted to support and guide an endless belt thereon to provide significant suspension travel and prevents an endless belt disengagement from the idling wheels. A suspension and a kit thereof are also provided.

Abstract: An endless belt tensioner system adapted to apply a tensioning force on a ground-contacting endless belt of a vehicle is provided, the tensioning force being substantially proportional to an endless belt drive force applied to the endless belt to move the vehicle. A vehicle and a method about the same are also provided.

Abstract: A suspension system adapted to receive an endless belt drive is provided, the suspension system comprising a first wishbone adapted to be secured at a first end thereof to a frame of a vehicle a second wishbone adapted to be secured at a first end thereof to the frame, a hub connecting the first wishbone and the second wishbone at second ends thereof, a tandem member pivotally secured to the hub, and at least one pair of wheels attached to the tandem member, the at least one pair of wheels being adapted to contact the endless belt to support the vehicle. A method of using same and a kit providing same are also provided.

Abstract: A vehicle frame comprises a structural portion of sheet material provided with a series of bents formed therein to increase the stiffness of the structural portion, portions of the sheet material being alternatively located on each side of a neutral flexion axis of the structural portion. A method and a kit providing same are also provided.
