Abstract
A vehicle equipped with a 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.
Claims20
A vehicle comprising:
- a frame;
- a drive system including a drive sprocket operatively connected to an endless belt adapted to be rotated to propel the vehicle;
- a suspension system connected to the frame to suspend the frame, the suspension system including a plurality of independent driveless suspension modules longitudinally disposed at a distance from the drive sprocket, each suspension module comprising
- a pivot arm pivotally secured to the frame of the vehicle at a first end thereof about a pivot arm pivot and extending toward a rear portion of the vehicle to pivotally secure a first tandem member at a second end thereof about a first tandem member pivot;
- a first pair of idler wheels rotatably secured to a first end of the first tandem member;
- a second tandem member pivotally secured to a second end of the first tandem member thereof about a second tandem member pivot;
- a second pair of idler wheels rotatably secured to a first end of the second tandem member;
- a third pair of idler wheels rotatably secured to a second end of the second tandem member, the idler wheels being adapted to operatively secure thereon the endless belt;
- and
- a compressible suspension member operatively secured between the pivot arm and the frame to suspend the vehicle and adapted to absorb a load variation applied to the suspension system, the compressible suspension member being actuated when the pivot arm pivots about the pivot arm pivot.
