Abstract
The present invention relates to a vehicle propulsion system. In an exemplary use described, the vehicle propulsion system is intended for a personal amphibious vehicle capable of efficiently transversing water, snow, land, ice and the like. In a preferred form, the vehicle propulsion system includes a pair of continuous belt tracks which are independently driven from a power plant.
Claims12
An amphibious personal vehicle, the vehicle comprising:
- a frame;
- first and second continuous belt tracks rotatably interconnected to said frame;
- a control arrangement for independently controlling each of said first and second continuous belt tracks;
- and
- a mounting bracket attached to said frame and a drive shaft rotatably supported by said bracket, said first and second continuous belt tracks rotatably supported by said drive shaft, said drive shaft being a split shaft having first and second ends rotatable at different speeds;
- both of said first and second continuous belt tracks including a belt portion and a plurality of blades, each blade of said plurality of blades oriented oblique with a reference line extending perpendicular to a longitudinal axis of an associated one of said first and second continuous belt tracks.
