Abstract
An amphibious passenger vehicle having several open or covered holes and a surrounding cover to accommodate fishing and hunting. An aft mounted engine, forward/reverse transmission, drive linkage and disk/caliper brake assembly controls a pair of rear wheels. Electric, screw actuated cylinders and pistons or manual linkage control the steering of a pair of forward wheels. Independent front and rear elevation control linkages independently control the elevation of the fore and aft wheels.
Claims21
A vehicle comprising:
- a) a chassis having a passenger compartment constructed to float and wherein a hole extends through a floor panel above a water line of the chassis;
- b) an engine;
- c) a plurality of wheels;
- d) a front suspension having a front axle mounted to a forward end of said chassis and supporting a front one of said wheels, wherein a front steering linkage is mounted to direct the travel direction of said front wheel, wherein a first reciprocating piston is mounted to rotate said front axle to raise and lower the front wheel parallel to a longitudinal axis of said body, and wherein a second reciprocating piston is coupled to direct said steering linkage;
- e) a rear suspension having a rear axle mounted to an aft end of said chassis and supporting a rear one of said wheels, wherein a third reciprocating piston is mounted to rotate said rear axle to raise and lower the rear wheel in a plane parallel to a longitudinal axis of said body and wherein said first, second and third reciprocating pistons each include an electrically actuated, screw drive assembly;
- f) a tiller arm mounted to said compartment and coupled to a brake means;
- and
- g) control means coupled to said first, second and third reciprocating pistons to direct the raising and lowering of said front and rear wheels.
