ABSTRACT:
Power train for an amphibious vehicle has an engine aligned with vehicle axis. The crankshaft drives optional flexible coupling, shaft, and optional decoupler. Drive shaft drives marine propulsion means, which may be a water jet drive or a screw propeller. Shaft also drives bevel gear, which drives transmission through bevel gear and input shaft. Hence, transmission is mounted transversely, and perpendicular to the engine. The bevel gears, coupling and decoupler are contained in a casing. Transmission drives road wheels through integral differential, drive shafts, and relay shaft. Transmission may be manual, sequential change manual, automated manual, automatic, or continuously variable transmission. The engine may be offset to the vehicle center line.
