<p>Power train (30) for an amphibious vehicle (60, fig. 3) comprises engine (12) aligned with vehicle axis (32). The crankshaft drives optional flexible coupling (40), shaft (42), and optional decoupler (44). Drive shaft (46) drives marine propulsion means (48), which may be a water jet drive as shown, or a screw propeller. Shaft (42) also drives bevel gear (50), which drives transmission (14) through bevel gear (52) and input shaft (54). Hence, transmission (14) is mounted transversely, and perpendicular to the engine. The bevel gears, coupling (40) and decoupler (44) are contained in casing (53). Transmission (14) drives road wheels (34, 36) through integral differential (16), drive shafts (56 and 58), and relay shaft (21). Transmission (14) may be a manual, sequential change manual, automated manual, automatic, or continuously variable transmission. The engine may be offset to the vehicle centre line.</p> |
