Abstract
Amphibious vehicle power train includes an engine mounted above, or above and to one side of transmission. Axis of crankshaft is parallel to axis of transmission input shaft, and to longitudinal vehicle axis. Crankshaft longitudinally overlaps input shaft. Engine is mounted North-South, and transmission South-North. Crankshaft drives input shaft through sprockets, connected by belt or chain; or by gears. Shaft drives marine propulsion means through drive shaft and optional decoupler. Transmission may be manual, sequential change manual, automated manual, seem-automatic, automatic, or continuously variable. Power train may be mounted towards the rear of the vehicle, driving the rear wheels through differential. Alternatively, the front wheels may also be driven, through drive shaft and differential. Either axle may be decoupled in road mode.
