Abstract:
1. An amphibious vehicle for a user in a sit-astride position, the vehicle comprising a power train, the power train including a prime mover having an output shaft, a continuously variable transmission having an input shaft defining an axis of rotation, a differential through which at least two road wheels of the vehicle are driven, and a marine propulsion unit, the prime mover being arranged for driving the marine propulsion unit, and for driving at least two road wheels of the vehicle through the continuously variable transmission and differential wherein the continuously variable transmission is mounted such that the axis of rotation of its input shaft is angled relative to a plane including both transverse and longitudinal axes of the vehicle, and the axis of rotation of the continuously variable transmission input shaft is also angled relative to the output shaft of the prime mover, wherein said continuously variable transmission has an output shaft defining an axis of rotation and wherein the axis of rotation of said continuously variable transmission output shaft is substantially parallel to the axis of rotation of said continuously variable transmission input shaft and wherein the differential has an input shaft driven from the output shaft of the continuously variable transmission, in which the axis of rotation of the input shaft is generally orthogonal to said plane.
