Amphibious vehicle

An amphibious vehicle comprising:

• vehicle body:
• prime mover disposed in the vehicle body;
• drive wheel disposed on a front side of the prime mover;
• a water propulsion device disposed on a rear side of the prime mover;
• a drive wheel transmission disposed on the front side of the prime mover in the vehicle body and configured to transmit power from the prime mover to the drive wheel;
• a propulsion transmission disposed on the rear side of the prime mover in the vehicle a first power transmission shaft extending to the rear side from the prime mover and configured to transmit the power of the prime mover to the propulsion transmission;
• and a second power transmission shaft extending to the front side from the prime mover and configured to transmit the power from the prime mover to the drive wheel transmission, wherein the first power transmission shaft and the second power transmission shaft are disposed at central position in a lateral direction of the vehicle body.

An amphibious vehicle, comprising:

• a vehicle body;
• a prime mover disposed in the vehicle body;
• a drive wheel disposed on a front side of the prime mover;
• a water propulsion device disposed on a rear side of the prime mover;
• a drive wheel transmission disposed on the front side of the prime mover in the vehicle body and configured to transmit power from the prime mover to the drive wheel;
• and
• a propulsion transmission disposed on the rear side of the prime mover in the vehicle body and configured to transmit the power from the prime mover to the water propulsion device,
• wherein the propulsion transmission includes a power distribution unit that distributes the power from the prime mover between power to the drive wheel transmission and power to the water propulsion device, the amphibious vehicle further comprising:
• a first power transmission shaft extending to a rear side from the prime mover and configured to transmit the power of the prime mover to the propulsion transmission;
• and
• a second power transmission shaft extending to the front side from the power distribution unit and configured to transmit power for the drive wheel transmission from the power distribution unit to the drive wheel transmission, and
• wherein the prime mover includes an oil pan in which a lubricating oil for reducing friction in a sliding portion in the prime mover is stored, and
• the second power transmission shaft penetrates through the oil pan.
