Abstract

A drive train for an amphibious vehicle provided with a propellor disengaging mechanism aft of the transfer case, thus allowing the output drive shafts to be continuously driven at all times. The drive train includes a motor attached to a transmission which is attached to a transfer case. The attachments are accomplished by rotatably coupled drive shafts. The drive train transfers rotational movement from the motor to the transmission, then to a transfer case where it is output to the various drive shafts enabling the vehicle to be propelled on land and in water.

Independent Claims | See all claims (20)

  1. 1. A drive train for an amphibious vehicle having wheels capable of propelling the vehicle on land and a propeller capable of propelling the vehicle in water, the drive train comprising: a motor providing a rotary output; a transfer case selectively rotatably coupled with the motor and having at least one wheel drive output and a propeller drive output, wherein the propellor drive output is driven directly from inside the transfer case; and an engaging mechanism coupled with the motor and selectively movable by a vehicle operator between an engaged position and a disengaged position, wherein the motor rotates the propeller when the engaging mechanism is in the engaged position and wherein the motor does not rotate the propeller when the engaging mechanism is in the disengaged position.
  2. 10. A drive train for an amphibious vehicle having wheels capable of propelling the vehicle on land and a propellor capable of propelling the vehicle in water, the drive train comprising: a motor; a first drive shaft coupled with the motor; a transfer case coupled with the first drive shaft opposite the motor and having at least one wheel drive output and a propellor drive output, wherein the propellor drive output is driven directly from within the transfer case and wherein the first drive shaft provides a drive input to the transfer case; and an engaging mechanism located between the transfer case and the propellor, the engaging mechanism allowing a vehicle operator to selectively engage and disengage the propellor from the propellor drive output.
  3. 16. A drive train for an amphibious vehicle having wheels capable of propelling the vehicle on land and a propellor capable of propelling the vehicle in water, the drive train comprising: a motor; a first drive shaft coupled on one end with the motor; a transmission coupled with an end of the first drive shaft opposite the motor; a second drive shaft coupled on one end with the transmission; a transfer case coupled with an end of the second drive shaft opposite the transmission and having at least one wheel drive output and a propellor drive output; a third drive shaft coupled on one end with the propellor drive output of the transfer case for rotating the propellor; and an engaging mechanism located between the transmission and the propellor, the engaging mechanism allowing a vehicle operator to selectively engage and disengage the propellor from the motor.
