The present invention provides a power train for an amphibian operable in land and marine modes. The power train including a prime mover, a first land propulsion device, a first marine propulsion device, and a speed change transmission, wherein the prime mover is arranged to drive the first land propulsion device via the speed change transmission in land mode, and at least a portion of the prime mover is located between the speed change transmission and a rearward most part of the amphibian, with the speed change transmission located spaced ahead of the prime mover by a selected distance using one or more drive shaft(s).

This amphibious vehicle is provided with a body (11), a traveling device (12) that causes the body (11) to travel on land, a sailing device (13) that causes the body (11) to sail on water, a front flap (31) of which the distal end is inclined upward and the proximal end is rotatably supported by a horizontal shaft (34) on the front end of the body (11), a hydraulic damper (32) serving as a damping member that damps displacement of the front flap (31) relative to the body (11), and a compression coil spring (33) serving as a restoring member that restores the position of the front flap (31) relative to the body (11).

A mobile power station for the purpose of recharging electric vehicles is provided. The charging station includes separate, but different, types of electrical generation capabilities. For example, the charging station may include two or more of: wind power, solar power and power generated from oscillators, which charge its battery pack over land. If desired, the mobile power station can be amphibious, as well, and can navigate large bodies of water.

A boat is fitted with retractable wheels which can pivot between an extended land position and a retracted water position. A slot is formed in the hull of the boat. A housing sealing engages about the slot to prevent water entering the boat through the slot. The housing supports a pivot. An arm member is connected to the pivot and a wheel is connected to the arm member. The arm member can pivot through the slot between the wheel retracted and wheel extended positions.

An amphibious vehicle includes a vehicle body, a prime mover, a drive wheel, a water propulsion device, a drive wheel transmission, and a propulsion transmission. The drive wheel is disposed on a front side of the prime mover. The water propulsion device is disposed on a rear side of the prime mover. The drive wheel transmission is disposed on the front side of the prime mover and transmits power from the prime mover to the drive wheel. The propulsion transmission is disposed on the rear side of the prime mover and transmits the power from the prime mover to the water propulsion device.

An amphibious vehicle that includes a hull comprising a plurality of hull sections, a hull positioning device configured to position one of more hull sections from the plurality of hull sections into a plurality of positions, a first propulsion device configured to move the amphibious vehicle when the amphibious vehicle is on land, a second propulsion device configured to move the amphibious vehicle when the amphibious vehicle is in a body of water, and a buoyancy device configured to provide buoyancy for the amphibious vehicle when the amphibious vehicle is in the body of water.

Provided herein are a suspension apparatus and a specialized vehicle including the same. The suspension apparatus includes a crankshaft fixed to a vehicle body, a housing rotatably connected to the crankshaft, a first damping portion arranged in the housing and having a damping fluid accommodated in the first damping portion, an amount of the damping fluid in the first damping portion being adjusted according to an external force applied to the vehicle body, a second damping portion arranged in the housing, connected to the first damping portion such that the damping fluid moves between the first damping portion and the second damping portion, and including: a first space accommodating a compressed gas; and a second space accommodating the damping fluid, the first space facing the second space; and a rotational force applier arranged in the housing and configured to apply a rotational force to the housing by adjusting an amount of a working fluid in the rotational force applier.

An amphibious vehicle for operation in a liquid manure lagoon, the vehicle comprising: a floatable vehicle body; a ground engaging propulsion structure; a liquid manure pump for pumping liquid manure from the liquid manure lagoon; a power source for powering both the ground engaging propulsion structure and the liquid manure pump; and, a remote control structure for controlling the ground engaging propulsion structure, the liquid manure pump and the power source.

The present invention provides a power train for an amphibian operable in land and marine modes. The power train including a prime mover, a first land propulsion device, a first marine propulsion device, and a speed change transmission, wherein the prime mover is arranged to drive the first land propulsion device via the speed change transmission in land mode, and at least a portion of the prime mover is located between the speed change transmission and a rearward most part of the amphibian, with the speed change transmission located spaced ahead of the prime mover by a selected distance using one or more drive shaft(s).

A tracked, amphibious vehicle, comprising at least two, spaced, elongated pontoons disposed generally parallel to one another. A platform structure can be supported by and structurally connects the pontoons, the platform structure including a transom, a lowermost generally horizontally extending panel above a free clearance area under a bottom panel and between the pontoons through which terrain and debris can pass. A hydraulic drive system can propel the vehicle, said drive system including left and right hydraulic motors mounted on the pontoons. At least one series of longitudinally spaced bogie wheels for supporting said vehicle can be mounted along the bottom of the pontoons. A continuous, endless belt can encircle each pontoon and engages the bogie wheels. Ground-engaging cleats assembled on the outer surface of each belt and covering the pontoon bottom provide traction to the vehicle. Gearing interfaces the motor with the endless belts. A supplemental, marine drive assembly includes: a hydraulic motor having a rotary device, shaft, with an axis, a propeller shaft having an axis wherein the motor axis and propeller axis are aligned, a universal joint connecting the hydraulic motor to the transom, and a housing including a sleeve that contains the propeller shaft, a first vertical plate connected to the sleeve and a second vertical plate connected to the sleeve below the first plate.
