The door and seat slide sideways (1)
by means of rams (2)
to enable entry and exit. The driver faces rearwards, steering by TV screen (3)
, showing forward view. In front of him are his instrument panel and control box (4)
which slides out to the most convenient position. (5)
is the selector panel and (6)
the hatch through which the power unit emerges. The driving position is duplicated on the right-hand side of the cabin.
The main, six-wheel drive is supplied by individual motors in each pair of wheels. Power is transmitted via the drive cogs (1)
through gearing (2)
. Magnetic breaks (3)
are similar to disc brakes but rely on magnetic forces, not friction. Rods (4)
make the smaller wheels track the front wheels which steer by hydropneumatic cylinders (5)
. The wheels are suspended on hydraulic shock absorbers (6)
which can also be used to retract the wheels for amphibious operation. Power is supplied to the wheel motors from the power unit (7)
. This works on fuel cell principles; that is the combination of air and the hydrogenic fuel generates electricity. The power unit stands on a ramp, held firm by twin clamps (8)
. This arrangement is used to present the power unit in the required position for other uses (see below). when the power unit is being used for other purposes the vehicle standby batteries (9)
drive the four sets of smaller wheels. At (10)
the caterpillar tracks are removed to show the internal drive motor and driving sprockets.
The power unit can also be used to power small personal vehicles. Here it is shown converted into a thruster pack, electrically driven high-speed compressors supplying air jets.
The various components are stored in the back of the vehicle in drawers (A)
. The appropriate ones are selected by using the panel (B)
. At (C)
is an emergency escape hatch.
When used amphibiously the wheels retract upwards and the flap (A)
closes. Propulsion is then by twin water turbo jets, positioned at the rear of the craft.
The incredible climbing position of the SPV is safer than it looks. The insert shows how the low centre of gravity (CG) of the vehicle is ahead of the rear tracks in the upright position. The vehicle thus has a built-in tendency to fall forwards rather than tip backwards.
