prototype DAF-139

|
The engine is placed in the centre of the vehicle
the occupants sit back to back :-)
There is room for 2 passagers and 2 drivers :-)
Yes indeed TWO drivers!
The steering in the back is locket under normal use but if necessary both the front and the back wheels can steer.
It is possible to reverse the direction from forward to reverse
and to steer the vehicle from the back position and still use al
the forward gears.

There is a extra gear reduction of 7.9:1
If you select the main revers gear and also select the revers gear on the normal gearbox
the vehicle will move forward with the extra reduction of the revers gear.

|
The extra gear reduction comes in handy when a very steep hill needs
to be climbed. The normal max incline is 27° (54%) but with the extra
reduction hills of 30° (60%) can be climbed.
The propeller is driven from the crown wheel of the rear differential so the wheels
are turning in the water.

The Dutch army tested the vehicle in march 1940 in the partly frozen
river "IJsel" and as far as is been known the vehicle preformed perfectly.
|
|
The vehicle was destroyed in May 1940 when
WW II broke out
to prevent it from falling in enemy hands.
