Truck with Large Cargo Bed
Undercover Technology
This truck has command of a pure chain drive that
turns the wheels on the rear axle. The unusual thing
about it is that the transmission to the rear axle is
practically invisible. Only the chain from the engine
to the drive shaft is visible — the other chains are
hidden by the large cargo bed. The big headlights on
the front grill turn when the truck is moving. They are
set in motion by the front wheels, and have no direct
contact with the engine. The yellow gear wheels move
in reverse of the vehicle’s motion: while the truck is
driving forward, they turn in the opposite direction.
Another special feature is the vehicle’s moveable front
end.
On this truck with a big cargo bed, it isn’t just the tires that turn: The gear wheels on the front grill are also rotated by the front axle.
