Description of the working
The A80 is a sweeper vehicle, exclusively designed for the cleaning of paved surfaces. The rubbish
in front of the vehicle is collected beneath the vehicle by two brushes. There it is sucked through the
suction mouth and transported to the rubbish hopper. The suction force in the suction mouth is
caused by under-pressure in the rubbish hopper. The fan on the rubbish hopper pumps the air out of
the rubbish hopper and releases it to the outside air through the air extraction duct in the top of the
rubbish hopper. A labyrinth inside changes the direction of the air stream several times, thereby
reducing the noise. The rubbish is moistened in the suction mouth so that it precipitates onto the
floor of the rubbish hopper and cannot be blown out again.
The power supply for all the motorized components of the sweeper vehicle is supplied by a
hydraulic system. This hydraulic system is in turn powered by the diesel engine. This type of power
supply ensures that the diesel engine can maintain a constant engine speed and that all other actions
(steering, linear, rotating) are generated by regulating the hydraulic fluid flow. For instance, the
driving action, the steering mechanism, the hydraulic cylinders, the sweeping unit and the suction
fan are all regulated hydraulically.
Only the driving speed and fan speed are directly affected by the reduced power and engine speed
of the diesel engine.
