Abstract
In order that a road-sweeping machine with a chassis, with unsteered rear wheels and steered front wheels, with an engine which is disposed substantially above the rear wheels and drives them, with a seat near the engine and with a sweeping roller disposed on the underside of the chassis between the front and rear wheels at right angles to the direction of travel, and with a dirt collector, may be constructed in such a way that it has a compact construction of simple design and has a good sweeping effect whilst producing little dust, it is proposed that the dirt collector is disposed between the front and rear wheels adjacent to the sweeping roller and is connected by way of a suction line to a suction unit, and that the engine is disposed with the output shaft directed substantially vertically, the output shaft projecting upwards and downwards out of the engine, wherein the upwardly projecting portion thereof drives the suction unit and the downwardly projecting portion drives the rear wheels and the sweeping roller.
