Schmutz zusammenführenden Kehreinrichtung.The invention relates to a self-propelled sweeper for cleaning drivable and/or walkable, preferably solid floor surfaces such as traffic areas, streets, airports and industrial plants, consisting of a chassis with a motor-driven axle and at least one wheel that can be steered together to influence the direction of travel, which aligned transversely to the direction of movement of the sweeper and are arranged spaced one behind the other, and with a refuse collection container built on the chassis and designed for emptying, for receiving refuse by means of a suction unit mounted on the chassis and having a suction fan, which is arranged with a suction air line at the front end Suction device is line-connected, whereby the suction device designed with a suction mouth is fastened to the chassis at a distance above the floor surface so that it projects downwards, as well as a driver's cab mounted on the chassis above the front axle and a driver's cab arranged below this, in front of the front axle, for the refuse to be picked up or Dirt-merging sweeping device.
Dabei wird die durch das Saugluftgebläse an der Ansaugeinrichtung resp. dem Saugmund erzeugte Saugluft/Saugkraft vom Kehrichtsammelbehälter nach Abscheidung des Schmutzes über eine Luftaustrittsleitung an die Umgebung zurückgeführt. Ist das Fahrgestell der Kehrmaschine ein- oder mehrteilig mit vier oder mehr Rädern ausgebildet, können die jeweils eine starre Vorderachse und/oder eine Hinterachse bildenden Räder paarweise gelenkt oder bei einer Knicklenkung, die Fahrachsen gemeinsam um senkrechte Achsen geschwenkt werden .In this case, the through the suction fan at the suction device, respectively.
