Abstract

Straßenfräsen verfügen über eine drehend antreibbare Fräswalze (11), die in einem Fräswalzenkasten (15) gelagert ist. Der Fräswalzenkasten (15) weist einen halbkreisförmigen Kastenmantel (19) zwischen zwei aufrechten Seitenwänden (20, 21) auf. Vor dem Kastenmantel (19) ist ein Niederhalter (25) auf- und abbewegbar angeordnet, der auf dem abzufräsenden Straßenbelag entlanggleitet und dafür sorgt, dass das abgefräste Straßenmaterial von der Fräswalze (11) zur Rückseite des Fräswalzenkastens (15) transportiert wird. Bei bekannten Straßenfräsen ist ein Niederhalter (25) ebenflächig ausgebildet, wodurch zwischen dem Niederhalter (25) und der Fräswalze (11) ein dreiecksförmiger Raum entsteht, in dem sich abgefräster Straßenbelag ansammelt, der separat beseitigt werden muss. Das ist arbeitsaufwändig. Deswegen schlägt die Erfindung vor, den Niederhalter (25) bogenförmig auszubilden, so dass er die Fräswalze (11) radial umgibt. Dadurch entsteht auch im Bereich des Niederhalters (25) ein schmaler Spaltraum. Das sich in diesem sammelnde abgefräste Straßenmaterial kann von der Fräswalze (11) abtransportiert werden zur Rückseite derselben, sodass vor der Fräswalze (11) kein abgefräster Straßenbelag liegen bleibt, der nachträglich entfernt werden muss.
