Clearing strip for the clearing blade of a snowplow

Abstract

The invention relates to a clearing strip (1) for the clearing blade of a snowplow, having an attachment neck (2) onto which an elongated rubber body (4) is vulcanized, which body has a freely bendable wear section (6) that projects downward, having a wear surface (7) and a wear height (8). It is the goal of the invention to resolve the conflict of goals between gentle, rapid, and thorough clearing in areas of use having extremely sensitive ground coverings, in particular airfields, in the best possible manner. For this purpose, the invention proposes that plastic slide bodies (5) are inserted into the wear section (6), distributed over it.

1 . A clearing strip ( 1 ) for the clearing blade of a snowplow, having an attachment neck ( 2 ) onto which an elongated rubber body ( 4 ) is vulcanized, which body has a freely bendable wear section ( 6 ) that projects downward, having a wear surface ( 7 ) and a wear height ( 8 ),
 wherein   plastic slide bodies ( 5 ) are inserted into the wear section ( 6 ), distributed over it.   
     
     
         2 . The clearing strip ( 1 ) according to  claim 1 , wherein the wear surface ( 7 ) has a rubber surface component ( 7   a ) and a plastic surface component ( 7   b ) over at least 95% of the wear height ( 8 ). 
     
     
         3 . The clearing strip ( 1 ) according to  claim 2 , wherein ratio between plastic surface component ( 7   b ) and rubber surface component ( 7   a ) is coordinated between the two. 
     
     
         4 . The clearing strip ( 1 ) according to  claim 2 , wherein the ratio between the rubber surface component ( 7   a ) and the plastic surface component ( 7   b ) is essentially the same over the entire wear height ( 8 ). 
     
     
         5 . The clearing strip ( 1 ) according to  claim 2 , wherein the wear surface ( 7 ) has a sandwich-type structure having a front and a rear rubber surface component ( 7   a ) and a plastic surface component ( 7   b ) that lies between them. 
     
     
         6 . The clearing strip ( 1 ) according to  claim 2 , wherein the plastic surface component ( 7   b ) is arranged in the front in the direction of travel (F), and the rubber surface component ( 7   a ) is arranged in the rear in the direction of travel (F). 
     
     
         7 . The clearing strip ( 1 ) according to  claim 2 , wherein the plastic surface component ( 7   b ) is arranged in the rear in the direction of travel (F), and the rubber surface component ( 7   a ) is arranged in the front in the direction of travel (F). 
     
     
         8 . The clearing strip ( 1 ) according to  claim 1 , wherein the plastic slide bodies ( 5 ) are inserted into the rubber body ( 4 ) with shape fit. 
     
     
         9 . The clearing strip ( 1 ) according to  claim 1 , wherein the plastic slide bodies ( 5 ) have a block shape, triangular shape and/or cylindrical shape.
