Abstract
There is a clearing strip for the clearing blade of a snowplow, comprising a front steel plate and a rear steel plate, which can be jointly fastened to the bottom edge of the clearing blade by means of fastening screws and between which an elastic rubber body is disposed. A metal wear strip is vulcanized into the rubber body, wherein the strip protrudes out of the rubber body downward toward the surface to be cleared and has a clearing edge which contacts the surface to be cleared. The strip is secured against release from the clearing strip with minimal design complexity, and without loss of the elastic play of the wear strip required for normal operation.
Claims4
A clearing strip for the clearing blade of a snowplow, comprising:
- an elastic rubber body (5);
- at least one metal wear strip (6)
- a plurality of steel plates comprising a front steel plate (2) and a rear steel plate (3), which can be jointly fastened to a bottom edge of the clearing blade by means of a plurality of fastening screws (9), and between which said elastic rubber body(5) is arranged, wherein said at least one metal wear strip (6) is vulcanized into the elastic rubber body (5), wherein said at least one metal wear strip (6) projects downward out of the elastic rubber body (5), toward a surface to be cleared, and has a clearing edge that touches the surface to be cleared,
- wherein
- corresponding fastening openings are arranged in said front steel plate(2), said rear steel plate (3) and the elastic rubber body (5), aligned with one another, through which said corresponding fastening openings said plurality of fastening screws (9) for fastening the clearing strip to the clearing blade pass, and wherein the elastic metal wear strip (6) is provided with a plurality of securing recesses (10) through which the plurality of fastening screws (9) are passed, and the inner circumferences of said plurality of securing recesses (10) leave spaces from the outer circumferences of the plurality of fastening screws (9), wherein said spaces correspond to a maximum permissible elastic movement play of the at least one metal wear strip (6) vulcanized into said elastic rubber body (5).
