Abstract
A clearing strip for the clearing blade of a snowplough has, in a sandwich design, a steel baseplate, a steel cover plate and an interposed rubber-elastic layer with at least one embedded hard material element. To better protect the embedded hard material elements from impacts without loss of clearing capability of the cleaning strip during continuous operation, at least one flexible buffer space is provided in the rubber-elastic layer above the hard material elements.
Claims9
A clearing strip (1) for the clearing blade of a snowplow, which strip has, in a sandwich design, a steel base plate (2), a steel cover plate (3), and a rubber-elastic layer (5) that lies between them, having at least one embedded hard-material element (6), whereby the steel base plate (2) and the steel cover plate (3) tightly seal the region above the hard-material elements (6) toward the outside in such a way that the rubber-elastic layer (5) cannot move upwards when the at least one embedded hard-material element moves,
- wherein
- at least one resilient buffer space (7) is provided in the rubber-elastic layer (5) above the hard-material elements (6).
