The invention relates to a clearing strip (1) for the clearing blade of a snowplow, comprising a front steel plate (2) and a rear steel plate (3), which can be jointly fastened to the bottom edge of the clearing blade by means of fastening screws (9) and between which an elastic rubber body (5) is disposed, wherein at least one metal wear strip (6) is vulcanized into the rubber body (5), which metal wear strip protrudes out of the rubber body (5) downward toward the surface to be cleared (8) and has a clearing edge (7) which contacts the surface to be cleared (8). According to the invention, in order to ensure that the metal wear strip (6) is secured against release from the clearing strip (1) with minimal design complexity, and without loss of the elastic play of the wear strip (6) required for normal operation, corresponding fastening openings aligned with each other are provided in the steel plates (2, 3) and in the rubber body (5), which fastening openings are penetrated by fastening screws (9) for fastening the clearing strip (1) to the clearing blade, and the wear strip (6) is provided with securing cut-outs (10), through which the fastening screws (9) are fed and the inner peripheries of which leave distances from the outer peripheries of the fastening screws (9), which distances correspond to the maximum permissible elastic play of the wear strip (6) vulcanized into the rubber body (5).

The invention relates to a clearing strip (1) for the clearing blade of a snowplow comprising a securing collar (2) on which an elongate rubber element (4) is vulcanised, which has a freely bendable wear section (6) protruding downwards, a wear surface (7) and a wear height (8). The invention addresses the problem of overcoming, to the best possible extent, the trade-off between providing gentle, rapid and comprehensive clearing in areas of use that have extremely sensitive ground coverings, in particular airfields. To achieve this, the invention proposes the insertion of plastic gliding bodies (5) distributed over the wear portion (6).

The invention relates to a clearing strip (1) for the clearing shield of a snowplough, which clearing strip has a front steel plate (2) and a rear steel plate (4) between which an elastic rubber layer (5) with at least one hard material body (6) embedded in the rubber compound thereof is incorporated by vulcanization, wherein the hard material body (6) is movable relative to the steel plates (2, 4) with elastic deformation of the rubber compound. It is an object of the invention to develop the clearing strip of the type stated at the outset to the effect that the hard material bodies (6) embedded in the rubber compound are better secured against uncontrolled fall-out from the clearing strip (1) upon overheating. To achieve this object, the invention proposes that each individual hard material body (6) is anchored within the clearing strip (1) by means of an additional anchoring device, wherein this additional anchoring device does not limit the movability of the hard material bodies (6) relative to the steel plates (2, 4).

The invention relates to a screw connection for fastening an interchangeable kerb deflector (1) to a snowplough clearing strip (2) which is constructed as a composite body of a rubber layer (21) and steel layers (221, 222), wherein this screw connection has bores in the kerb deflector (1) and the snowplough clearing strip (2) which serve to receive a screw (31), and a separate threaded body (32) interacting with the thread of the screw (31). It is the object of the invention to develop a screw connection which firmly clamps the kerb deflector (1) to the snowplough clearing strip (2) and thus reduces the loading on the screw shaft and prevents the thread from being torn out. To achieve this object, the invention provides a screw connection of the initially stated type in which the threaded body (32) is designed as a body which can be inserted into the bore of the snowplough clearing strip (2) and which is supported on the steel layer (221) of the snowplough clearing strip (2) which is closest to the screw head (311), on which steel layer the kerb deflector (1) is also supported. Moreover, the invention relates to a method for detachable connection with a screw connection for fastening an interchangeable kerb deflector (1) to a snowplough clearing strip (2).
