  • Publication number: 20230340740
    Abstract: Disclosed 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.

  • Patent number: 11773551
    Abstract: A clearing strip for the clearing shield of a snow plow has a front steel plate and a rear steel plate between which an elastic rubber layer with at least one hard material body embedded in the rubber compound thereof is incorporated by vulcanization. The hard material body is movable relative to the steel plates with elastic deformation of the rubber compound. To better secure the hard material bodies embedded in the rubber compound against uncontrolled fall-out from the clearing strip upon overheating, each individual hard material body is anchored within the clearing strip by an additional anchoring device that does not limit the movability of the hard material bodies relative to the steel plates.

  • Publication number: 20210381182
    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.

  • Patent number: 10947686
    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.

  • Patent number: 10557237
    Abstract: A curbstone deflector for protection of the lateral end region of a snow-clearing strip attached to a snowplow clearing blade has a round or polygonally rounded-off wear edge and a recess that surrounds the end region of the snow-clearing strip, which recess has a front support surface supported on the front side of the snow-clearing strip from the front, and a lateral support surface supported on the side edge of the snow-clearing strip from the side, wherein the front support surface can be braced against the front side of the snow-clearing strip via a screw connection. The expanse of the front support surface in the longitudinal direction of the snow-clearing strip is greater by at least 1.2 times, preferably by 1.5 times than the distance between the lateral support surface and the wear edge of the curbstone deflector.

  • Patent number: 10392762
    Abstract: A snow-clearing strip for the snow-clearing blade of a snowplow has an attachment neck, onto which an elongated rubber body is vulcanized, which body has a wear section that projects downward and is freely flexible, and in which hard-material wear bodies are embedded over the wear height. A reinforcement is attached to the attachment neck, which reinforcement extends over at least the upper third of the wear height and is connected with the rubber body with material bonding.

  • Publication number: 20190078279
    Abstract: The invention relates to a snow-clearing strip (1) for the snow-clearing blade of a snowplow, having an attachment neck (2), onto which an elongated rubber body (3) is vulcanized, which body has a wear section (3a) that projects downward and is freely flexible, and in which hard-material wear bodies are embedded over the wear height (H). It is the task of the invention to improve the wear resistance of snow-clearing strips of the type stated initially, to the effect that these are better suitable for use at high snow-clearing speeds and/or in the case of uneven surfaces to be cleared, and achieve longer useful lifetimes. To accomplish this task, the invention proposes that a reinforcement is attached to the attachment neck (2), which reinforcement-extends over at least the upper third of the wear height (H) and is connected with the rubber body (3) with material bonding.

  • Patent number: 8640365
    Abstract: The invention relates to a clearing strip for the blade of a snowplow, the clearing strip having a steel fastening neck (1) and a rubber body (4) which is vulcanized onto the fastening neck (1) and is reinforced on its outer face by steel plates. The outer faces of the rubber body (4) are reinforced by means of large surface-area, rigid steel plates either on one side or on both sides. The steel plates fastened to the outer surface of the rubber body (4) are divided into separate steel segments (3) that are arranged adjacent each other and together form a uniform clearing edge close to the ground.

  • Patent number: 7765726
    Abstract: The invention relates to a sandwich scraper strip for the blade of a snowplow and provided at the top with a steel fastening neck onto which a rubber body having at least one embedded hard material body is molded. According to the invention, the hard material body is provided in the form of a hard metal core surrounded by a steel jacket. This results in achieving a surprisingly high serviceable life of the sandwich scraper blade.
