Definitions

  • the invention relates to a scraper for the snow blade of a snow plow, wherein the scraper has a steel mounting neck and a vulcanized on the mounting neck rubber body which is reinforced on its outside by steel plates, according to the preamble of claim 1.
  • Scrapers of the specified type are known in the prior art in various embodiments.
  • the outer sides of the rubber body are reinforced on one or both sides with large, rigid steel plates.
  • problems with this reinforcement of the rubber body with a rigid steel surface as a front surface arise from the fact that the scraper in case of unevenness in the road surface, such. B. ruts or poor patching due to the inelastic steel plate either does not evenly cleans or causes damage to these objects.
  • B. ruts or poor patching due to the inelastic steel plate either does not evenly cleans or causes damage to these objects.
  • In the prior art are therefore z.
  • DE 29 04 251 C2 or WO 94/17248 A1 Solutions are known which provide reinforcement by steel plates only for the lower, in contact with the road area of the rubber body. Above this gain, the attacking forces can be converted into a deformation or bending of the rubber body and thus cause the evasive movement of the scraper.
  • the invention proposes, starting from the above-described prior art, that the attached to the outer surface of the rubber body steel plates are divided into juxtaposed, separate steel segments, which together form a uniform, ground-level reaming edge.
  • each steel segment can move flexibly and within certain limits independently of the other segments, without the entire clearing bar having to be bent up and / or back in the event of an impact on an obstacle.
  • the mass forces to be overcome are essentially reduced to the mass forces of the individual steel segments.
  • the steel segments are vulcanized to the rubber body.
  • a durable bond between the steel segments and the rubber body is guaranteed, so that even at high stress of steel segments they can not fall off the scraper and endanger other road users in the worst case.
  • the invention further provides that the steel segments at the front and the back of the rubber body extend over its entire height and that the steel mounting neck extends into the region between the front and the rear steel segments and vulcanized at a distance from these in the rubber body is.
  • This embodiment allows a particularly stable construction of the scraper and thus also the management of the heaviest clearing work. By covering as fully as possible the rubber body with steel segments and the arrangement of Attachment neck to the area between the steel segments, a large volume of snow can be pushed through the scraper, without that it is subject to deformation outside the elastic region and thereby causes damage.
  • the rubber body is formed at right angles in cross section. In terms of production, this is the simplest and least expensive variant.
  • An advantageous embodiment of the scraper provides that the rubber body is trapezoidal in cross-section with a widening from top to bottom cross-section. This trapezoidal enlargement increases the volume of the rubber body in the direction of the reaming edge. This leads in particular to a higher stiffness of the rubber body, where the largest mass of snow attacks, and to a lower rigidity, where attack from the local obstacles of the road surface forces attack.
  • the rubber body has at least two rubber compounds with different hardnesses.
  • the rubber compound in the vertical direction is near the ground harder than the ground. This allows the flexibility of the scraper to adapt to the particular load. So z. B. results from a harder rubber compound near the bottom, a better clearing action of the scraper. Also conceivable is a continuous increase in hardness over the height of the scraper.
  • the rubber body has at least one cavity.
  • This cavity or several individual cavities serve as a buffer space for the displaced material of the rubber body in an impact on an obstacle.
  • a cavity facilitates deformation of the rubber body at the appropriate location.
  • the cavities can be used in any possible arrangement within the rubber body, with an arrangement especially recommended in the most stressed places.
  • the cavity in the rubber body below the lower edge of the steel mounting neck and parallel to this runs is subjected to particular deformation. These deformations displace the material of the rubber body, causing local compression. If a cavity is placed right there, the displaced, compressed material can be relieved.
  • the at least one cavity in the rubber body 4 can also run vertically.
  • the rigidity of the scraper in the horizontal direction can be varied.
  • the cavity has a circular or oval cross section and extends over the entire length or height of the rubber body.
  • the extension of the cavity over the entire length ensures a uniform elasticity of the scraper.
  • the geometric cross-sectional shape of a circle or oval is also very stable, since it has no corners in contrast to, for example, a rectangle, which can tear quickly under load.
  • a particularly advantageous embodiment of the cavity within the scraper results when the cavity is formed by an embedded in the rubber body tube section. This is particularly advantageous in relation to the production of the scraper, since a conventional tube section can be molded into the rubber body and thus eliminates subsequent processing of the rubber body. Otherwise, it would be necessary to drill cavities into the rubber body after casting the rubber body.
  • FIG. 1 and 2 schematically a scraper is shown, which carries on a mounting neck 1 through holes 2 for attachment to a plow blade of a snow plow.
  • a ground-flush edge of the scraper has a plurality of juxtaposed steel segments 3, which are vulcanized to a rubber body 4 lying behind it.
  • FIG. 3 shows a side view of the scraper with a conical cross-sectional area.
  • the rubber body 4 carries on its surface the individual steel segments 3.
  • Within the rubber body 4 a tubular cavity 5 is shown, which penetrates the entire width of the rubber body 4.
  • FIG. 4 is the side view of a clearing bar with rectangular cross-sectional area shown.
  • the invention works by attaching the scraper blade to the plow blade of a snowplough using the through holes 2. As the snow plow moves along a snow-covered surface, the snow is pressed against the steel segments 3. With a uniform load on the scraping the rubber body 4 is pushed evenly upwards and / or to the rear. In this case, the inside of the rubber body 4 lying in the tube section 5 is uniformly deformed by the displaced material.
