Definitions

  • the invention relates to a device for clearing snow from a roadway of a vehicle with at least one mouldboard and fastening means for fixing the device to the vehicle.
  • Such a device is for example from the CH 126 351 already known.
  • the snow remover shown there has two wedge-shaped mouldboards and is intended for mounting on a rail vehicle.
  • mats which are attached to high-speed rail vehicles. At high speeds, the device generates a bow wave on the high-speed vehicle, so that a maximum allowable pressure value is exceeded.
  • snow clearers used, which, however, the snow on the road is only insufficiently eliminated.
  • the object of the invention is therefore to provide a device of the type mentioned, which generates a bow wave, which is also at high speeds of the vehicle below an allowable maximum value, at the same time a sufficiently good clearing of the snow is provided by the roadway.
  • the invention solves this problem in that at least one mouldboard air outlets for reducing the air resistance is formed.
  • the device according to the invention has air outlets which reduce the air resistance of the device.
  • the air outlets are arranged according to the invention so that a sufficient clearance of the snow is possible.
  • the air-impermeable and the air-permeable portions of each mouldboard provide atomization of the powder snow and thus sufficient stripping from the roadway.
  • cardboard snow it comes through the air-impermeable portions when clearing to a thickening, the snow has a strength that allows each mouldboard despite the air passages to strip it from the road.
  • one or more mouldboard can be used.
  • the arrangement of the mats is basically arbitrary.
  • the air outlets are limited by Abstreifstege.
  • Such scraper bars are easy to produce and have a sufficiently high mechanical strength.
  • the device according to the invention has two mouldboard which are aligned wedge-shaped to each other, wherein the Abstreifstege are arranged on the opposite sides of the mouldboard.
  • the mouldboards are connected to each other in their converging side, so that a wedge tip is formed. Deviating from this, the mats limit an air gap, which allows the passage of snow in the central region of the device.
  • the stripping webs expediently extend in the longitudinal direction of the mouldboard and expediently extend inwards from the side of the respective mouldboard which is furthest outwards in a plan view.
  • the snow is thus detected by the inside, central and impermeable area of the mouldboard, transported to the outside and thereby thickened.
  • the thickened snow reaches the Abstreifstege whose distance is small enough to ensure stripping of the snow, wherein the air resistance is reduced due to the formed between the Abstreifstegen air passages, however.
  • the coating plates each form a first portion and a second portion, wherein the first portions with respect to the intersection of their imaginary longitudinal axes span a greater angle than the second portions with respect to the cutting point of their longitudinal axes.
  • the second sections are attached at an angle to the respectively assigned section.
  • the second sections are arranged sharper than the first sections. The device is thus less rapid in a plan view in width and forms a low air resistance.
  • the device 1 shown in the figure has a first mouldboard 2 and a second mouldboard 3.
  • the mouldboard 2, 3 has a first portion 2a and 3a, respectively, and a second portion 2b and 3b, wherein the first portions 2a, 3a are connected together to form a connecting edge 4 or ploughshare.
  • the mouldboard 2 and 3 are thus arranged wedge-shaped.
  • the connecting edge 4 engages under the snow while driving a rail vehicle, to which the device 1 is fastened in use, and splits it, the mats providing for stripping the snow from the road surface.
  • Each of the second sections 2b and 3b has scraper webs 5, which extend at the side facing away from the respective first section 2a or 3a side of the second portion 2b and 3b in the longitudinal direction, ie in the direction of travel, to the outside.
  • the wiper webs 5 delimit air outlets 6 which allow air to pass through the mouldboards 2, 3.
  • the second sections 2b and 3b are arranged at an angle with respect to the respective first section 2a or 3a.
  • the imaginary longitudinal axes of the second sections 2b and 3b clamp a smaller angle relative to their point of intersection than the imaginary longitudinal axes of the first sections 2a and 2a, respectively 3a with respect to its point of intersection, which here coincides with the connecting edge 4.
  • the second portions 2b and 3b, respectively are sharpened than the first portions 2a and 3a, respectively. This leads to a reduced air resistance, wherein the blunt arrangement of the first sections 2a, 3a provided a sufficiently high thickening of the snow, so that this despite the air outlets 6 can be safely removed from a roadway.
  • the size of the air outlets 6 is adapted to the degree of achievable compression of the snow. Falling through the snow through the air passages 6 can thus be largely excluded. At the same time the air resistance of the device 1 is reduced by the more pointed alignment of the second sections to each other.
  • fastening means comprising three holding units 8, 9 and 10.
  • the holding units 8 and 10 are connected at the free end of the mouldboard (2,3) fixed to the Abstreifstegen 5 and thus provide additional stabilization for the Abstreifstege 5 ready.
  • Each of the holding units 8, 9 and 10 has elongated holes 11 with which the device 1 is fastened to a vehicle and in particular to a rail vehicle. By aligning the slots 11 in the direction of travel, the vehicle and the device 1 are better protected against damage, since the holder of the device 1 on the vehicle can give something from a certain biasing force.
  • a height adjustment to compensate for a wheel wear is provided for example by vertical slots in the counterpart of the fastening units 8, 9 or 10.
  • the device is mounted as a snow eraser advantageously in the direction of travel before all axles lying down on the vehicle, so that the device while driving at a small distance on the road grazes.
  • Powder snow lying on a road surface is atomized and carried away by the air flow.
  • cardboard snow this is compressed by the first sections 2a and 3a in the middle part of the device 1, split in the middle and then slides laterally along the respective mouldboard 2 and 3 along. Due to the compression of the snow has become so strong that it can not be pushed through the air passages 6 through, but further slides to the outside.
