Definitions

  • the invention relates to a road clearing device in which a rotating body, to which at least one scraper bar is fastened, is rotatably mounted on a coulter body and is resiliently supported upwards and is supported in a torsionally elastic manner via at least one lever and one spring.
  • a rotating body on which two scraper bars are attached at an angular distance from one another, is mounted on a roller sector-shaped intermediate body, which in turn has a parallel to the rotating body and in Distance behind this pivot axis is pivotally mounted on the share body and is supported on the share body by a spring arranged at a distance from the pivot axis.
  • the rotating body is additionally supported by a toggle lever and a holding device on the intermediate body, and thus indirectly also on the share body.
  • the holding device enables the rotating body between the working positions of its two Swing scrapers back and forth.
  • a spring is built into the holding device, against the resistance of which the rotating body can perform a limited rotation if the working scraper bar gets caught on an obstacle.
  • the rotating body can deflect upwards by pivoting the intermediate body against the resistance of the spring acting on it.
  • the separation between the backward evasive movement of the working scraper bar made possible by a rotation of the rotating body and the upward evasive movement of the rotating body on the other hand has proven itself primarily because it makes it possible to oppose different evasive movements with different elastic restoring forces, so that the working scraper bar quickly and safely returns to its normal working position after overcoming an obstacle, regardless of whether it is a hard scraper bar that works with an angle of attack of approximately 90 ° or an elastic one that works with a pitch angle of, for example, 40 ° Scraper bar. It is therefore not necessary to lift the entire share body to enable the working scraper bar to return from an alternate position to its normal working position.
  • the invention is therefore based on the object to provide a road clearing device of the type described in the introduction, in which the proven functional separation between the rotatable and resiliently upwardly flexible mounting of the rotating body on the one hand and the torsionally elastic support of the rotating body on the other hand is realized in a particularly simple and reliable manner.
  • a bearing housing is arranged at each of its two ends, which has at least one elastomer body, a bearing journal rotatably mounted therein and at least one cavity for receiving the volume displaced by the bearing journal when the rotating body springs upward of the elastomer body encloses.
  • the invention has the advantage that upward impacts that act on the working scraper bar or directly on the rotating body are already absorbed by the elastomer bodies and largely absorbed by them, so that downstream components are no longer significantly burdened by such impacts.
  • the elastomer bodies at the two ends of the rotating body can deform to different extents and / or in different directions, so that the working scraper bar can always adapt well to the road surface.
  • the bearing housing Given the dimensions of the bearing housing, its interior can be divided into elastomer bodies and cavities in different ways, depending on whether the rotating body is working with an elastic scraper bar and should therefore be pressed against the road surface with only moderate force or whether he should work with a hard scraper bar and a correspondingly high contact pressure. Of all of this, the torsional elasticity of the rotating body remains essentially unaffected, because in a road clearing device of the type improved in accordance with the invention it depends essentially or exclusively on the lever-spring arrangement which supports the rotating body on the share body in a torsionally elastic manner.
  • the elastomer bodies are preferably also arranged in a resilient manner in the axial direction of the rotating body. This allows the additional advantage that the rotary body is also cushioned against axial or oblique impacts, such as occur, for example, when the working scraper bar grazes a curb without any significant additional construction effort.
  • the rotating body is hollow.
  • the cavity which is thus present anyway can be used according to the invention in that the elastomer bodies are arranged in the rotating body; in this case, the bearing housings are formed by the rotating body itself, which is open on its two end faces.
  • the elastomer bodies do not require any additional installation space; depending on the elastomer material used and depending on the desired spring hardness, the rotating body can be filled over a more or less large part of its length with the elastomer bodies in which the two associated bearing journals are mounted.
  • the bearing pins can be rigidly attached to the share body, so that the mass cushioned by the elastomer bodies is formed exclusively by the rotating body with one or two scraper bars attached to it.
  • the elastomer bodies are arranged in the rotating body and, in addition to their radial spring action, are to act as axially resilient, then they are expediently supported axially inwards on inner projections of the rotating body.
  • Arranging the elastomer body within the rotating body results in a particularly favorable spring action if the bearing pins are arranged eccentrically with respect to the cross section of the rotating body in such a way that their distance from the wall of the rotating body is greater than in the areas of the elastomer body that are subjected to pressure during clearing in their other areas.
  • the areas of the elastomeric bodies that are subjected to pressure during broaching have a radial thickness that is at least as large as the journal radius. This dimensioning is generally sufficient to allow the working scraper bar to roll over obstacles without noticeably lifting the share body.
  • an additional elastic alternative for the rotating body can be created in that the journals or the elastomer bodies are fastened to side cheeks which are pivotally supported on the share body against the resistance of additional elastomer bodies.
  • rotating body lever and spring are used in the singular in the foregoing, this does not mean that the use of several such components would be excluded. On the contrary, it is on most roads space devices advantageous to arrange two or more rotating bodies together with associated scraper bars in alignment with each other under a common coulter body and to support each of these rotating bodies in a torsionally elastic manner by means of their own lever with associated spring.
  • the road clearing device 10 shown in FIGS. 1 and 2, a snow plow, is connected to a vehicle 14, for example a truck, by a lifting device 12.
  • a vertical vehicle plate 16 is attached to the front side of the vehicle 14, which is detachably connected, for example, to a device plate 18 belonging to the lifting device 12 by means of screws, semi or fully automatic coupling devices.
  • the lifting device 12 includes parallelogram link 20 and a piston-cylinder unit 22, which connect a support body 24 of the road-clearing device 10 to the vehicle 14 so that it can be raised and lowered.
  • a coulter body 26 is mounted on the support body 24 so as to be pivotable about a vertical axis A.
  • the coulter body 26 includes a curved ploughshare 28 and crescent-shaped stiffening plates 30 arranged on its rear side in parallel vertical planes.

If, on the other hand, the elastic scraper bar 46 assumes its working position in which it faces the road surface B is inclined downwards by about 30 °, then the hard scraper bar 44 is directed obliquely backwards upwards.
  • Each of the rotating bodies 36 has an out-of-round and eccentric cross-section with respect to the bearing pins 40 such that it has a considerable distance from the lower edge of the ploughshare 28 in the working position of the hard scraper bar 44 according to FIGS. 1 and 2; this distance can be upward Federungsbewegun g s of the rotating body 36 to which are made possible by the elasticity of the elastomer body 42, the distance between the rotary body 36 and the lower edge of the plow blade 28 is bridged by the elastic scraper 46th In contrast, in the working position of the elastic scraper bar 46 there is only a barely noticeable distance between the rotating body 36 and the lower edge of the ploughshare 28, so that the material excavated by the elastic scraper bar 36 can easily flow into the ploughshare 28 over the rotating body 36.
  • An attachment 48 is welded to each of the two rotating bodies 36 behind the hard scraper bar 44, on which a toggle lever 50, which can be pivoted in a vertical plane, is supported with its front leg 52 by a front joint 54.
  • the front leg 52 of each of the two toggle levers 50 is connected by a knee joint 56 to a rear leg 58, which in turn is supported on a transmission lever 62 by a rear joint 60.
  • Each of the two transmission levers 62 is mounted on a pivot pin 64 parallel to the bearing pins 40 and axes of the joints 54 and 60 on one of the brackets 34.
  • the transmission levers 62 each have a long lower arm, at the lower end of which the joint 60 is arranged, and a short upper arm, which is directed forward angled and articulated at its front end to a tie rod 66.
  • the tie rod 66 extends vertically upwards through a recess in a stop 68, which is formed by a horizontal plate welded onto the bracket 34.
  • the stop 68 limits the swivel range of the upper arm of the transmission lever 62 upwards and thus also limits the swivel range of the lower arm of the transmission lever 62 to the front.
  • a spring 70 rests on the stop 68, which in the example shown is formed by a hollow body made of an elastomer.
