Description

Die Erfindung betrifft eine Räumleiste für den Räumschild eines Schneepfluges, wobei die Räumleiste einen stählernen Befestigungshals und einen an dem Befestigungshals anvulkanisierten Gummikörper aufweist, der an seiner Außenseite durch Stahlplatten verstärkt ist, gemäß dem Oberbegriff des Anspruchs 1.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.

Räumleisten der angegebenen Art sind im Stand der Technik in verschiedenen Ausführungsformen bekannt. Die Außenseiten des Gummikörpers sind einseitig oder beidseitig mit großflächigen, starren Stahlplatten verstärkt. Probleme bei dieser Verstärkung des Gummikörpers mit einer starren Stahlfläche als Frontfläche entstehen jedoch dadurch, dass die Räumleiste bei Unebenheiten im Straßenbelag, wie z. B. Spurrillen oder mangelhaften Flickstellen infolge der inelastischen Stahlplatte entweder nicht gleichmäßig räumt oder Beschädigungen an diesen Objekten hervorruft. Im Stand der Technik sind daher z. B. in DE 29 04 251 C2 oder WO 94/17248 A1 Lösungen bekannt, welche nur für den unteren, mit der Straße in Kontakt stehenden Bereich des Gummikörpers eine Verstärkung durch Stahlplatten vorsehen. Oberhalb dieser Verstärkung können die angreifenden Kräfte in eine Verformung oder Biegung des Gummikörpers umgesetzt werden und somit die Ausweichbewegung der Räumleiste bewirken.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. However, 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. In the prior art are therefore z. In 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.

Nach wie vor bleibt jedoch bei Unregelmäßigkeiten im Straßenbelag das Problem, dass die für die Verformung des Gummikörpers aufzubringenden Kräfte und die für die schnelle Bewegung der schweren Stahlplatte zu überwindenden Massekräfte wesentlich größer sind als die von einem Hindernis entgegen gesetzten Kräfte. Dies führt unweigerlich zu einer Zerstörung des Hindernisses. Andererseits ist das Problem nicht gelöst, dass eine starre Stahlfront unregelmäßige Fahrbahnen, wie z. B. Fahrbahnen mit Spurrillen, nicht gleichmäßig räumt, weil sie nur an den höchsten Punkten der Oberfläche anliegt.As before, however, the problem remains with irregularities in the road surface that the forces to be applied for the deformation of the rubber body and the mass forces to be overcome for the rapid movement of the heavy steel plate are substantially greater than the forces opposing an obstacle. This inevitably leads to destruction of the obstacle. On the other hand, the problem is not solved that a rigid steel front irregular Lanes, such. B. lanes with ruts, not uniform clears, because it rests only at the highest points of the surface.

Es ist deshalb Aufgabe der Erfindung, eine Räumleiste zu schaffen, welche die Straße effektiv und gleichmäßig von Schnee und Eis räumt und gleichzeitig den Unebenheiten der Straße ohne Beschädigungen ausweicht bzw. folgt.It is therefore an object of the invention to provide a scraper, which clears the road effectively and evenly from snow and ice and at the same time evades the unevenness of the road without damage or follows.

Zur Lösung dieser Aufgabe schlägt die Erfindung ausgehend vom oben dargestellten Stand der Technik vor, dass die an der Außenfläche des Gummikörpers befestigten Stahlplatten in nebeneinander angeordnete, separate Stahlsegmente unterteilt sind, die gemeinsam eine einheitliche, bodennahe Räumkante bilden.To achieve this object, 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.

Durch die Nebeneinanderanordnung einzelner kleinerer Stahlsegmente wird die massive Stahlkante der Räumleiste durchbrochen. Somit kann sich jedes Stahlsegment flexibel und in gewissen Grenzen unabhängig von den anderen Segmenten bewegen, ohne dass bei dem Aufprall auf ein Hindernis die gesamte Räumleiste hoch- und/oder zurückgebogen werden muss. Dadurch reduzieren sich auch die zu überwindenden Massekräfte im Wesentlichen auf die Massekräfte der einzelnen Stahlsegmente.The juxtaposition of individual smaller steel segments, the massive steel edge of the scraper is broken. Thus, 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. As a result, the mass forces to be overcome are essentially reduced to the mass forces of the individual steel segments.

Zweckmäßig sind die Stahlsegmente an den Gummikörper anvulkanisiert. Hierdurch wird ein haltbarer Verbund zwischen den Stahlsegmenten und dem Gummikörper gewährleistet, so dass auch bei hoher Beanspruchung der Stahlsegmente diese nicht von der Räumleiste abfallen können und im schlimmsten Fall andere Verkehrsteilnehmer gefährden.Suitably, the steel segments are vulcanized to the rubber body. As a result, 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.

Die Erfindung sieht weiterhin vor, dass sich die Stahlsegmente an der Vorderseite und der Rückseite des Gummikörpers über dessen gesamte Höhe erstrecken und dass der stählerne Befestigungshals sich bis in den Bereich zwischen den vorderen und den hinteren Stahlsegmenten erstreckt und mit Abstand zu diesen in den Gummikörper einvulkanisiert ist. Diese Ausgestaltung erlaubt einen besonders stabilen Aufbau der Räumleiste und damit auch die Bewältigung schwerster Räumarbeiten. Durch eine möglichst vollumfängliche Bedeckung des Gummikörpers mit Stahlsegmenten sowie die Anordnung des Befestigungshalses bis in den Bereich zwischen den Stahlsegmenten kann ein großes Schneevolumen durch die Räumleiste geschoben werden, ohne dass sie einer Verformung außerhalb des elastischen Bereiches unterliegt und hierdurch Beschädigungen davonträgt.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.

Zweckmäßig ist der Gummikörper im Querschnitt rechtwinklig ausgebildet. Bezüglich der Herstellung ist dies die einfachste und kostengünstigste Variante.Suitably, the rubber body is formed at right angles in cross section. In terms of production, this is the simplest and least expensive variant.

Eine vorteilhafte Ausgestaltung der Räumleiste sieht vor, dass der Gummikörper im Querschnitt trapezförmig mit einem sich von oben nach unten erweiternden Querschnitt ist. Durch diese trapezförmige Erweiterung vergrößert sich das Volumen des Gummikörpers in Richtung der Räumkante. Dies führt insbesondere dort zu einer höheren Steifigkeit des Gummikörpers, wo die größte Schneemasse angreift, und zu einer geringeren Steifigkeit, wo die von den lokalen Hindernissen der Straßenoberfläche ausgehenden Kräfte angreifen.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.

Eine Ausführungsform der Erfindung sieht vor, dass der Gummikörper mindestens zwei Gummimischungen mit unterschiedlichen Härten aufweist. Zweckmäßig ist die Gummimischung in vertikaler Richtung bodennah härter als bodenabgewandt. Hierdurch lässt sich die Flexibilität der Räumleiste an die jeweilige Belastung anpassen. So z. B. ergibt sich durch eine härter Gummimischung in Bodennähe eine bessere Räumwirkung der Räumleiste. Denkbar ist ebenfalls eine kontinuierliche Zunahme der Härte über die Höhe der Räumleiste.An embodiment of the invention provides that the rubber body has at least two rubber compounds with different hardnesses. Appropriately, 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.

Im Sinne der Erfindung ist vorgesehen, dass der Gummikörper mindestens einen Hohlraum aufweist. Dieser Hohlraum oder auch mehrere einzelne Hohlräume dienen als Pufferraum für das verdrängte Material des Gummikörpers bei einem Aufprall auf ein Hindernis. Ebenfalls erleichtert ein Hohlraum die Verformung des Gummikörpers an der entsprechenden Stelle. Die Hohlräume können in jeder möglichen Anordnung innerhalb des Gummikörpers verwendet werden, wobei sich eine Anordnung besonders an den meist beanspruchten Stellen empfiehlt.For the purposes of the invention it is provided that 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. Also, 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.

Besonders empfehlenswert ist es, dass der Hohlraum in dem Gummikörper unterhalb der Unterkante des stählernen Befestigungshalses und parallel zu diesem verläuft. Der Bereich unter dem in den Gummikörper eingebetteten Befestigungshals ist in besonderem Maße Verformungen ausgesetzt. Durch diese Verformungen wird das Material des Gummikörpers verschoben, was zu einer lokalen Kompression führt. Wird nun genau dort ein Hohlraum platziert, kann das verdrängte, komprimierte Material entlastet werden.It is particularly recommended that the cavity in the rubber body below the lower edge of the steel mounting neck and parallel to this runs. The area under the mounting neck embedded in the rubber body 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.

Ebenso kann der mindestens eine Hohlraum in dem Gummikörper 4 auch vertikal verlaufen. Hierdurch kann die Steifigkeit der Räumleiste in horizontaler Richtung variiert werden.Likewise, the at least one cavity in the rubber body 4 can also run vertically. As a result, the rigidity of the scraper in the horizontal direction can be varied.

Zusätzlich empfiehlt es sich, dass der Hohlraum einen kreisrunden oder ovalen Querschnitt hat und sich über die gesamte Länge oder Höhe des Gummikörpers erstreckt. Die Erstreckung des Hohlraumes über die gesamte Länge gewährleistet dabei eine gleichmäßige Elastizität der Räumleiste. Die geometrische Querschnittsform eines Kreise oder Ovals ist zudem sehr stabil, da sie im Gegensatz zu beispielsweise einem Rechteck keine Ecken aufweist, welche bei Belastung schnell einreißen können.In addition, it is recommended that 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.

Eine besonders vorteilhafte Ausgestaltung des Hohlraums innerhalb der Räumleiste ergibt sich, wenn der Hohlraum von einem in den Gummikörper eingebetteten Schlauchabschnitt gebildet wird. Dies ist insbesondere in Bezug auf die Herstellung der Räumleiste vorteilhaft, da ein herkömmlicher Schlauchabschnitt in den Gummikörper mit eingegossen werden kann und somit eine nachträgliche Bearbeitung des Gummikörpers entfällt. Anderenfalls wäre es notwendig, nach dem Giessen des Gummikörpers Hohlräume in den Gummikörper zu bohren.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.

In Figur 1 und 2 ist schematisch eine Räumleiste dargestellt, welche an einem Befestigungshals 1 Durchgangslöcher 2 zur Anbringung an einen Räumschild eines Schneepfluges trägt. Eine bodennahe Räumkante der Räumleiste verfügt über mehrere nebeneinander angeordnete Stahlsegmente 3, welche an einen dahinterliegenden Gummikörper 4 anvulkanisiert sind. Figur 3 zeigt eine Seitenansicht der Räumleiste mit konischer Querschnittsfläche. In der Mitte der Räumleiste befindet sich der Befestigungshals 1, an welchen der Gummikörper 4 anvulkanisiert ist. Der Gummikörper 4 trägt an seiner Oberfläche die einzelnen Stahlsegmente 3. Innerhalb des Gummikörpers 4 ist ein schlauchförmiger Hohlraum 5 gezeigt, welcher die gesamte Breite des Gummikörpers 4 durchdringt. In Figur 4 ist die Seitenansicht einer Räumleiste mit rechteckiger Querschnittsfläche dargestellt.In 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. In the middle of the scraper is the mounting neck 1, to which the rubber body 4 is vulcanized. 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. In FIG. 4 is the side view of a clearing bar with rectangular cross-sectional area shown.

Die Erfindung funktioniert so, dass die Räumleiste mit Hilfe der Durchgangslöcher 2 an dem Räumschild eines Schneepfluges befestigt wird. Bei der Fortbewegung des Schneepfluges über eine Schnee bedeckte Fläche wird der Schnee gegen die Stahlsegmente 3 gedrückt. Bei einer gleichmäßigen Belastung der Räumleiste wird der Gummikörper 4 gleichmäßig nach oben und/oder nach hinten geschoben. In diesem Falle wird der innen in dem Gummikörper 4 liegende Schlauchabschnitt 5 gleichmäßig von dem verdrängten Material verformt.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.

Bei dem Auftreffen der Räumleiste auf ein kleineres, nur lokal vom Boden abstehendes Hindernis sind je nach der Größe des Hindernisses nur ein Stahlsegment 3 oder nur wenige mehrere Stahlsegmente 3 betroffen. Beim Auftreffen des Hindernisses auf jedes einzelne betroffene Stahlsegment 3 wird dieses zunächst mit dem dahinter liegenden Teilbereich des Gummikörpers 4 nach oben und/oder hinten gedrückt. Bei der Verformung des Gummikörpers 4 wird dabei der Hohlraum 5 zur Aufnahme des verdrängten Gummis 4 genutzt. Außer den unmittelbaren Nachbarsegmenten 3 bleiben die übrigen, weiter vom Hindernis entfernten Stahlsegmente 3, unbeeinflusst und können nach wie vor den Schnee von der Straße räumen.When hitting the clearing bar on a smaller, only locally projecting from the ground obstacle only one steel segment 3 or only a few steel segments 3 are affected depending on the size of the obstacle. When hitting the obstacle on each affected steel segment 3 this is first pressed with the underlying portion of the rubber body 4 up and / or back. In the deformation of the rubber body 4 while the cavity 5 is used to receive the displaced rubber 4. Apart from the immediate neighboring segments 3, the remaining steel segments 3, which are further away from the obstacle, remain unaffected and can still clear the snow off the road.

Im Falle einer mit Spurrillen überzogenen Fahrbahn dringen einzelne Stahlsegmente 3 mit dem dahinter liegenden Teilbereich des Gummikörpers 4 in die tiefer liegenden Bereiche der Straße ein, während die nicht betroffenen Stahlsegmente 3 auf der Höhe des übrigen Straßenbelags verbleiben.In the case of a track covered with ruts, individual steel segments 3 penetrate the underlying portion of the rubber body 4 into the lower regions of the road, while the unaffected steel segments 3 remain at the level of the remaining road surface.

Somit ist eine effektive Räumung einer Straße mit Höhenunterschieden der Oberfläche möglich.Thus, an effective clearance of a road with height differences of the surface is possible.
