Description

Die gegenständliche Erfindung betrifft einen Schneepflug mit einem an ein Tragfahrzeug ankuppelbaren Traggestell für eine Pflugschar, welche mittels mindestens einer Stelleinrichtung gegenüber dem Traggestell für die Pflugschar verschwenkbar ist, wobei die Pflugschar ein Traggestell für eine Scharplatte und die an diesem befestigte, aus einem hartelastischen Material, insbesondere Hartgummi, hergestellte Scharplatte aufweist und weiters das Traggestell für die Scharplatte zumindest zwei miteinander gelenkig verbundene Teile aufweist, welche um eine in der Betriebslage der Pflugschar zumindest angenähert vertikale Achse gegeneinander verschwenkbar sind, wie z.B. aus US 4 356 645 bekannt. Bekannte Schneepflüge sind mit einem Traggestell für eine Pflugschar ausgebildet, welches an ein Tragfahrzeug ankuppelbar ist, wobei es durch Verschwenkung mittels einer am Tragfahrzeug befindlichen Hydraulikanlage einerseits in eine Hochlage anhebbar ist, um den Schneepflug zu einem Einsatzort transportieren zu können, und andererseits am Einsatzort in die Betriebslage absenkbar ist, wodurch die untere Kante der Pflugschar an eine Bodenfläche, welche von Schnee bzw. Eis geräumt werden soll, zur Anlage kommt.The subject invention relates to a snowplough with an attachable to a support vehicle support frame for a ploughshare, which is pivotable by means of at least one adjusting device relative to the support frame for the ploughshare, the ploughshare a support frame for a share plate and attached to this, made of a hard elastic material, in particular hard rubber, produced share plate and further comprises the support frame for the share plate at least two mutually articulated parts which are pivotable about a in the operating position of the ploughshare at least approximately vertical axis against each other, such as from US 4,356,645 known. Known snowploughs are formed with a support frame for a ploughshare which can be coupled to a support vehicle, wherein it can be raised by pivoting means of a hydraulic vehicle located on the support vehicle on the one hand in a high position to transport the snowplough to a job site, and on the other hand at the site in the operating position is lowered, whereby the lower edge of the ploughshare to a floor surface, which is to be cleared of snow or ice, comes to rest.

Weiters ist die Pflugschar am Traggestell um eine angenähert vertikale Achse verschwenkbar gelagert und ist am Traggestell zumindest eine Stelleinrichtung, insbesondere mindestens ein Hydraulikzylinder, vorgesehen, durch welche die Pflugschar in beliebige Winkellagen dem Traggestell bzw. gegenüber der Fahrtrichtung verstellbar ist.Furthermore, the ploughshare on the support frame is pivotally mounted about an approximately vertical axis and is provided on the support frame at least one adjusting device, in particular at least one hydraulic cylinder, through which the ploughshare in any angular positions of the support frame or against the direction of travel is adjustable.

Beim Betrieb von Schneepflügen, welche über Bodenflächen verfahren werden, besteht die Schwierigkeit, dass sich in den Bodenflächen Hindernisse, wie Randsteine, Pflastersteine, Kanaldeckel u.dgl., befinden können, auf welche die Pflugschar auffährt, wodurch die Pflugschar insbesondere im Bereich der Unterkante beschädigt werden kann bzw. die Hindernisse beschädigt oder abgetragen werden. Um dies zu vermeiden, ist es benannt, die Pflugschar gegenüber dem Traggestell höhenverstellbar auszubilden. Hierdurch kann die Pflugschar, sobald sie auf ein Hindernis auffährt, gegenüber dem Traggestell hochbewegt werden, wodurch das Hindernis von der Pflugschar überfahren wird.In the operation of snow plows, which are moved over floor surfaces, there is the difficulty that in the bottom surfaces obstacles, such as curbs, paving stones, manhole covers and the like., May be on which the ploughshare ascends, causing the ploughshare, especially in the lower edge can be damaged or the obstacles are damaged or removed. To avoid this, it is named to make the ploughshare height adjustable with respect to the support frame. As a result, the ploughshare, as soon as it encounters an obstacle, are moved up against the support frame, whereby the obstacle is run over by the ploughshare.

Eine andere Lösung dieses Problems besteht darin, die Pflugschar mit einer Scharplatte aus einem gummielastischen Material auszubilden. Dabei wird die Scharplatte beim Auffahren auf ein starres Hindernis elastisch verformt, wodurch sie über das Hindernis hinweggelangt. Derartige Scharplatten bestehen aus Gummiplatten mit einer Stärke von 30 mm bis 50 mm, welche aufgrund dieser Dicke in sich relativ steif bzw. starr sind.Another solution to this problem is to form the ploughshare with a share plate of a rubber-elastic material. In this case, the share plate is elastically deformed when driving on a rigid obstacle, whereby they pass over the obstacle. Such share plates are made of rubber plates with a thickness of 30 mm to 50 mm, which are relatively stiff or rigid due to this thickness.

Es sind weiters Pflugscharen bekannt, welche ein mehrteiliges Traggestell aufweisen, wobei die einzelnen Teile des Traggestells um angenähert vertikale Achsen verschwenkbar miteinander gelenkig verbunden sind und an den einzelnen Teilen des Scharträgers eine einstückige Scharplatte aus einem gummielastischen Material starr befestigt ist. Derartige Pflugscharen bestehen z.B. aus einem mittleren Teil des Traggestells und zwei seitlichen Enden des Traggestells, welche am mittleren Teil um angenähert vertikale Achsen verschwenkbar angelenkt sind, wobei die aus einem gummielastischen Material bestehende Scharplatte an sämtlichen Teilen des Traggestells starr befestigt ist. Ein Verschwenken der beiden Endteile der Scharplatte ist deshalb von Vorteil, da hierdurch die Arbeitsweise des Schneepflugs an die räumlichen Gegebenheiten bzw. Erfordernissen angepasst werden kann.
Aufgrund der hohen Steifigkeit der Scharplatte können jedoch dabei die beiden Endteile des Traggestells nur um sehr geringe Winkel gegenüber dem mittleren Teil des Traggestells verschwenkt werden.There are also known plowshares, which have a multi-part support frame, wherein the individual parts of the support frame are pivotally connected to each other about approximately vertical axes pivotable and rigidly attached to the individual parts of the coulter a one-piece share plate of a rubber-elastic material. Such plowshares consist for example of a central part of the support frame and two lateral ends of the support frame, which are pivotally hinged to the central part by approximately vertical axes, wherein the existing of a rubber elastic material share plate is rigidly attached to all parts of the support frame. A pivoting of the two end portions of the share plate is therefore advantageous, since this way the operation of the snowplow can be adapted to the spatial conditions or requirements.
Due to the high rigidity of the share plate, however, the two end portions of the support frame can be pivoted only by very small angles relative to the central part of the support frame.

Der gegenständlichen Erfindung liegt somit die Aufgabe zugrunde, einen Schneepflug der eingangs beschriebenen Art derart zu verbessern, dass dieser Nachteil vermieden wird. Dies wird erfindungsgemäß dadurch erzielt, dass Teile der Scharplatte bzw. die gesamte Scharplatte am Traggestell für die Scharplatte gegenüber diesem verstellbar befestigt sind bzw. ist.The subject invention thus has the object to improve a snow plow of the type described above such that this disadvantage is avoided. This is achieved according to the invention in that parts of the share plate or the entire share plate are adjustably mounted on the support frame for the share plate relative to this or is.

Vorzugsweise ist das Traggestell für die Scharplatte mit einem Hauptteil und an zumindest einem seiner beiden seitlichen Enden mit einem gegenüber dem Hauptteil um eine zumindest angenähert vertikale Achse verschwenkbaren Endteil ausgebildet, wobei die Scharplatte am Hauptteil starr befestigt ist, wogegen sie an dem mindestens einen Endteil des Traggestells für die Scharplatte gegenüber diesem verstellbar befestigt ist.
Dabei kann das Traggestell für die Scharplatte mit einem mittleren Hauptteil und mit zwei Endteilen ausgebildet sein, welche gegenüber dem mittleren Hauptteil verschwenkbar sind, wobei die Scharplatte an den beiden Endteilen des Traggestells für die Scharplatte verstellbar, insbesondere gegenüber diesem verschiebbar, befestigt ist. Dabei kann sich der Hauptteil des Traggestells für die Scharplatte über angenähert die halbe Länge des gesamten Traggestells für die Scharplatte erstrecken.Preferably, the support frame for the share plate is formed with a main part and at least one of its two lateral ends with an opposite to the main part about an at least approximately vertical axis pivotable end part, wherein the share plate is rigidly fixed to the main part, whereas it at the at least one end portion of Support frame for the share plate relative to this adjustable is attached.
In this case, the support frame may be formed for the share plate with a central body and two end portions, which are opposite to the middle Main part are pivotable, wherein the share plate at the two end portions of the support frame for the share plate adjustable, in particular against this slidably mounted. In this case, the main part of the support frame for the share plate can extend over approximately half the length of the entire support frame for the share plate.

Vorzugsweise ist das Traggestell für die Pflugschar mit mindestens einem Stellzylinder ausgebildet, durch welchen das Traggestell für die Scharplatte gegenüber dem Traggestell für die Pflugschar um eine angenähert vertikale Achse verschwenkbar ist, und ist das Traggestell für die Scharplatte zur Verschwenkung des mindestens einen Endteils des Traggestells für die Scharplatte mit mindestens einem weiteren Stellzylinder ausgebildet.Preferably, the support frame for the ploughshare is formed with at least one actuating cylinder, through which the support frame for the share plate relative to the support frame for the ploughshare is pivotable about an approximately vertical axis, and is the support frame for the share plate for pivoting the at least one end portion of the support frame for the share plate formed with at least one further actuating cylinder.

Gemäß einer weiteren erfindungsgemäßen Ausführungsform ist das Traggestell für die Scharplatte mit zwei Teilen ausgebildet, welche um eine zumindest angenähert vertikale Achse miteinander verschwenkbar gelenkig verbunden sind, wobei die Scharplatte an beiden Teilen des Traggestells für die Scharplatte gegenüber diesen verstellbar, insbesondere verschiebbar, befestigt ist. Vorzugsweise ist dabei das Traggestell für die Pflugschar mit zwei Stellzylindern ausgebildet, durch welche die beiden Teile des Traggestells für die Scharplatte gegenüber dem Traggestell für die Pflugschar verschwenkbar sind.According to a further embodiment of the invention, the support frame for the share plate is formed with two parts which are pivotally connected to each other pivotable about an at least approximately vertical axis, wherein the share plate is fixed to both parts of the support frame for the share plate relative to these adjustable, in particular displaceable. Preferably, the support frame for the ploughshare with two adjusting cylinders is formed, through which the two parts of the support frame for the flocking plate relative to the support frame for the plowshare are pivotable.

Am Traggestell 3 ist die sich über dessen gesamte Länge erstreckende einstückige Scharplatte 4 befestigt, welche aus einem gummielastischen Material besteht und eine Dicke von 30 mm bis 50 mm aufweist.The support frame 3 consists of a central frame member 31 and two side frame members 32 which are pivotally connected to the central part 31 of the support frame 3 by approximately vertical axes and pivotable by means of actuating cylinder 23 with respect to this. On the support frame 3 extending over its entire length extending one-piece share plate 4 is fixed, which consists of a rubber-elastic material and has a thickness of 30 mm to 50 mm.

Der Schneepflug 2 ist mittels des Tragfahrzeuges 1 in Richtung des Pfeiles A längs einer Bodenfläche, von welcher Schnee oder Eis entfernt werden soll, verfahrbar. Aufgrund der Einstückigkeit der Scharplatte 4 erfolgt eine vollständige Räumung der Bodenfläche über die gesamte Breite des Schneepflugs 2. Der Schneepflug 2 ist mittels des Stellzylinders 12 in eine Transportstellung anhebbar bzw. in eine Betriebsstellung absenkbar. Das Traggestell 3 für die Scharplatte 4 ist gegenüber dem an das Tragfahrzeug 1 angekuppelten Traggestell 21 für die Scharplatte 4 mittels der beiden Stellzylinder 22 um die vertikale Achse 20 verschwenkbar und somit gegenüber der Fahrtrichtung A des Schneepflugs 2 in beliebige Schwenklagen verstellbar. Die beiden Endteile 32 des Traggestells 3 sind mittels der Stellzylinder 23 gegenüber dem mittleren Gestellteil 31 so verschwenkbar, dass sie mit diesem in Fahrtrichtung A einen Winkel bis etwa 70° und entgegen der Fahrtrichtung A einen Winkel bis etwa 40° einnehmen können. Durch diese mehrfachen Schwenklagen des Schneepflugs 2 bzw. von dessen Teilen kann den Erfordernissen für den Räumbetrieb sehr gut entsprochen werden.
Da die einstückige Scharplatte 4 aus hartelastischem Material hergestellt ist, werden durch diese am Boden befindliche Hindernisse dadurch überfahren, dass die Scharplatte 4 elastisch verformt wird.The snow plow 2 is movable by means of the support vehicle 1 in the direction of the arrow A along a bottom surface from which snow or ice is to be removed. Due to the integral nature of the share plate 4 is a complete evacuation of the bottom surface over the entire width of the snow plow 2. The snow plow 2 is by means of the actuating cylinder 12 in a Transport position raised or lowered into an operating position. The support frame 3 for the share plate 4 is relative to the coupled to the support vehicle 1 support frame 21 for the share plate 4 by means of the two actuating cylinder 22 about the vertical axis 20 pivotally and thus adjustable with respect to the direction of travel A of the snowplow 2 in any pivoting positions. The two end portions 32 of the support frame 3 are so pivotable by means of the actuating cylinder 23 relative to the central frame member 31 that they can take an angle to about 70 ° and counter to the direction of travel A at an angle to about 40 ° with this in the direction of travel A. Through these multiple pivoting positions of the snow plow 2 or its parts, the requirements for the clearing operation can be met very well.
Since the one-piece share plate 4 is made of hard elastic material, these obstacles located at the bottom are run over by the fact that the share plate 4 is elastically deformed.

Die Scharplatte 4 ist am Traggestell 3 befestigt. Da jedoch die Scharplatte 4 eine sehr hohe Steifigkeit aufweist und gewährleistet werden muss, dass die beiden Endteile 42 derselben in einem großen Winkelbereich verschwenkbar sind, ist sie mit ihrem mittleren Teil 41 am mittleren Teil 31 des Traggestells 3 starr befestigt, wogegen sie an den seitlichen Teilen 32 des Traggestells 3 so befestigt ist, dass sie gegenüber diesen verstellbar ist. Hierdurch wird es ermöglicht, dass die beiden seitlichen Endteile 42 der Scharplatte 4 gegenüber dem mittleren Teil 41 der Scharplatte 4 um bis zu 110° in beliebige Schwenklagen verschwenkbar sind.The share plate 4 is attached to the support frame 3. However, since the share plate 4 has a very high rigidity and must be ensured that the two end portions 42 thereof are pivotable in a wide range of angles, it is rigidly fixed with its central part 41 on the central part 31 of the support frame 3, whereas it on the lateral Parts 32 of the support frame 3 is fixed so that it is adjustable with respect to these. This makes it possible that the two lateral end portions 42 of the share plate 4 with respect to the central part 41 of the share plate 4 by up to 110 ° in any pivotal positions are pivoted.

Nachstehend ist anhand der FIG.2 und FIG.2A die Befestigung der Scharplatte 4 am Traggestell 3 erläutert. Wie daraus ersichtlich ist, ist die Scharplatte 4 von einer Vielzahl von Befestigungsbolzen 51 und 52 durchsetzt, wobei die im mittleren Bereich 41 der Scharplatte 4 befindlichen Befestigungsbolzen 51 mit dem mittleren Teil 31 des Traggestells 3 starr verschraubt sind. Demgegenüber sind die seitlichen Teile 32 des Traggestells 3 mit Schlitzen 33 ausgebildet, in welchen die die seitlichen Teile 42 der Scharplatte 4 durchsetzenden Bolzen 52 verschiebbar geführt sind, wodurch die seitlichen Teile 42 der Scharplatte 4 gegenüber den seitlichen Teilen 32 des Traggestells 3 verschiebbar befestigt sind. Aufgrund dieser Beweglichkeit der seitlichen Teile 42 der Scharplatte 4 können diese gegenüber dem mittleren Teil 41 der Scharplatte 4 in Fahrtrichtung A Winkel bis etwa 70° und entgegen der Fahrtrichtung A Winkel bis etwa 40° einschließen. Im Bereich der Bolzenköpfe der Bolzen 51 und 52 kann die Scharplatte 4 durch Platten z.B. aus Metall verstärkt sein.The following is based on the FIG.2 and FIG.2A explains the attachment of the share plate 4 on the support frame 3. As can be seen, the share plate 4 is penetrated by a plurality of fastening bolts 51 and 52, wherein located in the central region 41 of the share plate 4 fastening bolts 51 are rigidly bolted to the central part 31 of the support frame 3. In contrast, the lateral parts 32 of the support frame 3 are formed with slots 33 in which the lateral parts 42 of the share plate 4 passing bolts 52 are slidably guided, whereby the lateral parts 42 of the share plate 4 relative to the lateral parts 32 of the support frame 3 are slidably mounted , Due to this mobility of the lateral parts 42 of the share plate 4, these can be compared to the central part 41 of the share plate 4 in the direction of travel A angle to about 70 ° and opposite the direction of travel A angle to include about 40 °. In the area of the bolt heads of the bolts 51 and 52, the share plate 4 can be reinforced by plates, for example made of metal.

In den FIG.3, FIG.3A und FIG.3B sind die seitlichen Teile 32 des Traggestells 3 für die Scharplatte 4 und damit die seitlichen Teile 42 der Scharplatte 4 entgegen der Fahrtrichtung A um etwa 30° nach hinten abgeschwenkt. Auch diese Verschwenkung ist im Hinblick auf die hohe Steifigkeit der Scharplatte 4 deshalb möglich, da die Befestigungsbolzen 52 in den Schlitzen 33 geführt sind, wodurch die seitlichen Teile 42 der Scharplatte 4 gegenüber den seitlichen Teilen 32 des Traggestells 3 für die Scharplatte 4 verschiebbar sind.In the FIG.3, FIG.3A and FIG.3B are the side portions 32 of the support frame 3 for the share plate 4 and thus the side portions 42 of the share plate 4 against the direction of travel A by about 30 ° swung backwards. This pivoting is therefore possible in view of the high rigidity of the share plate 4, since the fastening bolts 52 are guided in the slots 33, whereby the lateral parts 42 of the share plate 4 relative to the lateral parts 32 of the support frame 3 for the share plate 4 are displaceable.

In den FIG.4, FIG.4A und FIG.4B einer der beiden seitlichen Teile 42 der Scharplatte 4 entgegen der Fahrtrichtung A um etwa 30° verschwenkt, wogegen der andere seitliche Teile 42 der Scharplatte 4 in Fahrtrichtung A um etwa 70° verschwenkt ist. Trotz der hohen Steifigkeit der Scharplatte 4 ist diese starke Verschwenkung deshalb möglich, da die Befestigungsbolzen 52, mittels welcher der seitliche Teil 41 der Scharplatte 4 am seitlichen Teil 32 des Traggestells 3 befestigt ist, in den an diesem vorgesehenen Führungsschlitzen 33 geführt sind, wodurch der seitliche Teil 42 der Scharplatte 4 gegenüber dem seitlichen Teil 32 des Traggestells 3 für die Scharplatte 4 verschiebbar ist.In the FIG.4, FIG.4A and FIG.4B one of the two lateral parts 42 of the share plate 4 is pivoted counter to the direction of travel A by about 30 °, whereas the other lateral parts 42 of the share plate 4 is pivoted in the direction of travel A by about 70 °. Despite the high rigidity of the share plate 4, this strong pivoting is possible because the fastening bolts 52, by means of which the lateral part 41 of the share plate 4 is secured to the lateral part 32 of the support frame 3, are guided in the guide slots 33 provided on this, whereby the lateral part 42 of the share plate 4 relative to the lateral part 32 of the support frame 3 for the share plate 4 is displaceable.

Wie dies vorstehend anhand der Zeichnungen erläutert ist, ist der erfindungsgemäße Schneepflug in eine Vielzahl von Lagen einstellbar, wodurch den Erfordernissen des Räumbetriebes in optimaler Weise entsprochen wird:

  • Mittels der beiden Stellzylinder 22 ist die Pflugschar 2 in unterschiedliche Schräglagen gegenüber der Fahrtrichtung A verstellbar. Mittels der weiteren Stellzylinder 23 sind die seitlichen Teile 42 der Scharplatte 4 gegenüber dem mittleren Teil 41 der Scharplatte 4 unabhängig voneinander in Fahrtrichtung bis zu einem Winkel von etwa 70° und entgegen der Fahrtrichtung bis zu einem Winkel von etwa 40° verschwenkbar.
As explained above with reference to the drawings, the snow plow according to the invention is adjustable in a plurality of layers, whereby the requirements of the clearing operation are optimally met:
  • By means of the two actuating cylinders 22, the ploughshare 2 is adjustable in different inclinations relative to the direction of travel A. By means of the further actuating cylinder 23, the lateral parts 42 of the share plate 4 relative to the central part 41 of the share plate 4 are independently pivotable in the direction of travel to an angle of about 70 ° and counter to the direction of travel up to an angle of about 40 °.

In den FIG. 5, FIG.5A und FIG.5B ist eine zweite Ausführungsform eines erfindungsgemäßen Schneepflugs 2a dargestellt. Hierbei ist am Traggestell 21a für den Schneepflug 2a ein Traggestell 3a für eine Scharplatte 4a um eine angenähert vertikale Achse 20a verschwenkbar gelagert. Das Traggestell 3a besteht aus zwei miteinander gelenkig verbundenen Gestellteilen 32a, welche mittels Stellzylindern 22a um die vertikale Achse 20a gegeneinander in beliebige Lagen verschwenkbar sind. Die Scharteile 42a sind an den Teilen 32a des Traggestells 3a für die Scharplatte 4a mittels Befestigungsbolzen 52a befestigt. Weiters sind die Teile 32a des Traggestells 3a mit Führungsschlitzen 33a ausgebildet, in welchen Befestigungsbolzen 52a geführt sind. Obgleich die einstückige Scharplatte 4a, welche aus einem hartelastischen Material mit einer Dicke von 30 mm bis 50 mm besteht, eine sehr hohe Steifigkeit aufweist, sind deren beiden seitlichen Teile 42a deshalb in großen Winkeln gegeneinander verstellbar, da die Befestigungsbolzen 52a in den Führungsschlitzen 33a geführt sind, wodurch die beiden Scharteile 42a gegenüber den beiden Teilen 32a des Traggestells 3a verschiebbar sind.In the FIG. 5, FIG.5A and FIG.5B a second embodiment of a snow plow 2a according to the invention is shown. Here, on the support frame 21a for the snowplow 2a, a support frame 3a for a share plate 4a is pivotally mounted about an approximately vertical axis 20a. The support frame 3a consists of two hinged together frame parts 32a, which by means of adjusting cylinders 22a about the vertical axis 20a against each other in any positions are pivotable. The hinge parts 42a are fixed to the parts 32a of the support frame 3a for the share plate 4a by means of fixing bolts 52a. Furthermore, the parts 32a of the support frame 3a are formed with guide slots 33a in which fastening bolts 52a are guided. Although the one-piece share plate 4 a, which is made of a hard elastic material having a thickness of 30 mm to 50 mm, has a very high rigidity, the two lateral parts 42 a are therefore mutually adjustable at large angles, since the fastening bolts 52 a are guided in the guide slots 33 a are, whereby the two Scharteile 42a relative to the two parts 32a of the support frame 3a are displaceable.

Gemäß den Fig.5 FIG.5A und FIG.5B sind die beiden Scharteile 42a mittels der Stellzylinder 22a so verstellt, dass sie sich in einer Ebene befinden, welche mit der Fahrtrichtung A etwa einen rechten Winkel einschließt.
Gemäß den FIG.6, FIG.6A und FIG.6B sind die beiden Scharteile 42a mittels der beiden Stellzylinder 22a entgegen der Fahrtrichtung gegeneinander so verstellt, dass sie miteinander einen Winkel von etwa 130° einschließen. Gemäß den FIG.6 und FIG.7A sind die beiden Scharteile 42a mittels der beiden Stellzylinder 22a in Fahrtrichtung A so gegeneinander verstellt, dass sie miteinander einen Winkel von etwa 130° einschließen.
Da die Stellzylinder 22a unabhängig voneinander steuerbar sind, können die beiden Scharteile 42a gegenüber der Fahrtrichtung A in beliebige Lagen verschwenkt werden.According to the Fig.5 FIG.5A and FIG.5B the two Scharteile 42a are adjusted by means of the actuating cylinder 22a so that they are in a plane which includes with the direction of travel A about a right angle.
According to the FIG.6, FIG.6A and FIG.6B, the two Scharteile 42a by means of the two actuating cylinder 22a against the direction of travel against each other so adjusted that they enclose an angle of about 130 ° with each other. According to the FIG.6 and FIGURE 7A are the two Scharteile 42a adjusted by means of the two actuating cylinder 22a in the direction of travel A against each other so that they enclose an angle of about 130 ° with each other.
Since the actuating cylinders 22a are independently controllable, the two hinge parts 42a can be pivoted relative to the direction of travel A into any desired positions.

Diese zweite Ausführungsform ist gegenüber der ersten Ausführungsform insofern vereinfacht, dass für die Verschwenkung der beiden Scharteile 42a in beliebige Lagen gegenüber der Fahrtrichtung A und in beliebige Winkellagen zueinander nur zwei Stellzylinder 22a erforderlich sind.
Auch dabei ist eine einstückige Scharplatte 4a aus hartelastischem Material vorgesehen und muss eine hohe Anpassung der Scharplatte 4a an unterschiedliche Winkellagen der beiden Scharteile 42a zueinander gewährleistet sein. Diesem Erfordernis wird dadurch entsprochen, dass die beiden Scharteile 42a mittels der in Führungsschlitzen 33a geführten Befestigungsbolzen 52a an den beiden Teilen 32a des Traggestells 3a verschiebbar befestigt sind.This second embodiment is simplified compared to the first embodiment in that for the pivoting of the two Scharteile 42a in any position relative to the direction of travel A and in any angular positions to each other only two actuating cylinder 22a are required.
Here, too, a one-piece share plate 4a made of hard elastic material is provided and a high adaptation of the share plate 4a to different angular positions of the two share parts 42a to each other must be ensured. This requirement is met by the fact that the two hinge parts 42a are slidably mounted on the two parts 32a of the support frame 3a by means of the fastening bolts 52a guided in guide slots 33a.
