Description

Die Erfindung bezieht sich auf eine Bohlenanordnung für einen Straßenfertiger gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a screed assembly for a paver according to the preamble of claim 1.

Straßenfertiger zum Einbau von Beton oder bituminösem Einbaumischgut verfügen üblicherweise über eine Bohlenanordnung, die hinter dem Straßenfertiger her geschleppt wird. Mit dieser Bohlenanordnung wird das verteilte Einbaumischgut geglättet und bereits erheblich vorverdichtet, bevor anschließend die endgültige Verdichtung beispielsweise mit einer Walze erfolgt.Road pavers for the installation of concrete or bituminous Einbbaumischgut usually have a screed assembly, which is towed behind the paver ago. With this screed arrangement, the distributed Einbaumischgut is smoothed and already significantly pre-compacted before then the final compaction takes place for example with a roller.

Besonders günstig ist es, wenn die Bohle in einer Richtung quer zur Einbau-Fahrtrichtung des Straßenfertigers eine variable Länge hat, um unterschiedliche Einbaubreiten erzielen zu können. Zu diesem Zweck sind drei unterschiedliche Typen von Bohlenanordnungen entwickelt worden, die jeweils unterschiedliche Vor- und Nachteile haben.It is particularly favorable if the screed has a variable length in a direction transverse to the direction of installation of the road paver in order to be able to achieve different installation widths. For this purpose, three different types of screed arrangements have been developed, each having different advantages and disadvantages.

In einem ersten Typ sind vor und/oder hinter einer Grundbohle eine rechte und eine linke Ausziehbohle vorgesehen, die in Einbau-Fahrtrichtung versetzt zu einander angeordnet sind. Der Vorteil dieser Anordnung besteht darin, dass zwischen den beiden Ausziehbohlen kein Einbaumaterial eingeklemmt wird, wenn die beiden Ausziehbohlen aufeinander zu bewegt werden. Nachteilig ist jedoch, dass die beiden Ausziehbohlen nicht symmetrisch zueinander angeordnet sind, sodass die volle Einbaubreite an unterschiedlichen Punkten entlang der Einbau-Fahrtrichtung erreicht wird.In a first type, a right and a left extension screed are provided before and / or behind a base screed, which are arranged offset in the installation direction of travel to each other. The advantage of this arrangement is that no paving material is clamped between the two Ausziehbohlen when the two Ausziehbohlen are moved towards each other. The disadvantage, however, is that the two extending screeds are not arranged symmetrically to one another, so that the full pave width is achieved at different points along the installation direction of travel.

Bei einem weiteren Typ einer Auszieh-Bohlenanordnung sind eine rechte und eine linke Ausziehbohle jeweils unmittelbar hinter einer Grundbohle angeordnet.In another type of pull-out screed assembly, right and left screed planks are each disposed immediately behind a base screed.

Für bestimmte Baustellenverhältnisse kann es vorteilhaft sein, wenn die Ausziehbohlen nicht hinter, sondern vor der Grundbohle angeordnet sind, da sich auf diese Weise Hindernisse wie Gullies leichter umgehen lassen. Für diesen Zweck wird ein dritter Typ einer Bohlenanordnung verwendet, bei dem zwei Ausziehbohlen unmittelbar vor der Grundbohle angeordnet sind. Dieser Typ einer Bohlenanordnung wird im Englischen auch als "Front-Mounted-Screed" bezeichnet. Die Erfindung bezieht sich auf diesen dritten Typ von Bohlenanordnungen.For certain construction site conditions, it may be advantageous if the extendable planks are not arranged behind, but in front of the base board, since in this way obstacles such as gullies can be avoided more easily. For this purpose, a third type of screed assembly is used, in which two extension boards are located immediately in front of the base board. This type of screed assembly is also referred to in English as "front-mounted screed". The invention relates to this third type of screed arrangements.

Nachteilig an den Bohlenanordnungen vom Typ "Front-Mounted-Screed" ist, dass sich das noch nicht verarbeitete Einbaumaterial zwischen den beiden Ausziehbohlen befindet, wenn diese aufeinander zu bewegt werden. Dies kann dazu führen, dass das Einbaumaterial zwischen den beiden Ausziehbohlen eingeklemmt wird, wenn ein bestimmter Abstand zwischen den beiden Ausziehbohlen unterschritten wird. Die Ausziehbohlen können dann nicht weiter aufeinander zu bewegt werden.A disadvantage of the screed arrangements of the type "front-mounted screed" is that the not yet processed paving material between the two Ausziehbohlen is when they are moved towards each other. This can cause the paving material between the two Ausziehbohlen is trapped when a certain distance between the two Ausziehbohlen is exceeded. The Ausziehbohlen can then not be moved closer to each other.

Um dieses Problem zu umgehen, sind Pflugstrukturen oder Abweiseglieder entwickelt worden, die an den Innenflächen der beiden Ausziehbohlen angeordnet sind. Solche Pflugstrukturen oder Abweiseglieder gehen beispielsweise aus der US 4,379,653 , aus der US 6,106,192 A , die eine Bohlenanordnung mit den Merkmalen des Oberbegriffs des Anspruchs 1 offenbart, oder aus der nachveröffentlichten europäischen Patentanmeldung EP 09002132.0 hervor. Diese Abweisevorrichtungen oder Pflugstrukturen verlagern das Einbaumischgut zur Mittelachse der Bohlenanordnung oder unter die Grundbohle, wenn sich die beiden Ausziehbohlen aufeinander zu bewegen, um ein Einklemmen von Einbaumischgut zwischen den Ausziehbohlen zu verhindern. Nachteilig ist jedoch, dass die Ausziehbohlen nicht mehr über ihre volle Länge relativ zur Grundbohle ausgezogen werden können, da die Pflugstruktur nicht zum Einbauen zur Verfügung steht. Folglich verringert sich die Ausziehlänge der Ausziehbohlen um die Ausdehnung der Pflugstruktur quer zur Einbau-Fahrtrichtung.To circumvent this problem, plow structures or deflectors have been developed which are arranged on the inner surfaces of the two Ausziehbohlen. Such plow structures or Abweiseglieder go for example from the US 4,379,653 , from the US 6,106,192 A , which discloses a screed assembly having the features of the preamble of claim 1, or from the post-published European patent application EP 09002132.0 out. These deflectors or plow structures displace the potting material to the centerline of the screed assembly or under the base screed as the two extend screeds move toward each other to prevent trapping of built-in debris between the screeds. The disadvantage, however, is that the extendible planks can no longer be pulled out over their full length relative to the base board, since the plow structure is not available for installation. Consequently, the Ausziehlänge the Ausziehbohlen reduced by the extension of the plow structure transverse to the installation direction of travel.

Aufgabe der vorliegenden Erfindung ist es, eine Bohlenanordnung mit konstruktiv möglichst einfachen Mitteln dahingehend zu verbessern, dass trotz effektiver Abweisung von Einbaumischgut beim Einziehen der Ausziehbohlen nahezu die gesamte Länge der Ausziehbohlen zum Ausziehen gegenüber der Grundbohle zur Verfügung steht.Object of the present invention is to improve a screed assembly with structurally simple means to the effect that, despite effective rejection of Einbaumischgut when pulling the Ausziehbohlen almost the entire length of the Ausziehbohlen is available to take off against the base board.

Diese Aufgabe wird gelöst durch eine Bohlenanordnung mit den Merkmalen des Anspruchs 1. Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by a screed assembly having the features of claim 1. Advantageous developments of the invention are specified in the subclaims.

Bei der erfindungsgemäßen Bohlenanordnung ist an der Grundbohle und/oder an wenigstens an einer der Ausziehbohlen ein relativ zur Grundbohle beziehungsweise zur Ausziehbohle verstellbares Abweiseglied angebracht. Die Verstellbarkeit des Abweiseglieds widerspricht dem üblichen Vorurteil, dass das Abweiseglied nur dann die erforderlichen, hohen Kräfte auf das schwere Einbaumischgut ausüben kann, wenn es starr an der Grundbohle oder an der Ausziehbohle befestigt ist. Der Vorteil der erfindungsgemäßen Verstellbarkeit des Abweiseglieds liegt darin, dass der Platzbedarf für das Abweiseglied in der eingezogenen Stellung der Ausziehbohlen sehr klein gehalten werden kann, sodass tatsächlich nahezu die gesamte Länge der Ausziehbohlen zum Ausziehen zur Verfügung steht. Die Verstellbarkeit erlaubt es auch, das Abweiseglied lediglich beim Einziehen der Ausziehbohlen oder sogar nur während einer beschränkten Zeitspanne während des Einziehens in eine Stellung zu bringen, in der das Abweiseglied tatsächlich Einbaumischgut verlagert. Zu den übrigen Zeitpunkten behindert das Abweiseglied den Einbauvorgang nicht.In the screed arrangement according to the invention, a deflecting member which is adjustable relative to the base pile or to the drawing sheet is attached to the base pile and / or to at least one of the drawing sheets. The adjustability of the Abweiseglieds contradicts the usual prejudice that the Abweiseglied can exert the necessary high forces on the heavy Einbaumischgut only if it is rigidly attached to the base board or on the Ausziehbohle. The advantage of the adjustability of the Abweiseglieds invention is that the space required for the Abweiseglied in the retracted position of the Ausziehbohlen can be kept very small, so that in fact almost the entire length of the Ausziehbohlen is available for undressing available. The adjustability also allows the deflector member to be brought into a position only during retraction of the extendible planks, or even only during a limited period of time during retraction, in which the deflector member actually displaces built-in debris. At the other times the deflector does not interfere with the installation process.

Vorzugsweise ist das Abweiseglied an der der anderen Ausziehbohle zugewandten Seite einer Ausziehbohle angeordnet. An diese Stelle ist der Einsatz des Abweiseglieds besonders effektiv, da andernfalls genau hier das Einklemmen von Einbaumischgut droht.Preferably, the deflecting member is disposed on the side of a Ausziehbohle facing the other Ausziehbohle. At this point, the use of Abweiseglieds is particularly effective because otherwise threatens exactly the trapping of Einbaumischgut.

Es würde genügen, wenn lediglich an einer der beiden Ausziehbohlen ein Abweiseglied vorgesehen ist. Besser ist es jedoch, wenn an jeder der Ausziehbohlen ein Abweiseglied vorgesehen ist, da auf diese Weise das Abweisen des Einbaumischguts gleichmäßig erfolgt und das einzelne Abweiseglied geringere Kräfte tragen muss.It would be sufficient if only one of the two Ausziehbohlen a Abweiseglied is provided. It is better, however, if a Abweiseglied is provided on each of the Ausziehbohlen, since in this way the rejection of Einbbaumischguts takes place evenly and the individual Abweiseglied must carry lower forces.

Vorteilhaft ist es, wenn das Abweiseglied mittels eines Antriebs verstellbar ist, insbesondere mittels eines Hydraulikantriebs. Ein Hydraulikantrieb hat dabei den Vorteil, dass er die erforderlichen Kräfte aufbringen kann, um das Abweiseglied entgegen der Trägheit des schweren Einbaumischguts halten und verstellen zu können.It is advantageous if the deflecting member is adjustable by means of a drive, in particular by means of a hydraulic drive. A hydraulic drive has the advantage that it can muster the necessary forces to hold the deflector against the inertia of heavy Einbaumischguts and adjust.

Vorzugsweise ist das Abweiseglied verstellbar zwischen einer an der Ausziehbohle oder einer Grundbohle anliegenden, inaktiven Stellung und einer von der jeweiligen Bohle beabstanden, aktiven Stellung. In der inaktiven Stellung behindert das Abweiseglied den Einbauvorgang nicht, und die jeweilige Bohle wird vergleichsweise kompakt. Zudem erleichtert das Beabstanden des Abweiseglieds von der Bohle in der aktiven Stellung das Abweisen von Einbaumischgut von der jeweiligen Bohle.Preferably, the deflector is adjustable between an inactive position adjacent to the extension screed or a base screed and an active position spaced from the respective screed. In the inactive position, the deflector does not interfere with the installation process and the particular screed becomes comparatively compact. In addition, the spacing of the deflector member from the screed in the active position facilitates the rejection of built-in mix from the respective screed.

Denkbar wäre es, dass das Abweiseglied verstellbar ist zwischen einer inaktiven Stellung, in der es sich parallel zur Einbau-Fahrtrichtung erstreckt, und einer aktiven Stellung, in der es sich unter einem Winkel zur Einbau-Fahrtrichtung erstreckt. In der inaktiven Stellung beeinflusst das Abweiseglied somit den Einbauprozess nicht. In der aktiven Stellung sorgt die Anstellung des Abweiseglieds unter einem Winkel zur Einbau-Fahrtrichtung dafür, dass sich das Einbaumischgut zur Mittelachse der Bohlenanordnung verlagert, wenn sich die Bohlenanordnung in der Einbau-Fahrtrichtung bewegt.It would be conceivable that the deflecting member is adjustable between an inactive position in which it extends parallel to the installation direction of travel, and an active position in which it extends at an angle to the installation direction of travel. In the inactive position, the deflector thus does not affect the installation process. In the active position, the employment of the Abweiseglieds at an angle to the installation direction of travel ensures that the Einbaumischgut shifts to the central axis of the screed assembly when the screed assembly moves in the installed direction of travel.

Besonders effektiv wird das Abweisen des Einbaumischguts, d.h. in diesem Fall das Verlagern des Einbaumischguts in Richtung auf die Mittelachse der Bohlenanordnung, wenn das Abweiseglied in der aktiven Stellung unter einem Winkel von 30° bis 55° relativ zur Einbau-Fahrtrichtung angestellt ist.Especially effective is the rejection of the built-in batch, i. in this case, displacing the built-in cargo toward the central axis of the screed assembly when the deflector is set in the active position at an angle of 30 ° to 55 ° relative to the installed direction of travel.

Vorzugsweise ist das Abweiseglied stufenlos zwischen der inaktiven und der aktiven Stellung verstellbar, um sich besonders gut an den sich ändernden Abstand zwischen den beiden Ausziehbohlen beim Einziehen der Ausziehbohlen anpassen zu können.Preferably, the deflector is infinitely adjustable between the inactive and the active position, in order to be able to adapt particularly well to the changing distance between the two Ausziehbohlen when pulling the Ausziehbohlen can.

Denkbar ist es beispielsweise, dass das Abweiseglied schwenkbar an der Grundbohle und/oder an wenigstens einer der Ausziehbohlen angebracht ist. Dies hat den Vorteil, dass das Abweiseglied beispielsweise über ein Scharnier sicher an der jeweiligen Bohle befestigt ist, um auf diese Weise trotz einer Verstellbarkeit hohe Kräfte beim Abweisen des Einbaumischguts aufnehmen zu können.It is conceivable, for example, that the deflecting member is pivotally mounted on the base board and / or on at least one of the Ausziehbohlen. This has the advantage that the deflector is securely fastened to the respective screed, for example by means of a hinge in this way, despite an adjustability to be able to absorb high forces when rejecting the built-in goods.

In einer alternativen Ausführungsform umfasst das Abweiseglied eine oder besser zwei auf der in Einbau-Fahrtrichtung vorderen Seite der Grundbohle angeordnete Abweiseplatten. Bei dieser Ausführungsvariante können herkömmliche Ausziehbohlen verwendet werden, während lediglich die Grundbohle abgewandelt wird.In an alternative embodiment, the deflector member comprises one or better two deflector plates arranged on the front side of the base plank in the installation direction of travel. In this embodiment, conventional Ausziehbohlen can be used, while only the base board is modified.

Besonders zweckmäßig ist es bei dieser Ausführungsvariante, wenn die rückwärtigen inneren Ecken der Ausziehbohlen abgeschrägt oder abgerundet sind, um eine Bewegung der Abweiseplatten zuzulassen. Damit wird verhindert, dass die von der Grundbohle nach vorne gestellten Abweiseplatten das Einziehen der Ausziehbohlen behindern.It is particularly useful in this embodiment, when the rear inner corners of the Ausziehbohlen bevelled or rounded to allow movement of the Abweisplatten. This prevents the deflector plates provided by the base board from obstructing the pull-out boards.

Erfindungsgemäß ist die Verstell-Bewegung des Abweiseglieds an die Bewegung der Ausziehbohlen gekoppelt. Diese Kopplung könnte dafür sorgen, dass die Ausziehbohlen nahezu während der gesamten Einziehbewegung der Ausziehbohlen in ihre aktive Stellung gebracht werden. Noch günstiger wäre es jedoch, wenn die Verstell-Bewegung des Abweiseglieds proportional an die Bewegung der Ausziehbohlen gekoppelt wird.According to the invention, the adjustment movement of the deflector is coupled to the movement of the Ausziehbohlen. This coupling could ensure that the extendible planks are brought into their active position almost during the entire pulling movement of the Ausziehbohlen. It would be even better, however, if the displacement movement of the deflector is coupled proportionally to the movement of the Ausziehbohlen.

Eine automatische Kopplung der Verstell-Bewegung des Abweiseglieds an die Bewegung der Ausziehbohlen könnte erfolgen, indem zu diesem Zweck eine Kulisse und/oder eine elektrische oder elektronische Steuerung vorgesehen ist, oder aber eine mechanische Vorspannung der Abweiseglieds auf die aktive Stellung.An automatic coupling of the adjustment movement of the Abweiseglieds to the movement of the Ausziehbohlen could be done by a backdrop and / or electrical or electronic control is provided for this purpose, or a mechanical bias of the Abweiseglieds to the active position.

Schließlich bezieht sich die Erfindung auch auf einen Straßenfertiger mit einer Bohlenanordnung der vorstehend beschriebenen Art.Finally, the invention also relates to a paver with a screed assembly of the type described above.

Gleiche Komponenten sind in den Figuren durchgängig mit gleichen Bezugszeichen versehen.The same components are provided throughout the figures with the same reference numerals.

Figur 1 zeigt schematisch einen Straßenfertiger 1 mit einer erfindungsgemäßen Bohlenanordnung 2. Die Bohlenanordnung 2 wird im Einbau-Fahrtrichtung E hinter der Zugmaschine des Straßenfertigers 1 geschleppt. Zwischen der Zugmaschine des Straßenfertigers 1 und der Bohlenanordnung 2 befindet sich eine Querverteileinrichtung 3, beispielsweise zwei Querverteilerschnecken, um das zu verarbeitende Einbaumischgut über die Einbaubreite zu verteilen. FIG. 1 shows schematically a paver 1 with a screed assembly 2 according to the invention. The screed assembly 2 is towed in the installation direction of travel E behind the tractor of the paver 1. Between the tractor of the paver 1 and the screed assembly 2 is a transverse distribution device 3, for example, two Quererverteilerschnecken to distribute the to be processed Einbaumischgut on the pave width.

Die Bohlenanordnung 2 ist vom Typ "Front-Mounted-Screed", bei der eine rechte Ausziehbohle 4 und eine linke Ausziehbohle 5 vor einer gemeinsamen Grundbohle 6 angeordnet sind. Die Grundbohle 6 kann dabei einstückig sein oder aus mehreren Teilen bestehen. Jede der einzelnen Bohlen 4, 5, 6 verfügt über Mittel zum Glätten und verdichten von Einbaumischgut, beispielsweise in Form von Glättblechen oder Stampfern ("Tamper").The screed assembly 2 is of the "front-mounted screed" type in which a right screed 4 and a left screed 5 are disposed in front of a common base screed 6. The base pile 6 may be integral or consist of several parts. Each of the individual planks 4, 5, 6 has means for smoothing and compacting built-in material, for example in the form of screed plates or tampers ("tamper").

Bei der erfindungsgemäßen Bohlenanordnung 2 sind die beiden Ausziehbohlen 4, 5 jeweils unmittelbar zur Vorderseite 7 der Grundbohle 6 benachbart. In Richtung der Einbau-Fahrtrichtung E sind die beiden Ausziehbohlen 4, 5 folglich nicht zueinander versetzt.In the plank assembly 2 according to the invention, the two Ausziehbohlen 4, 5 are each adjacent directly to the front side 7 of the base pile 6. In the direction of installation direction of travel E, the two Ausziehbohlen 4, 5 are therefore not offset from each other.

In der in Figur 1 gezeigten, eingezogenen Stellung der Ausziehbohlen 4, 5 liegen diese mit ihren einander zugewandten Innenseiten 8 an einer (virtuellen) Mittelachse M der Bohlenanordnung 2 aneinander (wobei auch ein minimaler Spalt zwischen den beiden Ausziehbohlen 4, 5 verbleiben kann). In Richtung quer zur Einbau-Fahrtrichtung E entspricht die Länge einer Ausziehbohle 4, 5 etwa der halben Länge der Grundbohle 6.In the in FIG. 1 shown, retracted position of the Ausziehbohlen 4, 5 lie with their facing inner sides 8 at a (virtual) center axis M of the screed assembly 2 to each other (although a minimal gap between the two Ausziehbohlen 4, 5 may remain). In the direction transverse to the installation direction of travel E corresponds to the length of a Ausziehbohle 4, 5 about half the length of the base pile. 6

An der Innenseite 8 jeder Ausziehbohle 4, 5, d. h. an der der jeweils anderen Ausziehbohle 5, 4 zugewandten Seite 8, ist an jeder Ausziehbohle 4, 5 ein Abweiseglied 9 angebracht, das relativ zur jeweiligen Ausziehbohle 4, 5 verstellbar ist. Wie insbesondere aus Figur 3 hervorgeht, ist das Abweiseglied 9 jeweils eine senkrecht ausgerichtete Abweiseplatte, die um ein Scharnier 10 an der vorderen Innenkante der Ausziehbohle 4, 5 verschwenkbar ist.On the inner side 8 of each Ausziehbohle 4, 5, ie on the respective other Ausziehbohle 5, 4 facing side 8, a Abweiseglied 9 is attached to each Ausziehbohle 4, 5, which is relative to the respective Ausziehbohle 4, 5 adjustable. As in particular from FIG. 3 As can be seen, the deflector 9 is in each case a vertically oriented deflector plate, which is pivotable about a hinge 10 at the front inner edge of the Ausziehbohle 4, 5.

In der in Figur 1 gezeigten, eingezogenen Stellung der Ausziehbohlen 4, 5 liegen die Abweiseplatten 9 parallel zueinander in Einbau-Fahrtrichtung E aneinander an. Zum Verstellen der Abweiseplatten, d.h. zum Verschwenken der Abweiseplatten 9 um das jeweilige Scharnier 10, ist an jeder Ausziehbohle 4, 5 ein Hydraulikantrieb 11 vorgesehen.In the in FIG. 1 shown, retracted position of the Ausziehbohlen 4, 5 are the reject plates 9 parallel to each other in installation direction of travel E to each other. To adjust the reject plates, ie for pivoting the deflector plates 9 to the respective hinge 10, a hydraulic drive 11 is provided on each Ausziehbohle 4, 5.

Figur 2 zeigt die Bohlenanordnung 2 in der ausgezogenen Stellung der Ausziehbohlen 4, 5. Um in diese Stellung zu gelangen, sind die Ausziehbohlen 4, 5 in Ausziehrichtung A, d.h. quer zur Einbau-Fahrtrichtung E, gegenüber der Grundbohle 6 verfahren worden. Um diese Bewegung der Ausziehbohlen 4, 5 zu bewirken, sind geeignete Antriebe, beispielsweise Hydraulikantriebe, und Führungsmittel (beispielsweise Führungsschienen oder Führungsstangen) vorgesehen. FIG. 2 shows the screed assembly 2 in the extended position of the Ausziehbohlen 4, 5. In order to get into this position, the Ausziehbohlen 4, 5 in the withdrawal direction A, ie transverse to the installation direction of travel E, relative to the base pile 6 have been moved. In order to effect this movement of the Ausziehbohlen 4, 5, suitable drives, such as hydraulic drives, and guide means (for example, guide rails or guide rods) are provided.

Figur 2 zeigt, dass die Abweiseglieder 9, d.h. die Abweiseplatten, in ihrer Stellung parallel zur Einbau-Fahrtrichtung E verbleiben. Auf diese Weise beanspruchen sie quer zur Einbau-Fahrtrichtung E keinen oder nur minimalen Platz. Folglich steht die gesamte Länge der Ausziehbohlen 4, 5 zum Ausziehen zur Verfügung, und die Breite der Bohlenanordnung 2 quer zur Einbau-Fahrtrichtung E hat sich ausgehend von der in Figur 1 gezeigten Stellung (nahezu) verdoppelt. FIG. 2 shows that the Abweiseglieder 9, ie the reject plates remain in position parallel to the installation direction of travel E. In this way, they occupy transversely to the installation direction E no or only minimal space. Consequently, the entire length of the Ausziehbohlen 4, 5 is available for undressing, and the width of the screed assembly 2 transverse to the installation direction of travel E has, starting from the in FIG. 1 shown (almost) doubled position.

Figur 3 zeigt die Bohlenanordnung 2 beim anschließenden Einziehen der Ausziehbohlen 4, 5, d.h. bei einer Bewegung der Ausziehbohlen 4, 5 in einer Richtung A' entgegen der Ausziehrichtung A. Manuell oder automatisch, beispielsweise durch eine elektronische Steuerung, sind die Hydraulikantriebe 11 aktiviert worden, um die Abweiseglieder 9 von der in den Figuren 1 und 2 gezeigten, inaktiven Stellung in eine aktive Stellung zu versetzen. In dieser aktiven Stellung sind die Abweiseglieder 9 um die Scharniere 10 verschwenkt worden, sodass sie sich nun nicht mehr parallel zur Mittelachse M, sondern unter einem Winkel von etwa 40° zur Mittelachse erstrecken. Dieser Winkel kann zwischen 30° und 55° betragen. Wird die Bohlenanordnung 2 nun im Einbau-Fahrtrichtung E bewegt, weisen die Abweiseglieder 9 das zwischen ihnen befindliche Einbaumischgut in Richtung auf die Mittelachse M ab, sodass sich dieses Einbaumischgut nicht zwischen den beiden aufeinander zu bewegten Ausziehbohlen 4, 5 verklemmen kann. FIG. 3 shows the screed assembly 2 during subsequent retraction of the Ausziehbohlen 4, 5, ie, during a movement of the Ausziehbohlen 4, 5 in a direction A 'against the withdrawal direction A. Manually or automatically, for example by an electronic control, the hydraulic drives 11 have been activated to the deflectors 9 of the in the Figures 1 and 2 shown inactive position in an active position. In this active position the Abweiseglieder 9 have been pivoted about the hinges 10 so that they no longer extend parallel to the central axis M, but at an angle of about 40 ° to the central axis. This angle can be between 30 ° and 55 °. If the screed assembly 2 is now moved in the installation direction of travel E, the Abweiseglieder 9, the Einbaubischgut located between them in the direction of the central axis M, so that this Einbaumischgut can not jam between the two mutually moving Ausziehbohlen 4, 5.

Die Abweiseglieder 9 können ihre in Figur 3 gezeigte, aktive Stellung beibehalten, bis die Ausziehbohlen 4, 5 soweit aufeinander zu bewegt wurden, dass sich die Abweiseglieder 9 kontaktieren. Von diesem Zeitpunkt an werden die Abweiseglieder 9 durch die Hydraulikantriebe 11 allmählich zurück in ihre inaktive Stellung verschwenkt, während sich die Ausziehbohlen 4, 5 weiter aufeinander zu bewegen. So verkleinern die Abweiseglieder 9 kontinuierlich den inzwischen ihnen vorhandenen Spalt, sodass sich schließlich beim Erreichen der eingezogenen Stellung gemäß Figur 1 kein Einbaumischgut mehr zwischen den Abweisegliedern 9 befindet.The deflectors 9 can their in FIG. 3 maintained shown active position until the Ausziehbohlen 4, 5 were moved toward each other so far that contact the Abweiseglieder 9. From this point on, the deflector members 9 are gradually pivoted by the hydraulic drives 11 back into their inactive position, while the Ausziehbohlen 4, 5 continue to move towards each other. Thus, the deflector members 9 continuously reduce the gap which they now have, so that finally when reaching the retracted position according to FIG FIG. 1 no Einbaumischgut more between the Abweiseglieder 9 is located.

Die Abweiseglieder 9 können sich über die gesamte Höhe der Ausziehbohlen 4, 5 erstrecken oder lediglich über einen unteren Bereich der Ausziehbohlen 4, 5. Bei den Abweisegliedern 9 kann sich um die Wand der Ausziehbohlen 4, 5 handeln, oder um ein zusätzliches Blech vor der Innenwand.The Abweiseglieder 9 may extend over the entire height of the Ausziehbohlen 4, 5 or only over a lower portion of the Ausziehbohlen 4, 5. The Abweisegliedern 9 may be the wall of the Ausziehbohlen 4, 5, or an additional sheet before the interior wall.

Figur 4 zeigt ein zweites Ausführungsbeispiel einer erfindungsgemäßen Bohlenanordnung 2. Bei diesem Ausführungsbeispiel sind im Unterschied zum ersten Ausführungsbeispiel die als Bleche oder Abweiseplatten ausgebildeten Abweiseglieder 9 nicht an den Ausziehbohlen 4, 5, sondern an der Vorderseite 7 der Grundbohle 6 angeordnet. Die beiden Abweiseglieder 9 sind jeweils über ein Scharnier 10 an der Grundbohle 6 befestigt, wobei das Scharnier 10 wiederrum eine senkrechte Schwenkachse für die Abweiseglieder 9 definiert. FIG. 4 shows a second embodiment of a screed assembly according to the invention 2. In this embodiment, in contrast to the first embodiment designed as sheets or Abweiseglieder 9 are not arranged on the Ausziehbohlen 4, 5, but on the front side 7 of the base pile 6. The two Abweiseglieder 9 are each attached via a hinge 10 to the base pile 6, wherein the hinge 10 in turn defines a vertical pivot axis for the Abweiseglieder 9.

In der in der Figur 4 gezeigten, inaktiven Stellung liegen die beiden Abweiseglieder 9 parallel zur Vorderseite 7 der Grundbohle 6 an. Jedes der beiden Abweiseglieder 9 ist etwas länger als der Abstand zwischen der Mittelachse M und dem jeweiligen Scharnier 10. Folglich überlappen sich die Abweiseglieder 9 vor der Grundbohle 6. Jedes der Abweiseglieder 9 kann über einen Hydraulikantrieb 11 verstellbar sein, der in Figur 4 der Übersichtlichkeit halber nicht dargestellt ist.In the in the FIG. 4 shown inactive position, the two Abweiseglieder 9 parallel to the front side 7 of the base pile 6 at. Each of the two Abweiseglieder 9 is slightly longer than the distance between the central axis M and the respective hinge 10. Consequently, the Abweiseglieder 9 overlap in front of the base pile 6. Each of the Abweiseglieder 9 can be adjusted by a hydraulic drive 11, the FIG. 4 for the sake of clarity is not shown.

Die rückwärtigen inneren Ecken 12 der beiden Ausziehbohlen 4 sind konvex abgerundet. Alternativ könnten die Ecken 12 auch abgeschrägt sein. Die Abrundung oder Abschrägung an den Ecken 12 sorgt dafür, dass die Bewegung de Ausziehbohlen 4, 5 durch die Abweiseglieder 9 nicht behindert wird.The rear inner corners 12 of the two Ausziehbohlen 4 are convex rounded. Alternatively, the corners 12 could also be chamfered. The rounding or beveling at the corners 12 ensures that the movement de Ausziehbohlen 4, 5 is not hindered by the Abweiseglieder 9.

Figur 5 zeigt die Bohlenanordnung 2 bei der Bewegung der Ausziehbohlen 4, 5 in Einziehrichtung A', d.h. aufeinander zu. Die Abweiseglieder 9 sind von der inaktiven Stellung in ihre aktive Stellung gebracht worden, indem sie um die Scharniere 10 nach vorne verschwenkt wurden. In der aktiven Stellung liegen die beiden äußeren Kanten der Abweiseglieder 9 etwa auf der Mittelachse M. Auf diese Weise bilden die beiden Abweiseglieder 9 gemeinsam eine Pflugstruktur vor der Grundbohle 6. FIG. 5 shows the screed assembly 2 during the movement of the Ausziehbohlen 4, 5 in the drawing A ', ie towards each other. The deflectors 9 have been brought from the inactive position to their active position by being pivoted forward about the hinges 10. In the active position, the two outer edges of the Abweiseglieder 9 are approximately on the central axis M. In this way, the two Abweiseglieder 9 together form a plow structure in front of the base pile. 6

Wenn die Ausziehbohlen 4, 5 noch weiter aufeinander zu bewegt werden, wie in Figur 6 gezeigt, werden die Abweiseglieder 9 nach und nach eingeklappt, um die Bewegung der Ausziehbohlen 4, 5 nicht zu behindern. Dabei können die Abweiseglieder 9 an den abgerundeten oder abgeschrägten inneren Ecken 12 der Ausziehbohlen 4, 5 entlang gleiten. Denkbar wäre es insbesondere, dass die Abweiseglieder 9 dabei zwangsweise von den Ausziehbohlen 4, 5 von der aktiven in die inaktive Stellung zurück verstellt werden. Das eine Abweisglied 9 klappt vor dem anderen Abweiseglied ein, damit die beiden Abweiseglieder in der inaktiven Stellung wieder einander überlappen.When the extending screeds 4, 5 are moved even further towards each other, as in FIG FIG. 6 shown, the deflectors 9 are gradually folded so as not to hinder the movement of the Ausziehbohlen 4, 5. In this case, the Abweiseglieder 9 at the rounded or bevelled inner corners 12 of the Ausziehbohlen 4, 5 slide along. It would be conceivable, in particular, for the deflector members 9 to be forcibly moved back from the extendible planks 4, 5 from the active to the inactive position. The one deflector 9 works in front of the another deflector, so that the two Abweiseglieder overlap again in the inactive position.

Die durch die beiden Abweiseglieder 9 gebildete Pflugstruktur sorgt dafür, das zwischen den beiden Ausziehbohlen 4, 5 befindliche Einbaumischgut von der Mittelachse M nach außen zu transportieren, wenn sich die Bohlenanordnung 2 im Einbau-Fahrtrichtung E bewegt.The plow structure formed by the two Abweiseglieder 9 ensures that the built-in material between the two Ausziehbohlen 4, 5 transported from the central axis M to the outside when the plank assembly 2 moves in the installation direction of travel E.

Denkbar wäre es, in allen Ausführungsbeispielen der erfindungsgemäßen Bohlenanordnung 2 durch geeignete Sensoren die Position der Ausziehbohlen 4, 5 relativ zur Grundbohle 6 und die Einfahrgeschwindigkeit der Ausziehbohlen 4, 5 zu erfassen, um anhand der dadurch gewonnenen Messdaten die Bewegung des Abweiseglieds 9 zu steuern. Beispielsweise könnte das Abweiseglied 9 durch eine solche Steuerung erst dann von der inaktiven in die aktive Stellung gebracht werden, wenn die Ausziehbohlen 4, 5 einen Mindestabstand voneinander unterschreiten. Sobald ein zweiter, vorgegebener Abstand unterschritten wird, können die Abweiseglieder 9 allmählich von der aktiven in die inaktive Stellung zurück versetzt werden. Anstelle einer Steuerung der Verstellbewegung des Abweiseglieds 9 über die Wegmessung und die Einfahrgeschwindigkeit der Ausziehbohlen 4, 5 kann diese Steuerung auch allein über eine Wegmessung oder allein in Abhängigkeit von der Einfahrgeschwindigkeit der Ausziehbohlen 4, 5 erfolgen. Alternativ wäre es denkbar, das Verstellen des Abweiseglieds 9 manuell durch den Bediener des Straßenfertigers 1 vorzunehmen, oder die Bewegung mechanisch zu steuern, beispielsweise mittels einer entsprechenden Kulissenführung.It would be conceivable in all embodiments of the screed assembly 2 according to the invention by suitable sensors to detect the position of the Ausziehbohlen 4, 5 relative to the base pile 6 and the retraction speed of the Ausziehbohlen 4, 5 in order to control the movement of the Abweiseglieds 9 based on the measurement data obtained thereby. For example, the deflector 9 could be brought by such a control of the inactive to the active position only when the Ausziehbohlen 4, 5 below a minimum distance from each other. As soon as a second, predetermined distance is reached, the deflector members 9 can be gradually returned from the active to the inactive position. Instead of controlling the adjustment of the Abweiseglieds 9 on the distance measurement and the retraction speed of the Ausziehbohlen 4, 5, this control can also be done alone via a displacement measurement or alone depending on the retraction speed of the Ausziehbohlen 4, 5. Alternatively, it would be conceivable to make the adjustment of the deflector 9 manually by the operator of the paver 1, or to control the movement mechanically, for example by means of a corresponding slotted guide.

Eine weitere Variante der Erfindung besteht darin, den Antrieb 11 für das Abweiseglied 9 durch eine nach außen gerichtete Vorspannung zu ersetzten, beispielsweise ausgeübt durch eine Feder oder eine andere Spanneinheit, die das Abweiseglied 9 von der inaktiven in die aktive Stellung beaufschlagt. Sobald und solange die Stellung der Ausziehbohlen 4, 5 dies zulässt, sorgt in diesem Fall die Vorspannung dafür, dass sich das Abweiseglied 9 in der aktiven Stellung befindet, um Einbaumischgut seitlich zu verlagern.Another variant of the invention is to replace the drive 11 for the deflector 9 by an outward bias, for example, exerted by a spring or other clamping unit, which acts on the deflector 9 from the inactive to the active position. As soon as and as long as the position of the Ausziehbohlen 4, 5 permits, in this case, the bias ensures that the deflector 9 is in the active position to displace Einbaumischgut sideways.

Allgemein bezieht sich die Erfindung auf eine Bohlenanordnung 2 für einen Straßenfertiger 1, mit einer Grundbohle 6 und zwei in Einbau-Fahrtrichtung E vor der Grundbohle 6 angeordneten und quer zur Einbau-Fahrtrichtung E relativ zur Grundbohle 6 bewegbaren Ausziehbohlen 4, 5, dadurch gekennzeichnet, dass an der Grundbohle 6 und/oder an wenigstens einer der Ausziehbohlen 4, 5 ein relativ dazu verstellbares Abweiseglied 9 angebracht ist.In general, the invention relates to a screed assembly 2 for a paver 1, comprising a base screed 6 and two in the installation direction of travel E in front of the base screed 6 and transversely to the installation direction of travel E relative to the base screed 6 movable extendable screeds 4, 5, characterized that on the base pile 6 and / or on at least one of the Ausziehbohlen 4, 5, a relatively adjustable Abweiseglied 9 is attached.
