Description

Die Erfindung betrifft einen Adapter für ein Schnellwechselsystem, einen zu diesem Adapter passenden Schnellwechsler und ein Schnellwechselsystem mit einem solchen Adapter und Schnellwechsler.The invention relates to an adapter for a quick-change system, a quick-change device that fits this adapter, and a quick-change system with such an adapter and quick-change device.

Derartige Schnellwechselsysteme werden zum einfachen und bequemen Wechseln von unterschiedlichen Anbaugeräten an Baumaschinen eingesetzt. Damit können z.B. Schwenklöffel, Greifer, Scheren, Verdichter, Magnete, Hydraulikhammer oder andere Anbaugeräte in wenigen Sekunden und mit hohem Sicherheitsstandard von einer Fahrerkabine aus z.B. an einem Ausleger eines Baggers an- bzw. abgekuppelt werden. Sie enthalten in der Regel einen anbaugeräteseitigen Adapter und einen an der Baumaschine angeordneten Schnellwechsler, der an einer Seite z.B. klauenförmige erste Aufnahmen zur Halterung eines am Adapter angeordneten ersten Kopplungselements und an der anderen Seite zweite Aufnahmen mit mindestens einem zwischen einer Lösestellung und einer Verriegelungsstellung bewegbaren Verriegelungselement zur lösbaren Halterung eines am Adapter angeordneten zweiten Kopplungselements aufweist.Such quick-change systems are used for easy and convenient changing of different attachments on construction machines. This means that, for example, swivel buckets, grabs, shears, compactors, magnets, hydraulic hammers or other attachments can be coupled or uncoupled from a driver's cab, e.g. As a rule, they contain an adapter on the attachment side and a quick coupler arranged on the construction machine, which has e.g for releasably holding a second coupling element arranged on the adapter.

Aus der EP 1 599 637 A1 ist ein gattungsgemäßes Schnellwechselsystem bekannt. Dieses weist einen Adapter mit zwei zwischen parallelen Seitenwagen in einem vorgegebenen Abstand voneinander angeordneten Kopplungselementen zur Verbindung des Adapters mit einem Schnellwechsler auf. Der zum Adapter gehörende Schnellwechsler enthält an einer Seite klauenförmige erste Aufnahmen für das erste Kopplungselement und weist an der anderen Seite zweite Aufnahmen mit zwei zwischen einer Lösestellung und einer Verriegelungsstellung bewegbaren Verriegelungselementen zur lösbaren Halterung des zweiten Kopplungselements auf. Die beiden Kopplungselemente sind rohrförmig ausgebildet und weisen einen einheitlichen Durchmesser auf der gesamten Länge auf. An dem einen Kopplungselement ist ein Träger für Kupplungen und Sensoreinheiten befestigt und an dem anderen Kopplungselement sind Sensoren zur Erfassung der korrekten Kupplungsposition angeordnet.From the EP 1 599 637 A1 a generic quick-change system is known. This has an adapter with two coupling elements arranged at a predetermined distance from one another between parallel sidecars for connecting the adapter to a quick coupler. The quick coupler belonging to the adapter contains claw-shaped first receptacles for the first coupling element on one side and second receptacles on the other side with two locking elements that can be moved between a release position and a locking position for releasably holding the second coupling element. The two coupling elements are tubular and have a uniform diameter over the entire length. A carrier for couplings and sensor units is fastened to one coupling element and sensors for detecting the correct coupling position are arranged on the other coupling element.

Aufgabe der Erfindung ist es, einen Adapter, einen zugehörigen Schnellwechsler und ein Schnellwechselsystem mit einem derartigen Adapter und Schnellwechsler zu schaffen, die eine verbesserte Führung zwischen dem Adapter und dem Schnellwechsler ermöglichen.The object of the invention is to create an adapter, an associated quick coupler and a quick change system with such an adapter and quick coupler that enable improved guidance between the adapter and the quick coupler.

Diese Aufgabe wird durch einen Adapter mit den Merkmalen des Anspruchs 1, durch einen Schnellwechsler mit den Merkmalen des Anspruchs 8 und durch ein Schnellwechselsystem mit den Merkmalen des Anspruchs 12 gelöst. Zweckmäßige Ausgestaltungen und vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by an adapter having the features of claim 1, by a quick coupler having the features of claim 8 and by a quick-change system having the features of claim 12. Expedient configurations and advantageous developments of the invention are specified in the dependent claims.

Bei dem erfindungsgemäßen Adapter weist zumindest eines der beiden Kopplungselemente zwei voneinander beabstandete schlankere Kopplungsbereiche zum Eingriff mit dazugehörigen Aufnahmen des Schnellwechslers und einen dazwischen angeordneten Führungsbereich mit einem gegenüber den Kopplungsbereichen vergrößerten Querschnitt auf. Das Kopplungselement mit den beiden voneinander beanstandeten schlankeren Kopplungsbereichen und dem dazwischen angeordneten Führungsbereich ist als zylindrischer Bolzen mit einem geringeren Durchmesser in den Kopplungsbereichen und einem vergrößerten Durchmesser im Führungsbereich ausgeführt. Durch den im Durchmesser erweiterten Führungsbereich am Kopplungselement kann eine zusätzliche Führung des Adapters an dem Schnellwechsler erreicht werden Dies ermöglicht nicht nur eine Positionierhilfe beim Ankoppeln des Adapters an den Schnellwechsler, sondern gewährleistet auch eine verbesserte Führung im gekoppelten Zustand. Auf diese Weise können z.B. betriebsbedingte Schwingungen und dadurch verursachte Schwingungsbrüche oder andere Beschädigungen reduziert werden. Durch die positionsgenauere Führung und Halterung können außerdem Beschädigungen an den elektrischen oder hydraulischen Kupplungselementen vermieden werden. Darüber hinaus wir eine Verbesserung der Kraftübertragung erreicht.In the adapter according to the invention, at least one of the two coupling elements has two spaced, slimmer coupling areas for engagement with associated receptacles of the quick coupler and a guide area arranged between them with a cross section that is larger than the coupling areas. The coupling element with the two slimmer coupling areas spaced apart from one another and the guide area arranged between them is designed as a cylindrical bolt with a smaller diameter in the coupling areas and an enlarged diameter in the guide area. Additional guidance of the adapter on the quick coupler can be achieved by the guide area on the coupling element, which is enlarged in diameter. This not only enables a positioning aid when coupling the adapter to the quick coupler, but also ensures improved guidance in the coupled state. In this way, for example, operational vibrations and the resulting vibration fractures or other damage can be reduced. Thanks to the more precise positioning and mounting, damage to the electrical or hydraulic coupling elements can also be avoided. In addition, we achieved an improvement in power transmission.

In einer weiteren vorteilhaften Ausführung können an den Übergängen von den äußeren Kopplungsbereichen zu dem inneren Führungsbereich seitliche Führungsflächen vorgesehen sein.In a further advantageous embodiment, lateral guide surfaces can be provided at the transitions from the outer coupling areas to the inner guide area.

Das mit dem zusätzlichen Führungsbereich versehene Kopplungselement kann einteilig ausgebildet oder aus mehreren Teilen zusammengesetzt sein. So kann z.B. das Kopplungselement als einteilige Welle mit unterschiedlichen Durchmessern ausgeführt sein.The coupling element provided with the additional guide area can be designed in one piece or composed of several parts. For example, the coupling element can be designed as a one-piece shaft with different diameters.

Der im Querschnitt vergrößerte Führungsbereich kann aber auch dadurch hergestellt werden, dass auf eine Welle mit gleichmäßigem Durchmesser eine Hülse, ein Ringsegment oder eine ähnliche Erweiterung aufgesetzt und diese mit Welle verschweißt oder auf andere Weise fest mit der Welle verbunden werden.However, the guide area with an enlarged cross section can also be produced by placing a sleeve, a ring segment or a similar extension on a shaft with a uniform diameter and welding it to the shaft or firmly connecting it to the shaft in some other way.

Eine weitere Führung und Positionierung kann auch dadurch erreicht werden, dass an mindestens einem der Kopplungselemente zusätzliche Positionierelemente zum formschlüssigen Eingriff mit korrespondierenden Formschlusselementen am Schnellwechsler angeordnet sind. Dadurch kann auch verhindert werden, dass ein nicht an die Anschlüsse des Schnellwechslers angepasster und damit nicht den Sicherheitsbestimmungen genügender Adapter mit einem Schnellwechsler gekoppelt wird. Die Ankopplung mechanisch baugleicher aber hydraulisch unterschiedlicher Schnellwechsler und Adapter kann so vermieden und somit die Sicherheit erhöht werden.Further guidance and positioning can also be achieved in that additional positioning elements are arranged on at least one of the coupling elements for form-fitting engagement with corresponding form-fitting elements on the quick coupler. This can also prevent an adapter that is not adapted to the connections of the quick coupler and therefore does not meet the safety regulations from being coupled to a quick coupler. The coupling of mechanically identical but hydraulically different quick couplers and adapters can thus be avoided, thus increasing safety.

Die Positionierelemente an dem Kopplungselement können z.B. als Nuten zu Eingriff vorstehender Formschlusselemente am Schnellwechsler ausgebildet sein. Die Positionierelemente an dem Kopplungselement können aber auch als Vorsprünge zum Eingriff in entsprechende Vertiefungen am Schnellwechsler ausgeführt sein. Auch andere Positionier- oder Formschlusselemente zum gegenseitigen formschlüssigen Eingriff sind möglich. Die Positionierelemente sind zweckmäßigerweise an dem Führungsteil des Kopplungselements angeordnet. Sie können aber auch an den anderen Bereichen des Kopplungselements angeordnet sein.The positioning elements on the coupling element can be designed, for example, as grooves for engaging protruding form-fitting elements on the quick coupler. However, the positioning elements on the coupling element can also be designed as projections for engaging in corresponding depressions on the quick coupler. Other positioning or form-fitting elements for mutual form-fitting engagement are also possible. The positioning elements are expediently arranged on the guide part of the coupling element. However, they can also be arranged on the other areas of the coupling element.

Ein erfindungsgemäßer Schnellwechsler weist an einer Seite erste Aufnahmen zur Aufnahme eines ersten Kopplungselements und an der anderen Seite zweite Aufnahmen zur Aufnahme eines zweiten Kopplungselements auf, wobei zumindest zwischen den ersten Aufnahmen ein zurückversetzter oder ausgesparter Aufnahmebereich zur Aufnahme eines im Querschnitt erweiterten Führungsbereichs des ersten Kopplungselements vorgesehen ist. Auch zwischen den zweiten Aufnahmen kann ein entsprechender zurückversetzter oder ausgesparter Aufnahmebereich zur Aufnahme eines im Querschnitt erweiterten Führungsbereichs des zweiten Kopplungselements vorhanden sein.A quick coupler according to the invention has first receptacles on one side for accommodating a first coupling element and on the other side second receptacles for accommodating a second coupling element, wherein at least between the first receptacles there is a recessed or recessed receiving area for accommodating a guide area of the first coupling element that is enlarged in cross section is. A corresponding recessed or cut-out receiving area for receiving a guide area of the second coupling element that is enlarged in cross-section can also be present between the second receptacles.

Zweckmäßigerweise sind an dem zurückversetzten oder ausgesparten Aufnahmebereich seitliche Führungsflächen vorhanden. Auch in dem Aufnahmebereich können ferner zusätzliche Formschlusselemente zum formschlüssigen Eingriff mit korrespondierenden Positionierelementen am Schnellwechsler angeordnet sein. Die Formschlusselemente können an einer innerhalb des Aufnahmebereichs befestigten Leiste angeordnet oder auch direkt an dem Schnellwechsler angeformt sein.Lateral guide surfaces are expediently present on the set-back or recessed receiving area. Also in the recording area can also additional form-fitting elements can be arranged for form-fitting engagement with corresponding positioning elements on the quick coupler. The positive-locking elements can be arranged on a bar fastened within the receiving area or also be formed directly on the quick coupler.

In einer besonders vorteilhaften Ausführung kann ein definierter Anschluss des Schnellwechslers dadurch erreicht werden, dass die Formschlusselemente am Schnellwechsler und die korrespondieren Positionierelemente am Adapter eine definierte Form und/oder vorgegebene Abstände aufweisen. Die Formschlusselemente können z.B. als Vorsprünge oder Ansätze mit unterschiedlichen Abmessungen und/oder spezifischen Abständen ausgebildet sein. In einer für die Kopplung und Verbindung vorteilhaften Ausführung können die Formschlusselemente z.B. als Stege mit keil- oder trapezförmigen Querschnitt ausgebildet ausgeführt sein. Die Formschlusselemente können aber auch als Vertiefungen zum Eingriff entsprechender Vorsprünge an dem Kopplungselement ausgebildet sein. Auch andere, zueinander passende Formschluss- und Positionierelemente zur Bildung einer definierten Schnittstelle in Art einer codierten Verbindung sind möglich.In a particularly advantageous embodiment, a defined connection of the quick coupler can be achieved in that the positive locking elements on the quick coupler and the corresponding positioning elements on the adapter have a defined shape and/or predetermined distances. The form-fitting elements can be designed, for example, as projections or shoulders with different dimensions and/or specific distances. In an embodiment that is advantageous for the coupling and connection, the positive-locking elements can be designed, for example, as webs with a wedge-shaped or trapezoidal cross-section. However, the positive-locking elements can also be in the form of indentations for engaging corresponding projections on the coupling element. Other form-fitting and positioning elements that match one another are also possible to form a defined interface in the form of a coded connection.

Die Erfindung betrifft außerdem ein Schnellwechselsystem mit einem vorstehend beschriebenen Adapter und einem mit dem Adapter kuppelbaren Schnellwechsler zum einfachen Wechseln eines Anbaugeräts an Fahrzeugen.The invention also relates to a quick-change system with an adapter described above and a quick-change device that can be coupled to the adapter for easy changing of an attachment on vehicles.

In Figur 1 ist ein erstes Ausführungsbeispiel eines Schnellwechselsystems mit einem Adapter 1 und einem zugehörigen Schnellwechsler 2 zum einfachen Wechseln von Anbaugeräten an Fahrzeugen, insbesondere Baumaschinen, in einer gekuppelten Stellung gezeigt. Mit einem derartigen Schnellwechselsystem können z.B. Schwenklöffel, Greifer, Scheren, Magnete, Verdichter, Hydraulikhammer oder andere mechanische bzw. hydraulische Anbaugeräte einfach und bequem von einer Fahrerkabine aus an einem Ausleger oder einem anderen Anbauteil eines Baufahrzeugs an- bzw. abgekuppelt werden.In figure 1 a first exemplary embodiment of a quick-change system with an adapter 1 and an associated quick-change device 2 for easy changing of attachments on vehicles, in particular construction machinery, is shown in a coupled position. With such a quick-change system, for example, swivel buckets, grippers, shears, magnets, compactors, hydraulic hammers or other mechanical or hydraulic attachments can be easily and conveniently coupled to or decoupled from a driver's cab on a boom or other attachment of a construction vehicle.

Der in Figur 2 gesondert dargestellte, an einem Anbaugerät befestigbare Adapter 1 enthält eine Grundplatte 3 und zwei zueinander parallele, rechtwinklig zur Grundplatte 3 angeordnete und voneinander beabstandete Seitenwangen 4, zwischen denen ein erstes bolzenförmiges Kopplungselement 5 und ein davon in einem vorgegebenen Abstand beabstandetes zweites bolzenförmiges Kopplungselement 6 zur lösbaren Verbindung mit dem Schnellwechsler 2 angeordnet sind. Die beiden bolzenförmigen Kopplungselemente 5 und 6 sind mit ihren jeweiligen Enden in entsprechende Bohrungen 7 bzw. 8 in den beiden Seitenwangen 4 des Adapters 1 eingesteckt und dort fixiert.the inside figure 2 The separately shown adapter 1, which can be fastened to an attachment, contains a base plate 3 and two side walls 4 which are parallel to one another, are arranged at right angles to the base plate 3 and are spaced apart from one another, between which a first bolt-shaped coupling element 5 and a second bolt-shaped coupling element 6 spaced at a predetermined distance from it for detachable Connection to the quick coupler 2 are arranged. The two bolt-shaped coupling elements 5 and 6 are inserted with their respective ends into corresponding bores 7 and 8 in the two side panels 4 of the adapter 1 and fixed there.

Der in Figur 4 einzeln dargestellte Schnellwechsler 2 ist z.B. an einem Ausleger eines Baggers montierbar. Er enthält an einer Seite nach vorne offene, erste Aufnahmen 9 zur Aufnahme und Halterung des ersten bolzenförmigen Kopplungselements 5 und an der anderen Seite nach unten offene zweite Aufnahmen 10 zur Aufnahme des zweiten bolzenförmigen Kopplungselements 6. Die nach vorne offenen ersten Aufnahmen 9 sind klauen- oder gabelförmig ausgeführt. Die nach unten offenen Aufnahmen 10 weisen eine gekrümmte untere Anlagefläche 11 zur Anlage des zweiten bolzenförmigen Kopplungselements 6 auf. Der Schnellwechsler 2 enthält in Figur 4 erkennbare Führungsbohrungen 12, in denen zwei hier nicht erkennbare Verriegelungsbolzen verschiebbar geführt und hydraulisch zwischen einer eingezogenen Lösestellung und einer ausgefahrenen Verriegelungsstellung verfahrbar angeordnet sind. In der ausgefahrenen Verriegelungsstellung werden die nach unten offenen zweiten Aufnahmen 10 von den in den Führungsbohrungen 12 angeordneten Verriegelungsbolzen an der Unterseite geschlossen, so dass das zweite bolzenförmige Kopplungselement 6 von dem Verriegelungsbolzen untergriffen wird und der Adapter 1 am Schnellwechsler 2 gehalten werden kann.the inside figure 4 individually illustrated quick coupler 2 can be mounted, for example, on a boom of an excavator. It contains first receptacles 9, which are open towards the front on one side, for receiving and holding the first bolt-shaped coupling element 5, and on the other side, second receptacles 10, which are open downwards, for receiving the second bolt-shaped coupling element 6. The first receptacles 9 are open at the front claw- or fork-shaped. The downwardly open receptacles 10 have a curved lower contact surface 11 for contacting the second bolt-shaped coupling element 6 . The quick coupler 2 contains in figure 4 recognizable guide bores 12, in which two not visible here locking bolts are slidably guided and arranged hydraulically movable between a retracted release position and an extended locking position. In the extended locking position, the downwardly open second receptacles 10 are closed by the locking bolts arranged in the guide bores 12 on the underside, so that the second bolt-shaped coupling element 6 is gripped by the locking bolt and the adapter 1 can be held on the quick coupler 2.

In der gezeigten Ausführung enthält der Schnellwechsler 2 einen Träger 13, der an einer Seite zwei klauenförmige Aufnahmen 9 für das erste Kopplungselement 5 und auf der anderen Seite zwei Aufnahmen 10 für das zweite Kopplungselement 6 enthält. An zwei an der Oberseite des Trägers 13 angeordneten parallelen Seitenteilen 14 sind außerdem durchgängige Aufnahmeöffnungen 15 für nicht dargestellte Befestigungsbolzen zur Befestigung des Schnellwechslers 2 an einem Ausleger eines Baggers oder einem Anschlussteil eines anderen Baufahrzeugs vorgesehen.In the embodiment shown, the quick coupler 2 contains a carrier 13 which contains two claw-shaped receptacles 9 for the first coupling element 5 on one side and two receptacles 10 for the second coupling element 6 on the other side. In addition, continuous receiving openings 15 for fastening bolts, not shown, for fastening the quick coupler 2 to a boom of an excavator or a connection part of another construction vehicle are provided on two parallel side parts 14 arranged on the upper side of the carrier 13 .

Um den Adapter 1 an dem Schnellwechsler 2 anzukuppeln, wird der in der Regel an einem Ausleger eines Baggers angeordnete Schnellwechsler 2 zunächst so bewegt, dass das erste bolzenförmige Kopplungselement 5 am Adapter 1 in die klauenförmigen Aufnahmen 9 auf der einen Seite des Schnellwechslers 2 eingefahren wird. Dann wird der Schnellwechsler 2 mit noch zurückgezogenen Verriegelungsbolzen um das erste bolzenförmige Kopplungselement 5 so geschwenkt, dass das zweite bolzenförmige Kopplungselement 6 am Adapter 1 zur Anlage an den Anlageflächen 11 der nach unten offenen Aufnahmen 10 auf der anderen Seite des Schnellwechslers 2 gelangt. Anschließend können die in den Führungsbohrungen 12 im Träger 13 des Schnellwechslers 2 verschiebbar angeordneten Verriegelungsbolzen hydraulisch ausgefahren werden, so dass das zweite bolzenförmige Kopplungselement 6 am Adapter 1 von den beiden Verriegelungsbolzen an dem Schnellwechsler 2 untergriffen und der Adapter 1 somit an dem Schnellwechsler 2 gehalten wird.In order to couple the adapter 1 to the quick coupler 2, the quick coupler 2, which is usually arranged on a boom of an excavator, is first moved in such a way that the first bolt-shaped coupling element 5 on the adapter 1 is inserted into the claw-shaped receptacles 9 on one side of the quick coupler 2 . The quick coupler 2 is then pivoted around the first bolt-shaped coupling element 5 with the locking bolt still retracted in such a way that the second bolt-shaped coupling element 6 on the adapter 1 comes to rest on the contact surfaces 11 of the receptacles 10, which are open at the bottom, on the other side of the quick coupler 2. The locking bolts, which are movably arranged in the guide bores 12 in the carrier 13 of the quick coupler 2, can then be extended hydraulically, so that the second bolt-shaped coupling element 6 on the adapter 1 is gripped under by the two locking bolts on the quick coupler 2 and the adapter 1 is thus held on the quick coupler 2 .

Wie aus den Figuren 2 und 3 hervorgeht, weist das zu den klauenförmigen Aufnahmen 9 des Schnellwechslers 2 gehörende erste Kopplungselement 5 zwei voneinander beabstandete schlankere Kopplungsbereiche 16 zum Eingriff mit den klauenförmigen Aufnahmen 9 des Schnellwechslers 2 und einen dazwischen angeordneten Führungsbereich 17 mit einem gegenüber den Kopplungsbereichen 16 vergrößerten Querschnitt auf. In der gezeigten Ausführung ist das erste Kopplungselement 5 als Bolzen mit unterschiedlichen Durchmessern ausgeführt. In den Kopplungsbereichen 16 weist das bolzenförmige erste Kopplungselement 5 einen geringeren Durchmesser und im Führungsbereich einen gegenüber den Kopplungsbereichen 16 vergrößerten Durchmesser auf. In Figur 3 ist erkennbar, dass an den Übergängen von den äußeren Kopplungsbereichen 16 zu dem inneren Führungsbereich 17 seitliche Führungsflächen 18 vorgesehen sind. Durch den im Querschnitt erweiterten Führungsbereich 17 kann eine zusätzliche Führung des Adapters 1 an dem Schnellwechsler 2 erreicht werden Dadurch kann nicht nur eine Positionierhilfe beim Ankoppeln des Adapters an den Schnellwechsler, sondern auch eine verbesserte Führung im gekoppelten Zustand erreicht werden. Außerdem können z.B. betriebsbedingte Schwingungen und dadurch verursachte Schwingungsbrüche oder andere Beschädigungen reduziert werden. Durch die positionsgenauere Führung und Halterung können ferner Beschädigungen an den elektrischen oder hydraulischen Kupplungselementen vermieden werden. Darüber hinaus wir eine Verbesserung der Kraftübertragung erreicht.How from the Figures 2 and 3 shows that the first coupling element 5 belonging to the claw-shaped receptacles 9 of the quick coupler 2 has two spaced, slimmer coupling areas 16 for engagement with the claw-shaped receptacles 9 of the quick coupler 2 and a guide area 17 arranged between them with a cross section that is larger than the coupling areas 16. In the embodiment shown, the first coupling element 5 is designed as a bolt with different diameters. The bolt-shaped first coupling element 5 has a smaller diameter in the coupling regions 16 and a larger diameter in the guide region than in the coupling regions 16 . In figure 3 it can be seen that lateral guide surfaces 18 are provided at the transitions from the outer coupling areas 16 to the inner guide area 17 . Additional guidance of the adapter 1 on the quick coupler 2 can be achieved by the guide area 17 with an enlarged cross section. This not only provides a positioning aid when coupling the adapter to the quick coupler, but also improved guidance in the coupled state. In addition, for example, operational vibrations and vibration fractures caused by them or other damage can be reduced. In addition, damage to the electric or hydraulic coupling elements can be avoided due to the more precise positioning of the guide and holder. In addition, we achieved an improvement in power transmission.

In Figur 2 ist erkennbar, dass an dem zu den zweiten Aufnahmen 10 des Schnellwechslers 2 gehörenden zweiten bolzenförmigen Kopplungselement 6 des Adapters 1 ein Kupplungselementträger 19 zur Halterung von adapterseitigen Kupplungselementen für eine Kupplung mit schnellwechslerseitigen Kupplungselementen 2 befestigt ist. Über am Kupplungselementträger 19 angeordnete - hier nicht dargestellte - adapterseitige Kupplungselemente können zur Energieversorgung eines Anbaugeräts am Adapter 1 vorgesehene Energieanschlüsse beim Ankoppeln des Adapters 1 an den Schnellwechsler 2 automatisch mit entsprechenden Energieversorgungsleitungen am Schnellwechsler 2 verbunden werden. Dadurch kann ein Anbaugerät z.B. mit Hydraulikfluid, elektrischer Energie oder einem anderen Energieträger versorgt werden. Bei der gezeigten Ausführung ist der Kupplungselementträger 19 über Haltestege 20 an dem zweiten bolzenförmigen Kopplungselement 6 befestigt.In figure 2 It can be seen that a coupling element carrier 19 for holding coupling elements on the adapter side for a coupling with coupling elements 2 on the quick coupler side is attached to the second bolt-shaped coupling element 6 of the adapter 1 belonging to the second receptacles 10 of the quick coupler 2 . About on the coupling element carrier 19 arranged - not shown here - adapter-side coupling elements can be automatically connected to corresponding energy supply lines on the quick coupler 2 to supply energy to an attachment on the adapter 1 when coupling the adapter 1 to the quick coupler 2 . As a result, an attachment can be supplied with hydraulic fluid, electrical energy or another energy source, for example. In the embodiment shown, the coupling element carrier 19 is fastened to the second bolt-shaped coupling element 6 via holding webs 20 .

Auch das zweite Kopplungselement 6 kann zwei voneinander beabstandete schlankere Kopplungsbereiche 21 zum Eingriff mit den zugehörigen Aufnahmen 10 des Schnellwechslers 2 und einen dazwischen angeordneten Führungsbereich 22 mit einem gegenüber den Kopplungsbereichen 16 vergrößerten Querschnitt aufweisen. Das zweite Kopplungselement 6 kann aber auch auf der gesamten Länge einen gleichmäßigen Durchmesser haben.The second coupling element 6 can also have two spaced, slimmer coupling areas 21 for engagement with the associated receptacles 10 of the quick coupler 2 and a guide area 22 arranged between them with an enlarged cross section compared to the coupling areas 16 . However, the second coupling element 6 can also have a uniform diameter over the entire length.

In Figur 4 ist der zu dem Adapter 1 gehörende Schnellwechsler 2 gezeigt. Dieser weist zwischen den beiden klauenförmigen Aufnahmen 9 einen zurückversetzten oder ausgesparten Aufnahmebereich 23 zur Aufnahme des Führungsbereichs 17 am ersten Kopplungselement 5 des Adapters 1 auf. Der in Figur 5 vergrößert dargestellte Aufnahmebereich 23 ist an die Außenkontur des Führungsbereichs 17 angepasst. Er weist eine etwas größere Breite als der Führungsbereich 17 des ersten Kopplungselements 5 auf. Auch die Tiefe des Aufnahmebereichs 23 ist an den vergrößerten Querschnitt des Führungsbereichs 17 angepasst. Ferner können auch an dem Führungsbereich 17 seitliche Führungsflächen 24 vorgesehen sein.In figure 4 the quick coupler 2 belonging to the adapter 1 is shown. Between the two claw-shaped receptacles 9 , this has a recessed or recessed receiving area 23 for receiving the guide area 17 on the first coupling element 5 of the adapter 1 . the inside figure 5 The receiving area 23 shown enlarged is adapted to the outer contour of the guide area 17 . It has a slightly larger width than the guide area 17 of the first coupling element 5 . The depth of the receiving area 23 is also adapted to the enlarged cross section of the guide area 17 . Furthermore, lateral guide surfaces 24 can also be provided on the guide area 17 .

In den Figuren 6 bis 10 ist ein weiteres Ausführungsbeispiel eines Schnellwechselsystems mit einem Adapter 1 und einem zugehörigen Schnellwechsler 2 zum einfachen Wechseln von Anbaugeräten an Fahrzeugen, insbesondere Baumaschinen, in einer gekuppelten Stellung gezeigt. Diese Ausführung unterscheidet sich von dem vorstehend beschriebenen Ausführungsbeispiel lediglich dadurch, dass an dem Kopplungselement 5 des Adapters 1 zusätzliche Positionierelemente 25 zum formschlüssigen Eingriff mit korrespondierenden Formschlusselementen 26 am Schnellwechsler 2 angeordnet sind. Dadurch kann eine weitere Führung und Positionierung erreicht werden. Außerdem kann auf diese Weise auch verhindert werden, dass ein nicht an die Anschlüsse des Schnellwechslers angepasster und damit nicht den Sicherheitsbestimmungen genügender Adapter mit einem Schnellwechsler gekoppelt wird. Die Ankopplung mechanisch baugleicher aber hydraulisch unterschiedlicher Schnellwechsler und Adapter kann so vermieden und somit die Sicherheit erhöht werden. Ansonsten entspricht der Aufbau des in Figur 7 gezeigten Adapters 1 und des in Figur 9 dargestellten Schnellwechslers 2 der vorherigen Ausführung, so dass einander entsprechende Bauteile mit denselben Bezugszeichen versehen sind. Bezüglich deren Aufbau und Funktion wird auf das erste Ausführungsbeispiel Bezug genommen.In the Figures 6 to 10 Another exemplary embodiment of a quick-change system with an adapter 1 and an associated quick-change device 2 for easy changing of attachments on vehicles, in particular construction machinery, is shown in a coupled position. This embodiment differs from the exemplary embodiment described above only in that additional positioning elements 25 are arranged on the coupling element 5 of the adapter 1 for form-fitting engagement with corresponding form-fitting elements 26 on the quick coupler 2 . As a result, further guidance and positioning can be achieved. In addition, it can also be prevented in this way that an adapter that is not adapted to the connections of the quick coupler and therefore does not meet the safety regulations is coupled to a quick coupler. The coupling of mechanically identical but hydraulically different quick couplers and adapters can thus be avoided, thus increasing safety. Otherwise the structure of the in figure 7 shown adapter 1 and in figure 9 illustrated quick coupler 2 of the previous embodiment, so that corresponding components are provided with the same reference numerals. With regard to their structure and function, reference is made to the first exemplary embodiment.

Bei der in Figur 7 gezeigten Ausführung sind die Positionierelemente 25 an dem ersten Kopplungselement 5 des Adapters 1 als ringförmige Nuten ausgeführt. Die dazugehörigen Formschlusselemente 26 am Schnellwechsler 2 sind gemäß Figur 9 als Stege mit einem trapez- oder keilförmigen Querschnitt ausgebildet. Wie aus Figur 10 hervorgeht, sind die Formschlusselemente 26 bei der gezeigten Ausführung an einer innerhalb des Aufnahmebereichs 23 befestigten Leiste 27 angeordnet. Die Formschlusselemente 26 können aber auch an dem Schnellwechsler 2 angeformt sein. Die Positionierelemente 25 und die daugehörigen Formschlusselemente 26 sind sowohl von der Form als auch von der Anordnung aufeinander abgestimmt.At the in figure 7 In the embodiment shown, the positioning elements 25 on the first coupling element 5 of the adapter 1 are designed as annular grooves. The associated positive-locking elements 26 on the quick coupler 2 are in accordance with figure 9 designed as webs with a trapezoidal or wedge-shaped cross section. How out figure 10 As can be seen, the form-fitting elements 26 in the embodiment shown are arranged on a strip 27 fastened within the receiving area 23 . However, the form-fitting elements 26 can also be formed on the quick coupler 2 . The positioning elements 25 and the associated positive-locking elements 26 are matched to one another both in terms of shape and arrangement.
