For better absorption of the forces acting on the box girder (23) and thus the mounting frame (34), the box girder is provided lying loosely on the mounting frame and all forces are combined so that they act on the box girder, so that the mounting frame and thus the chassis of Forces of the collecting container are free.

Description

Die vorliegende Erfindung bezieht sich auf einen Drehtrommel-Sammelbehälter zur Aufnahme und Beförderung von Müll oder sonstigem Schüttgut, bei dem der hintere Abschlußdeckel mit einem in den Sammelbehälter ragenden schraubenförmigen Leitblech versehen ist, das in Verbindung mit an der Drehtrommel-Innenwand angeordneten und mit dieser umlaufenden Mitnehmern (als Ausräumschnecke) das Gut in den Sammelbehälter abdrängt und (als Preßschnecke) in den Sammelbehälter hineindrückt und bei dem der Behälter sich in einem Kastenträger dreht, der sich auf einem mit einem Fahrgestell verbundenen Montagerahmen.abstützt.The present invention relates to a rotating drum collecting container for receiving and transporting garbage or other bulk material, in which the rear end cover is provided with a helical baffle protruding into the collecting container, which is arranged in connection with and rotating with the rotating drum inner wall Drivers (as a screw-out screw) pushes the goods into the collection container and (as a screw press) pushes the collection container in and in which the container rotates in a box girder, which rotates on a mounting frame connected to a chassis . supports.

Ein derartiger Drehtrommel-Sammelbehälter ist aus der DT-PS 1 144 185 bekannt und hinsichtlich seiner wesentlichen Elemente in Fig. 1 dargestellt. Er besteht aus einer Drehtrommel 1, deren hinteres Ende durch einen Ab-' schlußdeckel 2 abgeschlossen ist. Dieser Deckel, der bezogen auf das Fahrgestell 3 eines den Drehtrommel-Sammelbehälter transportierenden Fahrzeugs 4 hochklappbar ist, trägt einen in das Drehtrommelinnere ragenden abgestumpften Hohlkegel 5, an dessen Mantelaußenseite ein schraubenförmiges Leitblech 6 befestigt ist, das sich vom oberen Scheitelpunkt S am Abschlußdeckel bis über etwa 180 Grad zu einem Punkt E an der inneren Kegelstumpfebene erstreckt und somit eine Steigung aufweist, die sich auf dem genannten Winkelbereich über die ganze Tiefe des Kegelstumpfes 5 erstreckt. Das genannte Leitblech 6 ist in radialer Richtung um weitere 90° verlängert, jedoch nur in Form eines Kreissegmentes ohne Steigung. Dieses Kreissegment dient dazu, das durch die Schneckenförderwirkung des Leitbleches 6 im Zusammenwirken mit am Abschlußdeckel 2 und am Drehtrommelinnenraum axial verlaufenden Mitnehmerrippen aus einem Einschüttraum herausgeförderte und über Förderschnecken 7. in den Drehtrommelinnenraum abgedrängte Schüttgut am Zurückfallen in diesen Einschüttraum zu hindern.Such a rotary drum collecting container is known from DT-PS 1 144 185 and is shown in FIG. 1 with regard to its essential elements. It consists of a rotary drum 1 whose rear end is end cover 2 closed by a waste '. This cover, which can be folded up relative to the chassis 3 of a vehicle 4 transporting the rotary drum collecting container, carries a truncated hollow cone 5 projecting into the inside of the rotary drum, on the outside of which a screw-shaped guide plate 6 is fastened, which extends from the upper apex S on the cover plate to extends approximately 180 degrees to a point E on the inner truncated cone plane and thus has an incline which extends over the entire depth of the truncated cone 5 in the said angular range. Said baffle 6 is extended by a further 90 ° in the radial direction, but only in the form of a circular segment without a slope. This circular segment serves to convey the axially extending entraining ribs out of a pouring chamber by means of the screw conveying action of the guide plate 6 in cooperation with driving ribs on the end cover 2 and on the interior of the rotating drum and via conveyor screws 7. to prevent bulk material that has been pushed into the interior of the rotating drum from falling back into this storage space.

Die genannte Wirkung des in der Verlängerung des Leitblechs angebrachten Kreissegments hat auch im Hinblick auf die Verdichtung des Schüttgutes im Drehtrommelinnenraum Bedeutung. Nachdem das Schüttgut einerseits am Zurückfallen in die Einschüttöffnung gehindert wird, andererseits über die - diesbezüglich als Ausräumschnecke wirkenden - Leitbleche stets neues Schüttgut nachgeführt wird, dient das Kreisringsegment als Preßschnecke zum Verdichten des Schüttgutes im Drehtrommelinnenraum.The mentioned effect of the circular segment attached in the extension of the guide plate is also important with regard to the compression of the bulk material in the interior of the rotating drum. After the bulk material is prevented from falling back into the pouring opening on the one hand, and on the other hand new bulk material is fed through the baffles - which act as a removal screw in this regard - the circular ring segment serves as a compression screw for compacting the bulk material in the interior of the rotating drum.

Bei den bekannten Drehtrommel-Sammelbehältern zur Aufnahme und Beförderung von Müll oder sonstigem Schüttgut wird der Behälter 1 über einen am Umfang aufgeschweißten Zahnkranz 8 und einen vom Fahrzeugantrieb abgeleiteten - strichpunktiert gezeichneten - Nebenantrieb 9 in Drehbewegung versetzt und gehalten. Die Antriebsaggregate selbst sind dabei in einem sogenannten Montage- (oder Hilfs-) rahmen 10 gelagert, der den eigentlichen Nutzaufbau, also den Behälter 1 trägt, und der zu Reparatur- und Wartungszwecken vom eigentlichen Fahrgestell 3 des Fahrzeugs abgehoben werden kann. Auf der Grundlage dieses Montagerahmenkonzepts kann somit ein und dasselbe Fahrgestell mit unterschiedlichen Nützaufbauten bestückt werden.In the known rotary drum collecting containers for receiving and transporting garbage or other bulk material, the container 1 is set in rotary motion and held by means of a toothed ring 8 welded onto the circumference and a secondary drive 9 derived from the vehicle drive (shown in broken lines). The drive units themselves are mounted in a so-called assembly (or auxiliary) frame 10 which carries the actual useful structure, that is to say the container 1, and which can be lifted off the actual chassis 3 of the vehicle for repair and maintenance purposes. On the basis of this mounting frame concept, one and the same chassis can be equipped with different useful structures.

Bei den bekannten Drehtrommel-Müllfahrzeugen sind also - wie oben erwohnt - einerseits die Antriebsaggregate für den Drehbehälter.im Montagerahmen gelagert, andererseits jedoch stützt sich dieser Drehbehälter auf einem Großkugellager (siehe Position 11 in Fig. 1) ab, das seinerseits auf einem Lagerbock (siehe Position 12 in Fig. 1) aufliegt, der mit dem Fahrgestell fest verbunden ist. Somit treten also bei der Drehbewegung des Behälters Kräfte auf, die sowohl auf den Montagerahemen als auch auf das Fahrgestell einwirken, und zwar derart, daß resultierende Kraftkomponenten entstehen, die zu Schäden am Fahrgestell und/oder am Montagerahmen führen können.In the known rotary drum refuse collection vehicles, the drive units for the rotary container are stored in the mounting frame on the one hand, as is mentioned above, on the other hand, however, this rotary container is supported on a large ball bearing (see position 11 in FIG. 1), which in turn is supported on a bearing block ( see position 12 in Fig. 1), which is firmly connected to the chassis. Thus, during the rotational movement of the container, forces occur which act both on the mounting frame and on the chassis, in such a way that resulting force components arise which can damage the chassis and / or the mounting frame.

Hinzu kommen noch die Kräfte, die von der Lagerung 14 des Abschlußdeckels, dessen Öffnungs-Zylinder-Lagerung 15 sowie von der Deckelverriegelungs-Lagerung 13 herrühren. Die genannten Elemente sind über Arme unabhängig voneinander am Außenring des Großkugellagers segmentförmig befestigt. Dies führt zu Verwindungen im Großkugellager und bedingt eine relativ schwere Bauart dieses Lagers.In addition, there are the forces resulting from the mounting 14 of the end cover, its opening-cylinder mounting 15 and from the cover locking mounting 13. The elements mentioned are attached to the outer ring of the large ball bearing in segments in the form of arms independently of one another. This leads to twists in the large ball bearing and requires a relatively heavy design of this bearing.

Auf Grund dieser Kräfte und bei Verwindungen des Fahrgestells - im unebenen Geländer beispielsweise - kommt es immer wieder zu Abweichungen zwischen der Achse des Drehtrommel-Behälters und der Achse des Antriebsaggregates. Daraus resultieren nun einerseits Verbiegungsspannungen, die gegebenenfalls zu Materialermüdungsschäden führen können. Darüberhinaus resultiert aus den Achsabweichungen eine Verringerung des Wirkungsgrades für den Drehbehälterantrieb.Due to these forces and when the chassis is twisted - in uneven railings, for example - there are always deviations between the axis of the rotating drum container and the axis of the drive unit. On the one hand, this results in bending stresses, which can lead to material fatigue damage. In addition, the axis deviations result in a reduction in efficiency for the rotary container drive.

Die der vorliegenden Erfindung zugrundeliegende Aufgabe ist es mithin, einen Drehtrommel-Sammelbehälter der eingangs genannten.Art aufzugeben, bei dem die genannten Mängel eliminiert sind. Diese Aufgabe wird dadurch gelöst, daß der-Kastenträger lose auf dem Montagerahmen aufliegt und daß die Antriebskräfte für die Drehbewegung des Behälters,The object on which the present invention is based is therefore to abandon a rotary drum collecting container of the type mentioned at the beginning, in which the above-mentioned defects are eliminated. This object is achieved in that the box girder lies loosely on the mounting frame and in that the driving forces for the rotational movement of the container,

seine Auflagekräfte und die vom als Preßschnecke wirkenden Leitblech herrührenden Preßkräfte sowie die vom Gewicht des Abschlußdeckels und der ihn betätigenden und fixierenden Elemente herrührenden Kräfte sämtlich im Kastenträger zusammengefaßt sind. Die von der Deckellagerung sowie der Lagerung der Öffnungszylinder und der Verriegelung herrührenden Krafteinleitungspunkte werden gemäß der Erfindung nicht mehr segmentförmig sondern ringförmig über den Kastenträger auf das Großkugellager geleitet.its bearing forces and the pressing forces originating from the guide plate acting as a press screw as well as the forces originating from the weight of the end cover and the elements which actuate and fix it are all combined in the box girder. According to the invention, the force introduction points originating from the cover mounting and the mounting of the opening cylinders and the locking are no longer segment-shaped, but ring-shaped via the box girder onto the large ball bearing.

Die Erfindung wird im Folgenden anhand der weiteren Zeichnungen und unter Zugrundelegung des Ausführungsbeispiels gemäß dem Unteranspruch näher erläutert.The invention is explained in more detail below on the basis of the further drawings and on the basis of the exemplary embodiment according to the subclaim.

Fig. 2 zeigt das erfindungsgemäße Konzept des Drehtrommel-Sammelbehälters in der Seitenansicht.Fig. 2 shows the inventive concept of the rotary drum collecting container in a side view.

Fig. 3 zeigt das erfindungsgemäße Konzept des Drehtrommel-. Sammelbehälters in Ansicht X ohne Deckel mit der kraftschlüssigen Verbindung der vom Eigengewicht des Aufbaus und der Nutzlast herrührenden Kräfte und der vom Antriebsritzel herrührenden Momente.Fig. 3 shows the concept of the rotary drum. Collecting container in view X without a lid with the non-positive connection of the forces resulting from the weight of the body and the payload and the moments resulting from the drive pinion.

Fig. 4 zeigt das erfindungsgemäße Konzept des Drehtrommel-Sammelbehälters im Schnitt A - B mit der kraftschlüssigen Verbindung der vom Aufbau und der Nutzlast über den Montagerahmen auf das Fahrgestell übertragenen Beschleunigungskräfte.Fig. 4 shows the concept of the rotary drum collecting container in section A - B with the non-positive connection of the acceleration forces transmitted from the body and the payload via the mounting frame to the chassis.

In Fig. 2 ist ein Drehtrommel-Sammelbehälter dargestellt, der im wesentlichen aus einem das zu sammelnde und zu transportierende Gut aufnehmenden Behälter 20 und einem Fahrgestell 21 besteht.In Fig. 2 a rotary drum collecting container is shown, which consists essentially of a container 20 to be collected and transported and a chassis 21.

Der Behälter 20 ist über ein Großkugellager 22 in einem geschlossenen zweiteiligen Kastenträger 23 gelagert. Dieser Kastenträger besteht aus einem oberen und unteren Teil, die miteinander verbunden sind. Der untere Teil des Kastenträgers 23 liegt um einen Bolzen 33 horizontal beweglich unmittelbar auf einer Platte des Montagerahmens 34 auf, der mit dem Fahrgestell 21 fest verbunden ist, wodurch die Auflagekräfte des Behälters direkt in das Fahrgestell eingeleitet werden.The container 20 is supported by a large ball bearing 22 in a closed two-part box girder 23. This box girder consists of an upper and lower part, which are connected to each other. The lower part of the box beam 23 is horizontally movable by a bolt 33 directly on a plate of the mounting frame 34 which is fixedly connected to the chassis 21, whereby the bearing forces of the container are introduced directly into the chassis.

Erfindungsgemäß werden in diesen Kastenträger 23 nun auch die obengenannten Antriebs- und Preßkräfte eingeleitet. Erstere werden über unmittelbar am unteren Teil des Kastenträgers 23 angeflanschte Antriebsmittel, im dargestellten Beispiel über einen separaten Antriebsmotor 24 für den auf dem Umfang des Behälters 20 verschweißten Zahnkranz 25 aufgenommen. Die Preßkräfte, die von dem am Abschlußdeckel 26 angebrachten Leitblech herrühren, werden über zueinander komplementäre Verriegelungsmittel 27, deren einer Bestandteil mit dem unteren Teil des Kastenträgers starr verbunden ist, auf diesen übertragen. Hinsichtlich des Antriebs für den Zahnkranz ist es auch denkbar und liegt im Rahmen der Erfindung, diesen über eine flexible Kupplung von einem Nebenantrieb des Fahrzeugantriebs anzutreiben.According to the invention, the above-mentioned drive and pressing forces are now also introduced into this box girder 23. The former are shown by means of drive means flanged directly on the lower part of the box girder 23, as shown in FIG Example added via a separate drive motor 24 for the ring gear 25 welded to the circumference of the container 20. The pressing forces, which originate from the guide plate attached to the end cover 26, are transmitted to the latter via complementary locking means 27, one component of which is rigidly connected to the lower part of the box girder. With regard to the drive for the ring gear, it is also conceivable and within the scope of the invention to drive it via a flexible coupling from a power take-off of the vehicle drive.

Der Vollständigkeit halber sei an dieser Stelle noch erwähnt, daß im oberen Teil des Kastenträgers 23 die durch ein Gelenk 29 realisierte Abschlußdeckel-Lagerung, sowie die Lagerung für die der Öffnung des Abschlußdeckels 26 dienenden Zylinder 30 angeordnet sind.For the sake of completeness, it should also be mentioned at this point that in the upper part of the box girder 23 the end cover mounting realized by a joint 29 and the mounting for the cylinder 30 serving to open the end cover 26 are arranged.

In Fig. 3 sind die im Kastenträger 23 angreifenden Elemente bzw. die von ihnen herrührenden Kräfte nochmals vergrößert aufgezeichnet.In Fig. 3 the elements acting in the box girder 23 or the forces resulting from them are recorded again enlarged.

Der durch das am unteren Teil des Kastenträgers gelagerte Ritzel 31 angetriebene Behälter 20 leitet das Drehmoment Mt über den Müll auf das Leitblech, welches mit dem Deckel 26 fest verbunden ist weiter. Der Deckel 26 wiederum überträgt das Moment auf mit der Verriegelung verbundene Zentrierungen 32 des Kastenträgers 23, wodurch sich die Momente aufheben und nicht auf den Fahrgestellrahmen 21 weitergeleitet werden.The container 20, driven by the pinion 31 mounted on the lower part of the box girder, transmits the torque M t via the garbage to the guide plate, which is firmly connected to the cover 26. The cover 26 in turn transmits the torque to the centerings 32 connected to the lock of the box girder 23, whereby the moments cancel each other out and are not passed on to the chassis frame 21.

Das vom Eigengewicht des Aufbaus und von der Nutzlast herrührende Gewicht ist mit G vektoriell angedeutet.The weight resulting from the dead weight of the body and from the payload is indicated vectorially with G.

In Fig. 4 ist das erfindungsgemäße kraftschlüssige System im Schnitt A - B nochmals im Hinblick auf die Beschleunigungs- und Verzögerungskräfte PB, die vom Eigengewicht und von der Nutzlast herrühren und über den Montagerahmen auf das Fahrgestell übertragen werden, dargestellt. Der Ableitungspunkt der Kräfte entspricht dem Bolzen 33, der die Verbindung zwischen Kastenträger und Montagerahmen darstellt.In Fig. 4, the non-positive system according to the invention is shown in section A - B again with regard to the acceleration and deceleration forces P B , which originate from the dead weight and the payload and are transmitted to the chassis via the mounting frame. The point of derivation of the forces corresponds to the bolt 33, which represents the connection between the box girder and the mounting frame.

Die erfindungsgemäße Konzeption des Kastenträgers 23 erbringt wesentlich günstigere Verhältnisse bezüglich der Kraftkomponenten, so daß eine leichtere Ausführung des Großkugellagers möglich ist. Gegenüber den bekannten Drehtrommel-Müllwagen läßt sich auf Grund der günstigeren Kräfte-Verhältnisse auch eine Reduzierung des Gewichts des Gesamt-Aufbaus erreichen. Auf Grund der Kraftschlüssigkeit von Kastenträger und Antrieb werden für den Antrieb der Trommel vom Aufbau her keine Verwindungskräfte auf den Montagerahmen und das Fahrgestell übertragen, die zu Brüchen führen können. Ergänzend sei noch darauf hingewiesen, daß auf Grund der erfindungsgemäßen Konzeption auch die von den Antriebsmitteln herrührenden Reaktionskräfte vom Kastenträger aufgenommen werden. Somit werden Montage-und Fahrgestellrahmen nicht durch diese Reaktionskräfte belastet.The concept of the box girder 23 according to the invention provides significantly more favorable conditions with regard to the force components, so that the large ball bearing can be made lighter. Compared to the known rotary drum garbage trucks, the weight of the overall structure can also be reduced due to the more favorable force ratios. Due to the frictional connection of the box girder and drive, no torsional forces are transmitted to the assembly frame and the chassis to drive the drum, which can lead to breakage. In addition, it should also be pointed out that, due to the inventive concept, the reaction forces resulting from the drive means are also absorbed by the box girder. This means that assembly and chassis frames are not burdened by these reaction forces.
