A central bearing shaft with approx. square cross section, is located coaxially to the rotary brush. It is connected on the bearing side to a bearing journal (41). The carrier elements (9) are formed as walls. The bearing-sided wall has an open mounting slot for the bearing journal.

Description

Die Erfindung betrifft eine Kehrvorrichtung für Arbeitsfahrzeuge zum Reinigen von Verkehrsflächen mit einer wenigstens einseitig motorisch rotierend angetriebenen Borstenwalze, die in einer Tragvorrichtung mit zwei seitlichen Tragelementen drehbar gelagert ist, wobei am antriebsseitigen Tragelement ein Borstenwalzenantrieb vorgesehen ist und die Borstenwalze am anderen Tragelement mittels eines Lagerzapfens in einem demontierbaren Lager drehbar gelagert ist.The invention relates to a sweeping device for work vehicles for cleaning traffic areas with a bristle roller which is driven to rotate at least on one side by a motor and which is rotatably mounted in a carrying device with two lateral support elements, a bristle roller drive being provided on the drive-side support element and the bristle roller on the other support element by means of a bearing pin in a removable bearing is rotatably mounted.

Es sind Kehrvorrichtungen der gattungsgemäßen Art bekannt, welche zum Anbau an ein Arbeitsfahrzeug vorgesehen sind. Diese Kehrvorrichtungen weisen ein Schutz- oder Traggehäuse auf, welches eine Borstenwalze zumindest oberseitig abdeckt. Im Einsatz verläuft die Borstenwalze mit ihrer Drehachse im wesentlichen quer zur Fahrtrichtung und ist im Betrieb in Umfangsrichtung entgegen der Fahrtrichtung des Arbeitsfahrzeuges motorisch rotierend angetrieben. Die Borstenwalze weist eine zentrale koaxial zur Drehachse der Borstenwalze verlaufende Lagerwelle auf, welche einstückiger Bestandteil der Borstenwalze ist. Zur Lagerung der Borstenwalze am Schutzgehäuse, ist das Schutzgehäuse mit zwei seitlichen Tragwänden versehen, wobei an der einen, antriebsseitigen Tragwand ein Borstenwalzenantrieb vorgesehen ist, mit welchem die Borstenwalze drehmomentenschlüssig gekoppelt ist. Auf der dem Borstenwalzenantrieb gegenüberliegenden Seite ist die Borstenwalze in der zweiten lagerseitigen Tragwand mittels eines Lagerzapfens in einem demontierbaren Lager drehbar gelagert.Sweeping devices of the generic type are known, which are provided for attachment to a work vehicle. These sweeping devices have a protective or carrying housing which covers a bristle roller at least on the upper side. In use, the bristle roller runs with its axis of rotation essentially transverse to the direction of travel and is in operation in the circumferential direction driven in a motor-rotating manner against the direction of travel of the work vehicle. The bristle roller has a central bearing shaft which runs coaxially to the axis of rotation of the bristle roller and which is an integral part of the bristle roller. To mount the bristle roller on the protective housing, the protective housing is provided with two lateral supporting walls, with a bristle roller drive being provided on one drive-side supporting wall, with which the bristle roller is coupled in a torque-locking manner. On the side opposite the bristle roller drive, the bristle roller is rotatably mounted in the second bearing-side support wall by means of a bearing pin in a removable bearing.

Bei den bekannten Konstruktionen durchragt die Lagerwelle der Borstenwalze im zusammengebauten Zustand die beiden Tragwände durch in den Tragwänden entsprechend vorgesehene Durchgangsbohrungen, wobei antriebsseitig in der Tragwand ebenfalls ein Lager zur drehbaren ortsfesten Lagerung der Lagerwelle vorgesehen ist. Die beiden Lager sind dabei außenseitig auf die Tragwände aufgesetzt und nehmen jeweils einen außenseitigen Lagerzapfen der Lagerwelle auf. Antriebsseitig ist die Lagerwelle dabei mit einem Kupplungszapfen versehen, welcher das antriebsseitige Lager durchragt und mit welchem die Lagerwelle über eine Kupplungsbuchse mit dem Borstenwalzenantrieb drehmomentenschlüssig verbunden ist.In the known constructions, the bearing shaft of the bristle roller projects through the two supporting walls in the assembled state through through holes provided accordingly in the supporting walls, a bearing for the rotatable, stationary mounting of the bearing shaft also being provided on the drive side. The two bearings are placed on the outside on the supporting walls and each take on an outside bearing journal of the bearing shaft. On the drive side, the bearing shaft is provided with a coupling pin which projects through the drive-side bearing and with which the Bearing shaft is torque-locked connected to the bristle roller drive via a coupling bush.

Zum Demontieren bzw. Ausbauen der Borstenwalze, was beispielsweise nach Erreichen der Verschleißgrenze notwendig ist, müssen auf beiden Seiten die Lager an den Tragwänden demontiert und antriebsseitig die zur Drehmomentenübertragung vorgesehene Kupplungsbuchse abgezogen werden. Bei einigen bekannten Kehrvorrichtungen muß zum Wechsel der Borstenwalze sogar der komplette Borstenwalzenantrieb demontiert werden. Nach dem Entfernen der Kupplungsbuchsen bzw. des Borstenwalzenantriebes und der beidseitigen Lager kann die Borstenwalze in ihrer Längsrichtung in Richtung auf den Borstenwalzenantrieb verschoben werden, so daß sie zunächst mit ihrem lagerseitigen, dem Borstenwalzenantrieb gegenüberliegenden Lagerzapfen aus der Durchgangsbohrung der lagerseitigen Tragwand herausnehmbar ist. Nach dem Verschieben der Bostenwalze in entgegengesetzter Richtung ist der antriebsseitige Lagerzaofen mit seinem Kupplungszapfen aus der Durchgangsbohrung der antriebsseitigen Tragwand herausführbar, so daß dann durch Anheben des Schutzgehäuses mit seinen beiden Tragwänden das Schutzgehäuse von der Borstenwalze entfernbar ist. Der Einbau einer neuen Borstenwalze erfolgt in entsprechend umgekehrter Reihenfolge der Arbgeitsgänge.To dismantle or remove the bristle roller, which is necessary, for example, after the wear limit has been reached, the bearings on the supporting walls must be dismantled on both sides and the coupling sleeve provided for torque transmission must be removed on the drive side. In some known sweeping devices, the entire bristle roller drive even has to be dismantled to change the bristle roller. After removing the coupling bushes or the bristle roller drive and the bearings on both sides, the bristle roller can be moved in its longitudinal direction in the direction of the bristle roller drive, so that it can first be removed from the through hole of the bearing-side support wall with its bearing-side bearing pin opposite the bristle roller drive. After moving the charge roller in the opposite direction, the drive-side storage furnace with its coupling pin can be guided out of the through hole in the drive-side supporting wall, so that the protective housing can then be removed from the bristle roller by lifting the protective housing with its two supporting walls. A new bristle roller is installed in the reverse order of the work aisles.

Desweiteren sind auch Kehrvorrichtungen bekannt, in welchen eine der Tragwände mit dem Schutzgehäuse verschraubt ist, und zum Auswechseln der Borstenwalze im Verschleißfalle beispielsweise die lagerseitige Tragwand komplett entfernt werden muß, so daß die Lagerwelle zusammen mit der Borstenwalze aus dem gegenüberliegenden, antriebsseitigen Lager herausgezogen werden kann und erst dann das Schutzgehäuse bzw. der Rest des Schutzgehäuses mit seiner zweiten Tragwand von der Borstenwalze entfernbar ist. Bei den bisher bekannten Kehrvorrichtungen ist folglich das Auswechseln einer Borstenwalze im Verschleißfalle äußerst zeitraubend und somit auch kostenintensiv.Furthermore, sweeping devices are also known, in which one of the supporting walls is screwed to the protective housing, and in order to replace the bristle roller in the event of wear, for example, the bearing-side supporting wall must be completely removed, so that the bearing shaft together with the bristle roller can be pulled out of the opposite, drive-side bearing and only then can the protective housing or the rest of the protective housing with its second supporting wall be removed from the bristle roller. In the case of the previously known sweeping devices, the replacement of a bristle roller in the event of wear is extremely time-consuming and therefore also cost-intensive.

Der Erfindung liegt die Aufgabe zugrunde, eine Kehrvorrichtung der gattungsgemäßen Art derart auszugestalten, daß ein einfaches und zeitsparendes Auswechseln von verschliessenen Borstenwalzen durchführbar ist.The invention has for its object to design a sweeping device of the generic type such that a simple and time-saving replacement of closed bristle rollers can be carried out.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Borstenwalze über eine gelenkige Wellenkupplung mit einer Antriebswelle des Borstenwalzenantriebs zur Drehmomentenübertragung verbunden ist und daß die Borstenwalze lagerseitig, einseitig zusammen mit dem und/oder ohne das Tragelement um die Wellenkupplung zur Demontage aus der Tragvorrichtung heraus verschwenkbar ist.The object is achieved in that the bristle roller is connected via an articulated shaft coupling to a drive shaft of the bristle roller drive for torque transmission and that the bristle roller on the bearing side, together with and / or without the support element around the shaft coupling Disassembly can be pivoted out of the carrying device.

Durch die erfindungsgemäße Ausgestaltung der Kehrvorrichtung ist die Borstenwalze beispielsweise nach dem Lösen des Lagers an seinem lagerseitigen Tragelement beim Anheben der Kehrvorrichtung einseitig aus der Tragvorrichtung bzw. aus dem Tragelemnt herausführbar, wobei die Borstenwalze antriebsseitig durch die gelenkige Wellenkupplung angehoben und somit um die Wellenkupplung verschenkt wird. Dadurch wird eine Schrägstellung der Borstenwalze erreicht, welche so groß ist, daß die Borstenwalze seitlich aus der Tragvorrichtung bzw. am Tragelement vorbei abziehbar ist. Die Borstenwalze wird dabei mit ihrer gelenkigen Wellenkupplung von der Antriebswelle gezogen, so daß die Borstenwalze freiliegt und gegen eine neue Borstenwalze ersetzt werden kann.Due to the design of the sweeping device according to the invention, the bristle roller can be guided out of the carrying device or from the supporting element on one side, for example after the bearing on its bearing-side support element has been lifted, when the sweeping device is lifted, the bristle roller being raised on the drive side by the articulated shaft coupling and thus being given away around the shaft coupling . This results in an inclined position of the bristle roller which is so large that the bristle roller can be pulled off laterally from the carrying device or past the carrying element. The bristle roller is pulled with its articulated shaft coupling from the drive shaft so that the bristle roller is exposed and can be replaced with a new bristle roller.

Beim Einbau wird zunächst die Borstenwalze mit ihrer Wellenkupplung auf die Antriebswelle geschoben, wobei die Tragvorrichtung angehoben ist. Beim Absenken des Antriebsgehäuses schiebt sich das lagerseitige Tragelement wieder über den Lagerbolzen bzw. über das Lager der Borstenwalze, so daß bei vollständig abgesenkter Kehrvorrichtung nur noch das Lager montiert bzw. an seinem Tragelement befestigt werden muß und somit der Austausch der Borstenwalze vollzogen ist.When installing, the bristle roller with its shaft coupling is first pushed onto the drive shaft, with the support device being raised. When lowering the drive housing, the bearing-side support element is pushed back over the bearing pin or over the bearing of the bristle roller, so that when the sweeper is completely lowered, only the bearing has to be mounted or fastened to its support element and the exchange of the bristle roller is thus completed.

Durch die Ausgestaltungen gemäß der Ansprüche 2 und 3 wird das Auswechseln der Borstenwalze dahingehend vereinfacht, daß die vorgesehene koaxial zur Borstenwalze verlaufende Lagerwelle selbst nicht mehr ausgewechselt werden muß, da auf dieser der Walzenzylinder mit seinen Walzenborsten auswechselbar aufgeschoben ist. Dies hat insbesondere bei der Montage der neuen Borstenwalze bzw. der neuen Walzenzylinder den Vorteil, daß die gelenkige Wellenkupplung nicht auf die Antriebswelle aufgefädelt werden muß, sondern durch einfaches Aufschieben des neuen Walzenzylinders mit seinen radialen Walzenborsten auf die Lagerwelle der Austausch der Borstenwalze erfolgt. Zur Drehmomentenübertragung von der Lagerwelle auf den Walzenzylinder der Borstenwalze weist der Walzenzylinder wenigstens im Bereich seiner Enden Lagerscheiben auf, welche jeweils einen Durchbruch aufweisen, dessen Querschnitt dem Querschnittsprofil der Lagerwelle angepaßt ist. Der Lagerwellenquerschnitt kann dabei beispielsweise quadratisch ausgebildet sein, so daß eine formschlüssige Verbindung zwischen den Lagerscheiben und der Lagerwelle gebildet wird und damit eine Drehmomentenübertragung von der Lagerwelle auf den Walzenzylinder mit seinen Walzenborsten sichergestellt ist.The configurations according to claims 2 and 3 simplify the replacement of the bristle roller in such a way that the bearing shaft provided which runs coaxially to the bristle roller itself no longer has to be replaced, since the roller cylinder with its roller bristles is interchangeably slid onto it. This has the advantage in particular when installing the new bristle roller or the new roller cylinder that the articulated shaft coupling does not have to be threaded onto the drive shaft, but is simply replaced by simply pushing the new roller cylinder with its radial roller bristles onto the bearing shaft to replace the bristle roller. For torque transmission from the bearing shaft to the roller cylinder of the bristle roller, the roller cylinder has bearing disks at least in the region of its ends, each of which has an opening, the cross section of which is adapted to the cross-sectional profile of the bearing shaft. The cross section of the bearing shaft can be square, for example, so that a positive connection is formed between the bearing washers and the bearing shaft and thus a torque transmission from the bearing shaft to the roller cylinder with its roller bristles is ensured.

Gemäß Anspruch 4 ist zum einfachen einseitigen Herausführen des Lagerzapfens der Borstenwalze in dem beispielsweise als Tragwand ausgebildeten Tragelement ein seitlich oder nach unten offener Montageschlitz vorgesehen, so daß nach dem Lösen des Lagers der Lagerzapfen zusammen mit seinem Lager oder nach Abziehen des Lagers in einfacher Weise aus dem Montageschlitz herausführbar ist und beim Anheben der Kehrvorrichtung aus der Tragvorrichtung herausgeführt wird.According to claim 4 is for easy one-sided removal of the journal of the bristle roller in the for example, a support element designed as a support wall, a laterally or downwardly open mounting slot is provided, so that after loosening the bearing the bearing pin together with its bearing or after removing the bearing can be easily removed from the mounting slot and is removed from the carrying device when the sweeping device is lifted .

Zur Sicherung des Walzenzylinders auf der Lagerwelle ist die Lagerwelle einerseits im Bereich der Wellenkupplung mit einer Anschlagscheibe versehen, gegen welchen der Walzenzylinder bei der Montage geschoben wird. Zum Fixieren des Walzenzylinders auf der Lagerwelle auf dem dem Anschlagflansch gegenüberliegenden, lagerseitigen Ende der Borstenwalze ist eine Haltescheibe vorgesehen, welche beispielsweise mittels Klemmschrauben auf der Lagerwelle in entsprechender Lage fixierbar ist.To secure the roller cylinder on the bearing shaft, the bearing shaft is provided on the one hand in the area of the shaft coupling with a stop disk against which the roller cylinder is pushed during assembly. In order to fix the roller cylinder on the bearing shaft on the bearing-side end of the bristle roller opposite the stop flange, a holding disc is provided, which can be fixed in a corresponding position, for example by means of clamping screws, on the bearing shaft.

Die in Fig., 1 dargestellte Kehrvorrichtung 1 weist eine Borstenwalze 2 auf, welche über einen Borstenwalzenantrieb 3 rotierend angetreibbar ist. Der Borstenwalzenantrieb 3 besteht aus einem Antriebsgetriebe 4, welches in Höhe der Drehachse 5 der Borstenwalze 2 eine Antriebswelle 6 aufweist. Die Kehrvorrichtung 1 weist eine Tragvorrichtung 50 mit zwei seitlichen Tragelementen in Form von Tragwänden 7, 9 auf. Das Antriebsgetriebe 4 ist an seiner antriebsseitigen Tragwand 7 außenseitig angeordnet, wobei die Tragwand 7 Bestandteil eines Schutzgehäuses 8 ist, welches die Borstenwalze 2 oberseitig abdeckt. Das Schutzgehäuse 8 weist auf seiner dem Borstenwalzenantrieb 3 gegenüberliegenden Stirnseite eine zweite Tragwand 9 auf, welche in ihrem unteren Endbereich ein Lager 10 zur drehbaren Lagerung der Borstenwalze 2 aufweist. Zur Stabilisierung des Schutzgehäuses ist oberseitig ein Trägerrohr 11 vorgesehen, welches die beiden Tragwände 7 und 8 parallel zur Drehachse 5 der Borstenwalze 2 verlaufend miteinander verbindet. Der Antrieb der Borstenwalze 2 erfolgt mittels eines Hydromotors (in derThe sweeping device 1 shown in FIG. 1 has a bristle roller 2 which can be driven in rotation via a bristle roller drive 3. The bristle roller drive 3 consists of a drive gear 4 which has a drive shaft 6 at the axis of rotation 5 of the bristle roller 2. The sweeping device 1 has a carrying device 50 with two lateral carrying elements in the form of carrying walls 7, 9. The drive gear 4 is arranged on its drive-side support wall 7 on the outside, the support wall 7 being part of a protective housing 8 which covers the bristle roller 2 on the upper side. The protective housing 8 has on its end face opposite the bristle roller drive 3 a second support wall 9, which has a bearing 10 in its lower end region for the rotatable mounting of the bristle roller 2. To stabilize the protective housing, a support tube 11 is provided on the upper side, which connects the two supporting walls 7 and 8 to one another, running parallel to the axis of rotation 5 of the bristle roller 2. The bristle roller 2 is driven by means of a hydraulic motor (in the

Zeichnung nicht dargestellt) oder von der Zapfwelle eines Antriebsfahrzeuges, wobei das Drehmoment über einen Antriebszapfen 12 auf das Antriebsgetriebe 4 und von dort auf die Antriebswelle 6 und damit auf die Borstenwalze 2 übertragen wird. Die Borstenwalze 2 ist im vorliegenden Ausführungsbeispiel aus drei separaten Walzenabschnitten 13, 14, 15 gebildet, welche jeweils aus einem Walzenzylinder 16, 17, 18 mit radial zur Drehachse 5 verlaufenden Walzenborsten 19, 20, 21 bestehen. Die Walzenzylinder 16, 17, 18 sind an ihren jeweiligen stirnseitigen Endbereichen jeweils mit einer Lagerscheibe 22, 23 bzw. 24, 25 bzw. 26, 27 versehen, wobei die Lagerscheibe 27 zur Aufnahme einer gelenkigen Wellenkupplung 28 im Walzenzylinder 18 im Abstand von der antriebsseitigen Stirnseite 29 des Walzenabschnittes 15 im Walzenzylinder 18 angeordnet ist.Drawing not shown) or from the PTO of a drive vehicle, the torque is transmitted via a drive pin 12 to the drive gear 4 and from there to the drive shaft 6 and thus to the bristle roller 2. In the present exemplary embodiment, the bristle roller 2 is formed from three separate roller sections 13, 14, 15, each of which consists of a roller cylinder 16, 17, 18 with roller bristles 19, 20, 21 running radially to the axis of rotation 5. The roller cylinders 16, 17, 18 are each provided with a bearing plate 22, 23 or 24, 25 or 26, 27 at their respective end regions, the bearing plate 27 for receiving an articulated shaft coupling 28 in the roller cylinder 18 at a distance from the drive side End face 29 of the roller section 15 is arranged in the roller cylinder 18.

Die Lagerscheiben 22 bis 27 sind zusammen mit ihren Walzenzylindern 16, 17, 18 auf eine Lagerwelle 30 aufgeschoben, welche im vorliegenden Ausführungsbeispiel als Vierkantrohr ausgebildet ist und von den Lagerscheiben 22 bis 27 entsprechend formschlüssig umschlossen ist. Die Walzenabschnitte 13, 14, 15 sind mit ihren Lagerscheiben 22 bis 27 auf die Lagerwelle 30 aufschiebbar, wobei am antriebsseitigen Ende der Lagerwelle 30 ein Anschlagflansch 31 vorgesehen ist. Antriebsseitig ist am Anschlagflansch 31 drehmomentschlüssig eine gelenkige Wellenkupplung in Form eines Kreuzgelenkes 32 angeschraubt.The bearing disks 22 to 27 are pushed together with their roller cylinders 16, 17, 18 onto a bearing shaft 30, which in the present exemplary embodiment is designed as a square tube and is correspondingly positively enclosed by the bearing disks 22 to 27. The roller sections 13, 14, 15 with their bearing disks 22 to 27 can be pushed onto the bearing shaft 30, a stop flange 31 being provided at the drive-side end of the bearing shaft 30. The drive side is on the stop flange 31 torque-wise screwed an articulated shaft coupling in the form of a universal joint 32.

Die Walzenabschnitte 13, 14, 15 sind auf der Lagerwelle mittels einer Haltescheibe 42 in axialer Richtung unverschiebbar gehalten, wobei die Haltescheibe 42 beispielsweise mittels Klemmschrauben auf der Lagerwelle 30 fixierbar sein kann. Bei gelösten Klemmschrauben ist die Haltescheibe 42 selbstverständlich bei freiem Ende der Lagerwelle 30 von dieser abziehbar.The roller sections 13, 14, 15 are held immovably on the bearing shaft by means of a retaining disk 42 in the axial direction, the retaining disk 42 being able to be fixed on the bearing shaft 30, for example, by means of clamping screws. When the clamping screws are loosened, the retaining washer 42 can of course be removed from the bearing shaft 30 with the free end thereof.

Fig. 2 zeigt einen vergrößerten Ausschnitt III aus Fig. 1, in welchem der Walzenabschnitt 15 im Schnitt dargestellt ist. Aus Gründen der Übersichtlichkeit ist das Antriebsgetriebe 4 nicht geschnitten dargestellt. Im antriebsseitigen Endabschnitt des Walzenzylinders 18 des Walzenabschnittes 15 ist die Lagerscheibe 27 angeordnet, welche einen Durchbruch 33 aufweist, der einen quadratischen Querschnitt aufweist und die im Querschnitt quadratische Lagerwelle 30 annähernd spielfrei umschließt. Die Lagerwelle 30 durchragt die Lagerscheibe 27 antriebsseitig und ragt in den Anschlagflansch 31 in einen entsprechend vorgesehenen Durchbruch 34 des Anschlagflansches 31. Im Durchbruch 34 ist die Lagerwelle 30 mit dem Anschlagflansch 31 verschweißt, wobei antriebsseitig das Kreuzgelenk 32 mit einem Montageflansch 35 auf den Anschlagflansch 31 aufgeschraubt ist. Das Kreuzgelenk 32 ist mit seiner getriebeseitigen Lagerhülse 36 auf eine entsprechende Verzahnung 37 der Antriebswelle 36 aufgeschoben und auf diesem mittels eines die Lagerhülse 36 und die Antriebswelle 6 gemeinsam durchragenden Sicherungsstift 37 axial unverschieblich gesichert.FIG. 2 shows an enlarged section III from FIG. 1, in which the roller section 15 is shown in section. For reasons of clarity, the drive gear 4 is not shown in section. In the drive-side end section of the roller cylinder 18 of the roller section 15, the bearing disk 27 is arranged, which has an opening 33, which has a square cross section and encloses the bearing shaft 30, which is square in cross section, with almost no play. The bearing shaft 30 projects through the bearing disk 27 on the drive side and projects into the stop flange 31 into a correspondingly provided opening 34 in the stop flange 31. In the opening 34, the bearing shaft 30 is welded to the stop flange 31, the universal joint 32 on the drive side having a mounting flange 35 on the stop flange 31 is screwed on. The universal joint 32 is pushed with its gear-side bearing sleeve 36 onto a corresponding toothing 37 of the drive shaft 36 and axially immovably secured thereon by means of a locking pin 37 projecting through the bearing sleeve 36 and the drive shaft 6.

Die Lagerhülse 36 des Kreuzgelenkes weist ein U-förmig ausgebildetes Gabelelement 38 auf, welches mit einem entsprechenden Gabelelement 39 des Montageflansches 35 schwenkbar verbunden ist. Die beiden Gabelelemente 38, 39 sind dabei gegeneinander um zwei senkrecht zueinander verlaufende Schwenkachsen schwenkbar, so daß auch die Lagerwelle 30, welche am Montageflansch 35 fest angeschraubt ist gegenüber der Lagerhülse 36 und damit auch gegenüber der Antriebswelle 6 des Antriebsgetriebes 4 frei schwenkbar ist. Durch den Sicherungsstift 37 und die Verschraubung des Montageflansches 35 ist die Lagerwelle 30 axial unverschieblich gegenüber der Antriebswelle 6 bzw. gegenüber dem Antriebsgetriebe 4 und somit auch gegenüber dem Schutzgehäuse 8, dessen antriebsseitige Tragwand 7 in Fig. 2 erkennbar ist.The bearing sleeve 36 of the universal joint has a U-shaped fork element 38 which is pivotally connected to a corresponding fork element 39 of the mounting flange 35. The two fork elements 38, 39 are mutually pivotable about two mutually perpendicular pivot axes, so that the bearing shaft 30, which is screwed to the mounting flange 35 against the bearing sleeve 36 and thus also against the drive shaft 6 of the drive gear 4 is freely pivotable. Due to the locking pin 37 and the screwing of the mounting flange 35, the bearing shaft 30 is axially immovable with respect to the drive shaft 6 or with respect to the drive gear 4 and thus also with respect to the protective housing 8, the drive-side support wall 7 of which can be seen in FIG. 2.

Lagerseitig ist auf der Tragwand 9 des Schutzgehäuses 8 das Lager 10 außenseitig aufgesetzt und mittels Schraubverbindungen auf der Tragwand 9 verschraubt.On the bearing side, the bearing 10 is placed on the outside on the supporting wall 9 of the protective housing 8 and screwed onto the supporting wall 9 by means of screw connections.

Wie aus Fig. 3 ersichtlich ist, ist die Tragwand 9 vertikal unterhalb des Lagers 10 mit einem vertikal nach unten offenen Montageschlitz 40 versehen. Die Lagerwelle 30 weist lagerseitig einen Lagerzapfen 41 auf, mit welchem sie den Montageschlitz 40 durchragt und außenseitig auf die Tragwand 9 des aufgeschraubten Lagerhäuses des Lagers 10 drehbar beispielsweise mittels eines Wälzlagers gelagert ist. Durch den Montageschlitz 40 wird erreicht, daß bei gelöstem und eventuell vom Lagerzapfen 41 abgezogenem Lager 10 die Lagerwelle 30 mit ihrem Lagerzapfen 41 aus dem Montageschlitz und damit aus dem Schutzgehäuse 8 bzw. der Tragwand 9 herausführbar ist, sofern die Kehrvorrichtung 1 vom Untergrund 43 angehoben wird, wie dies in Fig. 4 dargestellt ist.As can be seen from FIG. 3, the supporting wall 9 is provided vertically below the bearing 10 with a mounting slot 40 which is open vertically downwards. The bearing shaft 30 has a bearing pin 41 on the bearing side, with which it extends through the mounting slot 40 and is rotatably supported on the outside on the supporting wall 9 of the screwed-on bearing housing of the bearing 10, for example by means of a roller bearing. The mounting slot 40 ensures that when the bearing 10 is loosened and possibly removed from the bearing pin 41, the bearing shaft 30 with its bearing pin 41 can be guided out of the mounting slot and thus out of the protective housing 8 or the supporting wall 9, provided that the sweeping device 1 is lifted from the surface 43 becomes, as shown in Fig. 4.

Durch die Nachgiebigkeit der Walzenborsten 21 im linken oberen Bereich des Schutzgehäuses 8 wird ein Verschwenken der Lagerwelle 30 und damit der gesamten Borstenwalze 2 soweit ermöglicht, daß bei entferntem Lager 10 und entfernter Haltescheibe 42 die Walzenabschnitte 13, 14, 15 nacheinander von der Lagerwelle 30 unterhalb der lagerseitigen Tragwand 9 abziehbar sind und durch entsprechend neue Walzenabschnitte ersetzbar sind. Die Walzenborsten 21 werden dabei in dieser Stellung, wie aus Fig. 4 ersichtlich ist, im linken oberen Bereich des Schutzgehäuses 8 einfach zusammengedrückt.The flexibility of the roller bristles 21 in the upper left area of the protective housing 8 enables the bearing shaft 30 and thus the entire bristle roller 2 to be pivoted so far that the roller sections 13, 14, 15 in succession from the bearing shaft 30 below when the bearing 10 and the holding disc 42 are removed the bearing-side support wall 9 are removable and can be replaced by corresponding new roller sections. The roller bristles 21 are simply pressed together in this position, as can be seen in FIG. 4, in the upper left area of the protective housing 8.

Es ist auch möglich, daß das Kreuzgelenk 32 mit seiner Lagerhülse 36 auf der Antriebswelle 6 des Antriebsgetriebes 4 axial verschieblich gelagert ist, d.h. das kein Sicherungsstift 37 vorgesehen ist, so daß die Lagerwelle zusammen mit den Walzenabschnitten 13, 14, 15 d.h. also die gesamte Borstenwalze 2 mit dem kompletten Kreuzgelenk 32 von der Antriebswelle 6 aus der in Fig. 4 gezeigten Lage abziehbar ist und frei liegt, so daß erst anschließend durch einfaches Ausziehen der Lagerwelle 30 aus den Walzenabschnitten 13, 14, 15 diese durch entsprechend neues Auffädeln der neuen Walzenabschnitte auf die Lagerwelle 30 ersetzbar sind.It is also possible for the universal joint 32 with its bearing sleeve 36 to be axially displaceably mounted on the drive shaft 6 of the drive gear 4, i.e. that no locking pin 37 is provided, so that the bearing shaft together with the roller sections 13, 14, 15 i.e. So the entire bristle roller 2 with the complete universal joint 32 can be removed from the drive shaft 6 from the position shown in FIG. 4 and is exposed, so that only then by simply pulling out the bearing shaft 30 from the roller sections 13, 14, 15 does this by a correspondingly new one Threading the new roller sections on the bearing shaft 30 are replaceable.

Durch anschließendes Absenken der Kehrvorrichtung 1 bzw. des Schutzgehäuses 8 umgreift der Montageschlitz 40 bei entsprechender Positionierung des Lagerzapfens 41 diesen, so daß das Lager 10 auf den Lagerzapfen 41 aufschiebbar ist und entsprechend an der Außenseite der lagerseitigen Tragwand 9 verschraubbar ist.Subsequent lowering of the sweeping device 1 or the protective housing 8 engages around the mounting slot 40 when the bearing pin 41 is positioned accordingly, so that the bearing 10 can be pushed onto the bearing pin 41 and can accordingly be screwed onto the outside of the bearing wall 9 on the bearing side.

Fig. 5 zeigt einen Schnitt V-V aus Fig. 4 in welchem erkennbar ist, daß die Lagerscheibe 25 spielfrei festsitzend im Walzenzylinder 17 des Walzenabschnittes 15 angeordnet ist. Die Lagerscheibe 25 weist einen quadratischen Durchbruch 43 auf, welcher passend aber axial verschiebbar die Lagerwelle 30, deren quadratischer Querschnitt ebenfalls in Fig. 5 erkennbar ist umschließt.FIG. 5 shows a section VV from FIG. 4 in which it can be seen that the bearing disk 25 is arranged in the roller cylinder 17 of the roller section 15 without play and without play. The bearing disk 25 has a square opening 43, which fits the bearing shaft 30 in a suitable but axially displaceable manner, the square cross section of which can also be seen in FIG. 5.

In gleicher Weise wie die Lagerscheibe 25 sind auch die weiteren Lagerscheiben 22, 23, 24, 26 und 27, wie in Fig. 1. gestrichelt bzw. in Fig. 4 im Schnitt dargestellt, ausgebildet, so daß das über die Antriebswelle 6 und das Kreuzgelenk 32 in die Lagerwelle 30 eingeleitete Antriebsdrehmoment sicher über die Lagerscheiben 22 bis 27 auf die entsprechenden Walzenzylinder 16, 17, 18 und damit auf deren Walzenborsten 19, 20 bzw. 21 übertragen wird.In the same way as the bearing disk 25, the other bearing disks 22, 23, 24, 26 and 27 are formed, as shown in broken lines in FIG. 1 or shown in section in FIG. 4, so that the drive shaft 6 and the Universal joint 32 drive torque introduced into the bearing shaft 30 is transmitted securely via the bearing disks 22 to 27 to the corresponding roller cylinders 16, 17, 18 and thus to their roller bristles 19, 20 and 21, respectively.

Durch die erfindungsgemäße Ausgestaltung der Kehrvorrichtung 1 ist ein einfaches Austauschen einer verschließenen Borstenwalze 2 durchführbar. Es versteht sich, daß anstatt der drei Walzenabschnitte 13, 14, 15 auch ein einstückig ausgebildeter Walzenabschnitt, welcher sich über die gesamte Breite der Kehrvorrichtung 1 erstreckt vorgesehen sein kann.The configuration of the sweeping device 1 according to the invention makes it easy to replace a closed bristle roller 2. It goes without saying that instead of the three roller sections 13, 14, 15, there is also a one-piece roller section which can be provided over the entire width of the sweeping device 1.

Desweiteren ist auch vorgesehen, daß der Montageschlitz 40 horizontal verläuft, so daß nach dem Lösen und Abnehmen des Lagers 10 vom Lagerzapfen 41 der Wellenzapfen bzw. die Lagerwelle 30 zunächst horizontal aus dem Montageschlitz 40 geführt wird, bevor die Borstenwalze 2 einseitig absenkbar ist, wenn die Kehrvorrichtung 1 angehoben wird.Furthermore, it is also provided that the mounting slot 40 runs horizontally, so that after loosening and removing the bearing 10 from the journal 41 of the shaft journal or the bearing shaft 30 is first guided horizontally out of the mounting slot 40 before the bristle roller 2 can be lowered on one side if the sweeper 1 is raised.

Es ist auch vorstellbar, daß das Lager 10 auf der Innenseite der lagerseitigen Tragwand 9 angeordnet ist, wobei in diesem Falle nicht zwingend ein Montageschlitz 40 vorgesehen sein muß, daß das Lager 10 nach dessen Lösen mit dem Lagerzapfen 41 entlang der Innenseite der Tragwand 9 beim Anheben der Kehrvorrichtung 1 nach außen herausführbar ist. Der vorgesehene Montageschlitz 40 hat allerdings den Vorteil, daß bei entsprechender Ausbildung des Lagergehäuses des Lagers 10 mit einem in den Montageschlitz 40 entsprechend passend einsetzbaren Gehäuseabschnitt, das Lager 10 und damit die Borstenwalze 2 definiert zentriert an der Tragwand 9 gehalten ist.It is also conceivable that the bearing 10 is arranged on the inside of the bearing wall 9, in this case, it is not absolutely necessary to provide a mounting slot 40 that the bearing 10 can be guided outwards after the loosening of the bearing pin 41 along the inside of the supporting wall 9 when the sweeping device 1 is lifted. The provided mounting slot 40 has the advantage, however, that with a corresponding design of the bearing housing of the bearing 10 with a housing section that can be inserted into the mounting slot 40 accordingly, the bearing 10 and thus the bristle roller 2 are held in a defined center on the supporting wall 9.

Desweiteren kann das Lagergehäuse des Lagers 10 auch fest mit der der Tragwand 9 verschweißt sein, so daß zum verschwenken der Borstenwalze 2 aus der Tragvorrichtung 50 heraus die Tragwand 9 an der Tragvorrichtung 50 bzw. an dessen Trägerrohr 11 lösbar angeschraubt ist und vor dem Verschwenken abgeschraubt wird. Die Borstenwalze 2 wird dann zusammen mit der Tragwand 9 und mit dem Lager 10 aus der Tragvorrichtung 50 heraus verschwenkt, das Lager 10 demontiert und die Borstenwalze 2 durch eine neue Borstenwalze ersetzt.Furthermore, the bearing housing of the bearing 10 can also be firmly welded to that of the support wall 9, so that for pivoting the bristle roller 2 out of the support device 50 the support wall 9 is detachably screwed to the support device 50 or to its support tube 11 and unscrewed before pivoting becomes. The bristle roller 2 is then pivoted out of the carrying device 50 together with the support wall 9 and with the bearing 10, the bearing 10 is dismantled and the bristle roller 2 is replaced by a new bristle roller.

Ein weiterer Vorteil des vorgesehenen Kreuzgelenkes 32 besteht darin, daß eine 100%-e koaxiale Ausrichtung der Antriebswelle 6 des Antriebsgetriebes 4 und der Lagerwelle 30 im Betriebstzustand, d.h. in zusammengebautem Zustand nicht erfordelich ist, da derartige Winkelabweichungen vom koaxialen Verlauf der Antriebswelle 6 zur Lagerwelle 30 vom Kreuzgelenk 32 ausgeglichen werden. Anstatt des Kreuzgelenkes 32 sind auch noch weitere bekannte gelenkige Wellenkupplungen, wie z.B. Gleichlaufgelenke und dgl. vorstellbar.Another advantage of the universal joint 32 provided is that a 100% coaxial alignment of the drive shaft 6 of the drive gear 4 and the bearing shaft 30 in the operating state, ie in the assembled state, is not necessary because Such angular deviations from the coaxial course of the drive shaft 6 to the bearing shaft 30 are compensated for by the universal joint 32. Instead of the universal joint 32, other known articulated shaft couplings, such as constant velocity joints and the like, are also conceivable.
