Description

Die Erfindung betrifft eine Kehrmaschine, umfassend eine angetriebene Kehrwalze und einen Kehrwalzenträger, an dem zwei Lagerteile angeordnet sind, an welchen die Kehrwalze drehbeweglich gehalten ist, wobei die Lagerteile mit der Federkraft eines sich an der Kehrwalze in axialer Richtung abstützenden elastischen Elementes beaufschlagt sind, wobei mindestens einem der Lagerteile mindestens ein Stützglied zur Ableitung der auf das mindestens eine Lagerteil wirkenden Federkraft an den Kehrwalzenträger zugeordnet ist.The invention relates to a sweeping machine, comprising a driven sweeping roller and a Kehrwalzenträger on which two bearing parts are arranged, on which the sweeping roller is rotatably supported, wherein the bearing parts are acted upon by the spring force of a on the sweeping roller in the axial direction supporting elastic element at least one of the bearing parts at least one support member for deriving the force acting on the at least one bearing part spring force is assigned to the broom carrier.

Bei Kehrmaschinen, bei denen die Kehrwalze zwischen den Lagerteilen angeordnet ist, besteht das Problem, dass die mit der Federkraft beaufschlagten Lagerteile auseinandergedrückt werden. Dies kann dazu führen, dass die Lagerteile die Kehrwalze unerwünscht freigeben.In sweepers in which the sweeping roller is arranged between the bearing parts, there is the problem that the bearing acted upon by the spring force bearing parts are forced apart. This can lead to the bearing parts unwanted release the sweeping roller.

Die DE 198 20 628 C1 beschreibt eine Kehrmaschine mit einer rotierend antreibbaren Bürstenwalze, die an beiden Enden in einem Rahmen drehbar gelagert ist und die über ein an einem Ende mit seinen Zähnen in Mitnahmeausnehmungen in der Bürstenwalze eingreifendes Zahnrad angetrieben wird, welches die Lagerung der Bürstenwalze an diesem Ende bildet. Zum Ausbau der Bürstenwalze kann diese gegen die Wirkung einer Feder in axialer Richtung so weit gegen das Zahnrad verschoben werden, dass die Lagerung der Bürstenwalze auf der dem Zahnrad gegenüberliegenden Ende außer Eingriff gelangt, woraufhin die Bürstenwalze mit ihrem dem Zahnrad gegenüberliegenden Ende aus dem Bereich der Lagerung herausschwenkbar ist.The DE 198 20 628 C1 describes a sweeper with a rotatably driven brush roller, which is rotatably mounted at both ends in a frame and which is driven via a at one end with its teeth in Mitnahmeausnehmungen in the brush roller engaging gear, which forms the bearing of the brush roller at this end. To remove the brush roller, it can be moved so far against the action of a spring in the axial direction against the gear that the bearing of the brush roller on the opposite end of the gear wheel is disengaged, whereupon the brush roller with its end opposite the gear from the field of Storage is swung out.

In der DE 1 728 324 ist eine Vorrichtung zur auswechselbaren Befestigung einer rotierenden Bearbeitungswalze an einer elektromotorisch angetriebenen Fußbodenreinigungs- und Pflegemaschine beschrieben. Die Vorrichtung umfasst axial verschiebliche, die Bearbeitungswalze haltende Lagerzapfen.In the DE 1 728 324 is a device for interchangeable attachment of a rotating machining roller to an electric motor driven floor cleaning and maintenance machine described. The device comprises axially displaceable bearing journals holding the machining roller.

Aufgabe der vorliegenden Erfindung ist es, eine gattungsgemäße Kehrmaschine bereitzustellen, bei der die Gefahr des unerwünschten Freigebens der Kehrwalze vermindert ist.Object of the present invention is to provide a generic sweeper, wherein the risk of unwanted release of the sweeping roller is reduced.

Diese Aufgabe wird bei einer Kehrmaschine der eingangs genannten Art erfindungsgemäß dadurch gelöst, dass die Lagerteile am Kehrwalzenträger zum Absenken und/oder Anheben der Kehrwalze relativ zu einer Aufstellfläche der Kehrmaschine verstellbar sind und dass das mindestens eine Stützglied und das mindestens eine ihm zugeordnete Lagerteil eine Führung definieren, in die der Kehrwalzenträger abschnittsweise eingreift.This object is achieved in a sweeper of the type mentioned in the present invention that the bearing parts are adjustable on the broom carrier for lowering and / or lifting the sweeping roller relative to a footprint of the sweeper and that the at least one support member and the at least one associated bearing part a guide define, in which the broom carrier engages in sections.

Mittels des mindestens einen Stützgliedes kann sich das mindestens eine Lagerteil am Kehrwalzenträger abstützen und dadurch die Federkraft an den Kehrwalzenträger ableiten. Dies verringert die Gefahr, dass die Lagerteile durch die Federkraft auseinandergedrückt werden. Dementsprechend ist die Gefahr vermindert, dass die Kehrwalze unerwünscht freigegeben wird.By means of the at least one support member, the at least one bearing part can be supported on the broom carrier and thereby derive the spring force to the broom carrier. This reduces the risk that the bearing parts are forced apart by the spring force. Accordingly, the risk is reduced that the sweeping roller is released undesirable.

Es kann vorgesehen sein, dass dem mindestens einen Lagerteil eine Mehrzahl von Stützgliedern zur Ableitung der Federkraft an den Kehrwalzenträger zugeordnet ist.It can be provided that the at least one bearing part is assigned a plurality of support members for deriving the spring force to the broom carrier.

Die Lagerteile sind am Kehrwalzenträger zum Absenken und/oder Anheben der Kehrwalze relativ zu einer Aufstellfläche der Kehrmaschine verstellbar. Dies gibt die Möglichkeit, den Abstand der Kehrwalze relativ zur Aufstellfläche unterschiedlich einzustellen. Dies ist beispielsweise bei Abnutzung der Kehrwalze von Vorteil. Es kann auch vorgesehen sein, dass mit der Kehrmaschine unterschiedliche Kehrwalzen je nach zu reinigender Aufstellfläche zum Einsatz kommen, die bezüglich der Aufstellfläche unterschiedliche Abstände erfordern.The bearing parts are adjustable on the broom carrier for lowering and / or lifting the sweeping roller relative to a footprint of the sweeper. This makes it possible to adjust the distance of the sweeping roller relative to the footprint differently. This is for example when wearing the sweeping roller advantage. It can also be provided that different sweeping rollers are used depending on the cleaning surface to be cleaned with the sweeper, which require different distances with respect to the footprint.

Das mindestens eine Stützglied und das mindestens eine ihm zugeordnete Lagerteil definieren eine Führung, in die der Kehrwalzenträger abschnittsweise eingreift. Mittels einer derartigen Führung kann eine Bewegung und insbesondere eine Verschwenkung des mindestens einen Lagerteiles relativ zum Kehrwalzenträger, mit der ein Absenken und/oder Anheben der Kehrwalze ermöglicht wird, geführt werden. Die Gleichförmigkeit der Bewegung des mindestens einen Lagerteiles kann dadurch auf einfache Weise sichergestellt werden.The at least one support member and the at least one bearing part assigned to it define a guide into which the broom carrier engages in sections. By means of such a guide movement and in particular a pivoting of the at least one bearing part relative to the broom carrier, with the lowering and / or lifting of the sweeping roller is made possible, are performed. The uniformity of the movement of the at least one bearing part can be ensured in a simple manner.

Vorzugsweise ist beiden Lagerteilen jeweils mindestens ein Stützglied zur Ableitung der auf sie wirkenden Federkraft an den Kehrwalzenträger zugeordnet. Dies erlaubt es, dass sich beide Lagerteile an dem Kehrwalzenträger abstützen. Damit kann weitgehend verhindert werden, dass die Lagerteile aufgrund der Federkraft des elastischen Elementes auseinandergedrückt werden, und die Gefahr einer unbeabsichtigten Freigabe der Kehrwalze ist weiter vermindert.Preferably, at least one support member for deriving the force acting on it spring force is assigned to the broom carrier in each case two bearing parts. This allows both bearing parts to be supported on the broom carrier. This can largely be prevented that the bearing parts are forced apart due to the spring force of the elastic element, and the risk of unintentional release of the sweeping roller is further reduced.

Günstig ist es, wenn das mindestens eine Stützglied an dem mindestens einen Lagerteil festgelegt ist und an dem Kehrwalzenträger anliegt. Dadurch ist eine konstruktiv einfache Möglichkeit gegeben, die Federkraft an den Kehrwalzenträger abzuleiten.It is advantageous if the at least one support member is fixed to the at least one bearing part and bears against the broom carrier. This provides a structurally simple way to derive the spring force to the broom carrier.

Ebenso kann vorgesehen sein, dass das mindestens eine Stützglied an dem Kehrwalzenträger festgelegt ist und an dem mindestens einen Lagerteil zur Ableitung der Federkraft an den Kehrwalzenträger anliegt.Likewise, it can be provided that the at least one support member is fixed to the broom carrier and rests on the at least one bearing part for deriving the spring force to the broom carrier.

Sind dem mindestens einen Lagerteil mehrere Stützglieder zugeordnet, kann auch vorgesehen sein, dass mindestens ein erstes Stützglied am Kehrwalzenträger festgelegt ist und an dem mindestens einen Lagerteil anliegt und dass mindestens ein zweites Stützglied an dem mindestens einen Lagerteil festgelegt ist und an dem Kehrwalzenträger anliegt.If a plurality of support members are assigned to the at least one bearing part, provision can also be made for at least one first support member to be fixed to the broom carrier and to abut against the at least one bearing part and that at least one second support member is fixed to the at least one bearing part and rests against the broom carrier.

Zur kostengünstigen Herstellung der Kehrmaschine ist es von Vorteil, wenn das mindestens eine Stützglied mit dem mindestens einen Lagerteil einstückig verbunden ist.For cost-effective production of the sweeper, it is advantageous if the at least one support member is integrally connected to the at least one bearing part.

Wenn das mindestens eine Stützglied an dem Kehrwalzenträger festgelegt ist, so kann es mit diesem einstückig verbunden sein.If the at least one support member is fixed to the broom carrier, it may be integrally connected thereto.

Vorteilhafterweise hintergreift oder umgreift das mindestens eine Stützglied den Kehrwalzenträger. Dadurch kann beispielsweise erreicht werden, dass das mindestens eine Lagerteil relativ zum Kehrwalzenträger in axialer Richtung der Kehrwalze unbeweglich ist, also weder in einer axial von der Kehrwalze wegweisenden noch in einer axial zur Kehrwalze hinweisenden Richtung bewegt werden kann. Dieser Effekt kann zum Beispiel dann erzielt werden, wenn das mindestens eine Lagerteil am Kehrwalzenträger ebenso anliegt wie ein an ihm festgelegtes und den Kehrwalzenträger hintergreifendes Stützglied. Bei einer derartigen Ausführungsform ist die Position des mindestens einen Lagerteils relativ zum Kehrwalzenträger besonders gut definierbar.Advantageously, the at least one support member engages or surrounds the broom carrier. As a result, it can be achieved, for example, that the at least one bearing part is immovable relative to the broom carrier in the axial direction of the sweeping roller, that is, can not be moved either in a direction pointing axially away from the sweeping roller or in an direction pointing axially toward the sweeping roller. This effect can be achieved, for example, when the at least one bearing part rests against the broom carrier as well as a support member attached to it and behind the broom carrier. In such an embodiment, the position of the at least one bearing part relative to the broom carrier is particularly well defined.

Entsprechend den vorstehenden Ausführungen kann auch vorgesehen sein, dass das mindestens eine Stützglied das mindestens eine ihm zugeordnete Lagerteil hintergreift oder umgreift. Auch mit dieser Ausführungsform kann eine axiale Beweglichkeit des mindestens einen Lagerteils relativ zum Kehrwalzenträger verhindert werden.According to the above explanations, it can also be provided that the at least one support member engages behind or surrounds the at least one bearing part assigned to it. Also with this embodiment, an axial mobility of the at least one bearing part can be prevented relative to the broom carrier.

Bevorzugt ist das mindestens eine Lagerteil an einer der Kehrwalze abgewandten Seite des Kehrwalzenträgers angeordnet und weist der Kehrwalzenträger mindestens eine Durchgangsöffnung auf, die von der Kehrwalze oder von einer mit der Kehrwalze in Wirkverbindung stehenden Achswelle zur Lagerung an dem mindestens einen Lagerteil durchgriffen wird. Durch die Anordnung des mindestens einen Lagerteils an der der Kehrwalze abgewandten Seite des Kehrwalzenträgers ist das mindestens eine Lagerteil weitgehend von dem so genannten "Schmutzbereich" der Kehrwalze getrennt. Dadurch lässt sich die Verschmutzung des mindestens einen Lagerteiles gering halten. Um die Lagerung der Kehrwalze an dem mindestens einen Lagerteil zu ermöglichen, weist der Kehrwalzenträger mindestens eine Durchgangsöffnung auf, die von der Kehrwalze oder der Achswelle durchgriffen wird.Preferably, the at least one bearing part is arranged on one of the sweeping roller side facing away from the sweeping roller carrier and has the broom carrier at least one passage opening, which is penetrated by the sweeping roller or by a standing with the sweeping roller operatively connected axle for storage on the at least one bearing part. By arranging the at least one bearing part on the side facing away from the sweeping roller of the sweeping roller carrier, the at least one bearing part is largely separated from the so-called "dirt area" of the sweeping roller. As a result, the pollution of the at least one bearing part can be kept low. In order to enable the bearing of the sweeping roller on the at least one bearing part, the broom carrier has at least one passage opening, which is penetrated by the sweeping roller or the axle shaft.

Günstig ist es, wenn das mindestens eine Lagerteil eine Durchgangsöffnung des Kehrwalzenträgers zumindest teilweise abdeckt. Dadurch lässt sich die Menge an Schmutz, die aus dem Schmutzbereich durch die Durchgangsöffnung hindurch treten kann, gering halten.It is advantageous if the at least one bearing part at least partially covers a passage opening of the broom carrier. This allows the amount of dirt that can pass through the through hole from the dirt area, keep low.

Besonders vielseitig ist die Kehrmaschine einsetzbar, wenn die Lagerteile relativ zum Kehrwalzenträger eine Mehrzahl von Stellungen einnehmen können, in denen die Kehrwalze unterschiedliche Abstände zur Aufstellfläche aufweist.The sweeping machine can be used in a particularly versatile manner if the bearing parts can assume a plurality of positions relative to the broom carrier in which the sweeping roller has different distances from the mounting surface.

Bevorzugt sind die Lagerteile am Kehrwalzenträger beweglich gelagert. Dadurch ist es auf konstruktiv einfache Weise möglich, die Lagerteile am Kehrwalzenträger relativ zu einer Aufstellfläche der Kehrmaschine verstellbar auszubilden.Preferably, the bearing parts are movably mounted on the broom carrier. This makes it possible in a structurally simple manner, the bearing parts on Kehrwalzenträger relative to a footprint of the sweeper form adjustable.

Insbesondere ist es von Vorteil, wenn die Lagerteile am Kehrwalzenträger schwenkbar gelagert sind. Auf diese Weise kann die Verstellbarkeit der Lagerteile am Kehrwalzenträger auf technisch besonders einfache Weise umgesetzt werden.In particular, it is advantageous if the bearing parts are pivotally mounted on the broom carrier. In this way, the adjustability of the bearing parts on the broom carrier can be implemented in a technically particularly simple manner.

Die Lagerteile sind bevorzugt als zweiarmige Hebel ausgebildet und weisen jeweils erste Hebelarme auf, die von einem Benutzer zum Verstellen der Lagerteile ergreifbar sind, sowie zweite Hebelarme, an denen die Kehrwalze drehbar gehalten ist. Um ein Anheben und/oder Absenken der Kehrwalze relativ zur Aufstellfläche zu ermöglichen, können derart ausgestaltete Lagerteile schwenkbar an dem Kehrwalzenträger gelagert sein.The bearing parts are preferably designed as two-armed lever and each have first lever arms, which are engageable by a user for adjusting the bearing parts, and second lever arms, on which the sweeping roller is rotatably supported. In order to enable lifting and / or lowering of the sweeping roller relative to the footprint, such bearing parts configured can be pivotally mounted on the broom carrier.

Die Lagerteile sind auf kostengünstige Weise herstellbar, wenn sie als Flachmaterialien, insbesondere als Metallbleche, ausgebildet sind. Wie bereits erwähnt, kann das mindestens eine Stützglied mit dem ihm zugeordneten mindestens einen Lagerteil einstückig verbunden sein. Ist das Lagerteil als Flachmaterial ausgebildet, so kann das mindestens eine Stützglied zum Beispiel dadurch erzeugt werden, dass das Flachmaterial bereichsweise eingestanzt wird und das mindestens eine Stützglied in Form einer vom Flachmaterial weg gebogenen Lasche ausgestaltet wird.The bearing parts can be produced in a cost-effective manner, if they are designed as flat materials, in particular as metal sheets. As already mentioned, the at least one support member may be integrally connected to the at least one bearing part associated therewith. If the bearing part is designed as a flat material, the at least one support member can be produced, for example, by punching the flat material in regions and configuring the at least one support member in the form of a tab bent away from the flat material.

Vorteilhafterweise weist die Kehrmaschine mindestens ein an der Kehrwalze angeordnetes erstes Drehmomentübertragungsglied sowie mindestens ein mit einer Antriebsvorrichtung der Kehrmaschine in Wirkverbindung stehendes zweites Drehmomentübertragungsglied auf, die zum Antreiben der Kehrwalze zusammenwirken. Die Kehrmaschine kann beispielsweise eine Antriebsvorrichtung in Form eines Benzin- oder Elektromotors umfassen, der außer zum Antreiben der Kehrwalze auch zum Antreiben von Rädern der Kehrmaschine vorgesehen sein kann.Advantageously, the sweeper has at least one arranged on the sweeping roller first torque transmitting member and at least one with a drive device of the sweeper operatively connected second torque transmitting member, which cooperate to drive the sweeping roller. The sweeper may for example comprise a drive device in the form of a gasoline or electric motor, which may be provided except for driving the sweeping roller for driving wheels of the sweeper.

Günstig ist es, wenn das mindestens eine erste Drehmomentübertragungsglied und das mindestens eine zweite Drehmomentübertragungsglied zum Antreiben der Kehrwalze formschlüssig ineinander greifen. Dies gibt die Möglichkeit einer guten Drehmomentübertragung zwischen dem mindestens einen ersten und dem mindestens einen zweiten Drehmomentübertragungsglied. Bei den Drehmomentübertragungsgliedern kann es sich insbesondere um Mehrkante und dazu korrespondierende Aufnahme handeln, beispielsweise um Vierkant-, Sechskant- oder Torx-Systeme.It is advantageous if the at least one first torque-transmitting member and the at least one second torque-transmitting member engage in a positive engagement with one another for driving the sweeping roller. This gives the possibility of a good torque transmission between the at least one first and the at least one second torque transmitting member. The torque-transmitting members may in particular be multi-edge and corresponding receptacle, for example square, hexagonal or torx systems.

Bevorzugt sind das mindestens eine erste Drehmomentübertragungsglied und das mindestens eine zweite Drehmomentübertragungsglied entgegen der Federkraft des elastischen Elementes relativ zueinander verschieblich. Beispielsweise kann vorgesehen sein, dass das mindestens eine erste Drehmomentübertragungsglied und das mindestens eine zweite Drehmomentübertragungsglied voneinander weg verschieblich sind. Dies gibt die Möglichkeit, einen bestehenden Eingriff zwischen dem mindestens einen ersten und dem mindestens einen zweiten Drehmomentübertragungsglied aufzuheben, was zur Entnahme der Kehrwalze aus der Kehrmaschine erforderlich ist. Es kann auch vorgesehen sein, dass das mindestens eine erste und das mindestens eine zweite Drehmomentübertragungsglied entgegen der Federkraft aufeinander zu verschieblich sind. Ist das mindestens eine erste Drehmomentübertragungsglied an der Kehrwalze festgelegt, kann diese dann in Richtung des mindestens einen zweiten Drehmomentübertragungsgliedes verschoben werden. Dadurch kann es möglich sein, einen bestehenden Eingriff zwischen der Kehrwalze und einem der beiden Lagerteile zur Entnahme der Kehrwalze aus der Kehrmaschine aufzuheben.Preferably, the at least one first torque transmitting member and the at least one second torque transmitting member against the spring force of the elastic member relative to each other are displaceable. For example, it can be provided that the at least one first torque-transmitting member and the at least one second torque-transmitting member are displaceable away from one another. This makes it possible to cancel an existing engagement between the at least one first and the at least one second torque transmitting member, which is required for removal of the sweeping roller from the sweeper. It can also be provided that the at least one first and the at least one second torque transmitting member against the spring force are mutually displaceable. If the at least one first torque-transmitting member is fixed to the sweeping roller, it can then be displaced in the direction of the at least one second torque-transmitting member. This may make it possible to cancel an existing engagement between the sweeping roller and one of the two bearing parts for removal of the sweeping roller from the sweeper.

Vorteilhafterweise ist das elastische Element als zwischen dem mindestens einen ersten Drehmomentübertragungsglied und dem mindestens einen zweiten Drehmomentübertragungsglied angeordnete Druckfeder ausgebildet. Hierbei handelt es sich um eine konstruktiv einfache und kostengünstige Möglichkeit, das elastische Element auszubilden.Advantageously, the elastic element is formed as between the at least one first torque transmitting member and the at least one second torque transmitting member arranged compression spring. This is a structurally simple and inexpensive way to form the elastic element.

Von Vorteil ist es, wenn das mindestens eine erste Drehmomentübertragungsglied drehfest mit einer Welle der Kehrwalze verbunden ist und wenn das mindestens eine zweite Drehmomentübertragungsglied an einem der Lagerteile drehbar gelagert ist. Damit lässt sich eine konstruktiv einfache Ausgestaltung der Drehmomentübertragung erzielen. Das an dem Lagerteil drehbar gelagerte mindestens eine zweite Drehmomentübertragungsglied kann von der Antriebsvorrichtung der Kehrmaschine beispielsweise mittels eines Riementriebes angetrieben werden.It is advantageous if the at least one first torque transmitting member is rotatably connected to a shaft of the sweeping roller and when the at least one second torque transmitting member is rotatably mounted on one of the bearing parts. This makes it possible to achieve a structurally simple embodiment of the torque transmission. The rotatably mounted on the bearing part at least a second torque transmitting member can be driven by the drive device of the sweeper, for example by means of a belt drive.

Zur Übertragung des Drehmomentes auf das mindestens eine erste Drehmomentübertragungsglied greift das mindestens eine zweite Drehmomentübertragungsglied vorzugsweise in dieses ein. Wie bereits erwähnt, kann es mit diesem insbesondere formschlüssig in Eingriff stehen.For transmitting the torque to the at least one first torque transmitting member, the at least one second torque transmitting member preferably engages in this. As already mentioned, it can in particular be positively engaged with this.

Günstig ist es, wenn die Kehrwalze an einer ihrer den Lagerteilen zugewandten Seiten ein Drehlager mit einer Drehlagerabdeckung aufweist, mit der sie an einem der Lagerteile anliegt. Mittels der Drehlagerabdeckung kann sich die Kehrwalze an dem Lagerteil abstützen. Durch das Drehlager ist sie drehbeweglich gegenüber dem Lagerteil. Bei einem Austausch der Kehrwalze kann das Drehlager ebenfalls mit ausgetauscht und daher erneuert werden. Dies beugt der Gefahr von Lagerausfällen infolge einer Abnutzung des Drehlagers vor.It is advantageous if the sweeping roller on one of its sides facing the bearing parts has a pivot bearing with a pivot bearing cover, with which it bears against one of the bearing parts. By means of the pivot bearing cover, the sweeping roller can be supported on the bearing part. Through the pivot bearing it is rotatable relative to the bearing part. When replacing the sweeping roller, the pivot bearing can also be replaced with and therefore renewed. This prevents the risk of bearing failure due to wear of the pivot bearing.

Eine bevorzugte Ausführungsform einer erfindungemäßen Kehrmaschine ist in Figur 1 perspektivisch dargestellt und dort insgesamt mit dem Bezugszeichen 10 belegt. Die Kehrmaschine 10 ist als so genannte "Walk-behind-Kehrmaschine" ausgebildet, bei der der Benutzer die Kehrmaschine rückseitig steuert.A preferred embodiment of an inventive sweeper is in FIG. 1 shown in perspective and there occupied by the reference numeral 10. The sweeper 10 is designed as a so-called "walk-behind sweeper" in which the user controls the sweeper on the back.

Zur Fortbewegung umfasst die Kehrmaschine 10 zwei nahe ihrer Rückseite 12 angeordnete Laufräder 14 und 16 sowie eine an ihrer Vorderseite 18 angeordnete schwenkbare Lenkrolle 20. Die Lenkrolle 20 ist an einem Trägerteil 22 der Kehrmaschine 10 festgelegt, welches zur Aufnahme und Befestigung sämtlicher Bauteile der Kehrmaschine 10 vorgesehen ist und sich von deren Vorderseite 18 bis zu deren Rückseite 12 erstreckt. Die Laufräder 14 und 16 sind an einem Kehrwalzenträger 24 drehbar gelagert, der ebenfalls an dem Trägerteil 22 festgelegt ist.For locomotion, the sweeper 10 comprises two arranged near its rear side 12 wheels 14 and 16 and arranged at its front side 18 swivel castor 20. The castor 20 is fixed to a support member 22 of the sweeper 10, which for receiving and fixing all components of the sweeper 10th is provided and extends from the front 18 to the rear 12. The wheels 14 and 16 are rotatably mounted on a broom carrier 24, which is also fixed to the support member 22.

Das Trägerteil 22 bildet abschnittsweise eine Verkleidung der Kehrmaschine 10, und zwar eine linke Seitenverkleidung 26, eine rechte Seitenverkleidung 28 sowie eine Frontverkleidung 30, an bzw. auf die eine mit dem Trägerteil 22 lösbar verbindbare Haube 32 gesetzt ist.The carrier part 22 forms sections of a lining of the sweeper 10, namely a left side panel 26, a right side panel 28 and a front panel 30, to or on which a releasably connectable to the support member 22 hood 32 is set.

An der Rückseite 12 weist die Kehrmaschine 10 zwischen der linken Seitenverkleidung 26 und der rechten Seitenverkleidung 28 einen Kehrgutbehälter 34 auf, der eine rückwärtige Platte 36 umfasst, die eine Rückwand 38 der Kehrmaschine 10 bildet. Der Kehrgutbehälter 34 ist lösbar mit dem Trägerteil 22 verbindbar und kann zum Entleeren von der Kehrmaschine 10 entfernt werden.On the back 12, the sweeper 10 between the left side panel 26 and the right side panel 28 on a hopper 34 which includes a rear plate 36 which forms a rear wall 38 of the sweeper 10. The hopper 34 is detachably connectable to the support member 22 and can be removed for emptying of the sweeper 10.

Weiter ist an der Rückseite 12 oben an der linken Seitenverkleidung 26 eine Befestigungseinrichtung 40 für einen in der Zeichnung nicht dargestellten Handbügel der Kehrmaschine 10 angeordnet. Auch an der rechten Seitenverkleidung 28 ist eine in der Zeichnung nicht zu sehende Befestigungseinrichtung für den Handbügel angeordnet.Next, a fastening device 40 for a not shown in the drawing handrail of the sweeper 10 is disposed on the back 12 at the top of the left side panel 26. Also on the right side panel 28 a not visible in the drawing fastening means for the hand strap is arranged.

Mittels einer Kehrwalze 42, die am Kehrwalzenträger 24 auf untenstehend beschriebene Weise drehbeweglich gehalten ist, kann Schmutz von einer Aufstellfläche der Kehrmaschine 10 aufgekehrt werden. Die Kehrmaschine 10 arbeitet nach dem Überkopfkehrprinzip, d.h. die Kehrwalze 42 wirft den aufgekehrten Schmutz über sich hinweg in den Innenraum des Kehrgutbehälters 34.By means of a sweeping roller 42, which is rotatably held on the broom carrier 24 in the manner described below, dirt from a footprint of the sweeper 10 can be swept up. The sweeper 10 operates on the overhead sweeping principle, i. the sweeping roller 42 throws the swept dirt over it into the interior of the hopper 34.

Angetrieben wird die Kehrwalze 42 auf nachfolgend erläuterte Weise durch eine an sich bekannte und in der Zeichnung nicht gezeigte Antriebsvorrichtung, die unter der Haube 32 auf dem Trägerteil 22 befestigt ist. Die Antriebsvorrichtung kann beispielsweise als Benzin- oder Elektromotor ausgestaltet sein, wobei im Falle des Elektromotors zur Energiespeisung erforderliche Batterien ebenfalls an dem Trägerteil 22 befestigt sein können. Die Antriebsvorrichtung dient ferner zum Antreiben der Laufräder 14 und 16 sowie zum Antreiben eines bekannten und in der Zeichnung nicht gezeigten Saugaggregates zur Unterdruckbeaufschlagung des Innenraums des Kehrgutbehälters 34.The sweeping roller 42 is driven in the manner explained below by a known per se and not shown in the drawing drive device which is mounted under the hood 32 on the support member 22. The drive device may be configured, for example, as a gasoline or electric motor, wherein in the case of the electric motor required for energy supply batteries may also be attached to the support member 22. The drive device also serves for driving the wheels 14 and 16 and for driving a known and not shown in the drawing suction unit for negative pressure of the interior of the debris hopper 34th

Wie in Figur 2 und in den Figuren 4 bis 6 erkennbar ist, umfasst der Kehrwalzenträger 24 eine linke Seitenplatte 44 und eine rechte Seitenplatte 46, die jeweils einstückig aus Metallblechen gefertigt sind. An ihnen sind Lagerflansche 48 und 50 zur Lagerung der Laufräder 14 bzw. 16 befestigt.As in FIG. 2 and in the FIGS. 4 to 6 can be seen, the broom carrier 24 comprises a left side plate 44 and a right side plate 46, which are each made in one piece from metal sheets. On them bearing flanges 48 and 50 are mounted for supporting the wheels 14 and 16 respectively.

Die Seitenplatten 44 und 46 definieren zwischen sich einen so genannten "Schmutzbereich", in dem die Kehrwalze 42 angeordnet ist, wobei sie an zwei Lagerteilen 52 und 54 drehbeweglich gehalten ist. Die Lagerteile 52 und 54 sind der linken Seitenplatte 44 bzw. der rechten Seitenplatte 46 zugeordnet und jeweils auf den der Kehrwalze 42 abgewandten Seiten der Seitenplatten 44 und 46 angeordnet. Sie sind jeweils einstückig aus Metallblechen gefertigt. Bei der in der Zeichnung dargestellten Anordnung erinnert ihre Form ungefähr an die Form auf dem Kopf stehender Beile.The side plates 44 and 46 define therebetween a so-called "dirt area" in which the sweeping roller 42 is arranged, being rotatably supported on two bearing parts 52 and 54. The bearing members 52 and 54 are associated with the left side plate 44 and the right side plate 46 and respectively arranged on the side of the side plates 44 and 46 facing away from the sweeping roller 42. They are each made in one piece from metal sheets. In the arrangement shown in the drawing their shape is reminiscent of the shape upside down hatchet.

Die Lagerteile 52 und 54 sind an den der Vorderseite 18 der Kehrmaschine 10 zugewandten Enden 56 bzw. 58 der Seitenplatten 44 bzw. 46 um eine Schwenkachse 60, die parallel zu einer Aufstellfläche der Kehrmaschine 10 und zu einer Längsrichtung derselben orientiert ist, verschwenkbar an den Seitenplatten 44 bzw. 46 gelagert. Durch die schwenkbare Lagerung bilden die Lagerteile 52 und 54 zweiarmige Hebel mit Schenkelabschnitten 62 bzw. 64 - den Griffen des Beiles entsprechend - als ersten Hebelarmen sowie Plattenabschnitten 66 bzw. 68 - den Schneiden des Beiles entsprechend - als zweiten Hebelarmen. Auf die schwenkbare Lagerung der Lagerteile 52 und 54 wird nachfolgend noch eingegangen.The bearing parts 52 and 54 are at the front of the sweeper 18 10 facing ends 56 and 58 of the side plates 44 and 46 about a pivot axis 60 which is oriented parallel to a footprint of the sweeper 10 and to a longitudinal direction thereof, pivoted to the Side plates 44 and 46 stored. Due to the pivotable mounting the bearing parts 52 and 54 form two-armed lever with leg sections 62 and 64 - the handles of the hatchet - as the first lever arms and plate sections 66 and 68 - the cutting of the hatchet - as a second lever arms. The pivotable mounting of the bearing parts 52 and 54 will be discussed below.

Die Kehrwalze 42, die eine Hohlwelle 70 umfasst, von der Kehrborsten 72 abstehen, ist an den Lagerteilen 52 und 54, wie aus den Figuren 6 und 7 deutlich wird, folgendermaßen gehalten:

  • An ihrer, der linken Seitenplatte 44 zugewandten linken Seite 73 umfasst die Kehrwalze 42 ein Drehlager 74, das von einer napfartigen Lagerabdeckung 76 abgedeckt ist. Die Kehrwalze 42 durchgreift mit der Lagerabdeckung 76 eine Durchgangsöffnung 78 der linken Seitenplatte 44 und liegt mit der Lagerabdeckung 76 an dem Plattenabschnitt 66 des Lagerteils 52 an. Der Plattenabschnitt 66 umfasst eine Durchbrechung 80, in die die Lagerabdeckung 76 unverdrehbar zum Lagerteil 52 eintaucht (siehe auch Figur 3). Relativ zur Lagerabdeckung 76 ist die Hohlwelle 70 drehbeweglich, so dass die Kehrwalze 42 auch relativ zum Lagerteil 52 drehbeweglich ist.
The sweeping roller 42, which includes a hollow shaft 70, project from the sweeping bristles 72, is on the bearing members 52 and 54, as shown in FIGS FIGS. 6 and 7 becomes clear as follows:
  • At its, the left side plate 44 facing the left side 73, the sweeping roller 42 comprises a pivot bearing 74 which is covered by a cup-like bearing cover 76. The sweeping roller 42 engages with the bearing cover 76 has a through hole 78 of the left side plate 44 and abuts with the bearing cover 76 on the plate portion 66 of the bearing part 52. The plate portion 66 comprises an opening 80, in which the bearing cover 76 is non-rotatably immersed to the bearing part 52 (see also FIG. 3 ). Relative to the bearing cover 76, the hollow shaft 70 is rotatably movable, so that the sweeping roller 42 is also rotatable relative to the bearing part 52.

Das Lagerteil 52 deckt mit seinem Plattenabschnitt 66 die Durchgangsöffnung 78 in der Seitenplatte 44 zu einem Großteil ab. Damit wird weitgehend verhindert, dass von der Kehrwalze 42 aufgewirbelter Schmutz durch die Durchgangsöffnung 78 hindurch tritt und den Schmutzbereich verlässt.The bearing part 52 covers with its plate portion 66, the passage opening 78 in the side plate 44 from a large part. This largely prevents dirt raised by the sweeping roller 42 from passing through the passage opening 78 and leaving the dirt area.

An ihrer der rechten Seitenplatte 46 zugewandten rechten Seite 82 umfasst die Hohlwelle 70 ein erstes Drehmomentübertragungsglied 84. Dieses ist in Form einer hülsenförmigen Torxaufnahme 86 ausgebildet, die innerhalb der Hohlwelle 70 angeordnet und drehfest mit dieser verpresst ist.On its right side plate 46 facing the right side 82, the hollow shaft 70 comprises a first torque transmitting member 84. This is in the form of a sleeve-shaped Torxaufnahme 86 which is disposed within the hollow shaft 70 and rotatably pressed with this.

Das erste Drehmomentübertragungsglied 84 wirkt mit einem zweiten Drehmomentübertragungsglied 88 zum Antreiben der Kehrwalze 42 zusammen. Das zweite Drehmomentübertragungsglied 88 umfasst eine koaxial zur Hohlwelle 70 ausgerichtete Antriebswelle 90, auf der drehfest ein Torxaufsatz 92 aufgepresst ist, welcher in die Torxaufnahme 86 eingreift und formschlüssig mit dieser in Eingriff steht.The first torque transmitting member 84 cooperates with a second torque transmitting member 88 for driving the sweeping roller 42. The second torque-transmitting member 88 includes a coaxial with the hollow shaft 70 aligned drive shaft 90, on the rotationally fixed Torxaufsatz 92nd is pressed, which engages in the Torxaufnahme 86 and positively engages with this.

Die Antriebswelle 90 ist mittels eines Lagerflansches 94, der am Plattenabschnitt 68 des Lagerteils 54 befestigt ist, drehbar am Lagerteil 54 gelagert. Die Antriebswelle 90 durchgreift eine Durchgangsöffnung 96 der rechten Seitenplatte 46, die vom Lagerteil 54 mit seinem Plattenabschnitt 68 zum Großteil abgedeckt wird. Dadurch lässt sich weitgehend vermeiden, dass Schmutz den Schmutzbereich verlässt, indem er durch die Durchgangsöffnung 96 hindurch tritt.The drive shaft 90 is rotatably mounted on the bearing part 54 by means of a bearing flange 94 which is fixed to the plate portion 68 of the bearing part 54. The drive shaft 90 passes through a through opening 96 of the right side plate 46, which is covered by the bearing part 54 with its plate portion 68 for the most part. This largely prevents dirt from leaving the dirt area by passing through the passage opening 96.

Wie insbesondere in der Explosionsdarstellung der Figur 7 zu sehen ist, ist zwischen der Torxaufnahme 86 und dem Torxaufsatz 92 ein elastisches Element 98 in Form einer Druckfeder 100 angeordnet, das die Torxaufnahme 86 und den Torxaufsatz 92 und damit die Hohlwelle 70 und die Antriebswelle 90 in axialer Richtung der Kehrwalze 42 mit einer Federkraft beaufschlagt. In Folge dieser Federkraft werden die Lagerteile 52 und 54 an ihren Plattenabschnitten 66 bzw. 68 jeweils mit einer axialen von der Kehrwalze 42 wegweisenden Federkraft beaufschlagt. Dies führt dazu, dass die Kehrwalze 42 zwischen den Lagerteilen 52 und 54 durch die Wirkung der Druckfeder 100 eingespannt ist.As in particular in the exploded view of FIG. 7 can be seen, is disposed between the Torxaufnahme 86 and the Torx essay 92, an elastic member 98 in the form of a compression spring 100, the Torxaufnahme 86 and the Torxaufsatz 92 and thus the hollow shaft 70 and the drive shaft 90 in the axial direction of the sweeping roller 42 with a spring force applied. As a result of this spring force, the bearing parts 52 and 54 are acted upon at their plate portions 66 and 68 respectively with an axial direction away from the sweeping roller 42 spring force. This results in that the sweeping roller 42 is clamped between the bearing parts 52 and 54 by the action of the compression spring 100.

Zum Antreiben der Kehrwalze 42 ist auf der der Kehrwalze 42 abgewandten Seite der Antriebswelle 90 drehfest eine Riemenscheibe 102 aufgesetzt, die auf an sich bekannte und deswegen in der Zeichnung nicht dargestellte Weise durch einen Riementrieb mit der bereits erwähnten Antriebsvorrichtung in Wirkverbindung steht. Durch die mittels eines Antriebsriemens auf die Riemenscheibe 102 übertragene Drehbewegung ist es möglich, die Antriebswelle 90 und die Kehrwalze 42 zur Rotation um ihre gemeinsame Drehachse 104 anzutreiben.To drive the sweeping roller 42 is rotatably on the sweeping roller 42 side facing away from the drive shaft 90, a pulley 102 placed on a known per se and therefore not shown in the drawing by a belt drive with the already mentioned drive device in Active compound is. By virtue of the rotational movement transmitted to the pulley 102 by means of a drive belt, it is possible to drive the drive shaft 90 and the sweeping roller 42 for rotation about their common axis of rotation 104.

Um zu vermeiden, dass die Lagerteile 52 und 54 aufgrund der Federkraft der Druckfeder 100, mit der sie über die Kehrwalze 42 bzw. die Antriebswelle 90 beaufschlagt werden, jeweils so weit in von der Kehrwalze 42 wegweisende Richtungen gedrückt werden, dass sie die Kehrwalze 42 unerwünscht freigeben, stützen sich die Lagerteile 52 und 54 an den Seitenplatten 44 bzw. 46 des Kehrwalzenträgers 24 ab. Hierzu umfassen die Lagerteile 52 und 54, wie in den Figuren 2 bis 5 erkennbar ist, Stützglieder 106 bzw. 108. Diese sind mit den als Metallblechen ausgebildeten Lagerteilen 52 und 54 einstückig verbunden und werden durch Einstanzen der Lagerteile 52 und 54 und anschließendes Umbiegen der eingestanzten Bereiche gefertigt. Die Stützglieder 106 und 108 bilden auf diese Weise von den Lagerteilen 52 und 54 abstehende Laschen 110 bzw. 112.In order to avoid that the bearing parts 52 and 54 are pressed so far in the direction away from the broom 42 directions due to the spring force of the compression spring 100, with which they are acted upon by the sweeping roller 42 and the drive shaft 90, that they the sweeping roller 42nd release undesirable, the bearing parts 52 and 54 are based on the side plates 44 and 46 of the broom carrier 24 from. For this purpose, the bearing parts 52 and 54, as in the FIGS. 2 to 5 can be seen, support members 106 and 108. These are integrally connected to the formed as metal sheets bearing parts 52 and 54 and are made by punching the bearing parts 52 and 54 and then bending the stamped areas. The support members 106 and 108 form in this way from the bearing members 52 and 54 projecting tabs 110 and 112, respectively.

Die Laschen 110 und 112 hintergreifen die Seitenplatten 44 bzw. 46 und liegen an den der Kehrwalze 42 zugewandten Seiten der Seitenplatten 44 und 46 an. Dadurch wird die die Lagerteile 52 und 54 beaufschlagende Federkraft der Druckfeder 100 effektiv an die Seitenplatten 44 und 46 des Kehrwalzenträgers 24 abgeleitet, so dass die Lagerteile 52 und 54 nicht in voneinander wegweisende Richtungen auseinandergedrückt werden. Damit kann ein unerwünschtes Freigeben der Kehrwalze 42 vermieden werden.The tabs 110 and 112 engage behind the side plates 44 and 46 and abut against the sweeping roller 42 facing sides of the side plates 44 and 46 at. Thereby, the spring force of the compression spring 100 acting on the bearing parts 52 and 54 is effectively dissipated to the side plates 44 and 46 of the broom carrier 24, so that the bearing parts 52 and 54 are not forced apart in directions facing away from each other. Thus, an undesirable release of the sweeping roller 42 can be avoided.

Alternativ oder ergänzend zu den Stützgliedern 106 und 108 kann die Kehrmaschine 10 Stützglieder aufweisen, die an den Seitenplatten 44 und 46 festgelegt sind, die Lagerteile 52 und 54 hintergreifen und an diesen anliegen. Die die Lagerteile 52 und 54 beaufschlagende Federkraft kann auf diese Weise ebenfalls an die Seitenplatten 44 bzw. 46 abgeleitet werden.Alternatively or in addition to the support members 106 and 108, the sweeper 10 may comprise support members which are fixed to the side plates 44 and 46, the bearing members 52 and 54 engage behind and abut against these. The spring forces acting on the bearing parts 52 and 54 can also be dissipated to the side plates 44 and 46 in this way.

Zwischen den Laschen 110 und 112 und den Plattenabschnitten 66 bzw. 68 ist jeweils ein spaltförmiger Zwischenraum 114 bzw. 116 definiert, in denen die Seitenplatten 44 bzw. 46 mit Rändern 118 bzw. 120 der Durchgangsöffnungen 78 bzw. 96 eingreifen (Figuren 3 bis 5). Dadurch sind die Lagerteile 52 und 54 in axialer Richtung der Kehrwalze 42 unbeweglich gegenüber den Seitenplatten 44 bzw. 46 und auch der Kehrwalze 42. Diese ist somit zuverlässig an den Lagerteilen 52 und 54 und mittels dieser auch an dem Kehrwalzenträger 24 gehalten.Between the tabs 110 and 112 and the plate portions 66 and 68, respectively, a gap-shaped gap 114 and 116 is defined, in which the side plates 44 and 46 with edges 118 and 120 of the through holes 78 and 96 engage ( FIGS. 3 to 5 ). Thus, the bearing members 52 and 54 are immovable in the axial direction of the sweeping roller 42 relative to the side plates 44 and 46 and also the sweeping roller 42. This is thus reliably on the bearing parts 52 and 54 and held by this also on the broom carrier 24.

Wie bereits erwähnt, sind die Lagerteile 52 und 54 an den Seitenplatten 44 bzw. 46 um die Schwenkachse 60 schwenkbar gelagert. Dies erlaubt es einem Benutzer, den Abstand der Kehrwalze 42 von einer Aufstellfläche der Kehrmaschine 10 zu verändern. Hierzu sind die Schenkelabschnitte 62 und 64 der Lagerteile 52 bzw. 54 an ihren Enden mit Handgriffen 122 bzw. 124 versehen, an denen der Benutzer nach Öffnen der Haube 32 der Kehrmaschine 10 angreifen kann. Er kann die Schenkelabschnitte 62 und 64 mittels der Handgriffe 122 bzw. 124 mit von der Kehrwalze 42 wegweisenden Kräften beaufschlagen, so dass Stifte 126 und 128, die nahe den Handgriffen 122 bzw. 124 an den Schenkelabschnitten 62 bzw. 64 angeordnet sind, mit einer von einer Mehrzahl von Bohrungen 130 bzw. 132, welche an den Seitenplatten 44 bzw. 46 angeordnet sind, außer Eingriff geraten. Die Stifte 126, 128 können an die Schenkelabschnitte 62 bzw. 64 beispielsweise angeformt, angeschraubt oder angeschweißt sein.As already mentioned, the bearing parts 52 and 54 are pivotally mounted on the side plates 44 and 46 about the pivot axis 60. This allows a user to change the distance of the sweeping roller 42 from a footprint of the sweeper 10. For this purpose, the leg portions 62 and 64 of the bearing parts 52 and 54 are provided at their ends with handles 122 and 124, in which the user after opening the hood 32 of the sweeper 10 can attack. It can act on the leg portions 62 and 64 by means of the handles 122 and 124 with wegweisenden of the sweeping roller 42 forces, so that pins 126 and 128, which are arranged near the handles 122 and 124 at the leg portions 62 and 64, with a from a plurality of bores 130 and 132, respectively, which are arranged on the side plates 44 and 46, respectively are disengaged. The pins 126, 128 may be formed, screwed or welded to the leg portions 62 and 64, for example.

Das Eingreifen der Stifte 126 und 128 in eine der Mehrzahl von Bohrungen 130 bzw. 132 kann durch Verschwenken der Lagerteile 52 bzw. 54 um die Schwenkachse 60 erreicht werden und entspricht Stellungen der Kehrwalze 42, in der diese jeweils einen unterschiedlichen Abstand von der Aufstellfläche der Kehrmaschine 10 aufweist. Bei der vorliegend gezeigten Ausführungsform weisen die Seitenplatten 44 und 46 jeweils zehn Bohrungen 130 bzw. 132 auf, so dass die Kehrwalze 42 zehnerlei verschiedene Abstände von der Aufstellfläche einnehmen kann.The engagement of the pins 126 and 128 in one of the plurality of holes 130 and 132 can be achieved by pivoting the bearing members 52 and 54 about the pivot axis 60 and corresponds to positions of the sweeping roller 42, in which these each a different distance from the footprint of the Sweeper 10 has. In the embodiment shown here, the side plates 44 and 46 each have ten holes 130 and 132, so that the sweeping roller 42 can take tens of different distances from the footprint.

Ein derartiges Anheben oder Absenken der Kehrwalze 42 ist beispielsweise bei Verschleiß der Kehrwalze 42 erforderlich. Es kann auch vorgesehen sein, dass mit der Kehrmaschine 10 unterschiedliche Kehrwalzen, die etwa zum Reinigen unterschiedlicher Aufstellflächen erforderlich sind, zum Einsatz kommen, deren Abstand zur Aufstellfläche jeweils anzupassen ist.Such raising or lowering of the sweeping roller 42 is required, for example, when the sweeping roller 42 is worn. It can also be provided that with the sweeper 10 different sweeping rollers, which are required for cleaning different installation surfaces, are used, the distance to the footprint is in each case adapted.

Durch den bereits angesprochenen Eingriff der Ränder 118 und 120 der Durchgangsöffnungen 78 bzw. 96 in die Zwischenräume 114 bzw. 116 definieren diese zugleich Führungen für die Lagerteile 52 bzw. 54 beim Verschwenken.By the already mentioned engagement of the edges 118 and 120 of the through holes 78 and 96 in the intermediate spaces 114 and 116, these define at the same time guides for the bearing parts 52 and 54 during pivoting.

Wie anhand von Figur 6 erkennbar ist, ist ein Wechsel der Kehrwalze 42 folgendermaßen werkzeuglos durchführbar:

  • Die Kehrwalze 42 ist mit einer axialen Kraft in Richtung des Lagerteils 54 entgegen der Federkraft der Druckfeder 100 zu beaufschlagen, so dass diese zusammengedrückt wird. Das Lagerteil 54 stützt sich dabei mittels des Stützgliedes 108 an der Seitenplatte 46 ab. Durch die Kraftbeaufschlagung der Kehrwalze 42 ist es möglich, dass die Lagerabdeckung 76 außer Eingriff mit dem Lagerteil 52 gerät. Die Kehrwalze 52 kann daraufhin mit der linken Seite 73 führend zwischen den Lagerteilen 52 und 54 herausgezogen werden, bis sie außer Eingriff mit dem zweiten Drehmomentübertragungsglied 88 gerät. Zum Einbau der Kehrwalze 42 ist in umgekehrter Reihenfolge vorzugehen.
As based on FIG. 6 can be seen, a change of the sweeping roller 42 is carried out without tools as follows:
  • The sweeping roller 42 is to be acted upon with an axial force in the direction of the bearing part 54 against the spring force of the compression spring 100, so that it is compressed. The bearing part 54 is supported by means of the support member 108 on the side plate 46 from. By the application of force to the sweeping roller 42, it is possible for the bearing cover 76 to disengage from the bearing part 52. The sweeping roller 52 can then be pulled out with the left side 73 leading between the bearing parts 52 and 54 until it disengages from the second torque transmitting member 88. To install the sweeping roller 42, proceed in the reverse order.

Das in die Kehrwalze 42 integrierte Drehlager 74 wird beim Wechsel der Kehrwalze 42 ebenfalls mit ausgetauscht. Dies reduziert die Gefahr von Ausfällen des Drehlagers 74, welches zusammen mit der Kehrwalze 42 erneuert wird.The integral with the sweeping roller 42 pivot bearing 74 is also replaced when changing the sweeping roller 42. This reduces the risk of failure of the pivot bearing 74, which is renewed together with the sweeping roller 42.
