Description

Die Erfindung betrifft ein Fahrwerk für ein Schienenfahrzeug, mit zumindest einem innengelagerten ersten Radsatz mit einer ersten Radsatzwelle, einem ersten Rad und einem zweiten Rad.The invention relates to a running gear for a rail vehicle, having at least one internally mounted first wheel set with a first wheel set axle, a first wheel and a second wheel.

Sensoren von Zugsicherungssystemen wie Antennen oder Auslösehebel für Fahrsperren müssen gemäß ihrer Spezifikation in Fahrtrichtung eines Schienenfahrzeuges möglichst weit vorne und in vertikaler Richtung nahe über einer Schienenoberkante angebracht werden. Bei Schienenfahrzeugen mit außengelagerten Fahrwerken können Zugsicherungssensoren auf einem Langträger eines Fahrwerksrahmens angeordnet werden. Bei innengelagerten Fahrwerken ist das häufig nur schwer möglich, da nach dem Prinzip der Innenlagerung der Langträger des Fahrwerksrahmens innerhalb von Räderpaaren verläuft und außenliegende Räder eine unmittelbare Anbindung von Zugsicherungssensoren an einer Vorderseite des Fahrwerks verhindern.According to their specification, sensors of train protection systems such as antennas or release levers for travel locks must be attached as far forward as possible in the direction of travel of a rail vehicle and in the vertical direction close to the top edge of the rail. In the case of rail vehicles with externally mounted bogies, train protection sensors can be arranged on a longitudinal beam of a bogie frame. In the case of internally mounted bogies, this is often only possible with difficulty since, according to the principle of internal mounting, the longitudinal member of the bogie frame runs within pairs of wheels and external wheels prevent train protection sensors from being directly connected to a front side of the bogie.

Ferner ist aus denselben Gründen eine Anbindung von Stromabnehmern sowie weiterer Komponenten, in deren Auslegung vertikale Bewegungen gegenüber einer Schienenoberkante berücksichtigt werden müssen, nur schwer möglich.Furthermore, for the same reasons, it is difficult to connect pantographs and other components whose design must take into account vertical movements relative to the upper edge of the rail.

Zudem ist auch eine Anordnung von Trittleitern, Bremszangen, Sensoren und Erdungskontakten an Fahrwerksaußenseiten bei innengelagerten Fahrwerken schwierig.In addition, an arrangement of stepladders, brake calipers, sensors and grounding contacts on the outside of the undercarriage is difficult for undercarriages with internal bearings.

Aus dem Stand der Technik ist z.B. das innengelagerte Siemens-Fahrwerk SF7000 bekannt.For example, the Siemens SF7000 bogie with internal bearings is known from the prior art.

Der genannte Ansatz weist in seiner bekannten Form den Nachteil auf, dass Zugsicherungssensoren, Stromabnehmer etc. aufgrund der Innenlagerung und aufgrund des Fehlens von entsprechenden Vorrichtungen im Bereich der Räder nicht in der Nähe einer Schienenoberkante angeordnet werden können.In its known form, the stated approach has the disadvantage that train protection sensors, pantographs, etc. cannot be arranged near a rail top edge due to the internal storage and due to the lack of corresponding devices in the area of the wheels.

Weiterhin ist die DE 33 09 969 A1 bekannt, welche ein Spannelement für eine Welle-Nabe-Verbindung zeigt. Das Spannelement ist als kegelförmiger Zylinderspannring in einem federelastischen Material ausgeführt. Der Zylinderspannring weist Ausnehmungen auf, welche eine Formänderung des Spannelements unter Belastung erleichtern. Weiterhin sind konische Ringelemente vorgesehen, welche unter Belastung gegeneinander schwenkbar sind.Furthermore, the DE 33 09 969 A1 known, which shows a clamping element for a shaft-hub connection. The clamping element is designed as a conical cylindrical clamping ring made of a resilient material. The cylindrical clamping ring has recesses which facilitate a change in shape of the clamping element under load. Furthermore, conical ring elements are provided, which can be pivoted against each other under load.

Ferner zeigt die US 2 636 451 A ein innengelagertes Fahrwerk für ein Schienenfahrzeug mit Scheibenbremsen, welche an Radaußenseiten angeordnet sind.Furthermore, the U.S. 2,636,451 A an internally mounted chassis for a rail vehicle with disc brakes, which are arranged on the outside of the wheel.

Die DE 198 26 448 A1 offenbart ein Fahrwerk mit Innenlagerung, bei welchem verschiedene Komponenten an Radaußenseiten vorgesehen sind.The DE 198 26 448 A1 discloses a chassis with inner bearings in which various components are provided on wheel outer sides.

In der FR 2 383 810 A1 ist ein Spurwechselfahrwerk beschrieben. Es ist eine Stützvorrichtung vorgesehen, welche über Schrauben mit einem Fahrwerksrahmen verbunden ist.In the FR 2 383 810 A1 a lane change chassis is described. A support device is provided, which is connected to a chassis frame via screws.

Die DE 533 784 C zeigt ein Deichselfahrwerk, bei welchem je ein Deichselarm über eine Buchsen-Bolzen-Verbindung mit einem Radsatzwellenende verbunden ist.The DE 533 784 C shows a drawbar chassis in which each drawbar arm is connected to a wheelset shaft end via a socket-bolt connection.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik weiterentwickeltes Fahrwerk anzugeben.The invention is therefore based on the object of specifying a chassis that is further developed than the prior art.

Erfindungsgemäß wird diese Aufgabe mit einem Fahrwerk nach Anspruch 1 gelöst.According to the invention, this object is achieved with a chassis according to claim 1.

Dadurch können Komponenten wie Stromabnehmer oder Zugsicherungssensoren etc. in der Nähe einer Bahninfrastruktur angeordnet werden es wird somit eine Interaktion dieser Schnittstellenkomponenten mit in Außenbereichen von Gleisen, beispielsweise in einem Gleiskörper vorgesehenen Zugsicherungseinrichtungen erleichtert.As a result, components such as pantographs or train protection sensors etc. can be arranged in the vicinity of a railway infrastructure, thus facilitating interaction of these interface components with train protection devices provided in the outer regions of tracks, for example in a track body.

Weiterhin können auf der Tragevorrichtung auch Trittleitern bzw. Trittstufen, Bremszangen, Sensoren und Erdungskontakte etc. angeordnet werden, wodurch bei dem Fahrwerk mit innengelagertem ersten Radsatz eine von außengelagerten Fahrwerken bekannte Flexibilität im Hinblick auf eine Anordnung von Komponenten auf Fahrwerksaußenseiten bewirkt wird.Furthermore, stepladders or steps, brake calipers, sensors and grounding contacts etc. can also be arranged on the carrying device, whereby the chassis with internally mounted first wheel set has the flexibility known from externally mounted chassis with regard to an arrangement of components on the chassis outer sides.

Ferner wird aufgrund der ersten Spannanordnung eine günstige Kraftübertragung von der Tragevorrichtung über die erste Spannanordnung auf den ersten Radsatz erzielt. Von einem Gleis beispielsweise aufgrund von Gleislagefehlern ungefedert auf das erste Rad und das zweite Rad übertragene Stöße bzw. Kräfte und Momente können zu einem großen Teil bzw. vollständig mittels der ersten Spannanordnung übertragen werden. Ein Einsatz von Schraubenverbindungen zwischen der ersten Spannanordnung und dem Radsatz kann reduziert werden bzw. es kann völlig darauf verzichtet werden.Furthermore, because of the first tensioning arrangement, a favorable transmission of force from the carrying device via the first tensioning arrangement to the first wheel set is achieved. Impacts or forces and moments transmitted unsprung from a track, for example due to track geometry errors, to the first wheel and the second wheel can be transmitted to a large extent or completely by means of the first clamping arrangement. The use of screw connections between the first clamping arrangement and the wheelset can be reduced or it can be dispensed with entirely.

Schrauben sind lediglich als Redundanz erforderlich. Darüber hinaus wird eine vorteilhafte Flexibilität in Bezug auf Wartung, Instandhaltung und Nachrüstung der ersten Spannanordnung erzielt, da diese einfach zu montieren und zu demontieren ist.Screws are only required for redundancy. In addition, an advantageous flexibility in terms of maintenance, servicing and retrofitting is the first Clamping arrangement achieved because it is easy to assemble and disassemble.

Durch diese Maßnahme wird weiterhin eine einfache und rasche Montierbarkeit und Demontierbarkeit der ersten Spannanordnung bewirkt. Beispielsweise ist es für einen Spannvorgang der ersten Spannanordnung lediglich erforderlich, die Zentralschraube anzuziehen bzw. zu lösen.This measure also ensures that the first clamping arrangement can be assembled and disassembled easily and quickly. For example, it is only necessary for a clamping process of the first clamping arrangement to tighten or loosen the central screw.

Es ist günstig, wenn die zumindest erste Spannanordnung zumindest teilweise von einem ersten Hohlwellensegment der ersten Radsatzwelle ummantelt ist.It is favorable if the at least first clamping arrangement is at least partially encased by a first hollow shaft segment of the first wheelset shaft.

Durch diese Maßnahme ergibt sich eine kompakte, platzsparende Ausführung der ersten Spannanordnung. Weiterhin ist die erste Spannanordnung dadurch zumindest teilweise vor Umgebungseinflüssen geschützt.This measure results in a compact, space-saving design of the first clamping arrangement. Furthermore, the first clamping arrangement is thereby at least partially protected from environmental influences.

Im Zusammenhang mit dem Spannvorgang der ersten Spannanordnung ist es weiterhin günstig, wenn das Gegenstück mittels zumindest eines ersten Führungszapfens in dem Spannstück positioniert ist.In connection with the clamping process of the first clamping arrangement, it is also favorable if the counterpart is positioned in the clamping piece by means of at least one first guide pin.

Durch diese Maßnahme werden unbeabsichtigte Bewegungen des Gegenstücks relativ zu dem Spannstück vermieden.This measure prevents unintentional movements of the counterpart relative to the clamping piece.

Eine günstige Lösung wird erzielt, wenn das Spannstück einen konischen Innenraum aufweist.A favorable solution is achieved when the clamping piece has a conical interior.

In diesem Zusammenhang ist es weiterhin günstig, wenn das Gegenstück eine konische Mantelfläche aufweist.In this context, it is also favorable if the counterpart has a conical lateral surface.

Durch diese Maßnahme wird über eine Keilwirkung eine günstige Übertragung von Kräften von der Zentralschraube auf das Spannstück und somit eine Vorspannung des Spannstücks bzw. eine Radialkraft zwischen der ersten Spannanordnung und dem ersten Radsatz bewirkt.This measure causes a favorable transmission of forces from the central screw to the clamping piece and thus a prestressing of the clamping piece or a radial force between the first clamping arrangement and the first wheel set via a wedge effect.

Es ist günstig, wenn das Spannstück zumindest teilweise, insbesondere an seinem Auslauf, ballig ausgebildet ist. Durch diese Maßnahme wird einerseits der Vorteil eines Toleranzausgleichs bei einem Einführen des Spannstücks in das erste Hohlwellensegment bzw. bei einem Verspannen des Spannstücks mit der ersten Radsatzwelle erzielt und andererseits eine kantige Auflage des Spannstücks an einer Oberfläche der ersten Radsatzwelle vermieden.It is favorable if the clamping piece is at least partially crowned, in particular at its outlet. This measure on the one hand has the advantage of tolerance compensation when the clamping piece is inserted into the first hollow shaft segment or when the Achieved clamping piece with the first wheelset shaft and on the other hand avoided an edged support of the clamping piece on a surface of the first wheelset shaft.

Eine vorteilhafte Ausgestaltung erhält man, wenn das Spannstück zumindest einen ersten Längsschlitz aufweist. Durch diese Maßnahme wird unter Belastung der ersten Spannanordnung eine Formänderung des Spannstücks erleichtert. Es wird eine genaue Passung zwischen dem Spannstück und dem ersten Radsatz bewirkt.An advantageous embodiment is obtained when the clamping piece has at least one first longitudinal slot. This measure facilitates a change in shape of the clamping piece when the first clamping arrangement is loaded. An exact fit is effected between the clamping piece and the first wheel set.

Weiterhin ist es günstig, wenn der zumindest erste Führungszapfen in dem zumindest ersten Längsschlitz geführt ist.Furthermore, it is favorable if the at least first guide pin is guided in the at least first longitudinal slot.

Durch diese Maßnahme kann auf eigene Ausnehmungen, Nuten etc. für den Führungszapfen verzichtet und das Spannstück konstruktiv und fertigungstechnisch einfach ausgeführt werden.As a result of this measure, separate recesses, grooves, etc. for the guide pin can be dispensed with and the clamping piece can be designed in a simple manner in terms of construction and production technology.

Es ist günstig, wenn dass die Tragevorrichtung ein Schauloch aufweist.It is favorable if the carrying device has an inspection hole.

Durch diese Maßnahme kann die erste Spannanordnung von außen mittels Sichtkontrolle einfach überprüft werden. Beispielsweise können dadurch Kennzeichnungen auf der Zentralschraube bezüglich deren Montagezustands kontrolliert werden. Es ist für die Sichtkontrolle aufgrund des Schaulochs keine Demontage der Tragevorrichtung erforderlich.As a result of this measure, the first clamping arrangement can be easily checked from the outside by means of a visual inspection. For example, markings on the central screw can be checked with regard to their assembly status. It is not necessary to dismantle the carrying device for the visual inspection due to the inspection hole.

Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.The invention is explained in more detail below using exemplary embodiments.

Fig. 1 zeigt einen Schrägriss einer beispielhaften Ausführung einer erfindungsgemäßen ersten Spannanordnung 7 in geschnittener Darstellung. Die erste Spannanordnung 7 weist ein Spannstück 11, ein Gegenstück 13 und eine Zentralschraube 12 auf und ist teilweise in einem ersten Hohlwellensegment 10 einer ersten Radsatzwelle 3 angeordnet, d.h. ist teilweise von dem ersten Hohlwellensegment 10 ummantelt. 1 shows an oblique view of an exemplary embodiment of a first clamping arrangement 7 according to the invention in a sectional representation. The first clamping arrangement 7 has a clamping piece 11 , a counterpart 13 and a central screw 12 and is partially arranged in a first hollow shaft segment 10 of a first wheelset shaft 3 , ie it is partially encased by the first hollow shaft segment 10 .

Dabei handelt es sich um eine günstige Lösung.This is a cheap solution.

Erfindungsgemäß wäre es auch denkbar, die erste Spannanordnung 7 beispielsweise mit einem Wellenstummel eines ersten Rads 5 zu verbinden.According to the invention, it would also be conceivable to connect the first clamping arrangement 7 to a stub shaft of a first wheel 5, for example.

Die erste Radsatzwelle 3 sowie das erste Rad 5 und ein nicht gezeigtes zweites Rad bilden einen innengelagerten ersten Radsatz 1 eines Fahrwerks eines Schienenfahrzeugs.The first wheel set shaft 3 and the first wheel 5 and a second wheel (not shown) form an internally mounted first wheel set 1 of a running gear of a rail vehicle.

Das Spannstück 11 weist einen flanschartigen Bereich auf, in dem es mittels einer ersten Sechskantschraube 25 und einer zweiten Sechskantschraube 26 stirnseitig mit der ersten Radsatzwelle 3 kraftschlüssig verbunden ist. Die erste Sechskantschraube 25 und die zweite Sechskantschraube 26 sind als Redundanz angeordnet. Ein überwiegender Teil von in das Spannstück 11 eingeleiteten Kräften und Momenten (z.B. Torsionsmomente und Biegemomente) wird über einen Presssitz zwischen dem Spannstück 11 und dem ersten Hohlwellensegment 10 übertragen.The clamping piece 11 has a flange-like area in which it is non-positively connected to the first wheelset axle 3 by means of a first hexagonal screw 25 and a second hexagonal screw 26 . The first hexagonal screw 25 and the second hexagonal screw 26 are arranged as a redundancy. A predominant part of the forces and moments (e.g. torsional moments and bending moments) introduced into the clamping piece 11 is transmitted via a press fit between the clamping piece 11 and the first hollow shaft segment 10 .

Im Bereich eines konischen Innenraums 16 des Spannstücks 11 ist das Gegenstück 13, das eine konische Mantelfläche 18 aufweist, über einen ersten Führungszapfen 14, der in einem ersten Längsschlitz 19 des Spannstücks 11 geführt ist und einen zweiten Führungszapfen 15, der in einem zweiten Längsschlitz 20 des Spannstücks 11 angeordnet ist, in dem Spannstück 11 positioniert. Weiterhin sind auf dem Spannstück 11 ein dritter Längsschlitz 21, ein vierter Längsschlitz 22 sowie, nicht dargestellt, weitere Längsschlitze vorgesehen, in denen ein dritter Führungszapfen, ein vierter Führungszapfen sowie, ebenfalls nicht gezeigt, weitere Führungszapfen geführt sind.In the area of a conical interior 16 of the clamping piece 11, the counterpart 13, which has a conical lateral surface 18, is guided by a first guide pin 14, which is guided in a first longitudinal slot 19 in the clamping piece 11, and a second guide pin 15, which is guided in a second longitudinal slot 20 of the clamping piece 11 is positioned in the clamping piece 11 . Furthermore, a third longitudinal slot 21, a fourth longitudinal slot 22 and, not shown, further longitudinal slots are provided on the clamping piece 11, in which a third guide pin, a fourth Guide pins and, also not shown, other guide pins are performed.

Der erste Längsschlitz 19, der zweite Längsschlitz 20, der dritte Längsschlitz 21, der vierte Längsschlitz 22 sowie die weiteren Längsschlitze sind jeweils an einem Ende halbzylindrisch abgesetzt, d.h. nicht durchgängig ausgeführt. Das Gegenstück 13 wird mittels des ersten Führungszapfens 14, des zweiten Führungszapfens 15 und der weiteren Führungszapfen sowie des ersten Längsschlitzes 19, des zweiten Längsschlitzes 20, des dritten Längsschlitzes 21, des vierten Längsschlitzes 22 sowie der weiteren Längsschlitze in das Spannstück 11 eingefädelt.The first longitudinal slit 19, the second longitudinal slit 20, the third longitudinal slit 21, the fourth longitudinal slit 22 as well as the other longitudinal slits are each offset semi-cylindrically at one end, i.e. not designed to be continuous. The counterpart 13 is threaded into the clamping piece 11 by means of the first guide pin 14, the second guide pin 15 and the further guide pins as well as the first longitudinal slot 19, the second longitudinal slot 20, the third longitudinal slot 21, the fourth longitudinal slot 22 and the further longitudinal slots.

Aufgrund des ersten Führungszapfens 14, des zweiten Führungszapfens 15 und der weiteren Führungszapfen sowie des ersten Längsschlitzes 19, des zweiten Längsschlitzes 20, des dritten Längsschlitzes 21, des vierten Längsschlitzes 22 sowie der weiteren Längsschlitze ist das Gegenstück 13 in dem Spannstück 11 gegen unbeabsichtigte Bewegungen relativ zu dem Spannstück 11 gesichert.Due to the first guide pin 14, the second guide pin 15 and the further guide pins as well as the first longitudinal slot 19, the second longitudinal slot 20, the third longitudinal slot 21, the fourth longitudinal slot 22 and the further longitudinal slots, the counterpart 13 in the clamping piece 11 is relative against unintentional movements secured to the clamping piece 11.

Das Spannstück 11 weist eine erste Bohrung 27 auf, das Gegenstück 13 eine zweite Bohrung 28. In der ersten Bohrung 27 und der zweiten Bohrung 28 ist die Zentralschraube 12 geführt. Die zweite Bohrung 28 weist ein Innengewinde und die Zentralschraube 12 ein Außengewinde auf. Über das Außengewinde und das Innengewinde ist die Zentralschraube 12 mit dem Gegenstück 13 verschraubt.The clamping piece 11 has a first bore 27, the counterpart 13 has a second bore 28. In the first bore 27 and the second bore 28, the central screw 12 is guided. The second bore 28 has an internal thread and the central screw 12 has an external thread. The central screw 12 is screwed to the counterpart 13 via the external thread and the internal thread.

Wird die Zentralschraube 12 angezogen, so bewegt sich das Gegenstück 13 in Richtung einer Längsachse 29 des Spannstücks 11 in Richtung eines Schraubenkopfs 30 der Zentralschraube 12. Aufgrund einer Keilwirkung, welche zwischen dem konischen Innenraum 16 des Spannstücks 11 und dem konischen Gegenstück 13 ausgebildet wird, wird eine radiale Vorspannkraft, welche das Spannstück 11 im Bereich des konischen Innenraums 16 gegen das erste Hohlwellensegment 10 drückt, erzeugt.If the central screw 12 is tightened, the counterpart 13 moves in the direction of a longitudinal axis 29 of the clamping piece 11 in the direction of a screw head 30 of the central screw 12. Due to a wedge effect, which is formed between the conical interior 16 of the clamping piece 11 and the conical counterpart 13, a radial prestressing force, which presses the clamping piece 11 in the region of the conical interior space 16 against the first hollow shaft segment 10, is generated.

Aufgrund der Vorspannkraft wird der Presssitz zwischen dem Spannstück 11 und der ersten Radsatzwelle 3 erzeugt und es werden Kräfte und Momente (insbesondere Torsionsmomente und Biegemomente) zwischen der ersten Spannanordnung 7 und dem ersten Radsatz 1 übertragen.Due to the biasing force, the press fit between the clamping piece 11 and the first wheelset shaft 3 is generated and it forces and moments (in particular torsional moments and bending moments) are transmitted between the first clamping arrangement 7 and the first wheel set 1 .

Das Spannstück 11 ist an seinem in Fig. 1 rechts dargestellten Ende, d.h. im Bereich seines Auslaufs 17 ballig ausgeführt. Dadurch wird einerseits der Vorteil eines Toleranzausgleichs bei einem Einführen des Spannstücks 11 in das erste Hohlwellensegment 10 bzw. bei einem Vorspannen des Spannstücks 11 in dem ersten Hohlwellensegment 10 erzielt sowie andererseits eine kantige Auflage des Spannstücks 11 an einer Oberfläche des ersten Hohlwellensegments 10 und somit Beschädigungen vermieden.The clamping piece 11 is at its in 1 end shown on the right, ie in the region of its outlet 17 crowned. As a result, on the one hand, the advantage of tolerance compensation when inserting the clamping piece 11 into the first hollow shaft segment 10 or when pretensioning the clamping piece 11 in the first hollow shaft segment 10 is achieved, and on the other hand, an angular contact of the clamping piece 11 on a surface of the first hollow shaft segment 10 and thus damage avoided.

Auf dem Spannstück 11 ist mittels eines ersten Wälzlagerpaars 31 eine Tragevorrichtung 9 gelagert. Mittels einer Presspassung, eines auf dem Spannstück 11 vorgesehenen und mit dem Spannstück verschraubten Gewinderings 33 und einer Schulter 34 des Spannstücks 11 bzw. einer zwischen der Schulter 34 und dem ersten Wälzlagerpaar 31 auf dem Spannstück 11 angeordneten Dichtung 35 sowie einer entsprechend geformten Innenseite der Tragevorrichtung 9 ist das erste Wälzlagerpaar 31 auf dem Spannstück 11 fixiert. Mittels der Dichtung 35 und eines Deckels 36 ist das erste Wälzlagerpaar 31 gegen Umgebungseinflüsse wie Feuchtigkeit, Partikel etc. geschützt bzw. abgedichtet.A carrying device 9 is mounted on the clamping piece 11 by means of a first pair of roller bearings 31 . By means of a press fit, a threaded ring 33 provided on the clamping piece 11 and screwed to the clamping piece and a shoulder 34 of the clamping piece 11 or a seal 35 arranged between the shoulder 34 and the first pair of roller bearings 31 on the clamping piece 11 and a correspondingly shaped inside of the carrying device 9, the first pair of roller bearings 31 is fixed on the clamping piece 11. The first pair of roller bearings 31 is protected or sealed against environmental influences such as moisture, particles etc. by means of the seal 35 and a cover 36 .

Die Dichtung 35 ist mittels einer ersten Innensechskantschraube 37, einer zweiten Innensechskantschraube 38 sowie weiteren, nicht dargestellten Innensechskantschrauben mit der Tragevorrichtung 9 verschraubt. Der Deckel 36 ist mittels einer ersten Befestigungsschraube 39, einer zweiten Befestigungsschraube 40, einer dritten Befestigungsschraube 41, einer vierten Befestigungsschraube 42 sowie weiteren, nicht gezeigten Befestigungsschraube mit der Tragevorrichtung 9 verbunden. Der Deckel 36 weist ein Schauloch 23 auf, über das eine in Fig. 1 nicht gezeigte Verdrehmarkierung der Zentralschraube 12 inspiziert werden kann. Dadurch kann rasch überprüft werden, ob sich die Zentralschraube 12 unbeabsichtigt gelöst hat.The seal 35 is screwed to the carrying device 9 by means of a first Allen screw 37, a second Allen screw 38 and further Allen screws (not shown). The cover 36 is connected to the carrying device 9 by means of a first fastening screw 39, a second fastening screw 40, a third fastening screw 41, a fourth fastening screw 42 and further fastening screws (not shown). The cover 36 has an inspection hole 23 through which an in 1 not shown rotation mark of the central screw 12 can be inspected. This can be checked quickly whether the central screw 12 has unintentionally loosened.
