Description

Die Erfindung betrifft ein Fahrwerk für ein Schienenfahrzeug, mit zumindest einem Fahrwerksrahmen, an den zumindest ein erster Radsatz gekoppelt ist.The invention relates to a running gear for a rail vehicle, having at least one running gear frame to which at least a first wheel set is coupled.

Eine mechanisch entkoppelte Lagerung von Fahrwerkskomponenten (z.B. von Motoren, Getrieben oder Bremskomponenten von Schienenfahrzeugen) ist insbesondere bei hohen Fahrgeschwindigkeiten wichtig, da dynamische Reaktionen, welche beispielsweise aufgrund von Gleislagefehlern von einem Gleis auf Komponenten des Fahrwerks übertragen werden, mit zunehmender Geschwindigkeit an Intensität zunehmen. Weiterhin müssen bei einer Anordnung und Dimensionierung von Lagern von Fahrwerkskomponenten insbesondere bei innengelagerten Fahrwerken häufig stark eingeschränkte Bauraumbudgets berücksichtigt werden.A mechanically decoupled mounting of chassis components (e.g. of engines, transmissions or brake components of rail vehicles) is particularly important at high speeds, since dynamic reactions, which are transmitted from a track to components of the chassis due to track geometry errors, for example, increase in intensity with increasing speed. Furthermore, when arranging and dimensioning bearings for running gear components, particularly in the case of running gears with internal bearings, it is often necessary to take into account very limited installation space budgets.

Aus dem Stand der Technik beschreibt beispielsweise die WO 2017/133954 A1 ein innengelagertes Fahrwerk mit einem Fahrwerksrahmen, einem querliegenden Antriebsmotor und einem Getriebe. Zwischen dem Antriebsmotor und dem Fahrwerksrahmen sind zumindest drei elastische Lager angeordnet, wobei auf zumindest einem von zwei Längsträgern des Fahrwerksrahmens je eines dieser elastischen Lager vorgesehen ist.From the prior art, for example, describes the WO 2017/133954 A1 an internally mounted undercarriage with an undercarriage frame, a transverse drive motor and a gearbox. At least three elastic bearings are arranged between the drive motor and the chassis frame, with one of these elastic bearings each being provided on at least one of two longitudinal beams of the chassis frame.

In einer in der WO 2017/133954 A1 beschriebenen Ausführungsvariante ist ein als elastische Buchse ausgeführtes elastisches Lager dargestellt, welches in eine Bohrung eines Längsträgers des Fahrwerksrahmens eingesetzt ist.In one in the WO 2017/133954 A1 The embodiment variant described is an elastic bearing designed as an elastic bushing, which is inserted into a bore of a longitudinal member of the chassis frame.

Weiterhin ist die WO 2017/093094 A1 bekannt, in welcher ein Fahrwerk für ein Schienenfahrzeug mit einem Fahrwerksrahmen, Radsätzen und Antriebseinheiten dargestellt ist. Die Antriebseinheiten sind in einen Querträger des Fahrwerksrahmens integriert.Furthermore, the WO 2017/093094 A1 known, in which a chassis for a rail vehicle with a chassis frame, wheelsets and drive units is shown. The drive units are integrated in a cross member of the chassis frame.

Die genannten Ansätze weisen in ihren bekannten Formen den Nachteil auf, dass entweder kein stark ausgeprägtes Federungsverhalten des Antriebsmotors zu erwarten ist oder dass eine Montage und Demontage der Antriebseinheiten einen hohen Aufwand verursacht.In their known forms, the approaches mentioned have the disadvantage that either no pronounced spring behavior of the drive motor is to be expected or that assembly and disassembly of the drive units causes a great deal of effort.

Ferner beschreibt die CN 104 670 263 A ein Fahrwerk für ein Schienenfahrzeug, bei welchem ein zentraler Längsmitnahmebolzen über eine Elastomerbuchse in einer Ausnehmung eines Bolzenhalters, welcher mit einem Fahrwerksrahmen verbunden ist, gelagert ist.Also describes the CN 104 670 263 A a bogie for a rail vehicle, in which a central longitudinal driving bolt is mounted via an elastomer bushing in a recess of a bolt holder, which is connected to a bogie frame.

In der EP 0 420 801 A1 ist ein Fahrwerk dargestellt, bei welchem zwei Antriebseinheiten über Anschlussteile mit einem Querträger eines Fahrwerksrahmens verbunden sind. Die Anschlussteile sind über ein elastisches Gelenk miteinander verbunden und ragen in eine Durchtrittsöffnung des Querträgers.In the EP 0 420 801 A1 a chassis is shown in which two drive units are connected to a cross member of a chassis frame via connection parts. The connecting parts are connected to one another via an elastic joint and protrude into a passage opening in the cross member.

Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber dem Stand der Technik weiterentwickeltes Fahrwerk mit einer kompakten aber dennoch stark vibrationssenkenden und gut zugänglichen Komponentenlagerung anzugeben.The invention is therefore based on the object of specifying a chassis which has been developed further in comparison with the prior art and has a component bearing that is compact but nevertheless greatly reduces vibration and is easily accessible.

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, dass die erste Lagervorrichtung in die erste Ausnehmung hineinragt und nicht vollständig gekapselt ist, wird eine einfache und wenig zeitaufwendige Wartung und Instandhaltung der Fahrwerkskomponente erzielt. Für eine Demontage muss die Fahrwerkskomponente lediglich aus der Ausnehmung ausgefädelt werden und kann danach unmittelbar von dem Fahrwerk entfernt werden. Die erste Lagervorrichtung kann mit der Fahrwerkskomponente verbunden bleiben.Because the first bearing device protrudes into the first recess and is not completely encapsulated, simple and less time-consuming servicing and maintenance of the chassis component is achieved. For disassembly, the chassis component only has to be threaded out of the recess and can then be removed directly from the chassis. The first bearing device can remain connected to the chassis component.

Durch eine teilweise Anordnung der ersten Lagervorrichtung in dem ersten Träger in einem eingebauten Zustand der Fahrwerkskomponente wird eine besonders platzsparende Anordnung der Fahrwerkskomponente bewirkt.Partial arrangement of the first bearing device in the first support when the chassis component is installed results in a particularly space-saving arrangement of the chassis component.

Die erste Ausnehmung ist in dem ersten Träger vorgesehen, wodurch beispielsweise auf Konsolen, welche mit dem Fahrwerksrahmen verschweißt sind, verzichtet werden kann und dennoch ausreichender Bauraum erzielt wird, um die in der Ausnehmung angeordnete erste Federvorrichtung großzügig dimensionieren zu können.The first recess is provided in the first support, which means that brackets, for example, which are welded to the chassis frame, can be dispensed with and yet sufficient installation space is achieved in order to be able to generously dimension the first spring device arranged in the recess.

Dadurch kann ferner, bei entsprechender Anordnung und Erstreckung der ersten Öffnung bis zu einer Vorderkante des ersten Trägers, eine Vergrößerung der ersten Ausnehmung ermöglicht werden, wozu lediglich der erste Deckel demontiert werden muss. Die Vergrößerung der ersten Ausnehmung bewirkt wiederum eine Aufwandsverringerung bei Demontage und Montage der Fahrwerkskomponente.As a result, with a corresponding arrangement and extent of the first opening up to a front edge of the first carrier, an enlargement of the first recess can also be made possible, for which purpose only the first cover has to be dismantled. The enlargement of the first recess in turn results in a reduction in effort when disassembling and assembling the chassis component.

Erfindungsgemäß ist die erste Ausnehmung aus einem ersten Gurt, einem zweiten Gurt, einem Steg sowie aus einer ersten Seitenwand und einer zweiten Seitenwand gebildet.According to the invention, the first recess is formed from a first chord, a second chord, a web and from a first side wall and a second side wall.

Durch diese Maßnahme wird eine vorhandene Profilgeometrie des Trägers effizient zur Ausbildung der ersten Ausnehmung genutzt.As a result of this measure, an existing profile geometry of the carrier is used efficiently to form the first recess.

Eine vorteilhafte Ausgestaltung erhält man, wenn die zumindest erste Federvorrichtung als Schichtfeder ausgeführt ist.An advantageous embodiment is obtained when the at least first spring device is designed as a layered spring.

Dadurch werden eine Eigendämpfung sowie eine akustische Dämpfung der ersten Federvorrichtung bewirkt.As a result, self-damping and acoustic damping of the first spring device are brought about.

Eine günstige Lösung wird erreicht, wenn die zumindest erste Lagervorrichtung mit einer zweiten Federvorrichtung verbunden ist, wobei die zumindest erste Federvorrichtung über eine erste Kontaktzone der zumindest ersten Lagervorrichtung mit der zumindest ersten Lagervorrichtung verbunden ist und die zweite Federvorrichtung über eine zweite Kontaktzone der zumindest ersten Lagervorrichtung mit der zumindest ersten Lagervorrichtung verbunden ist, wobei die erste Kontaktzone der zweiten Kontaktzone gegenüberliegend angeordnet ist. Durch diese Maßnahme wird einerseits eine besonders effektive Federung erzielt und andererseits, durch Anordnung der ersten Lagervorrichtung zwischen der ersten Federvorrichtung und der zweiten Federvorrichtung, ein Schutz der ersten Lagervorrichtung vor übermäßigen Belastungen.A favorable solution is achieved if the at least first bearing device is connected to a second spring device, the at least first spring device being connected to the at least first bearing device via a first contact zone of the at least first bearing device and the second spring device being connected to the at least first bearing device via a second contact zone is connected to the at least first bearing device, wherein the first contact zone is arranged opposite the second contact zone. On the one hand, this measure achieves a particularly effective suspension and, on the other hand, by arranging the first bearing device between the first spring device and the second spring device, the first bearing device is protected against excessive loads.

Erfindungsgemäß ist die zumindest erste Federvorrichtung in die zumindest erste Öffnung hineinragend und den ersten Deckel kontaktierend angeordnet.According to the invention, the at least first spring device projects into the at least first opening and is arranged in contact with the first cover.

Durch diese Maßnahme wird der erste Träger von Federreaktionen aus der ersten Federvorrichtung zumindest teilweise entlastet. Eine Versteifung des ersten Trägers im Bereich der ersten Ausnehmung ist nicht erforderlich oder muss zumindest lediglich schwach ausgeprägt sein, da zumindest ein Teil der Federreaktionen nicht in den ersten Träger, sondern in den Deckel eingeleitet werden.This measure at least partially relieves the first carrier of spring reactions from the first spring device. A stiffening of the first carrier in the area of the first recess is not necessary or at least only has to be weakly pronounced, since at least some of the spring reactions are not introduced into the first carrier but into the cover.

Weiterhin wird dadurch bei Montage des ersten Deckels eine Vorspannung in der ersten Federvorrichtung aufgebaut und bei Demontage des ersten Deckels die Vorspannung abgebaut. Nachfolgend wird die Erfindung anhand von Ausführungsbeispielen näher erläutert.Furthermore, as a result, when the first cover is installed, a preload is built up in the first spring device and when the first cover is removed, the preload is reduced. The invention is explained in more detail below using exemplary embodiments.

Furthermore, the first wheel set 9 is connected to the running gear frame 1 via the first primary spring 7 and the second primary spring 8 and via two wheel set guide devices (not shown).

Das Getriebe 3 weist eine Getriebehohlwelle 13 auf, die mantelförmig um die Radsatzwelle 12 angeordnet ist. Eine Abtriebskupplung 14 ist ebenfalls mantelförmig um die Radsatzwelle 12 angeordnet und formschlüssig mit der Getriebehohlwelle 13 verbunden.The transmission 3 has a transmission hollow shaft 13 which is arranged in the form of a jacket around the wheelset shaft 12 . An output clutch 14 is also arranged in the form of a jacket around the wheelset shaft 12 and is connected to the hollow transmission shaft 13 in a form-fitting manner.

Die Abtriebskupplung 14 ist entsprechend dem verfügbaren Stand der Technik ausgeführt und ermöglicht Relativbewegungen zwischen dem Antriebsmotor 2 und dem Getriebe 3 einerseits und dem ersten Radsatz 9 andererseits.The output clutch 14 is designed according to the available prior art and allows relative movements between the drive motor 2 and the transmission 3 on the one hand and the first wheel set 9 on the other.

Rotationsbewegungen und Drehmomente einer nicht gezeigten Antriebswelle des Antriebsmotors 2 werden über das Getriebe 3, die Getriebehohlwelle 13 und die Abtriebskupplung 14 auf die Radsatzwelle 12 übertragen.Rotational movements and torques of a drive shaft, not shown, of the drive motor 2 are transmitted to the wheel set shaft 12 via the gear 3, the hollow gear shaft 13 and the output clutch 14 .

Die Antriebseinheit 15 ist über eine erste Lagervorrichtung 16 und eine zweite Lagervorrichtung 17 federnd an den ersten Träger 4 und somit an den Fahrwerksrahmen 1 gekoppelt.The drive unit 15 is resiliently coupled to the first carrier 4 and thus to the running gear frame 1 via a first bearing device 16 and a second bearing device 17 .

Dabei handelt es sich um eine günstige Lösung. Erfindungsgemäß ist es jedoch auch vorstellbar, dass die Antriebseinheit 15 über die erste Lagervorrichtung 16 und die zweite Lagervorrichtung 17 beispielsweise mit dem zweiten Träger 5, mit dem dritten Träger 6 oder, insbesondere bei Fahrwerken für Lokomotiven, mit einem Fahrwerks-Kopfträger verbunden sind.This is a cheap solution. According to the invention, however, it is also conceivable for the drive unit 15 to be connected via the first bearing device 16 and the second bearing device 17, for example to the second carrier 5, to the third carrier 6 or, in particular in the case of bogies for locomotives, to a bogie head carrier.

Weiterhin ist es denkbar, dass der Antriebsmotor 2 und das Getriebe 3 unabhängig voneinander auf dem Fahrwerksrahmen 1 gelagert sind, wobei dem Antriebsmotor 2 die erste Lagervorrichtung 16 und dem Getriebe 3 die zweite Lagervorrichtung 17 zugeordnet ist.It is also conceivable that the drive motor 2 and the transmission 3 are mounted independently of one another on the chassis frame 1 , with the drive motor 2 being assigned the first bearing device 16 and the transmission 3 being assigned the second bearing device 17 .

Die erste Lagervorrichtung 16 ist einstückig mit dem als metallisches Gussteil ausgebildeten Motor-Gehäuseteil, die zweite Lagervorrichtung 17 einstückig mit dem ebenfalls als Metallgussteil ausgeführten Getriebe-Gehäuseteil ausgebildet. Erfindungsgemäß ist es jedoch auch vorstellbar, die erste Lagervorrichtung 16 mit dem Motor-Gehäuseteil und die zweite Lagervorrichtung 17 mit dem Getriebe-Gehäuseteil zu verschrauben, zu verschweißen etc.The first bearing device 16 is formed in one piece with the motor housing part, which is designed as a metal casting, and the second bearing device 17 is formed in one piece with the transmission housing part, which is also designed as a metal casting. According to the invention, however, it is also conceivable to screw, weld, etc., the first bearing device 16 to the motor housing part and the second bearing device 17 to the transmission housing part.

Die erste Lagervorrichtung 16 ist in eine auch im Zusammenhang mit Fig. 2 beschriebene erste Ausnehmung 18 des ersten Trägers 4, die zweite Lagervorrichtung 17 in eine zweite Ausnehmung 19 des ersten Trägers 4 hineinragend angeordnet.The first storage device 16 is also related to a 2 described first recess 18 of the first carrier 4, the second bearing device 17 is arranged projecting into a second recess 19 of the first carrier 4.

Unterhalb der ersten Lagervorrichtung 16 ist eine in Fig. 2 sichtbare erste Federvorrichtung 20 vorgesehen und mit einer Unterseite der ersten Lagervorrichtung 16 verbunden.

Translationsbewegungen der Antriebseinheit 15 in Längsrichtung, in Querrichtung und in vertikaler Richtung sind aufgrund der ersten Federvorrichtung 20, der zweiten Federvorrichtung 21, der dritten Federvorrichtung 22 und der vierten Federvorrichtung effektiv gefedert. Weiterhin erfolgt eine Federung gewisser Dreh- bzw. Schwenkbewegungen der Antriebseinheit 15 (beispielsweise um eine quer zu einer Fahrtrichtung des Fahrwerks verlaufende Achse).Translational movements of the drive unit 15 in the longitudinal, transverse and vertical directions are effectively sprung due to the first spring device 20, the second spring device 21, the third spring device 22 and the fourth spring device. Furthermore, certain rotational or pivoting movements of the drive unit 15 are spring-loaded (for example about an axis running transversely to a direction of travel of the running gear).

Mittels der ersten Lagervorrichtung 16 und der zweiten Lagervorrichtung 17 ist in dieser beispielhaften Variante eines erfindungsgemäßen Fahrwerks eine als Antriebseinheit 15 ausgebildete Fahrwerkskomponente an den Fahrwerksrahmen 1 gekoppelt, wobei es sich um eine günstige Lösung handelt. Erfindungsgemäß ist es jedoch auch denkbar, dass andere bzw. weitere Fahrzeugkomponenten (z.B. Bremskomponenten wie Bremszylinder mit Bremshebeln, Antennenträger etc.), wie im Zusammenhang mit Fig. 1 beschrieben, in Ausnehmungen von Trägern des Fahrwerksrahmens 1 hineinragend und federnd gelagert sind.In this exemplary variant of a running gear according to the invention, a running gear component designed as a drive unit 15 is coupled to the running gear frame 1 by means of the first bearing device 16 and the second bearing device 17 , which is a favorable solution.

In Fig. 2 ist ein Ausschnitt aus einem ersten Träger 4 eines Fahrwerksrahmens 1, welcher Teil einer beispielhaften Variante eines erfindungsgemäßen Fahrwerks für ein Schienenfahrzeug ist und auch in Fig. 1 gezeigt ist, als Seitenriss offenbart.In 2 is a section of a first carrier 4 of a running gear frame 1, which is part of an exemplary variant of a running gear according to the invention for a rail vehicle and also in 1 shown is disclosed in side elevation.

Der erste Träger 4 ist als Querträger des Fahrwerksrahmens 1 ausgebildet und weist ein Doppel-T-Profil auf. Erfindungsgemäß ist es jedoch auch vorstellbar, dass der erste Träger 4 beispielsweise als Längsträger oder, insbesondere bei Fahrwerken für Lokomotiven, als Kopfträger ausgeführt ist.The first support 4 is designed as a cross member of the running gear frame 1 and has a double-T profile. According to the invention, however, it is also conceivable that the first carrier 4 is designed, for example, as a longitudinal carrier or, in particular in the case of running gears for locomotives, as a head carrier.

Der erste Träger 4 weist eine erste Ausnehmung 18 auf, welche aus einem als Untergurt ausgeführten ersten Gurt 23 des ersten Trägers 4, einem als Obergurt ausgebildeten zweiten Gurt 24 des ersten Trägers 4, einem Steg 25 des ersten Trägers 4 sowie aus einer ersten Seitenwand 26 und einer zweiten Seitenwand 27 gebildet ist.The first girder 4 has a first recess 18, which consists of a first chord 23 of the first girder 4 designed as a lower chord, a second chord 24 of the first girder 4 designed as an upper chord, a web 25 of the first girder 4 and a first side wall 26 and a second side wall 27 is formed.

Die erste Seitenwand 26 und die zweite Seitenwand 27 sind mit dem ersten Träger 4 verschweißt und fungieren als Versteifungsrippen des ersten Trägers 4.The first side wall 26 and the second side wall 27 are welded to the first beam 4 and act as stiffening ribs of the first beam 4.

Eine erste Lagervorrichtung 16 einer in Fig. 1 gezeigten Antriebseinheit 15 des Fahrwerks ist in die erste Ausnehmung 18 hineinragend angeordnet und über eine erste Kontaktzone 28 mit einer ersten Federvorrichtung 20 und über eine zweite Kontaktzone 29 mit einer zweiten Federvorrichtung 21 verbunden.A first storage device 16 of an in 1 The drive unit 15 of the running gear shown is arranged such that it projects into the first recess 18 and is connected to a first spring device 20 via a first contact zone 28 and to a second spring device 21 via a second contact zone 29 .

Die erste Kontaktzone 28 ist an einer Unterseite der ersten Lagervorrichtung 16 und der zweiten Kontaktzone 29, welche an einer Oberseite der ersten Lagervorrichtung 16 vorgesehen ist, gegenüberliegend angeordnet.The first contact zone 28 is arranged opposite one another on an underside of the first bearing device 16 and the second contact zone 29 which is provided on an upper side of the first bearing device 16 .

Die erste Federvorrichtung 20 und die zweite Federvorrichtung 21 sind als Schichtfedern ausgebildet.The first spring device 20 and the second spring device 21 are designed as layered springs.

Die erste Federvorrichtung 20 ist mit dem ersten Gurt 23 verbunden, die zweite Federvorrichtung 21 mit dem zweiten Gurt 24. Erfindungsgemäß kann zwischen der ersten Federvorrichtung 20 und dem ersten Gurt 23 auch ein erster Gummipuffer, zwischen der zweiten Federvorrichtung 21 und dem zweiten Gurt 24 auch ein zweiter Gummipuffer vorgesehen sein.The first spring device 20 is connected to the first strap 23, the second spring device 21 to the second strap 24. According to the invention, a first rubber buffer can also be placed between the first spring device 20 and the first strap 23, and between the second spring device 21 and the second strap 24 as well a second rubber buffer can be provided.

Der erste Träger 4 weist im Bereich der ersten Ausnehmung 18 eine zylindrische erste Öffnung 30 auf, welche mittels eines ersten Deckels 31 verschlossen ist.In the area of the first recess 18 the first carrier 4 has a cylindrical first opening 30 which is closed by means of a first cover 31 .

Die erste Öffnung 30 ist in dem ersten Gurt 23 vorgesehen, erstreckt sich in vertikaler Richtung und erweitert die erste Ausnehmung 18 nach unten und nach vorne.The first opening 30 is provided in the first strap 23, extends in the vertical direction, and widens the first recess 18 downward and forward.

Im Bereich der ersten Öffnung 30 ist die erste Federvorrichtung 20 teilweise von dem ersten Gurt 23 ummantelt.In the area of the first opening 30 the first spring device 20 is partially encased by the first strap 23 .

Die erste Federvorrichtung 20 ist in die erste Öffnung 30 hineinragend sowie den ersten Deckel 31 kontaktierend angeordnet und belastet den ersten Deckel 31 mit Federreaktionen.The first spring device 20 projects into the first opening 30 and contacts the first cover 31 arranged and loads the first cover 31 with spring reactions.

Der erste Deckel 31 weist daher eine entsprechende Festigkeit auf und ist schubsteif mit dem ersten Gurt 23 verbunden. Zwischen dem ersten Deckel 31 und dem ersten Gurt 23 sind eine erste Schraube 32, eine zweite Schraube 33 sowie in Fig. 2 nicht sichtbare weitere Schrauben mit entsprechender Steifigkeit vorgesehen.The first cover 31 therefore has a corresponding strength and is connected to the first belt 23 in a shear-resistant manner. Between the first cover 31 and the first strap 23 are a first screw 32, a second screw 33 and 2 non-visible additional screws with appropriate rigidity are provided.

In der ersten Ausnehmung 18, zwischen dem ersten Träger 4 und der ersten Federvorrichtung 20, konkret zwischen dem ersten Träger 4 und einer Mantelfläche der ersten Federvorrichtung 20, ist ein ringförmiger Anschlag 34 aus Gummi vorgesehen, welcher die erste Federvorrichtung 20 umgibt und mit Schraubenenden der ersten Schraube 32, der zweiten Schraube 33 und der weiteren Schrauben verbunden ist. Dadurch werden seitliche Auslenkungen der ersten Lagervorrichtung 16 begrenzt.In the first recess 18, between the first carrier 4 and the first spring device 20, specifically between the first carrier 4 and a lateral surface of the first spring device 20, an annular stop 34 made of rubber is provided, which surrounds the first spring device 20 and is connected to screw ends of the first screw 32, the second screw 33 and the other screws is connected. As a result, lateral deflections of the first bearing device 16 are limited.

Bei einer Demontage der Antriebseinheit 15 werden die erste Schraube 32, die zweite Schraube 33 und die weiteren Schrauben gelöst und mit dem ersten Deckel 31 von dem ersten Träger 4 entfernt. Dadurch wird eine Vorspannung der ersten Federvorrichtung 20 und der zweiten Federvorrichtung 21 abgebaut.When dismantling the drive unit 15, the first screw 32, the second screw 33 and the other screws are loosened and removed with the first cover 31 from the first carrier 4. As a result, a bias of the first spring device 20 and the second spring device 21 is reduced.

Danach wird die erste Lagervorrichtung 16 mit der ersten Federvorrichtung 20 und der zweiten Federvorrichtung 21 über die erste Öffnung 30 nach unten aus der ersten Ausnehmung 18 ausgefädelt.Thereafter, the first bearing device 16 with the first spring device 20 and the second spring device 21 is threaded out downwards from the first recess 18 via the first opening 30 .

Bei einer Montage der Antriebseinheit 15 wird die erste Lagervorrichtung 16 mit der ersten Federvorrichtung 20 und der zweiten Federvorrichtung 21 über die erste Öffnung 30 von unten in die erste Ausnehmung 18 eingefädelt und darin gehalten.When the drive unit 15 is assembled, the first bearing device 16 with the first spring device 20 and the second spring device 21 is threaded into the first recess 18 from below via the first opening 30 and is held therein.

Danach wird der erste Deckel 31 von unten an den ersten Gurt 23 angelegt und es werden die erste Schraube 32, die zweite Schraube 33 und die weiteren Schrauben in entsprechende Bohrungen in dem ersten Deckel 31 und in dem ersten Gurt 23 eingeführt und angezogen. Dadurch werden der erste Deckel 31 gegen den ersten Gurt 23 verspannt, die erste Federvorrichtung 20 und die zweite Federvorrichtung 21 vorgespannt und die erste Lagervorrichtung 16, die erste Federvorrichtung 20 sowie die zweite Federvorrichtung 21 in der ersten Ausnehmung 18 gesichert.Thereafter, the first cover 31 is applied from below to the first belt 23 and there are the first screw 32, the second screw 33 and the other screws in corresponding Holes in the first cover 31 and in the first belt 23 introduced and tightened. As a result, the first cover 31 is clamped against the first belt 23, the first spring device 20 and the second spring device 21 are prestressed and the first bearing device 16, the first spring device 20 and the second spring device 21 are secured in the first recess 18.

Der Anschlag 34 ist durchbrochen ausgeführt, damit er vor der Demontage der ersten Lagervorrichtung 16 demontiert und ausgefädelt sowie nach der Montage der ersten Lagervorrichtung 16 eingefädelt und montiert werden kann.The stop 34 is perforated so that it can be dismantled and unthreaded before the first bearing device 16 is dismantled and it can be threaded in and assembled after the first bearing device 16 has been assembled.

Erfindungsgemäß ist es auch vorstellbar, dass die erste Öffnung 30 vollständig von dem ersten Gurt 23 umschlossen ist, d.h. die erste Ausnehmung 18 nicht nach vorne erweitert, wodurch die Lagervorrichtung 16 bei einer Demontage nach vorne aus der ersten Ausnehmung 18 ausgefädelt und bei einer Montage von vorne in die erste Ausnehmung 18 eingefädelt werden muss.According to the invention, it is also conceivable that the first opening 30 is completely surrounded by the first belt 23, i.e. the first recess 18 does not widen towards the front, whereby the bearing device 16 is threaded out of the first recess 18 towards the front during disassembly and, during assembly of must be threaded into the first recess 18 at the front.

Die erste Öffnung 30 ist in dem ersten Gurt 23 vorgesehen. Erfindungsgemäß ist es jedoch auch denkbar, dass als Alternative oder zusätzlich in dem zweiten Gurt 24 eine zweite Öffnung vorgesehen ist, welche von einem zweiten Deckel verschlossen ist, wobei die zweite Federvorrichtung 21 in die zweite Öffnung hineinragend und den zweiten Deckel kontaktierend angeordnet ist.The first opening 30 is provided in the first strap 23 . According to the invention, however, it is also conceivable that, as an alternative or in addition, a second opening is provided in the second belt 24, which is closed by a second cover, the second spring device 21 being arranged protruding into the second opening and contacting the second cover.
