Description

Die Erfindung betrifft eine Anordnung zur Abstützung eines Drehmoments eines Getriebes eines Schienenfahrzeugs.The invention relates to an arrangement for supporting a torque of a transmission of a rail vehicle.

Eine Abstützung eines Drehmoments erfolgt durch eine Drehmomentstütze, die als bekanntes Maschinenelement ein Bestandteil einer Aufhängung eines Getriebes ist.A torque is supported by a torque support, which is a known machine element and is part of the suspension of a transmission.

Ein Getriebe ist ein Maschinenelement, mit dem Bewegungsgrößen geändert werden. Es besitzt einen so genannten Antrieb, an dem eine Bewegungsgröße eingespeist wird, sowie einen so genannten Abtrieb, an dem eine Bewegungsgröße ausgegeben wird.A gear is a machine element that is used to change movement variables. It has a so-called drive, to which a movement variable is fed in, and a so-called output, to which a movement variable is output.

FIG 3 zeigt in einer ersten Ansicht eine Drehmomentstütze DMS bei einem Getriebe GET eines Schienenfahrzeugs gemäß dem bekannten Stand der Technik. FIG 3 shows a first view of a torque support DMS in a GET transmission of a rail vehicle according to the known prior art.

Beim Schienenfahrzeug ist der Antrieb des Getriebes GET mit einem Motor MOT verbunden, während der Abtrieb des Getriebes GET mit einem Radantriebssystem RAS verbunden ist.In the rail vehicle, the drive of the transmission GET is connected to a motor MOT, while the output of the transmission GET is connected to a wheel drive system RAS.

Die Drehmomentstütze DMS wird dazu verwendet, ein Differenzdrehmoment von Antrieb und Abtrieb durch Abstützung aufzufangen bzw. dieses Differenzdrehmoment in eine Tragestruktur, hier beispielsweise in einen Rahmen RAH, einzuleiten.The torque support DMS is used to absorb a differential torque between the drive and output by supporting it or to introduce this differential torque into a support structure, here for example into a frame RAH.

Die Drehmomentstütze DMS ist funktionell als Hebel ausgebildet, der das Gehäuse des Getriebes außerhalb der Drehachse des Getriebes mit der Tragestruktur (hier beispielsweise den Rahmen RAH) verbindet.The DMS torque arm is functionally designed as a lever that connects the housing of the transmission outside the rotation axis of the transmission with the support structure (here, for example, the frame RAH).

FIG 4 zeigt mit Bezug auf FIG 3 in einer zweiten Ansicht weitere Verbindungsdetails. FIG 4 shows with reference to FIG 3 in a second view, further connection details.

Die Drehmomentstütze DMS ist an ihrem ersten Ende mit dem Getriebe GET verbunden.The torque support DMS is connected to the gearbox GET at its first end.

Die Drehmomentstütze DMS ist an ihrem zweiten Ende mit dem Motor MOT verbunden.The torque support DMS is connected to the motor MOT at its second end.

Der Motor MOT ist hier beispielhaft über zwei Befestigungspunkte BEF1, BEF2 mit dem Rahmen RAH verbunden, der als Tragestruktur ausgebildet und verwendet ist.The motor MOT is here, for example, connected via two attachment points BEF1, BEF2 to the frame RAH, which is designed and used as a support structure.

Durch diese Verbindungen bzw. durch diese Anordnung wird das oben genannte Differenzdrehmoment aufgefangen bzw. in den Rahmen eingeleitet.Through these connections or through this arrangement, the above-mentioned differential torque is absorbed or introduced into the frame.

Der Motor des Schienenfahrzeugs hat zwei Rotationsrichtungen. Die Drehmomentstütze DMS muss daher Differenzdrehmomente von zwei Rotationsrichtungen auffangen bzw. abstützen.The rail vehicle engine has two directions of rotation. The torque support DMS must therefore absorb or support differential torques from two directions of rotation.

Als Drehmomentstütze DMS werden massive Stangen verwendet, die durch elastische Lager mit dem Motor MOT bzw. mit dem Getriebe GET verbunden sind. Dadurch wird erreicht, dass Relativbewegungen dieser Bauteile ermöglicht werden.Solid rods are used as the DMS torque support, which are connected to the MOT motor or GET gearbox via elastic bearings. This ensures that relative movements of these components are made possible.

Als elastische Lager werden üblicherweise Elastomere-Lager verwendet, die in dieser Darstellung als Teilkreise an den beiden Enden der Drehmomentstütze DMS gezeigt sind. Es ist zu sehen, dass diese Lager einen bedeutenden Bauraum beanspruchen.Elastomeric bearings are usually used as elastic bearings, which are shown in this illustration as partial circles at the two ends of the DMS torque arm. It can be seen that these bearings take up a significant amount of space.

Die stangenförmige Drehmomentstütze DMS muss aufgrund der beiden Rotationsrichtungen sowohl Zugkräfte als auch Drucckräfte übertragen, was eine sehr massive Bauweise der Drehmomentstütze DMS bedingt. Diese massive Bauweise beansprucht wiederum einen bedeutenden Bauraum und hat zugleich ein erhöhtes Gewicht zur Folge.The rod-shaped torque arm DMS has to transmit both tensile forces and compressive forces due to the two directions of rotation, which requires a very solid construction of the torque arm DMS. This massive construction takes up a significant amount of space and at the same time results in increased weight.

Sowohl Bauraum als auch Gewicht müssen im Design und in der Dimensionierung des Schienenfahrzeugs berücksichtigt werden.Both installation space and weight must be taken into account in the design and dimensioning of the rail vehicle.

Auch aus Druckschrift DE 102013210235 A1 ist eine einteilige, stabförmige Drehmomentstütze für ein Schienenfahrzeug bekannt, die aus einem Faserverbund-Werkstoff gefertigt ist und zur Übertragung von Zugkräften und Druckkräften verwendet wird.Also from print DE 102013210235 A1 a one-piece, rod-shaped torque arm for a rail vehicle is known, which is made of a fiber composite material and is used to transmit tensile forces and compressive forces.

Es ist daher die Aufgabe der vorliegenden Erfindung, eine Anordnung zur Abstützung eines Drehmoments anzugeben, die mit Blick auf Gewicht und Bauraum optimiert ist.It is therefore the object of the present invention to provide an arrangement for supporting a torque that is optimized with regard to weight and installation space.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen sind in den abhängigen Ansprüchen angegeben.This task is solved by the features of claim 1. Advantageous further developments are specified in the dependent claims.

Die Erfindung betrifft eine Anordnung zur Abstützung eines Drehmoments eines Getriebes eines Schienenfahrzeugs. Die Anordnung weist folgende Elemente auf:

  • einen Motor, der zum Antrieb eines Rads des Schienenfahrzeugs ausgebildet ist,
  • ein Getriebe, das zwischen dem Motor und dem Rad angeordnet und mit beiden gekoppelt ist, um eine Antriebskraft des Motors auf das Rad zu übertragen,
  • eine Tragestruktur des Schienenfahrzeugs und
  • eine Drehmomentstütze, die mit dem Getriebe und mit der Tragestruktur verbunden ist, um ein Differenzdrehmoment des Getriebes in die Tragestruktur einzuleiten.
The invention relates to an arrangement for supporting a torque of a transmission of a rail vehicle. The arrangement has the following elements:
  • a motor which is designed to drive a wheel of the rail vehicle,
  • a transmission arranged between the motor and the wheel and coupled to both to transmit a driving force of the motor to the wheel,
  • a supporting structure of the rail vehicle and
  • a torque support that is connected to the transmission and to the support structure in order to introduce a differential torque of the transmission into the support structure.

Erfindungsgemäß weist die Drehmomentstütze zwei Faserelemente als Zugelemente auf, die zur ausschließlichen Übertragung von Zugkräften ausgebildet sind. Anschlusspunkte eines ersten Faserelements sind derart gewählt, dass das erste Faserelement eine aus dem Differenzdrehmoment resultierende erste Zugkraft einer ersten Rotationsrichtung des Motors in die Tragestruktur einleitet. Entsprechend sind Anschlusspunkte eines zweiten Faserelements derart gewählt, dass das zweite Faserelement eine aus dem Differenzdrehmoment resultierende zweite Zugkraft einer zweiten Rotationsrichtung des Motors in die Tragestruktur einleitet.According to the invention, the torque arm has two fiber elements as tension elements, which are designed for the exclusive transmission of tensile forces. Connection points of a first fiber element are selected such that the first fiber element introduces a first tensile force resulting from the differential torque of a first rotation direction of the motor into the support structure. Accordingly, connection points of a second fiber element are selected such that the second fiber element introduces a second tensile force resulting from the differential torque in a second direction of rotation of the motor into the support structure.

Bei der vorliegenden Erfindung bezeichnet der Begriff "Rad" sowohl ein angetriebenes Rad als auch einen angetriebenen Radsatz.In the present invention, the term "wheel" refers to both a driven wheel and a driven wheelset.

In einer vorteilhaften Weiterbildung ist die Tragestruktur ein Rahmen des Schienenfahrzeugs.In an advantageous development, the support structure is a frame of the rail vehicle.

In einer vorteilhaften Weiterbildung verbinden die beiden Faserelemente als Drehmomentstütze das Gehäuse des Getriebes außerhalb der Drehachse des Getriebes mit der Tragestruktur.In an advantageous development, the two fiber elements act as a torque support and connect the housing of the gearbox to the support structure outside the axis of rotation of the gearbox.

In einer vorteilhaften Weiterbildung weist der Motor zwei Rotationsrichtungen auf und die Drehmomentstütze ist derart ausgebildet, dass sie Differenzdrehmomente der beiden Rotationsrichtungen in die Tragestruktur einleitet.In an advantageous development, the motor has two directions of rotation and the torque support is designed such that it introduces differential torques of the two directions of rotation into the support structure.

In einer vorteilhaften Weiterbildung ist ein Antrieb des Getriebes mit dem Motor verbunden und ein Abtrieb des Getriebes ist mit dem anzutreibenden Rad bzw. Radsatz gekoppelt.In an advantageous development, a drive of the transmission is connected to the motor and an output of the transmission is coupled to the wheel or wheel set to be driven.

Erfindungsgemäß verbindet das erste Faserelement den Motor mit dem Getriebe, während das zweite Faserelement das Getriebe mit der Tragestruktur verbindet. Der Motor ist über Befestigungspunkte mit der Tragestruktur verbunden.According to the invention, the first fiber element connects the motor to the transmission, while the second fiber element connects the transmission to the support structure. The motor is connected to the support structure via attachment points.

In einer vorteilhaften Weiterbildung sind die beiden Faserelemente aus Faserwerkstoffen, bevorzugt aus Kevlar-Fasern und/oder aus Carbon-Fasern, gefertigt.In an advantageous development, the two fiber elements are made from fiber materials, preferably from Kevlar fibers and/or carbon fibers.

Durch die vorliegende Erfindung wird Gewicht eingespart. Die Faserelemente bzw. Zugelemente übertragen die jeweiligen Zugkräfte mit einem deutlich geringeren Gewicht im Vergleich zu den massiven Drehmomentstützen des beschriebenen Stands der Technik.The present invention saves weight. The fiber elements or tension elements transmit the respective tensile forces with a significantly lower weight compared to the solid torque supports of the prior art described.

Diese Gewichtsersparnis ist insbesondere bei einer ungefederten Masse eines Schienenfahrzeugs vorteilhaft, insbesondere bei einer Verwendung von achsreitenden Getrieben.This weight saving is particularly advantageous when the mass of a rail vehicle is unsprung, particularly when using axle-riding gears.

Zusätzlich sind die Faserelemente bzw. Zugelemente weniger massiv ausgestaltet als die beschriebenen Drehmomentstützen des Stands der Technik. Damit wird Bauraum eingespart bzw. frei.In addition, the fiber elements or tension elements are designed to be less massive than the described torque supports of the prior art. This saves or frees up installation space.

Durch die vorliegende Erfindung werden Elastomere-Lager eingespart und damit weiterer Bauraum gewonnen. Dies wird erreicht, da die erste Aufgabe der Elastomere-Lager, Relativbewegungen zuzulassen, von den Faserelemente grundsätzlich erfüllt wird. Für eine zweite Aufgabe der Elastomere-Lager, definierte Steifigkeiten in die Verbindung einzubringen, können weiterhin Elastomere-Lager verwendet werden, idealerweise mit geringeren Abmessungen. Für diese zweite Aufgabe können jedoch auch weiter Elemente, welch definierte Steifigkeiten aufweisen, verwendet werden.The present invention saves elastomer bearings and thus gains additional installation space. This is achieved because the first task of the elastomer bearings, to allow relative movements, is fundamentally fulfilled by the fiber elements. For a second task of the elastomeric bearings, namely to introduce defined stiffness into the connection, elastomeric bearings can still be used, ideally with smaller dimensions. However, other elements that have defined rigidities can also be used for this second task.

Die erzielbare, beträchtliche Einsparung an Bauraum ist insbesondere bei den relativ komprimierten Drehgestell-Lösungen vorteilhaft.The considerable savings in installation space that can be achieved are particularly advantageous in the case of relatively compressed bogie solutions.

Beim Schienenfahrzeug ist der Antrieb des Getriebes GET mit einem Motor MOT verbunden, während der Abtrieb des Getriebes GET mit einem Radantriebssystem RAS verbunden ist.In the rail vehicle, the drive of the transmission GET is connected to a motor MOT, while the output of the transmission GET is connected to a wheel drive system RAS.

Als Drehmomentstütze werden zwei Faserelemente bzw. Zugelemente FE1, FE2 verwendet, durch die das Differenzdrehmoment von Antrieb und Abtrieb in eine Tragestruktur, hier beispielsweise in einen Rahmen RAH, eingeleitet wird.Two fiber elements or tension elements FE1, FE2 are used as torque supports, through which the differential torque of the drive and output is introduced into a support structure, here for example into a frame RAH.

Die beiden Faserelemente bzw.

Dies wird durch die Wahl der Position der Anschlusspunkte AP1G, AP1M, AP2G, AP2R erreicht.This is achieved by choosing the position of the connection points AP1G, AP1M, AP2G, AP2R.

Die Anschlusspunkte AP1G, AP1M des ersten Faserelements FE1 sind derart gewählt, dass das erste Faserelement FE1 ein erstes Differenzdrehmoment bzw. eine daraus resultierende erste Zugkraft einer ersten Rotationsrichtung des Motors MOT über den Motor MOT und über dessen Befestigungspunkte BEF1, BEF2 an den Rahmen RAH überträgt.The connection points AP1G, AP1M of the first fiber element FE1 are selected such that the first fiber element FE1 transmits a first differential torque or a resulting first tensile force of a first rotation direction of the motor MOT via the motor MOT and via its attachment points BEF1, BEF2 to the frame RAH .

Die Anschlusspunkte AP2G, AP2R des zweiten Faserelements FE2 sind derart gewählt, dass das zweite Faserelement FE2 ein zweites Differenzdrehmoment bzw. eine daraus resultierende zweite Zugkraft einer zweiten Rotationsrichtung des Motors MOT direkt an den Rahmen RAH überträgt.The connection points AP2G, AP2R of the second fiber element FE2 are selected such that the second fiber element FE2 transmits a second differential torque or a resulting second tensile force of a second direction of rotation of the motor MOT directly to the frame RAH.

Die beiden Faserelemente FE1, FE2 bestehen aus Faserwerkstoffen, die bevorzugt Kevlar-Fasern und/oder Carbon-Fasern beinhalten bzw. die vollständig aus Kevlar-Fasern und/oder Carbon-Fasern aufgebaut sind.The two fiber elements FE1, FE2 consist of fiber materials which preferably contain Kevlar fibers and/or carbon fibers or which are constructed entirely from Kevlar fibers and/or carbon fibers.

Die beiden Faserelemente FE1, FE2 übertragen somit ausschließlich Zugkräfte.The two fiber elements FE1, FE2 therefore only transmit tensile forces.
