Description

Die Erfindung betrifft Drehgestelle für Schienenfahrzeuge mit mindestens zwei in Achslagern gelagerten Radsätzen und wenigstens einem Querträger.The invention relates to bogies for rail vehicles with at least two wheel sets mounted in axle bearings and at least one cross member.

Solche Drehgestelle sind z.B. aus der US 3 948 188 A1 bekannt.Such bogies are for example from the U.S. 3,948,188 A1 known.

Konventionelle Drehgestelle für Schienenfahrzeuge in Stahlbauweise, bei denen die Primärfederung zumeist durch Blattfedern, Schraubenfedern oder Gummi-Metall-Federn aufgebracht wird, weisen neben dem hohen Eigengewicht zusätzliche Nachteile dadurch auf, dass sie aus vielen Einzelteilen bestehen und wenig Bauraum für Einbauten wie Antriebe, Steuergeräte und Bremsen vorhanden ist.Conventional bogies for rail vehicles in steel construction, in which the primary suspension is mostly applied by leaf springs, helical springs or rubber-metal springs, have additional disadvantages in addition to their high dead weight in that they consist of many individual parts and little space for built-in components such as drives and control units and braking is available.

Um das Eigengewicht zu verringern, sind aus dem Stand der Technik Drehgestelle in Faserverbundbauweise bekannt, bei denen die Primärfederung durch den Drehgestellrahmen oder durch Blattfedern in Faserverbundbauweise realisiert wird.In order to reduce the dead weight, bogies in fiber composite construction are known from the prior art, in which the primary suspension is implemented by the bogie frame or by leaf springs in fiber composite construction.

In der DE 29 52 182 A1 ist ein Drehgestell offenbart, bei dem der Drehgestellrahmen aus einem federnd elastischen faserverstärkten Werkstoff aufgebaut ist und die Aufgabe der Primärfederung übernimmt.In the DE 29 52 182 A1 a bogie is disclosed in which the bogie frame is constructed from a resiliently elastic fiber-reinforced material and takes over the task of primary suspension.

Beispielsweise aus der US 2012/0279416 bekannt sind Drehgestelle, deren Primärfederung durch separate Blattfedern in Faserverbundbauweise aufgebracht wird. Schwierig gestaltet sich hier insbesondere die Anbindung der federnden Elemente an die übrigen Bestandteile des Drehgestellrahmens.For example from the US 2012/0279416 Bogies are known whose primary suspension is applied by separate leaf springs in fiber composite construction. The connection of the resilient elements to the other components of the bogie frame is particularly difficult here.

Die DE 36 12 797 A1 offenbart ein Drehgestell, bei dem die Primärfederung durch Längsträger eines doppel-H-förmigen Drehgestellrahmens, die in Faserverbundbauweise ausgeführt sind, aufgebracht wird. Als Rahmenversteifungselement weist das Drehgestell zusätzlich eine torsionselastische Platte auf, die die Längsträger miteinander verbindet. Nachteilig weisen die torsionselastische Platte und insbesondere die Längsträger eine komplizierte Faserverbundstruktur auf, da sich z. B. das Elastizitätsverhalten der Längsträger in Längsrichtung senkrecht zur Drehgestellebene in definierter Weise ändern muss, um die Federeigenschaften zu erfüllen.The DE 36 12 797 A1 discloses a bogie in which the primary suspension is applied by longitudinal members of a double-H-shaped bogie frame, which are made in fiber composite construction. As a frame stiffening element, the bogie also has a torsion-elastic plate that connects the side members to one another. Disadvantageously, the torsionally elastic plate and in particular the side members have a complicated fiber composite structure, since z. B. must change the elasticity behavior of the side members in the longitudinal direction perpendicular to the bogie plane in a defined manner in order to meet the spring properties.

Drehstabfederungen sind aus dem Kraftfahrzeug- sowie aus dem Kettenfahrzeugbereich bekannt, z. B. aus der DE 920 291 und der US 4,194,761 . Des Weiteren werden Torsionsstäbe als Stabilisatoren in Laufwerken verwendet und sind dort üblicherweise als mehrfach gebogene Stangen, die die Radaufhängungen der Räder einer Achse und die Laufwerksstruktur miteinander verbinden, ausgeführt. Stabilisatoren dienen zur Reduzierung des Wankwinkels eines Wagenkastens.Torsion bar suspensions are known from the motor vehicle sector as well as from the tracked vehicle sector, e.g. B. from the DE 920 291 and the U.S. 4,194,761 . Furthermore, torsion bars are called Stabilizers are used in running gears and are usually designed as multi-bent rods that connect the wheel suspensions of the wheels of an axle and the running gear structure to one another. Stabilizers are used to reduce the roll angle of a car body.

Der im Patentanspruch 1 angegebenen Erfindung liegt die Aufgabe zugrunde, eine alternative Gestaltungsvariante für ein Drehgestell eines Schienenfahrzeugs so zu schaffen, dass diese in Leichtbauweise ausführbar und kostengünstig fertigbar sind.The invention specified in claim 1 is based on the object of creating an alternative design variant for a bogie of a rail vehicle in such a way that it can be implemented in a lightweight design and manufactured at low cost.

Diese Aufgabe wird mit den im Patentanspruch 1 aufgeführten Merkmalen gelöst.This object is achieved with the features listed in claim 1.

Die Drehgestelle als Bestandteile von Schienenfahrzeugen mit mindestens zwei in Achslagern gelagerten Radsätzen und wenigstens einem Querträger zeichnen sich insbesondere dadurch aus, dass diese in Leichtbauweise ausführbar und kostengünstig fertigbar sind.The bogies as components of rail vehicles with at least two wheel sets mounted in axle bearings and at least one cross member are characterized in particular by the fact that they can be made in a lightweight construction and can be manufactured at low cost.

Dazu sind die Achslager eines Radsatzes über zwei Achshebel mit dem Querträger gelenkig verbunden, so dass die Achshebel mit den Achslagern und der Querträger eine H-Form ausbilden. Der Querträger weist mindestens zwei parallel zu den Achsen der Radsätze angeordnete Torsionsstäbe auf, die mit dem Querträger fest verbunden sind. Weiterhin weisen die Torsionsstäbe Federhebel auf, so dass der nicht mit dem Torsionsstab verbundene Endenbereich des Federhebels auf das Achslager wirkt.For this purpose, the axle bearings of a wheel set are articulated to the cross member via two axle levers, so that the axle levers with the axle bearings and the cross member form an H shape. The cross member has at least two torsion bars which are arranged parallel to the axes of the wheel sets and which are firmly connected to the cross member. Furthermore, the torsion bars have spring levers, so that the end area of the spring lever that is not connected to the torsion bar acts on the axle bearing.

Das Drehgestell eines Schienenfahrzeugs weist mindestens zwei Radsätze auf, von denen jeder Radsatz zwei mit einer Achse verbundene Räder umfasst. Der Radsatz ist in Achslagern gelagert, die weiterhin über die Achshebel gelenkig mit dem Querträger verbunden sind. Auf die Achslager des Radsatzes wirken bei dem erfindungsgemäß ausgebildeten Drehgestell zwei mit dem Torsionsstab verbundene Federhebel, so dass vorteilhafterweise die Primärfederung zumindest teilweise durch die auf die Achslager wirkenden Torsionsstäbe übernommen wird. Durch diese Torsionsstäbe als gerade Torsionsfedern beruht damit die Primärfederung auf einer rotatorischen Federbewegung anstatt auf einer bekannten translatorischen Federbewegung.The bogie of a rail vehicle has at least two sets of wheels, each set of wheels comprising two wheels connected to an axle. The wheel set is stored in axle bearings, which are still articulated to the cross member via the axle levers. In the bogie designed according to the invention, two spring levers connected to the torsion bar act on the axle bearings of the wheelset, so that the primary suspension is advantageously at least partially taken over by the torsion bars acting on the axle bearings. As a result of these torsion bars as straight torsion springs, the primary suspension is based on a rotary spring movement instead of a known translational spring movement.

Die Geometrie und das Material der Torsionsstäbe können definiert an die zu erwartenden Lasten angepasst werden.The geometry and the material of the torsion bars can be adapted to the expected loads.

Dadurch, dass sich die Achslager in den gelenkig mit dem Querträger verbundenen Achshebeln befinden, ist der Querträger und damit der damit verbundene Wagenkasten federnd angeordnet. Damit können die gelenkig angeordneten Achshebel auch einen Beitrag zur Sekundärfederung des Schienenfahrzeugs liefern.Because the axle bearings are located in the axle levers articulated to the cross member, the cross member and thus the car body connected to it are resiliently arranged. The articulated axle levers can thus also make a contribution to the secondary suspension of the rail vehicle.

Vorteilhaft umfasst das vorgeschlagene Drehgestell geometrisch wenig komplexe Einzelstrukturen, die wenigstens zum Teil kostengünstig auch in einer Leichtbauweise umgesetzt werden können.Advantageously, the proposed bogie comprises individual structures that are geometrically less complex, at least some of which can also be implemented cost-effectively in a lightweight construction.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Patentansprüchen 2 bis 10 angegeben.Advantageous embodiments of the invention are given in claims 2 to 10.

In einer Weiterbildung der Erfindung gemäß Patentanspruch 2 sind in axialer Richtung zwei Torsionsstäbe nacheinander am Querträger angeordnet. Die zueinander weisenden Enden der Torsionsstäbe sind mit deren Endenbereichen mit dem Querträger verbunden. Weiterhin wiesen die anderen Enden der Torsionsstäbe einen Federhebel auf.In a further development of the invention according to claim 2, two torsion bars are arranged one after the other on the cross member in the axial direction. The ends of the torsion bars facing each other are connected to the cross member by their end regions. Furthermore, the other ends of the torsion bars had a spring lever.

Der Querträger besitzt nach der Weiterbildung des Patentanspruchs 3 eine H-Form. Die Endenbereiche eines Torsionsstabs durchdringen lose die sich gegenüberliegenden Schenkel des H-förmigen Querträgers. Dazu können die Schenkel des Querträgers als Führungen oder Radiallager für den Torsionsstab ausgebildet sein. Der mittlere Bereich des Torsionsstabs ist mit dem H-förmigen Querträger fest verbunden. Weiterhin ist jeweils ein Achshebel mit einem Ende des Schenkels des Querträgers gelenkig verbunden, so dass das Achshebelgelenk ein Bestandteil des Querträgers ist. Die Achshebel verlängern somit die Schenkel des H-förmigen Querträgers.According to the development of claim 3, the cross member has an H shape. The end regions of a torsion bar loosely penetrate the opposing legs of the H-shaped cross member. For this purpose, the legs of the cross member can be designed as guides or radial bearings for the torsion bar. The middle area of the torsion bar is firmly connected to the H-shaped cross member. Furthermore, an axle lever is connected in an articulated manner to one end of the leg of the cross member, so that the axle lever joint is a component of the cross member. The axle levers thus extend the legs of the H-shaped cross member.

Ein Endenbereich eines Torsionsstabs befindet sich nach der Weiterbildung des Patentanspruchs 4 als bewegbarer Teil an oder in wenigstens einem, mit dem Querträger verbundenen Radiallager. Der Endenbereich des Torsionsstabs durchdringt das Radiallager und das Ende des Torsionsstabs besitzt nach dem Radiallager den Federhebel. Die Radiallager für einen Torsionsstab oder zwei nacheinander angeordnete Torsionsstäbe können sich damit zwischen den Achshebeln oder im Bereich der Achshebel befinden. Damit können die Federhebel gegenüber den, die Radsätze tragenden und führenden Schienen, über den Achshebeln angeordnet sein. Dabei können die Endenbereiche der Federhebel auf die Endenbereiche der Achshebel mit den Achslagern wirken.According to the development of claim 4, one end region of a torsion bar is located as a movable part on or in at least one radial bearing connected to the cross member. The end area of the torsion bar penetrates the radial bearing and the end of the torsion bar has the spring lever after the radial bearing. The radial bearings for a torsion bar or two torsion bars arranged one after the other can thus be located between the axle levers or in the area of the axle levers. The spring levers can thus be arranged above the axle levers opposite the rails carrying and guiding the wheel sets. The end areas of the spring levers can act on the end areas of the axle levers with the axle bearings.

Der Torsionsstab besitzt nach der Weiterbildung des Patentanspruchs 5 im Querschnitt die Form eines Kegelschnitts und/oder eines Mehrecks. Der Torsionsstab kann damit auch über seine Länge Profilierungen aufweisen. Damit kann eine optimale Anbindung und Lasteinleitung des Federhebels zum Querträger erfolgen. Eine Profilierung über die freie Länge der Torsionsstäbe kann des Weiteren zur Optimierung der mechanischen Eigenschaften im dynamischen Betrieb vorhanden sein.According to the development of claim 5, the torsion bar has the shape of a conic section and / or a polygon in cross section. The torsion bar can thus also have profiles over its length. This enables optimal connection and load transfer of the spring lever to the cross member. Profiling over the free length of the torsion bars can also be used to optimize the mechanical properties in dynamic operation.

Die Torsionsstäbe und/oder die Federhebel sind nach der Weiterbildung des Patentanspruchs 6 aus einem Metall oder einem Faserverbundwerkstoff oder in Mischbauweise ausgeführt. Aufgrund des geringen Gewichts ist die Ausführung in Faserverbundbauweise besonders vorteilhaft. Dabei können insbesondere Glasfasern oder Kohlenstofffasern oder Aramidfasern zum Einsatz kommen.According to the development of claim 6, the torsion bars and / or the spring levers are made from a metal or a fiber composite material or in a mixed construction. Due to the low weight, the fiber composite design is particularly advantageous. In particular, glass fibers or carbon fibers or aramid fibers can be used.

Zwischen den Endenbereichen des Achshebels und des Federhebels befindet sich nach der Weiterbildung des Patentanspruchs 7 vorteilhafterweise wenigstens ein Dämpfungskörper. Die Dämpfungskörper des Drehgestells sind weitere Federelemente der Primärfederung und der Sekundärfederung.According to the development of claim 7, at least one damping body is advantageously located between the end regions of the axle lever and the spring lever. The damping bodies of the bogie are further spring elements of the primary suspension and the secondary suspension.

Der Dämpfungskörper besteht nach der Weiterbildung des Patentanspruchs 8 aus einem Elastomer. Das kann insbesondere ein Gummi sein.According to the development of claim 8, the damping body consists of an elastomer. This can in particular be a rubber.

Der Querträger ist nach der Weiterbildung des Patentanspruchs 9 ein Grundkörper mit den Gliedern für die Drehgelenke der Achshebel und mit Befestigungselementen für Anbauteile. Der Grundkörper besteht aus einem Metall und/oder einem Faserverbundwerkstoff. Anbauteile können dabei insbesondere Bremsvorrichtungen und/oder Antriebe sein.According to the development of claim 9, the cross member is a base body with the links for the swivel joints of the axle levers and with fastening elements for add-on parts. The base body consists of a metal and / or a fiber composite material. Add-on parts can in particular be braking devices and / or drives.

Der Querträger ist nach der Weiterbildung des Patentanspruchs 10 ein Balken oder ein Rahmen.According to the development of claim 10, the cross member is a beam or a frame.

Das Drehgestell weist nach der Weiterbildung des Patentanspruchs 11 weitere Federelemente zur Sekundärfederung und eine Drehpfanne auf. Die weiteren Federelemente übernehmen die Aufgabe der Sekundärfederung des Wagenkastens. Insbesondere können dazu Luftfedern vorgesehen sein, die am Querträger angeordnet sind.According to the development of claim 11, the bogie has further spring elements for secondary suspension and a rotating pan. The other spring elements take on the task of the secondary suspension of the car body. In particular, air springs can be provided for this purpose, which are arranged on the cross member.

Fig. 2 zeigt das Drehgestell aus Fig. 1 in einer prinzipiellen Draufsicht. Fig. 2 shows the bogie Fig. 1 in a principle top view.

Der Querträger 1 weist die mindestens zwei parallel zu den Achsen 8 der Radsätze 3 angeordnete Torsionsstäbe 5 auf. Der jeweilige Mittelbereich der Torsionsstäbe 5 ist mit dem Querträger 1 verbunden. Das Ende des Torsionsstabs 5 besitzt den Federhebel 6, wobei das Ende des Federhebels 6 auf das Achslager 4 wirkt. Damit sind die Torsionsstäbe 5 und die Federhebel 6 die Primärfederung oder ein Teil der Primärfederung des Drehgestells.The cross member 1 has the at least two torsion bars 5 arranged parallel to the axes 8 of the wheel sets 3. The respective central area of the torsion bars 5 is connected to the cross member 1. The end of the torsion bar 5 has the spring lever 6, the end of the spring lever 6 acting on the axle bearing 4. The torsion bars 5 and the spring levers 6 are thus the primary suspension or part of the primary suspension of the bogie.

Fig. 3 zeigt das Drehgestell aus Fig. 1 in einer prinzipiellen Seitenansicht. Fig. 3 shows the bogie Fig. 1 in a basic side view.

Der Endenbereich des Torsionsstabs 5 durchdringt den Schenkel des H-förmigen Querträgers 1. Dazu besitzt dieser eine Öffnung 10. Dabei kann der Torsionsstab 5 im Querträger 1 gelagert sein. Die Achshebelgelenke 9 sind Bestandteile des H-förmigen Querträgers 1, wobei die Achshebel 2 die Schenkel des H-förmigen Querträgers 1 verlängern.The end area of the torsion bar 5 penetrates the leg of the H-shaped cross member 1. For this purpose, it has an opening 10. The torsion bar 5 can be supported in the cross member 1. The axle lever joints 9 are components of the H-shaped cross member 1, the axle levers 2 extending the legs of the H-shaped cross member 1.

Der Torsionsstab 5 ist im Querschnitt kreisförmig und/oder mehreckförmig ausgebildet. Dazu kann dieser über seine Länge Profilierungen besitzen. Die Torsionsstäbe 5 und die Federhebel 6 können vorteilhafterweise aus einem Faserverbundwerkstoff bestehen.The torsion bar 5 is circular and / or polygonal in cross section. This can have profiles along its length. The torsion bars 5 and the spring levers 6 can advantageously consist of a fiber composite material.

Der Mittelbereich des Torsionsstabs 5 kann sich drehfest in einer Buchse als Bestandteil des Querträgers 1 befinden. Dazu ist wenigstens dieser Mittelbereich und die Öffnung der Buchse im Querschnitt mehreckig ausgebildet. Die Endenbereiche des Torsionsstabs 5 durchdringen jeweils beidseitig die Öffnung 10 und weisen die Federhebel 6 auf. Dabei können der Torsionsstab 5 und die Federhebel 6 auch einstückig ausgebildet sein. Die Öffnungen 10 können jeweils eine Führung oder ein Radiallager für den jeweiligen Bereich des Torsionsstabs 5 sein.The central region of the torsion bar 5 can be located in a non-rotatable manner in a bushing as part of the cross member 1. For this purpose, at least this central area and the opening of the socket are polygonal in cross section. The end regions of the torsion bar 5 penetrate the opening 10 on both sides and have the spring levers 6. The torsion bar 5 and the spring lever 6 can also be designed in one piece. The openings 10 can each be a guide or a radial bearing for the respective area of the torsion bar 5.

Fig. 4 zeigt ein Drehgestell eines Schienenfahrzeugs mit innen liegenden Federhebeln 6 in einer perspektivischen prinzipiellen Ansicht. Fig. 4 shows a bogie of a rail vehicle with internal spring levers 6 in a perspective basic view.

In dieser alternativen Ausführungsform können die feststehenden Bestandteile der Führungen oder der Radiallager 11 auch mit dem Querträger 1 verbunden sein.In this alternative embodiment, the fixed components of the guides or the radial bearings 11 can also be connected to the cross member 1.

Fig. 5 zeigt das Drehgestell aus Fig. 4 in einer prinzipiellen Draufsicht. Fig. 5 shows the bogie Fig. 4 in a principle top view.

Die Führungen oder die Radiallager 11 können sich damit zwischen den Achshebeln 2 befinden.The guides or the radial bearings 11 can thus be located between the axle levers 2.

Fig. 6 zeigt das Drehgestell aus Fig. 4 in einer prinzipiellen Seitenansicht. Fig. 6 shows the bogie Fig. 4 in a basic side view.

Die Führungen oder die Radiallager 11 sind gegenüber den Schienen, die die Radsätze 3 aufnehmen und führen, beabstandet über den Achshebeln 2 angeordnet, so dass die Enden der Federhebel 6 damit auf die Endenbereiche der Achshebel 2 und damit auf die Achslager 4 wirken. Anstatt einer Führung oder eines Radiallagers 11 können auch beabstandet zueinander zwei Führungen oder zwei Radiallager angeordnet sein, so dass sich der Federhebel 6 zwischen diesen befinden kann.The guides or radial bearings 11 are spaced apart from the rails that accommodate and guide the wheel sets 3 above the axle levers 2 so that the ends of the spring levers 6 act on the end areas of the axle levers 2 and thus on the axle bearings 4. Instead of a guide or a radial bearing 11, two guides or two radial bearings can also be arranged at a distance from one another, so that the spring lever 6 can be located between them.

Zwischen den Endenbereichen des Achshebels 2 und des Federhebels 6 kann sich wenigstens ein Dämpfungskörper aus einem Elastomer befinden, der insbesondere aus Gummi bestehen kann.Between the end regions of the axle lever 2 and the spring lever 6 there can be at least one damping body made of an elastomer, which can in particular consist of rubber.

Der Querträger 1 stellt einen Grundkörper mit den Gliedern für die Achshebelgelenke 9 und mit Befestigungselementen für Anbauteile dar. Der Grundkörper kann dazu aus einem Metall und/oder einem Faserverbundwerkstoff und damit auch in einer Mischbauweise realisiert bestehen.The cross member 1 represents a base body with the links for the axle lever joints 9 and with fastening elements for attachments. For this purpose, the base body can consist of a metal and / or a fiber composite material and thus also be realized in a mixed construction.

Anbauteile können beispielsweise Luftfedern als Federelement und damit Bestandteile einer Sekundärfederung, Bremsvorrichtungen für die Räder 7 und Antriebe sein.Attachment parts can for example be air springs as a spring element and thus components of a secondary suspension, braking devices for the wheels 7 and drives.
