Abstract

A running gear for drop-frame rail vehicles includes a running-gear frame on which individual wheels are each rotatably mounted through a respective rocker and the rocker is fastened in an articulated manner and supported through primary springs. The connection of the running-gear frame to the carriage body of the drop-frame rail vehicle is provided through two articulated rods which are mounted on a crossmember of the running gear frame and which are fastened to the carriage body. The carriage body is supported on the running-gear frame through secondary springs which are mounted in pockets of the transverse ends of the crossmembers. Transverse stops which are disposed in the crossmember limit the transverse movement of the carriage body in relation to the running gear. Advantageously, the individual wheel and the drive of the individual wheel are mounted in the rocker in such a manner as to be connected to form a structural unit. This structure provides running gears for drop-frame rail vehicles in which the drop-frame nature of the carriage body is completely preserved and only wheel cases are present in the region of the individual wheels of the running gear.

Description

Die Erfindung betrifft ein Fahrwerk für Niederflurbahnen mit einem Fahrwerkrahmen, an dem Einzelräder über je eine Schwinge drehbar gelagert sind und die Schwinge gelenkig und sich über Primärfedern abstützend befestigt ist.The invention relates to a chassis for low-floor railways with a chassis frame, on which individual wheels are rotatably mounted via a rocker each and the rocker is articulated and is supported by primary springs.

Durch die EP 03 84 512 ist ein derartiges Fahrwerk bekannt. Der Rahmen des Fahrwerks ist dabei etwa H-förmig mit Doppelquerträger ausgebildet. Die Doppelquerträger sind an ihren Querenden durch Außenlangträger miteinander verbunden, die geringfügig die Doppelquerträger in Fahrwerklängsrichtung überragen. Zwischen dem Doppelquerträger ist ein vertikal und horizontal quer beweglicher Wiegenquerträger angeordnet. Dieser Wiegenquerträger ist an seinen Querenden über Pendel in Sekundärfedern aufgehängt, die auf den Außenlangträgern des Fahrwerks abgestützt sind. Der Wiegenquerträger trägt mittig eine Aufnahme für den Drehzapfen des Wagenkastens. Beidseitig der Aufnahme für den Drehzapfen sind in Fahrwerkquerrichtung auf dem Wiegenquerträger Gegenlager vorgesehen, über die sich der Wagenkasten bei Kurvenfahrt abstützt. Die Außenlangträger des Fahrwerkrahmens tragen nahe ihren Längsenden an Schwingen Einzelräder, wobei die Schwingen an den Außenlangträgern gelenkig gelagert sind und die Schwingen sich über Primärfedern gegeneinander und am Fahrwerkrahmen abstützen.Such a chassis is known from EP 03 84 512. The frame of the undercarriage is approximately H-shaped with a double cross member. The double cross members are connected to one another at their cross ends by outer longitudinal members, which project slightly beyond the double cross members in the longitudinal direction of the chassis. A vertically and horizontally transversely movable cradle cross member is arranged between the double cross member. This cradle cross member is suspended at its cross ends via pendulums in secondary springs, which are supported on the outer side members of the chassis. The cradle crossmember has a center mount for the trolley body pivot. Counter bearings are provided on both sides of the receptacle for the trunnion in the transverse direction of the chassis, via which the car body is supported when cornering. The outer longitudinal members of the undercarriage frame carry individual wheels near their longitudinal ends on the rockers, the rockers being articulated on the outer longitudinal members and the rockers being supported against one another and on the undercarriage frame via primary springs.

Nachteilig bei dieser vorgenannten Ausführung ist die Anordnung eines Wiegenquerträgers und dessen Aufhängung an den Sekundärfedern, die zum einen eine aufwendige Bauweise darstellt und zum anderen im Bereich zwischen den Einzelrädern einer Fahrwerklängsseite eine so große Bauhöhe erfordert, daß die Niederflurigkeit der Niederflurbahn zumindest in diesem Bereich erheblich beeinträchtigt wird und Quersitze nicht angeordnet werden können. Ein weiterer Nachteil dieser vorbekannten Konstruktion besteht darin, daß durch die Führung des Fahrwerks am Wagenkasten mittels eines Drehzapfens für die Anwendung bei Niederflurbannen zusätzliche Schlingerdämpfer erforderlich sind, die die Wirtschaftlichkeit des Fahrwerks mindern.The disadvantage of this aforementioned embodiment is the arrangement of a cradle cross member and its suspension on the secondary springs, which on the one hand represents a complex construction and on the other hand requires such a large height in the area between the individual wheels of a chassis longitudinal side that the low-floor nature of the low-floor railway at least in this Area is significantly affected and cross seats can not be arranged. Another disadvantage of this previously known construction is that additional anti-roll dampers are required by guiding the chassis on the car body by means of a pivot for use in low-floor vehicles, which reduce the economy of the chassis.

Fahrwerke mit Einzelrädern sind weiter aus der EP 01 29 772 bekannt. Bei diesem Fahrwerk sind die Einzelräder ebenfalls über Schwingen am Rahmen des Fahrwerks gelagert. Das Fahrwerk dieser Vorveröffentlichung baut jedoch zumindest im Bereich zwischen den Rädern einer Laufwerklängsseite so hoch, daß es für Niederflurbahnen mit durchgängigem Wagenboden nicht anwendbar ist. Einzelräder für Fahrwerke für den Bahnverkehr sind weiter aus der DE-OS 35 38 513 für sich bekannt. Bei dieser Vorveröffentlichung sind die Einzelräder über Schwingen am Wagenkasten aufgehängt.Undercarriages with individual wheels are also known from EP 01 29 772. With this undercarriage, the individual wheels are also mounted on the frame of the undercarriage via rockers. However, the undercarriage of this prior publication builds so high, at least in the area between the wheels of a long drive side, that it cannot be used for low-floor railways with a continuous carriage floor. Single wheels for trolleys for rail traffic are further known from DE-OS 35 38 513. In this prior publication, the individual wheels are suspended from the body by means of rockers.

Aus der Praxis sind weiter Schwingen für die Anlenkung von Radachsen für den Bahnverkehr bekannt, bei denen die Schwingen über Federn am Drehgestellrahmen abgestützt sind.In practice, swingarms for the articulation of wheel axles for rail traffic are also known, in which the swingarms are supported by springs on the bogie frame.

Vorliegender Erfindung lag die Aufgabe zugrunde, Fahrwerke für Niederflurbahnen zu schaffen, bei denen die Niederflurigkeit des Wagenkastens vollständig erhalten bleibt und wobei lediglich Radkästen im Bereich der Räder des Fahrwerks vorhanden sind, die in den Wagenkasten ragen und die so unter Sitzen angeordnet werden, daß der Wagenboden durchgängig ausgebildet werden kann.The present invention was based on the object of creating undercarriages for low-floor railways in which the low-flooring of the car body is completely retained and only wheel arches are present in the area of the wheels of the undercarriage which protrude into the car body and which are arranged under seats so that the Carriage floor can be formed consistently.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Anbindung des Fahrwerkrahmens am Wagenkasten der Niederflurbahn über zwei mit Abstand zueinander an einem Querträger des Fahrwerkrahmens gelenkig gelagerte Anlenkstangen erfolgt, die andererseits ebenfalls gelenkig am Wagenkasten befestigt sind, daß der Wagenkasten über Sekundärfedern auf dem Fahrwerkrahmen abgestützt ist, die in Taschen der Querenden der Querträger gelagert sind und daß im Querträger mit Abstand zueinander angeordnete Queranschläge die Querbewegung des Wagenkastens gegenüber dem Fahrwerk begrenzen. Hierbei ist die in Form eines Winkelhebels ausgebildete Schwinge doppelarmig ausgebildet, wobei ein Ende der Schwinge beidseitig kurze, in Fahrwerklängsrichtung weisende Konsolen an den Querenden des Querträgers des Drehgestellrahmens umgreift und dort gelenkig gelagert ist, das mittlere Ende der Schwinge beidseitig das Einzelrad umgreift und dessen Achse trägt und am dritten Ende der Schwinge deren beide Arme miteinander verbunden sind und gegen die Primärfeder anliegen. Auf dem Querträger des Fahrwerks ist für jede Schwinge ein Konsol angeordnet, das das Gegenlager für die Primärfeder bildet. Durch diese Ausbildung des Fahrwerks wird sowohl der Bereich zwischen den Einzelrädern in Fahrwerkquerrichtung als auch der Bereich zwischen den Einzelrädern einer Fahrwerklängsseite von hochbauenden Elemente freigehalten. Der Wagenkasten der Niederflurbahn kann somit bis auf die Radkästen durchgängig und ohne störende Abstufungen ausgebildet werden.This object is achieved according to the invention in that the connection of the undercarriage frame to the car body of the low-floor railway takes place via two articulated connecting rods which are articulated at a distance from one another on a cross member of the undercarriage frame and which are also articulatedly attached to the car body in that the car body is attached to the undercarriage frame by means of secondary springs is supported, which are mounted in pockets of the cross ends of the cross member and that in the cross member spaced transverse stops limit the transverse movement of the car body relative to the chassis. Here is the one in the form of an angle lever Swing arm designed double-armed, one end of the swing arm engaging on both sides of short brackets pointing in the longitudinal direction of the chassis at the transverse ends of the crossbeam of the bogie frame and being articulated there, the middle end of the swing arm engaging around the single wheel on both sides and supporting its axle and at the third end of the swing arm both arms are connected to each other and bear against the primary spring. For each rocker arm, a bracket is arranged on the crossmember of the undercarriage, which forms the counter bearing for the primary spring. This design of the undercarriage keeps both the area between the individual wheels in the transverse direction of the undercarriage and the area between the individual wheels of a longitudinal side of the undercarriage free of high-rise elements. The wagon body of the low-floor railway can thus be designed consistently and without annoying gradations except for the wheel wells.

Vorteilhaft sind das Einzelrad und der Antrieb des Einzelrades zu einer Baueinheit verbunden in der Schwinge gelagert. Hierbei ist ebenfalls an der Schwinge die Bremse des Einzelrades gelagert und als Klotz- oder Scheibenbremse auf das Gehäuse des Antriebs wirkend ausgebildet. Durch diese Ausbildung des Einzelrades und dessen Antriebs zu einer Baueinheit, die gleichzeitig als Gegenlager für die Bremse verwendet werden kann, werden ebenfalls hochbauende und damit die Niederflurigkeit des Wagenkastens störende Bauteile vermieden.The single wheel and the drive of the single wheel are advantageously connected to form a structural unit in the rocker arm. Here, too, the brake of the single wheel is mounted on the rocker and is designed to act as a block or disc brake on the housing of the drive. This design of the single wheel and its drive to form a structural unit that can also be used as a counter bearing for the brake also avoids high-rise components that thus disrupt the low-floor structure of the car body.

Vorteilhaft sind die Anlenkstangen des Fahrwerks sphärisch gelagert. Durch diese sphärische Lagerung können die durch die Queranschläge begrenzten Querbewegungen des Wagenkastens gegenüber dem Fahrwerk störungsfrei in das Fahrwerk übergeleitet werden.The linkage rods of the undercarriage are advantageously spherically mounted. As a result of this spherical mounting, the transverse movements of the car body with respect to the undercarriage limited by the transverse stops can be transferred into the undercarriage without interference.

Der Rahmen des erfindungsgemäßen Fahrwerks besteht im wesentlichen aus dem Querträger 1. Der Querträger 1 kann dabei, wie in der Zeichnung dargestellt, als Monoträger oder gemäß einem nicht dargestellten Ausführungsbeispiel als Doppelquerträger ausgebildet sein. An den Querenden des Querträgers 1 sind kurze, in Fahrzeuglängsrichtung weisende Konsolen 2 angeordnet. Querträger 1 und Konsolen 2 sind in Kastenbauweise flachbauend ausgebildet. Jedes Konsol 2 trägt an seinem freien Ende je eine Schwinge 3. Diese Schwinge 3 ist in Form eines Winkelhebels und doppelarmig ausgebildet. Ein Ende der Schwinge 3 umgreift beidseitig das Konsol 2 und ist an diesem über ein Gelenk 4 gelenkig gelagert. Das mittlere Ende der Schwinge 3 umgreift beidseitig ein Einzelrad 5, dessen Achse 6 in der Schwinge befestigt ist. Gemäß einem Alternativausführungsbeispiel kann die Achse 6 drehbar in der Schwinge 3 gelagert sein. Am dritten Ende der Schwinge 3 sind deren beiden Arme miteinander verbunden und stützen sich gegen eine Primärfeder 7 ab, die an einem auf der Oberseite des Querträgers 1 angeordneten Konsol 8 befestigt ist. Das Konsol 8 ist dabei in seiner horizontalen Erstreckung so konzipiert, daß die Projektionsfläche der Primärfeder 7 nur geringfügig überschritten wird.The frame of the undercarriage according to the invention essentially consists of the cross member 1. The cross member 1 can, as shown in the drawing, be designed as a mono member or, according to an exemplary embodiment not shown, as a double cross member. Short brackets 2 pointing in the longitudinal direction of the vehicle are arranged at the transverse ends of the cross member 1. Cross member 1 and brackets 2 are constructed in a box construction flat. Each bracket 2 carries a rocker 3 at its free end. This rocker 3 is designed in the form of an angle lever and has two arms. One end of the rocker arm 3 engages around the bracket 2 on both sides and is articulated thereon via a joint 4. The middle end of the rocker 3 encompasses a single wheel 5 on both sides, the axis 6 of which is fastened in the rocker. According to an alternative embodiment, the axis 6 can be rotatably mounted in the rocker 3. At the third end of the rocker 3, its two arms are connected to one another and are supported against a primary spring 7, which is fastened to a bracket 8 arranged on the top of the cross member 1. The bracket 8 is designed in its horizontal extent so that the projection surface of the primary spring 7 is exceeded only slightly.

In Fahrwerkquermitte sind außen an den Querträgern 1 Taschen 9 angeordnet, die die als Luft- oder Schraubenfeder ausgebildete Sekundärfeder 10 aufnehmen.In the middle of the undercarriage, 1 pockets 9 are arranged on the outside of the crossbeams and hold the secondary spring 10, which is designed as an air or coil spring.

Der nicht dargestellte Wagenkasten, der im Bereich des Fahrwerks aus einem kurzen, gelenkig mit Fahrgastmodulen verbundenen Fahrwerkmodul besteht, ist vertikal auf den Sekundärfedern des Fahrwerks abgestützt. An dem Querträger 1 des Rahmens des Fahrwerks sind mit Abstand zueinander gelenkig Anlenkstangen 11 befestigt, die mit ihrem anderen Ende ebenfalls gelenkig am Wagenkasten angelenkt sind. Die Lager 12 der Anlenkstangen 11 sind dabei sphärisch ausgebildet. In Fahrwerkquermitte sind weiter mit Abstand zueinander im Querträger 1 Queranschläge 13 vorgesehen. Diese Queranschläge 13 wirken mit entsprechenden Gegenlagern des Wagenkastens zusammen und begrenzen den Querausschlag des Wagenkastens gegenüber dem Fahrwerk. Einseitig am Querträger 1 des Rahmens des Fahrwerks und andererseits am Wagenkasten befestigte Stoßdämpfer 14 dienen der Verbesserung des Laufverhaltens.The car body, not shown, which in the area of the undercarriage consists of a short undercarriage module articulated to passenger modules, is supported vertically on the secondary springs of the undercarriage. On the cross member 1 of the frame of the chassis articulated rods 11 are attached at a distance from each other, which are also articulated at their other end to the car body. The bearings 12 of the link rods 11 are spherical. In the middle of the undercarriage 1 cross stops 13 are further provided at a distance from each other in the cross member. These cross stops 13 interact with corresponding counter bearings of the car body and limit the transverse deflection of the car body relative to the chassis. Shock absorbers 14 fastened on one side to the cross member 1 of the chassis frame and on the other hand serve to improve the running behavior.

In dem in der Zeichnung dargestellten Ausführungsbeispiel der Erfindung lagert das Einzelrad 5 drehbar auf der Achse 6 der Schwinge 3. Das Einzelrad 5 ist dabei mit seinem Antrieb 16 zu einer Baueinheit verbunden und drehbar auf der Achse 6 der Schwinge 3 gelagert. Der Antrieb 16 kann dabei erfindungsgemäß aus einem Direktantrieb oder einem Motor mit nachgeschaltetem Getriebe bestehen. An der Schwinge 3 ist weiter das in dem Ausführungsbeispiel als Scheibenbremse ausgebildete Bremsgestänge 17 mit Bremszylinder 18 gelagert. Die Bremse 17, 18 wirkt dabei direkt auf das entsprechend ausgebildete Gehäuse des Antriebs 16. Gemäß einem anderen, nicht dargestellten Ausführungsbeispiel der Erfindung kann die Bremse 17, 18 auch als Klotzbremse auf den Mantel des Antriebs 16 oder das Einzelrad 5 wirkend, ausgebildet sein.In the exemplary embodiment of the invention shown in the drawing, the individual wheel 5 is rotatably supported on the axis 6 of the rocker 3. The individual wheel 5 is connected with its drive 16 to form a structural unit and is rotatably mounted on the axis 6 of the rocker 3. According to the invention, the drive 16 can consist of a direct drive or a motor with a downstream transmission. On the rocker 3, the brake linkage 17 with brake cylinder 18, which is designed as a disc brake in the exemplary embodiment, is also mounted. The brake 17, 18 acts directly on the correspondingly designed housing of the drive 16. According to another exemplary embodiment of the invention, not shown, the brake 17, 18 can also be designed as a block brake acting on the casing of the drive 16 or the single wheel 5.

Wie aus der Zeichnung ersichtlich, ist das erfindungsgemäße Fahrwerk vertikal gegen Federkraft beweglich, horizontal jedoch nahezu starr und drehfest an dem Wagenkasten angebunden. Die vorbeschriebene Anbindung gewährleistet einen schlingerfreien Lauf einer aus mehreren Fahrwerk- und Fahrgastmodulen bestehenden Niederflurbahn.As can be seen from the drawing, the undercarriage according to the invention is vertically movable against spring force, but horizontally almost rigidly and non-rotatably connected to the car body. The connection described above ensures that a low-floor train consisting of several running gear and passenger modules runs smoothly.
