Abstract

In this bogie (1) the static and dynamic forces are absorbed by the frame (5). In designing the body unit fitted on the frame (5), therefore, only the unit's own weight and the passenger load are significant, thus facilitating the use of extremely lightly-built vehicle bodies. The bogie (1) consists of single-wheel drive units (2), a longeron (3) interconnecting them, on each long side of a drive (4), the frames (5) bearing the end unit (9) and a drive control (6) for turning the single-wheel drive units (2) horizontally depending on the curves. A wheelless central unit (10) is supported on each short side on the bogie (1) via a joint (8). A ush-pull device (7) engages with the short side opposite the joint (8). There are no lobbies inside the vehicle which is thus freely accessible. In the region of bogie there are recesses in the form of wheel-boxes in which certain parts of the bogie (1) are arranged.

Description

Die vorliegende Erfindung betrifft ein Fahrgestell für Niederflurwagen nach dem Wortlaut von Anspruch 1.The present invention relates to a chassis for low-floor wagons according to the wording of claim 1.

Aus der Offenlegungsschrift FR-A- 2 573 715 ist ein Fahrgestell bekannt, auf dem Wagenkasten mit abgesenkten Böden abgestützt werden. Je Rad ist eine eigene Achse vorgesehen. Die Achsen sind je Radsatz mit einer unterhalb des Radmittelpunktes liegenden Starrachse verbunden. Ein aus Längs- und Querträgern bestehender Fahrgestellrahmen liegt radinnenseitig auf den Achsen auf. In der Längsträgermitte ist eine Sekundärfederung zur Abstützung von zwei Wagenkästen angeordnet.From the published patent application FR-A-2 573 715 a chassis is known on which car bodies are supported with lowered floors. A separate axle is provided for each wheel. The axles are connected to a rigid axle below the wheel center for each wheel set. A chassis frame consisting of longitudinal and cross members rests on the axles on the inside of the wheel. A secondary suspension for supporting two car bodies is arranged in the middle of the longitudinal member.

Der Nachteil dieser bekannten Einrichtung liegt darin, dass trotz gekröpfter Radsatzachsen Podeste im Wageninnern unumgänglich sind. Die radinnenseitigen Achsen und der darauf abgestützte Fahrgestellrahmen vermindern die abgesenkte Bodenfläche und verlangen im Wageninnern Aussparungen in der Form von Podesten und Abstufungen. Im weiteren genügt die starre Anordnung der gekröpften Radsatzachsen den Anforderungen an moderne Fahrgstelle nicht mehr.The disadvantage of this known device is that, despite cranked axles, platforms in the interior of the car are unavoidable. The axles on the inside of the wheel and the chassis frame supported on them reduce the lowered floor area and require recesses in the form of pedestals and gradations inside the car. Furthermore, the rigid arrangement of the cranked axles no longer meets the requirements of modern chassis.

Aus der WO-A 85/05602 ist ein teilbares Laufdrehgestell im Gelenkbereich von Tramfahrzeugen in Niederflurbauweise bekannt geworden. Bei dieser Ausführung zielt die Verbindung der beiden Achsbrücken mittels Zapfenführung auf eine torsionsweiche Verbindung dieser Achsbrücken, womit die Entgleisungssicherheit dieser Fahrzeuge sichergestellt wird. Dies verunmöglicht jedoch eine kurvenradiale Einstellung der Räder, wie dies für kurvenreiche Strecken mit engen Kurvenradien ein unbedingtes Erfordernis darstellt. Während eine radaussenseitige Abstützung eine optimale Niederflurbauweise erlaubt, erfolgt hier die Abstützung des Kastens zwischen den Rädern.From WO-A 85/05602 a divisible bogie in the articulated area of tram vehicles in low-floor construction has become known. In this version, the connection of the two axle bridges by means of a pin guide aims at a torsionally soft connection of these axle bridges, which ensures the derailment security of these vehicles. However, this makes it impossible to set the wheels in a curve-radial manner, which is an essential requirement for winding routes with tight curve radii. While a wheel-side support allows an optimal low-floor construction, the box is supported between the wheels.

Auch die GB-A- 892 485 offenbart einen Wagenkasten, an dessen Enden Einzelachsfahrwerke angeordnet sind. Bei dieser Konstruktion ist ebenfalls eine kurvenradiale Einstellung der Räder nicht möglich, da die Achsbrücke direkt mit dem Wagenkasten über Lenker verbunden ist. Daher ist eine Ausdrehung der Radbrücken bei dieser Ausführung unmöglich, womit eine Radeinstellung bei dieser Konstruktion nicht stattfinden kann.GB-A-892 485 also discloses a car body, at the ends of which single axle bogies are arranged. With this construction, it is also not possible to set the wheels in a radial curve, since the axle bridge is connected directly to the car body via handlebars. It is therefore impossible to unscrew the wheel bridges in this version, which means that wheel adjustment cannot take place in this construction.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung, wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe, ein Niederflur-Fahrgestell mit Fahrgestellrahmen so auszubilden, dass der Niederflurwagenkasten vom Fahrgestellrahmen getragen wird und dass die beim Befahren von Strecken mit Kurvenradien auftretenden Schwierigkeiten aber dennoch vermieden werden.The invention seeks to remedy this. The invention, as characterized in the claims, solves the problem of designing a low-floor chassis with a chassis frame in such a way that the low-floor car body is carried by the chassis frame and that the difficulties encountered when driving on curves with curves are nevertheless avoided.

Die durch die Erfindung erreichten Vorteile sind im wesentlichen darin zu sehen, dass ein stufenloser, mit durchgehendem Boden, in extremer Leichtbauweise ausgeführter Niederflurwagenkasten verwendet werden kann und dass trotz dem den Wagenkasten tragenden Fahrgestellrahmen Bogenfahrten geräuschlos und verschleissfrei ausgeführt werden können. Im weiteren wird durch die Erfindung eine vollständige Vormontage des Fahrgestells ermöglicht, so dass die Wagenkästen im nachhinein nur noch auf den Fahrgestellrahmen aufgesetzt und mit diesem verbunden zu werden brauchen.The advantages achieved by the invention can be seen essentially in the fact that a stepless, with continuous floor, can be used in an extremely lightweight design low-floor car body and that despite the chassis frame supporting the car body arches can be carried out noiselessly and without wear. Furthermore, a complete pre-assembly of the chassis is made possible by the invention, so that the car bodies only have to be placed on the chassis frame afterwards and connected to it.

Das Wageninnere weist keine Podeste auf und ist über einen Steig 12 stufenlos erreichbar. Im Fahrgestellbereich sind unter den Sitzplätzen 9.2 Aussparungen in der Form von Radkästen 9.1 vorgesehen, in denen bestimmte Teile des Fahrgestells 1 angeordnet sind. Der Niederflurwagen wird von einer Fahrleitung 13 über einen Stromabnehmer 14 mit elektrischer Energie versorgt. Das Fahrgestell 1 besteht aus zwangsgesteuerten Einzelrad-Einzelfahrwerken 2, einem die Einzelrad-Einzelfahrwerke 2 verbindenden Längsmitnehmer 3, je Breitseite aus einem Antrieb 4, einem Fahrgestellrahmen 5 und aus einer Fahrwerksteuerung 6. An der dem Gelenk 8 gegenüberliegenden Schmalseite greift eine Zug-Stossvorrichtung 7 an. Ein Einzelrad-Einzelfahrwerk 2 weist zwei Einzelräder 2.1 mit Achsschenkeln 2.2.1 auf, die über eine schmalseitig liegende, gekröpfte Radbrücke 2.2 verbunden sind. Radaussenseitig sind Radgetriebe 2.3 und Kastenfederungen 2.6 vorgesehen.1 to 10, a low-floor car consisting of two end boxes 9 and a center box 10 is shown. The end boxes 9 are each carried by a chassis 1. The wheel-free center box 10 is supported on a narrow side via a joint 8 on the chassis 1. The low-floor car is bound to rails 11. The interior of the car has no platforms and can be reached continuously via a path 12. In the chassis area under the seats 9.2 there are recesses in the form of wheel arches 9.1 in which certain parts of the chassis 1 are arranged. The low-floor car is supplied with electrical energy by a contact line 13 via a current collector 14. The undercarriage 1 consists of positively controlled single-wheel single undercarriages 2, a longitudinal driver 3 connecting the single-wheel single undercarriages 2, on each broad side of a drive 4, a undercarriage frame 5 and a undercarriage control 6 at.

In einer ersten Ausführungsvariante stützen sich die Kastenfederungen 2.6 über elastische Federauflagen 2.7 auf Getriebegehäusen 2.4 ab. Die elastischen Federauflagen 2.7 ermöglichen eine kurvenabhängige Horizontalverdrehung der Einzelrad-Einzelfahrwerke 2. In einer weiteren Ausführungsvariante ist eine von den Getriebegehäusen 2.4 getrennte Federabstützung vorgesehen. Die Kastenfederungen 2.6 stützen sich auf Federträgern 2.5 ab, welche auf den Achsschenkeln 2.2.1 gelagert sind. Kugeldrehkranz-Segmente 2.8 ermöglichen eine kurvenabhängige Horizontalverdrehung der Einzelrad-Einzelfahrwerke 2. In beiden Ausführungsvarianten dämpfen die als Flexicoilfedern ausgebildeten Kastenfederungen 2.6 und die elastischen Federauflagen 2.7 die Wankbewegungen der Wagenkästen.In a first embodiment variant, the box springs 2.6 are supported on gear housings 2.4 by means of elastic spring supports 2.7. The elastic spring supports 2.7 enable a curve-dependent horizontal rotation of the individual wheel individual undercarriages 2. In a further embodiment variant, one of the transmission housings 2.4 separate spring support provided. The box springs 2.6 are supported on spring supports 2.5, which are mounted on the steering knuckles 2.2.1. Ball slewing ring segments 2.8 enable a curve-dependent horizontal rotation of the single-wheel single undercarriage 2. In both versions, the box springs 2.6 designed as flexicoil springs and the elastic spring supports 2.7 dampen the rolling movements of the car bodies.

Die Radbrücke 2.2 ist mittig mittels einem Drehzapfen an einen Mitnehmerträger 3.1 angelenkt, der über Mitnehmerstangen 3.2 und einen Mitnehmer-Ausgleichshebel 3.3 Traktions- und Bremskräfte auf den Fahrgestellrahmen 5 überträgt. Je Breitseite ist am Fahrgestellrahmen 5 ein Triebmotor 4.1 mit Stirnradgetriebe 4.2 und Bremsscheibe 4.5 sowie ein Federspeicher-Bremsgerät 4.4 angeordnet.

Mit 2.9 ist eine Elektromagnet-Schienenbremse bezeichnet.The wheel bridge 2.2 is articulated in the center by means of a pivot pin to a driver carrier 3.1, which transmits traction and braking forces to the chassis frame 5 via driver rods 3.2 and a driver compensating lever 3.3. A drive motor 4.1 with spur gear 4.2 and brake disk 4.5 as well as a spring brake device 4.4 is arranged on each chassis on the chassis frame 5. The drive motor 4.1 drives the broadside individual wheels 2.1 on the outside of the wheel via cardan shafts 4.3. In a further embodiment variant, chassis 1 without drive 4 are provided. 2.9 is an electromagnetic rail brake.
