Description

Die Erfindung betrifft ein angetriebenes Einzelrad-Fahrwerk für Niederflur-Stadtbahnwagen unterschiedlicher Spurweite.The invention relates to a driven single wheel undercarriage for low-floor light rail vehicles of different track widths.

Die Aufgabe der Erfindung besteht in folgendem: Es soll ein Fahrwerk geschaffen werden, das einen Stadtbahn­wagen mit einem extrem niedrigen, vorzugsweise einstufig zugänglichen Fußboden ermöglicht. Unterschiedliche Spurweiten - z.B. Normalspur oder Meterspur - sollen ohne wesentliche Veränderungen des Fahrwerkes erzielbar sein. Weiter ist zu berücksichtigen, daß das Fahrwerk zum einen die Außenkontur des Wagenkastens nicht überragt, zum anderen einer bequemen Breite eines im Fußboden enthaltenen Mittelganges nicht ent­gegensteht; ersteres ist insbesondere bei normalspurigen Fahrzeugen problematisch, letzteres bei meterspurigen.The object of the invention is as follows: A chassis is to be created which enables a light rail car with an extremely low, preferably one-step accessible floor. Different track gauges - e.g. Normal gauge or meter gauge - should be achievable without significant changes to the chassis. It must also be taken into account that the undercarriage on the one hand does not protrude beyond the outer contour of the car body, and on the other hand does not prevent a comfortable width of a central aisle contained in the floor; the former is particularly problematic for standard-gauge vehicles, the latter for meter-gauge vehicles.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß am Längsträger eines Fahrwerkrahmens eine schwenkbare Radein­heit sowie ein Fahrmotor und ein die Radeinheit mit dem Fahr­motor verbindendes Getriebe angeordnet sind, wobei der Quer­träger eine die Spurweite des Fahrwerkes erbringende Länge aufweist.This object is achieved in that a pivotable wheel unit and a traction motor and a gear unit connecting the wheel unit to the traction motor are arranged on the longitudinal member of a chassis frame, the cross member having a track width of the chassis.

Nach einer vorteilhaften Ausführungsform der Erfindung sind die schwenkbare Radeinheit, der Fahrmotor und das Getriebe zu einem kompakten, mit dem Längsträger des Fahrwerkes ver­bindbaren Antriebsaggregat vereinigt.According to an advantageous embodiment of the invention, the pivotable wheel unit, the drive motor and the transmission are combined to form a compact drive unit which can be connected to the longitudinal member of the chassis.

Eine weitere, für die beengten Raumverhältnisse günstige Aus­gestaltung der Erfindung besteht darin, daß der Fahrmotor rechtwinklig zur Längsrichtung des Fahrwerkrahmens angeordnet ist, wobei das Getriebe als Stirnradgetriebe ausgebildet ist.A further embodiment of the invention which is favorable for the confined spaces is that the drive motor is arranged at right angles to the longitudinal direction of the undercarriage frame, the gear being designed as a spur gear.

Im Hinblick auf eine noch kompaktere und vom Gewicht her günstige Ausbildung des Fahrwerkes ist gemäß einer nächsten Ausgestaltung der Erfindung vorgesehen, daß der Längsträger des Fahrwerkrahmens überwiegend durch das Gehäuse des Ge­triebes gebildet ist.With a view to an even more compact and weight-favorable design of the undercarriage, according to a next embodiment of the invention it is provided that the longitudinal member of the undercarriage frame is predominantly formed by the housing of the transmission.

Um das Fahrwerk auch unter den bestehenden räumlichen Zwän­gen mit einem Bremssystem auszurüsten, ist gemäß einer Aus­gestaltung der Erfindung vorgesehen, daß auf der Welle des Fahrmotors eine Bremsscheibe angeordnet ist. Diese Brems­scheibe befindet sich je nach vorliegender Spurweite inner­halb bzw. außerhalb des Fahrwerkrahmens.In order to equip the undercarriage with a braking system even under the existing spatial constraints, it is provided according to one embodiment of the invention that a brake disk is arranged on the shaft of the traction motor. Depending on the track gauge, this brake disc is located inside or outside the chassis frame.

Nach einer weiteren Ausführungsform der Erfindung ist an einem zusammen mit der Radeinheit horizontal schwenkbaren Radausleger eine Magnetschienenbremse aufgehängt. Diese Bremse hat stets eine günstige Position in bezug auf die Schiene.According to a further embodiment of the invention, a magnetic rail brake is suspended from a wheel bracket which can be pivoted horizontally together with the wheel unit. This brake always has a favorable position in relation to the rail.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher beschrieben. Die Figuren 1 und 2 zeigen jeweils in Draufsicht eine Hälfte eines Einzelrad-Einzelfahrwerkes für Niederflur-Stadtbahn­wagen, wobei jedes dieser beiden Fahrwerke in bezug auf die Längsachse L symmetrisch ausgebildet ist.An embodiment of the invention is shown in the drawing and will be described in more detail below. FIGS. 1 and 2 each show a top view of one half of an individual wheel single undercarriage for low-floor light rail vehicles, each of these two undercarriages being symmetrical with respect to the longitudinal axis L.

Das Fahrwerk nach Fig. 1 ist für Normalspur, das nach Fig. 2 für Meterspur vorgesehen. Beide Fahrwerke haben einheitliche Antriebsaggregate, die im wesentlichen jeweils aus einer Einzel- oder Losräder aufweisenden Radeinheit 1, einem damit verbundenen Stirnradgetriebe 2 und einem Fahrmotor 3 beste­hen. Die Radeinheiten 1 sind um Hochachsen 1b (siehe Fig. 2) schwenkbar gelagert und in ihrer Schwenkbewegung durch eine an Radauslegern 1a angreifende Spurstange 1c miteinander ge­kuppelt. Das Schwenken der Radeinheiten 1 entsprechend dem Schienenverlauf kann aufgrund der Spurführungskräfte selbst­lenkend erfolgen, alternativ ist eine aktive, beispielsweise auf die Spurstange 1c einwirkende Steuerung möglich.The chassis according to FIG. 1 is provided for normal gauge, that according to FIG. 2 for meter gauge. Both undercarriages have uniform drive units, each consisting essentially of a wheel unit 1 having single or idler wheels, a spur gear 2 connected thereto and a drive motor 3. The wheel units 1 are pivotally mounted about vertical axes 1b (see FIG. 2) and are coupled to one another in their pivoting movement by a tie rod 1c acting on the wheel arms 1a. The pivoting of the wheel units 1 in accordance with the course of the rail can be self-steering due to the guidance forces, alternatively an active control, for example acting on the tie rod 1c, is possible.

Die parallel zur Längsachse L angeordneten Gehäuse 2a der Stirnradgetriebe 2 sind Bestandteil von Längsträgern 10 des Fahrwerkrahmens, der durch tiefliegende Querträger 4 vervollständigt wird. Der Fahrmotor 3 ist rechtwinklig zu dem Stirnradgetriebe 2, also in Querrichtung des Fahrwerkes angeordnet. Die Motorwelle 3a trägt eine Bremsscheibe 5, die mit einer durch ein Federspeicher-Bremsgerät 7 betrie­benen Bremszange 8 zusammenarbeitet. Bei der normalspurigen Ausführung nach Fig. 1 befindet sich die Bremsscheibe inner­halb, bei der meterspurigen Ausführung außerhalb des Fahr­werkrahmens.The housings 2a of the spur gear 2, which are arranged parallel to the longitudinal axis L, are part of the longitudinal members 10 of the chassis frame, which is completed by deep-lying cross members 4. The traction motor 3 is arranged at right angles to the spur gear 2, that is to say in the transverse direction of the running gear. The motor shaft 3a carries a brake disc 5 which cooperates with a brake caliper 8 operated by a spring-loaded brake device 7. In the standard-track version according to FIG. 1, the brake disc is inside, in the meter-track version outside the chassis frame.

Wie aus Fig. 1 ersichtlich, hat das Fahrwerk an den Gehäusen 2a der Stirnradgetriebe 2 angebrachte Federträger 2b zur federnden Abstützung (Luftfedern) des Aufbaues eines Stadt­bahnwagens; die Anlenkung in Längsrichtung erfolgt durch Lenkerstangen 9.As can be seen from FIG. 1, the undercarriage has spring supports 2b attached to the housings 2a of the spur gear 2 for resilient support (air springs) of the structure of a light rail vehicle; the linkage in the longitudinal direction is carried out by handlebar rods 9.

Mit dem angetriebenen Fahrwerk nach der Erfindung ist vor­teilhaft ein Stadtbahnwagen mit besonders niedrigem, vorzugs­weise einstufig zugänglichem Fußboden realisierbar, wobei - völlig unabhängig von der Spurweite - die Außenkontur des Wagenkastens (gestrichelt gezeichnete Linien A) keinesfalls durch Fahrwerksteile überragt wird und stets ein Fußboden­mittelgang (Begrenzungslinien F) mit sicher und bequem be­nutzbarer Breite vorliegt. Weiter günstig differieren die Fahrwerksausführungen "Normalspur" und "Meterspur" lediglich durch einfach längenmäßig angepaßte Querträger 4 und die Spurstange 1c.With the driven undercarriage according to the invention, a light rail car with a particularly low, preferably one-step accessible floor can be realized, whereby - completely independent of the track width - the outer contour of the car body (dashed lines A) is never exceeded by undercarriage parts and always a floor center aisle (boundary lines F) is available with a safe and convenient width. The chassis designs "standard gauge" and "meter gauge" differ further cheaply only by means of cross members 4 and the tie rod 1c which are simply adjusted in length.
