Abstract

The single wheel running gear incorporated into the coach body (1) dispenses with the system hitherto used in rail vehicle construction of autonomous track-guide running gear elements and bracket-guide carrier elements with their critical areas of rotation and the costly primary and secondary suspension devices. The abandonment of wheelset axles, independent bogie or running-gear frames permits extremely light constructions of the overall vehicle owing to the transfer of track-holding functions to the coach body in conjunction with the steered single wheel running gears and their associated spring elements. By arranging the wheels (3), supported on the inside in a wheel guide beam (6) and steerable at a tangent to the track curve radius, in lateral wheel boxes (2), it is possible to lower the floor of the coach below the wheel centre plane. Rail vehicles can thereby be built with continuous low floors (4) and single access steps (5) running in the longitudinal direction of the coach. The design principle adopted here leads to a significant reduction in the unladen weight of the coach, thereby reducing the drive energy input. In conjunction with the tangential steering of the wheels, this wheel guiding and track holding fixed by way of the coach body construction with a limited flexible gauge tolerance improves the running characteristics of the coach and greatly reduces the generation of running noise particularly on small track curves. The rolling resistances are hereby minimised and wheel and rail wear significantly reduced. <IMAGE>

Description

Die Erfindung bezieht sich auf ein Leichtbau-Schienenfahrzeug, insbesondere für den Personennahverkehr.The invention relates to a lightweight rail vehicle, in particular for local public transport.

Die DE-C-600 486 beschreibt ein Schienenfahrzeug, bei dem die Radsätze als gekröpfte, durchgehende Achsen mit ungelenkten Losrädern ausgeführt sind. Derartige Achskonstruktionen müssen stärker ausgelegt sein als gerade (nicht gekröpfte) Radsatzachsen, da durch die Achskröpfung Biegemomente bedingt sind, die zusätzlich zu den Fahrzeuglasten sowie den Beschleunigungsund Bremskräften von der Achskonstruktion aufzunehmen sind. Dadurch wird im vorliegenden Fall sowohl das Baugewicht als auch die Bauhöhe dieser Radsätze, die ohnehin gegenüber Einzelradaufhängungen bereits ein Mehrgewicht aufweisen, weiter vergrößert. Es ergibt sich damit trotz gekröpfter Radsatzachsen, eine Wagenbodenhöhe, die den heutigen Anforderungen an einen Niedrigwagenbogen nicht entspricht.DE-C-600 486 describes a rail vehicle in which the wheel sets are designed as cranked, continuous axles with unguided idler wheels. Axle constructions of this type must be designed to be stronger than straight (non-cranked) axles because the axle offset causes bending moments which have to be absorbed by the axle construction in addition to the vehicle loads and the acceleration and braking forces. In the present case, this further increases both the overall weight and the overall height of these wheel sets, which already have an additional weight compared to independent wheel suspensions. Despite cranked wheelset axles, this results in a car floor height that does not meet today's requirements for a low car arch.

Durch die FR-A-680 750 ist ein Schienenfahrzeug mit gekröpften Achsen und lenkbaren Rädern bekannt. Die Achsen sind in gesonderten Halterungen in einem Fahrwerksrahmen (Fahrschemel) befestigt. Die beiden Räder einer Achse werden mittels einer Spurstange parallel geführt und durch eine in der Spurstange angeordnete Spiralfeder jeweils bei Auslenkung wieder in Geradeaus-Fahrtrichtung zurückgestellt. Die Federkräfte müssen relativ hohe Werte annehmen, um bei Geradeausfahrt einen schlingerfreien und ruhigen Wagenlauf sicherzustellen. Bei dem bekannten Schienenfahrzeug erhält man deshalb nur eine unbefriedigende Kurvenlauffähigkeit, da bei Einfahrt des Schienenfahrzeuges in ein Bogengleis die relativ hohe, einseitige Feder-Rückstellkraft solange von dem anlaufenden Spurkranz aufzubringen ist, bis eine Radebeneneinlenkung in die Tangente der Gleiskurve erfolgt. Das Anlaufen des Spurkranzes führt zur Geräuschentwicklung sowie zum Verschleiß an Rad und Schiene. Darüber hinaus erhöht die Halterung der Achsen in einem Fahrwerksrahmen sowohl die Bauhöhe als auch das Gewicht der Achskonstruktion. Es ergibt sich damit eine Wagenbodenhöhe, die über der Radmittenebene liegt, so daß ein Niedrigwagenboden mit Einstufen-Einstieg, der den heutigen Anforderungen entspricht, nicht möglich ist.From FR-A-680 750 a rail vehicle with cranked axles and steerable wheels is known. The axles are fastened in separate brackets in a chassis frame (subframe). The two wheels of an axle are guided in parallel by means of a tie rod and reset by a spiral spring arranged in the tie rod each time they are deflected in the straight-ahead direction of travel. The spring forces must take on relatively high values to ensure that the wagon runs smoothly and smoothly when driving straight ahead. In the known rail vehicle, therefore, only an unsatisfactory cornering ability is obtained, since when the rail vehicle enters a curved track, the relatively high, One-sided spring restoring force is to be exerted by the approaching wheel flange until the wheel plane is steered into the tangent of the track curve. The tarnishing of the flange leads to noise and wear on the wheel and rail. In addition, the mounting of the axles in a chassis frame increases both the overall height and the weight of the axle construction. This results in a car floor height that is above the wheel center level, so that a low car floor with a single step entry that meets today's requirements is not possible.

Aufgabe der vorliegenden Erfindung ist es, bei einfacher, kleinbauender und geringgewichtiger Konstruktion ein fahrgastfreundliches Schienenfahrzeug zu schaffen, das im Vergleich zu den bisher bekannten Schienenfahrzeugen bei kompaktem Aufbau und hohem Fahrkomfort eine bessere Kurvenlauffähigkeit gewährleistet, jedoch den Fahrgästen einen wesentlich tieferliegenden Wagenboden, insbesondere einen durchgehenden Wagenboden mit nur einstufigem Einstieg, bei Verzicht auf gegenüber der Gleisebene erhöhten Bahnsteigkanten bietet.The object of the present invention is to provide a passenger-friendly rail vehicle with a simple, small-sized and light-weight construction which, in comparison to the rail vehicles known hitherto with a compact construction and high driving comfort, ensures better cornering ability, but the passengers have a substantially lower vehicle floor, in particular a continuous one Wagon floor with only one-step entry, but without platform edges that are higher than the track level.

Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen beschrieben.The object is achieved in a rail vehicle of the type mentioned by the features specified in claim 1. Advantageous embodiments of the invention are described in the subclaims.

Durch die erfindungsgemäße Konstruktion eines mit dem Wagenkasten konstruktiv verbundenen Einzelradfahrwerks mit horizontaler Schwenkbarkeit und Lenkbarkeit der Räder kann das Wagenlaufverhalten im Vergleich zu Fahr- und Drehgestellwagen, insbesondere in engen Gleisbögen, wesentlich verbessert werden, wobei durch den Wegfall von Radsatzachsen bzw. selbständiger Drehgestell- oder Fahrwerksrahmen sowie durch den Funktionsübergang der Spurhaltung in den Wagenkasten eine extreme Leichtbaukonstruktion erreicht wird und durch die TieflegungThe inventive construction of a single wheel undercarriage structurally connected to the car body with horizontal swiveling and steerability of the wheels, the wagon running behavior can be significantly improved compared to trolleys and bogie wagons, especially in narrow bends, with the elimination of axles or independent bogie or Undercarriage frame as well as an extreme lightweight construction is achieved by the function transition of the tracking in the car body and by the lowering

Eine hinsichtlich des notwendigen Einbauraums sehr kompakte und hinsichtlich des Einbaugewichtes sehr leichte und trotzdem betriebssichere Konstruktion der horizontal schwenk- und lenkbaren Einzelradaufhängung erhält man durch eine Ausgestaltung der Erfindung gemäß Anspruch 3, da bei dieser Ausführungsform die Bauteile des Radträgers, des Einzelrades, des Fahrmotors, des Planetengetriebes und der Scheibenbremse zu einer in der Radführungsschwinge horizontal schwenkbaren besonders kompakten Funktions- bzw. Baueinheit zusammenfaßbar sind.A construction of the invention according to claim 3 which is very compact with regard to the necessary installation space and very light in terms of installation weight and nevertheless reliable in operation of the horizontally pivotable and steerable independent wheel suspension is obtained, since in this embodiment the components of the wheel carrier, the single wheel, the drive motor, of the planetary gear and the disc brake can be combined to form a particularly compact functional or structural unit which can be pivoted horizontally in the wheel guide rocker.

Der Antrieb zwischen dem Fahrmotor und dem jeweiligen Einzelrad erfolgt in besonders vorteilhafter Weise gemäß einer Ausgestaltung der Erfindung nach Anspruch 5.The drive between the traction motor and the respective individual wheel takes place in a particularly advantageous manner according to an embodiment of the invention according to claim 5.

Die Erfindung sowie weitere vorteilhafte Ausgestaltungen der Erfindung werden im folgenden anhand eines in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Die Zeichnung zeigt in einem quer zur Wagenlängsachse verlaufenden Vertikalschnitt eine Einzelradaufhängung mit integriertem Fahrmotorantrieb.The invention and further advantageous embodiments of the invention are explained in more detail below with reference to an embodiment shown in the drawing.

In der Zeichnung ist mit 3 ein angetriebenes Einzelrad bezeichnet, das radial außen auf einem Radträger 9 drehbar gelagert ist. Der Radträger 9 ist seinerseits horizontal schwenkbar in einem Radkasten 2 eines Schienenfahrzeugs in einer Radführungsschwinge 6 drehbeweglich gehalten. Dazu ist das angetriebene Einzelrad 3 im Mittelteil der Radführungsschwinge 6 in vertikalen Gleit- oder Wälzlagern 12 bzw.12' horizontal schwenkbar gelagert.In the drawing, 3 denotes a driven single wheel, which is rotatably supported radially on the outside on a wheel carrier 9. The wheel carrier 9 is in turn horizontally pivoted in a wheel housing 2 of a rail vehicle in a wheel guide rocker 6 rotatably. For this purpose, the driven single wheel 3 is mounted in the middle part of the wheel guide rocker 6 in vertical slide or roller bearings 12 or 12 'horizontally pivotable.

Der Radkasten 2 ist integrierter Baubestandteil des Wagenkastens 1 , mit dem er an seiner Außenseite verbunden ist; an der Innenseite ist mit dem Radkasten 2 der unterhalb der Radmittenebene durchgehende Wagenboden 4 mit nur einstufigem Einstieg 5 verbunden. Die Radführungsschwingen 6 sind zweckmäßigerweise als kastenförmige, verdrehungssteife Träger aus Stahl, Leichtmetall oder kohlefaserverstärktem Kunststoff gebildet. Sie sind in einer in der Zeichnung nicht näher dargestellten Weise an ihrem einen Ende über Lagerböcke mit dem Wagenkasten 1 des Schienenfahrzeugs verbunden.The wheel arch 2 is an integral component of the car body 1, with which it is connected on its outside; on the inside is connected to the wheel arch 2, the continuous floor 4 below the wheel center plane with only one-step entry 5. The wheel guide rockers 6 are expediently formed as a box-shaped, torsion-resistant support made of steel, light metal or carbon fiber reinforced plastic. They are connected in a manner not shown in the drawing at one end to the car body 1 of the rail vehicle at one end via bearing blocks.

Als Einzelradantrieb dient ein Fahrmotor 10, dessen Rotorwelle 15 über schnellaufende ölgeschmierte Wälzlager 14 bzw.14' unmittelbar oder mittelbar über einen den Radträger 9 axial verschließenden Lagerdeckel 13 im Radträger 9 gelagert ist. Am rechten Ende der Rotorwelle 15 ist eine Bremsscheibe 16 befestigt, deren zugeordnetes Bremsjoch 17 am Radträger 9 gehalten ist. Das linke Ende der Rotorwelle 15 steht über ein Planetengetriebe 11 in Mitnahmeverbindung mit dem Einzelrad 3. Dazu ist der das Fahrmotorständergehäuse an seinem getriebeseitigen Ende verschließende Lagerdeckel 13 mit einer Außenverzahnung versehen, in die das äußere Zentralrad des Planetengetriebes 11 eingreift, wodurch das Reaktionsmoment der Planeten auf den Radträger 9 übergeleitet wird. In vorteilhafter Weise ist vorgesehen, daß das Planetengetriebe 11 durch eine mittig angeordnete Entlüftungsschraube 21, die mit ihrem Luftrohr in eine nach außen konische Bohrung der Rotorwelle 15 bzw. des inneren Zentralrades des Planetengetriebes eintaucht, entlüftet wird; dadurch ist neben einer Entlüftung des Planetengetriebes 11 auch auf einfache Weise Schutz vor Spritzöl gewährleistet.A traction motor 10 is used as a single-wheel drive, the rotor shaft 15 of which is mounted directly or indirectly in the wheel carrier 9 via high-speed oil-lubricated roller bearings 14 or 14 'via a bearing cover 13 which axially closes the wheel carrier 9. A brake disk 16 is attached to the right end of the rotor shaft 15, the associated brake yoke 17 of which is held on the wheel carrier 9. The left end of the rotor shaft 15 is in driving connection with the individual wheel 3 via a planetary gear 11. For this purpose, the bearing cover 13, which closes the drive motor stator housing at its end on the transmission side, is provided with external toothing in which the outer central wheel of the planetary gear 11 engages, as a result of which the planet's reaction moment is transferred to the wheel carrier 9. It is advantageously provided that the planetary gear 11 is vented by a centrally located vent screw 21, which dips with its air tube into an outwardly conical bore of the rotor shaft 15 or the inner central wheel of the planetary gear; in addition to venting the planetary gear 11, this also ensures protection from splash oil in a simple manner.

Die Schmierung des rechten, nicht im Ölsumpf des Planetengetriebes 11 befindlichen schnellaufenden Wälzlagers 14' erfolgt durch Staudrucköl. Der Staudruck wird nach einer Ausgestaltung der Erfindung aus dem umlaufenden Ölring zwischen dem Radträger 9 und der umlaufenden Radnabe 18 des Einzelrades 3 in einer in beiden Drehrichtungen arbeitenden Stauvorrichrung 19 erzeugt. Durch eine Bohrung im Radträger 9 wird das Staudrucköl dann dem Lager zugeführt; ein Standrohr 20 mit Rücklaufbohrung gewährleistet den erforderlichen gleichbleibenden Rücklauf.The right-hand high-speed roller bearing 14 ', which is not located in the oil sump of the planetary gear 11, is lubricated by dynamic pressure oil. According to one embodiment of the invention, the dynamic pressure is between the rotating oil ring the wheel carrier 9 and the revolving wheel hub 18 of the individual wheel 3 are produced in a stowage device 19 working in both directions of rotation. The dynamic pressure oil is then supplied to the bearing through a bore in the wheel carrier 9; a standpipe 20 with a return bore ensures the required constant return.
