Description

Die Erfindung bezieht sich auf ein zweirädriges Fahrwerk für spurgeführte Fahrzeuge mit einer traktionsgestützten Einrichtung zum Lenken und mit einem Radträger.The invention relates to a two-wheel chassis for track-guided vehicles with a traction-based device for steering and with a wheel carrier.

Nachdem spurgebundene und dabei insbesondere schienengeführte Fahrzeuge für den Schnell-, Regional- und Stadtverkehr fast ausschließlich mit Drehgestellfahrwerken ausgestattet worden sind, haben sich in letzter Zeit auch sogenannte Einzelradfahrwerke durchgesetzt. Während Drehgestelle zwei oder mehrere Radsätze oder vier oder mehr sogenannte Einzelräder haben und demzufolge sehr schwer sind, weisen Einzelradfahrwerke zwei Einzelräder bzw. Einzelradsatzfahrwerke einen Radsatz auf.After track-bound and in particular rail-guided vehicles for fast, regional and city traffic almost exclusively with bogie chassis have been equipped, so-called Independent wheel trolleys enforced. During bogies two or more wheel sets or have four or more so-called single wheels and therefore very much are heavy, single wheel trolleys have two single wheels or single wheel set trolleys a wheel set.

In Gleisbögen werden Drehgestelle durch den vorlaufenden Radsatz bzw. die vorlaufenden Einzelräder gelenkt. Durch den geringen Achsabstand bzw. Radstand ergibt sich ein geräusch- und verschleißarmer Bogenlauf der Räder und durch zwei oder mehr Drehgestelle unter dem Wagenkasten eine stabile Führung im geraden Gleis bei höheren Geschwindigkeiten. Eine zusätzliche Lenkung der Radsätze bzw. Einzelräder im Drehgestell wird durch die diagonale Verbindung zweier Radsätze untereinander oder die Ausnutzung der Winkelbewegungen vor- und nachlaufender Wagenkästen erzielt.In bends, bogies are created by the leading wheelset or the leading ones Steered single wheels. Due to the small center distance or wheelbase this results in a low-noise and low-wear arc run of the wheels and by two or more bogies under the car body a stable guide in the straight Track at higher speeds. Additional steering of the wheel sets or Single wheels in the bogie are made by the diagonal connection of two wheel sets with each other or the use of the angular movements leading and trailing Car bodies achieved.

Zweirädrige Einzelradfahrwerke haben insbesondere im Stadt- und Regionalverkehr Verbreitung gefunden. Einzelräder erleichtern dabei die konstruktive Ausführung eines einfachen Wageneinstiegs durch Absenkung des Wagenbodens auf ein Niveau von ca. 300 mm als sogenannte Niederflurfahrzeuge. Bei Einhaltung der sogenannten Abrollbedingung, welche durch nahezu gleiche Abroll- und Umfangsgeschwindigkeiten für die jeweils bogeninneren und bogenäußeren Räder gekennzeichnet ist, und der sogenannten Einstellbedingung, die das Einstellen der Radebenen tangential bzw. der Radachsen radial zu den Fahrschienen beschreibt, liegt eine nahezu physikalisch ideale Verschleiß- und Geräuschreduzierung und damit hoher Komfort vor. Zur Realisierung dieser idealen Spurführung kommen verschiedene Techniken zur Anwendung.Two-wheel single wheel trolleys have particular in city and regional traffic Spread found. Single wheels facilitate the design a simple car entry by lowering the car floor to Level of approx. 300 mm as so-called low-floor vehicles. In compliance with the so-called rolling condition, which by almost the same rolling and peripheral speeds marked for the inside and outside wheels and the so-called setting condition, which is the setting of the wheel planes describes tangential or the wheel axles radially to the rails an almost physically ideal wear and noise reduction and thus high comfort. There are various ways of realizing this ideal tracking Techniques for application.

Aus der "Nahverkehrs-Praxis" Nr. 11/1992, S. 402 ff. ist ein dreiteiliges Gelenkfahrzeug mit jeweils zwei Einzelradfahrwerken pro Wagenkasten bekannt. In einem Radträger sind zwei Einzelräder angeordnet, pro Wagen sind zwei Radträger jeweils um die Vertikalachse schwenkbar in dem Fahrwerksrahmen des Wagenkastens gelagert. Der vertikale Drehzapfen für die Schwenkachse befindet sich in der Mitte zwischen den Rädern des Radträgers in der Symmetrieebene des Fahrzeugs. Das bogenabhängige Schwenken bzw. Lenken der Radträger wird durch ein zusätzliches Lenkgestänge zum achsfreien Gelenk bewirkt. Das Lenkgestänge wird dabei in Abhängigkeit von dem sich bogenabhängig einstellenden Knickwinkel zwischen den Wagenkästen bewegt, so daß sich die Radträger annähernd bogenradial einstellen können. Eine ähnliche Zwangslenkung von Einzelradfahrwerken mit jeweils zwei Einzelrädern pro Fahrwerk mit einer portalähnlichen Gelenkkonstruktion wurde in Österreich entwickelt (vgl. ZEV + DET Glas. Annalen 116 (1992) Nr. 8/9, S. 333 ff).A three-part articulated vehicle is from "Nahverkehr-Praxis" No. 11/1992, p. 402 ff known with two single wheel bogies per car body. In one Two single wheels are arranged on the wheel carrier, two wheel carriers per carriage pivotable about the vertical axis in the chassis frame of the car body stored. The vertical pivot for the swivel axis is located in the Center between the wheels of the wheel carrier in the plane of symmetry of the vehicle. The bow-dependent swiveling or steering of the wheel carrier is made possible by an additional one Steering linkage to the axle-free joint causes. The steering linkage will depending on the bend angle that arises depending on the arc the car bodies moved, so that the wheel carrier almost radially arc can adjust. A similar forced steering of single wheel chassis with two individual wheels per chassis with a portal-like joint construction was developed in Austria (see ZEV + DET Glas. Annalen 116 (1992) No. 8/9, p. 333 ff).

Ein Einzelradfahrwerk mit selbstregelnden Einzelrädern wird in der DE 34 09 103 A1 und der DE 37 44 983 C2 beschrieben. Jedes der Einzelräder ist dabei um eine eigene vertikale Schwenkachse lenkbar. Die bogeninnen und -außen gegenüberliegenden Einzelradträger sind durch eine Spurstange verbunden. Durch die außerhalb der Radaufstandspunkte liegenden vertikalen Schwenkachsen werden die im Rad/Schiene-Kontakt entstehenden Kräfte genutzt, um die Radebenen tangential zur Fahrschiene zurückzuführen, so daß der Verschleiß zwischen Rad und Schiene erheblich reduziert wird.A single wheel chassis with self-regulating single wheels is in the DE 34 09 103 A1 and DE 37 44 983 C2. Each of the single wheels is steerable about its own vertical swivel axis. The arches inside and outside opposite independent wheel carriers are connected by a tie rod. Due to the vertical swivel axes located outside the wheel contact points the forces arising in the wheel / rail contact are used to the wheel planes traceable tangentially to the running rail, so that the wear between Wheel and rail is significantly reduced.

Aus der EP 02 95 462 B1 ist eine mit Stelleinrichtungen ausgestattete Einzelradfahrwerkkonstruktion bekannt. In einem Radträger sind zwei Einzelräder angeordnet, zwei Radträger sind jeweils um die Vertikale schwenkbar in einem Fahrwerksrahmen gelagert. Der die vertikale Schwenkachse konstruktiv realisierende Drehzapfen befindet sich in der Mitte zwischen den Rädern eines Radträgers in der Symmetrieebene des Fahrwerkrahmens. Das bogenabhängige Schwenken der Radträger wird durch eine Stelleinrichtung für jeden Radträger bewirkt, die sich am Fahrwerksrahmen abstützt und in Abhängigkeit von einem mit dem Wagenkasten gelenkig verbundenen benachbarten Wagenkasten jeden Radträger um den festen Drehpol in Radträgermitte schwenkt. EP 02 95 462 B1 describes a single wheel chassis construction equipped with adjusting devices known. Two single wheels are arranged in a wheel carrier, two wheel carriers are each pivotable about the vertical in a chassis frame stored. The pivot that realizes the vertical swivel axis is located in the middle between the wheels of a wheel carrier in the Plane of symmetry of the chassis frame. The bow-dependent swiveling of the Wheel carrier is effected by an adjusting device for each wheel carrier, which is located on the Support chassis frame and depending on one with the car body articulated adjacent car body each wheel carrier around the fixed Swivel pole swivels in the center of the wheel carrier.

Bei in Abhängigkeit vom Wagenkastenknickwinkel ausgeführten Bogensteuerungen für Einzelräder wächst der Fehler der bogenrichtigen Einstellung mit wachsendem Knickwinkel, ferner kann im Übergangsbogen eine exakte Tangentialstellung der Einzelradebenen nicht erreicht werden. Die zahlreichen Gelenke und Verbindungen des Lenkgestänges erfordern einen nicht unbeträchtlichen Wartungs- und Einstellaufwand.With bow controls depending on the body box angle for single wheels, the error of the correct alignment increases with increasing Kink angle, further an exact tangential position of the Single wheel planes cannot be reached. The numerous joints and connections of the steering linkage require considerable maintenance and adjustment effort.

Bei Einzelradfahrwerken mit selbstregelnden, einzeln angetriebenen Einzelrädern kann der Einfluß von Traktionskräften auf das Lenkverhalten zu unerwünschten Fahrbewegungen führen. Differenzantriebsmomente zwischen den Fahrmotoren sind fertigungstechnisch und thermisch nicht zu vermeiden und führen auf Differenztraktionskräfte, welche ein unerwünschtes Lenken hervorrufen können. Diese Differenztraktionskräfte können auch aus toleranz- oder querverschiebungsabhängigen Änderungen im Laufkreisradius der angetriebenen Einzelräder resultieren. Ferner verringert sich das Spurmaß dieser derart gelenkten Einzelräder bei sehr kleinen Gleisbogenhalbmessern und großem Achsabstand.For single wheel trolleys with self-regulating, individually driven single wheels the influence of traction forces on the steering behavior can lead to undesirable Lead movements. Differential drive torques between the traction motors cannot be avoided from a manufacturing and thermal point of view and lead to differential traction forces, which can cause unwanted steering. This Differential traction forces can also be dependent on tolerance or lateral displacement Changes in the running circle radius of the driven individual wheels result. Furthermore, the track dimension of these single wheels steered in this way is very reduced small track radius and large center distance.

Wird die Schwenkbewegung der um eine vertikale Achse drehbaren Radträger durch hydraulische Stellglieder bewirkt, so ist mit einem nicht unerheblichen Raumbedarf und Energieaufwand zu rechnen, da die der Lenkbewegung entgegenwirkenden Rad/Schiene-Kontaktkräfte durch die Stellglieder überwunden werden müssen. In der Bogenfahrt bewirkt ein Ausfall eines hydraulischen Stellglieds die Gefährdung der Fahrsicherheit. Ist der Einfluß der Traktionskräfte auf die Spurführung nicht zu eliminieren, so müssen die hydraulischen Stellglieder zusätzlich Traktionskraftdifferenzen kompensieren.Will the pivoting movement of the wheel carrier rotatable about a vertical axis effected by hydraulic actuators, with a not inconsiderable space requirement and energy expenditure to be expected since the counteracting the steering movement Wheel / rail contact forces can be overcome by the actuators have to. A failure of a hydraulic actuator causes the Danger to driving safety. Is the influence of the traction forces on the guidance the hydraulic actuators must not be eliminated Compensate for traction force differences.

Der Erfindung liegt daher die Aufgabe zugrunde, ein zweirädriges Fahrwerk mit Einzelradantrieb für spurgeführte Fahrzeuge mit gesteuerter Lenkung zu schaffen, welches mit minimalem Verschleiß, hoher Sicherheit und geringem konstruktiven Aufwand sowohl enge Gleisbögen durchfahren als auch höhere Geschwindigkeiten im geraden Gleis erzielen kann.The invention is therefore based on the object of having a two-wheel chassis To create independent wheel drive for track-guided vehicles with controlled steering, which with minimal wear, high security and low construction Effort driving through both narrow bends as well as higher speeds can achieve in a straight track.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale gemäß Anspruch 1 gelöst. Vorteilhafte Weiterbildungen des Erfindungsgegenstands sind in den Unteransprüchen enthalten. Die Erfindung vermeidet dabei die oben genannten Nachteile. This object is achieved by the features according to claim 1. Advantageous developments of the subject matter of the invention are in the subclaims contain. The invention avoids the disadvantages mentioned above.

Im Gegensatz zu den als bekannt beschriebenen Fahrwerken weist das erfindungsgemäß ausgebildete Fahrwerk pro Radträger mit zwei Einzelrädern keine mittige vertikale Schwenkachse auf, sondern zwei jeweils außerhalb der Radaufstandspunkte befindliche vertikale Schwenkachsen, wobei abwechselnd - unter Arretierung der Position der aktuell bogenäußeren Schwenkachse - der Radträger um genau diese Achse geschwenkt wird. Dabei wird der Radträger unter gezielter Aufbringung von Differenztraktionskräften tangential zur Fahrschiene eingestellt und durch eine separate Arretierung im gewünschten Lenkwinkel gehalten. Der gewünschte Lenkwinkel wird beispielsweise durch eine Spurlagemessung ermittelt, die Differenztraktionskräfte werden durch einen Stell- bzw. Regelalgorithmus vorgegeben.In contrast to the undercarriages described as known, this shows the invention trained chassis per wheel carrier with two single wheels none center vertical pivot axis, but two each outside the wheel contact points vertical swivel axes, alternately - under locking the position of the currently outer pivot axis - the wheel carrier around exactly this axis is pivoted. The wheel carrier is under targeted application of differential traction forces tangential to the rail and held in the desired steering angle by a separate lock. The one you want Steering angle is determined, for example, by a tracking measurement, the differential traction forces are specified by an adjustment or control algorithm.

Drehzapfen stellen eine konstruktive Realisierung der Schwenkachsen dar. Seitenbezogen wird der Radträger in Abhängigkeit vom Gleisbogenhalbmesser bei gleichzeitiger Arretierung der horizontalen Verschiebungsmöglichkeit des äußeren Schwenkachsenzapfens um diesen Schwenkachsenzapfen gelenkt. Die Schwenkbewegung kann auch aktiv, beispielsweise durch eine pneumatische oder hydraulische Schwenkeinrichtung oder durch gezieltes Aufbringen von Differenztraktionskräften bewirkt und gleichzeitig durch die Rad/Schiene-Kontaktkräfte unterstützt werden. Im schwach gebogenen oder geraden Gleis werden beide Schwenkachsen arretiert, so daß eine gute Stabilität bei höheren Geschwindigkeiten erzielt wird und der Einfluß toleranzbedingter Traktionskraftunterschiede gering bzw. vergleichbar mit nicht lenkbaren Fahrwerken ist. Die Lenkung und Arretierung wird durch geschickte Anordnung einer Feder-Dämpfer-Kombination unterstützt, so daß bei Ausfall der Fahrmotoren keine Gefährdung der Sicherheit zu befürchten ist.Pivots represent a constructive realization of the swivel axes the wheel carrier is dependent on the radius of the curve at the same time Locking the horizontal displacement possibility of the outer Swivel axis pin steered around this swivel axis pin. The swivel movement can also be active, for example by a pneumatic or hydraulic Swivel device or by applying differential traction forces effected and supported at the same time by the wheel / rail contact forces become. Both swivel axes are in the slightly curved or straight track locked so that good stability is achieved at higher speeds and the influence of tolerance-related differences in traction force is low or comparable with non-steerable undercarriages. The steering and locking is done by skillful Arrangement of a spring-damper combination supports, so that at Failure of the traction motors there is no risk to safety.

Die mit der Erfindung erzielbaren Vorteile bestehen insbesondere darin, daß keine zusätzliche Energie erfordernde Stelleinrichtungen für den Lenkvorgang notwendig sind, sondern die Differenztraktionskräfte des mit Einzelrad angetriebenen Einzelradfahrwerks als natürliche Stelleinrichtung den Lenkvorgang energiearm steuern und dabei durch die Rad/Schiene-Kontaktkräfte unterstützt werden.The advantages that can be achieved with the invention are in particular that none control devices requiring additional energy are required for the steering process are, but the differential traction forces of the single wheel driven single wheel chassis control the steering process with low energy as a natural control device and be supported by the wheel / rail contact forces.

Two-wheel bogie for track-guided vehicle with a traction-assisted device for steering and with a wheel carrier, characterised in that the two wheels (4 and 4') on the common wheel carrier (3) are aligned parallel to one another on a (notional) connecting line, which is perpendicular to the wheel circumference, between the individual wheel axes and are arranged at the same spacing from one another, that the wheel carrier (3) comprises two alternatively usable vertical pivot axles (2 and 2') disposed outside the wheel stand-up points, wherein merely one pivot axle (2, 2') is arranged at each side of the wheel carrier (3), which is displaceable in the horizontal, as well as fixable, in dependence on the rail curve diameter of the rail curve, wherein the wheel carrier (3) is steerable about the respective undisplaced pivot axis (2 or 2') which is inside the curve or outside the curve and disposed in a centre position and fixed.
    2. Bogie according to claim 1, characterised in that the pivot axes (kingpins 2 and 2') of the wheel carrier (3) are displaceable on arcuate segments (parts 5 and 5'), which are each arranged at a side in the bogie chassis (1), of the bogie.
    3. Bogie according to claim 1 or 2, characterised in that the vertical pivot axles are formed by kingpins (2 and 2').
    4. Bogie according to one of claims 1 to 3, characterised in that the vertical pivot axles are so embodied by thrust spring elements and/or guide links that the steering takes place about a virtually vertical pivot axis.
    5. Bogie according to one of claims 2 to 4, characterised in that one pivot axle is individually fixable in any desired setting of the arcuate bogie segment (parts 5 and 5'), whilst the respective other is in zero setting.
    6. Bogie according to one of claims 1 to 5, characterised in that the wheel carrier (3) is so articulated that the wheels (individual wheel 4 or 4') are always steered and/or guided radially relative to the traversed rail curve.
    7. Bogie according to one of claims 2 to 6, characterised in that the locking of a pivot axle (kingpins 2 and 2') of the wheel carrier (3) on the arcuate bogie segment is produced by the variable throttle cross-section of a spring/damper combination.
    8. Bogie according to one of claims 2 to 7, characterised in that the locking of a pivot axle (kingpins 2 and 2') of the wheel carrier (3) on the arcuate bogie segment (part 5 or 5') is produced by an electromagnetic and/or mechanical holding device.
    9. Bogie according to one of claims 2 to 7, characterised in that the locking of a pivot axle (kingpins 2 and 2') of the wheel carrier (3) on the arcuate bogie segment is produced by a spindle-and-nut construction driven by an electric motor.
    10. Bogie according to one of claims 2 to 9, characterised in that the displacement of a pivot axle of the wheel carrier (3) on the arcuate bogie segment is produced by differential traction forces of the individually driven wheels (4 and 4').
    11. Bogie according to one of claims 2 to 10, characterised in that the displacement of a pivot axle of the wheel carrier (3) on the arcuate bogie segment is produced by pneumatic and/or hydraulic setting devices.
    12. Bogie according to one of claims 2 to 10, characterised in that the displacement of a pivot axle of the wheel carrier (3) on the arcuate bogie segment is produced by a spindle-and-nut construction driven by an electric motor.
    13. Bogie according to one of claims 2 to 12, characterised in that the displacement of a pivot axle of the wheel carrier (3) on the arcuate bogie segment is effected by an electrically driven and/or motor-driven gearwheel, which drives a toothed ring along the arcuate bogie section.
    14. Bogie according to one of claims 1 to 13, characterised in that the wheel carrier (3) is steerable about the axle respectively at the outside of the curve.
    15. Bogie according to one of claims 1 to 13, characterised in that the wheel carrier (3) is steerable about the axle respectively at the inside of the curve.
