Description

Die Erfindung betrifft einen Radsatz für Schienenfahrzeuge, insbesondere für hohe Geschwindigkeiten.The invention relates to a wheel set for rail vehicles, especially for high speeds.

Bei herkömmlichen Radsätzen sind die beiden Räder fest mit der Radsatzwelle verbunden, die unmittelbar neben den Rädern gelagert ist. Dabei können die Radsatzlager zwischen den Rädern (Innenlagerung) oder außen vor den Rädern (Außenlagerung) angeordnet sein. Durch den Abstand von Radmitte zur Radsatzlagermitte entsteht unter Last ein Biegemoment, das sich über diesem Abstand aufbaut und im Mittelteil der Radsatzwelle konstant ist. Da dieses Biegemoment die Radsatzwelle wechselnd beansprucht, erbringt ihre entsprechende Dimensionierung ein erhebliches Gewicht; ihre ungefederte Masse trägt nachteilig zu einer erhöhten Rad- und Gleisbeanspruchung bei. Bei angetriebenen Radsätzen erfordert eine durchgehende Radsatzwelle eine aufwendige Auslegung der Antriebseinrichtung, z.B. spezielle Achsgetriebe, Hohlwellengetriebe, Antriebe für Elektromotoren.In conventional wheel sets, the two wheels are firmly connected to the wheel set shaft, which is mounted directly next to the wheels. The wheelset bearings can be arranged between the wheels (inner bearing) or outside in front of the wheels (outer bearing). The distance from the center of the wheel to the center of the wheelset bearing creates a bending moment under load that builds up over this distance and is constant in the central part of the wheelset shaft. Since this bending moment alternately stresses the wheelset shaft, its corresponding dimensioning carries a considerable weight; their unsprung mass adversely contributes to increased wheel and track stress. With driven wheel sets, a continuous wheel set shaft requires a complex design of the drive device, e.g. special axle drives, hollow shaft drives, drives for electric motors.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Radsatz zu schaffen, bei dem insbesondere die ungefederten Massen geringer sind und einfachere Antriebseinrichtungen eingesetzt werden können.The invention is therefore based on the object of creating a wheel set in which, in particular, the unsprung masses are lower and simpler drive devices can be used.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Radsatz aus zwei jeweils ein Rad aufnehmenden, beidseits des Rades mit je einem Lager versehenen Tragteilen und einem die einander zugewandten Enden der Tragteile verbindenden Zwischenstück, z.B. einem dünnwandigen Distanzrohr, Getriebe oder einer Bremse, besteht.This object is achieved according to the invention in that the wheel set consists of two supporting parts, each receiving a wheel and provided with a bearing on both sides of the wheel, and an intermediate piece connecting the mutually facing ends of the supporting parts, e.g. a thin-walled spacer tube, gearbox or brake.

Die bei dem Radsatz nach der Erfindung erfolgte Begrenzung der Tragteile auf den Bereich eines jeden Rades erbringt vorteilhaft eine wesentliche Verkleinerung des Gewichtes und der ungefederten Massen und dadurch bessere Laufeigenschaften sowie geringeren Verschleiß an Rad und Schiene. Weiter vorteilhaft ist dieser Radsatz nach dem Baukastenprinzip durch variable Ausführungen des Zwischenstückes vielfältig, z.B. für Fahrzeuge unterschiedlicher Gattung oder Spürweite, für Lauf- oder Triebdrehgestelle oder für unterschiedliche Bremssysteme verwendbar. Überdies ist eine einheitliche Ausbildung der Partie Rad-Tragteil-Lager und damit eine wirtschaftliche Herstellung möglich. Schließlich ist ein Einzelradwechsel gegeben, wodurch Wartung und Instandhaltung verbessert werden.The limitation of the supporting parts to the area of each wheel in the wheelset according to the invention advantageously results in a substantial reduction in weight and unsprung masses and thereby better running properties and less wear on the wheel and rail. This modular set of wheels is also advantageous due to the variable design of the intermediate piece, e.g. Can be used for vehicles of different types or track widths, for bogies or motor bogies or for different braking systems. In addition, a uniform design of the batch of wheel and supporting part bearings and thus economical production is possible. Finally, there is a single wheel change, which improves maintenance and repair.

Zum fahrzeugseitigen Anschluß dieses Radsatzes ist in Ausgestaltung nach der Erfindung vorgesehen, daß die beiden Lager eines jeden Tragteiles miteinander durch eine gabelförmige, am Fahrzeugaufbau oder am Drehgestell angreifen- - de Halterung verbunden sind.For the vehicle-side connection of this wheel set, it is provided in an embodiment according to the invention that the two bearings of each support part are connected to one another by a fork-shaped holder which engages the vehicle body or the bogie.

Für radiale Einstellungen der Radsätze im Betrieb sieht ein weiteres Merkmal nach der Erfindung vor, daß die beiden gabelförmigen Halterungen des Radsatzes miteinander verbunden und in einem am Fahrzeugaufbau oder am Drehgestell angeordneten Festpunkt im Sinne einer radialen Einstellbarkeit des Radsatzes angelenkt sind.For radial settings of the wheel sets in operation, a further feature according to the invention provides that the two fork-shaped brackets of the wheel set are connected to one another and articulated in a fixed point arranged on the vehicle body or on the bogie in the sense of a radial adjustability of the wheel set.

Eine Weiterbildung nach der Erfindung besteht darin, daß die gabelförmige Halterung zur Aufnahme einer an dem entsprechenden Rad angreifenden Scheibenbremse ausgebildet ist. Durch diese Ausbildung der Halterung werden sonst erforderliche Zusatzteile für die Aufnahme der Scheibenbremse vermieden, wodurch weiter die auf den Radsatz einwirkende ungefederte Masse verringert wird.A further development according to the invention is that the fork-shaped holder is designed to receive a disc brake acting on the corresponding wheel. This design of the bracket avoids any additional parts required for receiving the disc brake, which further reduces the unsprung mass acting on the wheel set.

Eine kompaktere Bauweise des Radsatzes und eine direkte Kraftübertragung im Bereich seiner Tragteile wird entsprechend einer letzten Ausgestaltung nach der Erfindung dadurch erzielt, daß jedes Lager über eine in seiner Vertikalachse angeordnete Feder gegen den Fahrzeugaufbau oder diesen tragende Bauteile, z.B. Rahmenteile eines Drehgestelles, abgestützt ist.A more compact design of the wheelset and a direct power transmission in the area of its supporting parts is achieved according to a last embodiment according to the invention in that each bearing is arranged via a spring arranged in its vertical axis against the vehicle body or components carrying it, e.g. Frame parts of a bogie is supported.
