Description

Die Erfindung betrifft eine Antriebseinheit für Schienenfahrzeuge, umfassend einen am Fahrzeugrahmen oder am Fahrwerk aufgehängten Elektromotor mit einem Getriebe und einer Kupplung, wobei die Radsatzwelle der beiden Treibräder durch eine Hohlwelle geführt ist und wobei zwischen dem aus der Radsatzwelle und den Treibrädern gebildeten Radsatz und dem Getriebe die Kupplung vorgesehen ist, in die die Hohlwelle mit einbezogen ist.The invention relates to a drive unit for rail vehicles, comprising one on the vehicle frame or on the chassis suspended electric motor with a gearbox and a clutch, the wheelset shaft of the two drive wheels by a Hollow shaft is guided and between which from the wheelset shaft and the drive wheels formed wheelset and the transmission the clutch is provided, in which the hollow shaft with is involved.

Bei einer bekannten Antriebseinheit dieser Art (Brown Boveri Mitteilungen 12-77, Seiten 714-723 "BBC-Gummigelenk-Kardanantrieb") ist der Antrieb um die Radsatzachse aufgebaut, wobei der achsparallel angeordnete Motor mit einem Stirnradgetriebe kombiniert ist und wobei der Antrieb zwei zentrische Gelenkhebel-Kupplungen umfaßt, die durch eine Hohlwelle miteinander verbunden sind, derart, daß ein Mitnehmer das Drehmoment vom Getriebe übernimmt und es der andere Mitnehmer auf den Radsatz überträgt. Wegen der hohen Beschleunigungskräfte im Hochgeschwindigkeitsverkehr werden solche vollabgefederten Antriebe mit Hohlwelle und vollständig vom Radsatz entkoppelten Motor- und Getriebemassen eingesetzt. Die Antriebseinheit ist dabei im Drehgestellrahmen gelagert und überträgt die Traktionskräfte über die die Relativbewegung zwischen Radsatz und Drehgestellrahmen ausgleichende, als Hohlwelle ausgeführte Kardanwelle, durch welche die Radsatzwelle geführt ist.In a known drive unit of this type (Brown Boveri Messages 12-77, pages 714-723 "BBC rubber joint cardan drive") the drive is built up around the wheelset axis, whereby the axially parallel motor with a spur gear is combined and the drive has two central articulated lever couplings includes each other by a hollow shaft are connected such that a driver torque from Gearbox takes over and it the other driver on the wheelset transfers. Because of the high acceleration forces in the High speed traffic will be such fully cushioned Drives with hollow shaft and completely decoupled from the wheelset Engine and transmission masses used. The drive unit is stored in the bogie frame and transmits the Traction forces over which the relative movement between wheelset and bogie frame compensating, designed as a hollow shaft Cardan shaft through which the wheelset shaft is guided is.

Bei diesem bekannten Antrieb ist eine mechanische Zusatzbremse in Form einer klassischen Klotzbremse ausgeführt, wobei die Bremsenergie direkt in die Lauffläche der Treibräder der Radsatzwelle einwirkt. Die durch die Traktion schon hochbelasteten Laufflächen der Treibräder werden damit noch höher belastet und dem Verschleiß ausgesetzt.In this known drive there is a mechanical auxiliary brake executed in the form of a classic block brake, whereby the braking energy directly into the tread of the driving wheels Wheelset shaft acts. Those who are already highly stressed by the traction The treads of the driving wheels are even higher strained and exposed to wear.

Bei Antrieben für Schienenfahrzeuge ist auch die Anordnung von Radscheibenbremsen bekannt, wobei den Treibrädern Backenbremseinrichtungen zugeordnet sind, welche die Bremsenergie auf Bremsscheiben übertragen, die beidseits der Treibräder aufgesetzt sind. Solche Radscheibenbremsen erfordern einen gewissen zusätzlichen Einbauraum. Die Gelenkhebel-Kupplung des eingangs beschriebenen bekannten BBC-Gummigelenk-Kardanantriebs läßt den Einbau von Radscheibenbremsen nicht zu oder setzt den Einbau sehr großer Treibräder voraus. Die zwei Kupplungshälften der Gelenkhebel-Kupplung vermindern zudem den axialen Bauraum für den Elektromotor.The arrangement is also the case for drives for rail vehicles known from wheel disc brakes, the driving wheels shoe brake devices are assigned which is the braking energy transferred to brake discs on both sides of the driving wheels are put on. Such wheel disc brakes require one certain additional installation space. The articulated lever coupling of the known BBC rubber joint cardan drive described at the beginning does not allow the installation of wheel disc brakes or requires the installation of very large driving wheels. The two Coupling halves of the articulated lever coupling also reduce the axial space for the electric motor.

Ein dem Motor nachgeordnetes Zwischengetriebe treibt über Bogenzahnkupplungen Antriebswellen an, die zu Getriebeteilen geführt sind, welche den Radsatzwellen zugeordnet sind und zu deren Antrieb dienen.EP 0 163 612 A2 describes a partially sprung drive for Rail vehicles with an electric motor suspended from the vehicle frame known. An intermediate gear downstream of the engine drives drive shafts via curved tooth couplings, which become gear parts are guided, which are assigned to the wheelset shafts are and serve to drive them.

Aufgabe der Erfindung ist es, einen voll abgefederten Antrieb der eingangs genannten Art zu schaffen, der sich durch einfachen Aufbau auszeichnet und zwischen den Treibrädern eines Radsatzes den Einbau eines leistungsfähigeren Elektromotors von größerer axialer Motorbaulänge ermöglicht.

Aufgrund ihrer hohen Leistungsdichte und der dadurch möglichen kompakten Bauform schafft die Bogenzahnkupplung einen großen axialen Einbauraum für einen leistungsfähigen Elektromotor. Wegen der in radialer Richtung klein ausführbaren erfindungsgemäßen Antriebseinheit steht ausreichender Einbauraum für Radscheibenbremsen an den Treibrädern zur Verfügung und es ist der Einbau eines einstufigen Getriebes möglich.Because of their high power density and the possible The curved tooth coupling creates a compact design large axial installation space for a powerful electric motor.

    Der Radsatz führt im Betrieb Bewegungen in drei verschiedenen Richtungen aus. Die dabei entstehende Auslenkung des Radsatzes kann bei axial nicht entkoppelten Kupplungen die gesamte Antriebseinheit zu Schwingungen anregen, was im allgemeinen unerwünscht ist. Die erfindungsgemäße Bogenzahnkupplung kann durch das Unterbinden der axialen Bewegungen an einem der Kupplungsteile die auftretenden Axialverschiebungen am anderen Teil der Kupplung im Zahneingriff durch Verrutschen der Zähne kompensieren. Dabei wird die Getriebeseite als "Festseite" gewählt, wobei die Verlegung der axialen Sicherung auf die Abtriebsseite eine Reduzierung des radialen Bauraumes getriebeseitig mit sich bringt und nur minimal die ungefederten Massen durch Ankoppelung der Kupplung über den elastischen Ring steigen läßt.The wheel set performs three different movements during operation Directions. The resulting deflection of the wheelset with axially uncoupled couplings, the entire Drive unit to vibrate, which in general is undesirable. The curved tooth coupling according to the invention can by preventing the axial movements on one of the Coupling parts the axial displacements that occur on the other Part of the clutch in meshing by slipping the Compensate teeth. The gear side is used as "Fixed side" selected, laying the axial securing on the output side, a reduction in the radial installation space transmission side and only minimally the unsprung Masses by coupling the coupling over the elastic ring can rise.
