Description

Die Erfindung betrifft einen Einzelachsantrieb gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a single-axis drive according to the Preamble of claim 1.

Einzelachsantriebe dieser Art sind als Tatzlagerantriebe bekannt (HÜTTE des Ingenieurs Taschenbuch, 28. Auflage, HÜTTE IV A Elektrotechnik, Teil A, Berlin 1957, Verlag von Wilhelm Ernst & Sohn, Seiten 188, 189). Dabei hängt der Motor über zwei Tatzlager an der Radachse zwischen den Treibrädern und wird noch durch eine Pendelstütze oder eine Federaufhängung gegen das Fahrzeug- oder Drehgestell gehalten. Bei den verwendeten Motoren ist das an der Läuferwelle sitzende Ritzel fliegend gelagert und treibt über ein Großrad die Treibachse mit entsprechender Übersetzung an. Bei den üblichen Tatzlagerantrieben sind die den Motor auf der Radachse abstützenden Tatzlager getrennt von den Achslagern der Radachse ausgeführt. Das vom Ritzel und Großrad gebildete Getriebe ist von einem Zahnradschutzkasten umgeben. Diese Ausführungsform ist bei hohen Drehmomenten und/oder großen Übersetzungen technisch nur schwierig beherrschbar, da insbesondere bei einer Motorläuferwelle von geringerem Durchmesser und bei Verwendung eines kleinen Ritzels Durchbiegungen der Läuferwelle auftreten, was zu Schwierigkeiten beim Zahneingriff zwischen dem Ritzel und dem Großrad führt.Single-axis drives of this type are known as Tatzlagerantriebe (HÜTTE des Ingenieurs Taschenbuch, 28th edition, HÜTTE IV A Electrical Engineering, Part A, Berlin 1957, published by Wilhelm Ernst & Sohn, pages 188, 189). The engine overhangs two paw bearings on the wheel axle between the driving wheels and is still by a pendulum support or a spring suspension held against the vehicle or bogie. In the used Motors is the pinion on the rotor shaft overhung and drives the driving axle via a large wheel with the appropriate translation. With the usual Tatzlager drives are the ones that support the motor on the wheel axle Tatz bearings carried out separately from the axle bearings of the wheel axle. The gear formed by the pinion and large wheel is from surrounded by a gear box. This embodiment is technically at high torques and / or high gear ratios difficult to control, especially with one Motor rotor shaft of smaller diameter and when used a small pinion deflections of the rotor shaft occur, causing difficulty in meshing between the pinion and the big wheel.

Aus der GB-1 443 316 A ist ein Einzelachsantrieb für elektrische Triebfahrzeuge bekannt, bei dem das Gehäuse des elektrischen Antriebsmotors einschließlich eines damit verbundenen Übersetzungsgetriebes über Gleitlager, die mit einem Lagermaterial beschichtet sind, beidseitig auf den Außenringen der Lager für die Radachse abgestützt ist. Durch eine dieser Gleitlagerung gegenüberliegend angeordnete Drehmomentstütze ist der Antrieb am Fahrzeug- oder Drehgestell gehalten. Ein direkt auf der Läuferwelle des Motors angeordnetes Ritzel treibt ein auf der Radachse sitzendes Großrad an. Bei dieser Anordnung ist der Verschleiß an den Lagern der Radachse und ihren Führungsschultern sehr hoch, so daß der bekannte Antrieb allenfalls für geringere Leistungen geeignet ist. Hinzu kommen Schwierigkeiten bei der Wartung der Lager.GB-1 443 316 A is a single-axis drive for electrical Motor vehicles known in which the housing of the electrical Drive motor including an associated one Transmission gearbox on plain bearings with a bearing material are coated on both sides on the outer rings of the Bearing for the wheel axle is supported. Through one of these Torque support arranged opposite one another the drive is held on the vehicle or bogie. On Pinion arranged directly on the rotor shaft of the motor drives a large wheel sitting on the wheel axle. At this Arrangement is the wear on the bearings of the wheel axle and their shoulders very high, so that the well-known drive is at best suitable for lower performances. in addition there are difficulties in maintaining the bearings.

Die Läuferwelle des Motors trägt einen am abtriebsseitigen Wellenende vorgesehenen Achsansatz mit dem Ritzel, wobei eine antriebsseitige Außenlagerung der Läuferwelle mit einem äußeren Läuferwellenlager am Achsansatzstummel vorgesehen ist. Dieses Wälzlager ist in eine Lagerbohrung eines über ein Endschild mit dem Motorgehäuse verbundenen Lagerschildes eingesetzt. Über die weitere Ausbildung des Antriebssystems enthält die DE-91 15 647 U1, in der die eine Labyrinthdichtung betreffende EP 0 317 867 A1 zum Stand der Technik zitiert ist, keine Angaben. Ein Einzelachsantrieb entsprechend dem Oberbegriff des Auspruchs 1 ist auch aus der Druckschrift US 2 023 846 A bekannt. Aufgabe der Erfindung ist es, bei einem Einzelachsantrieb der eingangs genannten Art die in der beschränkten Leistung, dem hohen Verschleiß und der schwierigen Wartung liegenden Nachteile zu vermeiden und den Antrieb bezüglich der Übertragung von hohen Drehmomenten und/oder bei Anwendung großer Übersetzungen zu verbessern.DE-91 15 647 U1 is an electric drive motor known with a transmission gear, which consists of a pinion on the rotor shaft and a large wheel sitting on the wheel axle exists, with pinion and large wheel in a gear housing are arranged. The rotor shaft of the motor carries one provided on the output end of the shaft with the pinion, with a drive-side outer bearing of the rotor shaft with an outer rotor shaft bearing on the stub axle end is provided.

Nach der Erfindung ist die Läuferwelle des Motors außen gelagert, d.h. in der Anordnung antriebs- oder A-seitiges Läuferwellenlager - Ritzel - Läuferwelle - bürsten- oder B-seitiges Läuferwellenlager. Vorteilhaft dabei ist, daß im Vergleich zu einem fliegend gelagerten Ritzel geringere Lagerkräfte auftreten, daß eine höhere Lebensdauer der Lager erreicht wird und daß sich aufgrund einer geringeren Durchbiegung der Läuferwelle ein günstigerer Zahneingriff ergibt, was sich schonend auf das Getriebe auswirkt. In Anpassung an die Außenlagerung des Motors ist ferner vorgesehen, daß das antriebsseitige oder A-seitige Tatzlager zwischen dem zugeordneten A-seitigen Treibrad und dem Übersetzungsgetriebe und das B-seitige Tatzlager zwischen dem B-seitigen Motorlagerschild und dem B-seitigen Treibrad auf der Radachse abgestützt sind. Damit ist die Anordnung der Tatzlager vorteilhaft der Läuferwellenlagerung angepaßt. Da das antriebsseitige Tatzlager auf der dem A-seitigen Treibrad zugewandten Seite im Getriebegehäuse angeordnet ist, ergibt sich eine günstige Kraftübertragung von der außenseitigen Ritzellagerung über das Getriebegehäuse zum Tatzlager und zur Radachse.According to the invention, the rotor shaft of the motor is mounted on the outside, i.e. in the arrangement of drive or A-side rotor shaft bearings - Pinion - rotor shaft - brush or B-side Rotor shaft bearings. The advantage here is that compared to lower bearing forces occur with a cantilevered pinion, that a longer service life of the bearings is achieved and that due to less deflection of the rotor shaft a cheaper meshing results, which is gentle affects the transmission. In adaptation to the external storage the motor is further provided that the drive side or A-sided paw bearings between the assigned A-sided Driving wheel and the transmission gear and the B-sided Tatzlager between the B-side engine end shield and the B-side driving wheel are supported on the wheel axle. The arrangement of the Tatzlager is advantageous for the rotor shaft bearing customized. Because the drive-side peg bearing on the side facing the A-side drive wheel in the gearbox is arranged, there is a favorable power transmission from the outside pinion bearing over the Gear housing to the paw bearing and the wheel axle.

Bei dem dem Ritzel der Läuferwelle zugeordneten A-seitigen Läuferwellenlager und dem zugeordneten A-seitigen Tatzlager kann die Kraftübertragung noch dadurch verbessert werden, daß das Getriebegehäuse für das Großrad und das Ritzel tragend ausgebildet ist.With the A-side assigned to the pinion of the rotor shaft Rotor shaft bearing and the associated A-side bearing the power transmission can still be improved in that carrying the gearbox for the large wheel and the pinion is trained.

Für eine montagefreundliche Anordnung ist gemäß einer Weiterbildung der Erfindung im Getriebegehäuse im Bereich des Zahneingriffs zwischen Ritzel und Großrad eine Trennfuge vorgesehen, so daß dort die Getriebegehäuseteile lösbar befestigbar sind. In weiterer Ausgestaltung kann dabei das das A-seitige Tatzlager und das Großrad aufnehmende Getriebegehäuse durch ein das A-seitige Läuferwellenlager aufnehmendes A-seitiges Motorlagerschild zum kompletten Gehäuse ergänzt werden.For an assembly-friendly arrangement is according to a development of the invention in the gear housing in the area of the meshing between pinion and large gear one Parting line provided so that there the gear housing parts are releasably attachable. In a further embodiment, the gearbox housing the A-side paw bearing and the large wheel through a receiving the A-side rotor shaft bearing A-side motor end shield for the complete housing be supplemented.

Gemäß einer Weiterbildung der Erfindung ist vorgesehen, daß das zweite, B-seitige Tatzlager in ein B-seitiges Motorlagerschild integriert ist. Vorteilhaft dabei ist, daß ein eigenständiges Tatzlagergehäuse sowie dessen Befestigungen zum Motorgehäuse entfallen. Für eine einfache Montage ist vorgesehen, daß das B-seitige Motorlagerschild zur Anordnung des B-seitigen Tatzlagers eine lösbare Lagerhalbschale aufweist.According to a development of the invention it is provided that the second, B-side paw bearing in a B-side motor end shield is integrated. The advantage here is that an independent Patzlagerehäusen and its fastenings to the motor housing omitted. For easy assembly, that the B-side engine end shield for the arrangement of the B-side Tatzlager has a detachable half-shell.
