Abstract

Disclosed is a driving arrangement for an electric motor vehicle in which each of the two wheels of an axle is supported on separate shaft sections. Each motor or each rotor of a dual rotor motor drives only one driving wheel of an axle in order to mechanically decouple the driving wheels. One of the separate shaft sections of the axles includes a tapered portion which forms a shaft stub and the other shaft section includes a hollow shaft stub. The tapered shaft stub is supported in the hollow shaft stub by a slide bearing disposed inside the hollow shaft stub. Speed differences at the slide bearing between the axle sections can result only from slippage when negotiating a turn or from uneven wear of, for example, the wheels.

Description

Die Erfindung betrifft ein schienengebundenes elektrisches Triebfahrzeug, bei dem der elektrische Fahrmotor über Getriebe jeweils ein Treibrad antreibt, wobei beide Treibräder auf getrennten Wellenabschnitten befestigt sind, von denen einer zu einem Wellenzapfen ausläuft, während der andere einen Hohlwellenstumpf aufweist, die, ineinandergreifend und gegeneinander geführt, eine Treibachse bilden.The invention relates to a rail-bound electric traction vehicle, in which the electric traction motor drives a drive wheel via gears, both drive wheels being fastened on separate shaft sections, one of which runs out to a shaft journal, while the other has a hollow shaft stub, which, meshing and guided against one another , form a driving axis.

Ein derartiges Triebfahrzeug ist aus der DE-C-4 96 993 bekannt. Das von dem elektrischen Fahrmotor erzeugte Drehmoment wird bei dem bekannten Triebfahrzeug in üblicher Weise über das Ritzel auf das Großrad gegeben und dieses ist im Innern als Differentialgetriebe ausgebildet, so daß einerseits das Drehmoment auf die Hohlwelle und andererseits auf den Wellenzapfen übertragen werden, die jeweils eines der Treibräder tragen. Beide Achshälften greifen nur zum Zweck der axialen Arretierung ineinander, weshalb ein inneres Drucklager in Kombination mit einem inneren Schulterlager vorgesehen ist. Auf diese Weise sollen schädliche Auswirkungen auf das Differentialgetriebe verhindert werden. Gelagert sind die beiden Achshälften unabhängig voneinander. Die Lagerung der Achshälften mit dem Hohlwellenstumpf erfolgt mittels Tatzlager, während die andere Achshälfte, die den mittleren Wellenzapfen bilden, nur außerhalb der Hohlwelle im Differentialgetriebe gelagert ist. Die Lager müssen die volle Drehzahl der Achshälften aufnehmen, weshalb Wälzlager verwendet sind. Außerdem ist der Einsatz eines Differentialgetriebes sehr aufwendig.Such a locomotive is known from DE-C-4 96 993. The torque generated by the electric traction motor is given in the known locomotive in the usual way via the pinion on the large wheel and this is designed inside as a differential gear, so that on the one hand the torque is transmitted to the hollow shaft and on the other hand to the shaft journal, each one of the driving wheels. Both axle halves interlock only for the purpose of axial locking, which is why an inner thrust bearing is provided in combination with an inner shoulder bearing. This is to prevent harmful effects on the differential gear. The two axle halves are supported independently of each other. The axle halves with the hollow shaft stub are supported by means of a journal bearing, while the other axle half, which form the middle shaft journal, is only supported outside the hollow shaft in the differential gear. The bearings must absorb the full speed of the axle halves, which is why roller bearings are used. In addition, the use of a differential gear is very complex.

Weiterhin ist aus der EP-A-0 005 777 ein schienengebundenes elektrisches Triebfahrzeug bekannt, bei dem die einer Treibachse zugehörigen beiden Treibräder jeweils separat von einem elektrischen Fahrmotor angetrieben werden. Jedes Treibrad ist auf einer Hohlwelle befestigt und die beiden Hohlwellen sind jeweils auf einer gemeinsamen, stehenden Starrachse gelagert. Dadurch erreicht man eine mechanische Entkopplung der beiden Treibräder und der sonst bei Kurvenfahrten auftretende Schlupf eines der Räder wird vermieden. Bei der bekannten Anordnung steht an der Lagerung der Hohlwelle auf der Starrachse jeweils die volle Drehzahl der Treibräder an, was die Verwendung von fett-oder ölgeschmierten Lagern, insbesondere Wälzlager, erforderlich macht. Dadurch muß der Außendurchmesser der Hohlwellen verhältnismäßig groß gewählt werden. Weiterhin ist keine Federung mit dem Großrad und auch des Fahrmotors gegeben, wodurch sich die Laufeigenschaften verschlechtern.Furthermore, EP-A-0 005 777 discloses a rail-bound electric locomotive in which the two driving wheels associated with a driving axle are each driven separately by an electric traction motor. Each drive wheel is attached to a hollow shaft and the two hollow shafts are each mounted on a common, rigid axle. This results in a mechanical decoupling of the two drive wheels and the slippage of one of the wheels that otherwise occurs when cornering is avoided. In the known arrangement, the full speed of the drive wheels is applied to the mounting of the hollow shaft on the rigid axle, which necessitates the use of grease or oil lubricated bearings, in particular roller bearings. As a result, the outer diameter of the hollow shafts must be selected to be relatively large. Furthermore, there is no suspension with the large wheel or the drive motor, which worsens the running properties.

Ferner ist auch in der CH-A-4 52 584 eine mechanisch entkoppelte Achse beschrieben, deren Räder auf getrennten Wellenabschnitten angeordnet sind. Der eine Wellenabschnitt, der ein Rad trägt, besteht aus einer Hohlwelle, welche die andere Welle, die das andere Rad trägt, umgibt. Da es sich hierbei um eine reine Laufachse handelt, bei der keine Drehmomente auf die Räder übertragen werden, ist die Hohlwelle über Gleitlager auf der anderen Welle gelagert.CH-A-4 52 584 also describes a mechanically decoupled axle, the wheels of which are arranged on separate shaft sections. The one shaft section that carries one wheel consists of a hollow shaft that surrounds the other shaft that carries the other wheel. Since this is a pure running axle, in which no torques are transmitted to the wheels, the hollow shaft is supported on the other shaft via plain bearings.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, bei einem schienengebundenen elektrischen Triebfahrzeug die mechanische Entkopplung der Treibräder so vorzunehmen, daß ihr Raumbedarf und der Wartungsaufwand gering sind.The present invention has for its object to make the mechanical decoupling of the drive wheels in a rail-bound electric traction vehicle so that their space requirements and maintenance are low.

Zur Lösung dieser Aufgabe ist bei einem Triebfahrzeug der eingangs beschriebenen Art gemäß der Erfindung der Wellenzapfen über Gleitlager innerhalb des Hohlwellenstumpfes gelagert und der elektrische Fahrmotor ist als Doppelläufermotor ausgebildet, von dessen unabhängigen Läuferwellen jeweils eine mit einem Wellenabschnitt der Treibachse verbunden ist. Diese Gleitlager zwischen den beiden Wellenabschnitten, d. h. zwischen dem Wellenzapfen und dem Hohlwellenstumpf, wird jeweils nur durch geringe Drehzahldifferenzen belastet, nämlich nur durch die, die dem bei Kurvenfahrten oder durch unterschiedliche Abnutzung entstehenden Schlupf entsprechen würden. Dazu ist die Belastung der Gleitlager sehr gering und sie können entsprechend für geringen Raumbedarf und Wartungsaufwand ausgelegt werden. Außerdem wird die gegebene mechanische Entkopplung nicht durch die Läuferwelle des elektrischen Fahrmotors kurzgeschlossen, da dieser als Doppelläufermotor ausgebildet ist und somit zwei voneinander unabhängige Läuferwellen aufweist, von denen jeweils eine über das Getriebe einen Wellenabschnitt antreibt.To solve this problem, in a traction vehicle of the type described in the invention, the shaft journal is mounted via slide bearings within the hollow shaft stump and the electric traction motor is designed as a double-rotor motor, of which the independent rotor shafts are each connected to a shaft section of the drive shaft. These plain bearings between the two shaft sections, i. H. between the shaft journal and the hollow shaft stub is in each case loaded only by slight differences in speed, namely only by those that would correspond to the slip occurring when cornering or due to different wear. For this purpose, the load on the plain bearings is very low and they can be designed accordingly for little space and maintenance. In addition, the given mechanical decoupling is not short-circuited by the rotor shaft of the electric traction motor, since the latter is designed as a double-rotor motor and thus has two mutually independent rotor shafts, one of which drives a shaft section via the transmission.

Es ist besonders vorteilhaft, das Gleitlager zwischen Wellenzapfen und Hohlwellenstumpf trockengeschmiert auszubilden, weil dann keinerlei lagerbedingte Wartung notwendig ist.It is particularly advantageous to dry-lubricate the plain bearing between the shaft journal and the hollow shaft stub, because then no bearing-related maintenance is necessary.

Eine derartige mechanisch entkoppelte Treibachse eines Triebfahrzeuges kann sowohl bei Einzelachsantrieben als auch bei Zweiachsantrieben eingesetzt werden. Bei einem ZweiachsLängsantrieb empfiehlt es sich, daß zwei längsliegende Doppelläufermotoren jeweils einen Wellenabschnitt der beiden Treibachsen antreiben und daß die Doppelläufer ineinander gelagert sind.Such a mechanically decoupled driving axle of a traction vehicle can be used both with single-axle drives and with two-axle drives. With a two-axis longitudinal drive, it is recommended that two longitudinal double-rotor motors each drive one shaft section of the two drive axles and that the double-rotor bearings are mounted one inside the other.

Im folgenden sei die Erfindung noch anhand der in den Fig. 1 bis 3 dargestellten Ausführungsbeispiele näher erläutert.

  • Fig. 1 zeigt schematisch dargestellt einen senkrechten Schnitt durch die Treibachse eines Einzelachsantriebes. In
  • Fig. 2 ist der Teil eines Längsschnittes durch einen Zweiachsantrieb dargestellt und
  • Fig. 3 zeigt, ohne die dazugehörigen Fahrmotoren, teilweise im Schnitt, den Aufbau einer für einen im Drehgestell befestigten Antrieb geeigneten Treibachse.
The invention will be explained in more detail below with reference to the exemplary embodiments illustrated in FIGS. 1 to 3.
  • Fig. 1 shows schematically a vertical section through the drive axis of a single-axis drive. In
  • Fig. 2 is the part of a longitudinal section through a two-axis drive and
  • Fig. 3 shows, without the associated traction motors, partly in section, the structure of a drive axle suitable for a drive mounted in the bogie.

Bei dem in Fig. 1 dargestellten einachsigen Querantrieb eines schienengebundenen elektrischen Triebfahrzeuges ist der elektrische Fahrmotor 1 als Doppelläufermotor ausgebildet, d. h. die beiden in nicht dargestellter Weise unabhängig voneinander gelagerten und jeweils ein Ritzel 2 bzw. 3 antreibenden Läufer liegen innerhalb eines gemeinsamen Ständers und unterliegen somit einer gemeinsamen Erregung. Jedes Ritzel 2 bzw. 3 treibt über das Großrad 4 bzw. 5 einen Wellenabschnitt 6 bzw. 7 der Treibachse 8 an. Der Fahrmotor 1 ist mit Hilfe von Tatzlagern 9 und 10 auf beiden Wellenabschnitten 6, 7 gelagert.In the uniaxial transverse drive shown in Fig. 1 of a rail-bound electri rule the electric traction motor 1 is designed as a double-rotor motor, ie the two rotors, which are mounted independently of one another in a manner not shown and each drive a pinion 2 or 3, lie within a common stator and are therefore subject to common excitation. Each pinion 2 or 3 drives a shaft section 6 or 7 of the drive shaft 8 via the large wheel 4 or 5. The traction motor 1 is mounted on both shaft sections 6, 7 with the aid of paw bearings 9 and 10.

Auf jeden Wellenabschnitt 6 bzw. 7 der Treibachse 8 ist ein Treibrad 11 bzw. 12 befestigt. Der Wellenabschnitt 6 läuft an seinem dem Wellenabschnitt 7 zugewandten Ende zu einem Wellenzapfen 13 aus, der in das Innere des Hohlwellenstumpfes 14 hineinragt, den der Wellenabschnitt 7 aufweist. Zur zentrierenden Lagerung des Wellenzapfens 13 in dem Hohlwellenstumpf 14 dienen die beiden trocken geschmierten Gleitlager 15. An diesen steht jeweils nur die infolge Kurvenfahrt oder unterschiedliche Abnutzung der Treibräder 11 und 12 entstehende Schlupfdrehzahl an, so daß die Gleitlager 15 nur in ganz geringem Maß belastet werden.A drive wheel 11 or 12 is attached to each shaft section 6 or 7 of the drive shaft 8. At its end facing the shaft section 7, the shaft section 6 terminates in a shaft journal 13 which projects into the interior of the hollow shaft stub 14 which the shaft section 7 has. The two dry-lubricated slide bearings 15 serve to center the shaft journal 13 in the hollow shaft stub 14. Only the slip speed resulting from cornering or different wear of the drive wheels 11 and 12 is present, so that the slide bearings 15 are loaded only to a very small extent .

Durch diesen besonderen Aufbau der Treibachse 8 ist eine mechanische Entkopplung der beiden Treibräder 11 und 12 erreicht, wodurch die beim Betrieb des Triebfahrzeuges auftretende Geräuschentwicklung verringert ist und der Wartungsabstand für das Egalisieren der Treibraddurchmesser vergrößert werden kann.This special design of the drive axle 8 achieves mechanical decoupling of the two drive wheels 11 and 12, as a result of which the noise which occurs during operation of the locomotive is reduced and the maintenance interval for equalizing the drive wheel diameters can be increased.

Fig. 2 zeigt die Verwendung einer derartigen mechanisch entkoppelten Treibachse 8 bei einem Zweiachslängsantrieb. Für gleiche Teile wurden die gleichen Bezugszeichen beibehalten. Als elektrischer Fahrmotor für den Antrieb der beiden mechanisch entkoppelten benachbarten Treibachsen 8 dient ein Doppelläufermotorpaar, bestehend aus zwei in einem gemeinsamen Ständer 16 mit gemeinsamen Lagerschild 17 liegenden Doppelläufermotoren. Dadurch erzielt man eine Gewichtsersparnis und kann die Blechpakete in einem gemeinsamen Schnitt herstellen. Die beiden Läufer 18 und 19 bzw. 20 und 21 jedes Doppelläufermotors sind über einen Wellenzapfen 22 bzw. 23 ineinander gelagert. Dadurch ist auch für die durch jeden Doppelläufermotor angetriebenen benachbarten Wellenabschnitte 6 bzw. 7 der benachbarten Treibachsen eine mechanische Entkopplung gegeben.Fig. 2 shows the use of such a mechanically decoupled drive axle 8 in a two-axis longitudinal drive. The same reference numerals have been retained for the same parts. A pair of double-rotor motors, consisting of two double-rotor motors located in a common stator 16 with a common end plate 17, serves as the electric traction motor for driving the two mechanically decoupled adjacent drive axles 8. This saves weight and can produce the laminated cores in a single cut. The two rotors 18 and 19 or 20 and 21 of each double-rotor motor are mounted one inside the other via a shaft journal 22 or 23. This also provides mechanical decoupling for the adjacent shaft sections 6 and 7 of the adjacent drive axles driven by each double-rotor motor.

Die Läuferwelle 24 jedes Doppelläufermotors treibt jeweils über ein als Kegelrad ausgebildetes Ritzel 25 ein auf einem Wellenabschnitt 6 bzw. 7 angeordnetes Großrad 26 an. Das für jede Treibachse 8 gemeinsame Getriebegehäuse 27 ist über Wälzlager 28 auf den beiden Wellenabschnitten 6 bzw. 7 gelagert.The rotor shaft 24 of each double-rotor motor drives a large wheel 26 arranged on a shaft section 6 or 7 via a pinion 25 designed as a bevel gear. The common for each drive shaft 8 gear housing 27 is mounted on roller bearings 28 on the two shaft sections 6 and 7.

Bei der in Fig. 2 dargestellten Anordnung der Kegelräder 25 und 26 ist den Läufern 18 bzw. 20 der nebeneinander liegenden Doppelläufermotoren eine gegenläufige Drehrichtung vorgegeben. Im Fall gleichsinniger Drehrichtung der nebeneinander liegenden Doppelläufermotoren müßte ein Großrad 26 um 180° gedreht montiert werden, dann ergäben sich auch völlig identische Getriebe. Die mechanisch entkoppelten Treibachsen 8 lassen sich bei allen Längsantriebsprinzipien mit Doppelläufermotor anwenden, auch wenn diese einen anderen konstruktiven Aufbau als im Ausführungsbeispiel dargestellt aufweisen.In the arrangement of the bevel gears 25 and 26 shown in FIG. 2, the rotors 18 and 20 of the double-rotor motors lying next to one another are given an opposite direction of rotation. In the case of the direction of rotation of the double-rotor motors lying next to one another, a large wheel 26 would have to be mounted rotated by 180 °, which would result in completely identical gears. The mechanically decoupled drive axles 8 can be used with all longitudinal drive principles with a double rotor motor, even if they have a different construction than that shown in the exemplary embodiment.

Bei den in den Fig. 1 und 2 dargestellten Ausführungsbeispielen sind die Antriebsmassen des elektrischen Triebfahrzeuges nur beschränkt abfederbar, indem entsprechende Gummielemente in den Treibrädern selbst vorzusehen sind. Ein Ausführungsbeispiel, bei dem der elektrische Fahrmotor im Drehgestell befestigt oder, bei Zweiachslängsantrieben, schwebend angeordnet sein kann, um die Antriebsmassen abzufedern, ist der in Fig. 3 dargestellten Treibachse 8 ausführbar, bei dem ebenfalls für mit den bisherigen Ausführungsbeispielen übereinstimmende Teile die bisherigen Bezugszeichen beibehalten werden.In the embodiments shown in FIGS. 1 and 2, the drive masses of the electric traction vehicle can only be cushioned to a limited extent by providing appropriate rubber elements in the drive wheels themselves. An embodiment in which the electric traction motor is fastened in the bogie or, in the case of two-axis longitudinal drives, can be arranged in a floating manner in order to cushion the drive masses, the drive axle 8 shown in FIG. 3, in which the previous reference numerals also correspond to parts corresponding to the previous embodiments to be kept.

Bei dem in Fig. 3 dargestellten Ausführungsbeispiel sind die Großräder 26 nicht auf den Wellenabschnitten 6 bzw. 7 der Treibachse 8 selbst gelagert, sondern jeweils auf einer Hohlwelle 29 bzw. 30, welche die Treibachse 8 mit Spiel umgibt. Die Hohlwelle 29 trägt einen Ansatz 31 geringeren Durchmessers, der in das Innere der Hohlwelle 30 hineinragt und dort mit Lagern 32 gelagert ist. Diese Lager 32 sind als trockengeschmierte wartungsfreie Gleitlager ausgebildet, da auch die Relativdrehzahl zwischen beiden Hohlwellen 29 bzw. 30 sehr gering ist. Außerdem ist jede Hohlwelle 29 bzw. 30 über eine zentrierende und elastische Kupplung 33 mit dem zugehörigen Wellenabschnitt 6 bzw. 7 verbunden. Die Kupplung 33 ist als Gummiringfederkupplung dargestellt, es sind aber auch andere elastische Kupplungen, wie z. B. Lenkerkupplungen, geeignet. Infolge des Vorhandenseins dieser Kupplungen 33 ist die Masse der Hohlwellen 29, 30 mit dem nicht dargestellten Antriebsteilen gegenüber der Treibachse 8 mit den Treibrädern 11 und 12 primär abgefedert.In the embodiment shown in FIG. 3, the large wheels 26 are not mounted on the shaft sections 6 or 7 of the drive shaft 8 themselves, but rather on a hollow shaft 29 or 30, which surrounds the drive shaft 8 with play. The hollow shaft 29 carries a shoulder 31 of smaller diameter, which projects into the interior of the hollow shaft 30 and is supported there with bearings 32. These bearings 32 are designed as dry-lubricated, maintenance-free plain bearings, since the relative speed between the two hollow shafts 29 and 30 is also very low. In addition, each hollow shaft 29 or 30 is connected to the associated shaft section 6 or 7 via a centering and elastic coupling 33. The clutch 33 is shown as a rubber ring spring clutch, but there are also other flexible couplings, such as. B. handlebar couplings. As a result of the presence of these clutches 33, the mass of the hollow shafts 29, 30 with the drive parts, not shown, is primarily cushioned with respect to the drive axle 8 with the drive wheels 11 and 12.
