Abstract

1. Railborn electric motor vehicle, wherein an electric traction motor (3) lying parallel with the drive axle (2), drives the latter in that the drive axle is connected to the greater wheel of a gear by means of an elastic coupling, a Cardan hollow shaft (7) surrounding the latter and a further elastic coupling, the pinion of which greater wheel is driven by the rotor shaft directly or by means of a further gear, where the traction motor is arranged like a pendulum in the carriage body via connecting rods (9), characterised in that a levelling arrangement (15) is accommodated at the connecting rods (9).

Description

Die Erfindung bezieht sich auf ein schienengebundenes elektrisches Triebfahrzeug, bei welchem ein parallel zur Treibachse liegender elektrischer Fahrmotor diese antreibt, indem die Treibachse über eine elastische Kupplung, eine sie umgebende Kardanhohlwelle und eine weitere elastische Kupplung mit dem Großrad eines Getriebes verbunden ist, dessen Ritzel von der Läuferwelle direkt oder über ein weiteres Getriebe angetrieben ist, wobei der Fahrmotor im Wagenkasten über Lenker pendelnd aufgehängt ist.The invention relates to a rail-bound electric traction vehicle, in which an electric traction motor lying parallel to the drive axle drives the latter by connecting the drive axle to the large wheel of a transmission, the pinion of which is connected via an elastic coupling, a cardan hollow shaft surrounding it and a further elastic coupling the rotor shaft is driven directly or via a further gearbox, with the traction motor suspended in the car body via the handlebars.

Ein derartiges Triebfahrzeug ist aus der DE-A-26 50 035 bekannt. Die pendelnde Aufhängung des querliegenden Fahrmotors besteht bei dieser bekannten Anordnung aus drei starren Lenkern, die auf beiden Seiten des Fahrmotors angeordnet sind, und deren einer Gelenkpunkt am Wagenkasten und deren anderer Gelenkpunkt an einem unterhalb der Mittellinie der Treibachse liegenden Auge des Fahrmotorgehäuses angeordnet ist. Die Gelenkpunkte sind als Gummimetallverbundgelenke ausgebildet, damit Verschleiß vermieden wird. Da die möglichen Federwege zwischen der Treibachse und dem Wagenkasten sehr groß sind, insbesondere weil sich der Wagenkasten in Abhängigkeit vom Wagengewicht, d. h. unter Umständen von der Zahl der Fahrgäste, verlagert, ist bei dem bekannten Triebfahrzeug der Durchmesser der zwischen dem Ritzel des Fahrmotors und der Treibachse angeordneten, die Treibachse mit Spiel umgebende Kardanhohlwelle verhältnismäßig groß, um sämtliche Federwege bei allen Geschwindigkeiten aufzunehmen. Dies hat aber den Nachteil, daß der Abstand zwischen Treibachse und Fahrmotor, d. h. die Motorzentrale, entsprechend groß wird, so daß infolge des dadurch erforderlichen ebenfalls entsprechend großen Großrades Schwierigkeiten hinsichtlich der Bodenfreiheit auftreten.Such a locomotive is known from DE-A-26 50 035. The oscillating suspension of the transverse drive motor consists in this known arrangement of three rigid links, which are arranged on both sides of the drive motor, and one articulation point on the car body and the other articulation point is arranged on an eye of the drive motor housing below the center line of the drive axis. The hinge points are designed as rubber-metal composite joints so that wear is avoided. Since the possible spring travel between the drive axle and the car body is very large, especially because the car body is dependent on the car weight, i.e. H. possibly shifted from the number of passengers, the diameter of the arranged between the pinion of the drive motor and the drive axle, the drive axle with play surrounding the hollow shaft is relatively large in the known traction vehicle in order to absorb all travel at all speeds. However, this has the disadvantage that the distance between the drive axle and the drive motor, i. H. the engine control center, is correspondingly large, so that difficulties in terms of ground clearance occur due to the large wheel that is also required.

Der Erfindung liegt die Aufgabe zugrunde, diese Schwierigkeiten bei einer pendelnden Aufhängung des querliegenden Fahrmotors im Wagenkasten zu vermeiden.The invention has for its object to avoid these difficulties with an oscillating suspension of the transverse drive motor in the car body.

Zur Lösung dieser Aufgabe ist bei einem Triebfahrzeug der eingangs beschriebenen Art gemäß der Erfindung in den Lenkern eine Niveauregelung untergebracht. Kleine Federwege werden dann von dem Kardanantrieb aufgenommen, während größere Federwege von der Niveauregelung ausgeglichen werden. Der Durchmesser der Kardanhohlwelle kann dadurch wesentlich kleiner gehalten werden, so daß genügend Platz zur Unterbringung eines Fahrmotors großer Leistung für hohe Fahrgeschwindigkeiten bei kleiner Motorzentrale verbleibt.To solve this problem, a level control is accommodated in the handlebars of a traction vehicle of the type described in the invention. Small spring travel is then taken up by the cardan drive, while larger spring travel is compensated for by the level control. The diameter of the cardan hollow shaft can thereby be kept considerably smaller, so that there is enough space to accommodate a large-capacity traction motor for high driving speeds with a small motor center.

Es empfiehlt sich, die Niveauregelung mit einer Dämpfung zu versehen, damit sich der Antrieb in seinen Pendelbewegungen schwingungsmäßig nicht aufschaukelt.It is advisable to provide the level control with damping so that the drive does not vibrate in its oscillating movements.

Die gemäß der Erfindung ausgebildete Aufhängung des Fahrmotors im Wagenkasten kann mit Vorteil sowohl bei einem Einzelachsantrieb mit Kardanhohlwelle als auch bei einem Einzelachsantrieb mit Zwischengetriebe und Kardanhohlwelle angewendet werden. Zur Ersparnis von Aufhängeelementen empfiehlt es sich, bei einem Drehgestell mit zwei darin untergebrachten Einzelachsantrieben mit Quermotor die Fahrmotoren zweier benachbarter Treibachsen in an sich bekannter Weise über einen Zwischenträger starr miteinander zu verbinden und dann auf jeder Seite dieses Zwischenträgers einen Lenker mit Niveauregelung angreifen zu lassen. Darüber hinaus werden durch die Verbindung über den Zwischenträger die beiden Einzelmassen der Fahrmotoren zu einer Gesamtmasse vereinigt. Das Verhalten dieser Gesamtmasse in Bezug auf Stöße ist wegen der doppelten Trägheit günstiger, was den Fahrkomfort verbessert.The suspension of the traction motor in the vehicle body designed according to the invention can advantageously be used both with a single-axis drive with a cardan hollow shaft and with a single-axis drive with an intermediate gear and a cardan hollow shaft. To save on suspension elements, it is advisable to rigidly connect the traction motors of two adjacent drive axles to one another in a manner known per se in a known manner in a bogie with two single-axis drives with a transverse motor and then to have a handlebar with level control engage on each side of this intermediate support. In addition, the two individual masses of the traction motors are combined to form a total mass by the connection via the intermediate carrier. The behavior of this total mass in relation to shocks is more favorable because of the double inertia, which improves driving comfort.

Im folgenden sei die Erfindung noch anhand des in der Zeichnung dargestellten Ausführungsbeispieles näher erläutert. Diese zeigt in Fig. 1, teilweise geschnitten, eine schematische Draufsicht auf das Drehgestell eines elektrischen Triebfahrzeuges, von unterhalb des Wagenkastens gesehen. Fig.2 zeigt einen Längsschnitt entlang der Schnittlinie 11-11 in Fig. 1 und Fig. 3 ebenfalls einen Schnitt entlang der Linie 111-111 in Fig. 2, wobei die hinter der ersten Treibachse liegenden Pendel nicht eingezeichnet sind.In the following the invention will be explained in more detail with reference to the embodiment shown in the drawing. 1 shows, partially in section, a schematic plan view of the bogie of an electric locomotive, seen from below the car body. 2 shows a longitudinal section along the section line 11-11 in FIG. 1 and FIG. 3 also shows a section along the line 111-111 in FIG. 2, the pendulums lying behind the first driving axis not being shown.

Bei einem schienengebundenen Triebfahrzeug, das für den Nah- und Fernverkehr, insbesondere bei hohen Fahrgeschwindigkeiten, eingesetzt werden kann, sind jeweils die beiden innerhalb eines Drehgestells 1 liegenden Treibachsen 2 jeweils von einem parallel zu ihnen angeordneten elektrischen Fahrmotor angetrieben. Dazu ist jede Treibachse 2 über eine aus Lenkern gebildeten elastische Kupplung, eine die Treibachse 2 mit Spiel umgebende Kardanhohlwelle 5 und eine weitere aus einer Gummiringfeder 6 gebildeten elastischen Kupplung mit einer die Kardanhohlwelle 5 umgebenden Hohlwelle 7 verbunden, die das nicht dargestellte Großrad eines Stirnradgetriebes trägt, in welches das Ritzel des Fahrmotors 3 eingreift.In the case of a rail-bound locomotive that can be used for local and long-distance traffic, especially at high speeds, the two drive axles 2 located within a bogie 1 are each driven by an electric drive motor arranged parallel to them. For this purpose, each drive axle 2 is connected via an elastic coupling formed by links, a cardan hollow shaft 5 surrounding the drive axle 2 with play and a further elastic coupling formed from a rubber ring spring 6 with a hollow shaft 7 surrounding the cardan hollow shaft 5, which carries the large gear (not shown) of a spur gear , in which the pinion of the drive motor 3 engages.

Die elektrischen Fahrmotoren 3 der beiden innerhalb des Drehgestells 1 liegenden Treibachsen 2 sind über einen Zwischenträger8 starr miteinander verbunden.The electric traction motors 3 of the two drive axles 2 located within the bogie 1 are rigidly connected to one another via an intermediate carrier 8.

Beide elektrische Fahrmotoren 3 sind über Lenker 9 im Wagenkasten 10 aufgehängt. Zwei Lenker 9 greifen dazu zwischen der Treibachse 2 und der Stirnseite des Drehgestells 1 liegend mit ihrem unteren Gelenkpunkt 12 am Getriebegehäuse 13 unterhalb der Mittellinie der Treibachse 2 an, die beiden anderen Lenker 9 liegen auf beiden Seiten des Fahrmotors 3 und greifen mit ihrem unteren Gelenkpunkt 14 am starren Zwischenträger 8 an. Außerdem enthält jeder Lenker 9 eine Niveauregelung 15. Diese kann in an sich bekannter Weise pneumatisch oder hydraulisch ausgebildet sein. Die Niveauregelung 15 gleicht die zwischen den Wagenkasten 10 und den Fahrmotoren 3 möglichen großen Federwege aus. Daher braucht die Kardanhohlwelle nur einen verhältnismäßig kleinen Durchmesser aufzuweisen, weil sie nur verhältnismäßig kleine Federwege aufzunehmen hat.Both electric traction motors 3 are suspended via handlebars 9 in the body 10. Two links 9 engage between the driving axle 2 and the front of the bogie 1 lying with their lower pivot point 12 on the gear housing 13 below the center line of the driving axis 2, the other two links 9 lie on both sides of the drive motor 3 and engage with their lower pivot point 14 on the rigid intermediate support 8. In addition, each link 9 contains a level control 15. This can be designed pneumatically or hydraulically in a manner known per se. The level rain 15 balances the large spring travel possible between the body 10 and the drive motors 3. The cardan hollow shaft therefore only has to have a relatively small diameter because it has to absorb only relatively small spring travel.

Für die Längsstabilisation sind beidseitig je ein Lenker 16 von den Fahrmotoren 3 bzw. vom Zwischenträger 8 zum Drehgestell 1 horizontal angeordnet.For the longitudinal stabilization, a link 16 from the traction motors 3 or from the intermediate carrier 8 to the bogie 1 is arranged horizontally on both sides.
