Description

Die Erfindung bezieht sich auf ein schienengebundenes elektrisches Triebfahrzeug, bei welchem ein in Fahrzeuglängsrichtung angeordneter elektrischer Fahrmotor zwei Treibachsen antreibt, indem jede Treibachse über eine elastische Kupplung, eine sie umgebende Kardanhohlwelle und eine weitere elastische Kupplung mit dem GroBrad eines Getriebes verbunden ist, dessen Ritzel von einem Ende der Läuferwelle des Fahrmotors angetrieben ist, wobei Fahrmotor und Getriebe federnd im Fahr- bzw. Drehgestell aufgehängt sind.The invention relates to a rail-bound electric traction vehicle, in which an electric traction motor arranged in the longitudinal direction of the vehicle drives two drive axles, in that each drive axle is connected via an elastic coupling, a cardan hollow shaft surrounding it and a further elastic coupling to the large wheel of a transmission, the pinion of which one end of the rotor shaft of the traction motor is driven, the traction motor and transmission being resiliently suspended in the bogie or bogie.

Ein derartiges Triebfahrzeug ist aus der US-PS 36 26 862 bekannt. Zur federnden Aufhängung des Fahrmotors und der Getriebegehäuse dienen bei diesem bekannten Triebfahrzeug jeweils Gummifedern, die zwischen einer mit dem Fahr- bzw. Drehgestell verbundenen Platte und einer mit dem Fahrmotor bzw. dem Getriebegehäuse verbundenen Platte angeordnet sind. Dadurch wird eine Entkopplung der Massen-des Fahrmotors und der Getriebe von dem Fahr- bzw. Drehgestell erzielt und eine Verringerung der ungefederten Massen. Diese Aufhängung bedingt aber einen verhältnismäßig großen Durchmesser der Kardanhohlwelle, um die zwischen Fahr- bzw. Drehgestell und der Treibachse möglichen Federwege aufzunehmen. Dies verringert aber den Platz für den elektrischen Fahrmotor.Such a locomotive is known from US-PS 36 26 862. For resilient suspension of the traction motor and the gear housing are in this known traction unit rubber springs each disposed between a to the accelerator - are arranged and connected bogie plate and connected to the driving motor or the gear box plate. This decouples the mass of the vehicle motors and the transmission from the bogie and bogie and a reduction in unsprung masses. However, this suspension requires a relatively large diameter of the hollow cardan shaft in order to absorb the spring travel possible between the chassis or bogie and the drive axle. However, this reduces the space for the electric drive motor.

Der Erfindung liegt die Aufgabe zugrunde, das Fahrverhalten des Triebfahrzeuges durch eine größere sekundärgefederte Masse zu verbessern, ohne daß derJNirdas Antriebsaggregat und dem Fahrmotor zur Verfügung stehende Raum zu stark eingeengt wird.The invention has for its object to improve the driving behavior of the locomotive by a larger secondary spring mass, without the space available to the drive unit and the drive motor being restricted too much.

Zur Lösung dieser Aufgabe sind gemäß der Erfindung bei einem Triebfahrzeug der eingangs beschriebenen Art als Aufhängung auf jeder Seite des Fahrmotors zwei gelenkig befestigte Pendel vorgesehen, die ein Federdämpferglied enthalten und deren zum Fahrmotor bzw. zum aus Fahrmotor und Getriebe_gebildeten Antriebsaggregat führender Gelenkpunkt unterhalb der Mittellinien liegt, und außerdem sind zumindest je zwei in Längsrichtung liegende Lenker zwischen Fahrmotor bzw. Antriebsaggregat und dem Fahr- bzw. Drehgestell angeordnet.To solve this problem, according to the invention, in a traction vehicle of the type described in the introduction, two articulated pendulums are provided as a suspension on each side of the traction motor, which contain a spring damper member and whose articulation point leading to the traction motor or to the drive unit formed from the traction motor and transmission is below the center lines , and in addition, at least two longitudinal links are arranged between the drive motor or drive unit and the bogie or bogie.

Durch die Aufhängung an Pendeln mit Federdämpfergliedern, die große Wege zulassen, aber eine Resonanzsshwingung unterbinden, können die von vertikalen Schienenunebenheiten erzeugten Stöße weitgehend abgebaut werden. Dadurch sind bei relativ schlechten Gleisen größere Fahrgeschwindigkeiten möglich. Die Pendel mit ihren tiefliegenden Befestigungspunkten am Fahrmotor bzw. Antriebsaggregat können große Durchfederungswege aufnehmen, so daß die Kardanhohlwelle ihrerseits nur geringe Wege ausgleichen muß und ihr Durchmesser kann entsprechend klein gewählt werden. Infolge der Aufhängung des Fahrmotors und Getriebes bzw. des Antriebsaggregates über Pendeln mit einem Federdämpferglied im Fahr- bzw. Drehgestell erhält das Triebfahrzeug zwei voneinander unabhängig schwingende Sekundärmassen, und zwar zusätzlich zum Wagenkasten den Fahrmotor mit Getrieben bzw. das Antriebsaggregat. Es wird ein sehr stabiles Fahrverhalten erzielt, was noch durch die als Stabilisatoren in Längsrichtung wirkenden horizontal liegenden Lenker, die vertikale Bewegungen zulassen, unterstützt wird.Due to the suspension on pendulums with spring damper links that allow long distances but prevent resonance vibrations, the shocks generated by vertical rail unevenness can be largely reduced. This means that higher speeds are possible on relatively poor tracks. The pendulum with its low-lying attachment points on the drive motor or drive unit can accommodate large deflection paths, so that the cardan hollow shaft in turn only has to compensate for small distances and its diameter can be chosen to be correspondingly small. As a result of the suspension of the traction motor and gearbox or the drive unit via oscillation with a spring damper member in the bogie or bogie, the locomotive receives two independently vibrating secondary masses, in addition to the car body, the traction motor with gears or the drive unit. A very stable driving behavior is achieved, which is further supported by the horizontally lying handlebars acting as stabilizers in the longitudinal direction, which allow vertical movements.

Im folgenden sei die Erfindung noch anhand des in der Zeichnung dargestellten Ausführungsbeispiels näher beschrieben. Diese zeigt in Fig. 1, teilweise geschnitten, eine schematische Draufsicht auf das Drehgestell eines elektrischen Triebfahrzeuges mit dem darin aufgehängten Antriebsaggregat.In the following, the invention will be described 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 traction vehicle with the drive unit suspended therein.

Fig. 2 zeigt einen Längsschnitt entlang der Schnittlinie II-II in Fig. 1 und Fig. 3 ebenfalls einen Schnitt entlang der Linie III-III in Fig. 2, wobei allerdings der Fahr- - motor ungeschnittenund nur schematisch dargestellt ist.Fig. 2 shows a longitudinal section along the section line II-II in Fig. 1 and Fig. 3 also a section along the line III-III in Fig. 2, but the drive motor is shown uncut and only schematically.

Bei einem schienengebundenen Triebfahrzeug, das insbesondere für den Nahverkehr eingesetzt wird, werden jeweils zwei Treibachsen 1 von einem quer zwischen ihnen in Längsrichtung des Triebfahrzeuges angeordneten elektrischen Fahrmotor 2 angetrieben. Dazu ist jede Treibachse 1 über eine aus Lenkern 3 bestehenden elastischen Kupplung, eine die Treibachse 1 mit Spiel umgebenden Kardanhohlwelle 4 und eine weitere aus einer Gummiringfeder 5 gebildeten elastischen Kupplung mit einer die Kardanhohlwelle 4 umgebenden Hohlwelle 6 verbunden,die das nicht dargestellte GroBrad eines Winkelgetriebes trägt. Das Ritzel dieses Getriebes ist jeweils von einem Ende der Läuferwelle des Fahrmotors 2 angetrieben.In the case of a rail-bound locomotive which is used in particular for local traffic, two driving axles 1 are each driven by an electric traction motor 2 arranged transversely between them in the longitudinal direction of the locomotive. For this purpose, each drive axle 1 via an elastic coupling consisting of links 3 the drive shaft 1 with clearance surrounding the cardan hollow shaft 4 and a further elastic coupling formed from a rubber ring spring 5 connected to a hollow shaft 6 surrounding the cardan hollow shaft 4, which carries the large gear, not shown, of an angular gear. The pinion of this transmission is driven by one end of the rotor shaft of the traction motor 2.

Der elektrische Fahrmotor 2 ist mit den an jeder Stirnseite liegenden Getriebegehäusen 7 zu einem Antriebsaggregat 8 zusammengefaßt. Dieses ist über zwei auf jeder Seite des Fahrmotors 2 gelenkig befestigte Pendel 9 im Drehgestell 10 aufgehängt. Dazu sind die Pendel 9 jeweils über einen Gelenkpunkt 11 am Drehgestell 10 und einem Gelenkpunkt 12 unterhalb der Mittellinie der Treibachse 1 am Fahrmotor 2 befestigt, wobei die Pendel 9 schräg zur Treibachse 1 liegen. Die Gelenkpunkte 11 und 12 sind jeweils mit einer Gummieinlage versehen, um den Verschleiß zu verringern. Jedes Pendel 9 enthält ein Federdämpferglied 13.The electric traction motor 2 is combined with the transmission housings 7 on each end face to form a drive unit 8. This is suspended in the bogie 10 via two pendulums 9 articulated on each side of the driving motor 2. For this purpose, the pendulums 9 are each fastened to the bogie 10 via a pivot point 11 on the bogie 10 and a pivot point 12 below the center line of the driving axis 1, the pendulums 9 being inclined to the driving axis 1. The hinge points 11 and 12 are each provided with a rubber insert in order to reduce wear. Each pendulum 9 contains a spring damper member 13.

Durch diese federnde Aufhängung des Antriebsaggregates 8 im Drehgestell 10 über Pendel 9 ist aus der Masse des Antriebsaggregates 8 eine sekundär gefederte Masse geworden. Diese Verringerung der ungefederten Massen verbessert das Fahrverhalten des Triebfahrzeuges. Die Pendel 9 nehmen große Federwege auf und bauen daher an den Treibachsen 1 auftretende Stöße weitgehend ab. Dadurch braucht die Kardanhohlwelle 4, welche die Treibachse 1 umgibt, nur kleine Federwege aufzunehmen und ihr Durchmesser kann entsprechend klein gewählt werden. Es steht dadurch genügend Raum für das Antriebsaggregat 8 zur Verfügung.Due to this resilient suspension of the drive unit 8 in the bogie 10 via pendulum 9, the mass of the drive unit 8 has become a secondary spring mass. This reduction in unsprung masses improves the driving behavior of the locomotive. The pendulums 9 take up long spring travel and therefore largely reduce shocks occurring on the driving axles 1. As a result, the hollow cardan shaft 4, which surrounds the drive axle 1, only needs to absorb small spring travel and its diameter can be chosen to be correspondingly small. As a result, there is enough space available for the drive unit 8.

Bei einem derartig aufgehängten Antriebsaggregat 8 können außerdem keine Resonanzschwingungen auftreten, weil die Pendel 9 Federdämpferglieder 13 enthalten. Zusätzlich sind auf jeder Seite des Fahrmotors 2 zwei in Längsrichtung liegende Lenker 14 zwischen dem Antriebsaggregat 8 und dem Drehgestell 10 angeordnet. Diese stabilisieren das Antriebsaggregat in Längsrichtung, behindern aber vertikale Bewegungen nicht.In a drive unit 8 suspended in this way, no resonance vibrations can occur because the Pendulum 9 spring damper 13 included. In addition, two longitudinal links 14 are arranged on each side of the drive motor 2 between the drive unit 8 and the bogie 10. These stabilize the drive unit in the longitudinal direction, but do not hinder vertical movements.
