Description
Die Erfindung bezieht sich auf eine Antriebsvorrichtung zum Einleiten einer Antriebsbewegung in eine Radsatzwelle eines Schienenfahrzeugs.The invention relates to a drive device for initiating a drive movement in a wheelset shaft of a rail vehicle.
Die Erfindung bezieht sich auch auf ein Schienenfahrzeug mit mindestens einer solchen Antriebsvorrichtung.The invention also relates to a rail vehicle with at least one such drive device.
Aus dem Stand der Technik sind für dieselelektrische oder elektrische Schienenfahrzeuge mit Höchstgeschwindigkeiten bis 160 km/h sowohl vollabgefederte als auch teilabgefederte und unabgefederte Antriebsvorrichtungen bekannt. Schienenfahrzeuge mit Höchstgeschwindigkeiten über 160 km/h weisen gemäß dem Stand der Technik bei Triebköpfen und Lokomotiven mit höheren Leistungen (über 4000kW) jedoch nur vollabgefederte Antriebsvorrichtungen auf. Güterzüge mit geringen Höchstgeschwindigkeiten und hohen Anfahrzugkräften sind oftmals mit einem einfachen Tatzlagerantrieb ohne Kupplung ausgestattet, wobei der Fahrmotor robust und schwer ausgebildet ist und sich über das Getriebe an der Radsatzwelle über sogenannte Tatzlager abstützt. Bei höheren Geschwindigkeiten wirken sich Stöße, welche durch Unebenheiten auf den Schienen über die Räder auf die Radsatzwellen übertragen werden, unvorteilhaft auf diese Antriebsvorrichtung aus. Zusätzlich sind die Belastungen für den Gleisbau durch die hohen unabgefederten Massen sehr hoch. Deshalb werden gemäß dem Stand der Technik Schienenfahrzeuge für Höchstgeschwindigkeiten über 160km/h, insbesondere Triebköpfe und Lokomotiven, mit vollabgefederten Antriebsvorrichtungen, beispielsweise mit Kardan-Hohlwellenantrieben, ausgestattet, die komplex aufgebaut und schwer sind.Both fully sprung and partially sprung and unsprung drive devices are known from the prior art for diesel-electric or electric rail vehicles with maximum speeds of up to 160 km / h. However, rail vehicles with maximum speeds in excess of 160 km / h, according to the state of the art in power cars and locomotives with higher power (over 4000kW) but only fully sprung drive devices. Freight trains with low speeds and high Anfahrzugkräften are often equipped with a simple Tatzlagerantrieb without clutch, the traction motor is robust and heavy and is supported via the gearbox on the axle via so-called Tatzlager. At higher speeds impact, which are transmitted by unevenness on the rails on the wheels on the wheelset, unfavorable effect on this drive device. In addition, the loads for the track construction by the high unsprung masses are very high. Therefore, according to the prior art rail vehicles for maximum speeds over 160km / h, especially power cars and locomotives, equipped with vollabsprederten drive devices, such as with cardan hollow shaft drives, which are complex and heavy.
Der Erfindung liegt die Aufgabe zugrunde eine besonders einfach aufgebaute und ein geringes Gewicht aufweisende Antriebsvorrichtung für ein Hochleistungs-Schienenfahrzeug insbesondere für Triebköpfe und Lokomotiven für den Geschwindigkeitsbereich oberhalb 160 km/h zu schaffen, die gleichzeitig für schweren Güterverkehr mit niedriger Geschwindigkeit und hohen Zugkräften und hoher Leistung wirtschaftlich eingesetzt werden kann.The invention has for its object to provide a particularly simple design and low-weight drive device for a high-performance rail vehicle, especially for power cars and locomotives for the speed range above 160 km / h, at the same time for heavy goods traffic with low speed and high tensile forces and high Performance can be used economically.
Die Aufgabe wird erfindungsgemäß durch eine Antriebsvorrichtung zum Einleiten einer Antriebsbewegung in eine Radsatzwelle eines Schienenfahrzeugs,
- mit einem elektrischen Fahrmotor
- einem Getriebe,
- einer zwischen dem Fahrmotor und dem Getriebe angeordneten Kupplung, die Kupplungsbauteile aufweist, und
- Haltemitteln, die den Fahrmotor voll abgefedert, die Antriebsvorrichtung insgesamt jedoch teilabgefedert am Schienenfahrzeug halten, wobei
- with an electric traction motor
- a gear,
- a clutch arranged between the traction motor and the transmission, which has clutch components, and
- Holding means which fully cushioned the traction motor, but keep the drive device as a whole partially sprung on the rail vehicle, wherein
Die Erfindung sieht vor, dass zwischen dem Getriebe und dem Fahrmotor eine Kupplung, welche die Drehung einer Motorwelle des Fahrmotors auf das Getriebe überträgt, angeordnet ist. Das Getriebe ist so am Fahrmotor abgestützt, dass Relativbewegungen von Kupplungsbauteilen in Kupplungsebenen der Kupplung reduziert sind um eine einfache und kompakte Bauweise der Kupplung realisieren zu können Dem liegt die Erkenntnis zugrunde, dass der voll abgefederte Fahrmotor bei Geschwindigkeiten über 160km/h auch dann ausreichend vor Stößen gesichert ist, wenn sich am Fahrmotor ein nur teilweise abgefedertes oder unabgefedertes Getriebe abstützt. Dies ermöglicht eine leichte Ausführung des Fahrmotors gegenüber dem Fahrmotor beim Tatzlagerantrieb.The invention provides that between the transmission and the traction motor, a clutch which transmits the rotation of a motor shaft of the traction motor to the transmission, is arranged. The gearbox is supported on the traction motor in such a way that relative movements of clutch components are reduced in the coupling planes in order to realize a simple and compact design of the clutch. This is based on the finding that the fully sprung traction motor at speeds of more than 160 km / h is sufficient Bumps is secured when the traction motor is only partially cushioned or unsupported gearbox supported. This allows easy execution of the drive motor relative to the traction motor when Tatzlagerantrieb.
Mit dem Passus teilabgefedertes Bauteil ist im Rahmen der vorliegenden Erfindung ein Bauteil bezeichnet, welches mit Haltemitteln an einem Widerlager befestigbar ist, wobei ein Teil der Haltemittel Federelemente umfasst und ein weiterer Teil als ungefederte Haltemittel realisiert ist. Dabei weisen die Haltemittel mit den Federelementen eine Federkennlinie auf, welche den Zusammenhang zwischen Rückstellkraft und Federweg darstellt. Stöße, welche von dem Widerlager über die Haltemittel mit den Federelementen auf das Getriebe übertragen werden, sind hierdurch federnd aufgenommen und über den Federelementen immanente Dämpfungseffekte abgesenkt.
Als Beispiel für ein unabgefedertes Getriebe sei ein achsreitendes Getriebe genannt, welches ein die Radsatzwelle umfassendes Großrad aufweist, das mit der Radsatzwelle drehfest verbunden ist. Die erfindungsgemäße Antriebsvorrichtung weist ein teilweise abgefedertes oder unabgefedertes Getriebe auf, welches im Gegensatz zu den Getrieben einer vollabgefederten Antriebsvorrichtung einfacher aufgebaut ist. Durch den einfacheren Aufbau kann Gewicht der Antriebsvorrichtung eingespart werden. Zudem ist eine höhere Wartungsfreiheit der Antriebsvorrichtung gewährleistet. Das Getriebe kann beispielsweise so am Schienenfahrzeug befestigbar sein, dass ein Teil des Getriebegewichtes an der Radsatzwelle und/oder am Drehgestell und/oder Fahrwerk des Schienenfahrzeugs abgestützt ist. Beispielsweise könnte das Getriebe unabgefedert mit der Radsatzwelle und/oder mit dem Drehgestell verbunden sein. Wesentlich hierbei ist, dass das Getriebe am Fahrmotor abgestützt ist, so dass Relativbewegungen von Kupplungsbauteilen in Kupplungsebenen der Kupplung reduziert sind. Je nach Ausgestaltung der Kupplung können Richtungen in den Kupplungsebenen existieren, entlang denen eine Relativbewegung von Kupplungsbauteilen in den Kupplungsebenen keinen nachteiligen Einfluss auf die Kupplungseigenschaften der Kupplung hat. Um ein sicheres Kuppeln der Kupplungsbauteile in den Kupplungsebenen zu gewährleisten, ist die Abstützung des Getriebes am Fahrmotor derart ausgestaltet, dass zumindest die Relativbewegung von Kupplungsbauteilen in Kupplungsebenen der Kupplung reduziert sind, welche ein ordnungsgemäßes Ineinandergreifen der Kupplungsbauteile behindern würden. Hierzu kann beispielsweise das Getriebe am Fahrmotor angelenkt sein.In the context of the present invention, the component partially sprung component designates a component which can be fastened to an abutment with holding means, wherein a part of the holding means comprises spring elements and a further part is realized as unsprung holding means. In this case, the holding means with the spring elements on a spring characteristic, which represents the relationship between restoring force and travel. Shocks, which are transmitted from the abutment on the holding means with the spring elements on the gear, are thereby resiliently received and lowered over the spring elements immanent damping effects.
As an example of a non-sprung transmission is called an achsreitendes gear, which has a large wheelset comprehensive gear, which is rotatably connected to the wheelset. The drive device according to the invention has a partially sprung or unsprung transmission, which is constructed simpler, in contrast to the gears of a fully sprung drive device. Due to the simpler structure weight of the drive device can be saved. In addition, a higher maintenance freedom of the drive device is ensured. The transmission may for example be fastened to the rail vehicle such that a part of the transmission weight is supported on the wheel set shaft and / or on the bogie and / or chassis of the rail vehicle. For example, the transmission could be unsupported connected to the axle and / or to the bogie. It is essential here that the transmission is supported on the traction motor, so that relative movements of coupling components in clutch planes of the clutch are reduced. Depending on the design The clutch may have directions in the clutch planes along which relative movement of clutch components in the clutch planes does not adversely affect the clutch characteristics of the clutch. In order to ensure a safe coupling of the coupling components in the coupling planes, the support of the gearbox on the traction motor is designed such that at least the relative movement of coupling components are reduced in coupling levels of the coupling, which would hinder a proper engagement of the coupling components. For this purpose, for example, the transmission may be articulated on the traction motor.
Es kann vorteilhaft vorgesehen sein, dass die Antriebsvorrichtung für Fahrgeschwindigkeiten des Schienenfahrzeugs über 160 km/h ausgelegt ist.It can be advantageously provided that the drive device is designed for travel speeds of the rail vehicle over 160 km / h.
Die erfindungsgemäße Antriebsvorrichtung ist sowohl bei langsamen Schienenfahrzeugen, beispielsweise Güterzügen, vorteilhaft einsetzbar als auch bei schnell fahrenden Hochleistungsschienenfahrzeugen. Durch die einfache und leichte Bauweise ist sie besonders vorteilhaft für Schienenfahrzeuge mit Höchstgeschwindigkeiten über 160km/h einsetzbar.The drive device according to the invention can be used advantageously both in slow-moving rail vehicles, for example freight trains, and in high-speed rail vehicles traveling at high speeds. Due to the simple and lightweight design, it is particularly advantageous for rail vehicles with maximum speeds over 160km / h used.
Es kann auch als vorteilhaft angesehen werden, dass die Antriebsvorrichtung für Anfahrzugkräfte von mindestens 250 kN, insbesondere mindestens 280 kN, ausgelegt ist.It can also be considered advantageous that the drive device for Anfahrzugkräfte of at least 250 kN, in particular at least 280 kN, is designed.
Dies ermöglicht die Schaffung einer Universallokomotive mit besonders geringen Achslasten.This allows the creation of a universal locomotive with very low axle loads.
Weiter kann vorteilhaft vorgesehen sein, dass die Haltemittel Motorhaltemittel zum vollabgefederten Halten des Fahrmotors am Schienenfahrzeug aufweisen.Furthermore, it can be advantageously provided that the holding means have motor holding means for fully spring-loaded holding of the traction motor on the rail vehicle.

Mit anderen Worten ist der Motor quer zur Fahrtrichtung des Schienenfahrzeugs an diesem anordnenbar. Beispielsweise kann der Fahrmotor quer im Drehgestell anordnenbar sein. Dies ermöglicht eine kompakte Bauweise der Antriebsvorrichtung.In other words, the motor can be arranged transversely to the direction of travel of the rail vehicle. For example, the traction motor can be arranged transversely in the bogie. This allows a compact design of the drive device.
Vorteilhafterweise kann weiter vorgesehen sein, dass die Motorhaltemittel zum querelastischen Befestigen des Fahrmotors eingerichtet sind.Advantageously, it may further be provided that the motor holding means are arranged for transversely elastic fastening of the drive motor.
Es kann auch als vorteilhaft angesehen werden, dass die Haltemittel Befestigungsmittel zum nicht federnden Befestigen am Schienenfahrzeug umfassen.It may also be considered advantageous that the retaining means comprise fastening means for non-resilient attachment to the rail vehicle.
Da es erfindungsgemäß ausreichend ist für den Geschwindigkeitsbereich oberhalb von 160 km/h nur den Fahrmotor voll abgefedert am Schienenfahrzeug zu befestigen, sind zum Halten der Antriebsvorrichtung auch Befestigungsmittel zum nicht federnden Befestigen dieser am Schienenfahrzeug angeordnet. Diese weisen einen einfacheren Aufbau auf als federnde Haltemittel.Since it is sufficient according to the invention for the speed range above 160 km / h only to fully secure the traction motor cushioned on the rail vehicle, fastening means for non-resilient mounting these are arranged on the rail vehicle for holding the drive device. These have a simpler structure than resilient holding means.
Weiter kann vorteilhaft vorgesehen sein, dass die Befestigungsmittel Getriebebefestigungsmittel zum Befestigen des Getriebes auf der Radsatzwelle umfassen.Furthermore, it can be advantageously provided that the fastening means comprise gear fastening means for fastening the gearbox to the wheelset shaft.
Die Getriebebefestigungsmittel können das Getriebe beispielsweise drehfest mit der Radsatzwelle verbinden, so dass das Getriebe achsreitend ausgebildet ist. Ein derartiges Getriebe ist besonders einfach aufgebaut und weist ein geringes Gewicht auf.The gear attachment means may, for example, rotatably connect the gearbox with the wheelset shaft, so that the gearbox is designed to be axle-riding. Such a transmission is particularly simple and has a low weight.
Es kann auch als vorteilhaft angesehen werden, dass die Kupplung eine Lamellenkupplung oder Stahllamellenkupplung ist.It may also be considered advantageous that the clutch is a multi-plate clutch or steel disc clutch.
Die Stahllamellenkupplung ist wartungsfrei und weist eine kompakte Bauweise bei gleichzeitig geringem Gewicht auf. Dies schafft bei Anordnung der Antriebsvorrichtung im Drehgestell ausreichend Platz für einen für hohe Geschwindigkeiten ausgelegten Fahrmotor mit hoher Leistung.The steel disc clutch is maintenance-free and has a compact design with low weight. This creates sufficient space for a designed for high speeds traction motor with high performance in the arrangement of the drive device in the bogie.
Eine weitere vorteilhafte Ausgestaltung der Erfindung kann vorsehen, dass das Getriebe ein zum Umgreifen der Radsatzwelle vorgesehenes Großrad und ein mit diesem stirnseitig in Eingriff stehendes Ritzel aufweist, welches in Verbindung zur Kupplung steht und mittels dieser vom Fahrmotor antreibbar ist.A further advantageous embodiment of the invention can provide that the transmission has a large wheel provided for encompassing the wheel set shaft and a pinion which engages with the end face in this connection and which is connected to the clutch and can be driven by the traction motor.
Das Großrad kann beispielsweise drehfest mit der Radsatzwelle verbunden sein.The large wheel, for example, be rotatably connected to the wheelset.
Es kann auch als vorteilhaft angesehen werden, dass der Fahrmotor eine Motorwelle aufweist, wobei in einem montierten Zustand der Antriebsvorrichtung Ritzel, Kupplung und Motorwelle in einer Achse fluchtend angeordnet sind, wobei das Ritzel als Hohlwelle ausgebildet ist und die Kupplung zumindest teilweise umschließt.It can also be considered advantageous that the traction motor has a motor shaft, wherein in an assembled state of the drive device pinion, clutch and motor shaft are arranged in alignment in an axis, wherein the pinion is formed as a hollow shaft and the clutch at least partially surrounds.
