Description

Die Erfindung betrifft eine Bremsanordnung für Schienenfahrzeuge nach dem Oberbegriff des Anspruches 1.The invention relates to a brake arrangement for rail vehicles according to the preamble of claim 1.

Für Nahverkehrswagen mit relativ geringer Leistung und geringem Gewicht ist eine Konstruktion bekannt, bei welcher ein Ritzel des Antriebsmotors direkt ein Großrad auf der Radsatzwelle antreibt, wodurch ein den Verlust an Motorleistung erhöhendes Zwischenrad vermieden werden kann. Auf der dem Motor gegenüberliegenden Seite des Radsatzes ist ein eigener Abtrieb am Großrad vorgesehen, an dem fliegend eine Bremsscheibe montiert ist. Diese Anbringungsart einer Bremsscheibe ist jedoch für höhere Motorleistungen bzw. größere Fahrzeuggewichte aufgrund der höheren erforderlichen Bremsleistung und der damit verbundenen Belastung der Anbringung der Bremseinrichtungen nicht geeignet.For local passenger cars with relatively low power and low weight, a construction is known in which a pinion of the drive motor directly drives a large wheel on the axle shaft, whereby an intermediate wheel that increases the loss of engine power can be avoided. On the side of the wheel set opposite the engine, a separate output is provided on the large wheel, on which a brake disc is overhung. However, this type of attachment of a brake disc is not suitable for higher engine outputs or larger vehicle weights due to the higher required brake output and the associated load on the attachment of the brake devices.

Daher wurden bei Schienenfahrzeugen mit hoher Motorleistung und großem Gewicht die Bremsscheiben auf die Radachse bzw. die diese umgebende Hohlwelle angebaut, was jedoch den Nachteil aufweist, daß der Abstand zwischen dem Motor und der Radachse vergrößert werden muß, um für die Bremsscheiben Platz zu schaffen, sodaß nunmehr ein Zwischenrad im Getriebe erforderlich ist, welches zu einem zusätzlichen Leistungsverlust führt. Auch steht dabei nur ein relativ begrenzter Platz zur Anbringung der Bremsscheiben zur Verfügung.Therefore, in the case of rail vehicles with high engine output and great weight, the brake disks were mounted on the wheel axle or the hollow shaft surrounding it, but this has the disadvantage that the distance between the motor and the wheel axle must be increased in order to make space for the brake disks, so that now an idler gear is required in the transmission, which leads to an additional loss of performance. There is also only a relatively limited space available for attaching the brake discs.

Die Aufgabe der vorliegenden Erfindung bestand daher darin, eine auch für hohe Motorleistungen und hohe Fahrzeuggewichte geeignete Bremsanordnung mit ausreichender Bremsleistung anzugeben, bei der gleichzeitig der Verlust an Motorleistung möglichst gering gehalten werden kann und wobei das Platzangebot im Bereich der Radachse gut ausgenützt wird.The object of the present invention was therefore to provide a brake arrangement which is also suitable for high engine outputs and high vehicle weights and which has sufficient braking output and at the same time the loss of engine output can be kept as small as possible and the space available in the area of the wheel axle is well utilized.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teiles des Anspruches 1 gelöst.This object is achieved by the features of the characterizing part of claim 1.

Durch die zweiseitige Lagerung der Bremswelle ergibt sich eine mechanisch wesentlich stabilere Konstruktion, die wesentlich mehr Bremsleistung aufnehmen kann. Gleichzeitig bleibt aber die Möglichkeit erhalten, den Motor möglichst nahe der Radachse anzuordnen und damit ein den Leistungsverlust steigendes Zwischenrad im Getriebe zu vermeiden. Dies ist insbesondere bei Motoren mit über 1 MW Dauerleistung von Bedeutung, wo bereits Leistungsverluste oder -gewinne im Prozentbereich ausschlaggebend sind.The two-sided mounting of the brake shaft results in a mechanically much more stable construction that can absorb much more braking power. At the same time, however, there is still the possibility of arranging the motor as close as possible to the wheel axis and thus avoiding an intermediate wheel in the transmission which increases the power loss. This is particularly important for motors with a continuous output of more than 1 MW, where loss or gain in power is already decisive in the percentage range.

Die durch die erfindungsgemäße Konstruktion mögliche Anhebung der Bremsleistung führt auch zu einer Verringerung der thermischen und mechanischen Belastung der Räder, da der Einsatz der auf die Räder wirkenden Klotzbremsen vermieden werden kann.The increase in braking power possible through the construction according to the invention also leads to a reduction in the thermal and mechanical load on the wheels, since the use of the block brakes acting on the wheels can be avoided.

Durch die Merkmale der Ansprüche 2 und 3 kann leicht ein Wellenende freigelegt werden, um einen Bremsscheibenwechsel vorzunehmen oder allenfalls die ganze Welle in einfacher Weise ausbauen zu können.Due to the features of claims 2 and 3, a shaft end can easily be exposed in order to change the brake disc or, if need be, to remove the entire shaft in a simple manner.

Durch das Merkmal nach Anspruch 4 ist in Verbindung mit dem zuvor genannten Merkmal des lösbaren Lagers auch ein modularer Aufbau mit entsprechend dem geplanten Einsatzzweck veränderlicher Anzahl der Bremsscheiben auf der Bremswelle denkbar. Das erfindungsgemäß ausgerüstete Schienenfahrzeug kann für jeden Zweck mit der passenden Bremsleistung versehen werden, wobei dies lediglich vom Platzangebot auf der Bremswelle nach oben hin begrenzt ist. Eine vorteilhafte Maßnahme ergibt sich durch das Merkmal nach Anspruch 5.The feature according to claim 4, in conjunction with the aforementioned feature of the detachable bearing, also allows a modular structure with a variable number of brake disks on the brake shaft in accordance with the intended use. The rail vehicle equipped according to the invention can be provided with the appropriate braking power for any purpose, this being limited only by the space available on the brake shaft. An advantageous measure results from the feature according to claim 5.

Dazu könnte einerseits die gesamte Bremswelle ausgetauscht und durch eine andere Bremswelle mit einer anderen Anzahl von darauf fest montierten Bremsscheiben ersetzt werden.For this purpose, the entire brake shaft could be replaced on the one hand and replaced by another brake shaft with a different number of brake discs fixedly mounted thereon.

Durch das Merkmal des Anspruches 6 ist es möglich, daß in weniger aufwendiger Weise zum Auf- oder Abbau der Bremsleistung lediglich die gewünschte Anzahl an Bremsscheiben zusätzlich angebracht oder abgebaut wird.Due to the feature of claim 6, it is possible that only the desired number of brake disks is additionally attached or removed in a less complex manner for setting up or removing the braking power.

Durch das Merkmal nach Anspruch 7 sind Relativbewegungen zwischen den Bremsscheiben und den Bremssätteln vermieden, sodaß eine gleichmäßige Aufbringung der Bremsleistung und ein konstruktiv einfacher Aufbau unter Vermeidung schwimmend gelagerter Bauteile gewährleistet ist.By the feature of claim 7, relative movements between the brake discs and the brake calipers are avoided, so that a uniform application of the braking power and a structurally simple structure is avoided while avoiding floating components.

An advantageous embodiment will be explained in more detail in the following description with reference to the drawings. Show
Fig. 1
a side view of a motor-transmission unit with a brake arrangement according to the invention and
Fig. 2
2 shows a top view of the component group of FIG. 1.

Der Antriebsmotor ist mit 1 bezeichnet und liefert typischerweise bei modernen Hochleistungslokomotiven eine Dauerleistung von etwa 1,6 MW. Ein daran angeflanschtes Getriebe 2 treibt einerseits eine Hohlwelle 3 an, welche antriebsmäßig mit einer konzentrischen Radsatzachse (nicht dargestellt) verbunden ist. Gleichzeitig ist aber auch an der dem Motor 1 entgegengesetzten Seite der Hohlwelle 3 ein Abtrieb vorgesehen, mit dem eine Bremswelle 4 einer Scheibenbremse ohne eines Zwischenrades antriebsmäßig verbunden ist, welche parallel zur Radachse bzw. Hohlwelle 3 angeordnet ist.The drive motor is designated 1 and typically delivers a continuous output of about 1.6 MW in modern high-performance locomotives. A flanged gear 2 drives on the one hand a hollow shaft 3, which is connected in terms of drive to a concentric axle set (not shown). At the same time, however, an output is also provided on the side of the hollow shaft 3 opposite the motor 1, to which a brake shaft 4 of a disc brake without an intermediate wheel is connected in terms of drive, which is arranged parallel to the wheel axis or hollow shaft 3.

Die Bremswelle 4 ist nun einerseits bei 5 im Gehäuse des Getriebes 2 und anderseits am gegenüberliegenden Ende im vorderen Bereich 6 eines vom Motor 1 ausgehenden Trägers drehbar gelagert.The brake shaft 4 is now on the one hand at 5 in the housing of the Gearbox 2 and on the other hand rotatably mounted at the opposite end in the front region 6 of a carrier extending from the engine 1.

Wie bei 7 durch eine Flanschverbindung angedeutet ist, ist der vordere Teil 6 des Trägers und damit das der antriebsmäßigen Verbindung der Bremswelle mit der Hohlwelle 3 gegenüberliegende Lager lösbar und entfernbar. Damit sind die auf der Bremswelle 4 vorgesehenen Bremsscheiben 8 im Falle ihrer lösbaren Anbringung leicht abnehmbar bzw. wieder auf der Bremswelle 4 montierbar oder es ist allenfalls die gesamte Bremswelle 4 mit den darauf befindlichen Bremsscheiben 8 abnehmbar.As indicated at 7 by a flange connection, the front part 6 of the carrier and thus the bearing opposite the drive connection of the brake shaft to the hollow shaft 3 can be detached and removed. In this way, the brake disks 8 provided on the brake shaft 4 can be easily removed in the event of their detachable attachment or can be mounted again on the brake shaft 4, or at most the entire brake shaft 4 with the brake disks 8 located thereon can be removed.

Die auf die Bremsscheiben 8 wirkenden Bremssättel 9 sind zur Vermeidung von Relativbewegungen vorteilhafterweise ebenso an der Motor-Getriebe-Einheit 1, 2 angebracht, können aber auch am Drehgestellrahmen (nicht dargestellt) montiert sein.The brake calipers 9 acting on the brake disks 8 are advantageously also attached to the motor-gear unit 1, 2 in order to avoid relative movements, but can also be mounted on the bogie frame (not shown).

Obwohl in der Zeichnung beispielhaft zwei Bremsscheiben 8 dargestellt sind, ist deren Höchstanzahl nur durch die Länge der Bremswelle 4 nach oben hin begrenzt, während selbst bei lediglich einer Bremsscheibe durch die mechanisch wesentlich stabilere zweiseitige Lagerung der Bremswelle 4 die Bremsleistung gegenüber herkömmlichen Konstruktionen mit einer Bremsscheibe deutlich erhöht ist.Although two brake disks 8 are shown by way of example in the drawing, the maximum number of them is only limited by the length of the brake shaft 4, while even with only one brake disk, the mechanically much more stable two-sided mounting of the brake shaft 4 reduces the braking power compared to conventional designs with a brake disk is significantly increased.

Ein zusätzlicher Vorteil ergibt sich bei der Verwendung der dargestellten Baugruppe in einem zweiachsigen Triebdrehgestell, da aufgrund des geringen Abstandes zwischen Motor 1 und der Hohlwelle 3, innerhalb derer die Radsatzachse verläuft, ein Drehgestell mit deutlich kürzerem Achsstand erzielbar ist, welches durch diesen engen Radstand eine deutlich verbesserte Kurvengängigkeit aufweist. Ein Triebdrehgestell unter Verwendung der erfindungsgemäßen Bremsenanordnung vereint in sich die Vorteile eines verminderten Leistungsverlustes, erhöhter Bremsleistung und kurzem Abstand der Radsätze mit damit verbesserter Kurvengängigkeit.An additional advantage arises when the assembly shown is used in a two-axle drive bogie, because due to the small distance between the motor 1 and the hollow shaft 3 within which the axle of the wheelset runs, a bogie with a significantly shorter wheelbase can be achieved, which has a significantly improved cornering ability due to this narrow wheelbase. A powered bogie using the brake arrangement according to the invention combines the advantages of reduced power loss, increased braking power and a short distance between the wheel sets with improved cornering.

Die Vergrößerung des Platzbedarfes auf der dem Motor 1 gegenüberliegenden Seite der Hohlwelle 3 ist nicht von Bedeutung, da dieser Platz in herkömmlichen Drehgestellen größtenteils ungenutzt ist.The increase in the space requirement on the side of the hollow shaft 3 opposite the motor 1 is not important since this space is largely unused in conventional bogies.

Die zur Aufnahme der Lager der Bremswelle 4 vorgesehenen Abschnitte des Gehäuses für das Getriebe 2 bzw. des vorderen Teiles 6 des Trägers auf der dem Gehäuse des Getriebes 2 gegenüberliegenden Seite können vorteilhafterweise gleich mit Anbringungsstellen 10 für Bauteile zur Aufhängung der Motor-Getriebe-Einheit 1,2 zusammen mit der Bremsenanordnung am Drehgestellrahmen oder auch am Fahrzeugrahmen genutzt werden.The sections of the housing for the transmission 2 or the front part 6 of the carrier provided for receiving the bearings of the brake shaft 4 on the side opposite the housing of the transmission 2 can advantageously be provided with attachment points 10 for components for suspending the motor-transmission unit 1 , 2 can be used together with the brake arrangement on the bogie frame or on the vehicle frame.
