The shaft is connected to the drive by a coupling allowing movements for uneven pieces of rail. The hollow shaft (1) has a brake disc (2); and the motor and drive assembly (3) has a brake appliance attached to it, made up from brake calipers (4) and drive (5), such as compressed-air cylinder. The suspension is fully effective during braking.

Description

Triebdrehgestell für ein Schienenfahrzeug Motor bogie for a rail vehicle

Die Erfindung betrifft ein Triebdrehgestell für ein Schienenfahrzeug, das mit einer Scheibenbremsanlage ausgerüstet ist und bei dem eine in einem Motor/Getriebeaggregat gelagerte und davon betriebene Hohlwelle eine Radsatzwelle konzentrisch, mit Spiel umschließt, wobei die Radsatzwelle durch ein räumliche Bewegungen dieser Welle infolge von Schienenunebenheiten oder dergleichen zulassendes Kupplungsmittel (beispielsweise eine Gummikupplung oder eine gelenkige Stangenanordnung) kraftschlüssig mit der Hohlwelle verbunden ist.The invention relates to a motor bogie for a rail vehicle, which is equipped with a disc brake system and one in a motor / gear unit mounted and driven by it hollow shaft a wheelset shaft concentric, with play encloses, the wheelset shaft as a result of a spatial movement of this shaft coupling means (e.g. a rubber coupling or an articulated rod arrangement) frictionally with the Hollow shaft is connected.

Triebdrehgestelle mit den vorgenannten Merkmalen sind insbesondere bei Schienenfahrzeugen des Personennahverkehrs in Anwendung. Ihre Bremsanlage besteht im wesentlichen aus einer Bremsscheibe und einem aus Bremszange sowie Antrieb gebildeten Bremsgerät, wobei die Bremsscheibe entweder auf der Radsatzwelle oder unmittelbar am Radkörper und das Bremsgerät am Drehgestelirahmen befestigt sind. Durch die vorgenannte Bremsanordnung liegt während des Bremsvorganges eine starre Verbindung zwischen dem Radsatz und dem Drehgestellrahmen vor, so daß die Radsatzfederung des Triebdrehgestelles in nachteiliger Weise ausgeschaltet ist. Aus dem Erfordernis, die Bremsbeläge auch bei maximaler Einfederung des Rahmens vollflächig an der Scheibe zur Anlage zu bringen - um einen anderenfalls auf tretenden einseitigen Verschleiß, insbesondere Einschliffe, der Beläge zu vermeiden -, ergeben sich weiter nachteilig entsprechend verkleinerte Bremsbeläge. Schließlich kann bei räumlichen Bewegungen des Radsatzes, die zum Ausgleich von beispielsweise durch Schienenunebenheiten hervorgerufenen Stößen an sich gewünscht sind, ein Schleifen der Bremsbeläge an der Scheibe auftreten, was zu einer erheblich verringerten Standzeit dieser Teile und zu einer unerwünschten Geräuschentwicklung führt.Motor bogies with the aforementioned features are in particular in use in rail vehicles for local passenger transport. Your braking system exists essentially formed from a brake disc and a brake caliper and drive Braking device, with the brake disc either on the axle or directly are attached to the wheel center and the braking device to the bogie frame. By the aforementioned Brake arrangement is a rigid connection between during the braking process the wheelset and the bogie frame, so that the wheelset suspension of the motor bogie is switched off in a disadvantageous manner. From the requirement, the brake pads too to be brought into contact with the pane over the entire surface when the frame is deflected to the maximum - to prevent unilateral wear that would otherwise occur, in particular cuts, To avoid the coverings -, there are further disadvantageously correspondingly reduced Brake pads. Finally, in the case of spatial movements of the wheelset, the compensation for example bumps caused by uneven tracks are desired, the brake pads rub against the disc, resulting in a significantly reduced service life of these parts and an undesirable one Noise development leads.

Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Triebdrehgestell der gattungsgemäßen Art unter Beseitigung der vorgenannten Nachteile hinsichtlich der Anordnung seiner Scheibenbremsanlage zu verbessern; dabei sollen insbesondere seine brems- und federtechnischen Eigenschaften gesteigert werden.The invention is accordingly based on the object of a motor bogie of the generic type while eliminating the aforementioned disadvantages with regard to to improve the arrangement of its disc brake system; in particular its braking and spring properties can be increased.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Hohlwelle eine Bremsscheibe trägt und am Motor/Getriebeaggregat ein aus einer Bremszange und einem Antrieb (z.B. einem Druckluftzylinder) gebildetes Bremsgerät angeschlossen ist.According to the invention, this object is achieved in that the hollow shaft carries a brake disc and a brake caliper and on the motor / gear unit connected to a drive (e.g. a compressed air cylinder) is.

Das erfindungsgemäße Triebdrehgestell zeichnet sich vorteilhaft dadurch aus, daß seine Radsatzfederung auch während des Bremsvorganges voll wirksam ist. Daraus resultiert im besonderen eine Steigerung des Fahrkomforts, der außerdem dadurch günstig beeinflußt wird, weil die unabgefederte Masse des Triebdrehgestelles um das oftmals erhebliche Gewicht der Bremsscheibe reduziert ist, und die Bremskraft durch das Kupplungsmittel zwischen Hohlwelle und Radsatzwelle gedämpft eingesetzt. Da Bremsscheibe und Bremsgerät an zueinander starr gelagerten Teilen befestigt sind - zwischen Scheibe und Gerät also keine Federung vorliegt - ist weiter vorteilhaft einerseits in einfacher Weise eine genaue Montage möglich, andererseits können die Bremsbeläge in ihren Abmessungen im Hinblick auf den zur Verfügung stehenden Bremsscheibendurchmesser vergrößert werden; insgesamt gesehen ergeben sich daraus ein höherer Wirkungsgrad sowie eine längere, wartungsfreie Einsatzdauer der Bremsanlage.The motor bogie according to the invention is advantageously characterized from that its suspension is fully effective even during braking. This results in an increase in driving comfort in particular, which also results from it is favorably influenced because the unsprung mass of the motor bogie to the often considerable weight of the brake disc is reduced, and the braking force Used dampened by the coupling means between the hollow shaft and the wheelset shaft. Because the brake disc and brake device are attached to parts that are rigidly mounted to one another - there is no suspension between the disc and the device - is further advantageous on the one hand, in a simple manner, an accurate assembly possible, on the other hand, the Brake pads in their dimensions with regard to the available brake disc diameter be enlarged; Overall, this results in a higher degree of efficiency as well as a longer, maintenance-free service life of the brake system.

Es zeigen Fig. 1 eine Hälfte eines Triebdrehgestelles, im Grundriß, schematisch dargestellt, Fig. 2 die Ansicht in Richtung des Pfeiles Z in Fig. 1, im Uhrzeigersinn um 900 gedreht, vergrößert dargestellt.The invention is based on an embodiment shown in the drawing explained in more detail. 1 shows one half of a motor bogie, in plan, shown schematically, Fig. 2 the view in the direction of the arrow Z in Fig. 1, rotated clockwise by 900, shown enlarged.

Das zweiachsige Triebdrehgestell nach den Fig. i und 2 enthält ein Motor/Getriebeaggregat 3, in dem eine Hohlwelle 1 drehbar gelagert ist. Die Hohlwelle i umschließt die Radsatzwelle 6 mit Spiel und ist mit dieser Welle 6 durch Gunmikupplungen 7 verbunden, die im Hinblick auf Betriebskräfte, Elastizitätsforderungen und das Aggregatgewicht ausgelegt sind; dieses Gewicht kann auch durch den nicht dargestellten Drehgestellrahmen aufgenommen werden.The two-axle motor bogie according to FIGS. I and 2 contains a Motor / gear unit 3 in which a hollow shaft 1 is rotatably mounted. The hollow shaft i surrounds the wheelset shaft 6 with play and is connected to this shaft 6 by gunmicro couplings 7 connected with regard to operating forces, elasticity requirements and the Unit weight are designed; this weight can also be achieved by the not shown Bogie frame are included.

Die Bremsanlage des Drehgestelles besteht im wesentlichen aus einer auf der Hohlwelle 1 befestigten Bremsscheibe 2 sowie einem aus Bremszange 4 und Antrieb 5 gebildeten Bremsgerät.The braking system of the bogie essentially consists of one on the hollow shaft 1 attached brake disc 2 and one of brake caliper 4 and Drive 5 formed braking device.

Wie aus Fig. 1 und 2 ersichtlich, sind die Bremszange 4 und die daran angelenkten Bremsbelagträger 4a in Festpunkten 3a am Gehäuse des Motor/Getriebeaggregates 3 aufgehängt; der Antrieb 5 ist an dem freien Ende der Bremszange 4 gelagerteAs can be seen from FIGS. 1 and 2, the brake caliper 4 and the one on it hinged brake lining 4a in fixed points 3a on the housing of the motor / gear unit 3 suspended; the drive 5 is mounted on the free end of the brake calliper 4
