Abstract

A bogie for a rail vehicle comprises a hollow jacket having opposite open end faces forming an electric motor housing. A stator winding assembly is press fit into the hollow jacket and receives a rotatably mounted motor shaft which has an axis extending parallel to the direction of travel of the rail vehicle. A cross-beam having side parts is connected directly, for example, by welding to the hollow jacket. A motor bearing bracket is connected and closes the opposite end faces of the hollow jacket and carries a bearing through which the motor shaft is mounted. The motor shaft is connected to a miter gear, a differential gear, Cardan shafts and couplings, to bogie wheels. Double linkages may be connected to axles of the wheels with wheels on opposite sides of the bogie and at either end of the bogie having linkages which are connected to each other.

Description

Die Erfindung betrifft ein Drehgestell für Schienenfahrzeuge, z.B. Straßenbahnen, mit einem in Fahrtrichtung liegenden Antriebsmotor, an dessen Stirnseiten je ein Winkelgetriebe angeordnet ist, das über ein Differentialgetriebe mittels Kardanwellen und Kupplung mit den in Pendelrahmen oder Schwingen gelagerten Laufrädern einer Gestellachse verbunden ist.The invention relates to a bogie for rail vehicles, e.g. Trams, with a drive motor lying in the direction of travel, on the end faces of which an angular gear is arranged, which is connected via a differential gear by means of cardan shafts and a clutch to the wheels of a frame axle mounted in a pendulum frame or swing arm.

Es ist bekannt, die Achsen eines Drehgestells für Schienenfahrzeuge, wie Straßenbahnen, mit einem in Fahrtrichtung liegenden Antriebsmotor über je ein an dessen Stirnseiten angeordnetes Winkelgetriebe und über je eine die Achse mit Spiel umgebende Hohlwelle und entsprechende Anschlußkupplungen anzutreiben.It is known to drive the axles of a bogie for rail vehicles, such as trams, with a drive motor lying in the direction of travel, each via an angular gear arranged on its end faces and via a hollow shaft surrounding the axle with play, and corresponding connection couplings.

Bei dieser Bauweise der Drehgestelle gleichen die über die Achse starr miteinander verbundenen Laufräder die verschiedenen Weglängen bei Kurvenfahrten größtenteils selbst durch die kegelartige Neigung ihres Radkranzes aus. Dieser Längenausgleich ist mit einer mehr oder weniger großen Gleitreibung, mit Spurkranz- bzw. Bandagenverschleiß und unter Umständen unliebsamen Quietschgeräuschen verbunden.In this type of construction of the bogies, the wheels rigidly connected to one another via the axle largely compensate for the different path lengths when cornering even through the conical inclination of their wheel rim. This length compensation is with a more or less high sliding friction, associated with wheel flange or bandage wear and possibly unpleasant squeaking noises.

Um diese Nachteile zu beseitigen, hat man bisher die Laufräder statt auf sie starr verbindenden Achsen auf Halbachsen angeordnet, die jeweils in Halbdrehgestellen, Pendelrahmen oder Schwingen gelagert sind, wo sie entweder einzeln oder seitenweise angetrieben werden.In order to eliminate these disadvantages, the wheels have been arranged on semi-axles instead of axially rigidly connecting them, which are each mounted in half bogies, pendulum frames or swing arms, where they are driven either individually or side by side.

Ein bisher unveröffentlichter Vorschlag geht bereits dahin, daß die Räder von einem einzigen in Fahrzeugmitte und in Fahrtrichtung gelegenen Motor mit zwei Abtriebswellenstümpfen über Winkelgetriebe, Differentiale, Kupplungen und Kardanwellen angetrieben werden.A previously unpublished proposal is that the wheels are driven by a single motor located in the center of the vehicle and in the direction of travel with two output shaft ends via angular gears, differentials, clutches and cardan shafts.

Derartige Drehgestelle sind verhältnismäßig schwer und tragen den Bestrebungen nach einem Leichtbau von schnellen Fahrzeugen noch keineswegs Rechnung.Such bogies are relatively heavy and do not yet take into account the efforts to lightweight lightweight vehicles.

Die Erfindung hat sich zur Aufgabe gestellt, diese Nachteile zu beseitigen und ein Drehgestell mit Mittelantrieb zu schaffen, das wesentlich leichter ist als die bisher üblichen. Sie besteht darin, daß der Antriebsmotor in bekannter Weise in dem die Seitenteile des Drehgestells verbindenden, mit einem Hohlmantel versehenen Querträger gehalten ist, wobei der Hohlmantel zugleich als elektrisch wirksames Motorgehäuse ausgebildet ist, in das die Statorwicklungen eingeschoben sind und das stirnseitig von Motorlagerschilden verschlossen ist.The invention has set itself the task of eliminating these disadvantages and creating a bogie with a central drive, which is much lighter than the previously common. It consists in that the drive motor is held in a known manner in the cross member connecting the side parts of the bogie and provided with a hollow jacket, the hollow jacket being designed at the same time as an electrically effective motor housing into which the stator windings are inserted and which is closed at the end by motor end shields .

Es ist zwar bekannt, beispielsweise durch die DE-PS 566 698, bei Drehgestellen mit durchgehenden starren Achsen die Querverbindung der Drehgestelllangträger mit einem Gehäuse zur Aufnahme des Antriebsmotors zu versehen, wobei dieses der Halterung dienende Gehäuse nicht die Funktion des elektrisch wirksamen Motormantels ausübt. Durch das Einschieben des eigentlichen Motorgehäuses in diese Halterung fällt diese Bauweise noch sehr schwer aus.It is known, for example from DE-PS 566 698, in bogies with continuous rigid axles the cross connection of the bogie long carrier to be provided with a housing for receiving the drive motor, said housing serving as the holder not performing the function of the electrically active motor jacket. By pushing the actual motor housing into this bracket, this construction is still very difficult.

Vorteilhaft ist der Hohlmantel unter Wegfall besonderer Motorlagerschilde unmittelbar von den Flanschen der Winkelgetriebe verschlossen und die Motorwelle in an sich bekannter Weise mit in den Ritzellagern der Winkelgetriebe gelagert. Die Mitbenutzung der Ritzellager der Winkelgetriebe zur Lagerung der Motorwelle ist zwar bereits durch die DE-OS 25 48 058 bekannt, wo sie insbesondere zur Verkürzung der Motorlänge dient. Im vorliegenden Falle dient sie im Zusammenhang mit dem Hauptanspruch insbesondere zur weiteren Gewichtserleichterung.Advantageously, the hollow jacket is closed directly by the flanges of the angular gears and special motor end shields are omitted, and the motor shaft is supported in a manner known per se in the pinion bearings of the angular gears. The use of the pinion bearing of the angular gear for mounting the motor shaft is already known from DE-OS 25 48 058, where it is used in particular to shorten the motor length. In the present case, it serves in connection with the main claim in particular to further reduce weight.

Eine weitere, ebenfalls der Gewichtsverminderung des Drehgestells dienende Maßnahme besteht darin, daß doppelwandige Schwingen jeweils eines der Laufräder gelagert einschließen und zusammen mit Elementen, die die sich gegenüberliegenden Schwingenenden einer Gestellachse miteinander verbinden, einen Rahmen bilden und an den der Gestellmitte zugewandten Enden gelenkig, z.B. über Silentblöcke, mit den Seitenteilen des Drehgestells verbunden sind sowie sich etwa in ihrer Mitte unter Zwischenschaltung eines Federkörpers an einem Ausleger der Seitenteile abstützen.A further measure, which also serves to reduce the weight of the bogie, is that double-walled rockers each enclose one of the running wheels and form a frame together with elements which connect the opposite rocker ends of a frame axis and are articulated at the ends facing the center of the frame, e.g. are connected to the side parts of the bogie via silent blocks and are supported approximately in the middle with the interposition of a spring body on an extension arm of the side parts.

Es hat sich dabei als besonders vorteilhaft erwiesen, die Verbindung einer der Schwingen einer Gestellachse mit demDrehgestellseitenteil durch ein Doppelgelenk zu bewerkstelligen, dem das Doppelgelenk der weiteren Gestellachse diagonal gegenüberliegt. Die Anwendung dieser Doppelgelenke erleichtert eine Schränkung der Achsen, wie sie z.B. beim Auflaufen eines Spürkranzes vorkommt.It has proven to be particularly advantageous to connect one of the swing arms of a frame axis to the bogie side part by means of a double joint to accomplish which the double joint of the further frame axis is diagonally opposite. The use of these double joints makes it easier to set the axles, as occurs, for example, when a track ring comes up.

Zweckmäßig sind die Verbindungselemente, welche die Schwingen einer Gestellachse rahmenartig verbinden, als dünnwandige Rohre ausgeführt und gegebenenfalls aus Leichtmetall hergestellt. Auch die Schwingen können vorteilhaft aus demselben Material bestehen. Somit kann diese Konstruktion sehr leicht ausgeführt werden.The connecting elements, which connect the rockers of a frame axis in a frame-like manner, are expediently designed as thin-walled tubes and, if appropriate, made of light metal. The rockers can also advantageously consist of the same material. This construction can therefore be carried out very easily.

Die zwischen den Wänden einer jeden Schwinge einzeln gelagerten Laufräder werden durch die rahmenartige Verbindung der Schwingen einer Gestellachse absolut parallel zueinander geführt. Die Laufräder brauchen in den Schwingen auch nicht gefedert zu lagern: vielmehr erfolgt eine Federung der Schwingen und der Räder gemeinsam.The wheels mounted individually between the walls of each rocker are guided absolutely parallel to each other by the frame-like connection of the rockers of a frame axis. The wheels do not need to be spring-loaded in the swingarms; rather, the swingarms and the wheels are sprung together.

Mit 1 ist ein Querträger bezeichnet, der die Seitenteile 18 des Drehgestells verbindet, indem er in dem betroffenen Bereich selbst als Drehgestellseitenteil ausgebildet ist, und in der Längsmitte des Drehgestells einen Hohlmantel 2 eingeschweißt trägt, der als elektrisch wirksames Motorgehäuse für den Gestellantrieb dient und in den die Statorwicklungen 3 eingeschoben sind. Der Hohlmantel 2 kann, wie in Fig. 3 gestrichelt gezeichnet, gegebenenfalls auch längsgeteilt ausgeführt sein, wodurch die Montage der Statorwicklungen 3 erleichtert wird.1 with a cross member is designated, which connects the side parts 18 of the bogie, in that it is designed as a bogie side part in the area concerned, and carries a hollow jacket 2 welded in the longitudinal center of the bogie, which serves as an electrically effective motor housing for the frame drive and in which the stator windings 3 are inserted. The hollow jacket 2 can, as shown in dashed lines in Fig. 3, optionally also be made longitudinally, whereby the assembly of the stator windings 3 is facilitated.

Der Hohlmantel 2 ist auf der linken Seite der Fig. 2 stirnseitig von einem Lagerschild 4 (stellvertretend für beide Mantelenden) verschlossen, gegen den ein am Hohlmantel 2 befestigtes Winkelgetriebe 5 anliegt und in dem der Motorläufer 6 gelagert ist. Bei der Ausführung auf der rechten Seite der Fig. 2 ist der Hohlmantel 2 unmittelbar von dem Flansch 7 des Winkelgetriebes 5a (stellvertretend für beide Mantelenden) verschlossen, wobei die Welle 6a des Motorsläufers 6mit in Lagern 8 des Ritzels des Winkelgetriebes 5a gelagert ist. Die Winkelgetriebe 5 oder 5a treiben über Kardanwellen 9 und 9a und Gelenkkupplungen 10, 11 und lla die Laufräder 12 an. Diese sind im oberen Teil der Fig. 2 zur Erzielung eines möglichst großen Gelenkabstandes der Kardanwelle 9a im Falle von Schränkungen auf Hohlwellen 13 gelagert, wobei die Kardanwelle 9a die Hohlwelle 13 durchdringt und mit dieser durch die Gelenkkupplung lla verbunden ist, die auf der Drehgestellaußenseite liegt.The hollow jacket 2 is closed on the left side of FIG. 2 by a bearing plate 4 (representative of both jacket ends), against which an angular gear 5 fastened to the hollow jacket 2 rests and in which the motor rotor 6 is mounted. In the embodiment on the right-hand side of FIG. 2, the hollow casing 2 is closed directly by the flange 7 of the angular gear 5a (representative of both casing ends), the shaft 6a of the motor rotor 6 being supported in bearings 8 of the pinion of the angular gear 5a. The angular gear 5 or 5a drive the impellers 12 via cardan shafts 9 and 9a and articulated couplings 10, 11 and 11a. These are mounted in the upper part of Fig. 2 to achieve the greatest possible joint distance of the propeller shaft 9a in the case of restrictions on hollow shafts 13, the propeller shaft 9a penetrating the hollow shaft 13 and being connected to it by the articulated coupling lla, which is located on the outside of the bogie .

Die Laufräder 12 sind in Schwingen 14 gelagert, die jeweils zwei in Fahrtrichtung parallel zueinander verlaufende Stege besitzen und mit diesen jeweils ein Laufrad 12 einschließen. Die Stege sind an den Enden 15 und 15a fest miteinander verbunden. Zwei Schwingen 14 jeweils einer Gestellachse sind außerdem an den sich gegenüberliegenden Enden 15 bzw. 15a durch dünnwandige Rohre 16 miteinander verbunden, so daß dadurch zusammen mit den Schwingen ein jochartiges Gebilde entsteht.The wheels 12 are mounted in rockers 14, each of which has two webs running parallel to each other in the direction of travel and with each of them include an impeller 12. The webs are firmly connected to one another at the ends 15 and 15a. Two rockers 14 each having a frame axis are also connected to one another at the opposite ends 15 and 15a by thin-walled tubes 16, so that a yoke-like structure is formed together with the rockers.

An ihren Enden 15a sind die Schwingen 14 gelenkig mit den Seitenteilen 18 des Drehgestells verbunden. Dabei ist ein Gelenk jeder Gestellachse als Einfachgelenk 17 und das weitere Gelenk als Doppelgelenk 17a ausgebildet, wobei sich die Doppelgelenke 17a jeder Gestellachse diagonal gegenüberliegen. Diese Anwendung der Doppelgelenke 17a erleichtert eine Schränkung der Achsen, wie sie z.B. beim Auflaufen eines Spurkranzes vorkommt (vergl. Fig. 4). In ihrer Mitte sind die Schwingen 14 unter Zwischenschaltung einer Feder 19 an einem Ausleger 20 der Seitenteile 18 abgestützt. Auf diese Weise sind die Schwingen 14 einschließlich der Laufräder 12 gegenüber dem übrigen Drehgestell gefedert abgestützt, so daß auf eine aufwendige Einzelabfederung der Räder verzichtet werden kann.At their ends 15a, the rockers 14 are articulated to the side parts 18 of the bogie. One joint of each frame axis is designed as a single joint 17 and the further joint as a double joint 17a, the double joints 17a of each frame axis being diagonally opposite. This application of the double joints 17a makes it easier to set the axes, e.g. occurs when a flange meets (see Fig. 4). In the middle, the rockers 14 are supported on a cantilever 20 of the side parts 18 with the interposition of a spring 19. In this way, the rockers 14 including the wheels 12 are spring-loaded with respect to the rest of the bogie, so that there is no need for complex individual suspension of the wheels.

Auf den Seitenteilen 18 des Drehgestells ist der Wagenkasten in üblicher Weise unter Zwischenschaltung von Federn 21 (Sekundärfederung) abgestützt, die auch Luft- oder Hydraulikfedern sein können.On the side parts 18 of the bogie, the body is supported in the usual way with the interposition of springs 21 (secondary suspension), which can also be air or hydraulic springs.
