Definitions
- the invention relates to a motor bogie for electric locomotives according to the preamble of claim 1.
- Hiebei is primarily intended for a motor bogie that allows a maximum speed of 250 km / h.
- a powered bogie generally consists of a chassis frame, in which two drive wheel sets are connected to the axle bearing housing and spring and damper elements in a suitable manner. Furthermore, a drive motor with a drive is provided for each drive wheel set, which can be stiffly suspended in the chassis frame.
- the traction motors are used as so-called absorbers, which absorb vibrations of the bogie transversely to the direction of travel as well as torsional vibrations about the vertical axis of the bogie.
- the BE-A-466 999 shows an engine mount that consists of pendulums and coil springs. In this engine mount, eradication of the fluctuations in the transverse direction is neither intended nor intended.
- the object of the present invention is to create measures by means of which the abovementioned repayment is optimized and a suspension of the motor is ensured transversely to the direction of travel.
- 1 denotes the bogie frame, in which two wheel sets 2 and 3 are mounted in the usual way, and are each driven by a traction motor 21.
- the present invention uses not only the installation of anti-roll dampers between the locomotive body and the bogie, but also the effect generally known in the art as redemption.
- This so-called elastic engine suspension can compensate for transverse and torsional vibrations occurring about the vertical axis 20 of the motor bogie, whereby the stability of the vehicle undergoes a decisive improvement.
- Each of the two motors 21 is suspended from the frame 1 at three points.
- the point on the head support 22 of the bogie frame is called the joint 23 trained, the rotations of the motor around its vertical axis, ie allows an axis transverse to the direction of travel.
- the two other suspension points 6, 7 are located on the cross member 24 of the bogie frame 1.
- two leaf springs 25, 25 'designed as double-sided cantilevers lead perpendicular to the clamping points 8, 9 on the motor 21 (FIG. 4).
- FIG. 5 shows the clamping of the springs 25, 25 'in the cross member 24 of the bogie frame 1.
- the springs 25, 25' have a corrugation 32 at their upper end, which is opposed to a corrugation in a crossbeam 33 of the cross member 24.
- the springs with the corrugation are pressed against the corrugation of the crossbeam 33 by means of wedges 34, so that a kind of tensioning unit is created.
- the two wedges 34 are connected by at least one crossbar 35 (FIG. 2), which are clamped to the crossbar 33 by a screw connection 36.
- a hydraulic steamer 26 is installed between the engine 21 and the frame in the direction transverse to the longitudinal axis of the vehicle (FIG. 1). The repayment is thus based on the transverse spring rate with the hydraulic transverse damper 26 connected to it.

Abstract
Description
Die Erfindung betrifft ein Triebdrehgestell für elektrische Lokomotiven nach dem Oberbegriff des Patentanspruches 1. Hiebei ist vor allem an ein Triebdrehgestell gedacht, das eine maximale Geschwindigkeit von 250 km/h erlaubt.The invention relates to a motor bogie for electric locomotives according to the preamble of claim 1. Hiebei is primarily intended for a motor bogie that allows a maximum speed of 250 km / h.
Ein Triebdrehgestell besteht im allgemeinen aus einem Fahrwerksrahmen, in dem zwei Triebradsätze über Achslagergehäuse und Feder- sowie Dämpferelemente mit diesem in geeigneter Weise verbunden sind. Weiters ist bei jedem Triebradsatz ein Fahrmotor mit Antrieb vorgesehen, der in dem Fahrwerksrahmen steif aufgehängt sein kann.A powered bogie generally consists of a chassis frame, in which two drive wheel sets are connected to the axle bearing housing and spring and damper elements in a suitable manner. Furthermore, a drive motor with a drive is provided for each drive wheel set, which can be stiffly suspended in the chassis frame.
Um die Stabilität des Fahrzeuglaufes zu erhöhen, verwendet man die Fahrmotoren als sogenannte Tilger, die sowohl Schwingungen des Drehgestelles quer zur Fahrtrichtung, als auch Drehschwingungen um die Hochachse des Drehgestelles tilgen.In order to increase the stability of the vehicle running, the traction motors are used as so-called absorbers, which absorb vibrations of the bogie transversely to the direction of travel as well as torsional vibrations about the vertical axis of the bogie.
Durch die DE-PS 2 837 302 ist eine schwenkbare Fahrmotor- und Getriebelagerung in einem Triebdrehgestell bekannt geworden. Hiebei erfolgt die Aufhängung des Motors über Pendel im Drehgestellrahmen.From DE-PS 2 837 302 a pivotable drive motor and gearbox mounting in a motor bogie has become known. The engine is suspended via a pendulum in the bogie frame.
Die BE-A-466 999 zeigt eine Motoraufhängung, die aus Pendeln und Schraubenfedern besteht. Bei dieser Motoraufhängung ist eine Tilgung der Schwankungen in Querrichtung weder vorgesehen noch beabsichtigt.The BE-A-466 999 shows an engine mount that consists of pendulums and coil springs. In this engine mount, eradication of the fluctuations in the transverse direction is neither intended nor intended.
Aufgabe der vorliegenden Erfindung ist die Schaffung von Maßnahmen, durch welche die oben erwähnte Tilgung optimiert, eine Federung des Motors quer zur Fahrtrichtung gewährleistet wird.The object of the present invention is to create measures by means of which the abovementioned repayment is optimized and a suspension of the motor is ensured transversely to the direction of travel.
Diese Aufgabe wird bei einem Triebdrehgestell der eingangs erwähnten Art erfindungsgemäß durch die Maßnahme nach dem kennzeichnenden Teil des Patentanspruches 1 gelöst. Durch die Kombination der Federaufhängung mit dem Dämpfer wird eine Tilgung des gesamten Schwingungssystems herbeigeführt.This object is achieved in a motor bogie of the type mentioned in the invention by the measure according to the characterizing part of patent claim 1. By combining the spring suspension with the damper, the entire vibration system is eradicated.
Weiterere Vorteile der Erfindung werden durch die Maßnahmen nach den Ansprüchen 2 und 3 erreicht.Further advantages of the invention are achieved by the measures according to

In den Figuren ist mit 1 der Drehgestellrahmen bezeichnet, in welchem zwei Radsätze 2 und 3 in üblicher Weise gelagert sind, und durch je einen Fahrmotor 21 angetrieben werden. Bei der vorliegenden Erfindung wird zur Erzielung einer möglichst hohen Grenzgeschwindigkeit neben dem Einbau von Schlingerdämpfern zwischen Lokkasten und Triebdrehgestell auch der in der Technik allgemein als Tilgung bekannte Effekt herangezogen. Wie Fig. 1 zeigt, dienen als Tilger die beiden Fahrmotoren 21 mit ihren Getrieben 28, die mit Feder- und Dämpferelementen in horizontaler Richtung quer zur Fahrzeuglängsachse mit dem Drehgestellrahmen 1 verbunden sind. Diese sogenannte elastische Motoraufhängung kann auftretende Quer- und Drehschwingungen um die Hochachse 20 des Triebdrehgestelles tilgen, wodurch die Stabilität des Fahrzeuges eine entscheidende Verbesserung erfährt.In the figures, 1 denotes the bogie frame, in which two
Jeder der beiden Motore 21 ist an drei Punkten am Rahmen 1 aufgehängt. Der Punkt am Kopfträger 22 des Drehgestellrahmens wird als Gelenk 23 ausgebildet, das Drehungen des Motors um seine Hochachse, d.h. um eine quer zur Fahrtrichtung gelegene Achse zuläßt. Die beiden anderen Aufhänungspunkte 6,7 befinden sich am Querträger 24 des Drehgestellrahmens 1. Von diesen führen je zwei als doppelseitig eingespannte Biegebalken ausgebildete Blattfedern 25,25' senkrecht zu den Einspannpunkten 8,9 am Motor 21 (Fig. 4).Each of the two
Fig. 5 zeigt die Einspannung der Federn 25, 25' im Querträger 24 des Drehgestellrahmens 1. Die Federn 25, 25' besitzen an ihrem oberen Ende eine Riffelung 32, der eine Gegenriffelung in einem Querbalken 33 des Querträgers 24 gegenüberliegt. Durch Keile 34 werden die Federn mit der Riffelung gegen die Riffelung des Querbalkens 33 gedrückt, sodaß eine Art Spanneinheit entsteht. Die beiden Keile 34 sind durch mindestens einen Querbalken 35 (Fig. 2) verbunden, die mit einer Schraubverbindung 36 mit dem Querbalken 33 verspannt sind.5 shows the clamping of the
Diese Art der Konstruktion erlaubt eine exakte Einstellung der aus Stabilitätsberechnungen abgeleiteten Feder- und Dämpferkennwerte. Zwischen Motor 21 und Rahmen ist in Querrichtung zur Längsachse des Fahrzeuges ein hydraulischer Dampfer 26 eingebaut (Fig.1). Die Tilgung baut somit auf der Querfederrate mit dem dazu angeschlossenen hydraulischen Querdämpfer 26 auf.This type of construction allows an exact setting of the spring and damper parameters derived from stability calculations.
