Description
Es ist bekannt, an Straßenbahnwagen den Elektromotor auf einer Querschiene zu lagern, die an ihren beiden Enden auf Schraubenfedern ruht, um die Schwingungen des Motors zu dämpfen. Dabei ist gleichzeitig unter Vermittlung von Pendeln an .eine gewisse Schwingungsmöglichkeit der Motortragschiene in der Quer- und Längsrichtung gedacht. Bekannt ist ferner die unmittelbare Lagerung des Motorgehäuses auf Blattfedern, um Stöße vom Motor möglichst fernzuhalten.It is known to mount the electric motor on a cross rail on trams, which rests on coil springs at both ends to control the vibrations of the engine dampen. At the same time, through the mediation of pendulums, there is a certain possibility of oscillation of the engine mounting rail in the transverse and longitudinal direction. The direct mounting of the motor housing is also known on leaf springs to keep shocks away from the engine as much as possible.
Im Falle der Erfindung ist der Elektromotor ebenfalls abgefedert pendelnd gelagert, und zwar aufgehängt. Der Erfindung liegt im be- -i5 sonderen die Aufgabe zugrunde, eine derartige Aufhängung für Triebwagen oder Triebgestelle geeignet zu machen, bei denen der Motor mittels Tatzenlagern auf einer seitlich verschiebbaren Triebachse des Triebwagens oder des Triebao gestelies ruht. Zur Lösung der Aufgabe ist der Motor unter Vermittlung einer Blattfeder an Dreieckspendeln aufgehängt. An sich sind Dreieckspendel im Waggonbau zur Aufhängung von schwingenden Teilen bekannt. Durch die Anwendung der beiden Mittel wird besonders erreicht, daß die Querschwingungen des Elektromotors sowohl durch die Dreieckspendel als auch durch die innere Reibung der Blattfeder gedämpft werden und der Motor daher ruhiger im Fahrzeug liegt.In the case of the invention, the electric motor is also mounted in a sprung pendulum fashion, and although hung up. The invention is based in particular on the object of such To make suspension suitable for railcars or motor bogies, in which the engine means Paw bearings on a laterally movable drive axle of the railcar or the Triebao gestelies rests. To solve the problem, the engine is switched on by means of a leaf spring Suspended triangular pendulums. Triangular pendulums are in wagon construction for suspension known from vibrating parts. Using both means becomes special achieved that the transverse vibrations of the electric motor both by the triangular pendulum as can also be dampened by the internal friction of the leaf spring and the engine is therefore quieter is in the vehicle.
Abb. ι veranschaulicht schematisch an einem Ausführungsbeispiel das sich im Falle der Erfindung ergebende Bild.Fig. Ι illustrates schematically in an embodiment that is in the case of the invention resulting image.
a, b und c sind die Eckpunkte der am Rahmen d aufgehängten Dreieckspendel, die an ihren unteren Eckpunkten c gemäß der Erfindung durch eine Blattfeder e miteinander verbunden sind. Die Anordnung kann auch umgekehrt getroffen sein, also, die Spitze des Dreiecks im Rahmen d Hegen. a, b and c are the corner points of the triangular pendulums suspended on the frame d , which are connected to one another at their lower corner points c according to the invention by a leaf spring e. The arrangement can also be made the other way round, that is, the apex of the triangle in the frame d Hegen.
Die Dreieckspendelaufhängung vereinigt in bekannter Weise die Vorzüge der lotrechten und der schrägen Pendelaufhängung, nämlich der Rückstellkraft und der parallelen Verschiebung der Aufhängepunkte bzw. des diese verbindenden Gliedes, im Falle der Erfindung also der Blattfeder e. Im vorliegenden Falle äußert sich dies in der Weise, daß eine Verwindung der Blattfeder beim Ausschwingen der Pendel vermieden wird.The triangular pendulum suspension combines in a known manner the advantages of the vertical and the oblique pendulum suspension, namely the restoring force and the parallel displacement of the suspension points or the link connecting them, in the case of the invention the leaf spring e. In the present case, this is expressed in such a way that twisting of the leaf spring when the pendulum swings out is avoided.
Abb. 2 zeigt die Aufhängung gemäß Abb. 1 unter näherer Darstellung der betreffenden Teile.Fig. 2 shows the suspension according to Fig. 1 with a more detailed representation of the relevant Parts.
f ist der Federbund," der mittels eines Ansatzes g zwischen zwei an dem nicht weiter dargestellten Motorgehäuse festen Lappen h greift und der durch einen Bolzen i gelenkig mit diesem Lappen verbunden ist. j sind die Pendelglieder, die zur Erzielung der Dreieckspendelaufhängung dienen.' f is the spring collar "which, by means of a shoulder g , engages between two tabs h fixed to the motor housing (not shown) and which is articulated to this tab by a bolt i . j are the pendulum links that serve to achieve the triangular pendulum suspension.
