Abstract
Elastomere Hydro-Lager zum beidseitigen Einsatz in Achslenklagern für Schienenfahrzeuge, bestehend aus einem mit einem Elastomer (3) ummantelten metallischen Innenbolzen (1), welcher seinerseits von einer anvulkanisierten zweiteiligen Zwischenhülse (2) in Halbschalenform so umgeben ist, dass sich aufgrund der Form des Elastomers (3) zwischen diesem und der Innenseite der Zwischenhülse (2) zwei symmetrische, sich diametral gegenüberliegende, mit intern durch Drossel-Kanäle (13) und hierin befindlichen einstellbaren Drosselelementen (6) verbundene Kammern (11, 12) bilden, welche zur Aufnahme der hydraulischen Dämpfungsflüssigkeit dienen, sowie einer über die Zwischenhülse (2) gezogenen Außenhülse (4) für die Befüllung mit hydraulischer Dämpfungsflüssigkeit, wobei die Außenhülse (4) ein definiertes Passmaß des Innendurchmessers sowie beidseitige Bördelung aufweist und so eine relative Radialverlagerung des Innenbolzens (1) zur Außenhülse (4) hin ermöglicht und je nach Kennlinie die Bewegung in Abhängigkeit der Dämpfung bzw. Steifigkeit beeinflusst wird, dadurch gekennzeichnet, dass die Hydroflüssigkeitsbestandteile zwischen den Kammern (11, 12) durch die von einstellbaren Drosselelementen (6) gesteuerten Drossel-Kanäle (13) so verlagert werden können, dass eine Veränderung der dynamischen Federrate mittels der dadurch verursachten Resonanz mit Phasenverschiebung bewirkt wird.Elastomeric hydraulic bearings for double-sided use in axle pivot bearings for rail vehicles, consisting of a metallic inner bolt (1) coated with an elastomer (3), which in turn is surrounded by a vulcanized two-part intermediate sleeve (2) in a half-shell shape so that due to the shape of the Elastomers (3) between this and the inside of the intermediate sleeve (2) form two symmetrical, diametrically opposed chambers (11, 12), which are connected to the internally connected by throttle channels (13) and adjustable throttle elements (6), which contain serve the hydraulic damping fluid, as well as an outer sleeve (4) drawn over the intermediate sleeve (2) for filling with hydraulic damping fluid, the outer sleeve (4) having a defined fit of the inner diameter and flanging on both sides and thus a relative radial displacement of the inner bolt (1) to the outer sleeve (4) and depending nac h characteristic curve, the movement is influenced as a function of the damping or rigidity, characterized in that the hydraulic fluid components between the chambers (11, 12) can be displaced by the throttle channels (13) controlled by adjustable throttle elements (6) so that a Change in the dynamic spring rate by means of the resulting resonance with phase shift.
Description
Die Erfindung betrifft elastomere Hydro-Lager (Buchsen) mit interner und/oder externer hydraulischer Dämpfung für die Verwendung in Achslenkerlagern. Achslenklager als hydraulische Hydro-Lager sind aus dem Automobilbereich bekannt und werden auch für den Einsatz in Schienenfahrzeugen einschließlich den zugehörigen Hydro-Lagern beschrieben, z. B. in
Darüber hinaus ist es wünschenswert, das hydraulische Kammersystem dieser Hydro-Lager dauerhaft in Hinblick auf die enormen, wechselnden Belastungen im Schienenverkehr durch Temperaturschwankungen und extreme Schlag- und Druckeinwirkungen zuverlässig abzudichten, um den Austritt der Dämpfungsflüssigkeit und das wegen des Dieseleffektes schädliche Eindringen von Luft zu verhindern.
Aufgabe der Erfindung ist es daher, Hydro-Lager für Achslenklager für Schienenfahrzeuge mit langer Lebensdauer bereitzustellen, die kostengünstig herzustellen sowie einfach zu montieren, zu warten und zu reparieren sind und welche sowohl gegen Austreten von Dämpfungsflüssigkeit wie auch gegen mögliches Eindringen von Luft in allen Betriebszuständen sicher geschützt sind, sodass auch Leckageüberwachungs- und -anzeigevorrichtungen überflüssig werden.
Dies wird durch die erfindungsgemäßen Hydro-Lager mit interner und/oder externer hydraulischer Dämpfung im Zweikammerprinzip erreicht. Diese bestehen aus einem metallischen Innenbolzen (
In addition, it is desirable to reliably seal the hydraulic chamber system of these hydraulic bearings permanently in view of the enormous, changing loads in rail traffic due to temperature fluctuations and extreme impact and pressure effects, in order to prevent the damping fluid from escaping and the harmful penetration of air due to the diesel effect prevent.
The object of the invention is therefore to provide hydraulic bearings for axle steering bearings for rail vehicles with a long service life, which are inexpensive to manufacture and easy to assemble, maintain and repair and which protect both against leakage of damping fluid and against the possible penetration of air in all operating states are securely protected so that leakage monitoring and display devices are also superfluous.
This is achieved by the hydraulic bearing according to the invention with internal and / or external hydraulic damping in the two-chamber principle. These consist of a metallic inner bolt (

Ferner werden durch die variablen, radial verlagerbaren Innenbolzen über die internen Drossel-Kanäle (
Gegenüber den bereits bekannten Hydro-Lagern ist das vorliegende Lager in seinem modularen Aufbau sehr variabel. Es kann verschiedensten, vorstehend näher beschriebenen Anforderungen angepasst werden.Compared to the already known hydraulic bearings, the present bearing is very variable in its modular structure. Various requirements described in more detail above can be adapted.
