Abstract

The invention relates to an elastic mount consisting of a core and a sleeve made of metal, between which is arranged a spring element made of rubber or rubber-like material. The significant point about this invention is that the metal-rubber bearing has two diametrically arranged elastic chambers (hydraulic end stops) filled with hydraulic fluid which are connected to one another by one or more flow passages.

Description

Die Erfindung betrifft ein elastisches Lager, insbesondere für den Kfz-Bereich, gemäß Oberbegriff des Anspruchs 1.The invention relates to an elastic bearing, in particular for the motor vehicle sector, according to the preamble of claim 1.

Das erfindungsgemäße elastische Lager unterscheidet sich von dem Standard-Metall-Gummi-Lager durch das Vorhandensein hydraulischer Endanschläge. Diese werden durch zwei diametral angeordnete, mit Hydraulikflüssigkeit gefüllte elastische Kammern, die mit einem oder mehreren Strömungskanälen miteinander verbunden sind, gebildet.The elastic bearing according to the invention differs from the standard metal-rubber bearing by the presence hydraulic end stops. These are diametrically separated by two arranged elastic filled with hydraulic fluid Chambers with one or more flow channels are interconnected.

Je nach der Geometrie des Strömungskanals und der kinematischen Viskosität der Hydraulikflüssigkeit werden unterschiedliche Durchtauchgeschwindigkeiten bei plötzlich auftretenden großen Belastungen erreicht. Das hat zur Folge, daß ab Eintritt der Kammeraktivitäten zusätzliche Verlustarbeit, u. z. in zeitlich verzögerter Form, eingeleitet wird.Depending on the geometry of the flow channel and the kinematic Hydraulic fluid viscosity will be different Immersion speeds in the case of suddenly occurring large ones Loads reached. As a result, from the time the Chamber activities additional loss work, u. e.g. in time delayed form, is initiated.

Die Erfindung wird im folgenden anhand eines Ausführungsbeispiels unter Bezugnahme zweier schematischer Zeichnungen erläutert. Dabei zeigtThe invention is described below using an exemplary embodiment explained with reference to two schematic drawings. It shows

Fig. 1 den Längsschnitt und Fig. 1 shows the longitudinal section and

Fig. 2 den Querschnitt des erfindungsgemäßen elastischen Lagers. Fig. 2 shows the cross section of the elastic bearing according to the invention.

Dabei besteht das elastische Lager (1) aus folgenden Teilen:
Metallkern (2)
Metallhülsen: Außenhülse (3 a)
Innenhülse (z. B. Kragenhülse) (3 b)
Kammern (4, 5), die mit Hydraulikflüssigkeit gefüllt sind Strömungskanal (6).The elastic bearing ( 1 ) consists of the following parts:
Metal core ( 2 )
Metal sleeves: outer sleeve ( 3 a )
Inner sleeve (e.g. collar sleeve) ( 3 b )
Chambers ( 4 , 5 ) which are filled with hydraulic fluid flow channel ( 6 ).
