Abstract
(DE)
Die Erfindung betrifft eine Dämpfungseinrichtung (10) für ein Kraftfahrzeug, insbesondere zur Dämpfung von An- und Abstellschlägen eines Kraftfahrzeugmotors (47), mit einer ersten und zweiten Kammer (14, 17), die mit einem Dämpfungsmedium (18) gefüllt sind und durch eine Zwischenplatte (11) getrennt sind, wobei die Kammern (14, 17) jeweils durch einen Faltenbalg (12, 15) und durch eine Stirnplatte (13, 16) begrenzt sind, wobei in der Zwischenplatte (11) ein die Kammern (14, 17) verbindender Dämpfungskanal (19) eingebracht ist. Um eine Dämpfungswirkung abhängig vom Betriebszustand des Kraftfahrzeugmotors (40) zu erzielen, wird erfindungsgemäß vorgeschlagen, dass die beiden Kammern (14, 17) mit wenigstens einem Bypasskanal (20) verbunden sind, wobei der Bypasskanal (20) mittels eines schaltbaren Ventils (22, 51, 54) freigebbar oder verschließbar ist und wobei der Schaltzustand des Ventils (22, 51, 54) vom Betriebszustand des Kraftfahrzeugs abhängt. Zudem betrifft die Erfindung ein Dämpfungssystem (40) zur Dämpfung von An- und Abstellschlägen eines Kraftfahrzeugmotors (47).
(EN)
The invention relates to a damping device (10) for a motor vehicle, particularly for damping starting and stopping impacts of a motor vehicle engine (47), having a first and second chamber (14, 17) filled with a damping medium (18) and separated by an intermediate plate (11), wherein the chambers (14, 17) are each bounded by a bellows (12, 15) and by a face plate (13, 16), wherein a damping channel (19) connecting the chambers (14, 17) is implemented in the intermediate plate (11). In order to achieve a damping effect depending on the operating mode of the motor vehicle engine (40), the invention proposes that the two chambers (14, 17) are connected by at least one bypass channel (20), wherein the bypass channel (20) can be opened or closed by means of a switchable valve (22, 51, 54) and wherein the switched state of the valve (22, 51, 54) depends on the operating mode of the motor vehicle. The invention further relates to a damping system (40) for damping the starting and stopping impacts of a motor vehicle engine (47).

L'invention concerne un dispositif amortisseur (10) pour un véhicule automobile, en particulier destiné à amortir les à-coups de démarrage et d'arrêt d'un moteur de véhicule automobile (47), avec une première et une deuxième chambre (14, 17) qui sont remplies d'un fluide amortisseur (18) et sont séparées par une plaque intermédiaire (11). Chacune des chambres (14, 17) est formée d'un soufflet (12, 15) et d'une plaque frontale (13, 16), la plaque intermédiaire (11) comprenant un canal amortisseur (19) qui relie les chambres (14, 17). Afin d'obtenir un effet d'amortissement qui dépend de l'état de fonctionnement du moteur de véhicule automobile (47), il est proposé, selon l'invention, que les deux chambres (14, 17) soient reliées par au moins un canal de dérivation (20), le canal de dérivation pouvant être dégagé ou obturé à l'aide d'une vanne asservie (22, 51, 54) et l'état de fonctionnement de la vanne (22, 51, 54) dépendant de l'état de fonctionnement du véhicule automobile. L'invention concerne en outre un système d'amortissement (40) pour l'amortissement des à-coups de démarrage et d'arrêt d'un moteur de véhicule automobile (47).
