Abstract

A bearing system, for bearing a motor vehicle assembly at a motor vehicle body, with a fluid operating chamber that is in flow connection, by way of at least one fluid channel, with a fluid equilibration chamber, which is present in a housing of the bearing system. The fluid operating chamber and the fluid equilibration chamber are separated by a separating element, in which the at least one fluid channel is present. The separating element is decoupled from the housing by an elastic element, which surrounds the separating element in the peripheral direction. The housing has a cover, which accommodates the fluid equilibration chamber, and a supporting part, which holds a spring element of the bearing system.

First claim

The invention claimed is:

1. A bearing system comprising:
in particular for bearing a motor vehicle assembly at a motor vehicle body, a fluid operating chamber that is in flow connection, by way of at least one fluid channel, with a fluid equilibration chamber, which is present in a housing of the bearing system, wherein the fluid operating chamber and the fluid equilibration chamber are separated by a separating element, in which the at least one fluid channel is present, wherein the separating element is decoupled from the housing by means of an elastic element, which surrounds the separating element in the peripheral direction, wherein the housing has a cover, which accommodates the fluid equilibration chamber, and a supporting part, which holds a spring element of the bearing system, wherein the cover engages between the supporting part and the elastic element in such a way that, as viewed in the radial direction with respect to a central longitudinal axis of the bearing system, the elastic element, the cover, and the supporting part follow one another in succession, wherein an elastic membrane is fastened to the separating element, which membrane separates a fluid damping chamber rheologically from the fluid operating chamber, wherein the fluid damping chamber is in flow connection, by way of a throttle channel, with an outer surrounding of the bearing system, wherein the fluid damping chamber is arranged in the separating element, and wherein the throttle channel is arranged in a protrusion, which is at least annularly encompassed by the fluid equilibration chamber and protrudes towards the separating element.

2. The bearing system according to claim 1 , wherein the elastic element, together with the separating element, encloses the fluid equilibration chamber.

3. The bearing system according to claim 1 , wherein the separating element is fastened to the housing by way of the elastic element.

4. The bearing system according to claim 1 , wherein the spring element is fastened, by way of the supporting part, in a guide recess of a guide device, wherein the supporting part engages between the guide device and the cover in such a way that, as viewed in the radial direction with respect to the central longitudinal axis, the elastic element, the cover, the supporting part, and the guide device follow one another in succession.

5. The bearing system according to claim 1 , wherein the elastic element is arranged between the cover and the supporting part, in particular, in a clamped manner.

6. The bearing system according to claim 1 , wherein the supporting part engages over the cover in the axial direction in some regions and is fastened in a form-fitting manner to the cover.

7. The bearing system according to claim 1 , wherein the elastic element has a separating-element receiving groove for the separating element.

8. The bearing system according to claim 1 , wherein the separating element has a first part and a second part, wherein the two parts are fastened to each other, and/or both of them engage in a separating-element receiving groove.
