Abstract

A brake system damping device includes a first space to which hydraulic pressure is to be applied, a second space in which a compressible medium is situated, and a first separation element configured to separate the first space from the second space. The brake system damping device further includes a third space in which a compressible medium is situated and a second separation element configured the second space from the third space. The second space is connected in medium-conducting terms to the third space by a passage configured in the second separation element. The third space and the second separation element having the passage thereof are configured by an integral component.

First claim

What is claimed is:

1. A brake system damping device, comprising:
a first space to which a hydraulic pressure is to be applied;
a second space in which a compressible medium is situated;
a first separation element configured to separate the first space from the second space;
a cover; and
a second separation element,
wherein the cover and the second separation element define a third space in which the compressible medium is situated,
wherein the second separation element is configured to separate the second space from the third space,
wherein the second separation element defines a passage configured to connect the second space to the third space,
wherein the cover and the second separation element are an integral component, and
wherein the second space and the third space are isolated from the atmosphere.

2. The brake system damping device according to claim 1 , wherein the second separation element has a separation element internal wall which, in a longitudinal section of the second space, extends in an arcuate manner toward the passage.

3. The brake system damping device according to claim 1 , wherein the first separation element includes a membrane.

4. The brake system damping device according to claim 1 , wherein:
the first separation element, at least in portions, is configured as a disk having a circular shape, and wherein
the first separation element has a circular membrane curvature that is disposed so as to be concentric with a center of the circular shape.

5. The brake system damping device according to claim 1 , wherein:
the second space is delimited by an internal wall of the second separation element that is disposed so as to be opposite the first separation element, and
the internal wall defines a bowl-shape.

6. The brake system damping device according to claim 1 , wherein the cover is configured to hold the first separation element in a housing of the brake system.

7. The brake system damping device according to claim 3 , wherein the membrane is a roll membrane.

8. A brake system damping device, comprising:
a first space to which a hydraulic pressure is to be applied;
a second space in which a compressible medium is situated;
a first separation element configured to separate the first space from the second space;
a third space in which a compressible medium is situated; and
a second separation element configured to separate the second space from the third space,
wherein the second space in medium-conducting terms is connected to the third space by a passage configured in the second separation element,
wherein the first separation element is configured so as to be movable and by way of the movement thereof so as to be supported on the second separation element, and
wherein the movement of the first separation element, in at least one direction, is configured to compress the compressible medium in the second space and the third space.

9. The brake system damping device according to claim 8 , wherein the first separation element, by way of the movement thereof is configured to bear in a holohedral manner on the second separation element.

10. The brake system damping device according to claim 8 , wherein the second space, by way of the movement of the first separation element, is configured to be reduced in size concentrically toward the passage.

11. The brake system damping device according to claim 8 , wherein the second space, by way of the movement of the first separation element, is configured to be completely emptied.

12. The brake system damping device according to claim 8 , wherein the second separation element has an internal wall which, in a longitudinal section of the second space, extends in an arcuate manner toward the passage.

13. The brake system damping device according to claim 8 , wherein the first separation element includes a membrane.

14. The brake system damping device according to claim 13 , wherein the membrane is a roll membrane.

15. The brake system damping device according to claim 8 , wherein:
the first separation element, at least in portions, is configured as a disk having a circular shape, and wherein
the first separation element has a circular membrane curvature that is disposed so as to be concentric with a center of the circular shape.

16. The brake system damping device according to claim 8 , wherein:
the second space is delimited by an internal wall of the second separation element that is disposed so as to be opposite the first separation element, and
the internal wall defines a bowl-shape.

17. The brake system damping device according to claim 8 , wherein:
the third space and the second separation element are defined by a component, and
the component is configured to hold the first separation element in a housing of the brake system.
