Abstract
A membrane for a hydraulically damping mount includes a first leg, a second leg and a base interconnecting the two legs. In embodiments, in an average thickness of one of the two legs is at least twice as thick as that of the other leg. A hydraulically damping mount with such a membrane is also disclosed.
Claims15
A membrane for a hydraulically damping mount, the membrane comprising:
- a first leg,
- a second leg, and
- a base interconnecting the two legs, the base having an approximately U-shaped cross section,
- wherein the first leg and the second leg protrude from the base,
- wherein, in a horizontal orientation of the membrane, the U-shaped cross section of the base comprises a reversing point at which the mathematical derivative of a geometric function describing a surface of the base equals zero,
- wherein, in the horizontal orientation, all portions of the two legs are arranged on one axial side of the reversing point,
- wherein an average thickness of one of the two legs is at least twice as thick as that of the other leg,
- wherein the cross section of the leg that is, on average, twice as thick continuously expands starting from the base, and
- wherein the leg that is, on average, twice as thick forms a radially outer leg, and is twice as long as the other leg.
