  • Patent number: 5624099
    Abstract: An elastic mounting apparatus for vibration-decoupled mounting of a turbocharger housing on an internal combustion engine. The mounting apparatus includes a clamping element with two spring elements arranged in a functionally serial relationship. The clamping element joins the housing and the internal combustion engine so as to allow relative vibration between the two. The first spring element includes an annular spring member made of elastomeric material and a second spring element formed by at least one disk spring. The clamping element is penetrated by a clamping screw, and the disk spring can be compressed by the clamping screw in such a way that its spring rate, after compression to the intended preload, is substantially zero. The housing is configured as a turbocharger housing with at least one intake pipe. The intake pipe is braced in a vibration-decoupled and sealing manner on the cylinder head of the internal combustion engine by a sealing element made of an elastomeric material.

  • Patent number: 5540419
    Abstract: An elastic bearing includes a support and a thrust bearing. Each is provided with a fastening element and each are braced against each other by at least one elastic spring element of an elastomeric material and at least one damping device. The support includes a supporting body made of a tough material, which extends essentially transverse to the direction of the introduced vibrations. The thrust bearing includes a drum-shaped housing which essentially encloses the supporting body on all sides. The supporting body is adjoined by at least one ring-shaped damping element made of an elastomeric material which, under static preloading of the bearing, abuts on the front-side inner surfaces of the housing in a substantially stress-free manner. In the cylindrical recess of the damping element at least one elastic spring element is arranged axially on both sides of the supporting body.
