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. The clamping screw is threadable into the crankcase of the internal combustion engine. The disk spring includes a disk spring packet with at least four individual springs oriented opposite to one …
