Abstract

A profiled clamp having a first profiled clamp half and a second profiled clamp half, by means of which two flange parts can be connected to each other while applying an axial force, wherein a first tightening head is formed at an end of the first clamp half and a second tightening head is formed at an end of the second clamp half in order to form a tightening device. The ends of the clamp halves opposite the tightening heads are connected to each other by means of an articulated connection. The articulated connection is formed by means of a flat strip section.

First claim

The invention claimed is:

1. A profiled clamp for use in a motor vehicle turbocharger system having a first profiled clamp half and having a second profiled clamp half, by way of which two flange parts are connectable together thereby applying an axial force, wherein, for forming a tightening device, a first tightening head is realized at one end of the first clamp half and a second tightening head is realized at one end of the second clamp half, wherein the ends of the clamp halves located opposite the tightening heads are connected together by means of an articulated connection, wherein the articulated connection is formed by means of a flat strip portion, wherein a hole is introduced into the flat strip portion, and wherein, the flat strip portion comprises a tapering constituted by lateral edge incisions compared to an initial width of the profiled clamp halves, the initial width of the profiled clamp halves being greater than the width of the flat strip portion.

2. The profiled clamp as claimed in claim 1 , wherein the hole is realized in a round, angular or oval manner.

3. The profiled clamp as claimed in claim 2 , wherein the hole comprises a dimension of between approximately 3 mm and 8 mm in a main direction, wherein a secondary direction located transversely with respect to the main direction comprises a dimension of between approximately 2 mm and 4 mm.

4. The profiled clamp as claimed in claim 1 , wherein the first tightening head comprises a rectangular passage, through which a screw element with a complementarily realized rectangular shoulder is insertable.

5. The profiled clamp as claimed in claim 4 , wherein pressing lugs, which move to bear against one another when the screw element is tightened, are realized on the end faces of the tightening heads.

6. The profiled clamp as claimed in claim 4 , wherein the screw element is screw-connected with a self-locking nut.

7. The profiled clamp as claimed in claim 1 , wherein the flat strip portion is a one-piece extension of the first profiled clamp half and second profiled clamp half, and extends between the first and second profiled clamp halves.
