Abstract
The invention concerns an interference fit comprising a carrier and at least one stepped bushing seated with an interference fit on the carrier. The stepped bushing is made by shaping a sheet metal and is characterized by a special wall thickness configuration. Through this wall thickness configuration, it becomes possible to assure that the stepped bushing conforms to close shape tolerances in the pressed-in state in regions of functional relevance.

An assembly, comprising:
- a carrier having a surface with at least one depression configured on the surface;
- and
- at least one bushing-type component, which is made of sheet metal and seated with an interference fit on the carrier, having at least one wall section, which at least partially covers the depression, comprised of a first cylindrical wall section and a second cylindrical wall section, the first cylindrical wall section has a larger outer diameter than the second cylindrical wall section, and an annular shoulder section configured in an intermediate region between the first cylindrical wall section and the second cylindrical wall section,
- wherein a thickness of the sheet metal of the wall section of the bushing-type component by which the depression is covered at least partially is larger than a thickness of the sheet metal of the bushing-type component that directly adjoins the wall section in at least one direction such that the bushing-type component forms the interference fit with the carrier in surroundings of the depression.
The assembly according to claim 0, wherein the bushing-type component and the carrier are seated on each other with the interference fit in the surroundings of the depression, and in the surroundings of the depression, a thickness of the sheet metal of the wall section is larger than a thickness of the sheet metal of the bushing.
A medium guide in a transmission, comprising:
- a carrier having at least one depression configured on a surface of the carrier;
- at least one bushing-type component, which is made of sheet metal and seated with an interference fit on the carrier, having at least one wall section comprised of a first cylindrical wall section and a second cylindrical wall section, the first cylindrical wall section has a larger outer diameter than the second cylindrical wall section, and an annular shoulder section configured in an intermediate region between the first cylindrical wall section and the second cylindrical wall section;
- and
- at least one channel formed between the carrier and the bushing-type component that is capable of guiding mediums, said channel being formed by the wall section of the bushing-type component and by the depression which is at least partially covered by the wall section,
- the carrier and the bushing-type component forming an interference fit with each other, and the bushing-type component being configured as a stepped bushing.
A bushing-type component made of sheet metal, comprising:
- a first cylindrical wall section having a first diameter;
- and
- a second cylindrical wall section having a second diameter that is smaller than the first diameter of the first cylindrical wall section, first and second cylindrical wall sections being directed coaxially to an axis of rotation, and a radial sheet metal thickness of at least one wall section made by cold shaping out of the sheet metal is larger at least than a radial thickness of the sheet metal of a bushing that adjoins the wall section in both axial directions that are aligned to the axis of rotation.
