Abstract

A bushing for the force-fitting connection to a force-fitting partner, with a hollow-cylindrical basic body, with the basic body defining a primary axis, with the basic body comprising at least one coupling section with at least one radially extending penetrating opening for a fluidic communication with a fluid section in the force-fitting partner, and with the wall thickness in the coupling section being greater than the wall thickness in the neighboring section of the basic body abutting the coupling section with the basic body showing a track section, extending in the circumferential direction, for supporting a radial guidance of a bearing partner, and a transmission arrangement comprising the bushing.

First claim

What is claimed is:

1. A bushing for a force-fitting connection to a force-fitting partner, the bushing comprising:
a hollow-cylindrical basic body defining a primary axis, the hollow-cylindrical basic body comprising:
at least one coupling section having at least one radially extending penetrating opening for a fluidic communication with a fluid section in the force-fitting partner, the at least one coupling section having a first wall thickness;
a neighboring section abutting said at least one coupling section, the neighboring section having a second wall thickness; and,
a track section for a bearing extending in a circumferential direction for a radial guidance of a bearing partner, the track section having a third wall thickness; wherein:

the first wall thickness is larger than the second wall thickness and the third wall thickness; and,
the third wall thickness is equivalent to the second wall thickness.

2. The bushing recited in claim 1 , wherein the hollow-cylindrical basic body comprises at least one sealing section extending in the circumferential direction.

3. The bushing recited in claim 1 , wherein the track section is arranged at a free end of the hollow-cylindrical basic body.

4. The bushing recited in claim 1 , wherein the bushing is embodied as a drawn sheath.

5. The bushing recited in claim 4 , wherein the drawn sheath is embodied as a drawn sheath with a flange end and a tension end, with the track section being arranged at the tension end.

6. A transmission arrangement for a vehicle, comprising:
a bushing arranged for a force-fitting connection to a force-fitting partner, the bushing comprising:
a hollow-cylindrical basic body defining a primary axis, the hollow-cylindrical basic body comprising:
at least one coupling section having at least one radially extending penetrating opening for a fluidic communication with a fluid section in the force-fitting partner; and,
a track section for a bearing extending in a circumferential direction for a radial guidance of a bearing partner; wherein:
a first wall thickness in the coupling section is larger than a second wall thickness in a neighboring section of the hollow-cylindrical basic body abutting the at least one coupling section;

wherein the bearing is arranged between the bearing partner and the bushing, such that they are rotational in reference to each other about the primary axis; and,
wherein the bushing is connected via a press fit to the force-fitting partner.

7. The transmission arrangement recited in claim 6 , wherein the bearing partner provides a counter track for the roller bearing device, with the counter track being formed in the bearing partner.

8. The transmission arrangement recited in claim 6 , wherein the bearing partner is embodied as a shaft and the force-fitting partner as a shaft support.

9. The transmission arrangement recited in claim 8 , wherein the shaft is embodied as a drive shaft and the shaft support is formed as a guide wheel section.

10. A bushing for a force-fitting connection to a force-fitting partner, said bushing comprising:
a hollow-cylindrical basic body defining a primary axis, said hollow-cylindrical basic body comprising:
at least one coupling section extending axially along the primary axis and limited in a circumferential direction about the primary axis, the at least one coupling section comprising:
a first wall thickness; and,
a radially extending penetrating opening arranged for a fluidic communication with a fluid section in said force-fitting partner;

a neighboring section abutting said at least one coupling section, said neighboring section having a second wall thickness where said second wall thickness is smaller than said first wall thickness; and,
a track section for a bearing extending in the circumferential direction for radially guiding a bearing partner.
