A sealing sleeve for a transmission or a clutch of a motor vehicle for use between two torque transmitting devices, which rotate relative to each other, wherein a shell surface of the sealing sleeve is designed for making contact in a sliding and sealing manner with one or more sealing means; and a flange section, which projects radially from the shell surface, is designed for interpositioning between the two torque transmitting devices, wherein the flange section is formed as a running surface for an axial bearing. An automatic transmission or a clutch with a first torque transmitting device and a second torque transmitting device, between which an inventive sealing sleeve is inserted.

Sealing sleeve with combined axial bearing and automatic transmission or clutch with such a sealing sleeve

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.

Bushing and transmission arrangement with the bushing

A bearing position for a torque converter, wherein a pump impeller is connected to a converter neck, and the pump impeller is rotatably mounted on the bearing position by at least one roller bearing in a housing, wherein the roller bearing comprises an outer rolling raceway, assigned to the converter neck and facing radially outwards, and an inner rolling raceway, assigned to the housing and facing radially inwards, and rollers disposed radially between the rolling raceways, wherein the bearing position comprises at least one radially elastically designed section of a sleeve of the roller bearing, where the sleeve is provided with the inner rolling raceway, wherein the section, enclosing an elastic convex raceway curvature, is resiliently prestressed in the radial direction against at least a first roller of the rollers, the first roller supported on the outer rolling raceway, and supported in the opposite radial direction on the housing.

A ring element, particularly a thrust bearing race ring, which has a peripheral wall, through which a radial load exerting an interference fit occurs. The peripheral wall is configured such that it forms zones with a large overlap and zones with a reduced overlap that succeed each other in a peripheral direction.

A bearing pin for a planetary transmission, which has a cylindrical base body with a radial bore formed in one axial end of the base body. A locking element is mounted with a salient radial portion in the radial bore and serves as an anti-rotation feature of the base body. The bearing pin creates a possibility of reliable fixing of a bearing pin in a planetary transmission with a low-complexity manufacturing procedure. Also, a carrier arrangement for a planetary transmission, which includes such a bearing pin is disclosed.

A raceway bushing which has a substantially cylindrical peripheral wall that forms a bushing inner surface and a bushing outer surface, a bottom wall which extends from the peripheral wall and has an inner bottom surface and an outer bottom surface, and a bottom opening configured in the bottom wall. The bottom opening is bordered by an annular collar that rises axially beyond the inner bottom surface.

Drawn bushing, particularly in form of a raceway bushing for an automatic transmission

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.
