Patent ID: 8540066

Claim:
A rotationally fixed connection of first and second components ( 2 , 4 ) of a transmission ( 1 ) for torque transfer, the first and second components ( 2 , 4 ) being coupled to one another by mating base surfaces supporting the rotationally fixed connection, and the first and second components ( 2 , 4 ) each comprising a cylindrical section which extends away from the mating base surfaces, the cylindrical section of the first component extends in a first axial direction and the cylindrical section of the second component extends in a second axial direction opposite the first axial direction and the rotationally fixed connection comprising: a combination of a mating pair of a first type of connection elements ( 6 , 8 ) and a mating pair of a different second type of connection elements ( 7 , 9 ), the mating first type of connection elements ( 6 , 8 ) ensuring torque transfer and mutual centering of the first and the second components ( 2 , 4 ) to be connected, but without restraining the first and the second components ( 2 , 4 ) from axially separating from one another, while the mating second type of connection elements ( 7 , 9 ) enabling axial fixing of the first and the second components ( 2 , 4 ) to prevent axial separation of the first and the second components ( 2 , 4 ) from one another and transfer of axial operating forces, a plurality of first members ( 6 ) of the first type of connection elements and a plurality of first members ( 7 ) of the second type of connection elements both being formed integrally with a first one of the first and the second components ( 2 , 4 ), and a plurality of mating second members ( 8 ) of the first type of connection elements and a plurality of mating second members ( 9 ) of the second type of connection elements both being formed integrally with a second one of the first and the second components ( 2 , 4 ).
