Claim:
An assembly ( 1 , 30 , 50 ) for activating first and second friction shifting elements ( 2 , 3 ) by a pressure, the assembly comprising: the first friction shifting element ( 2 ) comprising a first disc packet ( 8 ) with a first servo device ( 4 ) associated therewith and the second friction shifting element ( 3 ) comprising a second disc packet ( 9 ) with a second servo device ( 5 ) associated therewith, and each of the first and the second disc packets ( 8 , 9 ) comprising inner discs ( 10 , 11 ) and outer discs ( 12 , 13 ) secured to disc carriers ( 14 , 15 ), and the first and second disc packets ( 8 , 9 ) being positioned axially adjacent each other within the transmission; the inner discs ( 10 , 11 ) of the first and the second disc packets ( 8 , 9 ) are supported by a radially outwardly facing surface of a common inner disc carrier ( 16 ); the inner disc carrier ( 16 ) comprises a radial pot base ( 26 ) and a common annular surface, connected with a periphery of the pot base ( 26 ), which supports the inner discs ( 10 , 11 ) of both the first and the second disc packets ( 8 , 9 ) and the pot base ( 26 ) and the common annular surface form a pot-shaped structure which is axially opened on one end; the respective first and second servo devices ( 4 , 5 ) are both located primarily within a pot space ( 27 ) defined by the pot-shaped structure of the inner disc carrier ( 16 ) as well as at least partially axially adjacent each other and radially inward of the first and the second disc packets ( 8 , 9 ) of the first and the second friction shifting elements ( 2 , 3 ); the first friction shifting element ( 2 ) is located adjacent the pot base ( 26 ) of the inner disc carrier ( 16 ); the first and the second friction shifting elements ( 2 , 3 ) are activated individually and independent of each other by the respective first and second servo devices ( 4 , 5 ); the inner disc carrier ( 16 ), for both of the first and the second friction shifting elements ( 2 , 3 ), has radial openings ( 21 , 22 , 23 , 36 , 37 , 53 , 58 , 59 ) distributed on a circumference thereof in an axial area between both the disc packets ( 8 , 9 ); the inner discs ( 11 ) of the second disc packet ( 9 ) of the second friction shifting element ( 3 ) has axial openings ( 43 ), and the inner disc carrier ( 16 ) has axially aligned recesses distributed on the circumference at least in the area of the second disc packet ( 9 ) of the second friction shifting element ( 3 ); the axial openings ( 43 ) in the inner discs ( 11 ) of the second friction shifting element ( 3 ) or the recesses in the inner disc carrier ( 16 ) forms a penetration area through which axially aligned fingers ( 35 ) are guided, the axially aligned fingers are associated with the first servo device ( 4 ) of the first friction shifting element ( 2 ); and the axial aligned fingers ( 35 ) are provided to activate the first friction shifting element ( 2 ) and penetrate the axial openings ( 43 ) in the inner discs ( 11 ) of the second friction shifting element ( 3 ).
