Patent ID: 8113327

Claim:
A multiple clutch assembly, comprising: at least first ( 5 , 9 ) and second ( 7 , 11 ) friction devices; at least first ( 15 ) and second ( 17 ) plates provided for pressing on the respective first and second friction devices; at least first ( 21 ) and second ( 25 ) diaphragms for actuating the respective first and second plates, each of the diaphragms being able to move between a disengaged ( 21 a , 25 a or 25 b ) position and an engaged position ( 21 b or 21 c , 25 c ); the first diaphragm ( 21 ) approaching the second diaphragm ( 25 ) when it passing from the disengaged position to the engaged position thereof; and at least first ( 23 ) and second ( 27 ) actuating means for actuating the respective diaphragms, the second actuation means ( 27 ) comprising travel take-up means for taking-up the travel of the second diaphragm ( 25 ) so that the second diaphragm ( 25 ) covers a predetermined travel between the disengaged ( 25 a , or 25 b ) and engaged ( 25 c ) positions independently of the degree of wear on the second friction device ( 7 , 11 ); the travel take-up means comprising memorization means for memorizing the predetermined travel of the second diaphragm ( 25 ) between the disengaged ( 25 a or 25 b ) and engaged ( 25 c ) positions thereof prior to setting the pressure plates ( 15 , 17 ) in rotation when the second friction device being in a new state, and for adjusting the disengaged position of the second actuation means ( 27 ) so that the diaphragm ( 25 ) covers the memorized predetermined travel after setting the pressure plates ( 15 , 17 ) in rotation.
