Abstract
The invention relates to a multiple clutch assembly comprising: first (5, 9) and second (7, 11) friction elements; first (15) and second (17) plates for applying pressure to said respective friction elements; first (21) and second (25) diaphragms for actuating said respective plates, each diaphragm being mobile between a disengaged position (21a, 25a or 25b) and an engaged position (21b or 21c, 25c), said first diaphragm (21) approaching the second diaphragm (25) when it passes from the disengaged position thereof to the engaged position thereof; and first (23) and second (27) means for actuating said respective diaphragms. Said second actuating means (27) comprise means for renewing the course of the second diaphragm (25), in such a way that the second diaphragm (25) follows a pre-determined course between the disengaged position (25a or 25b) and the engaged position (25c) thereof, independently of the degree of wear of the second friction element (7, 11).
