Abstract:
A multi-plate clutch mechanism, comprising:a first cylindrical portion configured for connection to a flywheel;a hub flange having a second cylindrical portion disposed concentrically within said first cylindrical portion, said hub flange configured to non-rotatably engage an input shaft of a transmission and to axially slide with respect to the input shaft;a plurality of first friction plates disposed between said first cylindrical portion and said second cylindrical portion, said first friction plates being circumferentially engaged for rotation with said first cylindrical portion but relatively slidable in the axial direction with respect to said first cylindrical portion;a plurality of second friction plates disposed alternatingly adjacent to said first friction plates in the axial direction, one of said second friction plates being engaged with said second cylindrical portion for rotation therewith but configured for limited relative axial movement with respect to said second cylindrical portion;a pressure plate mechanism fixed to said first cylindrical portion such that said friction plates are disposed between said pressure plate mechanism and the flywheel;a plate member fixed to said hub flange, said plate member confining said one of said second friction plates between said plate member and said hub flange limiting axial movement of said hub flange between said pressure plate and the flywheel; andwherein said one of said second friction plates having a radially inwardly protruding portion extending between said plate member and said second cylindrical portion.
