主权项

1. A selectively engagable dry friction clutch assembly for connecting a transmission with a flywheel of an engine comprising:
a cover having a main body axially spaced from said flywheel and being torsionally connected thereto; an axially movable pressure plate torsionally connected with said cover; a friction disc for having torsional connection with an input shaft of a transmission, said friction disc being axially positioned between said flywheel and said pressure plate; a release assembly including a spring for urging said pressure plate toward said flywheel; and an adjustment assembly juxtaposed between said pressure plate and said spring for compensating for wear of said friction disc, said adjustment assembly including:
a first cam ring fixed with respect to said pressure plate;a second cam ring juxtaposed between said spring and said first cam ring wherein rotation of said second cam ring with respect to said first cam ring changes an effective distance between said spring and an extreme end of said pressure plate;a torsional spring connected between said first and second cam ring to urge said second cam ring to rotate with respect to said first cam ring;a control finger frictionally connected with said pressure plate in an aperture of said pressure plate, said control finger having an extreme end for contact with said flywheel and a limiting end for restraining relative rotation of said second cam ring with respect to said first cam ring in an absence of wear of said friction disc; anda baffle connected with said second cam ring for shielding said torsion spring, said baffle having a tab for making contact with said control finger to limit relative rotation of said second cam ring with respect to said first cam ring.
