Adjusting mechanism for the intermediate plate in two disc clutches

Claim 1

A clutch adjusting mechanism having a driving clutch part, a pair of disk clutches, an intermediate plate disposed between said clutch disks operatively connected with said driving clutch part and being non-rotatable with respect thereto but axially displaceable therefrom. and means for automatically readjusting said intermediate plate corresponding to the wear of said clutch disks including a plurality of bolt means substantially uniformly distributed over the circumference of said driving clutch part for axially guiding said intermediate plate, a plurality of bores provided in said clutch part for force-locking retaining said bolts therein, each of said bolts extends through a corresponding bore provided in said intermediate plate, each of said bores being dimensioned to permit relatively large play between said bolts and said intermediate plate, a pair of abutment means disposed on each of said bolts for limiting the displacement of said intermediate plate spaced at a distance which at least approximates the play in the clutch between engagement and disengagement thereof, at least one of said pair of abutment means includes an abutment disk mounted and secured on each of said bolts, the other of said abutment means includes an abutment disk secured on each of said bolts, each of said abutment means being disposed on a respective side of said intermediate plate, means for force-lockingly retaining each of said bolts in its corresponding bore in said driving clutch part, a clamping sleeve arranged on each of said bolts between one of said abutment means and said driving clutch part, said clamping sleeve forcelockingly abutting the inner circumference of a respective bore in said driving clutch part, a spacer means disposed between said abutment means for maintaining a fixed distance therebetween, a clutch adjusting mechanism according to claim 23, said spacer means includes a spacer sleeve disposed between said abutment means whereby said force locking retention of said bolt means is overcome only by the actuating force of the clutch thereby readjusting said intermediate plate to correspond to the wear of said clutch disks.
