ABSTRACT:
A clutch friction disc or plate wherein a circular flange carries a set of equidistant blades each extending radially outwardly beyond its periphery and each having a pair of overlapping, elastic plates whose inner end portions are riveted to the flange. A friction lining is connected with the outer side of each plate by two rivets whose heads extend into complementary circular openings provided in the other plate of the respective pair. At least one opening of each plate communicates with at least one slot end of which communicates with the respective opening and the other end of which is closed, open by extending to the marginal portion of the respective plate, or communicates with the other opening in the respective plate. The slots reduce the likelihood of distortion of plates as a result of development of unequal stresses owing to unequal heating of all regions of the plates when the disc is engaged between a pair of torque-transmitting or torque-receiving elements of the clutch.
