Abstract

675,249. Friction clutches. SOC. ANON. A. CITROEN. July 10, 1950 [July 18, 1949], No. 17236/50. Class 80 (ii). [Also in Group XXXIV] A non-warp disc for an electromagnetic clutch or brake comprises concentric friction rings 3 of magnetic metal attached to the radial arms 2 of non-magnetic spider 1 by stirrups 4 which can slide on the arms to accommodate thermal expansion of the rings. Both the driving and driven discs 1, 5 are so formed, and cooperate. with a stationary winding 8.
