Abstract: An electromagnetic clutch has a toothed driving clutch member and a toothed driven clutch member which are moved together upon energization of an electromagnet with their teeth in engagement. A spring disengages the teeth when the electromagnet is deenergized. The spring provides a relatively large spring force for initial breakaway to overcome residual magnetism and metal to metal contact of the teeth. After initial breakaway the spring provides only sufficient force to further separate the members. With this arrangement a small magnet may be used to engage the clutch because the large force of the spring must be overcome only during final engagement of the clutch.

The carrier has an inner radial flange forming an abutment for one of the friction foils of the first set, the second ribs being axially offset from the first ribs and extending beyond that flange in the form of peripherally separated prongs. The inner sleeve surface diverges outwardly from the region of the flange, with a slight draft as needed for casting; at its wider end the sleeve is fastened to a similarly produced first clutch housing accommodating a first piston normally held spaced apart from the first friction foils by a Belleville spring inserted between the sleeve and that clutch housing.
