Abstract
A clutch which reacts to torque overload has a ribbed disc which is produced by plastics injection moulding and which is, along its inner or outer periphery, encapsulated in encircling fashion and on both axial side surfaces by an encompassing ring. Said encompassing ring, owing to shrinkage as a result of cooling, enters into static friction engagement with the ribbed disc, and furthermore engages, by means of bevelled flanks, with ribs running radially on at least one of the side surfaces of the ribbed disc.

Clutch which reacts to torque overload, comprising:
- a ribbed disc which is produced by plastics injection moulding;
- and
- a plastic ring which encapsulates the ribbed disc in encircling fashion along an inner or outer periphery of the ribbed disc and on both axial side surfaces of the ribbed disc, wherein
- the plastic ring is in static friction engagement with said ribbed disc along the inner or outer periphery of the ribbed disc and furthermore engages, by means of bevelled flanks, with spoke-like ribs running radially on at least one of the side surfaces of the ribbed disc configured to effect a positive locking in a circumferential direction between the ribbed disc and the plastic ring.
