ABSTRACT:
A friction clutch wherein several changeover levers which are made of sheet metal are interposed between the housing on the one hand and the two pressure plates on the other hand. Each changeover lever has two arms with convex surfaces which can roll along flat surfaces of the respective pressure plates and a median portion which cooperates with a fulcrum on the housing. When one of the pressure plates is moved away from the associated friction disc, the changeover levers roll along the associated fulcra and cause the other pressure plate to move away from the respective friction disc. If the clutch is a dependent-operated friction clutch, the fulcra and the median portions of the respective changeover levers define adjustable clearances in engaged condition of the clutch.
