Abstract
The invention relates to a centrifugal clutch with coupling jaws and pressure spring. Usually tension springs are used for the type of couplings which have three jaws. Tension springs have a weak point in their attachment lugs that are in most cases exposed to harder stress than the rest of the spring body. Likewise, the lugs get often indication of fracture during the manufacture of owing to wear. The present proposal aims at getting a higher security against spring breaks by using pressure springs. It is characterized by hole spaces (18,19,29) in jaws (13) and spoke plates (14,15) and by supporting bridges (23) between the spoke plates.
