Abstract

In this speed limiter with cam wheel and pivot lever and pivot roller, a force limiter wheel with a plurality of dogs is provided at the pivot lever instead of a dog entering into the path of ratchet wheel teeth, wherein the force limiter wheel is braked by means of a slip clutch. If in the case of triggering the braking force in the limiter cable exceeds the force of the slip clutch the force limiter wheel rotates at the dog disposed in engagement with the ratchet wheel teeth, in which case the cable pulley rotates therewith and the stress in the limiter cable builds up and the succeeding dog enters into the path of the ratchet wheel teeth and blocks the cable pulley again. The parts participating in the triggering can thereby be protected from excessive action of force.
