Abstract

The invention relates to a freewheel system, in particular for permanently engaged starters, having an inner ring which is coupled to a crankshaft/primary mass and having an outer ring which is coupled to a toothed starter ring, wherein the toothed starter ring is mounted on an engine block/engine flange, and also having a clamping body freewheel in which clamping bodies are pivotably/rotatably held in a cage, which clamping bodies, in the decoupled state, are spaced apart from the inner ring and, upon starting, can be moved into a coupled state by means of a rotational movement of the cage, wherein means for a further freewheel are provided within the clamping body freewheel, which means, after the start, when the toothed starter ring/outer ring is turning back, assist the pivoting movement of the clamping bodies into the decoupled state and thereby assist the decoupling of the freewheel.
