Abstract

A single-action freewheel with an open diameter greater than 50 mm and with an inner and outer ring. The object is to provide an open central diameter of more than 500 mm while allowing high torques in a freewheel that can be made without consuming much material. The invention is charaterized by two or more rows (3 & 4) of shoes or jaws between the inner ring (1) and the outer ring (2) with normal clutching forces tht act more or less on one plane (13) or diameter, by one or more revolving webs (6) connected to the rings and extending between the rows, and by an activating mechanism (9) that approximately simultaneously tightens and loosens the shoes.
