Abstract
This invention relates to freewheels comprising a plurality of rollers interposed between inner and outer races formed on driving and driven members respectively, one of said races having a plurality of wedge-shaped portions equal in number to the number of rollers. The invention is particularly concerned with cageless freewheels of this construction, and discloses a means for moving said rollers between a first position in which the rollers assume an engaged position to transmit rotation to the driven member, and a second position in which the rollers are retained in a disengaged position. This is accomplished by at least one actuating lever interposed in the rollers, and being capable of limited circumferential movement between said first and second positions. In one embodiment the actuating lever has parallel side portions for engagement with adjacent rollers, and in a second embodiment the actuating lever includes a circular section spindle portion rotatably mounted in an axial bore in one of the rollers.
