Ratchet one-way clutch with stator

Abstract

A ratchet-type one-way clutch mechanism. The mechanism has an inner race member with a plurality of notches, an outer stator member with a plurality of pockets, a plurality of pawl members positioned in the pockets for engagement with the notches, and spring biasing members for biasing the pawl members toward engagement. The stator member is made from a non-ferrous material, such as aluminum or a plastic material. The pawl members have pivot ridges which mate with peaks or recesses in the pockets in the outer member to precisely position the pawls in the pockets. The centers of mass of the pawl members are selectively positioned such that the pawl members will have a tendency to become engaged or disengaged with the notches in the inner member. The spring biasing members can be Z-shaped springs, garter springs, or the like.
