Abstract
A clutch includes inner and outer races, each with pluralities of teeth. A pawl is supported on the inner race and a shift ring disposed outward of the pawl defines pawl engagement surfaces on an inner perimeter. Pins engage cam surfaces formed in the ring and outer race. When the inner race rotates faster than the outer race, the pawl engages the ring causing relative movement between the ring and outer race that moves the pins radially inward along the cam surfaces to locate the pins between corresponding teeth on the races and rotatably couple the races. When the outer race rotates faster than the inner race, the ring moves relative to the outer race and the pins move radially outward along the cam surfaces away from the corresponding teeth to uncouple the races, disengage the ring from the pawl and allow the outer race to overrun the inner race.
