Abstract:
The present invention is a ratcheting one-way clutch for an automotive component such as, for example, a stator for a torque converter. A plurality of ramp plates is provided that are positioned on either side of the catch plate. Each ramp plate includes a series of locking fingers directed at an angle toward the catch plate in a plane that enables the fingers to engage with one of the at least one windows on the catch plate. Such an engagement prevents the catch plate from rotating in the engagement direction, while the angled orientation of the locking fingers allows the catch plate to rotate freely in the opposite (freewheeling) direction. Biasing elements are proved to axially bias the ramp plates toward the centrally positioned catch plate.
