  • One-way clutch
    Patent number: 6907971
    Abstract: A one-way clutch assembly comprises a clutch casing including a first plate coupled to a second plate, such as clutch inner and clutch outer plates. The first and second plates have a common central axis, the first and second plates are spaced apart along the common axis to define an interior. The assembly also includes a ratchet plate disposed in the interior between the first and second plates, the ratchet plate has the same common axis and is displaceable along the axis within the interior. A first torque transfer mechanism, such as a set of mating splines is used to rotationally couple the ratchet plate to the first plate. A second one-way torque transfer mechanism is used for releasably coupling the ratchet plate to the second plate, the second transfer mechanism including a set of fixed flat and angled portions formed on a ratchet plate surface opposite the second plate and a complimentary set of fixed flat and angled portions formed on a second plate surface opposite the ratchet surface.
