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. The assembly also has a biasing mechanism for monitoring the relative axial displacement between the ratchet plate with respect to the second plate, the biasing mechanism for providing an axial force for engaging the ratchet surface with the second plate surface. Accordingly, engagement of the complimentary flat and angled portions effects the one-way torque transfer between the ratchet plate and the second plate. The biasing mechanism can include mechanical and hydraulic actuation.
