Abstract:
A planar one-way clutch comprising:a first plate; a second plate in close juxtaposed relationship with the first plate, each plate being rotatable about a common axis, one of the first and second plates being a driving plate and the other of the first and second plates being a driven plate, each plate having a coupling face and surfaces defining at least one recess in each of the respective coupling faces the recess in the first plate having a strut receiving portion and a spring receiving portion, the spring receiving portion including opposed circumferential surfaces; at least one torque-transmitting strut received within the strut receiving portion of the recess of the first plate, the strut being pivotable between a first position and a second position, the strut having an end surface which is spaced from the recess in the second plate when the strut is in the first position, the end surface of the strut disposed within the recess in the second plate when the strut is in the second position; and at least one spring received within the spring receiving portion of the recess of the first plate, the spring having a base and an arm, the arm extends from the base and has a strut engaging portion which engages the strut and applies a controlled spring force on the strut to urge the strut toward the second position, the base defining at least two diametrically-opposed surfaces that are in close-spaced opposition with the circumferential surfaces of the first plate to prevent at least circumferential movement of the spring relative to the spring receiving portion of the recess of the first plate.
