  • Publication number: 20160258494
    Abstract: A one-way clutch configured for decoupling an alternator pulley from an alternator hub in a motor vehicle drive system is provided. The one-way clutch includes a ramp plate for non-rotatable connection with an inner circumferential surface of the pulley and rollers in axial engagement with the ramp plate. The rollers are movable along ramped surfaces of the ramp plate between a first position and a second position. The one-way clutch also includes an elastic assembly forcing the ramp plate and rollers into the axial engagement. The elastic assembly axially forces the rollers to transfer torque from the pulley into the hub when the rollers are in the first position. The hub is rotationally decoupled from the pulley when the rollers are in the second position.

  • Patent number: 9188167
    Abstract: The present invention broadly comprises a spring-retaining clutch housing including a housing wall and at least one opening in the wall. The opening is arranged to accept at least a portion of a lever spring for a clutch assembly. The lever spring includes at least one protrusion, extending from an outer circumference of the spring, with top and bottom sides. The opening defines edges in the housing wall axially displaced one to the other. The edges are arranged to be contacted by the top and bottom sides, respectively. In some aspects, contact with edges is arranged to provide forces in two, opposite axial directions. In some aspects, the housing is arranged for installation in a clutch assembly with a bearing and a clutch and the forces are for a pre-load force for the assembly bearing or with respect to an axial force generated during operation of the clutch.
