ABSTRACT:
A speed responsive centrifugal clutch having a one-way clutch function and suitable for use as a lock-up clutch of a torque converter is provided. The one-way clutch is provided not as a separate component but as structurally integrated in the clutch. The speed responsive centrifugal clutch includes a clutch plate fixedly mounted on a rotating shaft, a damper plate supported to be rotatable relative to the clutch plate and carrying damper elements, a reaction ring supported to be rotatable over a predetermined angle range relative to the damper plate, a plurality of shoe assemblies supported by the reaction ring to be displasable radially outwardly due to centrifugal forces, and a one-way clutch mechanism incorporated between the clutch plate and the damper plate. Because of the provision of such a one-way clutch mechanism in this particular manner, the overall size of the clutch can be minimized and transmission of rotating force can be carried out extremely smoothly.
