Abstract:
Compression spring members, particularly for friction clutch assemblies. The compression spring members include a plurality of deformable members and where the amount of force necessary to compress the spring member lessens over displacement once a peak amount of force is reached. The compression spring members can comprise a plurality of buckling beam spring members, a plurality of connecting members, or the like. One or more ring members can be provided for attachment to the connecting members. The friction clutch assembly is preferably used for a hybrid coolant pump with two modes of operation, an electric motor operation and a mechanical pulley-driven operation.
