INTEGRATED ELECTROMAGNETIC CLUTCH AND EDDY-CURRENT COUPLING

摘要

A system (100) for transmission of power includes a clutch (110) having a driven clutch member (6) and a driving clutch member (7). The driven and driving clutch members (6, 7) are operatively connected to one another for common rotation in a first position with the clutch members (6, 7) engaged to one another and for rotation relative to one another in a second position with the clutch members (6, 7) disengaged from one another. An eddy-current coupling (12) is operatively connected to selectively move at least one of the clutch members (6, 7) to engage and disengage the clutch members (6, 7) between the first and second positions. The eddy-current coupling is also operatively connected to provide electromagnetic eddy-current coupling between the clutch members (6, 7) with the clutch members (6, 7) in the second position disengaged from one another to drive the driven clutch member (6) at a rate different from that of the driving clutch member (7).
