AN ELECTRO-MECHANICAL CLUTCH APPARATUS

摘要

An electro-mechanical clutch apparatus includes a stationary member having a center portion extending along an axis A and a stationary coil assembly fixed about the center portion. A rotatable member extends along the axis A and includes an annular projection radially spaced from the coil assembly. A ratchet surface presents a plurality of teeth disposed in axially aligned and radially spaced relationship with the annular projection. The rotatable member includes a magnetic pole piece disposed in radially spaced and concentrically aligned relationship with said coil assembly. The rotatable member includes a locking member pivotably attached to the annular projection and pivotable between an engaged position in engagement with one of the teeth in response to the coil assembly being de-energized and a released position displaced from engagement with the teeth and attracted towards the magnetic pole piece in response to the coil assembly being energized.
