ABSTRACT:
An electrical actuation system for a drive utilizing one or more disc stacks having annular discs alternately connected with two or more drive components. A disc stack is directly selectively clamped by an armature of an armature assembly being magnetically attracted to an electromagnetic coil of an electromagnetic coil assembly upon energization of an excitation current in the electromagnetic coil. The armature has a zero air gap with respect to the electromagnetic coil when the disc stack is clamped. A plurality of armature springs are carried with the armature assembly and are compressed when the armature assembly biases against the disc stack, thereby accommodating wear of the discs. Clamping of the disc stack results in the two drive components connected therewith being interconnected. Upon the excitation current being switched off, the disc stack is no longer clamped and the two drive components are now unconnected. The electrical actuation system may be used in a clutch, brake or any number of clutch and brake combinations.
