Patent ID: 8434439

Claim:
A clutch or brake ( 11 ) with an electrically actuated switching coil ( 12 ) and an armature ( 13 ) that is axially movable toward the switching coil ( 12 ) to form a either a frictional or an interlocked connection with the switching coil ( 12 ) and being rotatable relative to the switching coil ( 12 ), in a transmission ( 1 ) comprising a superposition transmission ( 1 ) with a drive input element ( 4 ) that is driven by a crankshaft of an internal combustion engine, a drive output element ( 3 ) that drives a camshaft of the internal combustion engine, and a control element by which relative rotation between the drive input element ( 4 ) and the drive output element ( 3 ) is produced by applying a braking torque, the armature ( 13 ) being arranged in a rotationally fixed and displaceable manner, centered either on or at a transmission component ( 6 ), and the switching coil ( 12 ) being attached in a rotationally fixed manner and centered coaxially with the armature ( 13 ) by a membrane spring ( 22 ) on a further transmission component ( 10 ), relative to which either the armature ( 13 ) being braked or the armature ( 13 ) being coupled.
