Abstract:
1. An automotive transmission comprising: an input member; an output member; a plurality of planetary gear sets, each planetary gear set of the plurality of planetary gear sets having a plurality of rotatable members; a plurality of torque transmitting mechanisms each selectively engageable to interconnect at least one of the rotatable members of the plurality of rotatable members with one of a stationary member and at least one other of the rotatable members of the plurality of rotatable members, at least one of the torque transmitting mechanisms of the plurality of torque transmitting mechanisms being an electromechanical rotating clutch assembly comprising: a rotor coupled to one of a first rotatable member of the plurality of rotatable members and a stationary member; an armature coupled to one of a stationary member and another rotatable member of the plurality of rotatable members; and an electromagnetic coil, the electromagnetic coil being operable to selectively engage the rotor with the armature, wherein the plurality of torque transmitting mechanisms are selectively enqaqeable to establish a plurality of forward speed ratios and at least one reverse speed ratio between the input member and the output member.
