Abstract
A hybrid drive assembly having an e-motor with a housing fixed stator and a rotor that connects to a transmission. The e-motor rotor includes a rotor support having a mounting flange with a stop at one end. A diaphragm spring clamps a second rotor ring, a rotor stack, and a first rotor ring against the stop to rotationally fix the rotor stack to the mounting flange. A drive plate assembly for connection to a crankshaft includes an output flange that is: (a) frictionally engaged to the diaphragm spring and/or the second rotor ring such that upon application of a torque spike the output flange rotates relative to the diaphragm spring and/or the second rotor ring, or (b) rotationally fixed to the diaphragm spring such that upon application of a torque spike the diaphragm spring rotates relative to the mounting flange, forming in each case an overload clutch.
