Overload clutch for e-motor rotor

A method of forming an overload clutch for protecting a hybrid drive arrangement that includes a housing, a stator mounted to the housing, and a rotor connected to an input shaft that is adapted to be connected to a transmission, with the rotor being rotatably mounted within the stator, the method comprising:

• providing the rotor with a rotor support connected to the input shaft, the rotor support including an axially extending mounting flange with a stop located at one axial end region of the mounting flange, a rotor stack located on the mounting flange, first and second rotor rings located on respective first and second axial sides of the rotor stack;
• pressing a diaphragm spring on the mounting flange on an opposite axial end region from the stop, clamping the second rotor ring, the rotor stack, and the first rotor ring against the stop in order to rotationally fix the rotor stack to the mounting flange;
• and
• providing a drive plate assembly configured to be connected to a crankshaft of an internal combustion engine, the drive plate assembly including an output flange, and one of:
• (a) frictionally engaging the output flange to at least one of the diaphragm spring or the second rotor ring such that application of a torque spike causes the output flange to rotate relative to the at least one of the diaphragm spring or the second rotor ring, or
• (b) rotationally fixing the output flange to the diaphragm spring such that application of a torque spike causes the diaphragm spring to rotate relative to the mounting flange.
