HYBRID DRIVE FLEXIBLE DRIVE COUPLING AND SHIPPABLE ASSEMBLY OF A HYBRID DRIVE WITH FLEXIBLE DRIVE COUPLING

A drive arrangement for an engine, the drive arrangement, which can be a P1 hybrid or hybrid series generator arrangement, includes a drive housing and an Emotor including a stator and a rotor, with the stator being supported in the housing. A flex-plate coupling having at least two flex plates, with fasteners connecting end regions of the at least two flex plates, is provided, and a first flex-plate has openings that are adapted to receive fasteners for direct connection to an end of the engine crankshaft. A last of the flex plates is connected to the rotor. The rotor has a rotor support with a pilot at a first end that is received in a pilot opening in the end of the crankshaft and a second end with a support flange. A hub support is connected to the drive housing and rotatably supports the support flange of the rotor support.
