ABSTRACT:
This invention relates to grounding the mechanical loads of an electrically variable transmission with a park pawl system located in the end cover portion of the transmission housing. The end cover portion is configured to cover the park pawl system and engagement gear. A support hub is interfittable with the end cover portion of the transmission and sufficiently secured thereto so as to ground the park pawl loads. The hub also functions to guide oil to the cavity of a piston-clutch assembly. A method of securing a hub to an electrically variable transmission housing is also provided.
