Claims7
A selectively configurable hybrid electro-mechanical vehicular transmission comprising:
- a transmission main housing operable to contain at least one motor/generator assembly;
- an output shaft;
- an end housing configured for four-wheel drive transfer case attachment, said end housing being attachable to said main housing;
- an adapter housing attachable to said end housing and operable to configure said end housing to accommodate a two wheel drive vehicular configuration in lieu of said four-wheel drive transfer case attachment;
- said adapter housing having a bushing operable to pilot a driven shaft onto said output shaft;
- and
- said adapter housing having a seal in frictional communication with said driven shaft and operable to both prevent debris from entering said selectively configurable hybrid electro-mechanical vehicular transmission, and to prevent transmission fluid from exiting said selectively configurable hybrid electro-mechanical vehicular transmission.
