Patent Images
1. A turboalternator for a hybrid motor vehicle comprising:
- a low speed portion to generate electrical power; and
a high speed portion to generate electrical power, said high speed portion being generally parallel to said low speed portion and being mechanically independent from the low speed portion;
each of said low speed portion and said high speed portion comprising;
a compressor;
a turbine;
an alternator disposed between said compressor and said turbine; and
a common shaft interconnecting said compressor, said alternator and said turbine;
wherein said shaft is supported by hydrodynamic bearings.
