Abstract
An electro-mechanical interface incorporated in a series hybrid auxiliary power unit. According to the present invention the electro-mechanical interface employs a first tier of geared output shafts rotatably supported within a frame and meshingly engaged in a daisy-chain configuration having first and second ends. One end of the first tier of geared output shafts in the daisy-chain configuration meshingly engages a first, geared transfer shaft. The first, geared transfer shaft selectively connects to an internal combustion engine through a selectively disengageable clutch. The other end of the aforesaid first tier of geared output shafts in the daisy-chain configuration meshingly engages a second geared transfer shaft that is continuously connected to a motor/generator. The geared output shafts in the aforesaid daisy-chain configuration are available to drive auxiliary loads. A second tier of geared output shafts are also rotatably supported within the frame. The geared output shafts in the second tier meshingly engage, also in a daisy-chain configuration having first and second ends. One end of the daisy-chain defined by the second tier of geared output shafts meshingly engages a geared linking shaft, and the geared linking shaft selectively connects to a geared transfer shaft associated with the first tier of geared output shafts. The geared output shafts in the second tier are also available to drive auxiliary loads.
