|20120198962||Hybrid Vehicle Transmission - A transmission for a Series/Parallel Hybrid Vehicles (SPHV) enabling the vehicle to switch between series and parallel modes while the vehicle is in motion and while both the traction motor and the prime mover are operating at efficient levels is described herein. The traction motor and the prime mover are connected to an intermediate shaft via different ratio gear assemblies. A clutch is provided between the prime mover gear assembly and the intermediate shaft to allow the switch between the series mode and the parallel mode.||08-09-2012|
|20120117790||Insertion System and Method to Insert Insulators and Coils in the Slots of the Stator of an Electric Machine - The insertion of electrically insulating paper from a continuous roll into slots of a stator created by outwardly projecting teeth is described herein. The insertion of the insulating paper is done by the insertion of prewound coils in the stator slots. The electrically insulating paper is not cut prior to its insertion in the slots, thereby completely covering the outer surface of the stator. The insertion systems and methods described herein are also optionally concerned with the insertion of interphase insulation paper between the different coils inserted in the stator slots and with the insertion of slot closing wedges.||05-17-2012|
|20110278968||Multi-Path Liquid Cooling Arrangement for Electric Machines - A multi-path liquid cooling arrangement for electric machines comprising a heat storing element provided with channels having a generally C-shaped cross-section and cooling tubes so configured and sized as to be insertable in the channels is described herein. The cooling tubes, once inserted in the channels are deformed to conform thereto, whereby heat stored in the heat storing element is extracted by circulating cooling fluid inside the cooling tubes.||11-17-2011|
|20090221390||Hybrid Transmission for Hybrid Vehicles - A hybrid transmission described herein comprises a planetary gear arrangement and a clutch including two electromagnetic clutch portions used to interconnect an internal combustion engine, an electric traction motor, an electric motor/generator and driving wheels of a hybrid vehicle. The hybrid transmission described herein allows various modes of operation.||09-03-2009|
