A fixed drive end housing includes an input ring gear and houses a noise reducing radially floating input carrier and a plurality of input planet gears rotatably mounted in the input carrier. The input sun gear is driven by an electric motor and drives the plurality of input planet gears which mesh with the input ring gear causing rotation of the input carrier about its true center. The input carrier is partially nested within the spindle-carrier and the motor is partially nested within the fixed drive end housing. | 06-02-2011 |
20120220411 | DUAL-DRIVE ELECTRIC MACHINE HAVING CONTROLLABLE PLANETARY GEAR SET (2) - The present invention relates to a clutch device structured by a dual-drive electric machine being combined with an planetary gear set (DG | 08-30-2012 |
20130065723 | Regulating the work output speed of an infinitely variable transmission using the rotational resistance created by a high-voltage alternator/generator mechanically connected to a secondary output shaft or gear from the IVT to restrain its rotation - This present invention uses the rotational resistance created by a high-voltage alternator/generator to regulate the speed of the primary work output shaft in an Infinitely Variable Transmission. This will be accomplished by mechanically and rotationally attaching the high-voltage alternator/generator to a secondary output shaft or gear in the IVT. Sending a signal to the high-voltage alternator/generator to create electricity will create rotational resistance against the secondary output shaft or gear, slowing the rotation of the secondary output shaft or gear and causing the primary work output shaft to speed up. The greater the electrical load that is applied to the high-voltage alternator/generator, the faster the primary work output shaft will turn. The lesser the electrical load, the slower the primary work output shaft will turn. | 03-14-2013 |
