20150291256 | HUBS INCORPORATING A VARIABLE RATIO TRANSMISSION SYSTEM - A hub comprises a cylindrical, hollow hub member which is mounted to rotate about its axis and accommodated in whose interior is a continuously variable ratio transmission system having an input, which is mounted to rotate about the axis, and an output mounted to rotate with the hub member. The transmission system comprises a single epicyclic gearset including a sun gear in mesh with a plurality of planet gears mounted to rotate about respective planet shafts carried by a common carrier, which is mounted to rotate with the input about the axis. The planet gears are in mesh with an annulus gear, which is connected to rotate with the rotors of first and second electric motor/generators, respectively. The electrical connections of the stators of the two motor/generators are connected by a controller arranged to control the transmission of power from one motor/generator to the other. The hub further includes a one-way clutch, which includes a drive member, which is constituted by the common carrier and a driven member, which is connected to rotate with the hub member. The one-way clutch is arranged to connect the hub member to rotate with the carrier as soon as the carrier rotates faster than the hub member. | 10-15-2015 |
20110270508 | METHOD OF AND APPARATUS FOR OPERATING A SUPERCHARGER - A method of and apparatus for operating a supercharger for an automotive engine is disclosed. The supercharger has: an input shaft for coupling to an engine crankshaft, and coupled to the rotor of a first electrical machine and a first component of an epicyclic gear train; and an output shaft connected to a compressor and a second component of the epicyclic gear train; wherein the third component of the epicyclic gear train is connected to the rotor of a second electrical machine. The first electrical machine is selectively operable to supply electrical energy to the second electrical machine. The method includes the steps of: (a) calculating a required speed of the second electrical machine that would give rise to a required pressure at an outlet of the compressor; and (b) setting the speed of the second electrical machine to the calculated required speed. | 11-03-2011 |
