20140375159 | ROLLER DEVICE FOR A TRACTION MECHANISM DRIVE OF A MOTOR VEHICLE - A roller device for a traction mechanism drive, with a roller element for introducing a torque provided via the traction mechanism and a driven shaft for driving an auxiliary unit of a motor vehicle. The roller device further has a magnetic coupling for torque transfer between the roller element and the driven shaft. The magnetic coupling has a primary-side unit connected to the roller element having a primary magnetic element and a secondary-side unit connected to the driven shaft with a secondary-side magnetic element. The magnetic elements are permanent and/or electromagnetic elements and the torque transfer is realized by magnetic fields of the primary and secondary-side magnetic elements. At least one magnetic element of the two units for changing the magnetic field overlap of the magnetic fields of the primary and secondary-side magnetic elements is arranged movably within its unit by the centrifugal forces occurring during operation. | 12-25-2014 |
20110127869 | MAGNETIC GEAR - Embodiments of the present invention relate to magnetic gears comprising first and second moveable members arranged to interact in a magnetically geared manner via a first electrical winding arrangement arranged to generate, at least in part, a first magnetic flux having a first number of pole-pairs, and one or more pole-pieces arranged to modulate the first magnetic flux to interact with a second magnetic flux having a second number of pole-pairs, wherein the first number of pole-pairs is less than the second number of pole-pairs. | 06-02-2011 |
20110234034 | MAGNETIC GEAR ARRANGEMENT - A magnetic gear arrangement comprises: (i) a first gear member for generating a first magnetic field, (ii) a second gear member for generating a second magnetic field, and (iii) a coupling device which provides arrangements of interpoles between the first gear member and the second gear member. The interpoles couple the first and second magnetic fields such that different arrangements of interpoles produce different gear ratios between the first and second gear members. The coupling device comprises a plurality of ferromagnetic pole elements which at leastly partly form the interpoles. Each pole element has a Curie temperature whereby the pole element is active below its Curie temperature and inactive above its Curie temperature. The magnetic gear arrangement further comprises a temperature controller for controlling the temperature of at least some of the pole elements such that, under the control of the temperature controller, the temperatures of pole elements can cross their respective Curie temperatures and thereby change from active to inactive or the reverse. | 09-29-2011 |

20130099615 | MAGNETIC TORQUE SYSTEMS - A magnetic continuously variable-range transmission exemplifying a continuously variable magnetic torque transmission system using a magnetically patterned cone and magnetically engaged drive gears that are positionable parallel to the cone's surface using actuators. The actuators are responsive to a controller. By changing the position of the magnetic drive gears, the effective gear ratio changes smoothly between the maximum and minimum gear ratios for the particular embodiment. The magnetic drive gears are mechanically coupled to planetary gears that drive a sun gear which drives the output shaft. The cone may be patterned with magnets in such a way as to create a constant-torque transmission. The magnets in the pattern are placed, printed, or impressed, in a non-magnetic matrix. | 04-25-2013 |
