The first part of the housing comprises an inner axial cylindrical portion for retaining radially said outer ring and the second part of the housing comprises an outer axial cylindrical portion surrounding said inner axial cylindrical portion. | 11-20-2014 |
20140346005 | BALL AND RAMP DEVICE FOR A TOROIDAL VARIATOR - The ball and ramp device for a toroidal variator includes a first disc and a second disc and a plurality of rolling elements disposed between ramps provided on the discs and extending along the circumferential direction. One of the discs provides a plate having the ramps, a ring delimiting an outer toroidal raceway and an intermediate supporting part axially interposed between said ring and the plate. | 11-27-2014 |
20150013848 | Method for Manufacturing A Torque Transmission Mechanism - A method for manufacturing a torque transmission mechanism between a starter motor and a crankshaft of an internal combustion engine, comprising a one-way clutch including an outer ring fast in rotation with the crankshaft via a front plate. This method comprises the following steps: a) forging the outer ring out of carburizing steel, b) carburizing the outer ring, c) tempering the outer ring, d) grinding an inner surface of the outer ring, e) manufacturing the front plate out of standard low equivalent carbon content steel, and f) assembling the front plate and the outer ring. | 01-15-2015 |
20150014119 | Torque Transmission Mechanism - A torque transmission mechanism for an internal combustion engine, adapted to transmit a starting torque from a starter motor to a crankshaft of the internal combustion engine. The torque transmission mechanism includes a ring gear that transmits the starting torque, a one-way clutch disposed between the ring gear and the crankshaft, a bearing including a first ring coupled in rotation with the gear ring and a second ring coupled in rotation with the crankshaft and a front plate for coupling in rotation the crankshaft with the one-way clutch. The front plate is coupled in rotation with the crankshaft via the second ring of the bearing, by welding along a direction parallel to a central axis of the second ring of the bearing. | 01-15-2015 |
