20100276243 | HYDROKINETIC COUPLING DEVICE COMPRISING A LOCK-UP CLUTCH EQUIPPED WITH ELASTIC MEANS OF CIRCUMERENTIAL PRELOAD - A hydrokinetic coupling device includes a lock-up clutch having at least one friction disc mounted such that it can slide axially with respect to a first rotary shaft, at least one first backing disc rotating as one with a secondary rotary shaft and a support ring to support the backing disc. The support ring has at least one axial groove circumferentially delineated by an upstream face and by a downstream face. A radial guide tooth of each backing disc is housed such that it can slide axially in the groove. Elastic preload elements are provided which are able to exert a preload torque to clamp the guide tooth of each braking disc circumferentially against one of either the upstream or downstream faces of the guide groove. | 11-04-2010 |
20130220758 | HYDROKINETIC COUPLING DEVICE COMPRISING LOCK-UP CLUTCH EQUIPPED WITH ELASTIC MEANS OF CIRCUMFERENTIAL PRELOAD - A hydrokinetic coupling device includes a lock-up clutch having at least one friction disc mounted such that it can slide axially with respect to a first rotary shaft, at least one first backing disc rotating as one with a secondary rotary shaft and a support ring to support the backing disc.

20150308539 | DRIVEN PLATE WITH INTERMEDIATE PLATE CENTERING GUIDE - A turbine damper assembly, for a torque converter, includes a driven plate and an intermediate plate. The driven plate engages and drives the intermediate plate through elastic drive elements. The driven plate includes an axially extended, circumferentially oriented, driven plate flange that both centers the intermediate plate with respect to the drive plate and also assists in containing the elastic drive elements in circumferential curved cavities during and after assembly of the turbine damper assembly. | 10-29-2015 |
20150308554 | HYDROKINETIC TORQUE COUPLING DEVICE WITH CENTERED LOCK-UP CLUTCH FRICTION DISC, AND METHOD FOR ASSEMBLING THE SAME - A hydrokinetic torque coupling device comprises a turbine, a driven plate non-rotatably attached to the turbine, circumferentially oriented torque transmitting elastic elements, and a friction disc including peripheral, axially extending driving tabs. The driven plate includes circumferentially oriented centering slots such that the axially extending driving tabs of the friction disc protrude into the centering slots and engage the elastic elements. A method for assembling a hydrokinetic torque converter involves providing a driven plate including circumferentially oriented centering slots, elastic elements and a friction disc including peripheral axially extending driving tabs, mounting the friction disc and the elastic elements to the driven plate so that the driving tabs of the friction disc and the driven plate engage the elastic elements, and centering the friction disc with respect to the driven plate by protruding the driving tabs into the centering slots of the driven plate. | 10-29-2015 |
20150337933 | STATOR ASSEMBLY OF HYDROKINETIC TORQUE CONVERTER WITH PRESS CRIMPED RETAINER PLATES AND METHOD FOR MAKING THE SAME - A stator assembly of a hydrokinetic torque converter includes a stator rotatable about an axis and having a hub bore coaxial to the axis, the stator having a crimped portion, a one-way clutch mounted to the stator in the hub bore coaxially to the axis, and a retainer plate fixedly secured to the stator in hub bore by the crimped portion. A method for making a stator assembly of a hydrokinetic torque converter involves providing a stator having an axis and a hub bore that is coaxial with the axis, the hub bore containing a one-way clutch and an annular retainer plate, and crimping a portion of the stator to fixedly secure the one-way clutch and the annular retainer plate in the hub bore. | 11-26-2015 |
20150362041 | TORSIONAL VIBRATION DAMPER FOR HYDROKINETIC TORQUE COUPLING DEVICE - A torsional vibration damper of a hydrokinetic torque coupling device, comprises a driven plate rotatable about a rotation axis, an intermediate plate rotatably mounted about the driven plate coaxially with the rotation axis, a back plate rotatably mounted about the intermediate plate coaxially with the rotation axis, a plurality of circumferentially acting elastic members interposed between the driven plate and the intermediate plate, and a damper retainer plate non-moveably secured to the back plate coaxially with the rotation axis. The damper retainer plate is operatively connected to the elastic members. The driven plate, the intermediate plate and the back plate are aligned with each other along a radial axis perpendicular to said rotation axis. | 12-17-2015 |
