Title (EN) DEVICE PROVIDING ROTATIONAL COUPLING BETWEEN AN ENGINE FLYWHEEL AND A CRANKSHAFT
(FR) DISPOSITIF D'ACCOUPLEMENT EN ROTATION ENTRE UN VOLANT MOTEUR ET UN VILEBREQUIN
Abstract: front page image
(EN)The invention relates to a coupling device for an engine flywheel (23) rotationally coupled to an internal combustion engine crankshaft (21), characterized in that it comprises a connecting piece (214) between the flywheel (23) and the end of said crankshaft (21) on the flywheel (23) side, the assembly of which comprises a smooth surface, between said connecting piece (214) and a crank web (211) of the crankshaft (21) situated at the end of said crankshaft (21) on the flywheel (23) side, able to accept a rolling bearing (216) with a one-piece mount, the surfaces for contact on said connecting piece (214) and on said end of said crankshaft (21) comprising raised patterns (215) positioned perpendicular to the axis of said crankshaft (21), said patterns (215) on each of said surfaces complementing one another so that the ones can drive the others through mutual collaboration.
(FR)L'invention concerne un dispositif d'accouplement d'un volant moteur (23) accouplé en rotation à un vilebrequin (21) de moteur à combustion interne, caractérisé en ce qu'ilcomporte une pièce de jonction (214) entre le volant moteur (23) et l'extrémité dudit vilebrequin (21) du côté du volant moteur (23), dont l'assemblage comporte une surface lisse, entre ladite pièce de jonction (214)et un bras (211) du vilebrequin (21) situé à l'extrémité dudit vilebrequin (21) du côté du volant moteur (23), apte à recevoir un roulement (216) à palier monobloc, les surfaces de contact sur ladite pièce de jonction (214) et ladite extrémité dudit vilebrequin (21) comportant des sculptures (215) en relief positionnées perpendiculairement à l'axe dudit vilebrequin (21), lesdites sculptures (215) sur chacune desdites surfaces étant complémentaires de manière à être aptes à s'entrainer mutuellement par coopération entre elles.
