Abstract

L'invention concerne un amortisseur de torsion pour véhicule automobile, notamment pour une chaîne de transmission de véhicule automobile, comportant : - un premier élément (7) destiné à être monté sur un nez (8) d'un vilebrequin (1) accouplé à des pistons (2, 27), ledit premier élément (7) présentant un axe géométrique de basculement (13) autour duquel bascule le premier élément (7) lorsqu'il est monté sur le nez (8) du vilebrequin (1) ; - un deuxième élément (9) monté mobile en rotation par rapport au premier élément (7), - un organe d'amortissement à lames comportant deux surfaces de came et deux suiveurs de came (11) agencé entre le premier élément (7) et le deuxième élément, les suiveurs de came (11) définissant un axe géométrique d'appui des suiveurs de came (11) l'amortisseur étant agencé de sorte qu'aucun appui de suiveur de came sur sa surface de came ne se situe, en projection dans un plan perpendiculaire à l'axe de rotation (X), dans un secteur angulaire critique, ledit secteur angulaire critique (Cr) étant supérieur ou égal à 40 degrés et s'étendant de part et d'autre de la perpendiculaire (P) à l'axe géométrique de basculement (13).The invention relates to a torsion damper for a motor vehicle, especially for a motor vehicle chain, comprising: a first element (7) intended to be mounted on a nose (8) of a crankshaft (1) coupled to pistons (2, 27), said first element (7) having a tilting geometric axis (13) around which the first element (7) tilts when it is mounted on the nose (8) of the crankshaft (1); a second element (9) rotatably mounted relative to the first element (7); a blade damping element comprising two cam surfaces and two cam followers (11) arranged between the first element (7) and the second element, the cam followers (11) defining a geometric axis of support of the cam followers (11) the damper being arranged so that no cam follower support on its cam surface is located, in projection in a plane perpendicular to the axis of rotation (X), in a critical angular sector, said critical angular sector (Cr) being greater than or equal to 40 degrees and extending on either side of the perpendicular (P) ) to the geometric tilt axis (13).
