Abstract

Amortisseur de torsion pour un groupe motopropulseur de véhicule, comprenant : ○ deux rondelles latérales (5), aptes à être entrainées en rotation autour d'un axe de rotation (X) ○ un disque central (7) se développant dans un plan parallèle aux rondelles latérales, entre les deux rondelles latérales et coaxialement auxdites rondelles latérales, ○ des organes élastiques (9) pour transmettre le couple entre le disque central et les rondelles latérales (5) et autorisant, lorsqu'ils se déforment, une rotation relative entre d'une part les rondelles latérales (5) et d'autre part le disque central (7) autour de l'axe de rotation (X), dans lequel les deux rondelles latérales (5) sont reliées l'une à l'autre par une entretoise (6, 106) dotée d'un corps d'entretoise (61, 161), la dimension tangentielle (d1) du corps d'entretoise (61, 161) étant inférieure à sa dimension radiale (d2).Torsional damper for a vehicle powertrain, comprising: ○ two lateral washers (5), capable of being rotated around an axis of rotation (X) ○ a central disc (7) developing in a plane parallel to the side washers, between the two side washers and coaxially with said side washers, ○ elastic members (9) for transmitting the torque between the central disc and the side washers (5) and allowing, when they deform, a relative rotation between d 'on the one hand the lateral washers (5) and on the other hand the central disc (7) around the axis of rotation (X), in which the two lateral washers (5) are connected to each other by a spacer (6, 106) provided with a spacer body (61, 161), the tangential dimension (d1) of the spacer body (61, 161) being less than its radial dimension (d2).
