Abstract

Réducteur (3) pour groupe motopropulseur de véhicule électrique ou hybride, comprenant : - au moins une roue (2) mobile en rotation autour d’un axe (X) et apte à transmettre le couple généré par un moteur électrique (101), cette roue comprenant une pluralité de dents (4) s’étendant chacune axialement le long de tout ou partie de la roue (2) en oblique par rapport à l’axe de rotation (X), et - un dispositif d’amortissement pendulaire (5) associé à cette roue (2), ayant un support (6) solidaire en rotation de la roue (2) et au moins un corps pendulaire (7) dont le déplacement par rapport au support (6) est guidé par au moins une piste de roulement, cette piste de roulement étant configurée pour guider le déplacement du corps pendulaire (7) par rapport au support (6) exclusivement selon une direction non perpendiculaire à l’axe de rotation (X) de la roue (2). Figure d’abrégé : Fig. 3Reducer (3) for the powertrain of an electric or hybrid vehicle, comprising: - at least one wheel (2) movable in rotation around an axis (X) and capable of transmitting the torque generated by an electric motor (101), this wheel comprising a plurality of teeth (4) each extending axially along all or part of the wheel (2) obliquely relative to the axis of rotation (X), and - a pendular damping device (5 ) associated with this wheel (2), having a support (6) integral in rotation with the wheel (2) and at least one pendular body (7) whose movement relative to the support (6) is guided by at least one track rolling, this rolling track being configured to guide the movement of the pendular body (7) relative to the support (6) exclusively in a direction not perpendicular to the axis of rotation (X) of the wheel (2).
