Title (EN) BALANCING BODY AND BALANCING SYSTEM FOR BALANCING AN INTERNAL COMBUSTION ENGINE
(FR) ORGANE D'ÉQUILIBRAGE ET SYSTÈME D'ÉQUILIBRAGE POUR ÉQUILIBRER UN MOTEUR À COMBUSTION INTERNE
Abstract:
(EN) The invention relates to a balancing system for balancing an internal combustion engine (10), consisting of two balancing parts (24A, 24B) that are rotatably guided about two coplanar balancing axes (102A, 102B). Each balancing part (24A) comprises a body (25A) provided with at least one bearing (62, 64) for rotatably guiding the body (25A) and at least one first balancing mass (26A) that has a value M 1 and a centre of gravity located at a non-null distance E 1 from the balancing axis (102A), and is constrained to rotate with the body (25A) about the balancing axis (102A) and guided in relation to the body (25A) in such a way that the distance D 1 between the centre of gravity of the first balancing mass (26A) and a reference plane (C) containing the centre of gravity of the body (25A) is variable.
(FR) Un système d'équilibrage pour équilibrer un moteur à combustion interne (10) est formé de deux organes d'équilibrages (24A, 24B) guidés en rotation autour de deux axes d'équilibrage coplanaires (102A, 102B). Chaque organe d'équilibrage (24A) comporte un corps (25A) pourvu d'un ou plusieurs paliers (62, 64) de guidage en rotation du corps (25A), et au moins une première masse d'équilibrage (26A) ayant une valeur M1 et un centre de gravité situé à une distance non nulle E1 de l'axe d'équilibrage (102A), fixe en rotation par rapport au corps (25A) autour de l'axe d'équilibrage (102A) et guidée par rapport au corps (25A) de manière à ce que la distance D1 du centre de gravité de la première masse d'équilibrage (26A) à un plan de référence (C) contenant le centre de gravité du corps (25 A) soit variable.
