Abstract

Un système d'équilibrage (22) pour équilibrer un moteur à combustion interne (10) comporte un premier organe tournant d'équilibrage de basculement (24A) tournant autour d'un premier axe d'équilibrage de basculement (102A) non parallèle à l'axe de référence (100), et ayant un premier balourd dynamique par rapport au premier axe d'équilibrage de basculement (102A), un deuxième organe tournant d'équilibrage de basculement (24B) tournant autour d'un deuxième axe d'équilibrage de basculement (102B) non parallèle à l'axe de référence (100), et ayant un deuxième balourd dynamique par rapport au deuxième axe d'équilibrage de basculement (102B), et un mécanisme d'entraînement synchronisé (28) pour entraîner le premier organe d'équilibrage de basculement (24A) le deuxième organe d'équilibrage de basculement (24B) en rotation à des vitesses égales et en sens opposé, de telle sorte que le premier organe d'équilibrage de basculement (24A) et le deuxième organe d'équilibrage de basculement (24B) génèrent ensemble sur le bloc moteur (12) un couple de compensation de basculement autour de l'axe géométrique de référence (100).A balancing system (22) for balancing an internal combustion engine (10) comprises a first rotary tilt balancing member (24A) rotating about a first tilt balancing axis (102A) not parallel to the 'reference axis (100), and having a first dynamic unbalance with respect to the first tilt balancing axis (102A), a second tilting swing balancing member (24B) rotating around a second balancing axis tilt (102B) not parallel to the reference axis (100), and having a second dynamic unbalance with respect to the second tilt balancing axis (102B), and a synchronized drive mechanism (28) for driving the first tilt balancing member (24A) the second tilt balancing member (24B) rotating at equal speeds and in opposite directions, so that the first tilt balancing member (24A) and the second e organ tilt balancing (24B) together generate on the engine block (12) a tilt compensation torque around the geometric reference axis (100).
