Title (EN) HEAT ENGINE COMPRISING BALANCE SHAFTS WHICH CAN BE LOCKED BY A PIN
(FR) MOTEUR THERMIQUE COMPORTANT DES ARBRES D'EQUILIBRAGE SUSCEPTIBLES D'ETRE IMMOBILISES PAR UNE EPINGLE
Abstract:
(EN) The invention relates to a heat engine (10) comprising at least one engine block which rotatably receives a crankshaft (12) and a cartridge (16) which is fixed to the engine block and which rotatably receives a pair of parallel balance shafts, namely a primary shaft (26) and a secondary shaft (28), which are rotated by the crankshaft (12). The invention also comprises a ring gear (34) which is rotationally connected to the crankshaft (12), permanently meshing with a first pinion (36) borne by one end (38) of the primary balance shaft (26). In addition, a second pinion (40), borne by the end (38) of the primary balance shaft (26), meshes with a pinion (42) borne by one end of the secondary balance shaft (28). The invention is characterised in that transverse holes (46, 48) extend through the ends (38, 44) of the primary (26) and secondary (28) balance shafts and are intended to be aligned with one another, before the cartridge (16) is mounted to the engine block, in order to receive a pin (50).
(FR) L'invention propose un moteur thermique (10), qui comporte au moins un bloc moteur recevant en rotation un vilebrequin (12) et une cassette (16) fixée au bloc moteur qui reçoit en rotation une paire d'arbres d'équilibrage parallèles primaire (26) et secondaire (28) qui sont entraînés en rotation par le vilebrequin (12), une couronne (34) solidaire en rotation du vilebrequin (12) engrenant en permanence avec un premier pignon (36) porté par une extrémité (38) de l'arbre (26) d'équilibrage primaire, et un second pignon (40) porté par l'extrémité (38) de l'arbre d'équilibrage primaire (26) engrenant avec un pignon (42) porté par une extrémité de l'arbre d'équilibrage secondaire (28), caractérisé en ce que les extrémités (38, 44) des arbres d'équilibrage primaire (26) et secondaire (28) sont traversées par des perçages transversaux (46, 48) qui sont destinés, préalablement au montage de la cassette (16) sur le bloc moteur, à être alignés l'un avec l'autre pour recevoir une épingle (50).
