Title (EN) HEAT ENGINE COMPRISING A SYSTEM FOR VARYING THE COMPRESSION RATIO
(FR) MOTEUR THERMIQUE MUNI D'UN SYSTÈME DE VARIATION DU TAUX DE COMPRESSION
Abstract:
(EN) The invention relates to a heat engine comprising a system for varying the compression ratio of the engine, said compression ratio varying system comprising: at least one eccentric part (21) rotatably mounted on a crank pin, said eccentric part (21) comprising an eccentric outer face (25) that co-operates with one end of a rod, as well as at least one ring gear (28); and a device (31) for controlling the angular position of the eccentric part (21), comprising an actuating pinion (33) mounted on an actuating shaft (32), said control device (31) also comprising at least one stepped intermediate pinion (36) having at least first and second steps each formed by a pinion (37, 38), the pinion (37) of the first step meshing with the actuating pinion (33) and the pinion (38) of the second step meshing with the eccentric ring gear (28).
(FR) L'invention porte sur un moteur thermique comportant un système de variation d'un taux de compression dudit moteur, qui comprend - au moins une pièce excentrique (21 ) montée rotative sur un maneton de vilebrequin, ladite pièce excentrique (21 ) comportant une face externe (25) de forme excentrique destinée à coopérer avec une extrémité d'une bielle, ainsi qu'au moins une couronne dentée (28), - un dispositif de commande (31 ) de la position angulaire de ladite pièce excentrique (21 ) comportant un pignon d'actionnement (33) monté sur un arbre d'actionnement (32), ledit dispositif de commande (31 ) comportant en outre au moins un pignon intermédiaire étagé (36) comprenant au moins un premier et un deuxième étages formés chacun par un pignon (37, 38), le pignon (37) dudit premier étage engrenant avec ledit pignon d'actionnement (33) et le pignon (38) dudit deuxième étage engrenant avec ladite couronne dentée d'excentrique (28).
