  • Patent number: 9611894
    Abstract: A clip-fastened raceway for a variable compression ratio engine includes: at least one curved segment whose outer surface cooperates with a raceway housed in the transmission member or in the control member of the variable compression ratio engine and whose inner surface is maintained in contact with a curved outer surface housed in the toothed wheel of the engine; at least one clip, housed in at least one of the ends of the curved segment and fastened to one or the other of the ends of the curved outer surface housed in the toothed wheel and hooking onto a hook or protrusion which the wheel includes in the vicinity of the end of its curved outer surface, the hook or protrusion being complementary to that of the clip so as to be able to cooperate with the latter.

  • Publication number: 20110283969
    Abstract: The elastic fixing for a piston (2) of a variable compression ratio engine (10) includes at least one metal rod (15) kept under tension between the piston (2) and the transmission member (3) and which applies a strong contact pressure between the base of the piston (2) and the top face of the transmission member (3), the piston (2) being tightened according to a previously calculated angle enabling the metal rod (15) consisting of a stud (16) to be subjected to a desired tension force and the tightening prestress to be reached between the piston (2) and the transmission member (3), and indexed in rotation relative to the transmission member (3), by an additional tightening which does not significantly increase the tightening pre-stress, the stud (16) continuing to elongate with the same tension force by plastic deformation.
