Clip-fastened raceway for a variable compression ratio engine

Clip-fastened raceway for a variable compression ratio engine (10), said engine comprising a cylinder case (100) receiving a transmission member (3) provided with a rack, to which are fastened a combustion piston (2), a control member (7) provided with a rack and connected to a hydraulic double-acting control actuator (8), a toothed wheel (5) which cooperates, on the one hand with the transmission member (3), and on the other hand with the control member (7) to transmit the mechanical work produced by the combustion on the combustion piston (2) by means of a connecting rod (6) connected to a crankshaft (9), characterized in that it comprises:

• at least one curved segment (51) whose outer surface (52) cooperates with a raceway housed in the transmission member (3) or in the control member (7) of the variable compression ratio engine (10) and whose inner surface (53) is maintained in contact with a curved outer surface (54) housed in the toothed wheel (5) of said engine;
• at least one clip (55), housed in at least one of the ends of the curved segment (51) and fastened to one or the other of the ends of the curved outer surface (54) housed in the toothed wheel (5) and hooking onto a hook or protrusion (56) which said wheel comprises in the vicinity of said end of its curved outer surface (54), said hook or protrusion being complementary to that of the clip (55) so as to be able to cooperate with the latter.
