Clip-fastened raceway for a variable compression ratio engine

摘要

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.

主权项

1. A clip-fastened raceway for a variable compression ratio engine, said engine comprising a cylinder case receiving a transmission member provided with a rack, to which are fastened a combustion piston, a control member provided with a rack and connected to a hydraulic double-acting control actuator, a toothed wheel which cooperates with the transmission member, and with the control member to transmit the mechanical work produced by the combustion on the combustion piston by a connecting rod connected to a crankshaft, the raceway comprising:
at least one curved segment having an outer surface which cooperates with a raceway housed in the transmission member or in the control member of the variable compression ratio engine, the curved segment having an inner surface which is maintained in contact with a curved outer surface housed in the toothed wheel of said engine; at least one clip, housed in at least one end of the curved segment and fastened to one or other of ends of the curved outer surface housed in the toothed wheel and hooking onto a hook or protrusion which said wheel comprises in a vicinity of said end of the curved outer surface, said hook or protrusion being complementary to the at least one clip so as to be able to cooperate with the at least one clip.
