TRANSMISSION DEVICE OF AN ENGINE, PARTICULARLY FOR AN ENGINE WITH VARIABLE COMPRESSION RATE AND/OR VARIABLE DISPLACEMENT

摘要

The invention relates to a transmission device (1), particularly for an engine with variable compression rate and/or variable displacement. Said device includes, in a cylinder housing: - a combustion piston (2), capable of moving in a combustion cylinder of the engine and secured to a transmission member (3); - a gear (5) engaging with a first rack of the transmission member (3) and proving transmission of the movement between the combustion piston (2) and a crankshaft of the engine; - a connecting rod engaging, at a first end, with the gear (5) and, at a second end, with the crankshaft; and - a control member (7) engaging with the gear (5) and secured to a control piston (12). The transmission device (1) is characterized in that the combustion piston (2) and the transmission member (3) are slidably linked with the cylinder housing (100) in a main direction.
