<p>The invention concerns a mechanical transmission device for a variable cylinder capacity engine comprising at least a cylinder (10) wherein moves a piston (2), which is integral in its lower portion with a transmission member (3) co-operating through a small-sized rack (37) with a roller bearing guide device (4) and through another large-sized rack (35) with a sprocket wheel (5) linked to a connecting rod (6), a control member (7) comprising a large-sized rack (73) co-operating with the sprocket wheel (5), means for fixing (24, 31) the piston (2) on the transmission member (3) which provide a preload for clamping it and ensure its centring, linking means (11, 12; 71, 72) for rigidifying the transmission (3) and control (7) members and for increasing the flexural strength of the teeth of the large-sized racks (35, 73), and means for lightening (56) the sprocket wheel (5) which maintain its rigidity and load capacity.</p> |
