A mechanical transmission device for a variable cylinder capacity engine includes 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 ) having a large-sized rack ( 73 ) co-operating with the sprocket wheel ( 5 ), elements for fixing ( 24, 31 ) the piston ( 2 ) on the transmission member ( 3 ) which provide a preload for clamping it and ensure its centring, linking elements ( 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 elements for lightening ( 56 ) the sprocket wheel ( 5 ) which maintain its rigidity and load capacity. |
