<p>A mechanical transmission (10) in particular for toy automobiles comprises a substantially cylindrical element (19) rotating axially in kinematic connection with the motion output (22) of the transmission. On said cylindrical element (19) are fitted in a rotating manner toothed gears (17,18) each of which is in kinematic connection at a different ratio with the motion input of the transmission. Inside the cylindrical element (19) is axially sliding between the gears (17,18) by control means (26) a cursor (24) for selective sequential radial engagement between the cylindrical element (19) and the gears (17,18) so as to realize motion transmission with a different ratio between input and output through selection of engagement between the cylindrical element and a gear. <IMAGE></p> |
