摘要： A control system for a variable-ratio transmission (1) of the type in which the variation is controlled by displacing two elements of the transmission relative to one another along a displacement axis, and in which these elements can give rise to a thrust having a component along the displacement axis, which component is correlated with the torque transmitted by the transmission, is described. The system includes operative control means interposed between actuator means and at least one of the two transmission elements in order to instigate the displacement upon the operation of the actuator means; resilient means (106a, 106b) are also interposed between the operative control means and the actuator means and can yield resiliently as a result of the thrust component along the displacement axis when the said component exceeds a predetermined threshold value corresponding to a value of the maximum torque transmitted by the transmission.

摘要： An imbricate type epicyclic reduction gear comprises a drive input shaft (3), on which a sun gear (6), a plurality of planetary gears (7) having a first set of teeth (9) which are rotatingly engaged between the sun gear (6) and a first fixed ring gear (11) are mounted. There is provided on the planetary gears (7) a second set of teeth (10) which is adjacent to and coaxial with the first set of teeth, but having a different diameter therefrom, and which is engaged with a second ring gear (12) which is associated with a drive output shaft (4). The first and the second sets of teeth are of the helical type having mutually different helix angles (A, B) and the planetary gears can be moved axially relative to the sun gear and the ring gears.
