摘要： A continuously-variable-ratio drive, having an input shaft; a flywheel integral with the input shaft; a drive pulley idle with respect to the input shaft and defined by two half-pulleys defining a groove of variable size for a V belt; and a centrifugal control assembly. The control assembly has a centrifugal actuating device which intervenes above a first threshold value of the angular speed of the input shaft to connect the drive pulley angularly to the flywheel by means of a friction clutch; and a speed adjusting device which is active over a second threshold value of the angular speed of the input shaft to adjust the size of the groove of the drive pulley and therefore the work diameter of the belt.

摘要： The assembly includes an input member having a radial surface and fitted integrally with a coaxial drive shaft; and a pulley fitted coaxially to and idle with respect to the drive shaft and having two half-pulleys connected to each other to rotate integrally and move axially with respect to each other, and which engage a drive belt. There is also provided a thrust-clutch member, which is connected to the drive shaft so as to rotate integrally with and move axially with respect to the drive shaft, and is located adjacent to the second half-pulley. The thrust-clutch member is adapted to move its radial surface axially into contact with the second outer radial surface of the pulley, and simultaneously moves the entire pulley to bring the first outer radial surface of the pulley into contact with the radial surface of the input member, so as to make the radial surfaces frictionally integral with each other, and exerts axial thrust on the two half-pulleys so as to determine the axial distance between them in direct relation to its own axial position; the thrust-clutch member having a position, at a maximum distance from the input member, in which the radial surfaces are detached. There is also provided a control device for varying, on command, the axial position of the thrust-clutch member.

摘要： The drive assembly has: an input member and an intermediate shaft; an axial clutch device for connecting the input member and the intermediate shaft in rotary manner; and a pulley connected in rotary manner to the intermediate shaft and defined by two half-pulleys movable axially with respect to each other and engaging a drive belt, the distance between the half-pulleys determining the winding radius of the belt. A push member, movable axially, along the intermediate shaft, between two limit positions, exerts thrust on the two half-pulleys to determine, in direct relation with its own axial position, the axial distance between the two half-pulleys, and alternatively exerts thrust on the clutch device to release the clutch device when moved axially in the direction increasing the distance between the half-pulleys. A control device is also provided to vary, on command, the axial position of the push member.
