Abstract
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.
