摘要： Pulley assembly for a continuously-variable vehicle transmission, comprising a support element having an axis, a first half-pulley rotationally connected to the support element, a second half-pulley facing the first half-pulley to define a seating adapted to house a drive belt, the second half-pulley being axially and circumferentially mobile in relation to the support element, and cam means functionally inserted between the second half-pulley and the support element to control the position of the second half-pulley. The cam means define a plurality of circumferential cavities carried by a peripheral portion of the second half-pulley, said cavities being defined by the first and second sides which are transverse to axis, and comprise a plurality of cam-followers which are connected to the support element and housed in the corresponding circumferential cavities to cooperate selectively with the first and second sides.

摘要： A pulley for a continuously variable transmission is provided with a fixed half-pulley fitted on a supporting shaft and a mobile half-pulley, which is able to slide towards the fixed half-pulley under the thrust of a spring, so as to define a V-shaped race of variable amplitude. The pulley is further provided with a device for compensating the axial thrust, said device being constituted by a cam and a cam follower, which are coupled in contact with one another to impart an additional axial thrust on the mobile half-pulley in response to a torque acting on the pulley. The cam is defined by a tubular body made of plastic material co-moulded on the supporting shaft, whilst the cam follower is made of a single piece with the mobile half-pulley.
