Abstract

A CVT 1 has a first in-/output shaft (3) with a first wheel (5) attached to it, that is constituted by a pulley (5) consisting of two conical sheaves (7) and (9) and a second in/output shaft (11) with a second wheel (13) attached to it, which is constituted by a gear. The CVT 1 furthermore has transmission means (15) constituted by an intermediate shaft (17) wit h a third and fourth wheel (19, 21) attached to it, being a further pulley (19) and a further gear (21) that meshes with gear (13), as well as a pushbelt (27), that is wrapped around the pulleys (5) and (19). For changing the transmission ratio the CVT 1 has displacement means (29) that can move the intermediate shaft (17) along a circular arc, arrow (33), changing the distance between t he shafts (3) and (17). For moving the shaft (17) it is connected to the shaft (11) through connection means (35). This connection means (35) is connected to the displacement means (29), which can for instance be of the electromechanical type.
