Abstract
The invention provides a serial continuously variable transmission () comprising an input shaft () with a first pulley sheave set () of a first CVT stage and an output shaft () with a fourth pulley sheave set () of a second CVT stage, and a second () and third () pulley sheave set, rotating around a common axis and mutually rotationally secured the respective inner pulley sheave of the second and the third pulley sheave set being interconnected and combined into an assembly which is shiftable along and rotatable therearound the common axis (), while the respective diameters of the pulley sheaves of the second CVT stage are greater than the diameters of the sheaves of the first CVT stage, in such a way that the effective running radius of the driving belt of this second stage will be greater than the effective running radius of the driving belt of the first stage.
