Abstract
Change of progressive gears by trapezoidal belts, characterized by the fact that extendable pulleys, arranged on the drive shaft and the driven shaft, interconnected by trapezoidal belts, drive one of the two central wheels of a planetary gear, while at the same time toothed wheels, trapezoidal belts or chains form a second transmission of a constant rotation ratio between the drive shaft and the planetary gear, which drives the satellites of the latter around the common center of rotation of the center wheels.
