Abstract
A friction stepless speed change device includes an input shaft, an output shaft, a countershaft provided in parallel with the input and output shafts on one side thereof, two rocking arms rockable about the countershaft, a cylindrical driven rotary assembly rotatably supported on free ends of the rocking arms to enclose the input shaft, a set of driving friction discs rotating together with the input shaft, and a set of driven friction discs rotating together with the driven rotary assembly. The sets of the driving and driven friction discs are wedge-engaged with each other. A gear fixed to the driven rotary assembly is in mesh with one gear of an intermediate gear assembly, and a gear arranged on a planet carrier is in mesh with the other gear of the intermediate gear assembly. Planet gears journaled on the planet carrier are in mesh with an internal gear integrally fixed to the input shaft, and a sun gear integrally formed on the output shaft is in mesh with the planat gears.
