ABSTRACT:
An automatic continuously variable transmission with a section controlling the transmission ratio between an input shaft and an output shaft. The controlling section comprises a central shaft carrying at least one radially extending shaft with a rotatable and slidable conical body with a concave-conical outer circumferential surface. Depending on the desired-torque-speed ratio, controlled by an axial thrusting force generated by a speed-dependent clutch, the body can cooperate with a spring-loaded annular body rotatable around the central shaft and having a convex-conical inner circumferential surface. The direction of rotation of the output shaft can be reversed by means of an adjustment mechanism.
