ABSTRACT:
An automatic transmission with a section controlling the transmission ratio between an input shaft and an output shaft. The section comprises a central shaft carrying at least one radially extending shaft with a first set of gear wheels drivable by the input shaft. Depending on the desired torque-speed ratio, the gear wheels can cooperate with a second set of gear wheels which in a torque-dependent fashion are spring-loaded so as to be locked from rotation. The direction of rotation of the output shaft can be reversed with an adjusting mechanism.
