ABSTRACT Planetary change-speed gear unit shiftable under load A planetary change-speed gear unit shiftable under load, in particular for motor vehicles, comprising an automatic gear control system and several coupled planetary gear sets, together with clutches and brakes for attaining drive lines of different gear ratios, in which only two clutches A, B, disposed for example at the drive shaft, are in the form of clutches capable of actuation under load, and the drive torque is in principle transmitted selectively by way of two drive lines. The remaining clutches and brakes can then be engaged at any time when they are not involved in the torque transmission. By suitable choice and positioning of the coupled planetary gear sets, clutches and brakes in relation to the two clutches, capable of actuation under load, the individual constructional elements are utilised for a plurality of purposes, and provide a simple construction with appropriate gear ratios, and a comparatively large number of gear positions.
