ABSTRACT:
A change-speed transmission which includes an input shaft and an output shaft which are drivingly connected by a forward and rearward planetary gear system. The forward planetary gear system includes two planetary gears one of which meshes merely with a sun gear with the other planetary gear meshing with a further sun gear as well as with a ring gear. The planetary gears are carried by a double carrier which is drivingly connected with one transmission member of the rearward planetary gear system with the ring gear being drivingly connected with another member of the rearward planetary gear system by way of respective torque transmitting coupling trains. A change-speed clutch for producing a direct transmission of the rearward planetary gear system is operatively connected with the double carrier which is also drivable through a gear shifting clutch by way of the input shaft. The sun gear of the planetary gear system which does not mesh with the ring gear is positionally arranged between the other sun gear of the forward planetary gear system and the output shaft with the sun gear being drivable through a further gear shifting clutch by way of the input shaft.
