ABSTRACT:
A load-splitting transmission has a housing in which are journaled about fixed axes a central shaft and two outer shafts. One end of the central shaft is connected to the drive and the other end of the central shaft, which is rotatable relative to the drive end, is connected to a load. The two outer shafts are each constituted as an outer tube shaft extending a part of the length of the respective outer shaft and a central torsion or core shaft extending the full length. A plurality of sets of gears are provided, each including a central gear on the central shaft and an outer gear on each of the outer shafts and meshing with the central gear. Synchromesh clutches can connect the various gears to the respective shafts for shifting. In addition at least some of the gears may be limitedly angularly displaceable on the respective shafts to compensate for misalignment and prevent gear clashing.
