Power branching transmission, has internal gear staying in effective connection with output of branch section attached to variator transmission branch, and planetary carrier that is driven by step gear of mechanical transmission branch

摘要

The transmission has an additional summation gear formed as a differential gear and is arranged upstream to a stepless gear (GV). The additional summation gear has a drive element i.e. sun gear, that is connected to an input of the stepless gear, an internal gear and a planetary carrier. The internal gear stays in effective connection with an output of a branch section (K) attached to a variator transmission branch (ZV). The planetary carrier is driven by a step gear (GS) of a mechanical transmission branch (ZM).
