Power split drive with a hydrostatic and a mechanical power split

摘要

The transmission (1) has a power flow between a hydrostatic power branch (2) and a mechanical power branch (3). The power flow is guided via a connecting shaft (22) e.g. hollow shaft, which compensates an axial offset between a hydrostat shaft (18) of the hydrostatic power branch and a shaft (20) of the mechanical power branch. A spring device (27) is arranged partially within the connecting shaft. Tooth profiles (23, 25) of the connecting shaft are formed as curved outer teeth that are respectively engaged in tooth profiles (24, 26) of the shafts (18, 20).
