ABSTRACT:
A power transmission having a four-shaft double planetary gear (I, II), which is driven on the one hand via a turning gear (WG) and on the other via a variable-displacement gear (HG) and is connectable on the power take-off side via selectable ratio gears via controllable clutches (K1A-K7A) to a power take-off shaft (AW3) and is connectable on the power take-off side retroactively via two of the selectable ratio gears (G4, G5) by means of a startup clutch (K0B), as a result of which with the turning gear (WG) disengaged, a fully hydraulic startup range is provided, and the other gear ranges are mechanically-hydraulically split in terms of power when the turning gear is engaged.
All the clutches are double claw clutches.
The startup clutch has a special construction, with a sliding sleeve.
The transmission is especially suitable for agricultural machines, because it is fully reversible. Other versions are shown.
