<p>A transmission device having power splitting. In the first driving range, the mechanical power branch transmits torque from the ring gear to the additional fixed gear by the fixed gear. In this case, power branches from the ring gear. The hydrostatic power branch branches from the second sun gear. The hydrostatic branch transmits power from the first to the second hydraulic unit. The first and second hydraulic units act respectively as a pump and a motor. On one of the hydrostatic shafts, the mechanical and hydrostatic powers are added and transmitted to the output. In the second driving range, power from the planet carrier partially branches to the ring gear and passes to the hydrostatic shaft for the second hydraulic unit. An auxiliary shaft can be coupled by a gear to a fixed gear operatively connected to a shaft of the power splitting device.</p> |
