The unit also comprises an epicyclic train which adds the power of the hydrostatic motors, the first motor being associated with the shaft of the sun gear and the second motor being associated with the shaft of the crown gear of the epicyclic train. A first brake and a second brake are respectively associated to the shaft of the sun gear and to the shaft of the crown gear.
