Abstract
Reduction-distribution unit for gearshift units, particularly for industrial machines, including a first hydrostatic motor and a second hydrostatic motor which are operatively associated for the transmission of the motion to the axles. 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.
