Abstract

Hydrostatic unit for driving an industrial truck with a pump, a hydrostatic propulsion unit and additional users of hydraulic energy, wherein the pump is located on an axle body of a drive axle. A control valve for the pressurization of the propulsion unit and at least one control valve for the pressurization of an additional user are located on the axle body or at least partly integrating into the axle body. In one embodiment, the axle body is a control seat receptacle of the pump and at least one traction motor of the hydrostatic propulsion unit. The control valves can be actuated electrically or hydraulically.
