Abstract

A hydraulic machine is proposed, with a drive shaft rotating around a center axis, a drive wheel at a first end of the drive shaft, via which forces, which are characterized by a force component running largely vertical to the center axis, are led to the drive shaft, a second, opposite end of the drive shaft with a pump unit, which is characterized by a first rotating pump element connected to the drive shaft and a fixed pump element which works in conjunction with the first pump element, and with a bearing unit for the drive shaft, the hydraulic machine is characterized by the fact that the bearing unit (33) is offset to the line drawn by the middle axis (13) when the drive shaft (27) is not under load, where the bearing unit (33) is positioned in the direction of the force components relative to the center axis (13).
