A hydrostatic axial piston pump of swashplate construction, which is also configured to be operated as a motor, has a stationary control plate against which a rotating cylinder drum is tensioned. During operation, a tilting tendency of the cylinder drum arises in the direction of that quadrant of the control plate which is operatively connected to the first part of the displacement stroke of the pistons. The control plate has a supporting device configured for the cylinder drum. The supporting device is arranged adjacent to an outer edge of the control plate in the first quadrant thereof. The supporting device is configured to be formed by a hydrostatically relieved additional field.

Hydrostatic axial piston machine

A hydrostatic machine includes a housing and a drive shaft. The housing has an inner housing part, configured to receive a force flow, an outer housing part, configured to seal and damp, and a housing floor. The drive shaft is configured, on an input side, to pass coaxially through the housing floor and is configured, on an output side, to pass coaxially through a swash plate. The drive shaft is connected to a cylinder drum in a rotationally fixed manner. The hydrostatic machine is configured in a weight-saving manner and is configured such that propagation of vibrations in the hydrostatic machine, and noise generation therefrom, are reduced. To this end, the drive shaft is further configured to pass only partially through the inner housing part and is rotatably mounted in the housing floor and the inner housing part.
