Hydrostatic Axial Piston Machine

摘要

A hydrostatic axial piston machine defines an adjustable displacement volume and includes a housing, a cylinder drum, a plurality of working pistons, a pivot cradle, and a plain bearing. The working pistons are received in the cylinder drum so as to be axially displaceable, and are supported on a sliding surface of the pivot cradle. The pivot cradle is configured to adjust the displacement volume, and is pivotably mounted on the plain bearing. The plain bearing is fixed with respect to the housing. The hydrostatic axial piston machine is configured to form at least one first hydrostatic relief pressure field between the plain bearing and the pivot cradle.

1. A hydrostatic axial piston machine, defining an adjustable displacement volume, and comprising:
a housing; a cylinder drum; a plain bearing fixed to the housing; and a pivot cradle that is pivotably mounted on the plain bearing to enable formation of at least one first hydrostatic relief pressure field between the plain bearing and the pivot cradle, the pivot cradle defining a sliding surface and being configured to adjust the displacement volume; a plurality of working pistons received in the cylinder drum so as to be axially displaceable, and supported on the sliding surface of the pivot cradle; and a first pressure medium source; the hydrostatic axial piston machine further defining a first pressure medium flow path from the first pressure medium source to the first hydrostatic relief pressure field, the first pressure medium flow path including an adjustable throughflow cross section.
