HYDROSTATIC AXIAL PISTON MACHINE

摘要

The invention relates to a hydrostatic axial piston machine having a housing, having a drive shaft, to which a flange disc is fastened in a rotationally fixed manner, and having a swash plate, to which a rotor disc, driven by the drive shaft or the flange disc, is rotatably mounted, and having a plurality of displacement units arranged distributed between the flange disc and the rotor disc and around the axis of the drive shaft, each displacement unit comprising a cylinder sleeve and a piston which extends into the cylinder sleeve and has a ball head and a spherical joint head which extends into the cylinder sleeve, wherein during operation, the piston plunges more or less far into the cylinder sleeve. The aim of the invention is to improve the degree of effectiveness in a hydrostatic axial piston machine having the specified features, over the entire operating range, and thus to enlarge the previous conversion range and in particular to improve the startup behavior in operation or in use as a hydraulic motor. According to the invention, said aim is achieved in that the joint heads are located on the flange disc and the piston is located on the rotor disc.
