Abstract
An axial piston machine includes a housing having a casting which is optimized with respect to casting. An insert ring which is optimized with respect to a pressure load is formed in the bottom of the housing. The insert ring is configured to be used with such an axial piston machine.
Claims16
An axial piston machine, comprising:
- a pump housing;
- at least one cylinder barrel mounted in the pump housing and having a multiplicity of pistons each delimiting a working space and being supported on an adjustable swashplate;
- a control disk arranged at an end in the pump housing and configured to alternately connect the working space to a low-pressure and a high-pressure duct;
- a drive shaft configured to connect to the at least one cylinder barrel to rotate conjointly;
- and
- an insert ring, on which the drive shaft is mounted and in which a high-pressure duct section is formed, wherein:
- the housing is approximately cup-shaped with a cup bottom formed in sections by the insert ring;
- the high-pressure duct section has an axial orifice region on the control-disk side and has a radial or axial orifice region on the high-pressure duct side;
- and
- the insert ring is optimized for pressure loading by configuration, selection of material or production method.
