A hydraulic axial piston machine, comprising:
- a housing;
- a drive shaft rotatably mounted in the housing and having a drive shaft axis;
- a first swashplate configured to pivot about a first pivot axis to vary a first inclination relative to the drive shaft axis, the first swashplate defining a central plane extending through a center of the first swashplate perpendicular with respect to the first pivot axis and extending through the drive shaft axis;
- a first actuating piston with a first actuating piston longitudinal axis, the first actuating piston extending at least approximately parallel to the drive shaft axis with the first actuating piston longitudinal axis spaced apart from the central plane, the first actuating piston including:
- a first longitudinal end engaging the first swashplate so as to adjust the first swashplate;
- and
- a second opposite longitudinal end delimiting a first actuating chamber into which control fluid flows to pivot the first swashplate in one direction and out of which control fluid is displaced when the first swashplate pivots in the other direction;
- a first regulating valve configured to regulate flow of the control fluid into and out from the first actuating chamber;
- a first elongate feedback element arranged on the first actuating piston and configured to input a first actual position of the first actuating piston and a first actual oblique position of the first swashplate into the first regulating valve to control the first regulating valve;
- a second swashplate configured to pivot about a second pivot axis to vary a second inclination relative to the drive shaft axis, the central plane extending through a center of the second swashplate perpendicular with respect to the second pivot axis;
- a second actuating piston with a second actuating piston longitudinal axis, the second actuating piston extending at least approximately parallel to the drive shaft axis with the second actuating piston longitudinal axis spaced apart from the central plane, the second actuating piston including:
- a third longitudinal end engaging the second swashplate so as to adjust the second swashplate;
- and
- a fourth opposite longitudinal end delimiting a second actuating chamber into which control fluid flows to pivot the second swashplate in one direction and out of which control fluid is displaced when the second swashplate pivots in the other direction;
- a second regulating valve configured to regulate flow of the control fluid into and out from the second actuating chamber;
- and
- a second elongate feedback element arranged on the second actuating piston and configured to input a second actual position of the second actuating piston and a second actual oblique position of the second swashplate into the second regulating valve to control the second regulating valve, wherein:
- the first feedback element has a first feedback element longitudinal axis and is positioned such that the first feedback element longitudinal axis and the first actuating piston longitudinal axis define a first plane which is not perpendicular to the first pivot axis of the first swashplate, and
- the second feedback element has a second feedback element longitudinal axis and is positioned such that the second feedback element longitudinal axis and the second actuating piston longitudinal axis define a second plane which is oriented differently from the first plane.
