Hydrostatic Variable Displacement Axial Piston Machine, in particular Hydrostatic Variable Displacement Axial Piston Motor

摘要

A hydrostatic axial piston machine includes a swashplate with an oblique surface formed thereon. Working pistons, which revolve and are supported by the oblique surface, are axially positioned on the swashplate with respect to a drive shaft. An adjusting cylinder, coupled to the swashplate, is configured to produce a pivoting moment and pivot the swashplate about a pivoting axis. Displacement of the working cylinders per revolution around the drive shaft is adjustable by adjusting a pivoting angle of the oblique surface. The adjustment of the pivoting angle is configured to pass beyond zero degrees, such that the direction of rotation of the drive shaft is changeable. The pivoting axis is at a distance from an axis of rotation of the drive shaft, such that an internal counter pivoting moment counteracting the pivoting moment is produced during operation of the axial piston machine when the working pistons are subjected to pressure.

主权项

1. A hydrostatic axial piston machine, comprising:
a drive shaft configured to rotate about a rotation axis; a pivoting cradle; an adjustment device coupled to the pivoting cradle and configured to produce a pivoting moment that pivots the pivoting cradle about a pivoting axis in a first direction, wherein the pivoting cradle is configured to be pivoted from positive pivoting angles to negative pivoting angles through a pivoting angle of 0 degrees; and a cylinder drum configured to:
revolve with the drive shaft such that the cylinder drum is secured against twisting; andguide working pistons supported on the pivoting cradle; wherein the pivoting axis is located at a distance from the rotation axis, such that a counter pivoting movement on the pivoting cradle is produced via support of the working pistons.
