Definitions
- the invention relates to an axial piston machine and a control disk for such an axial piston machine according to the preamble of claims 1 and 15, respectively.
- An axial piston machine of this type is e.g. B. described in DE 100 30 147 AI, both as an axial piston machine with a constant throughput volume and with a variable throughput volume.
- a change in the throughput volume is achieved in this known construction in that the cylinder drum and the control disk are pivoted in the plane axis containing the central axes of the drive disk and the cylinder drum.
- a driver connection with positively interlocking positioning elements between the control disk and the housing or a control block replacing a housing wall can be provided.
- the pivoting is carried out in a circular arc around the intersection of the central axes and in the Schr gachsenebene extending guide in which the control disc is pivotally guided.
- the invention is based on the object of designing an axial piston machine and a control disk for such an axial piston machine while ensuring a simple construction so that a step-like change in the throughput volume is possible.
- the invention is based on the knowledge that an adjustment of the control disk instead of its pivoting in a guide by an offset of the control disk can be reached, which can be achieved by remounting the control disk by rotating it through 180 ° about its central guide axis.
- two positions of the control disk which are offset with respect to one another in the inclined axis plane, can be realized, in which the angle enclosed between the central axes of the drive disk and the cylinder drum is different and therefore the throughput volume is different.
- the positioning element arranged on the control disk is transversely offset with respect to the central guide axis in the plane of the inclined axis, the control disk being optionally mountable in two positions offset by 180 ° to one another.
- the positioning element arranged on the control disk is arranged offset with respect to the guide center axis in the inclined axis plane.
- Both configurations according to the invention enable a lateral displacement of the control disk, which leads to a different volume setting taking into account the inclined axis arrangement.
- One of these two volume settings can be brought about either by remounting the control disk by rotating it through 180 ° or by mounting the control disk in one of its two positions during initial assembly. In this way, the desired throughput volume can be taken into account during assembly or initial assembly of the axial piston machine.
- the size of the throughput volume difference can be determined by the size of the offset dimension by which the positioning element arranged on the control disk is offset with respect to the guide center axis.
- Both configurations according to the invention are suitable for differently adjustable throughput volumes. hereby it is possible, when assembling the axial piston machine, to determine whether the throughput volume should be larger or smaller with respect to a desired throughput volume range.
- An offset of less than 10 °, in particular about 3 °, enables large flow cross sections to be realized for the flow channels in the control disk and in the connecting part. Flow losses can thus be reduced and the speed stability and the efficiency of the axial piston machine can be improved.
- the invention is also suitable in combination with an axial piston machine whose throughput volume can be adjusted by pivoting the control disk by means of an adjusting device.
- the configuration according to the invention on the one hand enables the adjustment range to be shifted from minimal to e.g. 0 ° or maximum up to e.g. 32 ° and on the other hand an increase in the adjustment range if the control disc is positioned in such a way that the displacement is increased by the offset.
- the configuration according to the invention is therefore suitable both for those axial piston machines in which the control disc is immovable in its assembled position and for such axial piston machines in which the control disc is displaceable in a circularly curved guide around the intersection of the central axes of the drive pulley and the cylinder drum in order to change the throughput volume is.
- the throughput volume in the area of the guide is infinitely variable.
- the configuration according to the invention is preferably suitable for changing the throughput volume in the range of the maximum limit of the adjustment range.
- the advantages described above can also be achieved if the configuration according to the invention is combined with an axial piston machine whose adjustment range is smaller than the increased adjustment range which can be achieved by the offset of the control disk.
- the adjusting device of the axial piston machine z. B. designed for an adjustment range from 0 ° to 26 °, then can be adjusted by specifically mounting or remounting the control disc according to the invention in one position, the swivel range from 0 ° to 26 ° and in the other position an adjustment range increased by the amount of offset set, which ends before the minimum setting of 0 °.
- an offset of z. B. about 3 ° can be adjusted in the latter case, an adjustment range of 6 ° to 32 °.
- a raised part on the side of the control disk facing the cylinder block is suitable, which interacts positively with a correspondingly shaped end face of the control block.
- a rotationally symmetrically curved design of the guide element and the end face of the cylinder drum interacting with it in a form-fitting manner is required.
- a positioning engagement known per se between a recess and a pin encircling it is well suited as a positioning device for positioning the control disk while ensuring a simple and inexpensive construction.

- the offset angle W2 is less than about 10 ° and is preferably about 3 °.
- the positioning device 19 also comprises a contact surface 19d facing the control disk 18 on the connection part 5.
- the control disk 18 lies with a contact surface 18a on its end face facing the connection part 5 on the contact surface 19d and is thereby supported toward the side facing away from the cylinder block 12.
- the positioning device 19 is designed such that the control disk 18 can be assembled from the offset position shown in FIGS. 1 and 3 into an offset position shown in FIG. 2, in which it is rotated by 180 ° about the central guide axis 22, and vice versa.
- the reassembly of the control disk 18 into the positions shown in FIGS. 1 and 2 leads to a lateral offset of the control disk 18 and the cylinder block 12 guided thereon, this offset being twice as large as the offset a given by the offset angle W2.
- the axial piston machine 1 described so far can thus be assembled by mounting the control disk 18 in a specific mounting position or by remounting the control disk 18 in positions rotated by 180 °. In these positions of the control disk 18, the axial piston machine 1 can be set to two different throughput volumes and can be adjusted in one step.
- control disk 18 can be swiveled and locked laterally back and forth in addition to the positions described above in a swivel guide 31 extending parallel to the inclined axis plane E, the swivel guide 31 being curved around the intersection 14 of the longitudinal central axes 11, 13.

- the positioning pin 42 is mounted in the control disk 18 such that it cannot rotate with respect to the control disk 18.
- the positioning pin 42 can have inclined side sections which preferably merge into the pin sections 42c, 42d with a convex or concave shape, as shown in the drawing.
- the positioning recess 42b forms a rotary bearing 40 for the cylinder block 12. It can be a roller or slide bearing, which can have a slide bush 12a attached to one of the rotary bearing parts.
- the positioning recess 19b is arranged in the pin section 42c, its cross-sectional shape and size being adapted to the cross-sectional size and shape of the positioning element 19a and can be formed by a blind hole which is open at the end.
- the positioning recess 19b is preferably formed by a longitudinal channel and is open to a guide hole 15a receiving a central guide pin 16a. This improves the lubrication of the positioning elements 19a, 19b.
- the positioning elements 19a, 19b can be designed as in the exemplary embodiment according to FIG. 3, namely with a waist 19h on the positioning head 19e and a recess widening 19i on the edge of the hole facing the housing or connecting part 5, in order to enlarge the available swivel range.
- a sliding layer 44 made of easy-to-slide and / or wear-resistant material arranged between the control disk 18 and the cylinder block 12 can be formed by a disk which can be attached to the control disk 18, e.g. by soldering, welding or gluing.
- a hole 44a in the disk which is penetrated by the positioning pin 42 is so large that the transition region 42g has free space therein in the two offset positions.
- the guide surfaces 23a, 23b are, in contrast to the exemplary embodiment described above, flat surfaces, but they can also have a concave or convex spherical segment shape, as is the case with the exemplary embodiment described above.
- the positioning recess 42b and the pin section 42d are preferably arranged coaxially to the longitudinal central axis 13 of the cylinder block 12.
- the positioning recess 42a and the positioning pin 42c as well as the Positioning recess 19b can be offset parallel with respect to the longitudinal center axis 13 and the offset a.
- the positioning recess 42a, the pin section 42c located therein and the positioning recess 19b are rotated relative to one another with respect to the longitudinal central axis 13 by the angle W2.
- the control disk 18 can be remounted with the housing cover or connecting part 5 removed, in that the control disk 18 is lifted from the pin section 42c, rotated through 180 ° about the central axis 13 and replaced, or that the control disk 18 with the positioning pin 42 from the Positioning recess 42b is lifted, rotated through 180 ° approximately about the central axis 13 and inserted again into the positioning recess 42b. If possible, the reassembly can also be carried out by rotating the positioning pin 42 through 180 ° in the positioning recess 42b.
