Claims (5)

1. Axialkolbenmaschinen in den beiden Ausführungen als Hydropumpe oder Hydromotor in den Bauarten Taumelscheibe, Schrägscheibe sowie Schrägachse in Konstant- oder Verstellausführung dadurch gekennzeichnet, daß die Kolbenfläche des Kolbens (1) durch sinnvoll angebrachte Längsbohrungen (4) sowohl auf der Kolbenoberseite als auch auf der Kolbenunterseite mit Hydrauliköl beaufschlagt werden kann (doppelt wirkend), sodaß neben den bisher ausschließlich erzielten Druckkräften auch Zugkräfte auf die Kolbenstange (2) erzeugt werden können.1. Axial piston machines in the two versions as a hydraulic pump or hydraulic motor in the types swash plate, swash plate and inclined axis in constant or adjustable design, characterized in that the piston surface of the piston ( 1 ) through sensible longitudinal bores ( 4 ) both on the piston top and on the Hydraulic oil can be applied to the underside of the piston (double-acting), so that, in addition to the compressive forces previously only achieved, tensile forces can also be generated on the piston rod ( 2 ). 2. Axialkolbenmaschinen nach Anspruch 1, dadurch gekennzeichnet, daß der Raum unter dem Kolben mit einer Abdichtung und einer Führung (6) versehen ist, die eine Beaufschlagung mit Hydraulikflüssigkeit erlauben.2. Axial piston machines according to claim 1, characterized in that the space under the piston is provided with a seal and a guide ( 6 ) which allow exposure to hydraulic fluid. 3. Axialkolbenmaschinen nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Kolbenunterseite durch Längsbohrungen (4), gesteuert durch eine geschlitzte Steuerscheibe (5) mit Hydraulikflüssigkeit beaufschlagt werden kann.3. Axial piston machines according to claim 1 and 2, characterized in that the piston underside through longitudinal bores ( 4 ), controlled by a slotted control disc ( 5 ) can be acted upon with hydraulic fluid. 4. Axialkolbenmaschinen nach einem der Ansprüche 1 bis 3, dadurch gekennzeichnet, daß die zusätzliche auftretenden Zugkräfte durch geeignete Maßnahmen übertragen werden. Dies kann beispielhaft durch radiale, geschlitzte Bohrungen (8) zur Aufnahme der in einem Kugelkopf (7) endigender Kolbenstange (2) wie in Abb. 2 geschehen, sodaß die auch die radialen Bewegungen beim Umlauf auf der ellyptischen Bahn möglich werden. Eine ähnliche Lösung stellt der den Kugelkopf (7) umfassende Gleitschuh (8) dar, der nach Abb. 3 in einer T-Nut läuft.4. Axial piston machines according to one of claims 1 to 3, characterized in that the additional tensile forces occurring are transmitted by suitable measures. This can be done, for example, by radial, slotted bores ( 8 ) for receiving the piston rod ( 2 ) ending in a spherical head ( 7 ), as in Fig. 2, so that the radial movements when rotating on the elliptical path are also possible. A similar solution is provided by the slide shoe ( 8 ) comprising the ball head ( 7 ), which runs in a T-slot according to Fig. 3. 5. Axialkolbenmaschinen in den Bauarten Taumelscheibe und Schrägscheibe nach einem der Ansprüche 1 bis 4, dadurch gekennzeichnet, daß als Zwischenglied, wie z. B. nach Abb. 4 und 5 eine Scheibe (13) eingefügt wird, die einerseits die radialen Relativbewegungen der Kolbenstange (2) beim Umlauf aufnimmt, andererseits drehbar derart an der Taumelscheibe (12) befestigt ist, daß auch die Zugkräfte auf diese übertragen werden.5. Axial piston machines in the types swash plate and swash plate according to one of claims 1 to 4, characterized in that as an intermediate member, such as. B. according to Figs. 4 and 5, a disc ( 13 ) is inserted, which on the one hand receives the radial relative movements of the piston rod ( 2 ) during rotation, on the other hand is rotatably attached to the swash plate ( 12 ) such that the tensile forces are transmitted to it .
