Abstract
Die Erfindung bezieht sich auf eine Axialkolbenmaschine (1) mit einem Zylinderblock (2), in welchem Zylinderbohrungen (3) vorgesehen sind, in denen Kolben (4) bewegbar geführt sind, die sich zur Ausführung einer Hubbewegung an einer Schräg- oder Taumelscheibe (9) abstützen, die zwischen einer Schwenkendstellung minimalen Durchsatzvolumens und einer Schwenkendstellung maximalen Durchsatzvolumens um eine Schwenkachse (24) schwenkbar gelagert ist, wobei die Schwenkachse (24) bezüglich der von den Kolben (4) ausgeübten resultierenden, gegen die Schräg- oder Taumelscheibe (9) gerichteten Kolbenkraft (Kr) so versetzt (eK) ist, daß die resultierende Kolbenkraft (Kr) ein auf die Schräg- oder Taumelscheibe (9) einwirkendes erstes Drehmoment (M1) erzeugt. Erfindungsgemäß ist ein Federelement (27) vorgesehen, das ein auf die Schräg- oder Taumelscheibe (9) entgegen dem ersten Drehmoment (M1) einwirkendes zweites Drehmoment (M2) erzeugt. The invention relates to an axial piston machine (1) with a cylinder block (2), in which cylinder bores (3) are provided, in which pistons (4) are movably guided, which are used to perform a lifting movement on a swash plate or swash plate (9 ), which is pivotably mounted between a swivel end position of minimum throughput volume and a swivel end position of maximum throughput volume about a swivel axis (24), the swivel axis (24) with respect to the resulting result exerted by the pistons (4) against the swashplate or swash plate (9) directed piston force (Kr) is offset (eK) so that the resulting piston force (Kr) generates a first torque (M1) acting on the swash plate or swash plate (9). According to the invention, a spring element (27) is provided which generates a second torque (M2) acting on the swash plate or swash plate (9) against the first torque (M1).
