Abstract

The invention relates to an axial piston machine (1) having a pivot bearing (13) which is composed of two pivot bearing parts (13b, 13c) and has a pivot axis (13a) for a swash plate (12), having a gap (a) which is rounded and curved in the shape of a circular arc section between the pivot bearing parts (13b, 13c), and having a cage segment (15) arranged in said gap (a), wherein the cage segment (15) is guided by an angular guide element (19). The guide element (19) has a first guide limb (19a) which extends transversely with respect to the gap (a), projects beyond the latter, is mounted by means of a first rotary bearing (21) so as to be rotatable about its first rotational axis (21b) which extends parallel to the pivot axis (13a) and by means of a first longitudinal guide (23) so as to be moveable on the cage segment (15), and is connected in its one end region to a second guide limb (19b) which extends transversely with respect to the pivot plane (E4) of the first guide limb (19a) and which is rotatably connected by means of a second rotary bearing (24a) to the one pivot bearing part (13b). In order to improve the guidance of the cage element (15), the first guide limb (19a) and / or the second guide limb (19b) has or have in each case a transversely aligned molding (25).

Description

technical field

[0001] The invention relates to an axial piston machine. Background technique

[0002] For axial piston machines of the swash plate type, it is known to form a swash plate on one of the two pivot bearing parts having a section curved into a circular arc on two opposite sides Shaped guide surfaces, between which there is a gap curved in the shape of a circular arc section, in which a cage segment with several rolling elements is supported. In this case, the axial piston machine is a variable-throughput swash plate whose swash plate can be rotated back and forth by adjustment means in the above-mentioned so-called carrier bearings. During this rotational movement in the circumferential direction of the curvature of the arcuate shape, the cage segments also move in the arcuate direction, wherein, due to the rolling function of the rolling elements, their travel length is substantially only half that of the rotational movement of the swash plate. During operati...
