Problems solved by technology

Although the axial piston pump has an inexpensive adjustment mechanism here, some functions seem to have disadvantages, such as the limited force level of the adjustment and the limited adjustment of the swash plate due to the zero position. Continuous rotatability

Embodiment Construction

[0024] Here first, according to the figure 1 Examples are described. In the following, mainly only the differences between the second exemplary embodiment and the first exemplary embodiment will be discussed.

[0025] according to figure 1 The hydrostatic axial piston machine of is designed to be operated as a pump or as a motor. The axial piston machine has a two-part housing 10 with a housing pot 11 and a web 12 closing the housing pot on its open side, on which is not shown in detail The pressure joint and the storage tank joint are constructed in the same way. From the pressure connection and from the tank connection, channels, which cannot be seen in detail, lead in each case and merge into kidney-shaped openings on the inner side of the connecting plate 12 .

[0026] The axial piston machine has a drive shaft 15 which passes through a first tapered roller bearing 16 inserted into the bottom 17 of the housing pot 11 and a second, not shown, received by the connecting ...

Abstract

The invention relates to a hydrostatic axial piston machine with a swash plate structure, in order to make the adjusting device easy and low-cost to manufacture and require less structural space, the joint between the adjusting piston and the swash plate is a movable rotary joint, the rotary joint comprises a joint body receiving part on one of the two parts of the adjusting piston and the swash plate and a joint body on the other one of the two parts of the piston and the swash plate. The joint body is guided in the direction of the movement direction of the adjusting piston in the joint body receiving part in a clinging manner, can rotate around a rotation axis extending parallel to the rotation axis, and can move with a direction component perpendicular to the movement direction of the adjusting piston and perpendicular to the rotation axis.

Description

technical field [0001] The invention relates to a hydrostatic axial piston machine with a swash plate structure, in particular to an axial piston pump. The axial piston machine has a housing; a drive shaft rotatably mounted in the housing; a cylinder with a displacement piston connected to the drive shaft in a rotationally fixed manner; A swash plate with a working surface supported in the body, on which the displacement piston is supported and whose angular position relative to the axis of rotation of the drive shaft and the cylinder barrel can be adjusted for displacement by the The deflection of the swash plate around the axis of rotation is changed. For deflecting the swash plate, there is an adjusting device having an adjusting cylinder and a double-acting adjusting piston displaceable longitudinally in the adjusting cylinder, wherein the adjusting cylinder is substantially along the drive shaft The direction of the axis of rotation extends longitudinally and is on one ...
