Embodiment Construction

[0028] figure 1 and figure 2 DE 10 2008 002 140 A1 of the same applicant is cited and used to illustrate the structural configuration and function of a hydrostatic module with a yoke 1 pivotable by means of an adjusting piston 6 , while Figure 3 to Figure 5 A different design according to the invention of the coupling device is shown in detail.

[0029] Depend on figure 1 It is evident that the hydrostatic module has a yoke 1 which is mounted rotatably about an axis of rotation 4 via a first mounting device 2 and a second mounting device 3 . Arranged in the yoke 1 are several inclined-axis drives as described in DE 10 2006 025 347 B3. Between the tilt-axis drive is a pivot lever 5 , which engages radially in the adjusting piston 6 . The adjusting piston 6 is accommodated in a bearing plate 7 which carries the bearing device 8 of the tilt-axis drive and is connected to the first bearing device 2 and the second bearing device 3 .

[0030] according to figure 2 , the yok...

Abstract

The adjusting device has an actuating cylinder provided with an actuating piston (21) that is aligned radially along rotational axis of a yoke portion. A pivot lever (16) is rigidly connected with the yoke portion. A coupling device is arranged at the actuating piston. A slide ring (20) is provided at an extending groove (25). A cylindrical pin (22) is located at an end portion (17) of the pivot lever or on the slide ring. The cylindrical pin is moved into a corresponding hole in the sliding ring or is connected in the end portion of the pivot lever.

Description

technical field [0001] The invention relates to an adjustment device for a hydrostatic module. Background technique [0002] Known construction types of hydrostatic axial-piston machines are inclined-shaft machines and inclined-disk machines. Such axial piston machines can be used as hydrostatic pumps or hydrostatic motors, respectively, with largely identical construction. In inclined-axis machines, the drive flange is rigidly connected to the associated drive shaft. The piston rods of a plurality of ejector pistons are articulated on the drive flange evenly distributed over the circumference. The ejector pistons are each arranged in one of a plurality of axial cylinder bores which are distributed in the cylinder respectively over the peripheral side. The cylinder is drive-connected, for example via an intermediate cardan shaft, to the drive shaft and is rotatably mounted in the yoke about its axis of rotation, by pivoting the yoke about a pivot axis running perpendicula...
