Embodiment Construction

[0040] FIG. 1 shows a prior art hydrostatic drive 1 , which is designed, for example, as a rotary drive.

[0041] The drive device 1 comprises a hydrostatic axial piston machine 2 of inclined-axis design, arranged in a housing 3 and designed as a hydraulic motor, which drives a downstream reduction gear 4 , The reduction gear is arranged in the gear housing 5 . In the exemplary embodiment shown, the transmission housing 5 is designed in two parts and is formed by an upper housing part 5 a and a lower housing part 5 b , which are flanged to one another. The housing 3 of the axial piston machine 2 is fastened to the transmission housing 5 by means of fastening flanges 6 and corresponding fastening screws 7 . The housing 3 of the axial piston machine comprises a housing cylinder 3 a and a housing cover 3 b flanged to the housing cylinder 3 a, on which the hydraulic connections of the axial piston machine 2 are formed. The oblique axial piston machine 2 and the downstream reduct...

Abstract

The invention relates to a hydrostatic axial piston engine (2) with inclined axes. The piston engine has: a driveshaft (104) rotatable in a housing (102) around an axis of rotation (Rt); a drive flange (3) rotatable inside the housing (102); and a cylinder barrel (107) rotatable around the axis of rotation (Rt) inside the housing (102) of the axial piston engine (2). The cylinder barrel (107) is provided with a plurality of piston spaces (108), and each piston (110) is longitudinally and movably arranged in the piston space. The pistons (110) are articulated and fixed on the drive flange (3). A support device (105) is arranged to drive support the drive flange (103) on the housing (102). According to the invention, the support device (105) of the drive flange (3) includes a radial bearing (105a) which receives a transverse force of the drive flange (103) and is raidally arranged between the drive flange (103) and a support seat (125) arranged on the housing (102).

Description

technical field [0001] The invention relates to a hydrostatic axial piston machine with oblique shaft structure, which comprises: a drive shaft rotatably arranged inside the casing around the rotation axis, a drive flange rotatably arranged inside the casing, A cylindrical drum rotatably arranged inside the housing of an axial-piston machine, wherein the cylindrical drum is provided with a plurality of piston cavities; each piston is longitudinally displaceable in these piston cavities; the pistons are articulated It is fixed on the driving flange; a supporting device is provided for supporting the driving flange in the housing. Background technique [0002] Axial piston machines of inclined-axis design according to the class can achieve high maximum permissible rotational speeds, so that axial-piston machines of inclined-axis design offer advantages for use as hydraulic motors. [0003] In hydrostatic axial piston machines of inclined-axis construction, the piston, which i...
