  • Patent number: 4858480
    Abstract: The invention relates to a swash plate swivel bearing for a hydraulic axial piston machine, in which roller-bearing segments are arranged between the hollow cylindrical bearing surface for the swash plate in the housing and the cylindrical bearing surface on the swash plate, which segments are held in curved cages with each of which is associated a tracker having a tracking mechanism guided by a guide member in a first guide, which mechanism is in drive connection with a carrier of the cage. It is the object of the invention to design a swash plate swivel bearing of the construction indicated above so that the guide member can cooperate directly with the carrier of the cage.

  • Patent number: 4771677
    Abstract: The invention relates to an axial piston machine having an oblique disk body (14) arranged in a housing (1) in a torsionally secure manner, having a drive shaft (4), which is mounted in the oblique disk body (14), and having a rotatable cylinder drum (7), which is coupled with the drive shaft (4) and in which a plurality of pistons (9) may be displaced axially in piston bore holes, their piston heads (11) being supported by means of sliding shoes (12) against the oblique surface (13) of the oblique disk body (14). The purpose of the invention is to construct the axial piston machine in such a way as to make possible torsional securement of the oblique disk body (14) which is simple in terms of production techniques and assembly, with a compact constructional form. This is achieved by mounting the oblique disk body (14) with its peripheral surface (16, 17) torsionally secured in a form-locking manner in a recess (19) of the housing (1) shaped to correspond to the peripheral surface (16, 17).
