Definitions

  • the present invention relates to a hydrostatic Radial piston machine.
  • Double flow according to the system of axial thrust compensation radial piston machines constructed for two rotors known; the rotors on these machines are non-rotatable on a wave. Basically are building on this Arrangement of both a hydrostatic pump and a hydrostatic motor can be displayed.
  • the object underlying the present invention is a hydrostatic radial piston machine specify the axial forces on the axis can be compensated.
  • the system should equally a hydrostatic pump with one or two Flow, a corresponding hydrostatic motor and a hydrostatic transmission can be represented.
  • Embodiments of hydrostatic Radial piston machines have a housing that has two, 5 interiors separated by an intermediate floor Has. These interiors are over on both sides a housing cover completed. In the respective two A stroke ring is stored in each of the subspaces (interior) both connected to each other via at least one bearing shaft are.
  • a hydrostatic radial piston machine with the features described above are from the after Priority date of the present application published EP-A-0 585 609 has become known.
  • hydrostatic radial piston machines can the conjugate cam rings 109, 208 using Adjusting pistons 131, 132, 231, 232 independently of one another be adjusted (see reference numbers 111, 211).
  • the drive or output of the machine is over Input and output shafts 2, 20 (Fig. 1, Fig. 7, Fig. 10) or 102, 202 (see Fig. 4) and via driver 41, 42 to a so-called Rotor 18, 19 forming cylindrical star.
  • the rotors 18, 19 have lateral control slots 21, 22, which with machined in axially arranged control disks 25, 26 kidney-shaped channels 23, 24 correspond.
  • the axial Sealing of these channels 23, 24 in the control disks 25, 26 takes place via elastic sealing elements 38, 39.
  • the known radial piston machines have an axis 43 on that fastened in the respective intermediate floor 5, 205, 305, 405 and at the ends of the rotors 18, 19 on the one hand between thrust washers 37, 44 and on the other hand the control discs 25, 26 are stored.
  • cam ring 8 9 (FIG. 1) or 109, 208 (FIGS. 4, 7, 10) are provided, both of which have a respective bearing shaft 10 Intermediate floor 5, 205, 305, 405 are stored.
  • the rotors 18, 19 are specific in terms of their Function as a pump or motor element as follows coordinated:
  • Control slots 21, 22 are provided through which the bores 16, 17 to the respective intermediate floor 5, 205, 305, 405 are open.
  • the control slots 21, 22 correspond in turn with those in the control discs (axial discs) 25, 26 incorporated kidney-shaped (compare Fig. 3, Fig. 6, Fig. 9, Fig. 11) channels 23, 24.
  • the control discs 25, 26 are in corresponding recesses on both Sides of the intermediate floor 5, 205, 305, 405 inserted.
  • the Intermediate floor 5, 205, 305, 405 itself are corresponding to said control slots 21, 22 and kidney-shaped Channels 23, 24 connecting channels 27, 28 (Fig.
  • the by the pressurization of the (displacement) pistons 15 and the control slots 21, 22 resulting axial thrust is due to the clamping of the axis 43 in the mezzanine 5, 205, 305, 405 between those supported on it Control disc 26 and a thrust washer 44 respectively which are supported on the intermediate floor 5, 205, 305, 405 Control disc 25 and a thrust washer 37 added and thus not on the housing cover 3, 4; 103, 204; 203, 304 transfer.
  • the two thrust washers 37, 44 are each biased against a collar 33, 34 on axis 43, that the distance between the thrust washers and the intermediate floor or the control disks 25, 26 is slightly larger than the width of the rotor 18, 19 corresponds.
