Definitions

  • the invention relates to a stator for a hydrodynamic torque converter according to the preamble of claim 1.
  • a stator for a hydrodynamic torque converter which is arranged axially between a pump wheel and a turbine wheel and has stator elements in the form of a stator hub with stator blades accommodated thereon, which are connected to one another radially on the outside by a stator ring.
  • the stator blades cause a fluid flowing from the turbine wheel to be fed to the pump wheel at a desired angle.
  • Such a stator can be manufactured in different ways. For reasons of cost, preference is given to an injection molding process for axially drawn molds, the latter having filling spaces into which material is introduced by means of the injection molding process. After this material has cooled, the casting tools are pulled apart axially, thereby releasing the stator.
  • Aluminum is usually used as the material for such an injection molding process, whereby the problem arises due to the thin liquid of this material in the heated state that material can escape at the contact zone of the two molds, which is noticeable as undesirable approaches on the stator blades.
  • a chisel is inserted in the axial direction between the respective flow outlet of a first stator blade and the flow inlet of a second stator blade.
  • thermoset powder is introduced into a mold and baked together under temperature and pressure to form an idler.
  • this has a smooth surface, the latter cannot be machined due to the required admixture of glass or carbon fibers, since cracks then form which would roughen this material on the tread if it came into contact with another material, such as steel. This would result in considerable wear.
  • thermoset guide vanes are preferably pulled radially. Although an optimal shape of the stator blades can be produced here, this manufacturing process is very expensive, since a number of tools corresponding to the number of stator blades must be removed radially outward after the thermoset powder has “caked”.
  • the object of the invention is to design a stator so that it has good efficiency and good identification while being inexpensive to manufacture and resistant to breakage.
  • stator element groups of the stator hub segments and the stator ring segments on the other hand, the dimensionally stable reception of the stator blades and the alignment of the latter in predeterminable planes should be of overriding importance, so that the stator hub segments as well as the stator ring segments after a connection has been established with one another must have sufficient strength.
  • the individual stator element groups can be isolated from each other on the circuit board by a separation process, the term "exemption" being used to emphasize that no complete separation of the individual stator element groups from one another is intended, but rather the separation process should be carried out to the extent that the stator element groups, which are still connected to one another at predetermined points, can be moved by deformation processes, for example in the form of a plastic deformation, from the original plane of the board to new, different planes of extension, so that the desired three-dimensional stator can ultimately emerge from the original two-dimensional board.
  • the deformation processes are not solely due to a change in the relative positions of the stator element groups to one another limited, but can also include a plastic deformation of the components of each stator element group.
  • stator element groups can also preferably be subjected to plastic deformation in order to align them, for example, along lines of curvature along which both the stator hub segments and the stator ring segments each extend around a central axis of the stator. Understandably, the curvature lines of stator hub segments and stator ring segments differ because of the different distances of the respective stator element group from said center axis.
  • stator segment hub By attaching the individual stator hub segments to each other, which can be the case, for example, by means of a welding process or by soldering or gluing to mutually facing butt ends, a stator segment hub is created that can be placed on a base body hub that acts as a carrier, so that both components come together , that is, the stator segment hub with the base body, are ultimately capable of forming the stator hub.
  • stator segment hub created in this way must of course on the Base body hub are fastened in such a way that no relative movements between the stator segment hub and base body hub are possible in both the axial and circumferential directions.
  • a fuse to be provided between the stator segment hub and base body hub, which is effective in the circumferential direction and / or in the axial direction and ensures that the stator wheel segment hub is connected to the base body hub without movement.
  • a profile groove can be formed on the base body hub, in which the formally adapted stator segment hub can be inserted.
  • the positive connection between the base body hub and the stator segment hub does not permit any movement in the circumferential and / or in the axial direction between these two components.
  • a fixed connection can only be added for safety reasons, for example in the form of individual weld spots between the base body hub and the stator segment hub, or by soldering or gluing, which can also be done in a punctiform manner.
  • stator rim segments can be joined to one another without additional connecting measures, in that a cover band is provided on the circuit board, on which, unlike the other parts of the stator element groups, the circuit board is not interrupted by separating processes.
  • the stator ring segments can thus, together with the shroud, receive the line of curvature that is required for the stator ring to enclose the central axis.
  • the blanks are made of a metallic material which, on the one hand, provides the required stability on the finished stator and, on the other hand, has good deformability, in order to be able to carry out the necessary deformation processes, preferably by cold forming, such as deep drawing or pressing.
  • cold forming such as deep drawing or pressing.
  • FIG. 1 shows a section of a torque converter in a sectional view, in which essentially the stator with different stator
  • FIG. 2 shows a circuit board for producing the stator after the different stator element groups have been exempted
  • FIG. 3 shows a detail from the circuit board in FIG. 2;
  • FIG. 4 shows a spatial representation of the stator after deformation processes on the circuit board of FIG. 2;

  • FIG. 9 shows a forming tool for producing the stator.
  • Fig. 10 is a sectional view along the section line IX-IX in Fig. 9;
  • Fig. 1 only the range of a hydrodynamic torque converter according to the invention is drawn out. It has been dispensed with to represent and describe the torque converter as a whole, because such torque converters are known from the prior art, for example from DE 41 21 586 A1.
  • the pump shell 1 shown in FIG. 1 serves to form a pump wheel 2, which cooperates with a turbine wheel 3, which is fixedly connected in the radially inner region to a turbine hub 4, which is connected via a toothing 5 to a drive shaft, not shown.
  • the pump shell 1 mentioned is fastened in the radially inner region to a pump hub 6 which extends in the direction of the output.
  • a guide wheel 7 is arranged axially between the pump wheel 2 and the turbine wheel 3 and is arranged via a first axial bearing 8 between the turbine hub 4 and a freewheel 9 and via a second axial bearing 10 between the freewheel 9 and the pump hub 6.
  • the two axial bearings 8 and 10 are each provided with a groove 11, 12 for hydraulic fluid, with which the converter circuit is supplied, in particular via the grooves 11 of the axial bearing 8.

  • the freewheel 9, on which the stator 7 is arranged, has a freewheel outer ring 23, which is guided via clamping bodies 25 on a freewheel inner ring 27, which is connected in a rotationally fixed manner via a toothing 29 to an output element, not shown, radially between this output element and the with the turbine hub 4 non-rotatable output shaft fluid for supplying the converter circuit via the groove 11 of the axial bearing 8 can be conducted.

  • the circuit board 32 is now transferred into another workpiece carrier 90, as can be seen from FIGS. 9 and 10 with regard to its basic structure.
