Definitions

  • the invention relates to an actuation device according to claim 1 , in particular an electronic actuator.
  • Claims 11 and 12 define an exhaust-gas turbocharger according to the invention as an independently marketable product.
  • Figure 1 shows a perspective illustration of an actuation device according to the invention
  • Figure 2 shows a detail illustration of a redirecting device
  • Figure 3 shows a front view of a shielding cap
  • Figure 4 shows a perspective illustration of the shielding cap as per figure
  • Figure 5 shows a perspective sectional illustration of a known exhaust-gas turbocharger having an actuator which can be replaced with the actuation device as per figure 1 in order to convert the exhaust-gas turbocharger into a turbocharger according to invention.
  • Figure 1 illustrates an actuation device 1 according to the invention which, in the example, is in the form of an electronic actuator (electric actuator).
  • the electric actuator 1 has a housing 2 in which an actuation shank (not visible in its entirety) is guided by way of a first shank portion.
  • the actuation shank has a second shank portion 3 which projects out of the housing 2 and which is indicated by dashed lines in figure 1.
  • said second shank portion 3 is surrounded by a shielding cap 4 which is fastened, in particular screwed, to the housing 2.
  • the second shank portion 3 is, aside from a fastening region 5, covered by the shielding cap 4 in order to prevent an undesired introduction of heat into the shank portion 3.
  • the shielding cap 4 has two interconnected first and second cylinder portions 6 and 7.
  • the cylinder portion 6 has a diameter Di which is smaller than the diameter D 2 of the cylinder portion 7.
  • the cylinder portions 6 and 7 are connected to one another via a rounded transition region 19, wherein the shielding cap 4 is preferably a unipartite component.
  • the shielding cap 4 has cooling and water outlet bores 8, 9, 10 and 11.
  • a twist prevention means 12 which is in the form of a recess in the second cylinder portion 7.
  • Said recess 12 has a rectangular recess region 12A and, adjoining the latter and adjacent to the first cylinder portion 6, a conically narrowing recess region 12B.
  • the recess 12 adjoins an end-side opening 14 of the second cylinder portion 7, said opening being arranged opposite a passage recess 18 of the first cylinder portion 6, through which passage recess the shank portion 3 extends when the shielding cap 4 is in the mounted state, as can be seen in figure 1.
  • the shielding cap 4 also has a flanged portion 13 which encircles the end-side opening 14 of the second cylinder portion 7. Said flanged portion 13 is provided with recesses, of which the recesses 15, 16 and 17 are visible in figure 4. Said recesses serve for the passage of screws by which the shielding cap 4 can be fastened to the housing 2 of the actuation device 1. In principle, however, other fastening facilities are also conceivable.
  • Figures 1 and 2 also show that the actuation device 1 according to the invention is provided with a redirecting device 20.
  • Said redirecting device 20 is fixed to the fastening region 5 of the shank portion 3, for which purpose, in the example, the fastening region 5 is provided with an external thread which is not shown in detail in figure 1.
  • connection plate 23 is arranged on one end side 22 of a central part 21 of the redirecting device 20. As shown in figure 2, in the particularly preferred embodiment illustrated therein, a right angle a is enclosed between the central part 21 and the connection plate 23.
  • the redirecting device 20 has a journal plate 24 which is arranged on a longitudinal side of the central part 21. From this, it can be seen that the plane of the connection plate 23 is rotated through 90° with respect to the plane of the journal plate 24, as can be seen in detail from the illustration of figure 2. On the journal plate 24 there is arranged a journal 25 which is preferably of spherical form.
  • the journal 25 extends through a connection eyelet of one end of a coupling rod 26 in order to connect the coupling rod 26 to the actuation shank of the electric actuator 1.
  • the eyelet through which the journal 25 extends corresponds to an eyelet 29 arranged on the other end of the coupling rod 26, as can be seen in detail from the illustration of figure 1.
  • connection plate 23 to an end side 22 of the central part 21 and the arrangement, turned through 90°, of the journal plate 24 on a longitudinal side of the central part 21, a configuration of the redirecting device 20 is attained which permits a redirection of kinematic planes.
  • the journal 25 may, owing to its construction, be formed as a precision casting or bent sheet-metal part or else as an MIM part.
  • Figure 5 illustrates, as an example of a known exhaust-gas turbocharger, the turbocharger 30 which has an actuator 44 with a control rod 43.
  • Said design represents a known embodiment.
  • the exhaust-gas turbocharger 30 may however be converted into an exhaust-gas turbocharger according to the invention if the actuator 44 with its control rod 43 is exchanged for the actuation device 1 according to invention explained above in conjunction with figures 1 to 4.
