Definitions
- the invention relates to an adjusting device for a charging device, in particular for an exhaust gas turbocharger, the specified in the preamble of claim 1.
- Fixing portion is connected, and a socket which is arranged on a base body of the adjusting shaft. Furthermore, a seal is provided, which is arranged in the region of the base body between the bushing and the adjusting shaft, wherein the base body of the adjusting shaft has a stepped outer contour, and the bushing has an inner contour which is complementary to form the base body.
- the sealing of the adjusting shaft assembly by the seal which is arranged between the adjusting shaft and the bush, has the disadvantage that the adjusting shaft has a groove corresponding to the seal, resulting in a weakening of the
- Adjusting shaft means This is problematic in that the adjusting shaft is exposed to high temperatures, which due to the weakening of the shaft through the groove leads to an increased probability of failure of the adjusting shaft and the adjusting arrangement.
- the seal is extremely cumbersome and therefore time and
- Another problem is the fact that a seal between the sleeve and a housing in which the socket is to be accommodated is not possible, resulting in undesirable gas leakage. It is therefore an object of the present invention to provide an adjusting device for a charging device, in particular for an exhaust gas turbocharger, which has an improved seal.
- An adjusting device for a charging device, in particular an exhaust gas turbocharger, with a bearing element, in particular a bush in which at least partially an adjusting is at least partially accommodated and by means of which the adjusting is storable in a housing of the charging device, characterized in that on the Adjusting shaft is arranged in a bearing element in the axial direction superior portion of the adjusting shaft at least one sealing element.
- the arrangement of the sealing element on the said region holds the possibility that a sealing of the adjusting device is made possible directly in the radial direction of the adjusting between this and the said housing, which thus not only a gas leakage between the adjusting and the bearing element but also in particular between the Adjusting shaft and the housing is avoided.
- the sealing element is thus arranged in a region of the adjusting shaft which, as described, projects beyond the bearing element in the axial direction and is also covered by the housing in which the adjusting shaft is to be supported via the bearing element, so that a sealing contact between the arranged on the control shaft seal member and the housing is made possible.
- the adjusting device according to the invention further has the advantage that an assembly or arrangement of the sealing element can be done easily and thus quickly and inexpensively, which is extremely beneficial to the low total cost of the adjusting device.
- the adjusting shaft in the said region on a collar that is, a projection extending in the radial direction of the adjusting projection, on which the sealing element is arranged.
- Such a receptacle for example in the form of a groove, can now be provided in the radial direction of the adjusting shaft on the collar in order to ensure a secure fit of the
- Seal member which is for example in the form of a sealing ring, too
- Adjustment device since by avoiding the weakening of the shaft, this can withstand high loads and in particular also high temperatures over a long period of operation and lifetime.
- housing is advantageously provided that the sealing element covers the collar in the radial direction of the adjusting shaft at least partially, which
- the sealing element is realized for example by a substantially L-shaped configuration of the sealing element, which thus engages, for example, with a leg of the L-shape in its corresponding groove and covered with the other leg of the L-shape the federal government in the radial direction of the adjusting.
- Adjusting device against a gas leak so against leakage of exhaust gas, for example, from a turbine of the charging device benefits.
- the adjustment device according to the invention is used, for example, in connection with a charging device, in particular an exhaust gas turbocharger, wherein by means of the adjusting device, for example a valve device, in particular a wastegate and / or adjustable guide vanes, in particular a variable turbine geometry, the charging device is or are operable.
- a charging device in particular an exhaust gas turbocharger
- the adjusting device for example a valve device, in particular a wastegate and / or adjustable guide vanes, in particular a variable turbine geometry, the charging device is or are operable.
- FIG. 1 shows a detail of a longitudinal sectional view of an embodiment of the adjusting device according to the invention and accommodated in a housing of a charging device; a detail of an enlarged view of a portion of the adjusting device of FIG. 1; Fig. 3 is a perspective view of the adjusting device according to the
- Fig. 4 is a plan view of the adjusting device according to the preceding
- Fig. 1 shows an adjusting device 10 for a housing 12 having
- Charging device in the form of an exhaust gas turbocharger, wherein the housing 12 as
- Turbine housing is formed, through which a turbine of a turbine of the exhaust gas turbocharger is received.
- the adjusting device 10 comprises a bearing element in the form of a bush 14, in which an adjusting shaft 16 of the adjusting device 10 is received.
- the adjusting shaft 16 is rotatably mounted in the housing 12 by means of the bushing 14 about an axis of rotation 18.
- the adjusting shaft 14 has a sleeve 14 in the axial direction according to a
- Directional arrow 20 of the adjusting shaft 18 projecting portion 22, in which a collar 24 of the adjusting shaft 14 is arranged.
- the collar 24 in turn has a groove 26 in which a corresponding
- Seal element is arranged in the form of a sealing ring 28, wherein the sealing ring 28 is thus arranged on the collar 24 of the adjusting shaft 18.
- this creates a direct seal between the housing 12 and the adjusting shaft 14, whereby a leakage and thus an outlet of the exhaust gas flowing through the turbine between the sleeve 14 and the housing and / or between the adjusting shaft 16 and the sleeve 14th through to the environment.
- the adjusting shaft 16 is not constricted and thus weakened by this shown in FIG. 1 arrangement of the sealing ring 28 on the collar 24 in the region 22 of the adjusting 16, whereby they high loads, especially high
- the adjusting shaft 14 further comprises an actuating part 30, via which, for example, a valve device, in particular a wastegate, the turbine can be actuated.
- the sealing ring 28 is substantially L-shaped
- the axial extent s of the sealing ring 28 is for example 2 mm.
- Fig. 3 shows the adjusting device 10, wherein the adjusting shaft 14 is on the one hand connected to an actuating lever 34, which in turn is actuated by means of an actuator, whereby a rotation of the adjusting shaft 14 about the axis of rotation 18 can be performed.
- valve device 36 which is connected to the actuating part 30.
- a rotation of the adjusting shaft 14 by an actuation of the actuating lever 34 leads to an opening or closing of the valve device 36, whereby, for example, a
- Boost pressure of said exhaust gas turbocharger is limited.
