Definitions
- the invention relates to a housing for a component of an exhaust system, in particular for an exhaust gas purification device.
- the invention also relates to a method for producing a housing for a component of an exhaust system.
- the component may in particular be a diesel particulate filter or a catalyst. These are mounted together with a bearing mat inside the housing.
- a manufacturing process which is commonly referred to as “calibration,” is frequently used, providing the housing with a circumferentially closed shell, then inserting the component with the bearing mat into the shell, and then the shell in the radial direction until the component with the bearing mat is held at the desired pressure inside the housing, this process is also known as “shrinking.”
- shrink method while the jacket is individually geshrinkt each, so taking into account the individual dimensions of the component and the bearing mat. This causes the diameter of the geshrinkten housing varies within certain limits.
- an inlet cone and an outlet cone is attached. Since these are always provided with the same diameter, it is provided in modern shrink method to calibrate the axial ends of the housing for the component after shrinking, so that the housing always has the same diameter at least at its axial ends, regardless of individual Shrink. This process is very complicated on the whole.
- the object of the invention is to provide a housing for a component of an exhaust system, which makes it possible with less effort
- the object of the invention It is also to provide a method for facilitating the manufacture of such a housing.
- a housing for a component of an exhaust system is provided according to the invention, in particular for an exhaust gas purification device, with a jacket having a geshrinkten clamping portion for the component and a transition portion which connects in the axial direction of the clamping portion, and a connecting portion, the adjoins the transition section in the axial direction and has a larger diameter than the clamping section.
- the following steps are provided: First, a tubular jacket is provided. Then the component is introduced into the jacket together with the bearing mat. Subsequently, the jacket is shrunk in a clamping portion which, viewed in the axial direction, terminates at a distance from the ends of the jacket, while the axial ends of the jacket are not acted upon.
- the invention is based on the surprising finding that when the shell is only shrunk in a central region and a short section remains unprocessed at the axial ends of the shell, the diameter and also the angle of these unprocessed sections to only a very small extent from the diameter of the depends on the central area.
- the diameter to which the central region is shrunk always results in an approximately frusto-conical connecting portion at the axial ends of the shell whose diameter and angular orientation varies only to such a small extent that it without further processing steps for connecting the inlet cone or the outlet cone is suitable.
- the jacket when the component is accommodated in the interior of the housing, the jacket ends approximately flush with the component in the axial direction.
- the invention takes into account the recognition that the diameter of the shell at the axial ends, when the clamping portion is shrunk, increases, so that there is sufficient space for receiving the input cone or the output cone available. This is insofar Surprisingly, when the diameter at the axial end of the shell changes in exactly the opposite direction as the diameter of the clamping portion.
- FIG. 1 a schematic section through a housing according to the invention
- FIG. 3 shows schematically the shape of the shell before and after shrinking.
- a housing 10 can be seen, which consists of a jacket 12 and two connecting parts 14, of which only one is shown here.
- the connecting parts are an inlet cone or an outlet cone, with which the housing can be connected to an exhaust system of an internal combustion engine.
- a component 16 of the exhaust system is arranged, in particular a diesel particulate filter or a catalyst.
- the component 16 is surrounded by a bearing mat 18.
- the shell 12 has a diameter DA (see Figure 3), wherein the jacket does not necessarily have to have a circular cross-section, but also may have an oval, triovalen or other cross-section.
- DA diameter
- a cross-sectionally curved transition portion 24 in which the diameter of the shell widens outwardly, and the transition portion 24 is followed by a connecting portion 26 which is approximately frusto-conical and its maximum diameter at axial end of the shell 12 has.
- the connecting portion 26 has an inclination angle of ⁇ , and the diameter of the shell at the outer end of the connecting portion 26th is larger than the output diameter DA.
- the total length of the jacket increases when shrinking, since the reduction in diameter of the shell precipitates about half in a larger wall thickness and the other half in a greater length. In modern shrink method, the final diameter DE is at the respective
- Diameter of the component 16 tuned. It is noteworthy, however, that changes in the final diameter DE lead only to a negligible extent to changes in the diameter of the connecting portion 26 and the angle ⁇ . In experiments it has been found that in shrinking, for example, from a starting diameter of 158.4 mm to a nominal diameter of 152.8 mm and an individual adjustment of the final diameter DE by + 1 mm from the nominal diameter, a negligible change in the diameter of the connecting portion in the range of ⁇ 0 , 1 mm could be observed. The length L, with which the jacket protrudes beyond the shrinking tool 22 in the initial state, was varied between 15 and 24 mm.
- a standard connection part 14 can be attached to each individually jacketed jacket 12. This can, for example, as can be seen in Figures 1 and 2, have a tapered connecting portion 15 which is inserted into the connecting portion 26. Subsequently, the jacket 12 and the connector 14 can be connected together, e.g. welded or soldered.
