Definitions
- the present invention relates to a housing for a component of a
- Exhaust system having a first and a second half-shell, which are connected to each other at least in sections by means of an edge portion, and with at least one opening for a pipe to be connected to the housing.
- Such housings are in practical use and are used for different components of the exhaust system, for example for catalysts, diesel particulate filters and in particular for silencers.
- Figure 1 shows an example of a muffler 1 with a housing 10 of the type mentioned in the prior art.
- the housing 10 includes a first half-shell 12 and an overlying second half-shell, which is not shown in the figure. hn inside the housing 10, an inner tube 14 is arranged, which is surrounded in some applications by an insulating mat 16 and in which an exhaust-carrying pipe can be partially introduced. The connection of the exhaust-carrying pipe to the housing 10 via an opening 18 which is disposed in the housing 10 in the region of a front side S.
- the two half shells have two longitudinal edge portions 20, e.g. are connected by crimping or welding together.
- connection of the two half shells is performed by machine along the longitudinal edges of the two edge portions 20.
- the edge portions 20 have over their entire length a substantially uniform width of about 8 to 10 mm (in
- a disadvantage of the described housing 10 according to the prior art is that the housing 10 in the region of the opening 18 in the horizontal direction (ie along the edge portions 20) has a significantly greater rigidity as in the vertical direction (perpendicular to the plane of the edge portions 20). This results in a jump in stiffness in this area, which leads to a limited fatigue strength under bending stress and thus to a shortened durability of the housing.
- the object of the present invention is therefore to provide a housing for a component of an exhaust system, are avoided in the stiffness jumps in the region of an opening which serves to attach an exhaust pipe, and which is also easy to produce.
- the edge portions expire at the opening and the width of the edge portions is reduced to the opening.
- the stiffness in the horizontal direction can be significantly reduced and thus approach the stiffness in the vertical direction.
- an increase in the fatigue strength of the housing in the region of the opening by about 30 percent and thus a significantly improved durability is achieved, which is comparable to the durability of a housing having an additional bracing in the region of the opening.
- the embodiment according to the invention usually eliminates the need for manual rewelding.
- the width of the edge sections in the area of the opening can be about half the normal width of the edge sections, advantageously about one third of the normal width.
- At least one tube is preferably attached to the housing, which is welded to the housing by means of a weld seam, wherein the width of the edge sections in the region of the opening is at most equal to the height of the weld seam.
- the half-shells are thus connected to one another at the front end of the housing exclusively by the weld seam required anyway for attaching the exhaust-gas-carrying pipe, whereby a complete closing of the housing is realized in a simple, cost-effective and time-saving manner.
- the housing according to the invention is less susceptible to cracking in the region of the weld.
- a particularly favorable ratio of horizontal to vertical rigidity which leads to an optimal fatigue strength of the housing in the region of the opening, results when the edge portions with the central axis of the tube form an angle of about 30 °.
- FIG. 2 shows a erfmdungsconcees housing 10 of a muffler 1, which replaces the housing 10 shown in Figure 1 according to the prior art.
- corresponding components carry the same reference numerals, and it will be discussed below only on the differences of the housing 10 according to the invention to the prior art.
- the edge portions 20 at the housing 18 run out at the opening 18, and the width of the edge portions 20 is reduced towards the opening 18.
- the width of the edge portions 20 is selected in this area so that it is on the front side S about half, better one third of the normal width of the edge portions, that is about 2 to 4 mm.
- FIG. 3 Another advantage of the housing 10 according to the invention will become apparent when a waste gas-carrying tube 22 is attached to the housing 10 and welded to the housing 10 by means of a weld 24 (FIG. 3).
- the weld 24 has, as well as the opening 18, substantially the shape of the pipe cross-section. Due to the reduced width of the edge portions 20 in the region of the opening 18, in which the tube 22 is introduced, can be with the weld 24 at the same time the entire frontal areas X both edge portions 20 close, without it being necessary, the housing 10 in its end face area S to be welded separately.
- An optimal fatigue strength of the housing 10 can be achieved in that the edge portions 20 in the region of the opening 18 with the central axis of the tube 22 form an angle ⁇ of about 30 °.
- FIG. 5 shows a second embodiment of the housing 30 according to the invention, which provides two separate flow paths 32 and is used, for example, as the housing of a middle silencer.
- the housing 30 also consists of a first half shell (not shown) and an overlying second half shell 34, the longitudinal edge portions 36 of which, as already described with reference to FIGS. 1 to 3, are connected to one another.
