Definitions
- the present invention relates to a silencer for a gas and airborne sounding conduit, in particular for an exhaust system of an internal combustion engine, preferably in a motor vehicle.
- a silencer of the type mentioned in the introduction.
- the muffler is flowed through by the gas transported in the line.
- the entrained airborne sound enters the muffler with the gas and is attenuated therein, for example by means of reflections, resonances and sound-absorbing materials.
- the gas then flows out of the muffler at a reduced airborne sound level.
- Such mufflers are preferably used in exhaust systems of the internal combustion engine, in particular in motor vehicles, in order to dampen the sound generated by the internal combustion engine which propagates through the exhaust system.
- a muffler for example, to dampen the sound generated by a compressor of an exhaust gas turbocharger.
- the attenuation of airborne sound may also be of interest in other gas-carrying lines, so that the present invention should in principle not be restricted to applications in internal combustion engines.
- such inner floors are used to fix the inner tubes in the housing. It is customary in the vicinity of the sliding seat to attach the one inner tube to a first inner bottom and to attach the other inner tube to a second inner bottom, which is spaced from the first inner bottom.
- the two inner floors are then on both sides arranged the sliding seat.
- the two inner floors have only a comparatively small distance from each other, the housing has a particularly high rigidity in this area.
- the introduction of such an inner bottom at least for series products associated with relatively high costs. In addition, this increases the weight of the muffler.
- the present invention is concerned with the problem of providing for a muffler of the type mentioned an improved embodiment, which is characterized in particular by a reduced weight and a low-cost structure.
- the invention is based on the general idea to attach both inner tubes to one and the same inner bottom and to form at this inner bottom at least one attached to the one inner tube resilient first tongue and at least one attached to the other inner tube, resilient second tongue, which is independent of the at least a first tongue is resiliently movable. Due to this design, the resilient tongues can thermally Conditional changes in length of the inner tubes follow independently, without causing unacceptably high stresses within the inner bottom.
- a particular advantage of the present invention is that a complete inner bottom can be omitted, which brings a great cost saving and weight reduction.
- the invention uses the knowledge that in the physicallysteifenden area of the housing sufficient stiffening can be achieved with a single inner bottom, so that a second inner bottom is not required, at least in terms of stiffening of the housing in this housing section. It is also important for the invention that both inner tubes are supported in the region of the sliding seat independently of each other via the one common inner bottom of the housing, resulting in a stable and positionally fixed positioning for both inner tubes in the housing.
- the tongues may be formed by free cutting or free punching on the inner bottom.
- the tongues can be made particularly simple and inexpensive.
- the tongues are integrated into the inner floor or form an integral component with the inner bottom. This integral construction has the advantage that no separately produced tongues need to be attached to the inner bottom with additional work.
- the inner tubes may be radially spaced apart in the sliding seat region. That is, the inner tubes have in the Sliding seat radial play and do not touch. Such a sliding seat is inevitably leaking, but this is harmless depending on the flow in the silencer. It is advantageous in this non-contact sliding seat that in particular a tension of the two inner tubes can be avoided in the sliding seat due to thermally induced radial expansions, so that the axial mobility of the two inner tubes is guaranteed in the sliding seat accordingly.
- a silencer 1 according to the invention comprises a housing 2, in which at least one inner bottom 3 and at least two inner tubes, namely a first inner tube 4 and a second inner tube 5, are arranged.
- the silencer 1 is here without restriction of the generality as a silencer 1 for an exhaust system of an internal combustion engine, preferably in a motor vehicle, designed. In principle, however, the silencer 1 can be provided for any other gas and airborne sounding line.
- the inner bottom 3 is used to stiffen the housing 2. It is clear that the housing 2 can in principle also be equipped with more than one inner bottom 3.
- the inner tubes 4, 5 serve to guide gas in the interior of the housing 2, that is to say in particular for the exhaust gas routing. This means that the muffler 1 at least within its inner tubes 4, 5 of the Airborne transporting gas is flowed through. It is also clear here that the muffler 1 can basically have more than two inner tubes.
- the muffler 1 can be configured in the usual way as an absorption muffler and accordingly contain absorption materials. Furthermore, the silencer 1 can work with resonance effects and / or with reflections in order to dampen the airborne sound entrained in the gas.
- the two inner tubes 4, 5 are inserted axially into one another in a sliding seat region 6 characterized by a brace, such that they are axially movable relative to one another.
- the inner tubes 4, 5 in the sliding seat region 6 radial play 7, that is, the two inner tubes 4, 5 are radially spaced from each other in the sliding seat portion 6.
- the two inner tubes 4, 5 pass through the inner bottom 3 in the sliding seat region 6. Furthermore, both inner tubes 4, 5 are each fastened to this one common inner bottom 3.
- the inner bottom 3 according to FIGS. 1 and 2 at least a first tongue 8.
- two first tongues 8 are provided, which are diametrically opposed.
- the first tongues 8 are resilient and in each case in the sliding seat region 6 fixedly connected to the first inner tube 4.
- the first tongues 8 are soldered or welded to the outside of the first inner tube 4.
- the inner bottom 3 also has at least one second tongue 9.
- two second tongues 9 are provided, which are diametrically opposite.
- the first tongues 8 and the second tongues 9 are aligned perpendicular to each other, that is, offset by 90 ° to each other.
- the second tongues 9 are fixedly connected to the second inner tube 5 and also designed resiliently. It is essential that the second tongues 9 are resiliently movable substantially independently of the first tongues 8. This can be done by a corresponding configuration, in particular with regard to positioning, shaping and dimensioning.
- the first inner tube 4 can expand axially.
- This axial movement of the first inner tube 4 is not critical with respect to the second inner tube 5, since the sliding seat region 6 permits an axial adjustment of the two inner tubes 4, 5 relative to one another.
- the axial adjustment of the first inner tube 4 is likewise not critical, since the first tongues 8 can elastically follow the axial movement of the first inner tube 4 due to their spring elasticity.
- the spring elasticity of the relatively short first tongues 8 is realized here by the elasticity of the inner bottom 3, on which the first tongues 8 are arranged or formed. The inner bottom 3 is thereby bumped reversible.
- the length of the second inner tube 5 may also change. Due to the axial mobility relative to the first inner tube 4 in the sliding seat region 6, no tension with the first inner tube 4 can arise. With regard to the inner bottom 3, the changes in length of the second inner tube 5 are also not critical, since the second tongues 9 can follow this axial movements of the second inner tube 5 elastically due to their spring elasticity.
- the spring elasticity of the second tongues 9 is realized here by a comparatively large length of the second tongues 9. In that regard, it comes with an elastic bending of the second tongues 9 is not or only slightly to a bending of the inner bottom 2. In this way disturbing interactions in the elastic yielding of the tongues 8, 9 can be avoided. In that regard, the tongues 8 and 9 are independent of each other resiliently movable.
- At least the first tongues 8 or at least the second tongues 8, but preferably all the tongues 8, 9 are integrally formed on the inner bottom 3. This is achieved, for example, by free cutting or free punching of the tongues 8, 9 on the inner bottom 3. Alternatively, it would in principle be possible to produce the first tongues 8 and / or the second tongues 9 separately from the inner bottom 3 and then fasten them to the inner bottom 3.
- the inner bottom 3 extends substantially in a first plane 10.
- the arrangement of the first tongues 8 is expedient here so that they also extend in the first plane 10.
- the first tongues 8 are also secured at their free ends 11 substantially in the first plane 10 on the first inner tube 4.
- the fixing of the first tongues 8 takes place at a free end 12 of the first inner tube 4, that is to say in the sliding seat region 6.
- the first tongues 8 are thus elastically movable perpendicular to the first plane 10.
- the second tongues 9 are fastened at their free ends 13 in a second plane 14, which is at a distance from the first plane 10 and runs parallel thereto, on the second inner tube 5.
- the fixing of the second tongues 9 on the second inner tube 5 likewise takes place in the region of a free end 15 of the second inner tube 5, ie in the sliding seat region 6.
- the second tongues 9 each have a substantially rectilinear section 16 which defines the respective free end 13 and extends substantially in the second plane 14.
- the second tongues 9 are each provided with an angled portion 17, which is angled at one end to the rectilinear portion 16 and the other end is angled from the inner bottom 3. Accordingly, the second tongues 9 are angled at their fixed ends 18 from the inner bottom 3.
- the second tongues 9 are thus movable elastically perpendicular to the second plane 14.
- Essential for the connection of the tongues 8, 9 to the inner tubes 4, 5 is that the axial mobility of the two inner tubes 4, 5 in the sliding seat area 6 is not hindered by these connections.
- the two planes 10 and 14 which are parallel to each other, spaced from each other.
