Description

Sealing device for exhaust gas cooler
The present invention relates to a sealing arrangement for an exhaust gas cooler according to the preamble of claim 1.
The planar seal is clamped between the planar connecting element and the planar sealing element, so that the air-conducting connection point between the connecting element and the sealing element of the exhaust gas cooler is sealed. The seal substantially conforms to the contour of the connecting element and the sealing element such that a gas passage between the connecting element and the sealing element and a threaded opening for securing the connecting element to the sealing element remain open. Undesired leakage caused by displacement of the seal relative to the connecting element or relative to the sealing element should be avoided.
In the prior art, some solutions to this problem are known. On the one hand, it is intended to achieve a better sealing of the connection point by adjusting the seal, as proposed, for example, in DE 102006020838 a1 and DE 102012112135 a 1. However, such seals are complicated in production and therefore expensive.
On the other hand, it is intended to fix the seal more precisely on the connecting element and thus on the sealing element, as described for example in DE 20105250U 1 and WO 2008/074500 a 1. In this case, a seal is proposed in each case with a projecting spring element which engages in a force-fitting manner in a threaded opening of the connecting element and in this way fixes the seal at least temporarily to the connecting element. However, during transport and installation of the sealing element, the seal can easily fall off the connecting element and damage the connecting element. In addition, the elements engaged in the threaded openings also make it difficult to fix the connecting element to the sealing element.
It is therefore an object of the present invention to provide a sealing arrangement for an exhaust gas cooler, with which the above-mentioned disadvantages are overcome.
According to the invention, this object is solved by the subject matter of independent claim 1. Advantageous embodiments are the subject of the dependent claims.
A sealing arrangement for an exhaust gas cooler comprises a plate-shaped connecting body and a surface seal which abuts against a sealing surface of the connecting body. The connecting body comprises an air guide channel extending through the connecting body, which corresponds to the air guide opening in the face seal. In addition, the connecting body comprises at least two fixing holes, which correspond to the respective fixing openings of the surface seal. The surface seals each comprise, on the respective fixing opening, a clamping device integrally formed on the surface seal, which clamping device engages in a respective fixing hole of the connecting body. According to the invention, each fixing hole has a first positive-locking contour on the inner circumference and each clamping device has a second positive-locking contour, the first and second positive-locking contours forming a positive lock.
The surface seal is positively fixed on the connecting body against the sealing surface by means of a positive fit between a first positive fit contour in a corresponding fixing hole of the connecting body and a second positive fit contour on a corresponding clamping device of the surface seal. By means of the form fit, the face seal is axially fixed on the longitudinal axis of the respective fixing hole, so that a displacement of the face seal perpendicular to the sealing surface and thus a separation of the face seal from the connecting body is avoided. By fixing the surface seal in a form-fitting manner on the at least two fixing openings, the surface seal is also fixed on the sealing surface in a manner that is radial to the respective longitudinal axis and immovable. Furthermore, a twisting of the surface seal on the connecting body relative to the respective longitudinal axis is thus also avoided. Advantageously, in the sealing arrangement according to the invention, both an undesired detachment of the face seal from the connecting body and an undesired displacement or distortion of the face seal on the sealing surface can be avoided. The transport and installation of the sealing device is thus considerably simplified and, in addition, a secure seal can be achieved.
In a further advantageous development of the solution according to the invention, the first positive-fit contour is formed by at least one stepped recess in the respective fixing bore facing away from the sealing surface, and the clamping device is formed by at least one tab which engages at least partially with the stepped recess and has the second positive-fit contour. The at least one stepped recess and the at least one web advantageously form a positive fit, so that the surface seal is fixed to the connecting body axially to the longitudinal axis of the respective fixing bore. On the at least one stepped recess, single and multiple tabs can be arranged in a form-fitting manner. At least one stepped recess extends axially in the fixing hole and at least one tab is disposed entirely within the fixing hole. In this way, the risk of the tab being damaged during installation of the sealing device is reduced and, in addition, installation of the sealing device is simplified.
Advantageously, the inner circumference of each fixing hole is formed partly by the circular hole circumference and partly by at least one stepped recess, wherein the respective stepped recess and the respective tab are located radially outside the hole circumference. The circular bore may then comprise, for example, an internal thread, which may engage with an external thread of the screw. The at least one stepped recess and the at least one web are located radially outside the circumference of the circular bore, so that the connection of the internal thread of the respective fixing bore to the external thread of the screw can take place over the entire length of the respective fixing bore. In this way, the connecting body can be firmly fixed to the exhaust gas cooler and the sealing of the exhaust gas cooler can be significantly improved. In such an embodiment, the face seal may also advantageously be non-rotatably fixed relative to the longitudinal axis of the respective fixing hole, so that twisting of the face seal on the sealing surface is avoided.
In a further advantageous configuration of the second positive-locking contour, the second positive-locking contour is formed by a molding facing radially outward, wherein the molding and the stepped recess form a positive lock. The radial molding may extend radially outwards by a few millimetres and substantially corresponds to the width of the stepped recess of the first form-fitting profile. In order to form the first positive-locking contour and the second positive-locking contour as a positive-locking and to arrange the surface seal against the connecting body, the height of the stepped recess along the respective longitudinal axis and the distance of the molding on the web to the respective fixing opening are matched to one another.
In an alternative configuration of the second positive fit contour, the second positive fit contour is advantageously formed by a radially outward edge, wherein the edge and the stepped recess form a positive fit. The edge may extend radially outwards for a few millimetres and substantially corresponds to the width of the stepped recess. Advantageously, the height of the stepped recess along the respective longitudinal axis and the distance of the edge on the tab to the respective fixing opening are matched to one another such that the edge and the stepped recess constitute a form fit and the surface seal is arranged against the sealing surface of the connecting body.
Alternatively, the second positive-fit contour is formed by a radially outwardly and rearwardly engaging edge, wherein the rearwardly engaging edge and the stepped recess achieve a positive fit. The rearwardly engaging edge may facilitate placement of the respective tab in the respective securing aperture. Similarly to the other embodiments of the second positive-fit contour, the height of the stepped recess along the respective longitudinal axis and the distance of the rearwardly engaging edge on the web to the respective fixing opening also match one another here. The width of the rearwardly engaging edge may substantially correspond to the width of the stepped recess and be a few millimetres in length.
Alternatively, the second positive-locking contour is advantageously formed by a radially outward tongue-shaped element on the respective tab. The tongue-shaped element of the second positive-locking contour advantageously forms a positive-locking fit with the stepped recess of the first positive-locking contour, so that the surface seal bears against the plate-shaped connecting body. The radially outward tongue-shaped element can be punched out, for example, in a corresponding tab.
In a particularly advantageous further development of the sealing device according to the invention, the clamping device comprises two webs and the first positive-fit contour is formed by two stepped recesses, wherein the respective recess and the respective web form a positive fit. Advantageously, in this way, the surface seal can be fixed on the sealing surface of the connecting body axially, radially and non-rotatably with respect to the longitudinal axis of the respective fixing hole. It is therefore possible to avoid displacement and distortion of the face seal on the sealing surface and detachment of the face seal from the connecting body. The mounting of the sealing device on the exhaust gas cooler is thus significantly simplified and the sealing is improved. In a particularly preferred embodiment of the surface seal, the two tabs on the respective fixing opening and the two recesses in the respective fixing hole are arranged offset by 180 °.
In order to simplify the fastening of the surface seal to the connecting body, the surface seal is made of metal, preferably spring steel. The clamping device and thus at least one web of the metal surface seal are elastic, so that the surface seal can be fixed to the connecting body and, if necessary, can be detached from the connecting body. However, the form fit prevents an undesired detachment of the face seal from the connecting body during installation or transport of the sealing device.
With the sealing arrangement according to the invention, the transport and installation of the entire sealing arrangement is simplified and a secure sealing of the exhaust gas cooler is made possible.
Further important features and advantages of the invention can be taken from the dependent claims, the drawings and the associated description of the drawings by way of the figures.
It is to be understood that the features mentioned above and still to be explained below can be used not only in the respective combinations stated but also in other combinations or alone without departing from the scope of the present invention.
Preferred embodiments of the present invention are illustrated in the accompanying drawings and described in more detail in the following description, wherein like reference numbers indicate identical or similar or functionally identical elements.

Fig. 1 shows a view of a sealing device 1 according to the invention, and fig. 2 shows a cross-sectional view thereof. The sealing device 1 is used for an exhaust gas cooler and comprises a plate-shaped connecting body 2 and a surface seal 3, which abuts against a sealing surface 4 of the connecting body 2. The face seal 3 may be made of metal, preferably spring steel. The connecting body 2 comprises an air guide channel 5a extending through the connecting body 2, which corresponds to the air guide opening 5b of the face seal 3. Furthermore, the connecting body 2 comprises two fixing holes 6a and 7a, which correspond to the respective fixing openings 6b and 7b of the face seal 3. At each fixing opening 6b and 7b, the face seal 3 comprises a clamping device 8, respectively, integrally formed on the face seal 3, which engages in a corresponding fixing hole 6a and 7a of the connecting body 2. Each fixing hole 6a and 7a has a first positive-fit contour 10a on the inner circumference 9 and each clamping device 8 has a second positive-fit contour 10 b. The first positive-fit contour 10a and the second positive-fit contour 10b achieve a positive fit and in the process fix the face seal 3 to the sealing surface 4 of the connecting body 2.
Each first positive-fit contour 10a is formed by two stepped recesses 11a, respectively, in the respective fixing hole 6a and 7a facing away from the sealing surface 4, and each clamping means is formed by two tabs 11b, respectively, engaging in the respective stepped recesses 11a and having a second positive-fit contour 10 b. The corresponding recess 11a and the corresponding web 11b form a positive fit, so that the face seal 3 is fixed to the connecting body 2 axially to the longitudinal axis 12 of the fixing bores 6a and 7a, respectively. In this embodiment, the second positive-form fit contour 10b on the respective tab 11b is formed by a radially outward edge 13, wherein the edge 13 engages with the stepped recess 11 a.
The tabs 11b and the stepped recesses 11a are arranged on the respective fixing openings 6b and 7b and the respective fixing bores 6a and 7a, respectively, offset by 180 °, and the surface seal 3 is fixed on the sealing surface 4 of the connecting body 2 axially, radially and non-rotatably relative to the respective longitudinal axis 12 of the respective fixing bores 6a and 7 a. Thus, displacement and twisting of the face seal 3 on the sealing surface 4 and falling-off of the face seal 3 from the connection body 2 are avoided. The mounting of the sealing device 1 on the exhaust gas cooler is thus significantly simplified and the sealing of the exhaust gas cooler is improved. Furthermore, the respective webs 11b are arranged completely in the respective fastening holes 6a and 7a, so that the risk of damage during mounting of the sealing arrangement 1 on an exhaust gas cooler is also reduced.
The inner circumference 9 of each fixing hole 6a and 7a is partly formed by a circular hole circumference 14 and partly by two stepped recesses 11 a. The stepped recess 11a and the tab 11b are located radially outside the bore periphery 14. The sealing device 1 can thus be fixed to the exhaust gas cooler by means of a screw connection, wherein the screw connection can extend over the entire length of the respective fixing opening 6a and 7 a. In this way, the sealing device 1 can be firmly fixed to the exhaust gas cooler and the sealing of the exhaust gas cooler is improved.
Fig. 3 shows a view of a sealing device 1 according to an alternative configuration of the invention, and fig. 4 shows a cross-sectional view thereof. In this embodiment, the second positive-locking contour 10b on the respective web 11b is formed by a radially outward molding 15. The webs 11b with the molding 15 and the stepped recesses 11a form a positive fit, as a result of which the surface seal 3 is fixed on the sealing surface 4 of the connecting body 2 axially, radially and non-rotatably relative to the respective longitudinal axis 12 of the respective fixing bores 6a and 7 a.
In fig. 5, a view of a sealing device 1 according to an alternative configuration of the invention is shown, and in fig. 6a sectional view thereof is shown. Here, the second positive-locking contour 10b on the respective tab 11b is formed by an edge 16 which engages radially outwards and rearwards. The corresponding tab 11b with the rearwardly engaging edge 16 is form-fitted with the corresponding recess 11a, so that the face seal 3 is fixed against the sealing surface 4 of the connecting body 2. Here again, the face seal 3 is fixed axially, radially and non-rotatably relative to the respective longitudinal axis 12 of the respective fixing bores 6a and 7 a.
Fig. 7 shows a view of a sealing device 1 according to a further alternative configuration of the invention, and fig. 8 and 9 show sectional views thereof. In this embodiment, the face seal 3 comprises a second positive-fit contour 10b in the form of a tongue element 17 on the respective tab 11 b. The tongue-shaped elements 17 are directed outwards and are punched out, for example, in the respective webs 11 b. The surface seal 3 is fixed axially, radially and non-rotatably relative to the respective longitudinal axis 12 of the respective fixing hole 6a and 7a by means of a tongue-shaped element 17 in the respective tab 11 b.
By means of the form-fit of the first form-fit contour 10a in the respective fixing holes 6a and 7a of the connecting body 2 and the second form-fit contour 10b of the clamping device 8 of the surface seal 3, the surface seal 3 is fixed against the sealing surface 4 and axially fixed relative to the respective longitudinal axes 12 of the fixing holes 6a and 7 a. By means of every two webs 11b and every two stepped recesses 11a, the surface seal 3 is also fixed radially and non-rotatably relative to the respective longitudinal axis 12 of the fixing bores 6a and 7 a. Overall, the face seal 3 in the sealing arrangement 1 according to the invention is firmly fixed against the connecting body 2, thus simplifying the transport and installation of the sealing arrangement 1 on an exhaust gas cooler.
