避けられるが、ハニカム体のスリーブへの所定の結合が達成されない。International Patent Application Publication No. 99/37896 describes a method of manufacturing a jacket-shaped honeycomb body. The envelope-shaped honeycomb body has a plate-like metal layer which is formed by stacking and / or winding and is at least partially microstructured so that the honeycomb body has passages through which exhaust gas can flow. . The honeycomb body is surrounded by the jacket tube. Honeycomb bodies and jacket tubes exhibit different thermal expansion behaviors based on their different material properties and different temperatures during operation. Therefore, care is taken to avoid a firm bond between the honeycomb body and the jacket tube in at least one end region of the honeycomb body. For this reason, sleeves are provided on the envelope honeycomb body. The sleeve ensures that, regardless of the manufacturing tolerances of the jacket tube and the honeycomb body, direct brazing of the honeycomb body and the jacket tube in at least one end region of the honeycomb body is avoided. During the manufacture of this type of honeycomb body, some contact points between the honeycomb body and the sleeve happen to be bonded to each other, but most contact points remain unbonded. In that way, indeed, thermal stresses between the jacket tube and the honeycomb body are avoided, but the desired bonding of the honeycomb body to the sleeve is not achieved.

を塞いだり、隣接する排気装置の構成要素を損傷したりする危険がある。This type of envelope-shaped honeycomb body used as a catalyst carrier in an exhaust device receives not only thermal load but also dynamic load. This means that the movably arranged end area of the honeycomb body vibrates. The contact points that are not firmly fixed loosen, and the plate-shaped metal edges that are not fixed freely fluctuate, and as a result, the catalytic layer separates. Furthermore, there is the risk that this free-flickering part of the honeycomb body will loosen, blocking adjacent passages and damaging adjacent exhaust system components.

Another object of the present invention is to provide a catalyst carrier capable of avoiding free end and wavy plate-shaped metal wobble.

し、大きな寿命を示す。The catalyst carrier according to the present invention comprises a honeycomb body composed of a plate-shaped metal layer, and the plate-shaped metal layer has at least a part of a fine structure so that the honeycomb body forms a passage through which exhaust gas can flow. Be converted. The honeycomb body is at least partially surrounded by a jacket tube. The jacket tube is joined to the honeycomb body in a joining method only in at least one axial subrange. The joining by the joining method means a physical joining by adhesion, brazing, welding or the like. A sleeve, which is shorter than the axial length of the honeycomb body, comes into contact with the inner wall portion of the jacket tube. The sleeve is arranged near the end face of the outer periphery of the honeycomb body.
According to the present invention, the inner peripheral surface of the sleeve is joined to the end area located radially outside the end surface side of the plate-shaped metal layer of the honeycomb body by the joining method in order to prevent the end area from wobbling. To do. The termination range located on the outer side in the radial direction of the plate-shaped metal layer is
Due to the coupling with the sleeve, no individual vibration occurs. As a result, the catalytic layer does not move even under a large dynamic load. The loosening of this end region from the honeycomb body is prevented, so that the catalyst carrier has the best effect on the generation of harmful substances and has a long life.

に対し熱膨張した際、スリーブが移動可能な点で優れている。かくして、触媒担
体の熱的負荷の下での、外被管とハニカム体の異なる熱膨張を補償する。In another embodiment of the present invention, the catalyst carrier of the catalytic converter is excellent in that the sleeve can move when the honeycomb body thermally expands with respect to the jacket pipe. Thus, different thermal expansions of the jacket tube and the honeycomb body are compensated for under the thermal loading of the catalyst support.

【０００９】 スリーブを少なくともハニカム体の端面迄延ばし、板状金属層の終端範囲に結
合するとよい。この結果、板状金属層の終端範囲を特に強固に固定できる。The sleeve may be extended at least up to the end face of the honeycomb body and bonded to the end region of the plate-shaped metal layer. As a result, the terminal area of the plate-shaped metal layer can be fixed particularly firmly.

Thus, during insertion of the honeycomb body and / or during operation of the catalyst carrier, a stopper is provided which prevents the honeycomb body from penetrating into the jacket pipe beyond a predetermined insertion depth.

その全長にわたって形成される。In another embodiment of the invention, the sleeve has at least one microstructure. As a result, the sleeve exhibits a small contact surface with the jacket tube. This is particularly advantageous in that when the honeycomb body thermally expands, the sleeve can easily move due to a small frictional force against the jacket pipe, and thermal stress between the jacket tube and the honeycomb body can be prevented particularly well.

This means arranging the microstructures on the sleeve in a circumferential, longitudinal or spiral fashion. Microstructures of this kind are known, for example, from EP 454712.

【００１３】 本発明の他の実施態様では、例えば国際特許出願公表９６／０９８９２号明細
書で知られているように、複数の微細構造が交差している。In another embodiment of the invention, a plurality of microstructures are intersected, as is known, for example, from WO 96/09892.

ーブの内周面はハニカム体に良好にろう付けできる。In particular, it is advantageous to form the sleeve such that the at least one microstructure only faces radially outwardly, ie towards the jacket tube. In this way, only a very small contact surface, which is simply spot-shaped, is partially produced, so that the sleeve is prevented from sticking to the jacket tube. In addition, since the linear contact surface between the honeycomb body and the sleeve is generated at least partially, the inner peripheral surface of the sleeve can be brazed to the honeycomb body well.

In the carrier, according to another embodiment of the invention, the inner peripheral surface of the sleeve is joined to at least one plate-shaped metal end in contact with it by a joining method. The inner peripheral surface of the sleeve may be joined to all of the plate-shaped metal ends in contact with it by a joining method.

着によって、意図的に或いは意図なしに生ずる。In another embodiment of the invention, the joint between the sleeve and the honeycomb body exhibits greater strength than the joint that occurs between the sleeve and the jacket tube due to manufacturing conditions. This high strength ensures that the stresses caused by the different thermal expansions are eliminated by first breaking the connection between the sleeve and the jacket tube. The connection between the sleeve and the jacket tube occurs intentionally or unintentionally during the manufacture of the catalyst carrier, especially by pre-fixing or unintentional point-like fixing of the sleeve in the jacket tube.

In particular, it is advisable to braze the honeycomb body to the jacket tube at high temperature. This combination is advantageous in that it also withstands the extreme thermal and mechanical conditions that occur in exhaust systems of internal combustion engines of motor vehicles, in particular catalyst supports installed near the engine.

First, a honeycomb body is formed in a known manner by laminating and / or winding at least partially microstructured plate-like metal layers so as to form passages through which exhaust gas flows. Then, the sleeve is put in the jacket tube, and the outer peripheral surface of the sleeve is brought into contact with the inner wall portion of the jacket tube. In that case, the sleeve may be arranged in the envelope tube so that it lies near the end face area of the honeycomb body in the assembled state. Subsequently, a brazing material is applied to at least one annular circumferential area of the inner wall of the jacket tube and the inner peripheral surface of the sleeve. Next, put the honeycomb body in the jacket tube and the sleeve,
The end face of the honeycomb body is made to project from the edge of the jacket pipe in the vicinity of the sleeve. An adhesive is applied to the protruding end surface of the honeycomb body and the outer area near the protruding end surface. The axially protruding portion of the honeycomb body facilitates application of the adhesive. Subsequently, the honeycomb body is completely put into the jacket tube and the sleeve. Then, a brazing material, particularly a brazing powder, is adhered to the end face side of the honeycomb body to attach the brazing material. Particularly after this step, it is advantageous for the wax powder to be present in the outer area between the sleeve and the honeycomb body in the vicinity of the end faces of the honeycomb body. After that, the honeycomb body and the jacket tube and the honeycomb body and the sleeve are brazed together.

【００２０】 本発明に基づく方法の有利な実施態様では、スリーブをハニカム体の板状金属
