A high-temperature seal that is in the form of a seal ring and that connects two pipes, especially single-flow pipes or double-flow pipes forming the conduit of an automobile exhaust system, in an elastically flexible, universal joint type, and separable manner. It is related to materials.

ればならない。 In such a known line system, which is described for example in German Patent Publication No. 2908367 for the exhaust pipe of a truck with a horizontal engine, the lines are interconnected by means of joints, the joints being ball joints. A sealing ring is permanently arranged between the sealing surfaces thus created by the conduit and in close contact with these surfaces. The seal ring must withstand high exhaust temperatures and pressures, allow for universal relative movement of the conduit, be integral and form-stable, and ensure that the seal ring and adjacent members Must have excellent bearing properties to avoid wear between bearings.

をしなければならない。 There are still too many problems with known sealing rings, which over time wear out the sealing surface of the conduit.
It produces a squealing noise, and this noise is particularly unpleasant. Additionally, this wear can lead to damage to the sealing surface and
When replacing a defective seal ring, tedious work is often required to separate the sealing surface from the tight sealing member, resulting in seizure of portions of the ring.

結果、エンジン効率が失われてゆく。 Additionally, known seal rings tend to cave in due to wear and densification of the material. The members, which were initially held at a fixed distance and movable relative to each other by the sealing ring, come into contact with each other, rendering the joint inoperable. Furthermore, the sealing ring loses its sealing effect and must be replaced prematurely. Finally, for example in the case of two-flow conduits, a large sealing gap must initially be maintained between adjacent partitions of the conduits, resulting in a loss of engine efficiency as a result of the pressure balance between the exhaust conduits.

There is no labor involved, saving materials and therefore lower manufacturing costs.

の圧縮度の相違による不均一な剛性分布が音響減
衰に役立つ。 The method according to the invention has the advantage that the following two tasks, which were hitherto only undertaken by seals, are functionally separated from each other. namely, the task of supporting static and dynamic bearing stresses and the performance of a sealing function. In this case, the bearing stresses are taken up only by the supports, which retain their shape, whereas the sealing body only has to carry out its sealing action with its inherent elasticity. This separation of issues significantly reduces seal ring wear and caving and also limits the generation of noise, especially squealing. This is because the relatively strong support removes the spring action of the seal ring by the volume it occupies, so that the seal ring-opposite friction pair becomes much less rocky. Acoustic stimulation is significantly reduced since the static slip phenomenon observed hitherto is prevented. In addition, the frictional stress generated by rocking is not applied over a large area, but is essentially applied only to a narrowly limited pressure surface of the support, and the rocking is diffused from this pressure surface, but is attenuated at that time. Ru. Moreover, locally excited oscillations are partially canceled by interference. Finally, the non-uniform stiffness distribution due to the different degrees of compression between the seal ring and the support and between the supports aids in sound damping.

されるなら、望ましくはこれらの支持体はシー
ル・リングの周囲に沿つて均等に分布される。 As long as the sealing ring has only one support,
This support can be constructed as a circulating structure within the seal ring. If multiple supports are provided, these supports are preferably evenly distributed along the circumference of the seal ring.

に適合させられる。 The support can be in the form of spheres, disks, prisms, irregularly contoured granules, etc., depending on the conditions in each case and the availability of suitable materials. In this case, the shape of at least part of the surface of the support is adapted to the adjacent surface of the sealing ring in such a way as to perform the task particularly locally.

This is because the support is introduced as a protection and is compression molded together during the manufacture of the sealing ring. However, it is also possible, for example, to press the carrier into a specific location of the sealing ring afterwards.

has a cylindrical outer surface forming a sealing surface, while the socket 3 has a spherical inner surface as an opposing sealing surface.
A sealing ring 6 is inserted between these sealing surfaces. The sockets 1 and 4 are elastically and releasably connected by radial flanges and spring elements 9, 10 which abut these flanges against each other.

It is swingable along 6. Since the connecting socket 4 is pivotable relative to the outlet socket 1, the connecting socket 4 slides on the spherical surface 16, which is thus configured as a sliding surface.

性が特定される。 Inside its cross section, the sealing ring 6 has supports 13, 14, the support 13 being designed as a ring, whereas the support 14 has a granular, irregular shape. As can be seen, the support 13 is stretched over all three sealing surfaces of the ring 6, whereas the support 14 has a constant distance 15 from the outer sealing surface. This allows the contour of the sealing ring 6 and the support 13 to 1 to be

In that case, metals with sliding bearing properties are particularly suitable if the support is to be combined with the sealing surface of the joint shown in FIG. However, the support can also consist of inexpensive materials such as ceramics, minerals (rocks), glass, etc.
