  • Patent number: 6131252
    Abstract: A connecting arrangement for an exhaust gas system having two components, an exhaust gas system component which can be subjected to heat and a thermal shielding plate fitted beneath the exhaust gas system component and connected to it, including a connecting member arranged in such a way as to allow relative displacement of the exhaust gas system component and the thermal shielding plate in relation to each other as a result of differential thermal expansion behavior. The connecting member has sliding tongues with sliding surfaces for slidably engaging a first component with a predetermined spring force. Furthermore, the connecting member is rigidly connected to the second component and threaded clamping members make it possible to fix the second component onto the connecting member and to brace the connecting member with the first component.

  • Patent number: 4132285
    Abstract: A connecting line or exhaust pipe for disposal within the exhaust system of a motor vehicle driven by an internal-combustion engine between the exhaust manifold of the engine and the muffler. The connecting line is formed of two bowl-shaped sheet metal half-shells which are preshaped, e.g., by pressing, deep drawing or the like, and which are superposed on one another, and firmly connected together. The half-shells of the connecting line have a shape such that the connecting line has a non-circular substantially flat cross section with respect to its vertical dimension when the connecting line is connected in the vehicle exhaust system.
