Abstract
An exhaust lining for an exhaust system of a motor vehicle has a first connecting element clamped between a first and second pipe. The first pipe forms a tailpipe. The second pipe forms a tailpipe cover. The tailpipe cover has a tubular inner part held on by means of the first connecting element which clings onto the first pipe via by means of a lever mechanism. A load arm of the lever mechanism, having the distance A, is shorter than an effort arm, having the distance B. The length of the effort arm is precisely defined, because the end of the effort arm lies against the first pipe via a punctiform contact area. A first contact surface of a clamping spring is designed offset from the longitudinal extent of a main body of the first connecting element to save space in the longitudinal direction of the main body.
Claims13
An exhaust lining for a motor vehicle, the exhaust lining comprising:
- a first pipe;
- a second pipe;
- wherein the first pipe is arranged radially inside the second pipe;
- an at least partially resilient one-piece first connecting element disposed radially between the first pipe and the second pipe for holding the second pipe to the first pipe;
- the first connecting element being supported on the first pipe both via an end claw of the first connecting element and via a punctiform contact area of the first connecting element, the first connecting element being formed between the contact of the end claw and the punctiform contact area at a distance along the first pipe;
- wherein the first connecting element has a clamping spring in the region of an end opposite the end claw which is tensioned radially between the first pipe and the second pipe;
- wherein the first connecting element is mounted lying against the second pipe in the form of a rocker between the end claw and the punctiform contact area via a projection of the first connecting element, wherein the projection lies against the second pipe;
- wherein the first connecting element lies against the first pipe radially inwardly via the end claw and the punctiform contact area on the first pipe;
- wherein a distance B between the projection and the punctiform contact area corresponds to at least 3 times a distance A between the end claw and the projection.
