"Improvements to the exhaust system of a motor vehicle."

The present innovation relates to improvements to the exhaust system of a motor vehicle.

There are already known exhaust systems of motor vehicles, in which the exhaust pipe on one of its intermediate Share comprises a ball joint, which through the two end ^ n the exhaust pipe is formed, which are substantially spherically deformed and are inserted into one another. The connection and the seals are each created by the design of the articulated coupling ensured in which the hollow outer joint part exactly the inner spherical joint part of the coupling uasenliesst, whereby the aforementioned properties are also included any suitable mechanical coupling device can be achieved, which the tearing apart or the loosening of the two C-joint parts.

The new pieces are opposing extensions of two essentially rigid flat parts or webs, each attached to each exhaust pipe section are welded. In this way, the elastic connecting device can be produced quickly and reliably.

In a simple exhaust system, each flat web can, for example, have the shape of a half ring that is attached to a. the section of the exhaust line is welded and encloses it, this half ring at its ends with zv / ei lateral extensions are provided which are arranged in the diametrical plane of the half ring and at which the ends the two Eedern are attached.

The respective components of the device are easy to manufacture and the unit can be installed on the exhaust system

Further features of the present innovation result in si -h from the following description, in which on the basis of the attached Drawings various non-limiting exemplary embodiments explained.

In the drawings show:

- Figures 1 and 2 each a plan view urn side view of a connecting device for a simple motor vehicle

- Figures 3 and 4 similar representations of the innovation Connection device for a double exhaust system.

In a simple exhaust, as shown in Figures 1 and 2, a ball joint coupling 155 is formed by the interlocking of two hollow 152b and full 152a collars of two sections 152i and 152e of an exhaust pipe, these two ends being spherically deformed. The elastic connecting device 151 consists of two springs 153 and 154, in particular helical tension springs, which are directed essentially parallel to the axis of the ball joint 155. The ends of the spring 153 are anchored to two side extensions 156a and 157a of two half rings 156 and 157, which are arranged opposite one another on either side of the ball joint, the one half ring being upstream of the ball joint.

These webs are preferably placed in such a way that the springs attached to their extensions are as close as possible are arranged on the plane running through the axis of the ball joint.

Of course, the number of opposing extensions and therefore the number of springs can be changed as desired , whereby the chosen solution depends on the individual cases, bsw. the respective Vehicles is adapted.
