The invention concerns a flexible pipe element, in particular for exhaust pipes of combustion engines of motor vehicles, with a helically threaded or ring-corrugated bellows, at least one strip wound hose which is coaxially adjacent to the bellows and which is helically wound or comprises several annular segments, at least one spacer which is disposed locally between the bellows and the strip wound hose and a knitted tube disposed on the outside, wherein the pipe element has an overall maximum rigidity of 5 N/mm.

Flexible pipe element

The invention is a flexible line element, particularly for exhaust pipes of internal combustion engines of motor vehicles. At least two interconnected, metal bellows are provided with cylindrical joining ends and at least one of the bellows may be helically corrugated. The bellows may be telescoped. The two bellows, whether in line or telescoped, are connected at only one of their joining ends. A line element of the invention is on the one hand torsion-soft to not transfer any torsional stresses to adjacent components, and on the other is also stable in the case of high torsional stresses.

Flexible line element

In a device for the bearing of a component of a motor vehicle such as an exhaust gas assembly on the chassis of the motor vehicle, connecting components are provided for mounting respectively to at least the chassis of the motor vehicle and to the component which can move relative to each other, and which engage at least one damped resilient wire element.

Device for mounting a component

A flexible line element, particularly for exhaust pipes of internal combustion engines of motor vehicles, is disclosed having a screw thread-like or annularly corrugated bellows provided with cylindrical connection ends and a metal netting directly surrounding the bellows. The metal netting is inherently stable and has at least one plastic deformation for acoustic or mechanical damping of the bellows. Consequently, the metal netting has both a protective and a damping function.
