Title
(EN) Spring system for connecting two flanges
Abstract
(EN)

A spring system for connecting two flanges (13, 14), for use especially in a motor vehicle exhaust system. The spring system is configured as an elastic, flexible clamp with functionally first (1, 2) and second (4, 5) U-shaped clamping jaws positioned opposite each other. This provides a spring system which is easy to assemble and economical to produce. To this end the spring system has the U-shaped arms (6, 7) of the clamping jaws (1, 2; 4, 5) having only locally very restricted areas (8, 9, 10) for direct application to the pieces (11, 13; 12, 14) to be joined by means of the clamp. Four application areas (8) exercising both clamping functions are present in at least one of the clamping planes (100or200), of which two areas are arranged in pairs and situate diametrically opposite each other.
