Abstract

See full text

A flexible connection arrangement for connecting a pipe of an exhaust system to an engine is provided at one of its axial ends with a fastening flange and at its other axial end with a connection piece for the end of the pipe to be received. The connection piece and fastening flange are connected with one another via a helical spring. A metallic bellows and a damping insert which extends coaxially to the bellows, encloses the bellows radially externally and contacts the turns of the bellows are provided between the connection piece and the fastening flange. The helical spring is connected at both of its axial end regions with the connection piece and fastening flange, respectively. The connection at the fastening flange is effected via two fastening locations, one of which lies at that end of the helical spring, while the second fastening location is arranged so as to be offset to the first fastening location by an angle of 45.degree. to 53.degree.. The first fastening location viewed in the winding direction of the helical spring lies at an angle in the range of 10.degree. to 20.degree. in front of a radial tilt axis running vertical to the longitudinal axis of the connection arrangement, the connection arrangement being tilted about this tilt axis when used in the prescribed manner.
