Abstract

A flexible joint for an automobile exhaust system includes a flexible bellows for sealing the communication between the engine and the tail pipe with first and second flanges fixed to the respective members and interconnected by coupling shafts that are fixed at one end to one of the flanges and passed loosely through the other flange whereby compression springs that surround the coupling shafts serve together with the bellows to provide support capable of accommodating relative axial and angular deflections between the members. One of the flanges is so configured and disposed with respect to the bellows as to limit the amount of angular deflection imposed on the bellows. Damping sleeves composed of compressed wire mesh material operate to dampen vibrations imposed on the joint.
