Flexible joint for chassis parts of motor vehicle, has outer tube comprising outer rotation surface that is fixed in cylindrical housing of mechanical part and provided with two barrel-shaped bulged zones

摘要

The joint has an elastomer O-mass (3) arranged between a concentric outer tube (2) and a cylindrical inner tube (1), and connected to the tubes. The outer tube comprises an outer rotation surface fixed in a cylindrical housing of a mechanical part, where the outer rotation surface includes two barrel-shaped bulged zones. The outer tube has two edge rolls that are separated by a dent. A radial difference (e) between an outer part and an inner part of the outer tube is in the order of 1 to 2 mm.
