Patent number: 7867098Abstract: A ball-and-socket joint comprising an inner hub (1) and an outer hub (6) inside which tracks are disposed that are associated with each other in pairs. At least one ball is arranged in each track in order to transmit torque between the inner hub and the outer hub. The ball-and-socket joint further includes at least one diaphragm which seals the outer hub with respect to a joining element that can be connected in a torsion-proof manner to the inner hub. The outer hub is provided with a metallic interior element encompassing the tracks, a dampening element which embraces the interior element in at least some areas, and a cap that embraces the damping element in at least some areas in order to connect the outer hub to a driving part or a part to be driven. The damping element is made of a material having a modulus of elasticity lower than the modulus of elasticity of the metallic material of the interior element and/or the cap of the outer hub while being greater than the modulus of elasticity of the diaphragm.Type: GrantFiled: March 25, 2010Date of Patent: January 11, 2011Assignee: Shaft-Form-Engineering GmbHInventors: Werner Jacob, Martin D.
