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.
A drive shaft comprising a first gearbox side joint, which is connected to a first shaft section, a second differential side joint, which is connected to a further shaft section, and at least one central joint, which is connected to the first shaft section and to a further shaft section, wherein at least the gearbox side joint and the differential side joint are ball joints each comprising an inner hub and outer hub, in each of which tracks are arranged in pairs, wherein at least one ball is disposed in each pair of tracks between the outer hub and inner hub in order to transmit torque between the inner and outer hubs, and wherein at least one boot made from a rubber-elastic material is provided for sealing the outer hub relative to a connecting section connected in a rotationally fixed manner to the inner hub;
