ABSTRACT:
A lightweight ball-and-socket joint that is for instance capable of being assembled by a robot. The ball-and-socket joint has a ball head, a CIRCLIP and an outer structural part forming a socket, in which there is a circumferential groove the bottom of which forms a support face for the circlip. The support face is substantially defined by a hollow cone and surrounds the CIRCLIP like a jacket, and a flare angle of the support face opens toward the center of the ball head. The CIRCLIP presses with radial bias against the support face and therefore migrates in the direction of its largest diameter and hence toward the center of the ball head until it rests thereon.
