Abstract
A ball-and-socket joint with integrated angle sensor for a motor vehicle, especially for the chassis of the motor vehicle is created. The ball-and-socket joint has a ball-and-socket joint housing () provided with a joint opening (), a ball pivot () having a joint ball () and a pin (), which is mounted, with its joint ball (), rotatably and pivotably in a hollow-ball-shaped bearing surface in the ball-and-socket joint housing (), and projects, with its pin (), through the joint opening () out of the ball-and-socket joint housing (). A two-pole field transducer () is provided at the end of the joint ball () facing away from the pin (). The poles of the field transducer () are arranged on the ball surface. In this case, at least two field sensors () are arranged at a distance from one another with respect to the meridian plane defined by the large circle on the hollow-ball-shaped bearing surface running at right angles to the bearing longitudinal axis in the area or on the ball-and-socket joint housing () facing away from the joint opening, and interact with the field produced by the field transducer ().
