Abstract
A ball pivot (3) of a ball and socket joint for a motor vehicle, with a pivot (2) and with a joint ball (1) connected thereto. A recess (12) with a magnet (13) arranged therein is provided in the ball pivot (13). An intermediate space (17), which is filled with a nonmagnetic material (16) for fixing the magnet (13), is formed between the jacket surface (14) of the magnet (13) and the inner wall (15) of the recess (12).
Claims20
A ball pivot of a ball and socket joint for a motor vehicle, the ball pivot comprising:
- a pivot;
- a joint ball connected to said pivot;
- a magnet having a jacket surface, the ball pivot having a recess with said magnet arranged therein, an intermediate space, which is filled with a nonmagnetic plastic to fix said magnet, is formed between said jacket surface of said magnet and an inner wall of said recess, said plastic being completely arranged within said recess.
A ball and socket joint for a motor vehicle, the ball and socket joint comprising:
- a housing;
- a ball pivot mounted rotatably and pivotally in said housing, said ball pivot including a pivot pin and a joint ball connected to said pivot pin;
- a magnet having a jacket surface, the ball pivot having a recess with said magnet arranged therein, an intermediate space, which is filled with a nonmagnetic plastic material to fix said magnet, is formed between said jacket surface of said magnet and an inner wall of said recess, said nonmagnetic plastic material being completely arranged within said recess.
A ball and socket joint for a motor vehicle, the ball and socket joint comprising:
- a housing;
- a magnetic field sensor arranged in said housing;
- a ball pivot mounted rotatably and pivotally in said housing, said ball pivot including a pivot pin and a joint ball, said joint ball defining a recess, said joint ball being formed of a ferromagnetic material around said recess;
- a magnet arranged in said recess to define an intermediate space between said magnet and said joint ball, said intermediate space extending circumferentially around a longitudinal axis of said magnet, said intermediate space being filled with a nonmagnetic material, said nonmagnetic material being of the type and said intermediate space being of a size to optimize a magnetic field that extends out of from said magnet and out of said joint ball for detection by said magnetic field sensor in said housing, said nonmagnetic material also fixing said magnet to said joint ball.
