  • Patent number: 11378381
    Abstract: A magnetic field sensor has a magnet (M1) that produces a magnetic field with a magnetic field axis (f), has a magnet axis (a) and is held in a component (4) that can move about at least one axis and has a component axis (b). Also a method for mounting a magnet (M1) of a magnetic field sensor. The magnet (M1) is held in the component (4) in such a manner that the magnetic field axis (f) coincides, as closely as possible, with the component axis (b). A deviation of the magnetic field axis (f) from the magnet axis (a) is measured, and the angle of deviation (?) is corrected during the mounting of the magnet (M1) in the component (4).

  • Patent number: 9724975
    Abstract: A holding element for a spring, having a spring fastening area (10) for fastening the leaf spring (2) to the holding element (5) and a wheel carrier fastening area (9) for fastening a wheel carrier (4) to the leaf spring (2). The holding element (5) has a deformation zone (23) through which webs and openings extend for transmission of forces from the spring fastening area (10) to the wheel carrier fastening area (9), such that the webs (S2.1, S2:2, S3.1, S3.2) and the openings (A1, A2, A3) are formed mirror-symmetrically relative to the longitudinal axis (L) of the holding element.
