  • Integral ABS exciter ring for cast iron hub
    Patent number: 5350041
    Abstract: A unitary hub and exciter ring for a motor vehicle equipped with an anti-lock braking system (ABS). The exciter ring is unitarily formed in the hub by machining grooves into the exterior surface of the hub and creating spaced teeth about the circumference of the hub. To ensure roundness and concentricity in the hub, and to ensure close tolerances in spacing between the ABS sensor and the teeth, machining is gaged off of bearing cups mounted within the internal bore of the hub.

  • Integral ABS exciter ring for cast iron hub
    Patent number: 5332065
    Abstract: An integral hub and exciter ring is disclosed for a motor vehicle equipped with an anti-lock braking system in which the exciter ring is integrally formed with the hub by machining grooves into the hub forming spaced teeth about the circumference of the hub. To improve the magnetic permeability of the teeth as compared to the cast iron of the hub, a steel band is insert cast into the hub resulting in a steel band having improved magnetic permeability and also being molecularly bonded to the cast iron to ensure retention of the band in the hub.
