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.
Claims6
An integral hub and exciter ring assembly for a motor vehicle having an anti-lock braking system comprising:
- a cast iron hub having means for affixing a wheel to said hub and means for rotatably mounting said hub to a suspension structure of a motor vehicle, said hub defining an exterior substantially cylindrical surface;
- a ring bonded to said cast iron hub and being of a material having a magnetic permeability greater than cast iron, said ring including a surface coincidental with said substantially cylindrical surface of said hub;
- and
- spaced teeth formed in said ring, said teeth including a radial surface coincidental with said substantially cylindrical surface of said hub, said teeth formed by grooves in said ring between said teeth, said teeth joined to one another by a base portion of said ring extending between said teeth at said grooves.
