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.
Claims5
A unitary hub and exciter ring for a motor vehicle having an anti-lock braking system, said hub and exciter ring comprising:
- a cast hub having a substantially cylindrical body including an outer cylindrical surface and an interior passageway defined by an inner cylindrical surface, means for rotatably mounting said hub to a suspension structure of the motor vehicle for rotation about an axis of rotation;
- and
- an exciter ring unitarily formed with said body of said hub, said exciter ring being defined by a plurality of axial grooves formed in said body and extending axially therealong, said grooves having a radial depth which extends only partially through said body of said hub, said grooves also defining a plurality of axially extending teeth therebetween, said teeth being equidistantly spaced and circumferentially positioned around said body of said hub, said teeth having an outer cylindrical surface coincidental with said outer cylindrical surface of said hub.
