ABS tone ring mounting structure

A method of manufacturing a wheel end assembly comprising:

• providing a disc brake rotor with at least one first axial end surface and a first thread extending radially and non-cantilevered from said disc brake rotor;
• providing a tone ring formed with at least one second axial end surface and a second thread extending radially from said tone ring;
• threading said second thread of the tone ring into said first thread of the disc brake rotor;
• and
• moving said at least one second axial end surface in a direction toward said at least one first axial end surface during the threading step.

Tone ring mounting structure for an antilock braking system for use with a heavy-duty vehicle, the tone ring mounting structure comprising:

• a disc brake rotor having at least one axial end surface and a first thread extending radially and non-cantilevered from said disc brake rotor;
• a tone ring formed with at least one second axial end surface and a second thread extending radially from said tone ring, wherein threaded engagement of said first thread of the disc brake rotor and said second thread of the tone ring moves said at least one second axial end surface in a direction toward said at least one first axial end surface so the at least one second axial end surface is forced against the at least one first axial end surface to inhibit relative axial movement in a first direction and relative rotational movement between said tone ring and said disc brake rotor;
• and
• securing structure to prevent relative rotational movement between the tone ring and the disc brake rotor.

An attachment structure for a heavy-duty vehicle with an antilock braking system, the attachment structure comprising:

• a disc brake rotor having at least one first axial end surface and a first engagement structure extending radially and non-cantilevered from said disc brake rotor;
• a tone ring having a plurality of teeth for disrupting a magnetic field produced by an associated antilock braking system, said tone ring having a second engagement structure extending radially from the tone ring corresponding to said first engagement structure and at least one second axial end surface, wherein connecting engagement of the first engagement structure of the disc brake rotor and said second engagement structure of said tone ring moves said at least one second axial end surface in a direction toward said at least one first axial end surface, whereby the second engagement structure and said first engagement structure cooperate to secure the tone ring to said disc brake rotor and form an interface between said tone ring and the said disc brake rotor;
• and
• said interface having a wet zinc-rich coating, whereby said coating resists or prevents rust build-up at the interface.
