Abstract: The tone wheel is a heavy walled steel stamping having a flanged central opening adapted for pressing on to a pilot turned on the outside surface of the wheel hub, and a cylindrical flange contiguous to the usual offset portion of the brake disc and having teeth formed on its inside surface. The spaces between the teeth are filled with adhesive nonmagnetic material so that the tooth tips and the nonmagnetic material provide a smooth unbroken cylindrical surface. A radial adjustment for establishing a predetermined clearance between a pickup and the tone wheel is provided by a generally rectangular projection on the back of the pickup which fits into an elongated slot in the pickup bracket. The output of the pickup is used to control the adaptive braking system.

Abstract: A wheel speed sensor for use in an adaptive braking system comprising a magnetic pickup and a tone wheel. The tone wheel of a so-called ''''frictionless''''-type wheel speed sensor is formed in two pieces, one of which is a low mass disk or cup adapted to be mounted on the outside of the axle flange and be clamped between the brake drum and said flange. The other is a rather massive cross section ring of ferromagnetic material secured to the outer margin of the disk and formed with evenly spaced gearlike teeth. The toothed portion may be formed by rolling a straight rack element into a circular shape.
