ABSTRACT:
A rotor is provided for use in a wheel speed sensor assembly for sensing angular velocity of a wheel about a wheel support. The rotor is adapted to be mounted to a wheel for rotation therewith about an axis of rotation. The rotor includes a wall portion which extends in an axial direction coaxially about the axis of rotation and terminates in an annular edge portion. The rotor face has ripples or undulations formed therein which define an annular array of lands and recesses for providing wheel speed information to a sensor during wheel rotation. Also, the undulations provide a rotor face structure exhibiting a high degree of stiffness to resist deflection by forces applied to the rotor face. The wall portion also serves as an oil slinger to route oil or grease derived from a wheel hub or the like away from proximately located brake shoes. The rotor may be mounted to a wheel, such as to the brake drum mounting flange, by means of an annular flange which extends radially outward from the wall portion.
