Estimating the term…
A hub and bearing assembly particularly adapted for motor vehicle application having anti-lock braking system (ABS). Wheel speed sensors are provided in accordance with this invention having a tone wheel configured from a support substrate having a layer of magnetic ink coated thereon. The magnetic ink is magnetized after coating and can be used in conjunction with passive sensors such as variable reluctance types, or active sensors including semi-conductor Hall effect types. The wheel speed sensors of this invention can be adapted for driven or non-driven wheel applications and are sufficiently compact to enable the device to be integrated into the bearing structure and protected from environmental exposure.
A rotation sensor for detecting relative rotation between two components which are coupled by an anti-friction bearing, comprising:
A rotation sensor for detecting rotation of a motor vehicle wheel mounted to the vehicle through a wheel bearing having inner and outer bearing races with rolling elements therebetween, comprising:
