ABSTRACT:
A wheel bearing with a speed of rotation detection device, in particular for use on a motor vehicle. A sensor supported on the stationary bearing ring is opposite a pulse ring which is connected with and rotates with the rotating bearing ring. The pulse generating ring is developed as a spherical segment, spherical sector, or spherical zone, wherein the center point of its sphere is arranged at the tilt center point of the bearing. The sensor is concentric to the center point of the sphere and is opposite and spaced from the pulse ring by an air gap. The sensor may be concentric with or eccentric to the axis of rotation of the bearing ring. This develops the pulse generating ring and the sensor such that the change in the air that gap occurs as a result of static or dynamic loads on the bearing has no detrimental effect on the quality of the signal.
