Patent ID: 8888372

Claim:
A sensor-carrier cap for a bearing of a wheel hub, the cap being made of plastic material and comprising: a bottom wall arranged transversely to a central axis (A) and providing a seat for accommodating a rotational speed detecting sensor, a cylindrical mounting wall extending axially from one side of the bottom wall around said axis (A), and snap locking means projecting in a radially outer direction from the cylindrical mounting wall, for locking the sensor-carrier cap on a tubular appendage of a wheel hub bearing, the snap locking means comprising a protuberance located on a radially outer surface of the cylindrical mounting wall at an axial end of the cylindrical mounting wall opposite from the bottom wall, the protuberance including an edge portion and a connecting portion and being configured such that, when the cylindrical mounting wall is viewed in radial cross section, none of an outer surface of the protuberance is colinearly aligned with and parallel with the radially outer surface of the cylindrical mounting wall, wherein the cylindrical mounting wall and associated snap locking means are devoid of metallic reinforcements.
