Abstract

A protective cap is described, in particular for a wheel hub, and a system for determining angular velocity of a rotating element, in particular of a wheel of a vehicle, usable in an ABS type anti-locking device; its principal characteristic is the presence of an annular appendage received overhanging a peripheral edge of a lateral wall of the cap, which has been mounted angularly integral with the rotating element whose velocity is to be determined, closing a cavity housing the support bearing of this latter; the appendage is provided with zones of discontinuity, in this particular instance of longitudinal slots disposed circumferentially in succession with a constant spacing along a circular crown; such zones of discontinuity cooperating with a sensor, for example electromagnetic, carried by a fixed support member of the rotating element, able to generate a periodic pulse signal as a function of the number of discontinuities passing across it in unit time. (Figure 2).
