Abstract

A locked antifriction bearing, for control wheel, includes an outer part and an inner part, one being rotating and the other non-rotating through at least a row of rolling elements arranged between said rotating and non-rotating parts, the device further comprising elements for detecting rotation parameters and elements for braking the rotating part. The braking elements comprise an axial stack of discs maintained in frictional contact through at least a disc angularly secured to the non-rotating part and at least a disc integral with the rotating part. The braking elements comprise at least an elastic washer for providing axially prestressed mutual contact of the friction surfaces of the discs.
