| 摘要 |
The invention concerns a locked antifriction bearing, for control wheel, comprising an outer part (1) and an inner part (8), one being rotating and the other non-rotating through at least a row of rolling elements (12) arranged between said rotating and non-rotating parts, said device further comprising means for detecting rotation parameters and means for braking (33) the rotating part. The braking means comprises 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 means comprises at least an elastic washer (38) for providing axially prestressed mutual contact of the friction surfaces of the discs. |
