Abstract: A bump stop device comprises a bearing 20 provided with two bottom 22 and top 24 metal washers between which rolling bodies 26 are arranged. A friction ring 34 is fixed to the first of the bottom and top metal washers and rubs against the other metal washer in order to create a static frictional torque that is greater than that of the rolling bodies and, in practice, greater than 1 Nm. The friction ring 34 makes it possible to generate a controlled resisting torque that limits the transmission to the steering column of the torque generated when driving the vehicle on a convex road.

Abstract: A Macpherson strut of a vehicle is equipped with a coil spring (10) and a telescopic damper, and a bump stop. The stop comprises a strut bearing (24), an upper support element (18) for transmitting the forces of the telescopic damper and of the bearing to a superstructure of the vehicle, a lower support element (38) made of synthetic material for transmitting to the lower washer the forces exerted by the spring, a cover (22) protecting the bearing and disposed between the upper washer and the upper support element, along with a vibration filtration block (32, 60) of the spring. The bearing is equipped with a lower metal washer (28) rotating in relation to an upper metal washer (26). The cover (22) is disposed between the upper washer and the upper support element and delimits with the lower support element a housing for the bearing. The filtration block is disposed between the upper washer and the cover or built into the cover.

Abstract: This invention concerns a system for the attachment of an information sensor opposite to, and at an air gap's distance from, the coder of a bearing, with the system including a cap to be associated with a ring that at least partly covers the coder, where, in combination, the cap includes at least one device for attachment of the sensor to the internal surface of the cap and one device for electrical connection of the sensor. The invention also concerns a sensor designed to be attached to such a system, an ensemble formed by the attachment system and the associated sensor, as well as a bearing equipped with such an ensemble.
