A suspension stop for a motor vehicle has an upper cup, a lower cup and roller bodies arranged between the cups to permit the relative rotation thereof. The cups are designed to have at least one annular space between them. The stop further has a seal element arranged in the annular space with a sliding contact with each cup. The seal element is arranged to be mobile with relation to at least one cup.

A bump stop device comprises a bearingprovided with two bottomand topmetal washers between which rolling bodiesare arranged. A friction ringis 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 ringmakes 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.
