Abstract: The present invention relates to a suspension bearing device, comprising a rolling bearing forming an axial stop along a main axis and at least one seal adapted for protecting the rolling bearing from ingress of water or of polluting particles. The device is characterized in that it also comprises a bottom cup and a top cup made of plastic, in contact with the rolling bearing, the bottom cup forming a bearing means for a suspension spring, and in that the or each seal is made of thermoplastic overmolded onto a first element between the cups and comprises a base of substantially annular shape from which extends at least one sealing lip in contact with the second element between the cups. The invention also relates to a strut of a motor vehicle, comprising a damper and a suspension bearing device as mentioned above.

Abstract: The present invention concerns a suspension thrust bearing device adapted to receive a shock absorber piston rod along a main axis (X1), the device including a single bearing forming an axial thrust bearing and including an inner race, an outer race and rolling members disposed between the inner race and the outer race, and at least one intermediate member adapted to transmit to the inner race essentially axial forces exerted on the device by a suspension spring. One of the inner race and the intermediate member extend(s) radially beyond the outer race in the direction of the main axis (X1), forming a bearing surface for fixing and centering the shock absorber piston rod relative to the device. The invention also concerns a motor vehicle McPherson strut including a shock absorber and a suspension thrust bearing device as referred to above.

Abstract: A suspension thrust bearing device having a lower cover, an upper cover and a rolling bearing disposed between the lower cover and the upper cover. The rolling bearing providing a lower ring mounted on the lower cover and an upper ring mounted on the upper cover. The rolling bearing further providing rolling elements disposed between the two rings. The lower cover has a body formed of a rigid material part and a flexible material part forming a seal of the device. The flexible part of the lower cover includes at least one labyrinth sealing lip that cooperates with the upper cover to leave a narrow passage forming a labyrinth seal between one edge of the labyrinth sealing lip and the upper cover and at least one rubbing sealing lip in contact with the upper cover.

Abstract: The present invention relates to a method for manufacturing a suspension bearing device, comprising at least one rolling bearing, a bottom cup and a top cup made of plastic, each in contact with the rolling bearing, and at least one seal suitable for protecting the rolling bearing from ingress of water or of polluting particles. The method is characterized in that it comprises at least one step of positioning a seal made of thermosetting elastomer on a supporting element made of plastic between the bottom cup and the top cup and, for the or each seal made of thermosetting elastomer, a step of curing this seal on its supporting element. The invention also relates to a suspension bearing device and a strut of a motor vehicle.
