摘要:
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.

The invention relates to a rolling bearing 1 comprising a lower ring 3 mounted inside a lower annular cup 6, an upper ring 2 mounted inside an upper annular cup 7, and at least one row of rolling elements 4 positioned between raceways defined by lower and upper rings. One of the annular cups has at least one annular skirt 6d partly inserted within at least one annular groove 7m provided in the other annular cup, thus forming a sinuous chamber 8, and the sinuous chamber is at least partly filled with at least one waterproof grease material 9.

The suspension thrust bearing device for a motor vehicle comprises a rolling bearing forming a thrust bearing and provided with an upper ring, with a lower ring and with at least one row of rolling elements arranged between the rings, a bearing cap in contact with the upper ring, and a support cap in contact with the lower ring and forming a bearing means for a suspension spring. At least one of the caps comprises a body made of synthetic material and an insert covered at least in part by the body. The insert comprises stiffening ribs in order to reinforce the mechanical strength of the cap with respect to the axial loads resulting from the forces exerted by the suspension spring.

A suspension thrust bearing device includes a lower cap, an upper cap having a surface portion, and a bearing disposed between the two caps. The bearing includes a lower race mounted on the lower cap, an upper race mounted on the upper cap, a plurality of rolling elements disposed between the two races, and a cage for retaining the rolling elements. The cage has a holding part for the rolling elements and a sealing lip extending from the holding part towards a periphery of the bearing, the lip including first and second integral legs extending in opposing directions. In certain embodiments, the first leg cooperates with the upper cap surface portion and the second leg cooperates with the lower race to form a seal. In other embodiments, the first leg cooperates with the lower race and the second leg cooperates with the upper cap surface portion to form a seal.

The suspension thrust bearing device for a motor vehicle comprises a rolling bearing 22 forming a thrust bearing and provided with an upper ring, with a lower ring and with at least one row of rolling elements arranged between the rings, a bearing cap 18 in contact with the upper ring, and a support cap 20 in contact with the lower ring and forming a bearing means for a suspension spring 12. At least one of the said caps comprises a body made of synthetic material and an insert 34 covered at least in part by the said body. The insert 34 comprises stiffening ribs 44 in order to reinforce the mechanical strength of the said cap with respect to the axial loads resulting from the forces exerted by the suspension spring.

The suspension thrust bearing device comprises a rolling bearing 44 forming an axial stop and a support element 42 for the rolling bearing forming bearing means for a spring, the rolling bearing comprising a bottom ring 48 in contact with the support element, a top ring 46 and a plurality of rolling elements 50 positioned between the rings. The support element 42 comprises a body 60 and a stiffening insert 66 at least partly covered by the body. The body is formed of a rigid material 62 for the transmission of axial forces between the spring and the rolling bearing and a flexible material 64 to provide at least one dynamic seal 84b, 86b inside the device. At least a part of the rigid material is situated radially between the flexible material and the stiffening insert.
