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.

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.
摘要:
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.
