Abstract

Une butée tournante de suspension (18) comporte un couvercle fixe (20) pourvu d’au moins une première piste supérieure annulaire de glissement (36) et un support inférieur tournant (22) rigide comportant une zone annulaire d’appui (46) pour un ressort hélicoïdal de suspension (12) et une première piste inférieure annulaire de glissement (56) réalisant avec la première piste supérieure annulaire de glissement (36) un premier palier lisse (58) apte à transmettre au support inférieur (22) des efforts axiaux exercés sur le couvercle (20) tout en laissant le support inférieur (20) libre en rotation par rapport au couvercle (20). La zone annulaire d’appui (46) est située radialement à l’extérieur et axialement à distance au-dessus du premier palier lisse (58). (Fig. 2)A rotary suspension thrust bearing (18) comprises a fixed cover (20) provided with at least one first upper annular sliding track (36) and a rigid lower rotating support (22) comprising an annular bearing zone (46) for a helical suspension spring (12) and a first lower annular sliding track (56) forming with the first upper annular sliding track (36) a first slide bearing (58) able to transmit axial forces to the lower support (22) exerted on the cover (20) while leaving the lower support (20) free to rotate relative to the cover (20). The annular support zone (46) is located radially outside and axially at a distance above the first plain bearing (58). (Fig.2)
