Zusammenfassung: | Provided is a coiled spring assembly in which a coiled spring and seats for the coiled spring, the seats for the coiled spring being seat members, are appropriately engaged with each other to prevent the excessive interference between the end windings of the coiled spring and the seats for the coiled spring, thereby increasing the durability of the coiled spring assembly. Provided is a coiled spring assembly characterized in that: a coiled spring (3) has end windings (9, 11) each wound one turn at a reduced diameter and has transition sections (13, 15) having a diameter gradually increasing from the end windings (9, 11) to a body section (7); seats (5) for the coiled spring have seat sections (17), mounting shaft sections (19), and expanded-diameter sections (21), the mounting shaft sections (19) having a length set so that, in a free state in which the end windings (9, 11) are fitted to the mounting shaft sections (19) and the seat surfaces (9a, 11a) of the end windings (9, 11) are in contact with the receiving surfaces (17a) of the seats (17), there is a gap or no gap between the mounting shaft sections (19) and the expanded-diameter sections (21) of the seats (5) for the coiled spring, and so that, in a state in which the seat surfaces (9a, 11a) of the end windings (9, 11) are in contact with the receiving surfaces (17a) of the seats (17), the transition sections (13, 15) are located avoiding the expanded-diameter sections (21).
L'invention concerne un ensemble ressort hélicoïdal caractérisé en ce qu'un ressort hélicoïdal et des sièges pour le ressort hélicoïdal, les sièges pour le ressort hélicoïdal étant des éléments de siège, sont enclenchés mutuellement de façon appropriée pour empêcher l'interférence excessive entre les enroulements d'extrémité du ressort hélicoïdal et les sièges pour le ressort hélicoïdal, ce qui permet d'augmenter la durabilité de l'ensemble ressort hélicoïdal. L'invention concerne un ensemble ressort hélicoïdal caractérisé en ce que : un ressort hélicoïdal (3) comporte des enroulements d'extrémité (9, 11) enroulés chacun un tour à un diamètre réduit et comporte des sections de transition (13, 15) dont un diamètre augmente progressivement des enroulements d'extrémité (9, 11) jusqu'à une section de corps (7) ; des sièges (5) pour le ressort hélicoïdal possèdent des sections de siège (17), des sections d'arbre de montage (19), et des sections de diamètre étendu (21), les sections d'arbre de montage (19) possédant une longueur défin |
