Title
(EN) CLEVIS-ENDED SUSPENSION STRUT MANUFACTURED WITHOUT WELDS
(FR) JAMBE DE FORCE À EXTRÉMITÉ DE CHAPE FABRIQUÉE SANS SOUDURES
Abstract
(EN) In accordance with one aspect of the present disclosure, a suspension strut (30) for use on a work machine (1) is provided. The suspension strut (30) may have a forged one piece cylindrical inner housing (32) that includes a hollow rod (36) which forms a circumferential piston (37) at an open end (38) and a lower clevis (39) at a closed end (40) of the hollow rod (36). The suspension strut (30) may further have a forged one piece cylindrical outer housing (31) that includes a hollow barrel (52) having an interior (53) and an exterior surface (54), a closed end (55) that forms an upper clevis (56), an open end (66), and a port (34) on the exterior surface (54) of the hollow barrel (52). Further, the inner and outer housing (32, 31) may be coupled by a disk shaped end cap (65) attached to the open end (66) of the hollow barrel having an inner diameter (68) that is slideably engaged with an outer surface (69) of hollow rod (36).
(FR) Selon un aspect de la présente divulgation, il est prévu une jambe de force (30) pour une utilisation sur un engin de chantier (1). La jambe de force (30) peut présenter un logement interne cylindrique en une seule pièce forgé (32) qui comprend une tige creuse (36) qui forme un piston circonférentiel (37) à une extrémité ouverte (38) et une chape inférieure (39) à une extrémité fermée (40) de la tige creuse (36). La jambe de force (30) peut en outre présenter un logement externe cylindrique en une seule pièce forgé (31) qui comprend un cylindre creux (52) présentant un intérieur (53) et une surface extérieure (54), une extrémité fermée (55) qui forme une chape supérieure (56), une extrémité ouverte (66), et un orifice (34) sur la surface extérieure (54) du cylindre creux (52). En outre, le logement interne et externe (32, 31) peut être accouplé par un capuchon d'extrémité en forme de disque (65) fixé à l'extrémité ouverte (66) du cylindre creux présentant un diamètre interne (68) qui est en prise coulissante avec une surface externe (69) de la tige creuse (36).
