Articulated assembly of two links, and associated removal chain
Disclosed is an articulated assembly (10) of two links (100, 101, 102) for a ballast removal chain (8), a first (101) of the two links (101, 102) comprising a single-piece member (101') having two flanges (110a, 110b) which are parallel to one another and each of which has a through-hole (111), a second (102) of the two links comprising a single-piece member (102') comprising a guide flange (120) that is inserted between the two parallel flanges (110a, 110b) of the first link (101), the guide flange (120) being penetrated by a guide hole (112), the articulated assembly (10) further comprising a hinge pin (160) that is inserted into the guide hole (112) and the through-hole (111) in each of the two parallel flanges (110a, 110b). The guide hole (112) is reinforced by a bushing (113) designed to receive the hinge pin (160) and rotatingly guide the hinge pin (160) relative to the single-piece member (102') of the second link (102). The through-hole (111) in one (110b) of the two parallel flanges comprises a flat portion (105) cooperating with a flat section (161) of the hinge pin (160) so as to prevent the hinge pin (160) from rotating relative to the single-piece member (101') of the first link (101).
