The present invention relates to an elastic coupling (1) between rail vehicle wagons, comprising: an end support (2) or curved head (8) in turn comprising a screwed straight area (5), an intermediate deformation area (6) and an end coupling area (7), the end (8) of the coupling area (7) being curved, an end support (3) or straight head (8) in turn comprising a screwed straight area (5), an intermediate deformation area (6) and an end coupling area (7), the end (8) of the coupling area (7) being straight, and an enclosing case (4) covering the end coupling area (7) of the support (2) and the end coupling area (7) of the support (3),
such that the supports (2) and (3) are attached to one another by draw connection means and by elastic elements. The walls of the intermediate area 6 of the support 2 are curved inwards, and the walls of the intermediate area 6 of the support 3 are curved outwards.

This articulation device for an articulated vehicle comprises a first shackle (14), a second shackle (16), and an articulation joint (18) comprising a first articulation member (20) comprising a single first section (52) and a second articulation member (22) comprising a single second section (60). The first section (52) and the second section (60) are rotatable relative to each other; the first shackle (14) is connected to the first articulation member (20) and the second shackle (16) is connected to the second articulation member (22). The second articulation member (22) comprises a single connecting member (66) through which the second section (60) is connected to the second shackle (16), the connecting member (66) being adapted to adjust the position of the second section (60) relative to the second shackle (16) along a longitudinal axis (X2-X2) and along a transverse axis (Y2-Y2).

A claw system for mechanical coupling a railcar mover to a railcar is disclosed herein. The claw assembly may comprise a set of arms and a set of claws each mounted on the interior side of one of the set of arms. When a railcar adjacent to a railcar mover on a set of tracks is positioned within a proximity of the railcar mover, the claw assembly may be utilized to grasp the air hose of the adjacent railcar. For example, the set of arms may be attached to the railcar mover via a motorized rail upon which the set of arms may be configured to move axially toward each other in a direction perpendicular to the tracks, thereby causing the claws to move toward each other and close around the air hose of the adjacent railcar. The claws may include openings configured to grasp the air hose.

A chain of semi-trailer vehicles is intended to be articulated to a main vehicle. Each semi-trailer vehicle includes a body and a single bogie supporting the body, known as a trailer bogie. The bodies of the semi-trailer vehicles are successively articulated to one another from a first semi-trailer vehicle of the chain by a separate inter-body joint. Each inter-body joint is carried by one end of each semi-trailer vehicle connected to a following vehicle. Each inter-body joint is articulated along a vertical pivot axis. Each trailer bogie of a body carries an inter-body joint arranged longitudinally with respect to the body so that the bogie axis and the interconnection axis are offset.
