摘要

An elastic device apt to allow the assembly of simple traction automatic hooks in railway vehicles, particularly of the discontinuous traction type, characterized in that it comprises, for each of the two end testeras of the vehicle, two groups (4, 11) of rubber annular springs arranged in series along the longitudinal axis of the vehicle, one of such groups (11), arranged at a later time between a rear plate (12), which reacts against fixed supports (12a) integral with the frame (13) of the vehicle and an anterior plate (9), which can move inwards and is previously contrasted by fixed supports (9a) integral with the frame, the springs of the previous group (4) being in turn comprised between a rear plate (5), which is supported on the front plate (9) of the other group (1) of springs and an anterior plate (3) that can move inwards and is previously contrasted by (4a) fixed supports (3a) integral to the frame: in the aforementioned front plate (3) of the external group (4) being supported a joint member (2) attached to the automatic coupling device (1) and attached, by an axial brace ( 7) to the rear plate (5) of the same group so as to compress only the springs of the external group (4) when the vehicle is subjected to tensile forces; the compression efforts being transmitted directly from the automatic coupling device (1) both groups of springs (4, 11) through the front plate (3) of the external group.
