Abstract:
1. A linkage for an articulated connection of a coupling rod to a railcar body, wherein the linkage comprises: a base plate connectable to the railcar body in which a through-hole is configured through which a railcar body-side end section of the coupling rod extends; and a drawgear arranged on the railcar body-side end section of the coupling rod and having a front spring plate affixed to the coupling rod in front of the base plate in a longitudinal direction (L) of the coupling rod, and a rear spring plate affixed to the coupling rod behind the base plate in the longitudinal direction (L) of the coupling rock; wherein the drawgear further comprises at least one front spring element made from an elastic material arranged between the base plate and the front spring plate and at least one rear spring element made from an elastic material arranged between the base plate and the rear spring plate; wherein the at least one front spring element and/or the at least one rear spring element engage with the base plate such that the rotational forces transmitted from the coupling rod to the base plate will be conducted at a right angle without slim; and wherein the at least one front spring element exhibits grooves along its periphery, and wherein the base plate exhibits protruding section on its front end face facing the at least one front spring element which create a form-fit engagement with at least some of the grooves configured around the periphery of the at least one front spring element.
