Linkage for connecting a railcar body-side end region of a coupling rod in an articulated manner to a railcar body

A linkage for articulately connecting an end portion of a coupling rod to a railcar body of a rail-borne vehicle defining a longitudinal direction, said coupling rod defining a longitudinal axis and being movable between a neutral position wherein said longitudinal axis thereof is coincident with said longitudinal direction of said rail-borne vehicle and a deflected position, the linkage comprising:

• a bearing block fixedly connectable to said railcar body;
• a base plate coupled to said bearing block;
• said base plate having a first side facing toward said railcar body and delimiting a first region extending toward said railcar body;
• said base plate having a second side facing away from said railcar body and delimiting a second region extending away from said railcar body;
• said base plate having a through opening formed therein for accommodating said end portion of said coupling rod extending therethrough and into said first region;
• a push/pull assembly including a first support element arranged in said first region between said base plate and said railcar body;
• and, a second support element arranged in said second region facing toward said second side of said base plate;
• said first side of said base plate and said first support element conjointly defining a first gap and said second side of said base plate and said second support element defining a second gap;
• first and second spring units being disposed in said first and second gaps, respectively;
• said bearing block and said base plate conjointly defining a ball and socket bearing for pivotably supporting said coupling rod on said railcar body;
• said ball and socket bearing conjointly defining a bearing interface whereat said base plate can rotate relative to said bearing block;
• and,
• said end portion of said coupling rod being accommodated and held in said through opening so as to pivot with said base plate as said base plate rotates relative to said bearing block.

• and,
• wherein said bearing block has an end face facing toward said second support element;
• said end face includes a first bearing contact surface formed thereon;
• said second support element has a second bearing contact surface formed thereon;
• and, said first and second bearing contact surfaces conjointly define a predetermined distance therebetween when said coupling rod is in said neutral position and said first and second contact surfaces come into mutual contact engagement when said coupling rod is deflected out of said neutral position in a horizontal and/or vertical direction.
