Railway vehicle and joint connector thereof

A joint connector, comprising a concave joint and a convex joint, between which a traction force and a compressive force are transmittable, wherein a traction force transmission member is provided between the concave joint and the convex joint to transmit traction force, and/or a compressive force transmission member is provided between the concave joint and the convex joint to transmit compressive force, the traction force transmission member and the compressive force transmission member are detachably mounted and positioned in the concave joint;

• wherein the convex joint is connected to the concave joint by a joint bearing, a traction pin is provided in the joint bearing and is configured to transmit the traction force to the traction force transmission member;
• wherein the traction force transmission member is provided with a support portion matching with an outer periphery of the traction pin, and an end portion of the traction pin is arranged on the support portion;
• wherein the traction force transmission member has an outer periphery fitted with an inner cavity of the concave joint to allow the traction force transmission member to be radially positioned in the inner cavity of the concave joint after being fitted;
• and
• wherein the traction force transmission member comprises an annular main body and a support claw projecting from a surface of the annular main body, the support portion is formed on the support claw, the annular main body has an outer periphery fitted with the inner cavity of the concave joint.
