摘要： A rail vehicle, such as a locomotive, has at least one undercarriage with one or more wheel sets and an undercarriage frame. A vehicle body, resiliently supported on the undercarriage, has a vertical pivot pin passing through the undercarriage frame for traction linking the vehicle body. A limiting stop is connected to the pivot pin for limiting the vertical motion of the vehicle body relative to the undercarriage frame. The pivot pin has a horizontal through-hole in a downwardly protruding pin segment for supporting the limiting stop. Contact protrusions of the limiting stop protrude from the through-hole on both sides of the pivot pin. In the event of maximum vertical motion, the limiting stop contacts the undercarriage frame from below by way of the contact protrusions. The entrainment of the undercarriage is thus effected with great safety when the rail vehicle is lifted.
