Abstract

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.

First claim

The invention claimed is:

1. A rail vehicle, comprising:
at least one undercarriage having one or more wheel sets and an undercarriage frame resiliently supported on said one or more wheel sets;
a vehicle body resiliently supported on said at least one undercarriage;
a vertical pivot pin passing through said undercarriage frame, said pivot pin traction linking said vehicle body and said undercarriage and allowing said undercarriage to rotate relative to said vehicle body;
said pivot pin having a pin segment projecting downward from said undercarriage frame and a horizontal through-hole formed through said pin segment;
a limiting stop connected to said pivot pin for limiting a vertical movement of said vehicle body relative to said undercarriage frame, said limiting stop being mounted in said through-hole and having contact protrusions projecting on both sides of said pivot pin, said contact protrusions of said limiting stop contacting said undercarriage frame from below in the event of a maximum vertical movement of said vehicle body relative to said undercarriage frame.

2. The rail vehicle according to claim 1 configured as a locomotive.

3. The rail vehicle according to claim 1 , wherein each said contact protrusion has an upward-facing, level contact surface, with which said limiting stop abuts against said undercarriage frame from below in the event of the maximum vertical movement.

4. The rail vehicle according to claim 1 , which comprises securing devices disposed to secure said limiting stop against changes of a position thereof in said through-hole.

5. The rail vehicle according to claim 4 , wherein said securing devices comprise at least one collar on said limiting stop and a securing element connected to said pivot pin, said securing element engaging in a positive form-fit on said collar to secure said limiting stop against displacement.

6. The rail vehicle according to claim 4 , wherein said securing devices comprise at least one arresting surface integrally formed on a periphery of said limiting stop and a securing element connected to said pivot pin and abutting said arresting surface to secure said limiting stop against rotation.

7. The rail vehicle according to claim 1 , wherein at least one of said contact protrusions is formed with a taper toward an outer end thereof.
