(8) FIG. 5 a detail view V from FIG. 3B.

(9) FIGS. 1A and 1B show a joint arrangement 10 for a truck (not depicted), in particular a Jacobs bogie. FIG. 1A shows the joint arrangement before an accident, in a horizontal regular installation state. FIG. 1B shows the same joint arrangement after an accident, or after an introduction of a force that maximally loaded the deformation elements 12 without causing a destruction of the joint arrangement 10.

(10) The joint arrangement 10 comprises a joint fork part 32 and a joint eye part 34. The joint eye part 34 has a joint eye 40, and the joint fork part 32 has a joint fork 38. Joint fork 38 and joint eye 40 are connected with one another by means of a connecting bolt and form a joint. The joint fork part 32 comprises a first connection plate 16.1, and the joint eye part comprises a second connection plate 16.2. The connection plates 16.1, 16.2 are arranged on a rod 14.1 and 14.2 respectively. At least one connection plate 16, a rod 14, and a cutting tool 18 form a deformation element 12. The connection plates 16.1, 16.2 can be attached to cars (not shown) of a train. A pin 50 is connected with a lower part (not shown) of the truck.

(11) FIG. 2A and FIG. 2B show a vertical longitudinal section through the joint arrangement from FIG. 1A and FIG. 1B. FIG. 2A shows the joint arrangement before an accident, or in a regular installation state. FIG. 2B shows the same joint arrangement after an accident, or after an introduction of force that maximally loaded the deformation elements 12.1, 12.2 without causing a destruction of the joint arrangement 10.

(12) The joint eye 40 is arranged in the joint fork 38, wherein these are connected with one another by means of the joint pin 36. The joint eye 40 is connected in one piece and materially joined with the rod 14.2, and forms the joint eye part 34. The connection plate 16.2 is arranged on the rod 14.2 and with this forms the deformation element 12.2. The joint fork 36 is connected in one piece with the rod 14.1 and forms the joint fork part 32. The connection plate 16.1 is arranged on the rod 14.1 and with this forms the deformation element 12.1. The rods 12.1 and 12.2 are essentially hollow in design.

(13) If the connection plates 16.1 and 16.2 from FIG. 2A move towards each another in the displacement direction 28, in the shown embodiment the connection plate 16.2 is limited in its movement by means of a shoulder of a stop element 24.2 of the joint eye part 34, which shoulder is formed materially connected with the joint eye 40 or the rod 14.2. As is apparent in FIG. 2B, upon displacement by the maximum displacement path 22, which is shown in FIG. 3A, the connection plate 16.2 comes into contact with the shoulder 24.2. If the connection plate 16.2 is in contact with the shoulder 24.2, an additional force introduction into the connection plate 16.2 is introduced directly from the connection plate 16.2 into the shoulder 24.2 or into the rod 12.2.

(14) FIG. 3A and FIG. 3B show a horizontal longitudinal section through the joint arrangement from FIG. 1A and FIG. 1B. FIG. 3A shows the joint arrangement before an accident, or in a regular installation state. FIG. 3B shows the same joint arrangement after an accident, or after an introduction of a force that maximally loaded the deformation elements 12.1, 12.2 without creating a destruction of the joint arrangement 10. A difference in the lengths 52 and 54 is the sum of the two maximum displacement paths 22 of the deformation elements 12.1 and 12.2.

(15) The cutting tools 18 are arranged, in particular bolted tightly, on the connection plates 16.1, 16.2. It is to be learned from FIG. 3A that the cutting tools 18 engage in recesses 56. If the connection plate 16.1 moves in the movement direction 28 (again not drawn here for reasons of clarity), the movement of the connection plate 16.1 is limited by a stop element 24.1 materially connected with the joint fork 36 or the rod 14.1. In contrast to the stop element 24.2 from FIG. 2, the stop element 24.1 is not designed as a shoulder but rather is characterized by a continuously increasing material thickness of the rod 14.1. An increased cutting resistance opposes the cutting tool 18, which cutting resistance limits the movement of the connection plate 16.1. The maximum displacement path 22 of the connection plate 16.1 is achieved when the cutting resistance is approximately so great that, even in an accident situation, the force introduction into the connection plate is not sufficient to lift an additional chip off of the rod 12.1. The force introduction from the connection plate 16.1 into the rod 12.1 also takes place via the cutting tool 18 after the displacement of the connection plate 16.1 by the maximum displacement path 22.

(16) As is apparent from FIGS. 2A and 2B in conjunction with FIGS. 3A and 2B, a widening of the rod 12.2 that forms the shoulder 24.2 is formed essentially only in the vertical direction. Furthermore, as is apparent from FIGS. 2A and 2B in conjunction with FIGS. 3A and 2B, a widening of the rod 12.1, said widening forming the transition region 24.1, is formed essentially only in the horizontal direction.

(17) FIG. 4 shows a detail view IV of FIG. 2B, from which it is apparent that the connection plate 16.2 comes into contact with the stop element 24.2 that is designed as a shoulder 26.

(18) FIG. 5 shows a detail view V of FIG. 3B, from which it is apparent that the connection plate 16.1 has a cutting tool 18 that cuts into the material of the rod 14.1 and lifts off a chip 20. The stop element 24.1 has a transition region 30 that runs in a circular arc at least in part in the shown section view. By means of the transition region 30, the cutting resistance is increased continuously so that the movement of the connection plate 16.1 on the rod 14.1 is limited, in particular without coming into contact with the shoulder 26. In a further embodiment, or in the event of a defined introduction of force or impulse, the connection plate 16.1 comes into contact with the transition region 30 and thus a displacement resistance increases.
