9. Device for the transmission of tensile force according to one of claims 1 to 8, characterized in that that the pivot pin (1) has a predetermined transverse play (ft) in a manner known per se in the transverse direction of the vehicle.

In known traction transmissions, the pivot pin, which is fixedly arranged in the main frame, protrudes with its free lower end in a bearing housing, between this and the outer surface of the lower Trunnion end two annular, axially spaced rubber springs are provided. In this embodiment, parts of the annular rubber spring are in compression, but other parts are more disadvantageous Way stressed by thrust, which leads to premature wear of the rubber spring. Furthermore, this design requires the springs arranged around the outside of the pivot pin a certain amount of space.

It is the object of the invention specified in claim 1 to provide a resilient transmission of tensile force between To create bogie and the vehicle main frame that is practically not subject to wear and reduces the space required.

To solve this problem, it is proposed to use the pivot pin in the area of its free end to provide a recess open towards this end, in which a disk-shaped spring with its Axis is arranged in the vehicle longitudinal direction.

By this measure, the object of the invention is achieved in an advantageous manner because the spring now only claimed under pressure and without any special space requirement within the pivot pin with skilful use of the inner area of the same, which is not decisive for the strength is housed.

A development of the invention is that the spring in a known manner as a Rubber washer is formed with biconcave end faces. Besides the advantage of only having one get along with such a spring, thereby simplifying and thus making the construction cheaper results, guarantees the execution of the loosely inserted biconcave rubber disc spring great damping and thus particularly good running properties of the rail vehicle.

Other advantageous refinements of the invention can be found in the further subclaims.
