Abstract

A wheelset guide for a rail vehicle, which has a bogie frame, includes at least one longitudinal support, and includes a wheelset bearing for a wheelset of the rail vehicle, wherein the wheelset bearing is connected to the bogie frame and includes a rocker that is pivotably attached to the bogie frame via an elastic rocker bearing, and a pin guided by the rocker bearing, where the bogie frame forms a receptacle for the rocker bearing, which is configured such that the force is introduced into the bogie frame via the rocker bearing itself, and the rocker bearing is positioned in the receptacle in order to improve the strength and stability of the attachment of the rocker to the bogie frame or to the longitudinal support with an open profile.

First claim

The invention claimed is:

1. A wheelset guide for a rail vehicle, comprising:
a chassis frame of a bogie and having at least one longitudinal support; and
a wheelset bearing for a wheelset of the rail vehicle and having a rocker with the outer side face, said wheelset bearing being connected to the chassis frame in a sprung manner via a spring element;
wherein the rocker of the wheelset bearing is pivotably attached to the chassis frame via an elastic rocker bearing encased by a sleeve, and via a pin which passes through said elastic rocker bearing, the pin having an outer side face substantially aligned with the outer side face of the rocker, the elastic rocker bearing extending substantially over an entirety of a central portion of the pin;
wherein the chassis frame forms a receptacle for the rocker bearing, said receptacle being configured such that a transfer of force into the chassis frame occurs via the rocker bearing itself and such that the rocker bearing is positioned in the receptacle.

2. The wheelset guide as claimed in claim 1 , wherein the receptacle at least partly surrounds the rocker bearing.

3. The wheelset guide as claimed in claim 1 , wherein the receptacle is configured as a cylindrical opening in the at least one longitudinal support.

4. The wheelset guide as claimed in claim 2 , wherein the receptacle is configured as a cylindrical opening in the at least one longitudinal support.

5. The wheelset guide as claimed in claim 3 , wherein the at least one longitudinal support has an I-shaped profile.

6. The wheelset guide as claimed in claim 3 , wherein a transfer of force into the at least one longitudinal support occurs via at least one contact section of a contact surface between the elastic rocker bearing and the receptacle.

7. The wheelset guide as claimed in claim 5 , wherein a transfer of force into the at least one longitudinal support occurs via at least one contact section of a contact surface between the elastic rocker bearing and the receptacle.

8. The wheelset guide as claimed in claim 1 , wherein the elastic rocker bearing comprises a rubber-metal bush.

9. The wheelset guide as claimed in claim 1 , wherein a flow of force from the wheelset bearing into the chassis frame runs via the rocker of the wheel set bearing, the pin, the elastic rocker bearing and the receptacle.

10. The wheelset guide as claimed in claim 9 , wherein the pin has a central section which is held in the elastic rocker bearing and at least one end section for attachment to the rocker;
wherein a transfer of force from the rocker into the pin occurs via the at least one end section of the pin; and
wherein a transfer of force from the pin into the elastic rocker bearing occurs via the central section of the pin.

11. The wheelset guide as claimed in claim 1 , wherein the rocker includes a forked section for receiving two end sections of the pin.

12. The wheelset guide as claimed in claim 11 , wherein the end sections of the pin are connected to the forked section of the rocker in a torsionally rigid manner.

13. The wheelset guide as claimed in claim 11 , wherein the forked section of the rocker laterally surrounds the chassis frame at least partly.

14. The wheelset guide as claimed in claim 12 , wherein the forked section of the rocker laterally surrounds the longitudinal support at least partly.

15. The wheelset guide as claimed in claim 1 , wherein the elastic rocker bearing is pressed into the receptacle.

16. The wheelset guide as claimed in claim 1 , wherein the elastic rocker bearing is glued into the receptacle.

17. The wheelset guide as claimed in claim 1 , wherein the pin has a longitudinal axis and the wheelset bearing has a wheelset axis, and wherein the longitudinal axis and the wheelset axis are arranged in parallel.

18. The wheelset guide as claimed in claim 1 , wherein the spring element is a primary spring of the rail vehicle.

19. The wheelset guide as claimed in claim 1 , wherein the wheelset is mounted in the wheelset bearing.
