Abstract

A double-jointed coupling includes a carrier ring with an internal tooth arrangement, a hollow pinion shaft connected to the internal tooth arrangement of the carrier ring, and an intermediate shaft with a coupling tooth arrangement for engagement in the internal tooth arrangement. The coupling tooth arrangement is constructed on the intermediate shaft such as to enable passage of the intermediate shaft through the hollow pinion shaft for passage through the hollow pinion shaft. A thrust ring is arranged on the intermediate shaft in a region of the coupling tooth arrangement and constructed for passage through the hollow pinion shaft.

First claim

What is claimed is:

1 . A double-jointed coupling, comprising:
a carrier ring including an internal tooth arrangement; a hollow pinion shaft connected to the internal tooth arrangement of the carrier ring; an intermediate shaft including a coupling tooth arrangement for engagement in the internal tooth arrangement, said coupling tooth arrangement constructed on the intermediate shaft such as to enable passage of the intermediate shaft through the hollow pinion shaft; a sealing element arranged on an external face of the thrust ring; and a thrust ring arranged on the intermediate shaft in a region of the coupling tooth arrangement and constructed for passage through the hollow pinion shaft.

2 . The double-jointed coupling of claim 1 , wherein the coupling tooth arrangement is integrally constructed with the intermediate shaft.

3 . The double-jointed coupling of claim 1 , further comprising a sealing element arranged at an internal face of the thrust ring and constructed to fix the thrust ring to the intermediate shaft.

4 . The double-jointed coupling of claim 1 , wherein the thrust ring is constructed for axial support on the hollow pinion shaft.

5 . The double-jointed coupling of claim 1 , wherein the carrier ring is releasably connected to the hollow pinion shaft.

6 . The double-jointed coupling of claim 1 , wherein the carrier ring is integrally constructed with the hollow pinion shaft.

7 . The double-jointed coupling of claim 1 , wherein the intermediate shaft is integrally constructed with a lamellar flange.

8 . The double-jointed coupling of claim 1 , wherein the Intermediate shaft is embodied in the form of a hollow shaft.

9 . A bogie of a rail vehicle, said bogie comprising:
a double-jointed coupling as set forth in claim 1 ; a traction motor connected to the double-jointed coupling so as to transmit torque to the double-jointed coupling; and a gear mechanism connecting the double-jointed coupling to an axle and/or a wheel so as to transmit torque.

10 . A rail vehicle, comprising:
a wagon body; and a bogie fixed to the wagon body, said bogie being constructed as set forth in claim 9 .

11 . An industrial application, comprising:
a double-jointed coupling as set forth in claim 1 ; and a drive unit connected to an output unit so as to transmit torque via the double-jointed coupling.

12 . A method for assembling a double-jointed coupling, said method comprising:
fitting a thrust ring to an Intermediate shaft; introducing the intermediate shaft through a hollow pinion shaft; fitting at least one sealing element and a securing element to an external face of the thrust ring; fixing a carrier ring having an Internal tooth arrangement to the hollow pinion shaft for engagement with a coupling tooth arrangement of the Intermediate shaft.
