Patent ID: 7985141

Claim:
Universal double-jointed coupling ( 1 ) for railway vehicles with two joint levels ( 20 , 21 ), which disposes of two coupling joints, which are connected with each other via a shaft, which is surrounded by a hollow pinion shaft ( 6 ) for torque transmission by the hollow pinion shaft ( 6 ), while one joint level ( 20 ) being assigned to a coupling joint ( 2 ) with crowned gear ( 22 ) with angular and axial compensation capability and the other joint level ( 21 ) being assigned to a torsion-proof, flexible coupling joint ( 3 ), characterized by the fact that the coupling joint ( 2 ) with crowned gear ( 22 ) shows a removable internally geared sleeve ( 7 ) and a removable coupling hub ( 23 ) with the corresponding external gearing, while the final area of the shaft ( 5 ), which is embodied as an intermediate shaft, is connected to the removable coupling hub ( 23 ) and the hollow pinion shaft ( 6 ), is fastened to the outer wall of the sleeve ( 7 ) outside the removable sleeve ( 7 ).
