Abstract

The invention relates to a universal double-jointed coupling (1) for railway vehicles with two joint levels (20, 21). Said coupling (1) comprises two coupling joints which are interconnected via a shaft (5) that is surrounded by a hollow pinion shaft (6) in order to transmit torque by means of said hollow pinion shaft (6). One joint level (20) is assigned to a coupling joint (2) encompassing a crowned gear (22) that has angular and axial compensation capability while the other joint level (21) is associated with a torsion-proof, flexible coupling joint (3). The aim of the invention is to ensure that coupling elements can be replaced easily and freely without any problem in the area of the coupling joint encompassing the crowned gear.; Said aim is achieved by providing the coupling joint (2) encompassing the crowned gear (22) with a removable internally geared sleeve (7) and a removable matching externally geared coupling hub (23). A final area of the shaft (5), which is embodied as an intermediate shaft, is connected to the removable coupling hub (23) while the hollow pinion shaft (6) is fastened to the outer wall of the sleeve (7) outside the removable sleeve (7).

Description

technical field [0001] The invention relates to a double joint joint (Doppelgelenkkupplung) with two articulation planes for rail vehicles, which has two clutch joints (Kupplungsgelenk) for passing through a pinion Hollow shafts for torque transmission, connected to each other via a shaft surrounded by a pinion hollow shaft, one of the articulation planes is assigned to a clutch joint with crowned teeth with angular and axial compensation, and the other articulation The plane is equipped with a torsionally rigid, flexurally elastic clutch joint. Background technique [0002] Conventional gear couplings with crowned teeth are used for torque transmission and are used to connect drive shafts and driven shafts in order to compensate axially parallel, axial or angular offsets that occur between the two shafts . [0003] A related drive unit is described in document EP 0878 368 A1, in which each a gear coupling with crown teeth is formed from two identical hinges, wherein there...
