A dual coupling (1) comprises two elastic and articulated couplings (2 and 2a) interconnected by a hollow, intermediate shaft (3). Each one of the couplings (2,2a) contain an outer half (4,4a) with a hub (5,5a) from which extend several arms (6). Between them sit more arms (6a) of the intermediate shaft (3). With its arms (6a), the intermediate shaft represents the inner halves of the couplings (2,2a). The ends of the interacting arms (6 and 6a) are interconnected by rubber-elastic connecting rods (7) so that two rows (8) of arms are provided on bolts (10) to the left and right of the arms (6 and 6a) forming a joint plane. Therefore, two joint planes are present. While the connecting rods are connected to the bolts (10) in form closing fashion, the bolts are fixed or articulated in the arms (6 and 6a). One hub ( 5) is connected to a solid axle (15) and the other hub (5a) to a hollow shaft (18). The other hubs, and the axle (15) going through then can deflect angularly relative to each other and can be offset axially relative to each other with gimbal motion without noteworthy return forces originating. The dual coupling (1) is intended in particular for use in rail vehicle axle drives.
