Coupling system for a rail vehicle, comprising coupling halves (4, 5) which can be coupled to one another, can be attached in each case to a wagon structure of the rail vehicle, and in each case comprise the following features: - in each case one coupling rod (9, 10) with a coupling portion (7, 8); - in each case one bearing block (2, 3), on which the coupling portion (7, 8) is mounted on one side via the coupling rod (9, 10); - in each case one centring shoulder (29, 29') which is provided on the coupling portion (7, 8); - in each case one first positively locking surface (22, 22') which is provided on the coupling portion (7, 8) and faces the bearing block (2, 3); - in each case one second positively locking surface (23, 23') which is supported against the bearing block (2, 3) and faces the first positively locking surface (22, 22'); and wherein, a) in the case of at least one coupling half (4, 5), the coupling rod (9, 10) is mounted on the bearing block (2, 3) such that it can be moved at least in its longitudinal axis, and at least one elastic element (17, 17') is arranged between the coupling rod (9, 10) and the bearing block (2, 3) in such a way that it counteracts at least a longitudinal displacement of the coupling rod (9, 10) in the direction of its coupling portion (7, 8); and, b) in the case of at least the other coupling half (4, 5), at least one further elastic element (17, 17') is arranged between the bearing block (2, 3) and the second positively locking surface (23, 23') in such a way that it counteracts at least a displacement of the second positively locking surface (23, 23') in the direction of the bearing block (2, 3); and c) the coupling system additionally comprises at least one sleeve joint, which has a complementary positively locking surface with respect to each of the positively locking surfaces (22, 22', 23, 23') and which, furthermore, has at least one centring surface which is complementary with respect to centring shoulders (29, 29') of the two coupling halves (4, 5). - in each case one coupling rod (9, 10) with a coupling portion (7, 8);
