The invention relates to a coupling head (1) of an automatic middle buffer coupling (100) having a Willison profile with a large coupling pawl (4) and a small coupling pawl (5). Line coupler (20; 220; 320) which comprises at least one coupling part (21; 21a, 21b) is provided on the coupling head for connecting air lines (18, 18'), in particular braking lines and/or supply lines, between two adjacent car bodies. The invention is characterized in that a first hardening member (8) is provided in the area of the large coupling pawl (4) and a second hardening member (9) complementary to the first hardening member (8) is provided in the area of the small coupling pawl (5). Further, a lever mechanism (30, 31, 32, 33, 34) is provided for causing the coupling part (21; 21a, 21b) of the air line coupler (20; 220; 320) to automatically extend from a first contracting position to a second position in the direction of the coupling plane (T).The lever mechanism (30, 31, 32, 33, 34) can be driven by jointing the second hardening member (9) with the first hardening member (8') which is formed appropriately complementary thereto of a counter-coupling head (1') on coupling the coupling head (1) with the counter-coupling head (1'). |
