Automatic coupling buffer has a central rail, 2004.

摘要

The invention relates to an automatic coupling to the central buffer type willison for vehicles on a rail with a hitching head (1) having, on its front face, two claws of coupling (2, 3) and a pocket of coupling (4) located between the claws of a bolt (5, 5 ′) being provided, that - c may be introduced into the bag of coupling (4) by means of a gear of the latch (6) and then pressing on the lock of the other coupling head, respectively, when the coupling heads are coupled together, while maintaining the claw coupling of the other coupling head in the pocket of coupling. In order to allow the uncoupling and the discharge in the lock by a simple actuation of the rotary lock (6) is provided a lever of the discharge (15) actuated by the gear of the lock to the discharge of the lock, said lever connected to the other respective coupling head (1 ′), moving the latter against the coupling head (1) during the actuation of the rotary lock (6) and releasing after actuating the bolts (5, 5 ′).
