The knuckle 01 of the traditional articulated coupler is provided with a knuckle upper traction table 011, a knuckle lower traction table 012 and a lock surface 013, wherein the knuckle upper traction table 011 upwards projects out of the top surface of the tail of the knuckle 01, the knuckle lower traction table 012 downwards projects out of the bottom surface of the tail of the knuckle 01, and the lock surface 013 is arranged on the side surface of the tail of the knuckle 01.
The hook body 02 of the conventional articulated coupler is provided with an upper hook traction table 021 and a lower hook traction table 022, the upper hook traction table 021 extends downwards into a head inner cavity of the hook body 02, and the lower hook traction table 022 extends upwards into the head inner cavity of the hook body 02.
When the coupler knuckle 01 and the coupler body 02 are connected, one side surface of the coupler knuckle upper traction table 011 contacts with one side surface of the coupler body lower traction table 022, one side surface of the coupler knuckle lower traction table 012 contacts with one side surface of the coupler body lower traction table 022, and the lock surface 013 of the coupler knuckle 01 contacts with the hook lock 03.

The inventor analyzes that the reasons of low reliability and short service life of the traditional articulated coupler are as follows: the intersection of the bottom surface of the pulling platform of the knuckle 01 and the locking surface 013 forms a stress concentration area, and in addition, the locking surface 013 is a main stress surface of the lock tongue (the locking force of the hook lock 03 acts on the locking surface 013), which causes the pulling platform of the knuckle 01 to be subjected to a large force and, correspondingly, the pulling platform of the hook body 02 which is in contact with the pulling platform of the knuckle 01 to be subjected to a large force, so that the pulling platform of the knuckle 01 and the pulling platform of the hook body 02 are easily broken.
Therefore, the inventor changes the structure of the traction table of the coupler knuckle on the basis of the traditional articulated coupler to form a novel coupler knuckle, and in addition, the utility model also provides an articulated coupler comprising the novel coupler knuckle and a rolling stock comprising the articulated coupler
