ABSTRACT:
The present invention relates to a hitching device with automatic coupling, applicable in particular to the joining of automotive tractors to their trailers.
This device consists essentially of a fork, in which the pulling member arranged on the tractor engages. Mounted on one of the branches of the fork is a closing arm which can be positioned transversely to the two branches so as to retain the pulling member between them.
This arm is integral with a control lever, upon which the pulling member acts when it is reversed, so as to bring it to the coupling position.
The closing arm is immobilized in this position by a locking device comprising a lock which engages in an indentation of the closing arm and which may be disengaged manually so as to release the closing arm in order to uncouple the trailer.
