Device for coupling towing- and tractor drawn vehicles, has indexing elements including retaining elements that co-act with fixing elements integrated with drawbar or attaching part in blocking state when drawbar is in active configuration

摘要

The device has indexing elements for angularly locking a drawbar (10) around a rotation axis (13) against an action of return elements (14) in an active configuration in which fastener elements (11) occupy a low position and are hooked to a towing vehicle. The indexing elements include a locking pedal (17) articulated on an attaching part (12) or the drawbar and provided with retaining elements that co-act with fixing elements (19) integrated with the drawbar or the attaching part in a locking state when the drawbar is in the active configuration.
