SHOCK-ABSORBING COUPLER HEAD FOR A COUPLING ARRANGEMENT

摘要

A coupler head for a coupling arrangement is shown, which coupler head comprises a coupler head housing (6) extending in a longitudinal direction from a first end (6a), attachable to a drawbar, to a second end (6b), which is arranged to carry a coupling interface between coupled rail vehicles, which coupler head housing houses mechanical coupling components (8, 9) effective for automatic coupling to the corresponding components of a connecting coupling arrangement. The coupler head is characterized in that the coupler head housing has at least one notch (11, 11) for a predetermined and primarily axial compression thereof with absorption of energy from a deforming compressive force that is applied to the coupler head in the longitudinal direction thereof. The coupler head has preferably at least one notch ( 11, 11') for a predetermined folding of the coupler head housing.
