Shock-absorbing coupler head for a coupling arrangement

Abstract

A coupler head for a coupling arrangement is shown, which coupler head includes a coupler head housing () extending in a longitudinal direction from a first end (), attachable to a drawbar, to a second end (), which is arranged to carry a coupling interface between coupled rail vehicles, which coupler head housing houses mechanical coupling components () 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 (') 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 (′) for a predetermined folding of the coupler head housing.
