  • Publication number: 20230365168
    Abstract: An energy dissipation device is shown in connection with its implementation in train couplers. The energy dissipation device comprises axially compressible, irreversibly deforming steel elements arranged in a housing and axially pre-tensioned between a compression means and a counter-pressure means. In case of an impact, the compression means is moving in sliding contact with the inside wall of the housing to provide axial compression of the energy absorbing elements while preserving the integrity of the housing.
