SHOCK-ABSORBING COUPLER Russian patent published in 1998 - IPC

FIELD: mechanical engineering; machine elements; single-acting shock absorbers with plastically deformable elements; railway transport for securing containers filled with explosive cargoes to reduce probability of explosion in case of collision. SUBSTANCE: shock-absorbing coupler includes plastically deformable element 1 to absorb energy of impact held in ears 2, plastically deformable element 1 made in form of strip wound around rectilinear central axle in such way that one half of strip has right-hand winding and other half has left-hand winding. EFFECT: sufficient rigidity at very simple construction, increase tensile strength, complete use of strength of material, enhanced power intensity due to stability of plastic tension of strip. 1 dwg
