Abstract
A shear-off device for a train coupler comprising a safety ring having an inner periphery formed with a thread for threaded engagement, and further comprising a radially inwards depending shear flange, the shear flange reaching in radial direction from the inner periphery towards the center axis of the safety ring, the shear flange having a flange base adjoining the inner periphery and a flange point reaching radially inside of the inner periphery.
Claims15
A shear-off device for a train coupler, the shear-off device comprising a safety ring in the form of a rotationally symmetric component having a cylindrical web portion defined by an outer periphery and an inner periphery in concentric relation about a center axis, wherein the inner periphery is formed with a thread in an open first or forward end of the safety ring, wherein in an opposite second or rear end of the safety ring a shear flange is formed, the shear flange reaching in radial direction from the inner periphery of the safety ring towards the center axis, the shear flange having a flange base adjoining the inner periphery, and a flange end reaching radially inside of the inner periphery, wherein the shear flange is divided into sections separated by slots that extend in radial direction from the flange end towards the flange base.
A shear-off assembly for a train coupler, comprising a shear-off device, the shear-off device comprising a safety ring in the form of a rotationally symmetric component having a cylindrical web portion defined by an outer periphery and an inner periphery in concentric relation about a center axis, wherein the inner periphery is formed with a thread in an open first or forward end of the safety ring, wherein in an opposite second or rear end of the safety ring a shear flange is formed, the shear flange reaching in radial direction from the inner periphery of the safety ring towards the center axis, the shear flange having a flange base adjoining the inner periphery, and a flange end reaching radially inside of the inner periphery, wherein the shear flange is divided into sections separated by slots that extend in radial direction from the flange end towards the flange base, wherein a disc-shaped counterpressure means is formed with a bevelled periphery that is adapted angularly to be pretensioned in close contact between the bevel of the counterpressure means and forward-facing sides of the shear flange sections.
