Abstract
An energy absorbing device has a rod with a part, suitable for cutting by surrounding cutting tools mounted in a body sleeve and oriented to the inside. In addition, the rod has an angular guiding part passing into the part suitable for cutting and is pivoted in a support, wherein the body sleeve with the attached cutting tools is connected by breakable elements with the support.
Claims20
A device effective to absorb energy of impacts of railway cars, the device comprising:
- a rod with a part suitable for being cut,
- cutting tools mounted in a body sleeve and oriented to the inside thereof,
- the rod having an angular guiding part with a surface inclined relative to an axis of the rod,
- wherein the angular guiding part of the rod is connected with a lug pivotally attached to a support, and
- the body sleeve is connected to the support with breakable elements, in which the angular guiding part is sized and shaped so that when the rod moves toward the support, the angular guiding part is effective to guide the cutting tools toward the part of the rod suitable for being cut for alignment therewith.
A device for absorbing energy of impacts of railway cars, the device comprising:
- a rod with a part suitable for being cut,
- cutting tools mounted in a body sleeve and oriented to the inside thereof,
- the rod having an angular guiding part with a surface inclined relative to an axis of the rod,
- wherein the angular guiding part of the rod is connected with a lug pivotally attached to a support, and
- the body sleeve being connected to the support with breakable elements and in which a surface of the angular guiding part is inclined at an angle (α) within the range from 7° to 30° relative to the axis of the rod.
A device for absorbing energy of impacts of railway cars, comprising:
- a rod with a part suitable for being cut,
- cutting tools mounted in a body sleeve and oriented to the inside thereof,
- the rod having an angular guiding part with a surface inclined relative to an axis of the rod,
- wherein the angular guiding part of the rod is connected with a lug pivotally attached to a support, and
- the body sleeve is connected to the support with breakable elements in which the hardness of a surface layer of an initial region of the angular guiding part furthest from the part suitable for being cut is greater than the difference in the hardness of the cutting tools and the hardness of the part suitable for being cut.
