Abstract
An energy absorbing device has a rod with a part, suitable for cutting by means of 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.
Claims9
A system to absorb energy from an impact between a first railway car and a second railway car, the system comprising:
- a rod, wherein the rod includes a first end and a second end;
- a body sleeve, wherein the body sleeve is attached to a wall of the second railway car and the body sleeve is configured to receive the first end of the rod;
- and
- cutting tools, wherein the cutting tools are mounted inside the body sleeve and the cutting tools contact the first end of the rod, and absorb kinetic energy of the impact between the first railway car and the second railway car, when the cutting tools cut into the rod as the rod moves through the body sleeve;
- an angular guiding part of the rod, wherein the angular guiding part includes a surface inclined relative to an axis of the rod;
- a support, wherein a first side of the support is connected to the body sleeve with breakable elements;
- and
- a lug connected to the angular guiding part of the rod and pivotally attached to the support.
