ENERGY ABSORBING DEVICE, MORE SPECIFICALLY, PRESENTED IN A FORM OF IMPACT FORCE PROTECTIVE DEVICE FOR TRACK VEHICLES Russian patent published in 2012 - IPC F16F7/12 B61G11/16 

FIELD: mechanical engineering.

SUBSTANCE: invention refers to the energy absorbing device, as well as its use in the quality of impact force protective device for the main frame of track vehicles or in the quality of impact force protective device for the permanent items of equipment, particularly, buffer stop. The energy absorbing device comprises absorbing element (10) and mating member (20). Provided the exceedance of the impact force, applicable to the energy absorbing device, the mating member (20) and absorbing element (10) are shifted in the direction to each other. Simultaneously absorption of at least some part of impact energy, applied to the energy absorbing device, takes place. The mating member (20) constitutes a hollow body, open from one end and situated adjacent to the absorbing element (10) for the purpose of forming at least one energy absorbing section (11), produced out of composite material with fibre filler. Fragments of energy absorbing section (11), produced out of composite material with fibre filler, may get inside a hollow body.

EFFECT: dissipation of high impact energy and energy absorbing device construction simplification.
