The technical scheme that the utility model further limits is: aforesaid train anti-creep endergonic structure device; Said guidance device is cruciform construction; Can give the enough guiding of endergonic structure and support, be unlikely to that guidance device deforms in energy-absorbing, cause energy-absorbing abundant inadequately.
Aforesaid train anti-creep endergonic structure device; Said outside energy-absorbing cover plate is welded by four flanging metal sheets; The disconnected weldering of said inner energy-absorbing plate is connected on the flanging angle of said metal sheet, constitutes stable triangular structure, connects through the section weldering; Can actv. absorb energy, exterior energy causes the energy-absorbing plate distortion at weld not.
Aforesaid train anti-creep endergonic structure device, the said inner energy-absorbing plate that is positioned at said anti-climbing tooth one end is rolled over oriented valgus angle, and the said angle angular range that turns over is 15 °～25 °; When anti-creep endergonic structure device is compressed, inner energy-absorbing plate bending deformation, this dogleg section plays and reduces inner energy-absorbing plate single order flexing power, and the effect of the inner energy-absorbing plate bending deformation of ability positive guide.
Aforesaid train anti-creep endergonic structure device, the outside of said outside energy-absorbing cover plate and said back seat plate junction is welded with restraining plate.
Further; Aforesaid train anti-creep endergonic structure device; Junction at said guidance device and said back seat plate is provided with pilot hole, and said pilot hole shape is consistent with said guidance device shape of cross section, can guidance device be passed through pilot hole; Make guidance device stressed be not participate in distortion, play of the effect of guiding anti-creeper according to preset distortion energy-absorbing.
Further; Aforesaid train anti-creep endergonic structure device, said inner energy-absorbing plate, guidance device and outside energy-absorbing cover plate are processed by aluminium sheet, and the use of aluminum reduces anti-creeper weight; And can guarantee enough intensity, reasonable configuration improves energy absorption ability simultaneously.
This device has following characteristic:
B) the special bending of inner energy-absorbing plate front end is played and is reduced energy-absorbing plate single order flexing power, the effect of guiding energy-absorbing plate distortion;
C) inner energy-absorbing plate is connected with outside energy-absorbing cover plate section weldering, plays guiding bending deformation energy-absorbing function;
D) situation of energy-absorbing plate and outer energy-absorbing cover plate intentional deformation took place in guiding device played and prevents.
The beneficial effect of the utility model is: the utility model is theoretical based on collision energy-absorbing; In conjunction with relevant constructed of aluminium and welding knowledge; As the novel anti-creep endergonic structure of the most basic manufactured materials design-calculated, special dogleg section is set on inner energy-absorbing plate with aluminium sheet, reduces energy-absorbing plate single order flexing power; The distortion of guiding energy-absorbing plate, inner energy-absorbing plate adopt the form of section weldering to be welded on the outside energy-absorbing cover plate.
