For example, bolt 250 and related nut 252 can be used for one or more energy absorbing elements 100 are cooperated securely with each brace summer 290.A plurality of stud bolts 260 also can be used for releasably energy absorbing element 100 fastening with relevant brace summer 290.Can select with stud bolt 260 and in correlation energy absorber element 100 the relevant size of corresponding opening 108, make and under the situation that stud bolt 260 does not shirk, to mount and dismount energy absorbing element 100 after the shirking of machanical fastener 250.For such as Figure 14 and embodiment shown in Figure 15, bolt 250 and packing ring 254 can be dismantled, to allow shirking of liner plate (doubler) 114 and correlation energy absorber element 100a, 100c.Nut 252 will preferably keep and related nut fastener 280 secure fit.
For the some embodiments of the present invention such as energy absorber system 20c representative, each energy absorbing element 100 can have elongated substantially rectangular configuration, and it is partly defined by first longitudinal edge 121 and second longitudinal edge 122.See Figure 15 and 16.The first row opening 108 can be adjacent to form with first longitudinal edge 121 in each energy absorbing element 100.The second row opening 108 can be adjacent to form with each second longitudinal edge 122 in each energy absorbing element 100.The third line opening 110 that has plate 112 betwixt can be formed in each energy absorbing element 100 between the first row opening 108 and the second row opening 108.See Figure 15 and 16.
Use for some, energy absorber system 20c can have the soft relatively phase I, the phase III that has the second stage that strengthens energy absorption capability and be designed to absorb the energy of high speed and/or heavier vehicle.The length of energy absorbing element 100d can increase and/or reduce in phase I, to change the amount of the energy absorption in the initial knockout process of vehicle and carriage assembly 40c.
The second stage of energy absorber system 20c can be included in the energy absorbing element 100a that has variable spacing between associated openings 110 and the associated plate 112.For the embodiment shown in Figure 16, the first of each energy absorbing element 100a can comprise the opening 110 with about 1 inch diameter, and the spacing between adjacent apertures 110 centers is about 2 inches.The mid portion of each energy absorbing element 100a can comprise the opening 110 with about 1 inch diameter, and the spacing between adjacent apertures 110 centers is about 3 inches.As a result, the length of the fragment 112a in the first of each energy absorbing element 100a can be about 1 inch.Each fragment 112b can have about 2 inches length in the mid portion of energy absorbing element 100a.
When vehicle initially clashed into carriage assembly 40c, the part of vehicle energy absorbed in the phase I.When destroyer 216 cooperated with energy absorbing element 100a, the amount of the energy that is absorbed by fragment 112a was compared and can be increased with the phase I (energy absorbing element 100d), can remain on one than low value but compare with the energy of fragment 112b absorption.Compare with short fragment 112a, the length increase of fragment or plate 112b causes the deceleration that strengthens.Therefore, along with destroyer 216 moves through the mid portion of each energy absorbing element 100a, can absorb suitable lot of energy.
Along with vehicle impact begins to slow down, needs energy absorption still less stops the part in not affined passenger's vehicle impact.Therefore, the third part of each energy absorbing element 100a or the spacing between the hole in the decline 110 can reduce.For example, fragment 112c can have the length roughly the same with fragment 112a, and perhaps the length of fragment 112c is compared with the length of fragment 112a even can also further be reduced.
For many Vehicular impacts, most energy absorption can occur in stage one and stage two.Yet for very at a high speed and/or heavier vehicle, destroyer 216 can cooperate with the energy absorbing element 100b in the stage three.Use for some, the thickness of the energy absorbing element 100b in the stage 3 can increase considerably.Alternatively, the spacing between the hole 110 in the stage 3 can increase considerably.Instruction of the present invention allows to revise energy absorbing element 100, thereby proposes the deceleration that institute's supply and demand is wanted for the multiple vehicle that multiple speed is travelled, and does not cause the injury to the passenger that is not tied of vehicle.
Use for some, two or more energy absorbing elements 100 can be arranged on second side plate 292 of each brace summer 290.For the embodiment shown in Figure 14, the thickness of energy absorbing element 100a, 100c can change.In addition, the spacing between each opening 110 that forms among each energy absorbing element 100a, 100c and/or the size of opening 110 also can change.
As above mentioned, the present invention allows to reduce the quantity of the machanical fastener that must cooperate or shirk in the replacing process of fracture or broken energy absorbing element 100.As shown in Figure 14 and 15, one or more machanical fasteners without a head or stud bolt 260 can be arranged between each machanical fastener 250.Use for some, liner plate or reinforcement backing 114 can relatively be arranged on the energy absorbing element 100 with second side plate 292 of relevant brace summer 290.Liner plate or reinforcement backing 114 improve the chucking power of associated fasteners 250, and allow the use of stud bolt 260 simultaneously.For some application shown in Figure 13, manyly can be used for each energy absorbing element 100 is cooperated securely with correlation energy absorbent assembly 286 to liner plate (being designated as 114a-114h).Each liner plate 114 preferably includes the corresponding hole 124 of diameter of the associated orifices 108 that forms with longitudinal edge 121,122 along each energy absorbing element 100.The hole 124 that forms in the liner plate 114 can be preferably selected to be and hold bolt 250 and stud bolt 260.
