Recovery characteristic of the NiTi shape memory alloy material after load unloading is closed, Lai Shixian pressure loading acts on oneself of rear
It is dynamic to repair, it is keeping and under conventional safety device performance unanimous circumstances, is realizing substantially drop weight.
Background technique
Commercial vehicle front underrun protection device is made of protection crossbeam and connecting bracket, in addition to meeting some size requirements
Outside, the active force in reply protection direction has enough barrier forces, and especially protection crossbeam answers transverse property with higher.Often
The front lower portion protection crossbeam of rule is to be fabricated by steel plate through processes such as roll bending, welding, and internal usually welding stiffening plate is come
Guarantee whole anti-bending strength and reliability, therefore exist and expect thick redundancy have biggish drop weight space.
Summary of the invention
The present invention proposes to protect assembly under a kind of skeleton commercial vehicle of memorial alloy, can be to be parallel to that vehicle is horizontal, the longitudinal axis
Active force enough barrier forces is provided, reduce the risk that other vehicles pierce its bottom.Due to being closed using NiTi shape memory
Gold, glass fibre and casting aluminium material, in conjunction with space frame design concept, compared with the roll bending steel assembly of traditional handicraft, light weight
Change significant effect.
The present invention protects the anti-bending strength of crossbeam as mesh for the functional characteristics of commercial vehicle front lower portion protection assembly to be promoted
Mark, using space frame structure designing technique, NiTi shape memory alloy material, glass mat, cast aluminium bracket are combined,
Devise skeleton commercial vehicle front lower portion protection assembly.Wherein, coating of the glass mat as protection crossbeam, plays envelope
With the effect of fixing internal skeleton；NiTi shape memory alloy material is made through cutting, punching press, heat treatment, shape training, welding
Protect the inside support frame of crossbeam；Glass fiber cloth laminates and NiTi alloy support frame are fixed by resene glue sticking.
The left and right both ends of side Glass fiber cloth laminates are connected with cast aluminium bracket by bolt respectively, constitute lower portion assembly.This
Kind assembly structure has good anti-bending strength, and special using reply of the NiTi shape memory alloy material after load unloading
Property, Lai Shixian pressure loading acts on the automatic rebounding reparation of rear protecting crossbeam, assembly reduction by 40% of the weight compared with same level vehicle
More than.The skeleton front lower portion protection assembly of similar memorial alloy does not appear in commercial vehicle component structural design field.
The present invention includes Glass fiber cloth laminates and NiTi marmem support frame, NiTi marmem
The upper and lower surfaces of support frame cover Glass fiber cloth laminates, and Glass fiber cloth laminates pass through resene glue and support frame
Realization is adhesively fixed, and constitutes protection crossbeam.Protection crossbeam two sides are connect by screw bolt and nut with cast aluminium bracket, and it is total to constitute protection
At.The NiTi marmem support frame is by being thin by M font NiTi alloy bracket and groined type NiTi alloy
Plate is constituted, and M font NiTi alloy bracket is welded on groined type NiTi latten, forms single layer skeleton structure, single layer skeleton
Structure, which is successively welded, forms NiTi marmem support frame.
Upper and lower surfaces covering of the Glass fiber cloth laminates as protection crossbeam；
The M font NiTi alloy bracket is through wire cutting, punching press, heat treatment, shape training manufacture, the well
Font NiTi latten is manufactured through wire cutting technology.
Cast aluminium bracket is realized by the side of screw bolt and nut and Glass fiber cloth laminates and is connected and fixed, and it is total to constitute protection
At.
The present invention can be used for designing the protection below front lower portion, rear lower and the side of commercial vehicle and prevent piercing device.
Glass fiber cloth laminates can according to rigidity and intensity requirement, using different performance grade, different fiber directions,
The glass mat of different-thickness.
Through wire cutting, punching press, heat treatment, shape training manufacture M font NiTi alloy bracket, play support, energy-absorbing,
And the function of shape is automatically replied, it is each laminated to play connection for the groined type NiTi latten manufactured using wire cutting technology
The effect of golden bracket, M font NiTi alloy bracket and groined type NiTi latten weld to form single layer skeleton structure, by single layer
Skeleton structure is successively welded into NiTi marmem support frame.
Beneficial effects of the present invention:
It can substitute and protect assembly under the commercial vehicle of traditional heavy wall metal structure form, before having same bearing capacity
It puts, realizes lightweight, and automatically reply original shape after pressure loading unloading using NiTi marmem, promoted
Protect the service life of assembly.The stability of load bearing process middle cross beam is kept using Glass fiber cloth laminates；Utilize NiTi shape
Memorial alloy support frame Promoting Layered Buffer energy-absorbing is horizontal, and reduces shock loading damage caused by vehicle and occupant；And NiTi
Marmem can automatically return to the shape of initial training after unloading, and then compressive deformation position is supported to return back to just
Beginning state.In addition, the application of light material and space frame, which design, reduces overall weight also significantly, be conducive to the light of vehicle
Quantitative design.M word in the material type and intensity rank and NiTi marmem support frame of Glass fiber cloth laminates
Angle at the top of shape NiTi alloy bracket, the layout density of bracket can carry out completely new optimization design according to different bearer function,
Can be used for designing below front lower portion, rear lower and the side of commercial vehicle it is anti-pierce device, there is fabulous scalability and application
