Description
Technical field
This utility model is related to automobile component field and in particular to a kind of strong wearability automobile top cover curb girder assembly.
Background technology
In the top cover position of automobile frame, typically there are curb girder and two kinds of supporting constructions of crossbeam.Wherein, curb girder is to anti-wear performance
Requirement higher because when vehicle accelerate, slow down or turn round when, curb girder all can be subject to rubbing and top cover or side cover between
Wiping power, if the wearability of curb girder is bad, it will face curb girder frequently change, car inspection and repair increased frequency, security performance decline
The problems such as.Therefore, develop the problem that a kind of automobile top cover curb girder assembly with strong wearability is a great practical value.
Utility model content
For the problems referred to above, this utility model provides a kind of strong wearability automobile top cover curb girder assembly.
The purpose of this utility model employs the following technical solutions to realize：
A kind of strong wearability automobile top cover curb girder assembly, is characterized in that, including outer support portion, integral support portion, matrix and 2
Low level abrasion body, the both sides of outer support portion and the discrete matrix of integral support portion；Described outer support portion and integral support portion all include bottom
With the extension on bottom, the width of described extension is more than the width of bottom；The outside in described outer support portion is laid with first
Carbon fluororubber layer, the upper surface of described extension is provided with the composite bed of one layer of ethylene propylene diene rubber and high-carbon steel；Described extension
The high spot in portion is round and smooth curved end；2 described low level abrasion bodies are arranged on matrix, and are located at outer support portion and interior
Between support part；The upper surface of described low level abrasion body is provided with the second carbon fluororubber layer, and the upper surface of the second carbon fluororubber layer
It is less than the upper surface of described composite bed higher than the lower surface of described composite bed.
Preferably, the upper surface of described second carbon fluororubber layer is located at 1/2 thickness of described composite bed.
Preferably, the section axis of described low level abrasion body is overlapped with the section axis of matrix.
The beneficial effects of the utility model are：Extension is conducive to reducing the frictional force that per unit contact area is subject to, and arc
Being designed with of shape end face is worn and torn beneficial to less corner angle；It is provided with the composite bed of ethylene propylene diene rubber and high-carbon steel, be conducive to improving
Anti-wear performance when automobile accelerates, slows down, and the first carbon fluororubber layer mainly can improve the anti-wear performance of curb girder when automobile turns round；
When composite bed abrasion than more serious when, to provide certain wear resistance by the second carbon fluororubber layer, composite bed can be extended complete
The time entirely wearing away.
Brief description
Using accompanying drawing, the utility model is described in further detail, but the embodiment in accompanying drawing is not constituted to of the present utility model
Any restriction, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to following attached
Figure obtains other accompanying drawings.
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is sectional view of the present utility model；
Fig. 3 is position view when top cover curb girder assembly uses.
Reference：Outer support portion -1；Integral support portion -2；Matrix -3；Low level abrasion body -4；Bottom -5；Extension -6；The
One carbon fluororubber layer -7；Composite bed -8；Curved end -9；Second carbon fluororubber layer -10.
Specific embodiment
With the following Examples this utility model is further described.
A kind of strong wearability automobile top cover curb girder assembly as shown in Figure 1-2, including outer support portion 1, integral support portion 2, base
Body 3 and 2 low levels abrasion bodies 4, the both sides of outer support portion 1 and the discrete matrix 3 of integral support portion 2.As shown in figure 3, when using, outward
The upper surface of supporting part 1 and lateral surface, and the upper surface of integral support portion 2 all contacted with automobile top cover.
Outer support portion 1 and integral support portion 2 all include the extension 6 on bottom 5 and bottom 5, and the width of extension 6 is more than bottom
The width in portion 5, this can increase the contact area of supporting part and top cover, reduces the stress of unit area, improves the wear-resisting of curb girder
Property.
The outside in outer support portion 1 is laid with the first carbon fluororubber layer 7, and the upper surface of extension 6 is provided with one layer of ternary second
The composite bed 8 of the third rubber and high-carbon steel.The high spot of extension 6 is round and smooth curved end 9, and this is with respect to traditional corner angle formula
For end face, have the advantages that not allow easy to wear.
2 low level abrasion bodies 4 are arranged on matrix 3, and are located between outer support portion 1 and integral support portion 2.Low level abrasion body
4 upper surface is provided with the second carbon fluororubber layer 10, and the upper surface of the second carbon fluororubber layer 10 is higher than the lower surface of composite bed 8
And it is less than the upper surface of described composite bed 8, the wear and tear section axis of body 4 of low level is overlapped with the section axis of matrix 3.Preferably
Ground, the upper surface of the second carbon fluororubber layer 10 is located at 1/2 thickness of composite bed 8.Composite bed 8 be provided with beneficial to improve automobile
Anti-wear performance when accelerating, slowing down, and when the first carbon fluororubber layer 7 is mainly used in turning round, improve the anti-wear performance of curb girder.Low level
Abrasion body 4 effect be, when composite bed 8 wear and tear than more serious when, the second carbon fluororubber layer 10 is contacted with top cover, by the second carbon
Fluororubber layer 10, to provide certain wear resistance, extends the time that composite bed 8 is worn away completely.
Finally it should be noted that above example is only in order to illustrating the technical solution of the utility model, rather than to this reality
With the restriction of novel protected scope, although having made to explain to this utility model with reference to preferred embodiment, this area general
Lead to it will be appreciated by the skilled person that the technical solution of the utility model can be modified or equivalent, without deviating from this
The spirit and scope of utility model technical scheme.
