Abstract
The present invention discloses a kind of carbon fiber skin structure, and carbon fiber skin sets embedded division, and the embedded division insertion metallic matrix is interior and carbon fiber skin and metallic matrix are integrally fixed by bolt；The bolt is pre-filled with when preparing carbon fiber skin, and the nut coordinated with the bolt is arranged on the inside of metallic matrix.It is an advantage of the invention that：Because fixing bolt is pre-filled with when preparing carbon fiber skin, therefore, the fracture of carbon fiber will not be caused, ensure that the intensity of carbon fiber skin；Relative to other modes, such as carbon fiber skin and pedestal are integrally fixed using the method for riveting, the fracture of carbon fiber is necessarily caused in riveting, reduces the intensity of covering.
Description
Technical field
The present invention relates to a kind of stressed-skin construction, can be applied to locomotive, steamer etc..
Background technology
Existing stressed-skin construction, especially locomotive covering, manufactured mostly using metal, for example steel plate, the material not only weigh
Measure larger, and easily get rusty；When using the covering of this kind of structure on high ferro locomotive, because metal skin and pedestal are using weldering
What the mode of connecing was integrally fixed, be not only easier to get rusty at solder joint, once and solder joint sealing-off, larger loss can be caused；This
Outside, because the density of metal material is larger, cause overall locomotive weight to increase, add fuel consumption, be unfavorable for energy-saving and emission-reduction.
To solve the technical problem, it is thus proposed that a kind of new locomotive stressed-skin construction, such as Chinese Patent Application No.
201410266460.9 disclose " a kind of carbon fiber carriage body construction, including the big plate in compartment, carbon fiber corner fittings and subframe, compartment
The carbon fiber corner fittings of big plate and advance gluing is riveted by steel rivet forms compartment casing, and the big plate in compartment is hardened using sandwich
Structure, the big plate in compartment include upper covering, lower covering, filler and carbon fiber reinforcement one, and filler is located at upper covering and lower covering
Between, carbon fiber reinforcement one is built in filler, and upper covering, filler, lower covering and carbon fiber reinforcement one use structure glue
Bonding, the big plate in compartment is solidified under negative pressure, inner face gluing and the big plate in compartment of carbon fiber corner fittings bond, and steel rivet coats glass
Fluid sealant rivets；Compared with compared to traditional compartment, there is high, the corrosion-resistant and good sealing thermal insulation of light weight intensity
Can, also have the characteristics that surface is neat and artistic, manufacture difficulty coefficient is small, low-carbon environment-friendly.", the patent application employs battenboard
Structure, it is clear that its intensity can not meet the performance requirement of high ferro locomotive.
The content of the invention
In order to solve the above technical problems, it is an object of the invention to provide a kind of stressed-skin construction of carbon fiber, particular technique side
Case is as follows：
A kind of carbon fiber skin structure, it is characterised in that：Carbon fiber skin sets embedded division, and the embedded division is embedded in metal
Carbon fiber skin and metallic matrix are integrally fixed in matrix and by bolt；The bolt is when preparing carbon fiber skin
It is pre-filled with, the nut coordinated with the bolt is arranged on the inside of metallic matrix.
Also include pressure contact portion, the pressure contact portion sets bolt hole, and bolt is screwed in the bolt hole；The pressure contact portion and base
Embedded carbon fiber skin between body；
Embedded division is square type；
Embedded division is Y-shaped；
Embedded division is T-shape；
Embedded division is cross；
Embedded division is round；
Each compartment embedded division shape of locomotive is different.
It is an advantage of the invention that：Because fixing bolt is pre-filled with when preparing carbon fiber skin, therefore, carbon will not be caused
The fracture of fiber, it ensure that the intensity of carbon fiber skin；Relative to other modes, as used the method riveted by carbon fiber skin
It is integrally fixed with pedestal, the fracture of carbon fiber is necessarily caused in riveting, reduces the intensity of covering.
Brief description of the drawings
Fig. 1 is the structural representation that embedded division is square type；
Fig. 2 is that embedded division is round structural representation；
Fig. 3 is the structural representation that embedded division is Y-shaped；
Fig. 4 is the structural representation that embedded division is T-shape；
Fig. 5 is that embedded division is cross structural representation；
Fig. 6 is that embedded division is the structural representation with pressure contact portion.
Embodiment
The present invention is illustrated below in conjunction with the accompanying drawings, and as shown in figs 1 to 6, insertion is set on carbon fiber skin 2 of the present invention
Portion 3, the Y-shaped shown in round, Fig. 3 shown in square type that the cross sectional shape of embedded division 3 can be as shown in Figure 1, Fig. 2, shown in Fig. 4
T-shape, cross etc. shown in Fig. 5, embedded division 3 be embedded in metallic matrix 1 and by bolt 4 by carbon fiber skin 2 with
Metallic matrix 1 is integrally fixed；The bolt 4 is pre-filled with when preparing carbon fiber skin 2, therefore, carbon fiber skin
Filament be wound around on the bolt 4, the fracture of carbon fiber wire can't be caused, and between carbon fiber skin and bolt
Intensity it is more firm compared with other modes such as rivetings, the nut 5 coordinated with bolt 4 is arranged on the inner side of matrix 1.
To ensure the bonding strength between carbon fiber skin 2 and metal base 1, removed between carbon fiber skin 2 and metal base 1
Outside the pulling force that bolt is set, pressure is also add, its structure is：Also include pressure contact portion 6, the pressure contact portion 6 sets bolt hole, spiral shell
Bolt 4 is screwed in the bolt hole；Embedded carbon fiber skin between the pressure contact portion 6 and matrix.
The structure of the embedded division of the present invention is not merely to ensure being reliably connected between carbon fiber skin and metal base,
It is related to carbon fiber skin when being impacted by external force, the shape of embedded division also does corresponding adjustment, as locomotive is transported at a high speed
During row, the outside stressing conditions of permutation locomotive simultaneously differ, and locomotive front portion stress is mainly pressure, and locomotive rear portion then pressure compared with
Small, like this, the stressed-skin construction in the compartment at locomotive rear portion can use the carbon fiber skin structure with pressure contact portion structure, and machine
The embedded division of the anterior stressed-skin construction of car can use rectangle or circular configuration, the embedded division in centre position can use cross or
The structure of Y-shaped and T-shape.It can specifically be considered according to factors such as the length of locomotive, speeds.
In the present invention, the material of metal base can use steel, aluminium, titanium etc..
The structure of the present invention can be applied not only to high ferro locomotive, can also be applied to other high speeds such as automobile, steamer, aircraft
In the device of motion.
