Description
Technical field
The utility model is related to empty iron fields, and in particular to for manufacturing the epidermal structure of empty iron car body.
Background technology
Empty iron, i.e. hanging type aerial monorail traffic system, it is different from subway and tramcar, the track of empty iron on the top,
It is suspended from a kind of track traffic run on overhead rail.Empty iron is a kind of new new energy public transport, and collection city is quick
The advantages of public transport (BRT) and subway, has alleviation traffic congestion, carrying is efficient, at low cost, the construction period is short, no
Occupy many merits such as parking lot, energy conservation and environmental protection.Empty iron reduces empty iron itself weight as far as possible as a kind of underslung track traffic
Amount is always a research emphasis in empty iron field.However existing research direction is mostly reducing empty iron upholstery and load
Direction for making the epidermal structure of empty iron, is all using traditional aluminium alloy in the prior art, strengthens the matter such as aluminium alloy
The relatively light solid metallic materials of amount are made.Although such material is compared to lighter weights such as common stainless steels, so
And metal scope is still fallen within, density is still higher, is unfavorable for the reduction that sky iron is integrally conducted oneself with dignity.
Utility model content
It is hollow to solve the prior art the purpose of this utility model is to provide for manufacturing the epidermal structure of empty iron car body
The problem of iron epidermis quality is larger realizes the purpose for reducing empty iron car body dead weight.
The utility model is achieved through the following technical solutions：
For manufacturing the epidermal structure of empty iron car body, including filling layer, the both sides of the filling layer are respectively provided with unidirectional carbon fiber
Layer is tieed up, one side of the unidirectional carbon layer away from filling layer sets coverboard, and the coverboard is by PA, PU, basalt fibre
One or more materials are made.
For the hollow iron epidermis quality of the prior art it is larger the problem of, the utility model proposes one kind for manufacturing empty iron vehicle
The epidermal structure of body, this structure include the filling layer positioned at middle part, and the filling layer is used to improve the integral strength of epidermis, uses
Existing high-strength material, such as carbon gold, basalt fibre, carbon fiber.Filling layer is located at two layers of unidirectional carbon fiber layer
Between, unidirectional carbon refers to there is substantial amounts of carbon fiber wire in one direction, only on a small quantity and is typically in other direction
Thin carbon fiber wire, therefore unidirectional carbon layer whole intensity is all in the same direction, is arranged on using unidirectional carbon material

Steel remains the inherent strength of carbon material, and with corrosion-resistant, high-modulus characteristic.Carbon fiber and traditional glass fibers
Dimension is compared, and Young's modulus is it more than 3 times；It is compared with Kafra fiber, and Young's modulus is its 2 times or so, therefore its stretch-proof
It is all highly preferred with shock resistance, as filling layer in use, can significantly ensure sky iron epidermis inner hub location
Structural strength.
Preferably, the filling layer is chopped carbon fiber.Chopped carbon fiber is compared compared to conventional carbon fiber, tension
Stretching intensity can be more obviously improved, and be more applicable for being used as the filling layer of empty iron epidermis so that than passing
The empty iron shell that the metal material of system is made has the strength character being obviously improved.
Preferably, the fibre length of the chopped carbon fiber is between 10~30mm.Ensure at the length of chopped carbon fiber
In in short-range, so that it is guaranteed that enough tensile strengths.
Preferably, the fibre length of the chopped carbon fiber is between 15~25mm.Fiber length ranges are in 15~25mm
Chopped carbon fiber, in addition to excellent tensile strength, additionally it is possible to which, so that the difference in length between each fiber is small, fiber is whole
Body stable structure, shock resistance can be obviously improved.
Preferably, the average value of the fibre length of the chopped carbon fiber is 20mm.Ensure that the fiber of chopped carbon fiber is long
Degree is in stability range.
Preferably, the unidirectional carbon layer is made of N layers of unidirectional lamination, wherein N >=2.It is unidirectional carbon
Layer cloth structure composition made of unidirectional carbon, tensile resistance is high, while can significantly improve the toughness of epidermis.
Preferably, the intensity direction of adjacent two layers unidirectional lamination is mutually perpendicular to.There are one unidirectional lamination all has
Intensity direction, therefore be arranged to be mutually perpendicular to by the intensity direction of adjacent two layers unidirectional lamination in this programme so that it is unidirectional
Carbon fiber layer all has excellent intensity and tensile capacity in orthogonal both direction, so that iron epidermis entirety of having leisure
Can be subjected to the tensile load effect of different directions will not deform, and further improve the structural strength of the utility model.
Orthogonal multilayer unidirectional lamination simultaneously, when being subject to external impacts, impact force action turns on unidirectional lamination
The drawing force to shock point to the unidirectional lamination around shock point is changed to, so as to greatly improve the utility model
Impact resistance.
Preferably, wherein N takes even number.It is the unidirectional lamination that unidirectional carbon layer includes even level so that single
To carbon fiber layer in orthogonal both direction, tension is consistent with bearing capacity, no matter is made using which direction
For the longitudinal direction of empty iron, the overall construction intensity of the utility model is not all interfered with.
Preferably, the unidirectional carbon layer is made of the strip unidirectional lamination mutually wound.It is by strip
Unidirectional lamination winding forms unidirectional carbon layer, is mutually wound between unidirectional lamination so that mutual entirety
Property is greatly improved, and can share stress, the stretching and shearing of bearing bigger mutually, therefore can significantly improve intensive properties
