Structure, by buckling the cooperation with card base, so that mainboard spring is wrapped in buckle by buckle.
Be further improved: the subplate spring is laid with vertically using several layers composite material, between adjacent two layers composite material
The angle of fiber is mutually perpendicular to.
Be further improved: the mainboard spring is tiled using several layers composite material, wherein at least there is one layer of composite wood
Fiber in material is 90 degree, and the fiber in remainder layer in composite material is 0 degree.
Be further improved: the composite material uses epoxy thermoplastics type composite material.
A kind of process making mainboard spring Yu subplate spring, including following steps；
A, release agent is uniformly smeared in mold, and then mold is put into moulding press afterwards；
B, then the temperature setting of moulding press is started to warm up at 100 degree, etc. after temperature are raised to 100 degree, keep the temperature 20 points
Clock guarantees that mould inside temperature is uniform；
C, moulding press continues to suppress for three seconds with 3mpa pressure, and 6 times repeatedly；

Advantages of the present invention: then the structure design of double arch bar springs of mainboard spring and subplate spring passes through mainboard spring and subplate
The difference of the direct paving mode of spring, including mainboard spring level are laid with, and fiber is laid in primary and secondary leaf spring with 0 degree of level and is laid with vertically,
And fleece-laying is with 0/90 positive quadraturing laying；So that the rigidity of entire leaf spring generates variation, possess not in the different carrying stages
Same rigidity, the height of compressional zone can be changed with requirement difference.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Fig. 2 is the structural schematic diagram that the present invention buckles.
Specific embodiment
The present invention is described below with reference to the accompanying drawings of the specification.
It is as shown in the figure: a kind of double arches overlapping variation rigidity leaf spring being staggered using the perpendicular paving of horizontal paving, including mainboard spring 1
With subplate spring 2, the mainboard spring 1 and subplate spring 2 are domes, and the region between the mainboard spring 1 and subplate spring 2 is
Compressional zone 3 is equipped with buckle 4 at the both ends of the subplate spring 2, and the section of the buckle 4 is " U "-shaped, the two of the buckle 4
End is equipped with the card base 5 stretched out to 4 inside of buckle, and the subplate spring 2 and buckle 4 and card base 5 are structure as a whole, by buckle 4 with
The cooperation of card base 5, so that mainboard spring 1 is wrapped in buckle 4 by buckle 4.
The subplate spring 2 is laid with vertically using several layers composite material, the angle of fiber between adjacent two layers composite material
It is mutually perpendicular to.
The mainboard spring 2 is tiled using several layers composite material, wherein at least there is the fiber in one layer of composite material
It is 90 degree, the fiber in remainder layer in composite material is 0 degree.
The composite material uses epoxy thermoplastics type composite material.
A kind of process making mainboard spring Yu subplate spring, including following steps；
A, release agent is uniformly smeared in mold, and then mold is put into moulding press afterwards；
B, then the temperature setting of moulding press is started to warm up at 100 degree, etc. after temperature are raised to 100 degree, keep the temperature 20 points
Clock guarantees that mould inside temperature is uniform；
C, moulding press continues to suppress for three seconds with 3mpa pressure, and 6 times repeatedly；
D, then at 120 degree, keeps the temperature 10 minutes at 120 degree of arrival；
E, moulding press is suppressed with 4mpa pressure, and keeps continuous, temperature power supply is cut off, so that temperature drops automatically
To room temperature；
F, mold separation is finally taken out into test specimen.
Its working principle is that: firstly, the use several layers composite material of mainboard spring 2 tiles, wherein at least there is one layer to answer
Fiber in condensation material is 90 degree, and the fiber in remainder layer in composite material is 0 degree, and the fiber of mainboard spring is with 0 degree of horizontal laying
Supplemented by 90 degree main；So that the rigidity of entire leaf spring generates variation, such design can guarantee leaf spring fiber when meeting production
Intensity is bigger under the premise of silk will not misplace, and improves processing quality and precision.
The subplate spring 2 is laid with vertically using several layers composite material, the angle of fiber between adjacent two layers composite material
It is mutually perpendicular to, vertical laying ensure that 2 stress of subplate spring is dispersed in vertical each face.Since subplate spring 2 does not need too greatly
Intensity, under certain fabrication process condition, 0 degree of laying can make production simpler, and under certain material, vertical laying
Intensity can and horizontal laying have greatly changed.
By the cooperation of mainboard spring 1 and subplate spring 2, it ensure that the bending strength of subplate spring 2 is less than mainboard at the beginning of design
Spring 1, at the beginning of load, since stress is relatively small, the deflection of subplate spring 2 is greater than mainboard spring 1, load increase gradually with
Afterwards, the modified difference of subplate spring 2 and mainboard spring 1 is equal to difference in height when not loading between mainboard spring 1 and subplate spring 2, at this time mainboard
Spring 1 and subplate spring 2 are in contact, and for subplate spring 2 with mainboard spring 1 by synchronous deformation, the main object that carries is main leaf spring 1.
The above description is only an embodiment of the present invention, is not intended to limit the scope of the invention, all to utilize this hair
Equivalent structure or equivalent flow shift made by bright specification and accompanying drawing content is applied directly or indirectly in other relevant skills
Art field, is similarly included within the scope of the present invention.
