Specific embodiment
It elaborates below with reference to Fig. 2 to Fig. 7 to the embodiment of the present invention.
Laminated spring, the partition 2 including rubber bodies 1 and vulcanization in rubber bodies 1, the partition 2 of multilayer are evenly spaced on,
And the outer end of each layer partition 2 is vertically aligned, the width of the adjacent partition 2 is unequal to make 2 inner end of adjacent separator in rubber
It is in staggered distribution in body 1, and forms flare form between the outer end of adjacent separator 2, rubber bodies 1 are located between 2 outer end of adjacent separator
Rubber-type face 11 be " people " font type face from inside to outside, rubber-type face 11 is with the compression of rubber bodies 1 and from inside to outside gradually
Fitting.
As shown in Figures 2 and 3, the width of the adjacent separator 2 in laminated spring is unequal, due to the stress collection of partition 2
In partition inner end, adjacent separator 2 is of different size at midpoint, so that the inner end of adjacent separator 2 is not aligned in same vertical plane, i.e., it is adjacent
The stress concentration point of partition 2 is in staggered distribution, and when laminated spring, which carries, to be compressed, the longer partition 2 of width is answered in adjacent separator 2
Power centrostigma is distributed in the inside of the stress concentration point of the partition 2 short compared with width, and the stress concentration point with the longer partition 2 of width
The vertical plane of alignment is rubber bodies, is transmitted to stress every on entire partition by partition inner end by the deformation of rubber bodies, can subtract
The stress of few partition inner end is concentrated, and the stress value of partition inner end is smaller, avoids partition inner end stress is excessive from causing to be broken；And it is adjacent
The inner end of the shorter partition 2 of width is in the outside of longer 2 inner end of partition of width in partition 2, and inner end is more lived outside suffered by it and answered
Force value is smaller, thus the shorter partition inner end of width have compared with the stress that avoids concentrate, suffered stress is smaller, can effectively prevent
Partition 2 is broken.Furthermore the rubber-type face 11 between 2 outer end of adjacent separator is designed as " people " font type face from inside to outside, phase
Face is done to " U " font between adjacent separator outer end than in the prior art, the rubber-type face 11 of " people " font can be with rubber bodies 1
It compresses and is gradually bonded, not will form the fold in rubber-type face 11, so that rubber-type face be avoided to generate fatigue crack because of fold.The
Three, flare form is formed between the outer end of adjacent separator 2, increases compressive deformation space of the rubber bodies 1 between adjacent separator, can have
Effect prevents rubber bodies 1 from bloating from the outer end of partition 2, to avoid abrasion of the partition outer end to rubber bodies.
Specifically, a kind of laminated spring as shown in Figure 2, the width from bottom partition 2 to top layer partition 2, which successively increases, to be made
The inner end of bottom partition 2 is successively inwardly put in the inner end of top layer partition 2, and the different widths of adjacent separator 2 are not less than 5 millimeters,
Wherein the stress value of 2 inner end of top layer partition is maximum, transmits stress by the rubber between top layer partition 2 to low layer partition 2, can be substantially

Specifically, as it can be seen in figures 5 and 6, the rubber thickness between the mo(u)ld top half face 11.1 and chamfer bevel face 21 is less than 1
Millimeter, and the outer edge in mo(u)ld top half face 11.1 is overlapped with the outer edge in chamfer bevel face 21, in rubber bodies compression process, mo(u)ld top half face
11.1 rigidity is consistently greater than the rigidity in mo(u)ld bottom half face 11.2, i.e., in compression, type face paste is close gradually downward in mo(u)ld top half face 11.1.
The mo(u)ld bottom half face 11.2 is made of outer inclined-plane 11.21 and the extrados 11.22 being connected to outside outer inclined-plane 11.21,
The outer inclined-plane 11.21 and extrados 11.22 is tangent, and is distributed with mo(u)ld top half face 11.1 in mirror symmetry, and outer inclined-plane 11.21
Width be mo(u)ld bottom half face width 1/5 ~ 1/2.Outer inclined-plane 11.21 and 11.1 mirror symmetry of mo(u)ld top half face make rubber bodies compress early period,
Rubber-type face 11 is bonded, and the inner end in rubber-type face 11 is effectively prevent to generate fold, outer inclined-plane 11.21 and outer arc at modification initial stage
Face 11.22 is tangent, and after outer inclined-plane 11.21 is bonded with mo(u)ld top half face 11.1, mo(u)ld top half face 11.1 is contacted with extrados 11.22, then is led to
Gradually reducing for rubber bodies 1 is crossed, mo(u)ld top half face 11.1 is gradually pressed with outer mold surface 11.22, obtains outer inclined-plane by repetition test
11.21 width be the 1/5 ~ 1/2 of mo(u)ld bottom half face width can have relatively guarantee mo(u)ld top half face 11.1 and mo(u)ld bottom half face 11.2 be bonded and rubber
