Abstract
The invention discloses a new multi-leaves whole cup spring, comprising multi-leaves folded flat bar with different length. Among adjacent flat bar the parts near two ends of the flat bar with shorter length are fixed together with flat bar with longer length at least so that there is no relative displacement appeared. By the new multi-leaves whole cup spring bearing ability is improved in whole and the working principle of prior cup spring is changed ultimately. In the same material usage bearing ability and rigidity are largely improved. The cost of cup spring is decreased and it is especially applied in large-scaled truck, building structure or bridge structure.
Description
Technical field
The present invention relates to a kind of leaf spring, be a kind of can whole simultaneously stressed leaf spring.
Background technique
Leaf spring by the different arc plate of multi-disc length for example the plate 1,2,3,4 among Fig. 1 overlap and tighten together from the middle part and constitute with fastening piece 10, be used for vehicle vibration damping more, have the characteristics of good springiness.At present, leaf spring is used for construction engineering or bridge works, has also obtained effect preferably.
Because leaf spring is at present most widely used to be at automotive field, be the design standard of leaf springs of car so the design standard of leaf spring still adopts at present, adopt the Japanese standard practice.Because the general maximum of carload has only tens tons of weights, the general used alloy material of leaf springs of car is 60Si2Mn, and building or bridge structure weight can reach the hundreds of thousands ton to millions of ton, so the leaf spring that uses on the general automobiles can not satisfy building or the bridge spring needs to rigidity.For rigidity that leaf spring is provided to adapt to the requirement of building or bridge, building or bridge structure will adopt high-grade alloy material for this reason, material such as 35CrTi and 38SiMnVB for example, but also only make the rigidity maximum of material be increased to 1.3 times, and material price is also much higher than the alloy material that common leaf spring is used.Therefore, be used to build or the leaf spring of bridge structure also will improve the bearing capacity and the rigidity of leaf spring by the quantity that increases plate.
Because the plate of leaf spring overlaps, the radius of curvature of plate can change when stressed, and its each adjacent sheet is in length direction generation relative displacement at this moment, and promptly having slides produces.Particularly for corrosion-resistant needs also will boil black the processing to plate, so its frictional force of existence owing to paint film is littler between the plate.Therefore, the plate of all at present leaf springs all is that each sheet works independently.That is to say that the N that the present whole maximum load-carrying capacity of leaf spring that is made of N sheet plate is the monolithic plate doubly.Because the building or the weight of bridge are much larger than the weight of automobile, thus this to cause the No. of plates of required leaf spring on the one hand also be very big, this makes cost be multiplied, and can't carry out metal heat treatmet when integral thickness is blocked up on the other hand, or it is not saturating to quench.
Summary of the invention
At the problems referred to above that present leaf spring is used to build or bridge structure exists, the object of the present invention is to provide a kind of novel multiple leaf spring, but this multiple leaf spring overall work, thereby its bearing capacity can become quadratic relationship to increase, and reduced the cost of leaf spring.
The present invention adopts following technical solution, a kind of novel multiple-sheet integral plate spring, comprise the different plate of length that multi-disc overlaps, the short plate of length mutually combines by fastening structure than long plate with length in its part near two ends at least in the adjacent plate, makes it that relative displacement can not take place.
The present invention mutually combines between the adjacent plate owing to logical fastening structure makes, when the leaf spring that is made of the multi-disc plate is stressed, relative displacement can not take place in adjacent plate, make that leaf spring can overall work, its integral rigidity and bearing capacity have been improved greatly, therefore can reduce No. of plates reduces its cost, is particularly suitable for building or bridge and large-scale truck and uses.

Fig. 2 is a novel multiple-sheet integral plate spring structural representation of the present invention.
Fig. 3 is the partial enlarged drawing of the I of Fig. 2.
Fig. 4 is the another kind of structural representation of novel multiple-sheet integral plate spring of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments novel multiple-sheet integral plate spring of the present invention is described further.
As shown in Figures 2 and 3, be a kind of novel multiple-sheet integral plate spring structural representation of the present invention, overlap by different 4 plates 1,2,3,4 of length and form, and medium position is tightened together with fastening pieces such as clamp 10.In adjacent plate, length is passed through concaveconvex structure 21,32,43 tablings with length than long plate in its part near two ends than short plate, when on leaf spring, applying active force like this, because adjacent plate is the effect of the shearing resistance of chimeric concaveconvex structure mutually, stoped between the adjacent plate and slided, made lap be equivalent to an one-piece element.Protruding structure in the concaveconvex structure is the salient point on the plate, and recessed structure then is the groove of corresponding position on the corresponding plate, and its quantity and sectional area and the distribution on plate are calculated according to the shearing force of the size generation of suffered load.
Certainly, adjacent plate can also adopt fastening structures such as pin 5 or bolt to make mutual fastening combination in the position near its end with mode shown in Figure 4, or is snapped together with clamp, to prevent slide relative.But because through hole is set, can make plate bigger than adopting concaveconvex structure when adopting pin or bolt in the intensity reduction amplitude of this position.
Module of anti-bending section formula W=bh according to the rectangular cross-section material
2/ 6 as can be known, and wherein h is the thickness of plate, and when plate that to adopt n thickness be h was superimposed, then because employing Fig. 2 or structure shown in Figure 4, n plate was stressed member as a whole, and the module of anti-bending section of its whole leaf spring then is W=b (nh)
2/ 6=n
2(bh
2/ 6), be the n of monolithic plate module of anti-bending section
2Doubly.
When adopting the common plate spring structure that slide displacement can take place shown in Figure 1, because the plate of leaf spring is burst work, so the module of anti-bending section of the leaf spring that n sheet plate constitutes is the superposition value of each sheet, i.e. W '=n (bh
2/ 6), the n that is the monolithic plate doubly.
Because n is a natural number, so for the identical spring of No. of plates, adopt technological scheme of the present invention, the bearing capacity of the leaf spring integral body that it is made up of the multi-disc plate is greater than the bearing capacity of the leaf spring of ordinary construction, therefore under same load-up condition, can effectively reduce the quantity of plate, perhaps adopt the lower plate material sheet of price, therefore can reduce the cost of leaf spring.
