Abstract
The utility model discloses a kind of steady return cluster spring, including in a ring and axis overlaps the top piece set and lower top flat, and the multiple sub-springs being connected between two top flats, circumference of the multiple sub-spring along the top flat are equidistantly arranged；The multiple sub-spring includes multiple first sub-springs and the second sub-spring, and the rotation direction of the first sub-spring is oppositely oriented with the second sub-spring, and the quantity of the first sub-spring is equal to the quantity of the second sub-spring.Because the cluster spring employs two kinds of different sub-springs of rotation direction, thus the face loaded stabilization of cluster spring is not offset, and spring stress is stable, long lifespan.
Description
Technical field
It the utility model is related to a kind of cluster spring, more particularly to a kind of steady return cluster spring.
Background technology
Spring is widely used in energy storage reset components in people's daily life and industry manufacture field, its importance do not say and
Analogy.In automobile manufacture industry, dynamical system needs to use a variety of different sizes and the spring acted on to meet the fortune of wherein mechanism
Make.But existing spring is under certain loads, reversing certainly for spring coil often occurs, end face where causing upper and lower free end
Center is misaligned, spring face skew loaded, finally make it that spring stress is unstable.For a long time by after alternate load so that spring
Constantly by the shear stress of alternation, spring breakage is caused.How the face loaded of stabilizing spring, be this case need solve ask
Topic.
Utility model content
The purpose of this utility model is to provide a kind of steady return cluster spring, steady suitable for being provided in set space
The fixed face loaded not offset, spring stress is stable, long lifespan.
To achieve the above object, the technical solution of the utility model is as follows：
A kind of steady return cluster spring, including in a ring and axis overlaps the top piece set and lower top flat, Yi Jilian
The multiple sub-springs being connected between two top flats, circumference of the multiple sub-spring along the top flat are equidistantly arranged；
The multiple sub-spring includes multiple first sub-springs and multiple second sub-springs, the rotation direction of the first sub-spring and the
Two sub-springs it is oppositely oriented, and the quantity of the first sub-spring is equal to the quantity of the second sub-spring.
In one embodiment：First sub-spring and the second sub-spring are separated by arrangement.
In one embodiment：At least two first sub-springs form the first sub-spring group, and at least two second sub-springs are formed
Second sub-spring group, the first sub-spring group are separated by arrangement with the second sub-spring group.
In one embodiment：The upper and lower top flat, provided with mounting post, has back towards the side of sub-spring outside mounting post
Turn face, sub-spring is set in outside corresponding mounting post in an interference fit.
In one embodiment：The upper and lower top flat is additionally provided with through hole in the position of corresponding mounting post, and the through hole penetrates institute
Mounting post is stated, and the internal diameter of the through hole is less than the internal diameter of sub-spring.
After adopting the above technical scheme, it is oppositely oriented due to first, second sub-spring, and quantity is identical, cluster spring
Overall moment of torsion is cancelled out each other, thus the trend mutually reversed between upper and lower top flat there will be no, improve cluster spring by
Power stability.
Brief description of the drawings
Fig. 1 is the schematic perspective view of cluster spring；
Fig. 2 is the top view of cluster spring；
Fig. 3 is the partial sectional view of Section A-A in Fig. 2；
Fig. 4 is a kind of arrangement schematic diagram of sub-spring group；
Fig. 5 is another arrangement schematic diagram of sub-spring group.
Embodiment
Fig. 1-3, a kind of steady return cluster spring 1, including top piece 11 in a ring and lower top flat 12 are refer to, should
The axis of upper and lower top flat, which overlaps, to be set.The cluster spring 1 also includes the multiple sub-springs being connected between two top flats, described more
Circumference of the individual sub-spring along the top flat is equidistantly arranged.By being exerted a force to upper and lower top flat, the sub-spring, which can be compressed, makes its hair
Raw deformation energy storage.
The upper and lower top flat is convexly equipped with the mounting post 13 with the surface of revolution towards the side of sub-spring.Outside the mounting post
Footpath is slightly larger than the internal diameter of corresponding sub-spring, and sub-spring is installed in an interference fit to be set in outside corresponding mounting post 13, with
Complete the connection of three.
The upper and lower top flat is additionally provided with through hole 14 in the position of corresponding mounting post, and through hole penetrates the mounting post,
So that mounting post is configured to hollow ringwall structure.The internal diameter of the through hole 14 is respectively less than the internal diameter of sub-spring so that sub-spring
By the region that support is fixed, its inside has hollow structure.So design after, can under conditions of top flat intensity is not reduced,
The consumptive material of top flat is set to decrease.
The multiple sub-spring, including multiple first sub-springs 11 and multiple second sub-springs 12, and the first sub-spring
Rotation direction is oppositely oriented with the second sub-spring, and the quantity of the first sub-spring is equal to the quantity of the second sub-spring.Cluster spring
After compression, wire coil around and remaining distorting stress generates the moment of torsion of corresponding rotation direction and passes to the upper and lower top flat so that
The trend mutually reversed be present in upper and lower top flat；And it is oppositely oriented due to first, second sub-spring, and quantity is identical, combines bullet
The overall moment of torsion of spring is cancelled out each other, thus the trend mutually reversed between upper and lower top flat there will be no, and improve cluster spring
Force stability.
In the present embodiment, the sub-spring 12 of the first sub-spring 11 and second is separated by arrangement, to be uniformly distributed sub-spring pair
The twisting resistance that top flat applies, reduce the situation that the issuable shear stress of both intersections is concentrated.Certainly, in other embodiment
In, reference picture 4-5, at least two first sub-springs 11 form the first sub-spring group 15, and at least two second sub-springs 12 are formed
Second sub-spring group 16, the first sub-spring group are separated by arrangement with the second sub-spring group.
Preferred embodiment of the present utility model is the foregoing is only, not thereby limits its scope of the claims, it is every to utilize this
The equivalent structure transformation that utility model specification and accompanying drawing content are made, directly or indirectly it is used in other related technology necks
Domain, similarly it is included in scope of patent protection of the present utility model.
