Description
Technical field
Vehicle sheet steel spring art is the utility model is related to, more particularly to a kind of prevents automobile leaf spring from wrong piece occurs
Structure.
Background technology
On relative rotation backup plate spring between the main spring reed of usual variation rigidity leaf spring plus clip is spacing, between main spring and auxiliary spring
Relative rotation by U-bolt install it is spacing.But needed for convenience of assembling, U-bolt opens the maximum that shelves are greater than plate spring assembly
Width, therefore certain interval between bolt and reed be present, depends that U-bolt is spacing alone, and the wrong sector-meeting between major-minor spring is than more serious.In
A kind of new steel plate spring mistake proofing plate rack structure is disclosed in state patent CN203515961U, it is proposed that using U-type groove plate come
The method for preventing leaf spring mistake piece.This method needs to increase by a pressed sheet, adds the weight of leaf spring, while the thickness that leaf spring is overall
Also can increased.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of leaf spring Anti-error structure, and the Anti-error structure is normal
Advise and be provided with a locating surface on the stud of centre bolt, the axial rotation free degree of reed, spacing hole are limited using the locating surface
Can directly punching press obtain, centre bolt can be also integrally formed, and processing is simple and convenient, and does not increase the weight of leaf spring, mistake proofing effect
Fruit is reliable, has saved the human cost of material and installation.
What the utility model was realized in：A kind of leaf spring Anti-error structure, including some reeds being stacked and
The pad being arranged between neighboring leaves, some described reeds are fixedly linked by centre bolt, and the center of the reed opens up
Limited location hole, the limited post being engaged with spacing hole, the limited post and spacing hole phase are provided with the middle part of the centre bolt
The free degree for coordinating limitation reed to be rotated about axis.
The spacing hole is square hole, slotted hole, elliptical aperture, polygonal hole or irregularly-shaped hole.
The centre bolt is integrally molded so as an entirety with limited post.
Described limited post body is cube, and limited post both sides are the arc section to smoothly transit, now the spacing hole
For the slotted hole being engaged with limited post.
The screw head external diameter of the centre bolt is more than the width of spacing hole.
The length for some reeds being stacked is gradually reduced from top to bottom.
Some reeds being stacked form plate spring assembly, and the plate spring assembly front end is connected by preceding grasswort by fixing bolt
It is connected on vehicle frame, is connected in the middle part of plate spring assembly by U-bolt with vehicle bridge, plate spring assembly rear end is connected to vehicle frame by hanger.
The utility model leaf spring Anti-error structure is provided with a locating surface on the stud of Traditional center bolt, utilizes this
Locating surface limit reed the axial rotation free degree, spacing hole can directly punching press obtain, centre bolt can be also integrally formed, and be added
Work is simple and convenient, and does not increase the weight of leaf spring, and mistake proofing effect is reliable, has saved the human cost of material and installation.

Embodiment
With reference to specific embodiment, the utility model is expanded on further.It should be understood that these embodiments are merely to illustrate this
Utility model rather than limitation the scope of the utility model.In addition, it is to be understood that reading the content of the utility model statement
Afterwards, those skilled in the art can make various changes or modifications to the utility model, and these equivalent form of values equally fall within this Shen
Please appended claims limited range.
Embodiment 1
As shown in figure 1, a kind of leaf spring Anti-error structure, including some reeds 1 being stacked and it is arranged on adjacent spring
Pad 2 between piece, some described reeds 1 are fixedly linked by centre bolt 3, and the center of the reed 1 offers spacing hole
11, the middle part of the centre bolt 3 is provided with the limited post 31 being engaged with spacing hole 11, the limited post 31 and spacing hole 11
It is engaged the free degree that limitation reed 1 is rotated about axis；
, it is necessary to ensure that limited post 31 can not rotate in spacing hole 11 in the utility model, therefore, the spacing hole 11
For square hole, slotted hole, elliptical aperture, polygonal hole or irregularly-shaped hole.
In order to easy to process, cost is reduced, opinion avoids the faying face of centre bolt 3 from producing shear stress affact intensity, institute
State centre bolt 3 and be integrally molded so as an entirety with limited post 31.
As shown in Fig. 2 in the present embodiment, cut to reduce the generation of the forced position of the limited post 31 and spacing hole 11
Stress tears reed, preferably, the described body of limited post 31 is cube, the both sides of limited post 31 are the circular arc to smoothly transit
Section 32, now the spacing hole 11 is the slotted hole being engaged with limited post 31.
In the utility model, in order to ensure that some reeds 1 that layer stackup is set can be reliably fixedly connected, in described
The external diameter of the screw head 33 of heart bolt 3 is more than the width of spacing hole 11；In addition, it is generally the case that some springs being stacked
The length of piece 11 is gradually reduced from top to bottom.
As shown in figure 3, some reeds 1 being stacked form plate spring assembly, the plate spring assembly front end passes through preceding grasswort 4
It is connected to by fixing bolt on vehicle frame, limits leaf spring X, Y and Z-direction motion；Connected in the middle part of plate spring assembly by U-bolt 6 and vehicle bridge 5
Connect, accept the various load that ground is transmitted to tire；Plate spring assembly rear end is connected to vehicle frame by hanger 7, is swung by hanger, protects
Demonstrate,prove the elastic deformation of leaf spring.
