Description
Technical field
This utility model relates to the panel spring hold-down plate of a kind of truck balance suspension, belongs to truck suspension systems technology field.
Background technology
Truck back balance suspension uses the structure of oblique pull U-bolt at present, and panel spring hold-down plate has because of the difference of leaf spring thickness
A variety of, structure is similar to, but needs to be designed, and uses different moulds to produce, final machine-shaping, when assembling in workshop,
The phenomenon of misloading may be caused because structure is similar, cause U-bolt to coordinate with pressing plate bad, ultimately result in U-bolt
Loosen.The way of the corresponding a kind of panel spring hold-down plate of a kind of leaf spring thickness, causes parts kind many, is unfavorable for part management, and zero
Parts assemble.
Utility model content
This utility model patent, for above-mentioned deficiency, devises one and assembles oblique pull U-bolt and many leaf springs from top to bottom
General panel spring hold-down plate.
The technical solution of the utility model:
A kind of assembling oblique pull U-bolt and the panel spring hold-down plate of many plate spring universals from top to bottom, uses symmetrical structure, including on
Plane, lower plane, central part；Upper planar shaped becomes two cambered surfaces of the depression symmetrical with central part, and cambered surface surface is joined with U-bolt
Closing, this arc length and locus meet: include quadrilateral area, and this quadrilateral area is more than or equal to from different-thickness leaf spring
The scope of stress area of union that formed of corresponding size；The angle of inclination of two cambered surfaces is mated with oblique pull U-bolt；In pressing plate
The heart is provided with the circular hole dodging plate spring center bolt and nut.
Further, symmetrical, symmetrical before and after two cambered surfaces.
Further, upper plane two ends are spacing wall construction.
Further, around the hole of central part, upper end is provided with symmetrical grooves, and lower end is provided with recess.
Further, lower plane two ends tilt, and lower plane is not parallel with horizontal plane.
Therefore, in the design process of panel spring hold-down plate, the planning of leaf spring, the thickness of foundation leaf spring and U-bolt and pressure are understood
The rigging position of plate, determines the shape in the hole of pressing plate, and the leaf spring of (such as lacking leaf spring) different-thickness of such same type is with same
One panel spring hold-down plate, decreases the kind of panel spring hold-down plate, adds versatility and the concordance of parts, decreases design work
Amount, reduces processing cost, simplifies the assembling complexity brought owing to product category is various.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of panel spring hold-down plate of the present utility model；
Fig. 2 is the assembling schematic diagram of an embodiment of panel spring hold-down plate of the present utility model；
Fig. 3 is the schematic diagram of an embodiment of panel spring hold-down plate of the present utility model；
Detailed description of the invention
With embodiment, this utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Fig. 1 schematic diagram, the big triangle of solid line and the big triangle of dotted line represent and thin plate spring and with the thickest respectively
The panel spring hold-down plate that leaf spring coordinates, the two contour dimension is identical, plane and U-bolt profile on plane, panel spring hold-down plate on leaf spring
As it can be seen, the upper plane of pressing plate is perpendicular to the centrage of U-bolt.
When pressing plate is with when slab spring coordinates, and the region that U-bolt shares with pressing plate is AB'C'D, it is determined that pressing plate cambered surface
The minor face AD coordinated with U-bolt；When pressing plate is with when thin plate spring coordinates, and the region that U-bolt shares with pressing plate is A'
BCD', it is determined that the longest edge BC that pressing plate cambered surface coordinates with U-bolt；Therefore, the pressing plate cambered surface coordinated with many thickness leaf spring and U
The region that type bolt coordinates is ABCD.
As in figure 2 it is shown, leaf spring 4 is contained on balance shaft housing 5, U-bolt 2 assembles from top to bottom, clamping axle housing 5 and leaf spring 4,
After panel spring hold-down plate 1, assemble and urgent with nut, it is ensured that enough screw-down torques, produce enough pretightning forces, it is ensured that spiral shell
Bolt 2 will not loosen.
As it is shown on figure 3, the length of the cambered surface 6 of panel spring hold-down plate is suitable for the connection of multiple thickness leaf spring, the gradient of cambered surface 6 can
To mate with the oblique pull U-bolt 2 assembled from top to bottom, symmetrical, symmetrical before and after pressing plate two cambered surface 6, interstitial hole 7 can be dodged
The centre bolt 3 of leaf spring.
In conjunction with Fig. 2 and Fig. 3, it can be seen that the cambered surface 6 on panel spring hold-down plate has reserved the space of abundance so that different thick in assembling
During the leaf spring 4 spent, use same panel spring hold-down plate 1 just can complete assembling.
So the same panel spring hold-down plate of leaf spring of (such as lacking leaf spring) different-thickness of same type, decreases leaf spring pressure
The kind of plate, adds versatility and the concordance of parts, decreases design efforts would, reduce processing cost, simplify
The assembling complexity brought owing to product category is various.
Finally should be noted that: above example is only in order to illustrate that the technical scheme of this case is not intended to limit；Although
Being described in detail this case with reference to preferred embodiment, those of ordinary skill in the field are it is understood that the most permissible
The detailed description of the invention of this case is modified or portion of techniques feature is carried out equivalent；Without deviating from the technical program
Spirit, it all should be contained in the middle of the technical scheme scope that this case is claimed.
