The technical scheme is that
A kind of vehicle frame back spring scaffold group, the back spring scaffold being symmetrically installed including two groups, each group of back spring scaffold is by two wing plates
It is formed with a crossbeam, the wing plate is made of edge, wing plate lower edge and bottom plate on wing plate, and edge and wing plate lower edge are trapezoidal on wing plate
Structure, edge is connected with the trapezoidal broadside of wing plate lower edge by bottom plate on wing plate, forms an open end, and the both ends of crossbeam are from opening
End insertion, connect in wing plate；The crossbeam is the hollow pipe of a rectangle, and both ends are equipped with side mounting plate, hollow pipe front and back
Two sides are equipped with multiple through holes, and upper part two sides are equipped with crossbeam cushion block, crossbeam groove are formed between crossbeam cushion block, in crossbeam groove
In be equipped with multiple recess holes；It is designed with corresponding aperture on bottom plate and side mounting plate, and bottom plate and side installation is bolted
Plate, bolt is as side plate bolt herein；Edge and wing plate lower edge are equipped with multiple apertures on wing plate, the edge on crossbeam backing plate and wing plate
Position corresponding with the aperture of wing plate lower edge also is provided with multiple apertures, is bolted, and bolt indulges bolt as wing plate herein；
Position of the two sides of bottom plate on the outside of the mounting plate of side is equipped with multiple apertures, and inside is equipped with wing plate transverse bolt.
Further, the trapezoidal hypotenuse of edge and wing plate lower edge is the short structure in side length one side, long side on the wing plate
For 1.5 times of length of short side.
Further, it is three that the wing plate, which indulges bolt quantity, and arrangement mode is proximate to set on the position of wing plate broadside
It sets two wing plates and indulges bolt, third wing plate indulges the position that bolt is positioned close to trapezoidal hypotenuse long side.
Further, the crossbeam cushion block is connected by welding to crossbeam top, and the thickness of crossbeam cushion block is according on wing plate
The selection setting of the spacing of edge and wing plate lower edge.
Further, the side plate bolt is equipped with 6, is divided into two rows, and 2 intermediate side plate bolts are vertical positioned at wing plate
The centre of bolt location.
Further, the trapezoidal hypotenuse long side of the wing plate of two back spring scaffolds is to be oppositely arranged.
Further, reinforcing rib is equipped between side mounting plate and crossbeam.
The beneficial effects of the present invention are:
1, by setting wing plate to the structure of non-isosceles trapezoid, make its long side close to inner edge, since the supporting section of long side is longer,
It is more dispersed after its stress, biggish gravity can be undertaken, therefore two back spring scaffold long sides are oppositely arranged, its stress can be made to imitate
Fruit is more preferable；
2, wing plate is indulged bolt and is configured according to the distance of long side and short side, and long side can be assisted preferably to realize that stress is equal
The setting of weighing apparatus avoids it from occurring in the problems in some bolt upper stress collection.

Specific embodiment
Present invention will be further explained below with reference to the attached drawings and examples.
As shown in figures 1-4, a kind of vehicle frame back spring scaffold group, the back spring scaffold being symmetrically installed including two groups, after each group
Spring bracket is made of two wing plates 1 and a crossbeam 2, the wing plate 1 by being formed under 11, wing plate along 12 and bottom plate on wing plate,
It along 12 is trapezium structure under 11 and wing plate on wing plate, the trapezoidal broadside on wing plate under 11 and wing plate along 12 passes through bottom plate company
It connects, forms an open end；The crossbeam 2 is the hollow pipe of a rectangle, and both ends are equipped with side mounting plate 25, side mounting plate 25
Reinforcing rib 27 is equipped between crossbeam 2, hollow pipe front and rear sides are equipped with multiple through holes 24, and upper part two sides are equipped with crossbeam cushion block
21, the crossbeam cushion block 21 is connected by welding to 2 top of crossbeam, the thickness of crossbeam cushion block 21 according on wing plate along 11 and wing plate
The lower spacing along 12 selects setting, forms crossbeam groove 22 between crossbeam cushion block 21, multiple grooves are equipped in crossbeam groove 22
Hole 23；It is designed with corresponding aperture on bottom plate and side mounting plate 25, and bottom plate and side mounting plate 25 is bolted, herein spiral shell
Bolt is as side plate bolt 26；Multiple apertures are equipped with along 12 under 11 and wing plate on wing plate, along 11 on 2 backing plate of crossbeam and wing plate
