Description
Technical field
The utility model belongs to commercial car field, and in particular to a kind of square SCR cassette carriers of heavy truck, especially one
SCR casees (urea box) bracket of heavy type traction automobile is planted, the matching Weihe River bavin that is particularly suitable for use in carries the heavy type traction of square SCR casees
Automobile.
Background technology
At present, in heavy truck industry, SCR cassette carriers are mostly L-type right-angle structure form, and square SCR cassette carriers are total
Into being fixed on vehicle frame.Bracket assembly is made up of cambered plate, L-type right-angled bracket and welded nut, and welded nut is welded on arch
On plate, cambered plate and L-type right-angled bracket weld together.Such a right-angled bracket structure is although simple in construction, and easy to manufacture, but
The square SCR casees section for being matching is arc, if the SCR cassette carriers of this right-angle structure are matched, in bracket corner and SCR casees
Certain gap is had, SCR casees are fitted not exclusively with bracket, cause the contact area of SCR casees and bracket small, frictional force is inadequate,
Play before and after SCR can be caused, and because larger in L bracket corner stress, so causing bracket to be broken, so as to influence whole
The reliability of gas extraction system.And because being fixed at vehicle frame variable cross-section, former and later two cambered plate structures are different, can so lead
Cause carrier structure species more, be unfavorable for modularized design.
Utility model content
The purpose of this utility model is to provide a kind of square SCR cassette carriers of heavy truck, increases square SCR casees and bracket
Between contact area, increasing friction force, reduction SCR casees before and after play possibility, and change bracket cross-section structure, reduce
The stress of corner, improves the reliability of gas extraction system, and select this SCR cassette carriers structure, it is possible to achieve the mould of bracket
Block, reduces bracket species.
The technical solution of the utility model is：A kind of square SCR cassette carriers of heavy truck, it is characterised in that：Including bow
Shape plate 2, arc-shaped bracket 9, clamping band assembly 6 and locking nut 8；Cambered plate 2 is fixedly connected with the upper end of arc-shaped bracket 9, clamping band 3
Top is fixed on cambered plate 2, and bottom is fixed on the lower end of arc-shaped bracket 9 by locking nut 8；Arc-shaped bracket 9 by with it is square
Two arcuate structure compositions of SCR casees section identical, the point of intersection of two arcuate structures passes through arc-shaped transition.
Beneficial effect：The utility model adds the contact area of square SCR casees and bracket assembly, increases square SCR casees
With the frictional force of bracket, reduce the stress of bracket corner, improve the reliability of gas extraction system；Square SCR brackets can be realized
Modularization, reduce the total class of bracket；It is lightweight compared with L-type right-angled bracket.

Embodiment
To make the purpose of this utility model, content and advantage clearer, embodiment of the present utility model is made
It is described in further detail.
The utility model provides a kind of square SCR cassette carriers of heavy truck, including cambered plate 2, arc with pad
Bracket 9, Hex welding nut 10, clamping band assembly 6, locking nut 8, cambered plate 1 are welded by welded nut with arc-shaped bracket 9
Connect.
The vertical direction of cambered plate 2 has four a diameter of φ 15 hole, pitch of holes be respectively from the top down 50mm, 90mm,
50mm, is used to increase cambered plate intensity, in one thickness of topmost hole position spot welding for 3mm pad during welding packing ring for left and right partially
Heart spot welding, reduces the stressing conditions of cambered plate, improves the overall structural strength of bracket, prevents bracket arch under severe road conditions
Plate top is torn.The hole position of bottom 3 welds 3 Hex welding nuts, can so improve technique during entrucking.Arch thickness of slab
Spend for 4-6mm, from the aspect of drop weight, preferably 4mm, material is 510L steel.
The use of arc-shaped bracket 9 and square SCR casees section identical arcuate structure, sidepiece radius are R1884mm and bottom half
Footpath is the arcuate structure of two kinds of arcs of R1982mm, the arc-shaped transition that the point of intersection of two arcs is R92mm with radius, and this can be with
The contact area of the square SCR casees of Proper Match and bracket, the contact area of increase bracket and square SCR casees increases SCR casees and support
The frictional force of frame, is conducive to improving SCR reliability.
As seen from Figure 4, arc-shaped bracket section is " several " character form structure, and such structure can reduce corner with bracket
Stress；Three a diameter of φ 25mm holes are arranged at arc-shaped bracket bottom, and pitch of holes is 100mm (as shown in Figure 3), and increase hole is on the one hand
Bracket weight can be reduced, on the other hand can prevent rainwater from entering in arc-shaped bracket, corrosion bracket, influence bracket uses the longevity
Life.Arc-shaped bracket thickness is 4-6mm, from the aspect of drop is heavy, preferably 4mm, and material is 510L steel.Arc-shaped bracket 9 is welded with cambered plate 2
It is connected together.
By increasing the backing plate of different-thickness behind cambered plate, it is possible to achieve from different in width, the car of different variable cross-sections
Frame is fixedly connected, and realizes the modularization of SCR cassette carrier assemblies, reduces square SCR cassette carriers species.
By the way that L bracket is changed to, sidepiece radius is R1884mm to the utility model and bottom radius is two kinds of R1982mm
The arcuate structure of arc, the arc-shaped transition that the point of intersection of two arcs is R92mm with radius, so can both increase bracket with
The contact area of SCR casees, increases the frictional force of SCR casees and bracket, and arc-shaped bracket structural profile is " several " character form structure, such
Structure can reduce the stress of corner.
Three holes are arranged at arc-shaped bracket bottom, and on the one hand increase hole can reduce bracket weight, on the other hand can prevent rain
Water enters in arc-shaped bracket, corrosion bracket, influences bracket service life.
