Description
Technical field
It is specially a kind of hollow with solid secondary car before mixing Aluminum alloy frame casting formula the present invention relates to cast aluminium subframe technical field
Frame.
Background technology
Subframe can regard the skeleton of tandem axle as, be the part of tandem axle.Subframe is not complete
Vehicle frame, tandem axle, the support of suspension are simply supported, vehicle bridge, suspension is connected again with " positive vehicle frame " by it, be traditionally referred to as
" subframe ", existing steel framework formula fore sub frame, finished weight is higher, and single-piece is more, and technique is relatively complicated, material corrosion resistant
Corrosion is poor, therefore, hollow mixing Aluminum alloy frame casting formula fore sub frame with solid we have proposed a kind of.
The content of the invention
It is an object of the invention to provide it is a kind of it is hollow mix Aluminum alloy frame casting formula fore sub frame with solid, to solve the above-mentioned back of the body
The existing steel framework formula fore sub frame proposed in scape technology, finished weight is higher, and single-piece is more, and technique is relatively complicated,
The problem of material corrosion resistance is poor.
To achieve the above object, the present invention provides following technical scheme：It is a kind of it is hollow with it is solid mix Aluminum alloy frame casting formula before
Subframe, including solid restocking and hollow after-frame, the solid restocking are located at the upside of hollow after-frame, the solid restocking and sky
Heart after-frame is integrally formed, and the inner chamber of the solid restocking is evenly arranged with stiffener plate, the top of the solid restocking or so two
Side radially offers location and installation hole, and the upper end at left and right sides of the hollow after-frame antetheca is respectively connected with connecting screw hole group,
Downside at left and right sides of the antetheca of the hollow after-frame is mounted on limiting plate, and it is fixed to be connected with the right side of the hollow after-frame lower end
Position pin, the left and right ends of the hollow after-frame bottom radially offer lower location and installation hole.
Preferably, the U-shaped shape of solid restocking, the both ends of stiffener plate both sides with solid restocking inner chamber respectively
Wall connects.
Preferably, it is connected with reinforcement connecting rod between two groups of support arms on the upside of the hollow after-frame.
Preferably, the rear wall of the hollow after-frame, which uniformly offers, subtracts matter hole.
Compared with prior art, the beneficial effects of the invention are as follows：This is hollow to mix Aluminum alloy frame casting formula fore sub frame with solid,
Different structure is assigned according to different qualities, the advantages of organically combining hollow subframe and solid aluminum alloy subframe, ensures product
Intensity, the complexity of technique is reduced while performance, the weight of product is reduced, reduces oil consumption, improve assembling chi
Very little precision, reduces recovery difficult.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Fig. 2 is Section A-A figure of the present invention；
Fig. 3 is section B-B figure of the present invention.
In figure：1 solid restocking, 2 hollow after-frames, 3 stiffener plates, location and installation hole on 4,5 connecting screw hole groups, 6 limiting plates,
7 alignment pins, 8 times location and installation holes.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
Fig. 1-3 are referred to, the present invention provides a kind of technical scheme：It is a kind of hollow with solid secondary car before mixing Aluminum alloy frame casting formula
Frame, including solid restocking 1 and hollow after-frame 2, solid restocking 1 are located at the upside of hollow after-frame 2, solid restocking 1 and hollow after-frame 2
It is integrally formed, the inner chamber of solid restocking 1 is evenly arranged with stiffener plate 3, is radially opened up at left and right sides of the top of solid restocking 1
There is a upper location and installation hole 4, the upper end at left and right sides of the hollow antetheca of after-frame 2 is respectively connected with connecting screw hole group 5, before hollow after-frame 2
Downside at left and right sides of wall is mounted on limiting plate 6, and alignment pin 7, the hollow bottom of after-frame 2 are connected with the right side of the hollow lower end of after-frame 2
The left and right ends in portion radially offer lower location and installation hole 8.
Wherein, solid 1 U-shaped shape of restocking, the two side of the both ends of stiffener plate 3 respectively with the solid inner chamber of restocking 1 are connected,
Reinforcement connecting rod is connected between two groups of support arms of the hollow upside of after-frame 2, the rear wall of hollow after-frame 2, which uniformly offers, subtracts matter
Hole.
In use, the aluminum alloy materials of this programme have, density is small, formability is good, the characteristics of excellent corrosion resistance, weight
It is relatively low, oil consumption is reduced, is advantageous to promote automobile industry energy-saving and emission-reduction, by solid restocking 1 and the combination of stiffener plate 3, is improved
Structural strength, it is connected between two groups of support arms of the upside of hollow after-frame 2 and strengthens connecting rod and improve structural strength, aluminum alloy auxiliary vehicle frame
Because using monoblock cast, dimensional accuracy is preferable, and the density of aluminium is only the 1/3 of steel, can be had using aluminum-steel hybrid subframe
The reduction weight of effect, energy consumption is reduced, the different set structure arranged according to space, while effectively meeting functional requirement, cost
It is relatively low.
Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of changes, modification can be carried out to these embodiments, replace without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
