Performance.Connection of the connection type of traditional steel vehicle body and steel chassis between steel and steel, can simply be welded, five it is large stretch of with
Welding procedure is relatively simple reliable when chassis is merged.However after using car body of aluminum alloy substitution steel body frame, the difference of material
Cause directly to weld the structure of the chassis bracket of car body of aluminum alloy skeleton and steel etc, for the work for being merged process
Bring certain difficulty.Therefore, it is necessary to the connection structures of a kind of aluminium vehicle body and steel chassis, for solving the full aluminium vehicle of full-bearing type
Materials variances is big when body and steel chassis are always spelled, is not easy to the defect of splicing, obtains safe and reliable connection structure.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of aluminium vehicle bodies connect with steel chassis
Structure connects car body of aluminum alloy skeleton and chassis bracket by adding steel plate, and structure is simple, safe and reliable, solves and holds entirely
Materials variances is big when load formula all-aluminium body and steel chassis are always spelled, is not easy to the defect of splicing.
The purpose of this utility model can be achieved through the following technical solutions：
The utility model provides a kind of aluminium vehicle body and steel chassis connection structure, including car body of aluminum alloy skeleton, chassis ox
Leg, steel plate, the car body of aluminum alloy skeleton are equipped with reserved hole location, the steel plate by pass through the flat head rivet of reserved hole location with
Nut is fastened on car body of aluminum alloy skeleton, and the chassis bracket is arranged in the inside of car body of aluminum alloy skeleton and is welded on steel plate
On.
Further, the material of the car body of aluminum alloy skeleton is 6061-T6.
Further, the steel plate with a thickness of 5mm, the material of steel plate and chassis bracket is Q345.
Further, the specification of the flat head rivet is GB70.3-M8 × 55.
The beneficial effects of the utility model：
(1) the aluminium vehicle body of the utility model and steel chassis connection structure, the steel plate of 5mm thickness is led to car body of aluminum alloy skeleton
After crossing flat head rivet and nut fastening, then on the steel plate by the welding of chassis bracket, so that the splicing of chassis bracket and aluminium vehicle body
Good, finally when large stretch of, chassis is merged, connection type is identical with the Joining Technology of traditional steel vehicle body and steel skeleton, structure letter
Single practical, for aluminium vehicle body stress level all within controlled level, body structure is safe and reliable when intensive analysis.
(2) thickness of steel plate is set as 5mm, and thickness is moderate, does not affect the appearance after the welding of chassis bracket；Steel plate and chassis ox
Leg uses Q345 material, and comprehensive mechanical property is good, and plasticity and weldability are good, has ensured the stability of body structure.
Detailed description of the invention
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the aluminium vehicle body and steel chassis attachment structure schematic diagram of the utility model；
Fig. 2 is the car body of aluminum alloy skeleton of the utility model and the attachment structure schematic diagram of steel plate；
Fig. 3 is the front view of the steel plate of the utility model；
Fig. 4 is the side sectional view of the steel plate of the utility model.
In figure：1, car body of aluminum alloy skeleton, 2, steel plate, 3, flat head rivet, 4, chassis bracket, 5, nut.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
All other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1 and Figure 2, a kind of aluminium vehicle body of the present embodiment and steel chassis connection structure, including car body of aluminum alloy skeleton
1, chassis bracket 4, steel plate 2, car body of aluminum alloy skeleton 1 are equipped with reserved hole location, and steel plate 2 reserves the tack riveting of hole location by passing through
Nail 3 is fastened on car body of aluminum alloy skeleton 1 with nut 5, and the inside of car body of aluminum alloy skeleton 1 and welding is arranged in chassis bracket 4
