Abstract
The invention discloses an aluminum alloy automotive body skeleton which comprises a frame-type skeleton, wherein the frame-type skeleton comprises a longitudinal beam, a cross beam and an upright beam, which are mutually connected and assembled and are formed by aluminum alloy through extrusion. Compared with the conventional steel structure automotive body, the aluminum alloy automotive body skeleton disclosed by the invention is lower in the weight of the automotive body, so that the complete vehicle kerb mass is reduced, the oil consumption on the dead weight of the automobile is reduced, and the purposes of energy conversation and emission reduction are achieved. Meanwhile, the rigidity of the automotive body is also improved, a load-bearing structure is led to be concentrated on the mutually connected and assembled longitudinal beam, the cross beam and the upright beam, and furthermore, the safety of passengers in the automobile is guaranteed when the automobile is involved in a collision accident.
Description
Technical field
The present invention relates to the automotive body structure technical field, relate in particular to a kind of body framwork of aluminium alloy automobile.
Background technology
It is through to the steel punch forming that traditional automobile adopts the steel structure body framwork, welds assembly then, obtains being used for the skeleton structure of bearing automobile vehicle body.But traditional steel structure body framwork is owing to adopt steel, and own wt is heavier, has influenced complete vehicle curb weight, and fuel oil consumption is big.Punch forming process has high requirement to mould simultaneously, thereby has increased productive costs.On the other hand, near the mechanical characteristics suppression ratio the weld seam of welding back is more serious, causes the body framwork insufficient rigidity, when collision, can not guarantee occupant's safety.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the objective of the invention is to propose a kind of body framwork of aluminium alloy automobile, can reduce tare, increase body stiffness.
The object of the invention will be achieved through following technical scheme:
A kind of aluminium alloy automobile body framwork comprises the frame skeleton, and said frame skeleton comprises longeron, crossbeam and the Li Liang that interconnects assembly, and said longeron, crossbeam and upright beam are by aluminium alloy extruded moulding.
Preferably, above-mentioned aluminium alloy automobile body framwork, wherein: comprise also being used to seal the sheet member that supports said frame skeleton that said sheet member and said frame skeleton are riveted together.
Outstanding effect of the present invention is: aluminium alloy automobile body framwork of the present invention is compared with conventional steel structure vehicle body, has alleviated tare, thereby reduces complete vehicle curb weight, thereby the fuel oil consumption of minimizing on automotive dead weight reaches the purpose of energy-saving and emission-reduction.Simultaneously, also improve body stiffness, force structure has been concentrated on interconnect on longeron, crossbeam and the upright beam of assembly, in the time of collision happens, guaranteed occupant's safety.
Following constipation closes the embodiment accompanying drawing, and specific embodiments of the invention is done further to detail, so that technical scheme of the present invention is easier to understand, grasp.
Description of drawings
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment
Embodiment
A kind of aluminium alloy automobile body framwork of this enforcement, as shown in Figure 1, comprise the frame skeleton, the frame skeleton comprises longeron 1, crossbeam 2 and the upright beam 3 that interconnects assembly, longeron 1, crossbeam 2 and upright beam 3 are by aluminium alloy extruded moulding.Also comprise being used to seal the sheet member 4 that supports the frame skeleton, sheet member 4 is riveted together with the frame skeleton.
Present embodiment is compared with the conventional steel structure frame on material, replaces traditional steel by the lightweight aluminium material; Because the density of aluminium is far below steel, strength-to-density ratio is higher than steel, under the prerequisite that satisfies the vehicle body requirement; The weight of aluminium alloy automobile body framwork can be lighter, thereby reduce complete vehicle curb weight, reduces because the fuel oil consumption of automobile in deadweight; Realize energy-saving and emission-reduction, reduce the cost of maintaining the car simultaneously.Further, the aluminum alloy materials in the natural environment, owing to form the fine and close fire coat of one deck at its surface energy, this fire coat can stop oxygen and other gas, the invading the people of liquid and corrode.In case this fire coat is damaged, it can carry out self-regeneration quickly in most of environment, and is promptly excellent in antiseptic property.Structurally, through structure optimization, it is stressed that the body framwork of being made up of aluminum alloy is born vehicle body, guarantees body stiffness, and force structure is concentrated, and reduces the use of material, further reduces tare.The advocating and to bear by the longeron in the skeleton 1, crossbeam 2 and upright beam 3 of aluminium alloy automobile vehicle body framework construction; Easier controlled deformation zone and deformation tendency in collision process; Make driving compartment that sufficiently high rigidity arranged, when accident takes place, guarantee occupant's safety, and on vehicle body, can develop large stretch of hollow out zone and do not reduce body stiffness; Such as increasing the skylight configuration, can as traditional vehicle body, not reduce body stiffness.
The present invention still has numerous embodiments, and all employing equivalents or equivalent transformation and all technical schemes of forming all drop within protection scope of the present invention.
Claims (2)
1. an aluminium alloy automobile body framwork comprises the frame skeleton, it is characterized in that: said frame skeleton comprises longeron, crossbeam and the Li Liang that interconnects assembly, and said longeron, crossbeam and upright beam are by aluminium alloy extruded moulding.
2. aluminium alloy automobile body framwork according to claim 1 is characterized in that: comprise also being used to seal the sheet member that supports said frame skeleton that said sheet member and said frame skeleton are riveted together.
