Along with the development of auto industry, automobile has become as an indispensable part in people's life.Automobile is pacified
Full property is increasingly subject to people's attention, especially Crash Safety Design of Vehicles energy.
Automobile front subframe is the load-carrying unit that automobile chassis system is important, is the important safety knot in automobile chassis system
Structure bogey, for stabiliser bar, turns to the parts such as machine, engine mounting, swing arm to provide the important support structure of installation site,
Bear turning in running car, brake and the load such as vertical.Therefore, the performance such as the intensity of automobile front subframe, rigidity has
Important effect, the rigidity of himself, intensity directly influence safety and the riding comfort of car load.
In vehicle traveling process, once occur acting laterally on the side force of fore sub frame along automobile, at collision knot
The join domain of structure and fore sub frame can produce serious transverse curvature.This flexural deformation makes the position of fore sub frame change
Become, totally unfavorable to the steering behaviour of automobile.Accordingly, it would be desirable to improve the transverse curvature rigidity of automobile front subframe, strengthen automobile
The security performance of front end.
If transverse curvature insufficient rigidity at automotive front, especially fore sub frame, big change in use occurs
Shape, then can badly influence the serviceability of brakes and steering.Especially during running at high speed, if vapour
Herba Plantaginis subframe portion structure lost efficacy and easily lead to car crash, it is therefore necessary to automobile front subframe portion structure to be ensured is full
Foot intensity and toughness performance requirement.
The generally both sides, front end at fore sub frame arrange collision energy-absorbing device, and this structure occurs complete front to touch at vehicle
When hitting more effective.But reality practical situation, the situation of complete head-on crash is less, and majority of case is all non-fully front
Collision.Therefore, this fore sub frame device is when bias state collides, it is impossible to fully offset collision energy.In order to ensure
The control stability of automobile and driving safety, it is desirable to automobile front subframe to have enough rigidity, intensity and endurance qualities, makes
Obtain automobile and can meet use requirement in whole life cycle.
Traditional fore sub frame, in order to ensure its stiffness and strength performance, often presents maximization, thus causes weight big, knot
Structure complexity manufacturing cost is high.Subframe is connected with crash feature, absorbs local collision energy.At offset collision or angle collisions
Time, body forward structure bending stiffness wretched insufficiency.
In the case of how meeting intensity and toughness requirement, alleviate the weight of fore sub frame, save production cost, it is provided that performance
The structure of front auxiliary frame that preferably structure is more excellent becomes the emphasis of automobile chassis systematic study, improve running car comfortableness with
And handling conveniently plays an important role.

Detailed description of the invention
Below against accompanying drawing, by the description to embodiment, the detailed description of the invention of the present invention is made further details of
Illustrate, to help those skilled in the art that inventive concept, the technical scheme of the present invention are had more complete, accurate and deep reason
Solve.
Automobile front subframe is the vital structure of automobile chassis system, and its structure is complicated, and difficulty of processing is relatively big, because of
This, when fore sub frame being improved overall transverse curvature rigidity property, it is necessary to based on lightweight and optimized thinking, must
Simple in construction must be ensured, it is easy to accomplish, production and processing is convenient, and crudy is prone to ensure.
The present invention is to provide the web beam structure improving automobile front subframe transverse curvature rigidity, with simple and effective
Structure is just
The support automobile front subframe that energy is stable, and can sufficiently guarantee front portion of car body transverse curvature rigidity.
The present invention
Automobile front subframe web beam scientific structure design is reasonable, and the structure that can well improve automobile front subframe is steady
It is qualitative,
Simple in construction is easily achieved, and manufactures production cost low.
As it is shown in figure 1, be automobile front subframe web beam structure of the present invention, the agent structure of described fore sub frame is
The front subframe upper plate 1 being welded to each other and fore sub frame lower plate 2.
In order to solve the problem of prior art existence and overcome its defect, it is achieved solve existing front portion of car body the most curved
The goal of the invention of the problem that stiffness is not enough, the technical scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, the automobile front subframe web beam structure of the present invention, described web beam structure sets
