Abstract
The utility model is related to a kind of fore sub frame reinforcing plate structure, including butterfly fore sub frame, it is characterised in that：The top of body portion is provided with reinforcing plate under fore sub frame, and the both sides of reinforcing plate are provided with the type face with this mates under fore sub frame, and described type face is located under the inner side of body under fore sub frame, reinforcing plate and fore sub frame between body by being welded and fixed.
Description
Technical field
The utility model is related to a kind of fore sub frame reinforcing plate structure.
Background technology
Automobile front subframe is the carrier of the major assemblies of automobile, is important stressed member.Fore sub frame will be held when working
The moment of flexure and shearing force that a variety of load are produced such as reversed, bent, in actual driving conditions, fore sub frame will also by from
The excitation on road surface and the excitation of engine, have to consider to have enough intensity, enough bending rigidities and suitable in design
Torsional rigidity, it is ensured that the adaptability of automobile road pavement unevenness, and rational vibration characteristics is also highly important.Existing vapour
Chinese herbaceous peony subframe rigidity, insufficient strength, and automobile easily produces resonance between each part in use, causes some portions
The earlier period damage of part, reduces the service life of automobile, the comfortableness that influence passenger drives.When the vehicle first-order modal of fore sub frame
With the driving frequency under engine normal revolution very close to when, the driving frequency of subframe and engine resonates, and vehicle is just
Roar can be produced, the service life of automobile is reduced, the comfortableness of passenger is influenceed, at this moment needs to body structure or subframe
Structure is changed greatly, and to improve first-order modal of the subframe under vehicle, but these implementation method costs are very high, exploitation week
Phase is very long, directly affects the development progress of whole project.
Utility model content
Goal of the invention of the present utility model is to provide a kind of fore sub frame reinforcing plate structure, can strengthen fore sub frame
Intensity, rigidity, increase the service life.
Realize the technical scheme of the present utility model purpose：
A kind of fore sub frame reinforcing plate structure, including butterfly fore sub frame, it is characterised in that：
The top of body portion is provided with reinforcing plate under fore sub frame, and the both sides of reinforcing plate are provided with and body under fore sub frame
The type face being engaged, described type face is located under the inner side of body under fore sub frame, reinforcing plate and fore sub frame to be passed through between body
It is welded and fixed.
Further, reinforcing plate is provided with two reinforcements, respectively positioned at the left part and right part of reinforcing plate.
Further, reinforcing plate top carries flange.
Further, reinforcing plate is provided with welding positioning hole.
The utility model has the advantage that：
The top of the utility model body portion under fore sub frame is provided with reinforcing plate, and the both sides of reinforcing plate are provided with and preceding pair
The type face of this mates under vehicle frame, described type face is located at the inner side of body under fore sub frame, reinforcing plate and lower of fore sub frame
By being welded and fixed between body.The utility model reinforcing plate is located at the bottom of the anterior main Path of Force Transfer of butterfly subframe, i.e.,
Reinforcing plate is located at subframe body under damped condition and is primarily subjected on load section, and reinforcing plate passes through welding and lower of fore sub frame
Body front portion is fixed, subframe has not both been interfered with so with the clearance requirement between dynamic total, suspension, while can also increase subframe master
The strength and stiffness in Path of Force Transfer are wanted, and ensure first-order modal of the subframe under vehicle, it is ensured that subframe will not be torn,
Its strength and stiffness requirement need not be ensured by making complex profile to the change of subframe body.The utility model reinforcing plate
Provided with two reinforcements, respectively positioned at the left part and right part of reinforcing plate；Reinforcing plate top carries flange, before further increasing
The rigidity and intensity of subframe.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model reinforcing plate is installed on fore sub frame；
Fig. 2 is the structural representation of the utility model reinforcing plate.
Embodiment
As shown in figure 1, the anterior top of body 2 is provided with reinforcing plate 1 under butterfly fore sub frame, as shown in Fig. 2, Fig. 1, plus
The both sides of strong plate are provided with the type face 4 with this mates under fore sub frame, and described type face 4 is located at the interior of body 2 under fore sub frame
By being welded and fixed between body under side, reinforcing plate 1 and fore sub frame, as shown in figure 1, reinforcing plate 1 and body under fore sub frame
Between junction weld seam 3.As shown in Fig. 2 reinforcing plate is provided with welding positioning hole 6, reinforcing plate is provided with two reinforcements 5,
It is located at the left part and right part of reinforcing plate respectively.Reinforcing plate is molded using general steel plate punched, as shown in Fig. 2 reinforcing plate
With flange 7, to strengthen the intensity of itself.
Obvious the utility model, which is implemented, to be not subject to the restrictions described above, as long as employing method of the present utility model
The improvement for the various unsubstantialities that design and technical scheme are carried out, within protection domain of the present utility model.
