Description
Technical field
The utility model relates to body of a motor car fields, and in particular to a kind of subframe longitudinal beam.
Background technique
Fore sub frame is the important component of vehicle bridge, main to connect vehicle body and engine, when front auxiliary car frame longitudinal beam designs,
In order to facilitate welding and guaranteeing weld strength, usual stringer is directly welded by upper and lower plates and is completed, and structure is too simple, so that stringer
Intensity, rigidity and collision effect be unable to satisfy requirement and subsequent be easy to appear fatigue cracking problem.
Therefore, in order to solve the above problem, a kind of subframe longitudinal beam is needed, can be improved the torsion stiffness of stringer, is realized vertical
Beam integral strength, the promotion of rigidity and the optimization of fatigue cracking problem solve.
Utility model content
In view of this, providing subframe longitudinal beam, Neng Gouti the purpose of the utility model is to overcome defect in the prior art
The torsion stiffness of high stringer realizes that stringer integral strength, the promotion of rigidity and the optimization of fatigue cracking problem solve.
The subframe longitudinal beam of the utility model, including stringer lower plate and stiffening plate, the stiffening plate is by the first stiffening plate,
Two stiffening plates and third stiffening plate splicing composition, each stiffening plate are arranged along the length direction of the stringer lower plate.
Further, the cross section of the stringer lower plate is in U-shape groove-like structure, and two cell walls extend outwardly equipped with flange.
Further, arch is convexed to form in the middle part of first stiffening plate, the second stiffening plate and third stiffening plate, it is cross-section
Face is in zigzag shape.
Further, the transverse sides of first stiffening plate, the second stiffening plate and third stiffening plate are and under the stringer
Two flange of plate are fixedly connected.
Further, the stiffening plate after the first stiffening plate, the second stiffening plate and third stiffening plate overlap joint by being welded to form.
Further, second stiffening plate is located in the first stiffening plate domes, and conformal fitting is welded in the
One stiffening plate;The third stiffening plate and the lap-joint of the first stiffening plate are conformal to be bonded and is welded and fixed.
Further, the third stiffening plate transverse sides offer location hole, and the first stiffening plate transverse sides are corresponding
Offer locating notch.
Further, first stiffening plate overlaps the integral rear slot bottom with the stringer lower plate with third stiffening plate and surrounds
Form the cavity of perforation.
The beneficial effects of the utility model are: a kind of subframe longitudinal beam disclosed by the utility model, is set by more stiffening plates
It sets, can be improved the torsion stiffness of stringer, realize stringer integral strength, the promotion of rigidity and the optimization solution of fatigue cracking problem
Certainly, avoid disposable manufacturing process requirement excessively high and bring manufacture problem.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model;
Fig. 2 is the explosive view of stiffening plate in the utility model;

To setting;Be arranged by more stiffening plates, can be improved the torsion stiffness of stringer, realize stringer integral strength, rigidity promotion with
And the optimization of fatigue cracking problem solves, and avoids disposable manufacturing process requirement excessively high and bring manufacture problem.
In the present embodiment, the cross section of the stringer lower plate 1 is in U-shape groove-like structure, and two cell walls extend outwardly and are equipped with
Flange;Conducive to the bending strength for increasing stringer lower plate 1, while the installation for being conducive to each stiffening plate is fixed.
In the present embodiment, the middle part of first stiffening plate 21, the second stiffening plate 22 and third stiffening plate 23 is convexed to form
Arch, cross section are in zigzag shape;While facilitating installation, it is conducive to increase structural strength.
In the present embodiment, the transverse sides of first stiffening plate 21, the second stiffening plate 22 and third stiffening plate 23 with
Two flange of the stringer lower plate 1 are fixedly connected;The stiffening plate is reinforced by the first stiffening plate 21, the second stiffening plate 22 and third
Plate 23 is welded to form after overlapping;Second stiffening plate 22 is located in 21 domes of the first stiffening plate, and conformal fitting
It is welded in the first stiffening plate 21;The third stiffening plate 23 and the lap-joint of the first stiffening plate 21 are conformal to be bonded and is welded and fixed;
Structural strength is high, and preparation is convenient.
In the present embodiment, 23 transverse sides of third stiffening plate offer location hole, and first stiffening plate 21 is laterally
Side correspondence offers locating notch;Facilitate location and installation.
In the present embodiment, first stiffening plate 21 overlaps the integral rear and stringer lower plate 1 with third stiffening plate 23
Slot bottom surround the cavity to form perforation;Conducive to the integrally-built weight of mitigation.
Finally, it is stated that above embodiments are merely intended for describing the technical solutions of the present application, but not for limiting the present application, although ginseng
The utility model is described in detail according to preferred embodiment, those skilled in the art should understand that, it can be to this
