Abstract
An auxiliary frame with plug welding groove structures for strengthening comprises a front beam and a back beam which are welded together and a left longitudinal beam and a right longitudinal beam which are welded together. A front support of an engine is welded on the front beam, a back support of the motor is welded on the back beam, a control arm support is welded on the right longitudinal beam, connection portions of the back beam and the left longitudinal beam and the right longitudinal beam are provided with stabilizer bar installing holes, the plug welding grooves for strengthening are close to the stabilizer bar installing holes, the back beam is welded with the left longitudinal beam and the right longitudinal beam through the plug welding grooves for strengthening respectively.
Description
Technical field
The utility model relates to automobile accessory frame.
Background technology
Subframe is important safety part and the load member in the car chassis system, and its intensity, rigidity, fatigue etc. all have high requirement, is bearing turning in the running car, braking and vertical load.The intensity of subframe, rigidity, fatigue etc. directly have influence on safety, travelling comfort of car load etc.
Tradition stamping-welded automobile accessory frame structure is as shown in Figure 1, is welded by front and rear beam 1,4 and left- right longeron 7,8, according to the trim designs needs of car load, is welded with several supports 2,3,5 and is used to support suspension system, power plant module, pipeline etc. simultaneously.
Tradition stamping-welded automobile accessory frame to the position insufficient rigidity of the back rest 4 with the contiguous stabilizer rod mounting hole 6 in left and right beam 7,8 junctions, can solve through increasing structures such as reinforced rib or reinforced sheet in design.But this need look the permission of assembly space, perhaps can increase product weight, thereby increases cost, and has quality problems such as welding deformation.
The utility model content
The purpose of the utility model is to provide a kind of subframe to strengthen with plug welding groove structure, and it does not influence the enveloping surface and the assembling of part, does not increase the quality of part, quality problems such as cause that the welding location is forbidden again.
For realizing the subframe of strengthening with plug welding groove structure that has of said purpose; The forward and backward beam and the left and right longeron that comprise weld together; Front-axle beam welding engine bracket of sandwich mounting is welded with engine rear support on the back rest, be welded with the Control arm support on the right vertical beam; The junction of the back rest and left and right longeron has stabilizer rod mounting hole and contiguous stabilizer rod mounting hole to have reinforcement to use the plug welding groove, and the back rest comes plug welding to be connected through reinforcement with the plug welding groove respectively with left and right longeron.
The aforementioned techniques scheme through at the back rest and left and right beam connecting portion insufficient rigidity place through increasing the structure of plug welding groove; Solve the not enough problem of local stiffness; Make the rigidity value at this place can increase about 10%; Simultaneously plug welding groove structure does not promptly influence the enveloping surface and the assembling of part, do not increase again part quality, cause quality problems such as the welding location is inaccurate.
Description of drawings
Fig. 1 is the structural representation of existing subframe.
Fig. 2 is the structural representation of the subframe of the utility model.
The specific embodiment
As shown in Figure 2; Subframe comprises the forward and backward beam 10,40 and the left and right longeron 70,80 of weld together; Front-axle beam 10 welding engine bracket of sandwich mountings 20; Be welded with engine rear support 50 on the back rest 40; Be welded with Control arm support 30 on the right vertical beam 80, the junction of the back rest 40 and left and right longeron 70,80 has stabilizer rod mounting hole 60 and contiguous stabilizer rod mounting hole 60 reinforcement to be arranged with plug welding groove 90, and the back rest 40 all by means of strengthen with plug welding groove 90 comes plug welding be connected through reinforcement with plug welding groove 90 with left and right longeron 70,80.
