Abstract
The invention provides an automobile rear independent suspension swing arm mounting bracket assembly, which is formed by welding a rear swing arm mounting board, a rear swing arm mounting and connecting board and a rear swing arm mounting and connecting board sealing board. A rectangular groove is punched in the middle of the cross section of the rear swing arm mounting board, wherein rectangularbosses of which the bottoms are provided with openings are symmetrically punched on two sides of the rectangular groove; a rectangular cavity of which the upside and the downside are provided with openings is respectively welded on the rear swing arm mounting and connecting board and the rear swing arm mounting and connecting board sealing board; the lower end of the rectangular cavity is welded in the rectangular groove in the middle of the rear swing arm mounting board, while the upper end is welded with a rear beam, so that the mounting bracket assembly and the rear beam form a closed cavity; and the end part of the rear swing arms are extended into the rectangular bosses on two sides of the rear swing arm mounting board and are then connected with the rear swing arm mounting board. The assembly has the advantages of high rigidity, simple part structure, simple process, low manufacturing cost, capability of better transferring the force transferred by the rear swing arm and improving the comfort of an automobile, and no deformation of a floor.
Description
Technical field
The present invention relates to automotive body structure, be specifically related to automobile rear independent suspension swing arm installation assembly structure.
Background technology
In existing common economy car, the rear independent suspension swing arm attachment point is to adopt support to install, and as depicted in figs. 1 and 2, this support b couples together by welding manner and rear-swing arm mounting rail a and after cross member c, and its shortcoming is:
When (1) on the bad road of jolting of being everlasting, travelling, rear-swing arm d conducts power to this support b, this support is the U type with floor, back point of attachment than weakness and rear-swing arm mounting rail, be unfavorable for the conduction of power, cause the back floor deformation bigger, even the point of attachment solder joint comes off, and influences occupant's traveling comfort, threatens occupant's personal safety.
(2) each support links together by welding and rear-swing arm mounting rail and floor, back, and the attachment point precision is difficult for guaranteeing, occurs the position, hole easily than large deviation, and problems such as difficulty are installed.
Summary of the invention
The invention reside in the deficiency that exists at prior art, a kind of automobile rear independent suspension swing arm mounting bracket assembly is provided, direct and osed top cavity of after cross member welding formation with this installation assembly structure, this structure is good rigidity not only, its design of part is simple, technology is simple, and cost of manufacture is low, and can better conduct the power that rear-swing arm transmits, the floor, back is not deformed, improve car comfort.
Technical scheme of the present invention is as follows:
A kind of mounting bracket assembly of automobile rear independent suspension swing arm, described mounting bracket assembly by rear swing arm mounting board, rear-swing arm connecting panel is installed and rear-swing arm installation connecting panel shrouding weld together constitutes; The middle punching press of the transversal surface that described rear swing arm mounting board is has a rectangular recess, and the punching press of rectangular recess bilateral symmetry has the rectangular boss of bottom surface opening; Described rear-swing arm is installed by connecting panel and rear-swing arm is installed the rectangular cavities that the connecting panel shrouding welds a upper and lower opening, the lower end of rectangular cavities is welded in the middle rectangular recess of rear swing arm mounting board, the upper end of rectangular cavities is used for being welded to connect with after cross member, makes mounting bracket assembly and after cross member form an osed top cavity; The end of described rear-swing arm puts in the rectangular boss of rear swing arm mounting board both sides, is connected with rear swing arm mounting board.
Further, also be welded with the rear swing arm mounting board shrouding, seal the bottom surface opening of the rectangular boss of rear swing arm mounting board both sides, form two little cavitys in the bottom surface of described rear swing arm mounting board.
The present invention can increase the rigidity of this structure by forming an osed top cavity with after cross member, when automobile is travelled on the bad road of jolting, can better conduct the power that rear-swing arm transmits, and the floor, back is not deformed, and improves car comfort.Especially further rear swing arm mounting board 3 and rear swing arm mounting board shrouding are also formed two little cavitys, can increase above effect more.And the rear-swing arm attachment point is all on this part of swing arm adapter plate, and the attachment point precision guarantees easily.Simultaneously, this is simple in structure, parts are regular, and cost of manufacture is low.

The specific embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
As shown in Figure 3 and Figure 4, this installation bracket assembly is made of rear swing arm mounting board 3, rear-swing arm installation connecting panel 2 and rear-swing arm installation connecting panel shrouding 1 weld together.
Referring to Fig. 6, rear swing arm mounting board 3 is long slab parts that a punching press forms, and there is a rectangular recess 31 centre of its transversal surface, and the rectangular boss 32 of bottom surface opening is arranged in rectangular recess 31 bilateral symmetry punching presses.Have on the rear swing arm mounting board 3 welding via hole, auxiliary hole and lightening hole, after this part only needs punching bending just, technology is simple, cost is low.
Referring to Fig. 5, rear-swing arm is installed the pressed sheet that connecting panel 2 is two ends bendings, and reinforced rib and auxiliary hole are arranged on it, and referring to Fig. 3, it and rear-swing arm are installed 1 welding of connecting panel shrouding, just form the rectangular cavities of a upper and lower opening.It is a kind of slab construction that rear-swing arm is installed connecting panel shrouding 1.
In conjunction with Fig. 7 as seen, the lower end of rectangular cavities is welded in the rectangular recess 31 of rear swing arm mounting board 3 centres, and the upper end of rectangular cavities and after cross member c are welded to connect, and makes mounting bracket assembly and after cross member c form an osed top cavity.
