Abstract
The utility model aims to provide an automobile auxiliary frame boundary beam welding assembly which has the characteristics of high performance and light weight. The automobile auxiliary frame boundary beam welding assembly comprises a boundary beam body formed by welding an upper boundary beam sheet and a lower boundary beam sheet and a sleeve connected to the boundary beam body, and is characterized by comprising an inner bracket, wherein the inner bracket is positioned in the lower boundary beam sheet and is welded on the lower boundary beam sheet; and two ends of the sleeve are welded on the inner bracket.
Description
Technical field
The utility model relates to the beam of automobile accessory frame.
Background technology
Fore sub frame is the important component part of car chassis, and its carrying driving engine and steering swivel system is connecting stabilizer rod, Control arm and vehicle body, is component part important in chassis system.
Traditional structure of front auxiliary frame is welded by front-axle beam 13, left and right side bar 11,12, the back rest 14 and each mounting bracket as shown in Figure 1.Front and rear beam 13,14 carries respectively the load of driving engine, steering box, stabilizer rod, the load of Control arm before and after left and right side bar 11,12 main carryings.
The tradition side bar for fluctuating plate 111,112 is welded to form, supports a sleeve 110 as shown in Figure 2 in the middle of the Control arm installation region before side bar, weld with side bar fluctuating plate 111,112 respectively at the two ends of sleeve 110.
Its performance of design vehicle subframe side bar is not good like this, easily loses efficacy at the sleeve connecting bridge.
The utility model content
The purpose of this utility model is to provide a kind of automobile accessory frame side bar welding assembly, and it has, and performance is strong, lightweight characteristics.
For realizing the automobile accessory frame side bar welding assembly of described purpose, comprise the side bar body that is welded by sheet under side bar upper slice and side bar, and be connected to sleeve on the side bar body, be characterized in, also comprise inner support, it is inner that inner support is positioned under side bar sheet, and be welded under side bar on sheet, and the two ends of described sleeve are welded on inner support.
Described automobile accessory frame side bar welding assembly, its further characteristics are that an end of described sleeve also is welded on side bar upper slice.
Described automobile accessory frame side bar welding assembly, its further characteristics are, this inner support comprises planar portions and the flange that forms from the bending of the relative both sides of planar portions, sleeve and described flange be quadrature mutually, on described flange, holding groove is arranged, described sleeve is accepted by the holding groove on flange, the outside of described sleeve and the welding of described holding groove.
Described automobile accessory frame side bar welding assembly, its further characteristics are that under the planar portions of this inner support and side bar, sheet is fitted and welded.
Described automobile accessory frame side bar welding assembly, its further characteristics are on the planar portions of this inner support, lightening hole to be arranged.
Described automobile accessory frame side bar welding assembly, its further characteristics be, describedly is welded as plug welding, is formed with plug welding hole under side bar on sheet.
When making the load of front Control arm be transmitted to side bar upper slice by sleeve, the design after improvement decomposes the position of sheet and inner support welding under side bar by inner support, the transmission of power disperses more, thereby obviously descend at side bar Control arm sleeve junction stress, the design plan after therefore improving has the advantages such as performance is strong, technique convenient, lightweight.

The specific embodiment
As shown in Figure 3 and Figure 4, in embodiment of the present utility model, the side bar body of fore sub frame is welded by sheet 22 under side bar upper slice 21 and side bar, automobile accessory frame side bar welding assembly also comprises inner support 23, inner support 23 is positioned at sheet 22 under side bar, and be welded under side bar on sheet 22, one end of sleeve 24 is welded on side bar upper slice 21 and two ends axle body downside is welded on inner support 23, such benefit is load to be spread out on sheet 22 under side bar by inner support 23, avoids stress to concentrate.
And in design as shown in Figure 2, the load of bearing in front Control arm hard spot position is directly transferred to side bar fluctuating plate 111,112 by sleeve 110, therefore side bar bears very large vertical, lateral action power, and consider lightweight and punching press requirement, side bar often can not be selected very thick punching, therefore area of stress concentration occurs in side bar Control arm sleeve junction, cause this area failures.Embodiment shown in Figure 3 just can overcome this problem.
With reference to Fig. 4, in an embodiment of the present utility model, the flange 232 that inner support 23 has planar portions 230 and forms by bending from the both sides of planar portions 230, sleeve 24 and the orthogonal thereto layout of flange 232.Form holding groove 234 in the middle of flange 232, be used for accepting sleeve 24, sleeve 24 and holding groove 234 welding, sheet 22 welding under the planar portions 230 of inner support 23 and side bar, for example be plug welding, as shown in Figure 3, correspondingly can form plug welding hole 220 at the corresponding part of sheet under side bar 22.Sleeve 24 firmly just is fixed on side bar inside by an inner support 23, three weld seams like this.
