Traditional lateral stability shaft bar, easily occurs that in intensity is calculated stress is concentrated (arc place is received in the welding starting the arc in Fig. 2, i.e. flange 16 and after cross member 8 lap-joints), rigidity is on the low side.For meet performance requriements generally needs steel plate is thickeied to about 3.5mm, thereby cause structure weightening finish, require not to be inconsistent with the light-weight design of structure.
Utility model content
The purpose of this utility model is to provide a kind of fore sub frame and crossbeam stabilizer bar arm thereof, and it can realize the requirement of product weight-saving.
For realizing the fore sub frame crossbeam stabilizer bar arm of described object, by a steel plate punched, formed, comprise front side sidewall, rear side sidewall and outside sidewall, front side sidewall, rear side sidewall and outside sidewall have flange respectively at bottom, this flange is for welding the after cross member of fore sub frame, be characterized in, also comprise upside sidewall and inside side walls, upside sidewall is and front side sidewall, rear side sidewall and outside sidewall are integral, and inside side walls is from upside sidewall downward bending, the bottom of inside side walls is also for the rear cross beam welding with fore sub frame, and with front, rear wall welds respectively.
Described fore sub frame crossbeam stabilizer bar arm, its further feature is, inside side walls is formed with respectively breach between the bending part of upside sidewall and forward and backward side sidewall.
Described fore sub frame crossbeam stabilizer bar arm, its further feature is that the bending part of upside sidewall and forward and backward side sidewall is formed with respectively reinforced rib.
Described fore sub frame crossbeam stabilizer bar arm, its further feature is that the thickness of described steel plate is 2.0mm.
For realizing the fore sub frame of described object, comprise after cross member, Panhard rod and the lateral stability shaft bar arranging respectively at after cross member two ends, lateral stability shaft bar is formed by a steel plate punched, comprise front side sidewall, rear side sidewall and outside sidewall, front side sidewall, rear side sidewall and outside sidewall have flange respectively at bottom, the after cross member of this flanging welded fore sub frame, be characterized in, lateral stability shaft bar also comprises upside sidewall and inside side walls, upside sidewall is and front side sidewall, rear side sidewall and outside sidewall are integral, and inside side walls is from upside sidewall downward bending, the bottom of inside side walls also with the rear cross beam welding of fore sub frame, and with front, rear wall welds respectively.
Described fore sub frame, its further feature is, inside side walls is formed with respectively breach between the bending part of upside sidewall and forward and backward side sidewall.
Described fore sub frame, its further feature is that the bending part of upside sidewall and forward and backward side sidewall is formed with respectively reinforced rib.
Described fore sub frame, its further feature is that the thickness of described steel plate is 2.0mm.
Aforementioned techniques scheme can be done lateral stability shaft bar thin, therefore can meet the requirement of product weight-saving.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of fore sub frame.
Fig. 2 is the block diagram of traditional lateral stability shaft bar.
Fig. 3 is the schematic diagram of lateral stability shaft bar in the utility model embodiment.
The specific embodiment
As shown in Figure 3, the Panhard rod mounting bracket of the utility model embodiment as shown in Figure 3, by a slice steel plate punched, formed, it comprises front side sidewall 21, rear side sidewall 22 and outside sidewall 23, also comprise upside sidewall 29 and inside side walls 27, the bottom of front side sidewall 21, rear side sidewall 22 and outside sidewall 23 has flange 26, has crossbeam stabilizer rod mounting hole 25 on forward and backward sidewall, with reference to Fig. 1, by flange 26, welds mutually with rear cross beam of subframe 8.
Upside sidewall 29 and front side sidewall 21, rear side sidewall 22 and outside sidewall 23 join and are integral, inside side walls 27 is from the downward flange of upside sidewall 29, inside side walls 27 is welded with the inner side of forward and backward sidewall 21,22, and also weld with after cross member 8 bottom of inside side walls 27.
At chamfering place or the bending part of inside side walls 27, and be formed with respectively breach 28 between forward and backward sidewall 21,22.
Chamfering place or bending part at upside sidewall 29 and forward and backward sidewall 21,22 are formed with respectively local reinforced rib 24.
In the utility model embodiment, Panhard rod mounting bracket is except welding by flange 26 and after cross member 8, also by inside side walls 27 and after cross member 8 welding.
With reference to Fig. 1 and Fig. 3, previous embodiment is to take the Panhard rod mounting bracket on right side of after cross member 8 to describe as example, but above stated specification is also suitable for the Panhard rod mounting bracket in left side simultaneously, and wherein inside side walls is than the sidewall of the more close after cross member of outside sidewall 8 inner sides.
In Fig. 3, the newly-designed lateral stability shaft bar lateral stability shaft bar traditional with Fig. 2 compared top, the inner side sealing of new support.Breach 28 can obviously improve the manufacturability of product, has also eliminated stress raisers simultaneously.
Inside side walls 27 is all welded with lateral stability shaft bar self and crossbeam 8, and lateral stability shaft bar just forms the box of a sealing like this, has better globality.
Contriver checks the Rigidity and strength of new support, and result of calculation shows that the rigidity of new construction all directions is all improved, and original conventional stent works the stress concentration phenomenon of receiving arc-welding place and substantially eliminates.Meeting same intensity and toughness requires the thickness of support to drop to 2.0mm by original 3.5mm.
Design plan after change has the advantages such as quality is light, location is convenient, technique is simple and easy to processing, easy assembling.
