The specific embodiment
As shown in Figure 1 to Figure 3, later bracket of trailing arm 1 is assembled into example with left and right vehicle body, and the vehicle body bracket of trailing arm mounting structure of the present embodiment is described.A kind of vehicle body bracket of trailing arm mounting structure, comprise floor side member 6, left back wheel cover 4, left-side 5, rear shock absorber seat 7, vehicle body outermost layer adapter plate 3, interior of body connecting panel 9 and for fastening bolt 2, vehicle body outermost layer adapter plate 3 is provided with the bolt hole that allows bolt 2 pass, interior of body connecting panel 9 is welded to connect with floor side member 6, and vehicle body outermost layer adapter plate 3 is for being positioned at an adapter plate in interior of body connecting panel 9 outsides on vehicle body.
This mounting structure also comprises the reinforced support 8 being located between vehicle body outermost layer adapter plate 3 and interior of body connecting panel 9, the trapezium structure of reinforced support 8 for being bent to form by sheet material, the side plate 12 that comprises the both sides that middle deck 11 is relative with being located at middle deck 11, between side plate 12 and middle deck 11, there is a bending, the end of side plate 12 is provided with flange 13, between flange 13 and side plate 12, also there is a bending, therefore reinforced support 8 has bending everywhere altogether, middle deck 11 above, two flange 13 below, the end face of middle deck 11 contacts with vehicle body outermost layer adapter plate 3, middle deck 11 is connected with the panel beating spot welding of body exterior near bracket of trailing arm, flange 13 is below connected with 9 spot welding of interior of body connecting panel.Middle deck 11 is provided with the bolt hole 10 that allows bolt 2 pass, and bolt hole 10 is provided with two altogether, and two bolts hole 10 are located at the midway location of middle deck 11 side by side.Technique for reinforced support 8, than being easier to, realize, before punching press, the size of panel beating can be good according to the limit design in concrete body structure and space, forms four road bendings after punching press, notices that bending fillet requires as far as possible little under the prerequisite that meets Sheet Metal Forming Technology reliability.The width of middle deck 11 will guarantee that its upper bolt hole 10 is enough to the spacing of middle deck 11 bending edges, do not occur that excessive combined stresses concentrates that (bolt hole limit and bending edges are all areals of stress concentration, can not lean on too near), on this basis, the width requirement of middle deck 11 is as far as possible little.As for the length of reinforced support 8, there is no need oversize, as long as guarantee that bolt hole 10 is to the hole back gauge of reinforced support 8 length direction edges at two ends enough (fatigue cracking may appear in too small hole back gauge).Middle deck 11 requires more than two with the solder joint of vehicle body sheet metal, only needs to guarantee that location is fixing, and these solder joints do not need to bear load.As long as the width of bottom flange 13 can meet single spot welding, require just much of that.The thickness of support panel beating can be according to the flexible in size design of bolt hole 10 place's load, material selection steel.
The object that reinforced support 8 is designed to trapezium structure is to have used dexterously film stand under load principle, and the key problem in technology of the reinforced support 8 of this trapezium structure is the width of middle deck 11 of flap and the design of the distance of bottom two flange 13.The width requirement of middle deck 11 is being stopped bolt hole 10 to as far as possible little on the basis of the spacing of upper brace bending edges, the position of bottom flange 13 will be designed to be positioned at the place that strengthen box rigidity is larger as far as possible, mutually at regular intervals, bottom two flange 13 are designed to be positioned at respectively the both sides of upper brace conventionally.Guaranteeing on the basis that has enough rigidity of support bottom flange 13 like this, make the load of support upper brace two flange 13 to bottom transmit similar film carrying, Bending Internal Force is less, and stress be take evenly draw/compression effort as main, material use efficiency is higher, and intensity is very high.
This mounting structure also comprises and the bolt collar 14 of bolt 2 for being threaded, in the bolt hole of one end insertion vehicle body outermost layer adapter plate 3 of bolt collar 14, be fixedly connected with vehicle body outermost layer adapter plate 3, the other end is fixedly connected with interior of body connecting panel 9, and bolt collar 14 is also fixedly connected with middle deck 11 through the bolt hole 10 in middle deck 11.The pulling force of bolt 2 passes to inside link plate and vehicle body outermost layer adapter plate 3 by bolt collar 14, pass to reinforced support 8 simultaneously, the pressure of Rear drag arm support 1 boss passes to vehicle body outermost layer adapter plate 3, pass to reinforced support 8 simultaneously, then pass to inside link plate by bolt collar 14.The various concentrated stand under load that reinforced support 8 can meet towing arm bolt 2 places simultaneously requires---and when bolt 2 is subject to pulling force, bolt collar 14 is extruding vehicle body sheet metal outwards, and now this reinforced support 8 is subject to pulling force to bear this load, transfers loads to inside link plate.If run into the foundry goods bracket of trailing arm of strap bolt hole boss, bolt hole place can be stressed, and reinforced support 8 is stressed and bears this load, transfers loads to inside link plate.Therefore, the main mechanics of reinforced support 8 is worth and is to have increased a Path of Force Transfer, and the concentrated load at bolt 2 places is delivered on the lower interior of body connecting panel 9 of underusing its value of stress typically.
This mounting structure has the following advantages:
1. use the folded structure meet film stand under load principle, the understressed region that is distributed to by larger concentrated load in the mode of pure tension and compression, stressed ingenious rationally, structural strength is very high;
2. structure is small and exquisite, can adapt to the compact narrow and small feature in vehicle body bracket of trailing arm attachment point space, and weight is very low, is easy to manufacture, with low cost;
3. be easy to design, strong adaptability, can well adapt to various scantling of structure, convenient for assembly, only by several solder joints, connects, and without freezing, reliability is higher.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
