Abstract
The utility model relates to an auxiliary frame, comprising a left longitudinal beam and a right longitudinal beam, a front cross beam and a rear bow beam which are welded to form frame structure. Based on the frame structure, mounting parts of a front suspension system, such as a suspension control arm mounting frame, a steering engine mounting frame and a stabilizer bar mounting frame, etc. are added according to the arrangement requirement of the whole of an automobile. Meanwhile, auxiliary junction plates are added at the joints of four hollow beams for improving the reliability of the whole frame, the whole framed auxiliary frame assembly is connected with the automobile body through two conduits welded at the front ends of the left longitudinal beam and the right longitudinal beam and two punched holes at the rear ends. As seamless steel pipes are adopted as the left longitudinal beam and the right longitudinal beam and the rear bow beam, and square-tube sections are adopted as the front cross beam in the auxiliary frame, the processing technique and reliability are improved. The auxiliary frame is beneficial to the arrangement of a front bin of the whole automobile due to light weight and small occupy space thereof and can be flexibly adjusted by a tube bender due to being a pipe-bending fitting, thus achieving the purpose of effectively absorbing energy at the time of the collision of the whole automobile and improving the safety of the whole automobile.
Description
Technical field
The utility model relates to a kind of automotive suspension, relates in particular to a kind of shaped as frame subframe that is used for the independent front suspension system, the subframe that the product exemplar stage in a kind of automobile product development process that relates in particular to is used.
Background technology
In the prior art, automobile accessory frame, particularly auxiliary frame of passenger car adopts big-and-middle-sized die stamping cover panel more, constitute by welding by upper and lower two cover panels, its shortcoming is: 1. structure is comparatively complicated, globality is poor, causes the focal point of stress of whole subframe to increase large mold and the pressing equipment that needs input a large amount of.Because of relating to the exploitation of large mold, it is long therefore to produce the preparatory period.And the product exemplar stage in actual automobile product development process, manual exemplar was made difficulty because big-and-middle-sized blanked part, therefore this stage for exemplar is provided, how to have dropped into mould and finished the exemplar manufacturing, so development risk is big.In addition in the optimizing process of follow-up vehicle, when relating to the subframe change, need make amendment to mould, the cycle is long, have a big risk, so the change of such subframe is flexible poor.
Summary of the invention
The technical problems to be solved in the utility model is, changes the weak point of flexible difference in order to remedy existing automobile accessory frame, and a kind of compact conformation, manufacturing process simple possible, cheap for manufacturing cost are provided, and the change feasibility is the shaped as frame subframe flexibly.
The utility model is to solve the problems of the technologies described above to adopt following technical scheme: a kind of subframe, it comprises left and right longeron, front cross rail, back bow beam four part major parts, constitute the shaped as frame structure by welding, arrange that according to car load needs increase front suspension system installing components such as irs control arm mounting bracket, steering box mounting bracket, stabilizer rod mounting bracket on this shaped as frame architecture basics again.Simultaneously increased auxiliary connecting panel in order to improve the reliability of whole vehicle frame in the junction of four Guan Liang, whole shaped as frame subframe assembly links to each other with vehicle body by two conduits and rear end two punchings that are welded on the left-right longeron front end.
Good effect of the present utility model is that because left and right longeron of shaped as frame subframe structure and back bow beam adopt solid drawn pipe, front cross rail adopts square tube, is section bar.On the processing technology of tubing, utilize the section bar numerical control bender to replace expensive pressing equipment and large-scale mold tooling, thereby simplified tooling device greatly, reduced cost of development, improved the fabrication properties and the reliability of this shaped as frame subframe.Simultaneously this shaped as frame structure subframe in light weight than traditional subframe, take up room for a short time, help the preceding storehouse of car load and arrange.Subframe is having important effect aspect the car load driving safety, particularly aspect the car load collision, the trend of the left and right longeron of this shaped as frame subframe and the size at bending angle have material impact to it, cause is a bend pipe spare, so can adjust flexibly by pipe bending machine, the effect of effective energy-absorbing improves the car load safety when reaching the car load collision.
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Description of drawings
Fig. 1 is the utility model subframe organigram.
Among the figure: 1. left longeron body, 2. right vertical beam body, 3. bow beam body, 4. front cross rail body, 5. left connector bushing, 6. right connector bushing, 7. left back connecting bore, 8. right back connecting bore, 9. connecting panel, 10. left installation bracket, 11. right mounting brackets.
The specific embodiment
Embodiment as shown in Figure 1, a kind of subframe mainly comprises left longeron body 1, right vertical beam body 2, bow beam body 3, front cross rail body 4, left connector bushing 5, right connector bushing 6, left back connecting bore 7, right back connecting bore 8, connecting panel 9, left installation bracket 10, right mounting bracket 11.Left and right longeron body 1,2 is by front cross rail two ends connecting panel 9 weld togethers, and bow beam body 3 welds with left and right longeron 1,2 respectively simultaneously, is reinforced by mounting bracket 10,11 welding simultaneously, takes into account the installation effect.This moment, shaped as frame subframe agent structure was partly finished, and arranged the corresponding installing component of increase according to front suspension and preceding storehouse.After subframe assembly welding is finished, be to be connected with 7,8 four of left-right longeron rear end punchings and to finish by being welded on left and right sides connector bushing 5,6 on the left-right longeron body with body contact.
Left and right longeron of this shaped as frame structure and back bow beam adopt solid drawn pipe, and front cross rail adopts square tube, is section bar.On the processing technology of tubing, utilize the section bar numerical control bender to replace expensive pressing equipment and large-scale mold tooling, thereby simplified tooling device greatly, reduced cost of development, improved the fabrication properties and the reliability of this shaped as frame subframe.Simultaneously this shaped as frame structure subframe in light weight than traditional subframe, take up room for a short time, help the preceding storehouse of car load and arrange.Subframe is having important effect aspect the car load driving safety, particularly aspect the car load collision, the trend of the left and right longeron of this shaped as frame subframe and the size at bending angle have material impact to it, cause is a bend pipe spare, so can adjust flexibly by pipe bending machine, the effect of effective energy-absorbing improves the car load safety when reaching the car load collision.
