Abstract
The utility model provides a back sub vehicle puts up connecting rod, back sub vehicle puts up connecting rod includes connecting rod body and two bush sleeves, the bush sleeve is connected respectively the both ends of connecting rod body, the both sides face of connecting rod body sets up the profile into U, the edge of U profile is equipped with the turn -ups. The utility model discloses back sub vehicle puts up connecting rod's structure is by the cylindrical U type flange structure that changes into, and both ends are longer with the welding seam of muffjoint, and bearing capacity is stronger, has reduced the regional stress concentration of welding seam. It has advantages such as the location is convenient, simple process is workable, just easy assembly, and is also comparatively outstanding in the aspect of performances such as intensity moreover.
Description
Technical field
The utility model relates to automotive field, particularly a kind of Rear secondary frame for vehicle connecting rod.
Background technology
In existing automotive field, multi link formula Rear secondary frame for vehicle relies on front-rear linkage to subject the various load brought in running car, and its intensity is the important indicator of test product design.
Fig. 1 is the structural representation of traditional Rear secondary frame for vehicle connecting rod.As shown in Figure 1, described Rear secondary frame for vehicle connecting rod connects two liner sleeve 20 by an elongated hollow connecting rod 10 and is formed, and is connected between connecting rod 10 and liner sleeve 20 by the form of welding.When stand under load, connecting rod 10 produces larger stress with the weld seam peripheral region of liner sleeve 20 and concentrates, and may cause the risk that part breaking lost efficacy.Conventional linkage assembly structure is single, and between sleeve and connecting rod, fusion length is connecting rod girth, and because girth is limited, therefore the lap-joint of weld metal zone is easy to occur stress concentration phenomenon.
In this case, if directly increase the thickness of connecting rod 10 or liner sleeve 20, then the weight of Rear secondary frame for vehicle can be made to increase, weight-saving requirement cannot be met.Therefore, in order to meet performance requriements, traditional bar linkage structure needs to carry out structure optimization, such as, change the joint form between connecting rod 10 and liner sleeve 20, concentrates with the stress of the weld seam peripheral region of liner sleeve 20 to reducing connecting rod 10.
Utility model content
The technical problems to be solved in the utility model is that the join domain stress in order to overcome Rear secondary frame for vehicle connecting rod in prior art is concentrated, and easily causes the defect that part breaking lost efficacy, provides a kind of Rear secondary frame for vehicle connecting rod.
The utility model solves above-mentioned technical matters by following technical proposals: a kind of Rear secondary frame for vehicle connecting rod, its feature is, described Rear secondary frame for vehicle connecting rod comprises con-rod only and two liner sleeve, described liner sleeve is connected to the two ends of described con-rod only, the two sides of described con-rod only are set to U-shaped, and the edge of described U-shaped is provided with flange.
Preferably, the height of described U-shaped is 20-30mm.
Preferably, the lap of splice between described con-rod only and described liner sleeve is 1/2nd of the girth of described liner sleeve.
Preferably, the width of described flange is 3-5mm.
Preferably, the upper surface upper punch of described con-rod only is pressed with reinforced rib.
Preferably, the width of described reinforced rib is 10-15mm.
Preferably, the two ends of described reinforced rib are 20-40mm apart from the distance at the two ends of described con-rod only.
Positive progressive effect of the present utility model is:
The structure of the utility model Rear secondary frame for vehicle connecting rod changes U-shaped turnup structure into by cylindrical, and the weld seam of two ends and sleeve connection is longer, and load-carrying capacity is stronger, and the stress reducing welded seam area is concentrated.It has, and location is convenient, technique is simple and easy to processing and is easy to the advantages such as assembling, and also comparatively outstanding at aspect of performances such as intensity.
Accompanying drawing explanation
The above and other feature of the utility model, character and advantage are by more obvious by what become below in conjunction with the description of drawings and Examples, and Reference numeral identical in the accompanying drawings represents identical feature all the time, wherein:
Fig. 1 is the structural representation of traditional Rear secondary frame for vehicle connecting rod.
Fig. 2 is the structural representation of the utility model Rear secondary frame for vehicle connecting rod.
Detailed description of the invention
For above-mentioned purpose of the present utility model, feature and advantage can be become apparent, below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
With detailed reference to accompanying drawing, embodiment of the present utility model is described now.Now with detailed reference to preferred embodiment of the present utility model, its example is shown in the drawings.In the case of any possible, in all of the figs the identical mark of use is represented same or analogous part.In addition, although the term used in the utility model selects from public term, but some terms mentioned in the utility model specification sheets may be that applicant selects by his or her judgement, its detailed meanings illustrates in the relevant portion of description herein.In addition, require not only to pass through used actual terms, but the meaning that also will be contained by each term understands the utility model.
Fig. 2 is the structural representation of the utility model Rear secondary frame for vehicle connecting rod.As shown in Figure 2, a kind of Rear secondary frame for vehicle connecting rod 30 is disclosed in an embodiment of the present utility model, it comprises con-rod only 31 and two liner sleeve 32, liner sleeve 32 is connected to the two ends of con-rod only 31, and the two sides of con-rod only 31 are set to U-shaped face 33, the edge in U-shaped face 33 is arranged flange 34.
The height in U-shaped face 33 is here preferably 20-30mm.The lap of splice between con-rod only 31 and liner sleeve 32 is 1/2nd of the girth of liner sleeve 32.The width of flange is preferably 3-5mm, effectively can increase the intensity of con-rod only 31.
In addition further, reinforced rib 35 is pressed with in the upper surface upper punch of con-rod only 31.The width of reinforced rib 35 is preferably 10-15mm.The two ends of reinforced rib 35 are 20-40mm apart from the distance at the two ends of described con-rod only.Reinforced rib 35 had both added the arrangement intensity of con-rod only 31, too increased rigidity.
In sum, the structure of the utility model Rear secondary frame for vehicle connecting rod changes U-shaped turnup structure into by cylindrical, and the weld seam of two ends and sleeve connection is longer, and load-carrying capacity is stronger, and the stress reducing welded seam area is concentrated.Design plan after this change has location convenience, technique is simple and easy to the advantage such as processing, easy assembling, also comparatively outstanding at aspect of performances such as intensity.
Although the foregoing describe detailed description of the invention of the present utility model, it will be understood by those of skill in the art that these are only casehistorys, protection domain of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these change and amendment all falls into protection domain of the present utility model.
