At present, the Control arm of car mainly is welded by sheet up and down, and its shortcoming is to be difficult to take into account strength and stiffness, and welding deformation is big, and accuracy of manufacture is poor, about can't be general.Recently the Control arm that a small amount of single chip architecture also occurred, but owing to adopt high strength steel, cost is higher, rigidity does not improve yet in addition, and the bulb hinge is installed is needed special riveting process, about part can not be general.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of intensity height, good rigidity, also can realizes the automobile Control arm that left and right Control arm exchanges.
The technical scheme that the utility model adopted is: a kind of automobile Control arm, comprise a body, an one constraint sleeve and a traction sleeve, this body has first end, second end and the 3rd end, the constraint sleeve is arranged on first end of body, the traction sleeve is arranged on second end of body, on this body, also be provided with a through hole, be characterized in, this body comprise by a steel disc be folded to form on, following two-layer steel disc and the bending section that is connected upper strata steel disc and lower floor's steel disc, this bending section is between second end and the 3rd end of body, and this bending section is provided with the folding groove of outside bending; Between first end of body and the 3rd end and upper strata steel disc and lower floor's steel disc between first end and second end be welded to connect.
Above-mentioned automobile Control arm, wherein, the hole wall of the through hole of body by a circle upper overturning and a circle down flange forms, first end of upper overturning and first end of following flange link to each other with the lower floor steel disc with the upper strata steel disc respectively, second end of upper overturning and second end of following flange are oppositely arranged; Second end that has one section following flange at least in the flange under the described circle forms flanging to described through hole one lateral buckling, and second end weldering of this flanging and upper overturning connects.
Above-mentioned automobile Control arm, wherein, the two ends periphery of traction sleeve is provided with outside flange.
The utility model has the advantages that:
1. the body of the utility model automobile Control arm is folded to form by a steel disc, can realize that left and right Control arm exchanges, and has saved manufacturing cost;
2. the body of the utility model automobile Control arm is provided with the folding groove of outside bending, and this folding groove can play the effect of reinforced rib, thereby has improved the strength and stiffness of automobile Control arm;
3. the utility model automobile Control arm mainly is being subjected to force direction folding, and all the other both directions adopt spot welding, can reduce welding deformation greatly;
4. the hole wall of the through hole of the utility model automobile Control arm is provided with flanging, can prevent that hole wall from collapsing, and makes things convenient for the trammel beam of suspension stabilizer rod to pass, and plays the effect of strengthening intensity simultaneously;
5. the two ends periphery of traction sleeve of the present utility model is provided with outside flange, can prevent the mistake circle that causes owing to welding traction sleeve.
Description of drawings
Fig. 1 is that the axle of the utility model automobile Control arm is surveyed scheme drawing;
Fig. 2 is the schematic top plan view of the utility model automobile Control arm;
Fig. 3 is the A-A line generalized section of Fig. 2;
Fig. 4 is the B-B line generalized section of Fig. 2;
Fig. 5 is the C-C line generalized section of Fig. 2.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is made and to be further specified.
See also Fig. 1 to Fig. 3.Automobile Control arm of the present utility model comprises a body 1, a constraint sleeve 2 and a traction sleeve 3.Body 1 has the first end 1a, the second end 1b and the 3rd end 1c, and constraint sleeve 2 is arranged on the first end 1a of body 1, and traction sleeve 3 is arranged on the second end 1b of body, also is provided with a through hole 10 on body 1.Preferably, the central axis z of constraint sleeve 2 and the central axis x coplane of traction sleeve 3, and vertical mutually.Body 1 comprises upper and lower two-layer steel disc that is folded to form by a steel disc and the bending section 13 that is connected upper strata steel disc 11 and lower floor's steel disc 12.Bending section 13 is between the second end 1b and the 3rd end 1c of body 1, and bending section 13 is provided with the folding groove 130 of outside bending.Folding groove 130 can play the effect of reinforced rib, thereby has improved the strength and stiffness of automobile Control arm.Upper strata steel disc 11 between the first end 1a of body 1 and the 3rd end 1c and between the first end 1a and the second end 1b is welded to connect with lower floor's steel disc 12, preferably, between the first end 1a of body 1 and the 3rd end 1c and the upper strata steel disc 11 between the first end 1a and the second end 1b and lower floor steel disc 12 be connected by spot welded mode.
As shown in Figure 4, the hole wall of the through hole 10 of body 1 is made up of flange 102 under a circle upper overturning 101 and the circle, first end of upper overturning 101 and first end of following flange 102 link to each other with lower floor steel disc 12 with upper strata steel disc 11 respectively, and second end of upper overturning 101 is oppositely arranged with second end of following flange 102.Second end that has one section following flange 102 at least in the flange 102 under a whole circle forms flanging 102a to through hole one lateral buckling, and second end weldering of flanging 102a and upper overturning 101 connects.Flanging 102a is set, can prevents that hole wall from collapsing, and make things convenient for the trammel beam of suspension stabilizer rod to pass, play the effect of strengthening intensity simultaneously.
Seeing also Fig. 5, is to prevent that the mistake that causes owing to welding traction sleeve 3 is round, is provided with outside flange 31 at the two ends periphery that draws sleeve 3.
