Technical field
The utility model relates to a kind of automobile control arm.
Background technology
In automobile suspension system, Control arm has very high requirement as controlling the wheel alignment parameter of automobile in motion process and a safety member of transmitted load to its intensity, rigidity and reliability.In case Control arm lost efficacy, wheel will lose the location is connected vehicle body and will loses support with connection, have a strong impact on the stability of controlling of vehicle, very easily causes the accident of car crash.In the middle of existing mature technology, Control arm is many by casting, forging and blanked part welding moulding, and wherein the Control arm due to blanked part welding moulding is huge in advantage aspect lightweight, therefore also be most widely used.
Under the prerequisite that satisfies the intensity and toughness requirement, simultaneously in order to realize the Control arm lightweight, after being fastened by two blanked parts usually, the cross sectional shape of punching press welding class Control arm main body is welded into the rectangle structure of a sealing, in existing product structure welding process, welded gaps is crossed conference makes leg too high, the deflection of Control arm integral body increases, and occurs the phenomenon of rosin joint, solder skip when serious, affects accuracy of manufacture and the reliability of Control arm.If the adjustment weld gap can change the original sectional area of Control arm, the intensity of Control arm, rigidity can't guarantee.
The utility model content
The purpose of this utility model is to provide a kind of automobile control arm, overcomes that existing product is too high due to the leg that welded gaps causes greatly, distortion is serious and adjust the deficiency that weld gap can change the original sectional area of Control arm.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of automobile control arm, comprise Control arm main body and the shrouding that matches with this Control arm body, Control arm main body and shrouding are by being welded to connect, described Control arm main body comprises transverse concave groove, transverse concave groove front end side wall top is provided with inside flange, the middle part of transverse concave groove front end side wall is provided with opening, and transverse concave groove two ends are connected with respectively axle sleeve assembly one and ball pin assembly, and opening is connected with axle sleeve assembly two.
Further, described shrouding is provided with downward flange with the limit that Control arm body rear sidewall matches.
Further, the flat board of described shrouding for matching with the Control arm main body.
The beneficial effects of the utility model are: a kind of automobile control arm that the utility model provides, can satisfy the strength and stiffness requirement of Control arm, can satisfy again car load for the requirement of Control arm weight-saving, and welded gaps is adjustable in the middle of welding process, guaranteed greatly the reliability of welding quality and Control arm, simultaneously, the welding quality of Control arm reduces greatly to the sensivity of blanked part main body flange precision, has reduced accuracy requirement and the manufacturing cost of Control arm flange diel.

The specific embodiment
As shown in Fig. 1-5, the described a kind of automobile control arm of the utility model embodiment, comprise Control arm main body 1 and the shrouding 2 that matches with this Control arm body, Control arm main body 1 and shrouding 2 are by being welded to connect, described Control arm main body 1 comprises transverse concave groove 3, is provided with inside flange 4 above transverse concave groove 3 front end side wall, and the middle part of transverse concave groove 3 front end side wall is provided with opening, transverse concave groove 3 two ends are connected with respectively axle sleeve assembly 1 and ball pin assembly 6, and opening is connected with axle sleeve assembly 27; Described shrouding 2 is provided with downward flange 8 with the limit that Control arm main body 1 rear end sidewall matches; The flat board of described shrouding 2 for matching with Control arm main body 1.
As shown in Figure 6 and Figure 7, this Control arm is welded through welding bead after being fastened by main body and shrouding.Due to Control arm main body and shrouding by the steel plate punched moulding, in the middle of manufacturing process, the flange position of main body and shrouding can exist certain draft angle and resilience, make the angle [alpha] of flange and Control arm main body transverse plane greater than 90 °, thereby cause the welded gaps S of main body and shrouding to increase, welded gaps is crossed conference makes leg too high, and the deflection of Control arm integral body increases, the phenomenon that occurs rosin joint, solder skip when serious affects accuracy of manufacture and the reliability of Control arm greatly.If the employing stationary body, the overlap height H that adjusts shrouding adjusts weld gap S, can change the original sectional area of Control arm, and the intensity of Control arm, rigidity can't guarantee.
During use, first that Control arm main body 1 is fixing, shrouding 2 is fitted in the top of Control arm main body 1, wherein, downward flange 8 is positioned at the inboard of transverse concave groove 3 rear end sidewalls, and shrouding 2 is positioned at the top of inside flange 4, and 2 fastening place's welding make it to captive joint with shrouding in Control arm main body 1 afterwards, formation control arm welding assembly is being assembled into axle sleeve assembly 1, axle sleeve assembly 27 and ball pin assembly 6 respectively respectively on Control arm welding assembly at last.
As shown in Figure 8, when draft angle or the resilience of transverse concave groove 3 rear end sidewalls due to mould, make the angle [alpha] of the rear end sidewall of transverse concave groove 3 and base plate greater than 90 °, when causing the welded gaps S of Control arm main body 1 and shrouding 2 excessive, shrouding 2 sidewall one side is to the back-end suitably adjusted, until suitable welded gaps is arranged.Be far longer than the welded gaps S of transverse concave groove 3 rear end sidewalls this moment due to the amount of lap X of the straight flange end of shrouding 2 and inside flange 4, therefore still have enough amounts of lap to weld after shrouding 2 is adjusted, and shrouding 2 and Control arm main body 1 upper and lower to welded gaps unaffected, thereby make each locking edge of Control arm main body 1 and shrouding 2 that suitable welded gaps be arranged all the time, actv. has guaranteed welding quality and the reliability of Control arm.
In like manner, as shown in Figure 9, when shrouding 2 is flat board, regulate the adjusting that shrouding 2 can be realized the horizontal and vertical direction, thereby realize having all the time suitable welding gap.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation on its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
