Abstract
The utility model aims at providing an automobile control arm, which is easier to be machined. In order to achieve the automobile control arm, a main body is obtained by connecting upper and lower stamped sheet bodies; and the automobile control arm is characterized in that the connecting mode between the upper and lower sheet bodies is rivet free riveting.
Description
Technical field
The utility model relates to the automobile Control arm.
Background technology
Automobile Control arm (Control arm also claims swing arm) passes to vehicle body as the guiding and the force transfer element of automobile suspension system with the various power that act on the wheel, guarantees that simultaneously wheel presses certain track motion.The automobile Control arm respectively through ball pivot or lining wheel and flexible chassis link together.
Existing two-piece type Control arm (being made up of upper body and lower body two parts) after the punch forming of upper body and lower body difference, generally adopts spot welded mode will go up lower body and combines in manufacturing process.But there is following disadvantage in spot welded mode.
1, online detection is difficult for.Spot welded main online detection mode is for chiseling the power test, and this test can't be used in online detection for destructive test high-frequency.
2, component surface is required height.Because spot welded process technology limit, it is had relatively high expectations to component surface.Be used for spot welded component surface and do not allow to exist open defects such as greasy dirt, oxide skin, otherwise will influence spot welded quality widely.
3, machining period is longer.Spot welded processing technology has determined spot welding to need certain holding the pressure time, meanwhile since the spot welding robot extremely difficulty accomplish to process simultaneously a plurality of solder joints, therefore influenced its overhours greatly.
4, be difficult to realize flexible processing.Present large batch of spot welding robot processes according to the program that weaves in advance adding man-hour, and the workpiece of processing need be fixed through welding jig simultaneously; Therefore, change another kind of product, must change welding jig like need; And the adjustment welding track, be difficult to realize Flexible Production.
The utility model content
The purpose of the utility model is to provide a kind of automobile Control arm, and it is processed more easily.
For realizing the automobile Control arm of said purpose, its body is formed by connecting stamping forming upper and lower lamellar body, is characterized in, the connection mode of upper and lower lamellar body is no rivet.
No rivet is as a kind of state-of-the art plate interconnection technique; It is to be applied to thin plate to connect; Those skilled in the art it has been generally acknowledged that because the sheet metal thickness of car chassis part is thicker; Therefore, this area does not have the precedent of utilizing no rivet to connect making automobile Control arm before the application.And the contriver proposes the aforementioned techniques scheme based on following discovery:
1, Control arm is main with spot welding, little arc-welding;
2, Control arm material stretch ratio is high, is easy to riveting molding;
3, riveted joint place is the plane, is easy to riveting molding.
4, for all the other chassis parts; Because most of parts all use arc-welding to connect, or its junction is curved surface, therefore; Be not easy to use no rivet technology; Part material stretch ratio is lower or sheet material is thicker, is prone to during riveted joint crack, and the intensity and the rigidity of product itself is exerted an influence.
Because the online detection means of no rivet is riveted the degree of depth for detecting it, so the no rivet of the utility model utilization, the making flow process of Control arm is by original: arc-welding-spot welding 1-spot welding 2-press-fits, and changes to: riveted joint-arc-welding-press-fit.Wherein, arc-welding and press-fit in original Control arm technology consistently substitutes original spot welding by riveted joint and makes, and the riveted joint position was with originally the spot welding position was identical.
In addition; At present the car chassis part presents hardware and software platform trend, diverse trends, to the flexibility of manufacturing line and production time require increasingly high; With respect to traditional spot welding technology, no rivet connection mode makes the automobile Control arm also have several some advantage down:
1, compares with spot welding, do not have the distortion of connection;
2, the Joint strenght of single-point is higher by 70% than spot welding, adopts no rivet technology that the sheet up and down of Control arm is linked together.No matter this technology is from static strength or dynamic strength, all above common spot welding;
3, connection procedure can be monitored automatically, compares with spot welding, and measuring means is simpler and easy, and realizes on-line monitoring easily;
4, material is extruded reinforcement at the point of connection place, does not have and tears damage;
5, do not damage the coating or the enamelled coating of plate surface, point of connection keeps the original resistance to corrosion of plate;
Even 6 in extremely narrow flange or very little space, also can perfectly connect;
7, need not heating in the connection procedure;
8, be prone to realize flexibility processing.
Description of drawings
Fig. 1 is the scheme drawing of automobile Control arm.
The specific embodiment
Fig. 1 shows a kind of automobile Control arm, for automobile suspension system laterally lead arm, its body 1 is formed by connecting upper and lower lamellar body, the two ends of a side of body 1 are connected with lining and sleeve 2 respectively, the end of opposite side is connected with bulb 3.The connection of its middle sleeve is to connect through arc-welding, and the connection mode of bulb and lining connects for assembling, for example assembles through press.Each pore among the figure is represented the junction 10 of the upper and lower lamellar body of body 1.
The raw MAT'L of body 1 as shown in the figure is St12Q1, and thickness 2.0mm, tensile strength are 370～430Mpa; Yield strength is 245～300Mpa; The material stretch ratio is >=28%, and this material overall performance and chassis part common used material are similar, therefore has cooresponding representativeness.
If junction 10 is spot welding, automobile Control arm shown in Figure 1 is totally 30 solder joints, and road preface man-hour is 90 seconds, is 90 seconds during the Welder of this part, this shows, and is time-consuming longer.Simultaneously, because main dependence spot welding connects, the intensity of solder joint and reliability are the main guarantees of properties of product, and therefore, it is particularly important that online detection seems.In the process control of this part, the control device of solder joint is the power of the chiseling test and the incision test of per tour initial workpiece, simultaneously, monitors the main means of welding parameter as process control during the course.Because the before said power of chiseling test and incision test are destructive test, are difficult to high frequency time ground and detect, and therefore, also are difficult to realize online detection.
Therefore, among the embodiment of the utility model, junction shown in Figure 1 10 is improved to no rivet connects; Its connection speed is fast, and point of connection intensity is high, and method of inspection is for detecting the degree of depth of riveted joint place; The degree of depth is in scope, i.e. expression riveted joint point of connection is qualified, and this method is simple; Can realize online detection, guarantee the intensity of riveted joint.
