The single-chip type control arm is characterized in that one end of the control arm body is connected with a casing pipe which is used for being connected with an auxiliary frame, a flange board is arranged between the casing pipe and the control arm body, the end portion of the control arm body is welded on one lateral side of the flange board, the casing pipe is welded on the other lateral side of the flange board, and the casing pipe extends in the longitudinal direction of the control arm body.
Description
Technical field
The utility model relates to the Control arm for automotive suspension.
Background technology
L type Control arm is used for the suspension of mcpherson type more, notification number comprising for the disclosed Control arm of utility model patent of " CN101348061 ": rubber bush behind rubber bush and the Control arm before the bolt that Control arm body, the ball end assembly, three that are used for connecting steering swivel link together ball end assembly and Control arm body, the Control arm, the Control arm body adopts the individual layer steel plate punch forming of SAPH440 thickness 3.0mm, and rubber bush all adopts interference fit to utilize compression machine to be pressed into the Control arm body before and after the Control arm.Because the Control arm body adopts the single-skin panel punch forming.With respect to the Control arm of last lower body welding, weight can alleviate greatly, has reduced non-suspended mass, can improve vehicle handling and stability and travelling comfort.The weakest place of this type of Control arm occurs stress here easily and concentrates at steel stamping part and the steel pipe weld that is used for installing rubber bush.
The utility model content
The purpose of this utility model is to provide a kind of one chip Control arm, has improved structure.
For realizing the one chip Control arm of described purpose, for L shaped, the Control arm body is the monolithic blanked part, it is characterized in that, one end of Control arm body is connected with the sleeve pipe for the auxiliary connection vehicle frame, between sleeve pipe and the Control arm body flanged plate is arranged, the end of the side welding Control arm body of flanged plate, the another side welded casing, this sleeve pipe is at the longitudinal extension of Control arm body.
Described one chip Control arm, wherein, this sleeve pipe passes this end welding of this flanged plate and Control arm body.
Described one chip Control arm, wherein, the other end of Control arm body is welded with for the steel pipe that rubber bush is installed, and the bight of Control arm body is welded with for the steel pipe that bulb is installed.
Described one chip Control arm, wherein, the edge of Control arm body is upper overturning.
Described one chip Control arm, wherein, there is reinforced rib the centre of Control arm body along the length direction punching press of Control arm body.
Described one chip Control arm wherein, stamps out lightening hole on the reinforced rib, the edge of this lightening hole is the flange shape.
The utility model is all having improvement aspect the traveling comfort of structural strength, fatigue life, increase automobile, and these advantages will be described in detail in embodiment described later.
Description of drawings
Fig. 1 is the block diagram of one chip Control arm among the utility model embodiment.
The specific embodiment
As shown in Figure 1, the one chip Control arm for L shaped, comprises Control arm body 1, two steel pipes 2,5 and sleeve pipe 3.Control arm body 1 is the monolithic blanked part, the one end is connected with the sleeve pipe 3 for the auxiliary connection vehicle frame, between sleeve pipe 3 and the Control arm body 1 flanged plate 4 is arranged, the end of the one side welding Control arm body 1 of flanged plate 4, another side welded casing 3, sleeve pipe 3 are roughly at the longitudinal extension of Control arm body 1.The right-hand member that sleeve pipe 3 can also pass flanged plate 4 and Control arm body 1 directly welds.
The left end welded steel pipe 2 of Control arm body 1, steel pipe 2 is used for installing bulb.The bight welded steel pipe 5 of Control arm body 1, steel pipe 5 is used for press-fiting rubber bush.
The edge of Control arm body 1 is upper overturning 10, along whole length direction punching press reinforced rib 11 is arranged in the centre of Control arm body 1, and three lightening holes 12 are arranged on the reinforced rib 11, and the edge of lightening hole 12 is the flange shape.
What the preceding attachment point that Control arm as shown in the figure is connected with subframe adopted is at Control arm body 1 mode that forging is sleeve pipe 3 to be installed, existing Control arm is the mounting hole that preceding attachment point place directly stamps out mounting bush, the rotary freedom of the Y-direction of attachment point before and after this mounting means has retrained, and the connection mode of Control arm has as shown in the figure discharged the Y-direction rotary freedom of front and back attachment points fully, being conducive to wheel can not be bent by the retentive control arm when beating bearing Z-direction, thereby keep the stable of subframe, increased the traveling comfort of automobile.
Control arm has as shown in the figure increased a new flanged plate, is used for sleeve pipe 3 is connected with Control arm body 1, has reduced the influence of the weld strength deficiency when sleeve pipe 3 is connected with Control arm body 1.Flanged plate 4 has increased the fatigue life of Control arm body 1 and sleeve pipe 3 junctions greatly.
Because what Control arm adopted is the design of upper overturning 10, and the employing of existing monolithic Control arm is the design of downward flange.The design of adopting to upper overturning can reduce the height of principal plane of the integral body of Control arm, has avoided the interference situation of Control arm flange and tire to a certain extent.Herein upper and lower is the orientation of relative Control arm when being installed on car chassis.
Embodiment as shown in the figure adopts the Control arm of monolithic design to reduce welding sequence greatly, has reduced the risk of the Control arm inefficacy that causes because of problems of welded quality, has also reduced the quality of whole Control arm, has reached the weight-saving target.
Simultaneously, the design of the upper overturning of previous embodiment has increased rigidity and the intensity of whole Control arm, makes thinner lighter that Control arm can design under situation about meeting design requirement.
And, stamping out three lightening holes 12 on the reinforced rib 11, lightening hole 12 adopts the design of flange, has reduced the stress concentration phenomenon that produces because of perforate, has also reached the purpose of loss of weight.
