Abstract

The utility model discloses an automobile control arm which comprises a bracket, a suspension ball joint and a bush which are processed independently. The bracket is of an L-shaped bracket which is provided with three top ends; the suspension ball joint is arranged at the first end of the bracket; the bush comprises a first bush and a second bush; the first bush and the second bush are respectively arranged at the second end and third end of the bracket; the axial plane of the first bush and the second bush and the bracket are in the same plane. Each component of the automobile control arm is processed independently and then is assembled into the automobile control arm, so the structure is simplified, the number of forging dies and stamping dies of blanks is reduced, the manufacturing difficulty is lowered, the rejection rate is reduced, and the blank cost is lowered. In addition, the integrated processing is changed into assembled processing so as to reduce the processing difficulty, improve the processing efficiency, be applicable to bulk production and contribute to promotion.

Description

The automobile Control arm

Technical field

The utility model relates to a kind of Control arm, is specifically related to a kind of automobile Control arm that can improve work efficiency and be applicable to production in enormous quantities.

Background technology

The automobile Control arm is the important safety part in the car chassis system, is used to connect braking and suspension system, transmitted load, assurance wheel alignment parameter.At present, the automobile Control arm that uses on the car is generally sheet metal component or forging, all by after press-fiting lining on the Control arm, hanging bulb, connects back trailing arm and upper suspension arm.The automobile Control arm of prior art comprises and hangs bulb, the position, hole on support and two and Control arm bonded assembly lining as shown in Figure 1.This automobile Control arm is owing to will take into account the overall plan of suspension system and the positional parameter of wheel when design, there is space angle between the bobbin of the suspension bulb on Control arm the place ahead and two linings at rear, cause the product structure complexity, both increase the metalworking difficulty and strengthened, increased the quantity of blanked part mould again.

The utility model content

Goal of the invention: in order to overcome the deficiencies in the prior art, the utility model provides a kind of designs simplification, the independent respectively processing of each assembly, the automobile Control arm that assembles then.

Technical scheme: to achieve these goals, a kind of automobile Control arm of the present utility model, comprise the support, suspension bulb and the lining that independently process respectively, described support is " L " shape support with three tops, hangs first end that bulb is installed in support; Described lining comprises first lining and second lining, and first lining and second lining are separately positioned on second end and the 3rd end of support; The axis plane of first lining and second lining and support are at grade.

To hang bulb in order better installing, to be provided with mounting hole at support first end, it is rack-mount with cooperating of mounting hole by screw to hang bulb.

Hang the more firm of bulb installation in order to make, described mounting hole has three, and three triangular in shape arranging of mounting hole connect the suspension bulbs with three screws.

In order to alleviate the weight of support, described internal stent can be designed to hollow structure, can guarantee that promptly support can work normally, reach the purpose that alleviates quality weight again.

First lining and second lining are installed in support second end and the 3rd end by axle sleeve respectively, and the axis plane of first lining and second lining and support are at grade.

Beneficial effect: compared with prior art, a kind of automobile Control arm of the present utility model has the following advantages:

1, owing to designs simplification, total quality can reduce 30%-40%;

2, because designs simplification reduces the forge mould of blank and stamping die quantity, can reduce manufacture difficulty, reject rate be reduced, thereby reduce the blank cost;

3, because there is not space angle in designs simplification, finished surface reduces, and makes the metal working frock clamp simple in structure, and quantity reduces, and reduces the requirement to Fabricating machinery, can reduce processing step, and the metalworking cost is reduced;

4, owing to change integral type processing into assembly type processing, can reduce difficulty of processing, improve work efficiency, be applicable to production in enormous quantities, help promoting the use of.

Description of drawings

Fig. 1 is the structural representation of existing automobile Control arm;

Fig. 2 is a structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explanation.

As shown in Figure 2, a kind of automobile Control arm of the present utility model comprises the support 4, suspension bulb 1 and the lining that independently process respectively, and support 4 hangs first end that bulb 1 is installed in support 4 for having " L " shape support on three tops; Lining comprises that first lining 5 and second lining, 6, the first linings 5 are installed in second end of support 4, and second lining 6 is installed in the 3rd end of support 4; The axis plane of first lining 5 and second lining 6 and support 4 are at grade.

In the present embodiment, be provided with mounting hole at support 4 first ends, hanging bulb 1 was installed on the support 4 by screw 2 and cooperating of mounting hole, the quantity of mounting hole is three, three triangular in shape arranging of mounting hole, connect the suspension bulb with three screws 2, can well fix and hang bulb 1, do not allow suspension bulb 1 on support 4, rock.In addition, support 4 can be designed to hollow structure inside, can guarantee that promptly support 4 can work normally, can reach the purpose of expendable weight again.Support 4 is provided with several auxiliary holes 3.

A kind of automobile Control arm of the present utility model can process support 4 respectively in the processing and manufacturing process, hang bulb 1 and two linings, then each assembly is assembled and get final product reduction difficulty of processing, raising work efficiency, be applicable to production in enormous quantities, help promoting the use of.

The above only is a preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
