Description

Automobile control arm

Technical field

The utility model relates to a kind of automobile suspension system components, and in particular to a kind of automobile control arm.

Background technique

Automobile control arm is applied in the suspension of automobile chassis, and the automobile of three swing arms of band of the prior art controls Arm, using overall structure, wherein the swing arm of an installation back bush component with a distance from control arm mounting hole farther out, it is long Spend it is also longer, so casting structure can be complex, and be easy to produce fracture in loading process, product using it is safe can By property, there are certain hidden danger.In addition, the sensor being installed on automobile control arm also can be larger by vibration influence, it is easy to appear event Barrier.

Summary of the invention

In view of the deficiencies in the prior art, the technical problems to be solved in the utility model be to provide a kind of structure it is simple, Improve the safety and reliability of product, and the automobile control arm with flexible installing pedestal.

The utility model adopts the following technical scheme that complete:

Automobile control arm, including swing arm, swing arm have central pedestal and are connected to central pedestal and to different directions Control arm mounting hole is arranged in the first, second, third swing arm extended, the intermediate of central pedestal, and the end of the first swing arm is equipped with ball Head assembly, the end of the second swing arm are equipped with front lining component, and the end of third swing arm is equipped with back bush component, it is characterised in that: First, second swing arm and central pedestal use conjoined structure, and third swing arm and central pedestal use separate structure, third swing arm with Bolt connecting mode is fixedly linked with central pedestal.

Third swing arm is being equipped with steel wire close to end positions, and steel wire one end is fixedly linked with third swing arm, and the other end is in Centre pedestal is fixedly linked, and central pedestal is equipped with connecting stud in the top position close to third swing arm, and steel wire is wound around connection spiral shell It is locked after on column by locking nut.

First swing arm is equipped with damping rubber pad in the lower position of bulb component.

The automobile control arm of above-mentioned technical proposal, the longer third swing arm of length and central pedestal and the first, second swing arm Using separate structure, third swing arm is fixedly linked with bolt connecting mode and central pedestal, and so, casting structure can be more Simply, the material that third swing arm can also be high using intensity, is allowed to be not easy to produce fracture in loading process, even if just in case going out Existing third swing arm crack conditions, as the connection of steel wire and central pedestal is designed without falling off automobile control arm Main body improves the safety and reliability of product；In addition, the design of a plurality of steel wire makes it possible to the flexible installing as sensor Pedestal reduces it by vibration influence, improves service life.Finally, the setting of damping rubber pad can play effectively subtracting for swing arm Shake effect.

Detailed description of the invention

The utility model has following attached drawing:

Fig. 1 is the structural schematic diagram of the utility model.

Specific embodiment

As shown, the automobile control arm of the utility model, including swing arm, swing arm have central pedestal 1 and connection In central pedestal 1 and to the first swing arm 3 of different directions extension, the second swing arm 4, third swing arm 5, the centre of central pedestal 1 is set Control arm mounting hole 2 is set, the end of the first swing arm 3 is equipped with bulb component 6, and the first swing arm 3 is set in the lower position of bulb component There is damping rubber pad 9, the end of the second swing arm 4 is equipped with front lining component 7, and the end of third swing arm 5 is equipped with back bush component 8, the One swing arm 3, the second swing arm 4 and central pedestal 1 use conjoined structure, and third swing arm 5 and central pedestal 1 use separate structure, the Three swing arms 5 are fixedly linked with 15 connection type of bolt and central pedestal 1.Third swing arm 5 is being equipped with two bar steels close to end positions One end of line 13,14, two steel wires 13,14 is fixedly linked by screw-driving and third swing arm 5, the other end and central pedestal 1 It is fixedly linked, central pedestal 1 is equipped with connecting stud 10 in the top position close to third swing arm 5, and steel wire 13,14 is wound around connection It is locked after on stud 10 by locking nut 11, flexibility of the clamping plate 12 as sensor is fixedly installed on two steel wires 13,14 Installation pedestal.
