[0002] The lower control arm of a car is an important component in the vehicle suspension system. Its main function is to connect the wheels to the body of the car. It also bears the weight of the vehicle and various forces during driving. Therefore, the hardness required by the control arm is particularly important.

[0003] However, in the prior art, due to the bumps that occur during the driving of the vehicle, the control arm will often vibrate. The impact force generated by the long-term vibration is very likely to cause damage to the internal structure of the control arm, resulting in the control arm as a whole being unable to continue to be used, thereby reducing the life of the control arm. Therefore, it is necessary to propose a new type of control arm for vehicle suspension. Utility Model Content

[0006] Preferably, the inner surface wall of the wall body is provided with a plurality of reinforcing ribs, so as to utilize the structure of the reinforcing ribs to improve the hardness and life of the wall body.

[0007] Preferably, the outer walls of the wall body and the plurality of reinforcing ribs are coated with anti-corrosion paint, and the anti-corrosion properties of the anti-corrosion paint are utilized to prevent the wall body from being corroded.

[0008] Preferably, the inner surface walls of the two fixing sleeves and the inner surface walls of the mounting grooves are fixedly inserted with rubber rings, and the inner surface walls of the three rubber rings are fixedly inserted with metal rings, so that after the wall body is installed on the steering knuckle and the vehicle body, the shock absorption capacity can be improved by the rubber rings and the metal rings.

[0009] Preferably, the outer wall movable sleeve of the wall body is provided with an upper shell and a lower shell, and the upper shell and the lower shell are fixedly connected by bolts and nuts, so that the wall body can be protected by the upper shell and the lower shell to prevent sewage from splashing onto the wall body.

Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a control arm of a vehicle suspension, comprising: a wall body 1 and a vehicle body 5, a fixing sleeve 2 is welded to the outer wall of the wall body 1, a mounting groove 16 is opened on the outer wall of the wall body 1, two groups of fixing blocks 4 are welded to one side of the outer wall of the vehicle body 5, fixing components 3 are movably inserted into the inner walls of the outer walls of the two groups of fixing blocks 4, and the outer walls of the two fixing components 3 are movably inserted into the inner walls of the two fixing sleeves 2 respectively, a first mounting block 6 is welded to the top of the wall body 1, a second mounting block 7 is welded to one side of the outer wall of the vehicle body 5, a damper 8 is installed on one side of the outer wall of the first mounting block 6 by means of an earring, and one side of the outer wall of the damper 8 is connected to the second mounting block 7 by means of an earring, and a spring 9 is arranged on the outer wall of the damper 8.

[0022] The effect achieved by the entire embodiment 1 is that by arranging the damper 8 and the spring 9, the mounting groove 16 of the wall body 1 is connected to the steering knuckle on the vehicle, and the fixing sleeve 2 is connected to the fixing block 4 on the vehicle body 5. In this way, when the vehicle is running, once the vehicle is bumpy, the wall body 1 will rotate slightly according to the fixing block 4, thereby squeezing the damper 8 and the spring 9, and then the damper 8 and the spring 9 will offset a part of the impact force generated by the vibration of the wall body 1 according to their own elastic characteristics. In this way, when driving the same distance, the wall body 1 installed with the spring 9 and the damper 8 will suffer less damage than when not installed, thereby increasing the life of the wall body 1.

[0023] Embodiment 2, as Figure 1-Figure 4As shown, the inner surface wall of the wall body 1 is provided with a plurality of reinforcing ribs 10, the outer surfaces of the wall body 1 and the plurality of reinforcing ribs 10 are coated with anti-corrosion paint, the inner surfaces of the two fixing sleeves 2 and the inner surfaces of the mounting groove 16 are fixedly inserted with rubber rings 11, the inner surfaces of the three rubber rings 11 are fixedly inserted with metal rings 12, the outer surface wall of the wall body 1 is movably provided with an upper shell 13 and a lower shell 14, and the upper shell 13 and the lower shell 14 are fixedly connected by bolts and nuts, the outer surface wall of the wall body 1 is provided with a plurality of sealing gaskets 15, and the plurality of sealing gaskets 15 are movably inserted between the upper shell 13 and the lower shell 14.

[0024] The effect achieved by the entire embodiment 2 is that, by setting the reinforcing ribs 10, the stability of the wall body 1 can be improved, and the hardness of the wall body 1 is further improved.

[0025] The working principle of the whole device is as follows: the wall body 1 is connected to the steering knuckle on the vehicle by connecting the mounting groove 16 of the wall body 1, and then the fixing sleeve 2 is connected to the fixing block 4 on the vehicle body 5, and fixed by the fixing assembly 3, so that the wall body 1 can be installed on the vehicle body. During driving, if bumps occur, the rubber ring 11 and the metal ring 12 in the fixing sleeve 2 will be slightly tilted under the shock-absorbing effect, thereby reducing the angle between the wall body 1 and the vehicle body 5, and then the damper 8 and the spring 9 are squeezed, and then the elastic potential energy generated by the damper 8 and the spring 9 when being squeezed will buffer the impact force generated by the wall body 1 to a certain extent. At the same time, during driving, water will inevitably splash onto the wall body 1 from the bottom of the vehicle body, and at this time it will be sealed by the upper shell 13, the lower shell 14 and the sealing gasket 15 to prevent water from splashing onto the wall body 1 and causing corrosion to the wall body 1.
