1. Materials. The control arm ball head is made of all aluminum, and the front ball head is made of carbon steel. 2.In terms of usefulness. The control arm ball head is used for wheel steering motion, while the front ball head is used to make the car suspension and balance rod force transfer.

1. pneumatic device simple structure, light, simple installation and maintenance; 2. the working medium (the determining substance) is inexhaustible air, air itself does not cost money; 3. The adjustment of output force and working speed is very easy; 4. The reliability is not too high, and the use time is greatly influenced by the cleanliness of the air source and the frequency of use; 5. the use of air compressibility, can store energy, to achieve centralized gas supply; 6. full pneumatic control (control) with fire, explosion-proof, moisture-proof ability and other characteristics.

Suspension Bushing Light weight, reduce the impact of the body, and improve the ground adhesion of the wheel; Soft spring with small stiffness can be used to improve the comfort of the car; It can reduce the position of the engine and the center of gravity of the vehicle, thus improving the driving stability of the vehicle; The left and right wheels beat alone, irrelevant, can reduce the tilt and vibration of the body. However, the independent suspension system has the disadvantages of complex structure, high cost and inconvenient maintenance.

1. in the resistance of large torque driving, there will be the phenomenon of the car, reverse will also appear the car, must increase the throttle can be solved; 2. start or open the air conditioning refrigeration engine jitter is very large, the steering wheel vibration is obvious at high speed, and the acceleration and brake pedal are also seismic; 3. When accelerating in second or third gear, you can often hear the sound of rubber friction; 4. When the above problems are found in the foot glue of the engine, it can be determined that the foot glue has been damaged, please replace it in time. The engine is not effective shock absorption and support will damage some parts, thus affecting the performance of the engine, not only running jitter but also the engine fixed unstable shaking phenomenon.
