What are the main faults in the transmission shaft?

The main cause of engine noise!
1, the rubber pad body: cab and frame of the car is connected to the ji'ao automobile key parts caused by noise, a rubber pad factory loading with GIO (glial) too hard, fixed bolts, no gap between the body and the crossbeam, as welded together, vehicles in the road, because of the power requirements the engine output changes in an instant, but also to different road vehicles in the process brings a very demanding technology, mechanical components in their operation, the vibration noise itself many unspeakable. Because the connecting pad is not standard, it can not effectively absorb and release. On the contrary, it plays the role of collecting and transmitting. The sound produced by different parts of the cab resonates with the rubber pad and resonates inside the cab. Spring plate after the rubber sleeve is made of a nylon material factory GIO, its texture is too hard, no vibration, the vehicle has a squeaky voice in the running, replacement of the different materials of the steel plate spring rubber sleeve, this phenomenon disappeared.
2, the transmission gear box machine: the difference of the height of the bracket pad so that the transmission shaft, the level of bridge bearing fixed frame surface is not balanced, the drive shaft to rotate for elliptical rotation, which generate unnecessary vibration, the vehicle noise sources increased. We aimed at this phenomenon, the transmission machine claw bracket processing welding, raise 3 centimeters, let the engine left and right machine claw pad and transmission machine claw pad force balanced. The incorrect angle of the drive shaft and the bridge bearing is changed, and a flexible rubber claw pad is replaced to make it absorb and release the vibration force produced by the engine when it is working.
3 transmission system: the transmission shaft ji'ao automobile defective vehicle transmission when driving shaft shaking phenomenon of irregular, exacerbated by the noise. After the replacement of parts of different manufacturers, the phenomenon is eliminated, thereby reducing the noise generated by an important link, the replacement of different types of transmission shaft, the failure to disappear. Specific entities take photos as an example.
4, air filter: loading use this type of air filter assembly in the engine idling, the engine of the air demand is relatively balanced, then there is no exception, but the load change in the engine, from low speed to high speed increases quickly, the engine demand for air quantity instantly becomes larger, because the air filter assembly small air inlet air is short, strong suction inlet flow through quickly into the air cleaner filter chamber, the internal space is too small, not all moments through the air filter air, air inlet echoed oscillation. If the inner space of the air filter housing is increased, the intake duct is lengthened and properly bent, and the silencing function can be better. After changing different types of air cleaner assembly, enter the engine
