Automatic transmission noise insulation
Sound insulation of an automatic transmission (automatic transmission) is a set of measures aimed at reducing noise, vibration and hum emanating from the automatic transmission while the car engine is running.
Sources of noise and vibration in automatic transmission:
*Hydraulic pump
* Hydraulic block
* Planetary gears
* Shafts
* Couplings
Measures for automatic transmission noise insulation:
* Installation of soundproofing materials: Soundproofing materials, such as felt mats or bitumen-polymer sheets, are installed on the automatic transmission housing and pan to absorb noise and vibration.
* Use of sponges and gaskets: Sponges and gaskets made of rubber or polyurethane are installed between automatic transmission components to dampen vibrations and prevent their transfer to other parts of the car.
* Automatic transmission pan modification: Installing an additional soundproofing layer on the automatic transmission pan can significantly reduce the noise created by vibration of the pan.
* Improved joint seals: Seals and gaskets between automatic transmission components must be in good condition to prevent leaks and prevent noise and vibration from escaping.
* Installing Additional Sound Insulators: Additional sound insulators, such as exhaust mufflers or torsional shock absorbers, can help reduce noise transmitted from the automatic transmission to the engine or other parts of the vehicle.
Advantages of automatic transmission sound insulation:
* Improved acoustic environment inside the car
* Reducing fatigue and discomfort of the driver and passengers
* Increasing the durability of automatic transmissions by preventing the effects of vibrations
Note: Automatic transmission noise insulation must be performed by a qualified specialist. The use of unsuitable materials or improper installation may result in damage to the automatic transmission or poor performance.
