The air suspension is an element which replaces the coil spring of steel for a few springs that work with compressed air. Its main objective is to improve the safety and comfort thanks to a degree of cushioning is different that allows it to adapt to the irregularities of the terrain, minimizing the negative impact in the occupants of the vehicle, according to Loctite, and advance from Infotaller.
In the case of adaptive systems, those managed and automatically adjust the suspension to prevent rocking of the body and achieve maximum stability. In addition, this suspension can be applied on the rear axle or on all four wheels. But, what are main components ? Among them, are the sensors (measuring acceleration, the position of the chassis or the level of the axles), the electronic control unit (ECU) (commands the suspension system in accordance with the received signals) and the compressor filter dehydrator (compresses the air to increase the pressure of work and to ensure the constant flow of compressed air).
Also outstanding are the bellows, spring or air spring (replaces typical steel spring, and has a more soft), shocks specific to absorb vibrations, regulators of height and power group air, that cools the system. The post also indicates that this device has a valve block, electro-pneumatic pressure and a pressure accumulator for storing air to be used little by little.
so referred operation , the professionals of Loctite explain that the sensors send to ECU the measurements made in order to fit the shock absorbers. In the event that there is load and/or the height of the body decreases with respect to the pavement, the air spring bellows is compressed and the suspension becomes more rigid, so that the ECU commands the compressor that drives air and open the solenoid valve block pneumatic and retrieve the height of the body.
If there is no load on the vehicle and/or the distance of the body relative to the ground increases, the air spring bellows expands and loses pressure, so that the suspension becomes too soft. Then, the ECU commands the opening of the solenoid valve in the block electro-pneumatic pressure for the compressed air to leave the spring, and reduce the height of the body.Updated Date: 26 September 2019, 10:01
