Nowadays, many luxury cars on the market will use air suspension in the choice of suspension system, which can bring consumers a more comfortable driving experience.
So, what are the advantages and disadvantages of the air suspension system? Can the air suspension leak be repaired? Let's take a look together below.
Introduction to Air Suspension
Air suspension refers to the addition of an air bag outside the coil spring or the establishment of an air chamber inside. By adjusting the damping airbag or the gas in the air chamber, it plays a role in changing the damping state and stabilizing the body level.
In general, the air suspension system is composed of a control computer, shock absorber, air circuit, air distributor, and air compressor.
When the air suspension is active, the air compressor works and delivers an endless supply of air into the air pipe. According to the data fed back by the vehicle height sensor, the computer controls the distributor to distribute the gas to the shock absorption of the four wheels to make changes.
At the same time, there is an exhaust valve in the shock absorber, which can remove the air inside when it is not needed. According to the position of the airbag, there are generally two common air suspensions. One is to install the airbag alone on the outside to exist independently, while the other is to install the airbag inside the shock absorber and the shock absorber is integrated.
Advantages and disadvantages of air suspension
Advantages: Air suspension is generally soft and hard adjustable. Its working principle is that the sensor transmits the collected signal to the control unit. The control unit calculates and sends instructions to adjust the air spring hardness and shock absorber damping. And to achieve the most ideal state of elasticity.
There are many air suspensions, and the traditional chassis lifting technology is integrated into them. When driving at high speed, the height of the vehicle will automatically decrease to achieve the purpose of reducing wind resistance and reducing fuel consumption, and to enhance the stability of the vehicle during driving.
Nowadays, luxury cars are gradually adopting air suspension, and only one reason is to improve the comfort of passengers, and air suspension is used as a highlight to reflect the high quality of the car and promote products more convincingly.
Disadvantages: After talking about the advantages, the air suspension also has certain disadvantages. One of them is the high cost of purchase or optional equipment, which usually costs 50,000 to 100,000 yuan. There are many luxury models that air suspension is just an option. There are very few standard air suspensions in the whole series, except for some top models. In addition, the air suspension is perfect during use, but once a malfunction occurs, the maintenance cost is high.
Can the air suspension leak be repaired?
Air Suspension Air Suspension System (AIRMATIC) is an advanced product popular in the automotive industry in developed countries today. In developed countries, 100% of medium-sized and above passenger cars use air suspension systems, and more than 40% of trucks, trailers and tractors use air suspension systems. Its biggest advantage is: not only can improve the ride comfort of the occupants, but also can protect the road.
The air suspension system has at least four air damping and air pressure pipelines, electronic control valves, and a control module. Now it can be repaired technically, but the quality of the repair is difficult to say, and the cost is extremely high (for 4S shops, it is extremely large Some brands are not allowed to repair), it is recommended to replace parts under non-extreme conditions to ensure the quality of repair.
Can the air suspension leak?
Theoretically, it is not possible to continue driving (partially worn tires, uneven force on the wheels, strong suspension), and a trailer is recommended under non-extreme conditions.
In addition, if there is a leak, repair it as soon as possible, otherwise the compressor will continue to work due to leaks, which will cause damage or reduce the service life. After parking, observe the four corners of the front and rear of the vehicle to see which is too low and which is the leak. The front wheel is to replace the shock absorber assembly, and the rear wheel can be replaced with the air bag.
