The lifespan of air suspension is 3-5 years. If the road conditions are good and the car is in normal use, it can be replaced once every 5 years. If the car is frequently parked and not in use and the road conditions are poor, it can be replaced once every 3 years. Air suspension is based on different road conditions and signals from distance sensors. The driving computer will detect changes in vehicle height and control the air compressor and exhaust valve to automatically compress or extend the spring, thereby reducing or raising the ground clearance of the chassis to increase the stability of high-speed vehicles or the passability of complex road conditions.
Advantages of installing air suspension:
1. Lightweight
One of the biggest advantages of air suspension is its light weight, which is much lighter than traditional steel plate spring suspension. This is also an important reason why ordinary users pay attention to air suspension. Under the current weight based charging, the lightweight advantage of air suspension is obvious.
2. Adjustable
The ability to lift and lower is reflected in two aspects. Firstly, through air suspension, the axle can be lifted, which is beneficial for reducing tire wear and saving fuel, especially suitable for working conditions with unilateral emptying. Secondly, air suspension can reduce the height of the vehicle's cargo platform to a certain extent, making it easier to load and unload goods.
3. Smooth driving
Compared to lightweight, it is worth noting that vehicles with air suspension have smoother driving. The elastic coefficient of the air spring, which is the softness and hardness of the spring, can be automatically adjusted according to the needs. When the vehicle is driving at high speeds, the air spring becomes harder to improve the stability of the vehicle. When encountering poor road conditions, the air spring becomes softer to improve the comfort of the vehicle.
Disadvantages of installing air suspension:
1. High price
The imported air suspension system now costs as little as 70-80000 yuan and as much as 100000 yuan. Domestic air suspension is relatively cheaper, but its quality and reliability need to be further improved.
2. Strict requirements for cargo tonnage
Air suspension vehicles have strict requirements for cargo tonnage. When loading, be sure not to overload. Overloading can cause significant damage to the air suspension and reduce its service life.
