Specific Work Process: Achieving Functions in Coordination with System Components
The air reservoir cannot work independently. It needs to cooperate with the air pump, ECU (Electronic Control Unit), sensors, etc. The complete work process is divided into 3 steps:
Signal triggering: The vehicle height sensor continuously monitors the vehicle posture (such as height, tilt), or the driver selects the driving mode (such as "off-road" "sport") through the central control, and transmits the demand signal to the ECU.
Air pressure regulation: The ECU, based on the signal instructions, controls the air pump to inflate the air reservoir (when it needs to increase / become harder), or controls the exhaust valve to release the air in the air reservoir (when it needs to decrease / become softer).
State stability: When the air pressure in the air reservoir reaches the set value by the ECU (corresponding to the target height or stiffness), the sensor sends a feedback signal, and the ECU stops inflating or deflating, and the air reservoir maintains the current state to maintain vehicle stability.
Main Functions and Roles
Economical and practical: No need to replace the entire air tank, reducing maintenance costs.
Recovery performance: Replace aged rubber or seals to restore air tightness and shock absorption effect.
Easy installation: The structure matches the original size and maintenance is convenient.
Extended service life: Regular replacement of vulnerable parts can extend the overall service life of the air tank.
Strong adaptability: Widely applicable to the aftermarket air tanks of mainstream models such as Mercedes-Benz, BMW, Audi and Land Rover.
