Air Suspension Tank-to-Spring Control for Stable Axle Height
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The frequent use of compressors in air suspension systems shortens their service life, as they are often used to adjust vehicle height, leading to increased energy consumption and reduced comfort due to inconsistent axle heights.
Innovation Solution
A vehicle control method that utilizes pressure differences between air springs and storage tanks to adjust axle heights by controlling the connection or disconnection of air circuits, reducing the need for compressor usage and prolonging system life.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If compressors are frequently used to adjust vehicle height, then height adjustment capability is improved, but service life of air suspension system deteriorates
Solution Approach 1:
The air storage tank stores compressed air in advance, enabling the air springs to automatically adjust axle heights using stored air pressure without requiring frequent compressor operation. The system serves itself by utilizing the pre-stored energy in the air tank rather than continuously relying on the compressor.
Solution Approach 2:
The compressor operates in advance to compress and store air in the air storage tank before it is needed for height adjustment. This preliminary action allows the system to have ready-to-use compressed air available when height adjustment is required, reducing the need for frequent compressor activation.
2Ease of operation
If compressors are frequently used to adjust vehicle height, then height adjustment capability is improved, but energy consumption increases
Solution Approach 1:
The compressor operates in advance to compress and store air in the air storage tank before it is needed for height adjustment. This preliminary action allows the system to have ready-to-use compressed air available when height adjustment is required, reducing the need for frequent compressor activation and lowering overall energy consumption.
Solution Approach 2:
The air storage tank stores compressed air in advance, enabling the air springs to automatically adjust axle heights using stored air pressure without requiring frequent compressor operation. The system serves itself by utilizing the pre-stored energy in the air tank rather than continuously relying on the compressor.
3Adaptability or versatility
If axle heights are not stabilized, then height adjustment flexibility is improved, but riding comfort deteriorates
Solution Approach 1:
The control module continuously monitors the heights of the front and rear axles and automatically controls the air circuits to maintain stable axle heights. This feedback mechanism ensures that the system adjusts heights flexibly when needed while maintaining stability for comfort during normal operation.
Solution Approach 2:
The air storage tank provides stable air pressure to the air springs, enabling automatic stabilization of axle heights without frequent compressor intervention. The system self-regulates to maintain consistent height for comfort while preserving adjustment capability when required.
