Pneumatic shock
Theory
• Air Pressure Regulation:Air suspension systems use air pressure
to adjust the height and firmness of the vehicle's suspension.By
increasing or decreasing the air pressure,the suspension can be
raised or lowered.
• Airbags or Air Struts:These are the primary components that
replace traditional coil springs or leaf springs.They contain air
and are designed to provide a smooth ride by absorbing road shocks.
• Compressor and Pump:The compressor is responsible for pumping air
into the airbags or air struts to increase the pressure and raise
the vehicle.The pump is used to release air,lowering the vehicle.
• Control Unit:This is the brain of the system,which receives input
from various sensors and adjusts the air pressure accordingly to
maintain the desired ride height and damping characteristics.
• Sensors:These include height sensors,speed sensors,and sometimes
accelerometers,which provide real-time data about the vehicle's
position,speed,and movement to the control unit.
• Damping Control:The system can also control the damping
force,which is the resistance to the vehicle's body roll and
pitch.This is achieved by adjusting the flow of air in and out of
the airbags or struts.
• Load Leveling:Air suspension systems can automatically adjust to
maintain a constant ride height even when the vehicle's load
changes,ensuring stability and comfort.
• Adaptive Ride Height:Some systems can adjust the ride height
based on the driving conditions,such as lowering the vehicle at
high speeds for better aerodynamics or raising it off-road for
better ground clearance.
• Leak Detection:The system is designed to detect any leaks in the
airbags or air lines,which could affect the performance and safety
of the suspension.
• Energy Efficiency:Air suspension systems are often more
energy-efficient than traditional hydraulic systems because they
use air,which is a more readily available and less energy-intensive
medium.
• Noise Reduction:By providing a more compliant ride,air suspension
systems can reduce road noise and vibrations,leading to a quieter
and more comfortable cabin environment.
These principles work together to provide a suspension system that
is adjustable,comfortable,and capable of adapting to various
driving conditions.
