Air suspension systems are used for heavy payloads, varying payloads, when extra comfort is required (passenger transport) or when the ride height needs to be adjustable. The difference between semi air suspension and full air suspension is that semi air suspension is an additional suspension system, alongside or in the original suspension system, while full air suspension is or will be the basic suspension system. The difference between these systems:
Semi air suspension:
A semi air suspension system is installed additionally to the existing suspension system of vehicles. The purpose of semi air suspension is to provide additional support when carrying heavy or varying payloads. In doing so, comfort is improved and driving characteristics remain optimal, which also contributes to vehicle safety. The air spring bellows are fitted in the original coil springs, or on or next to the original leaf springs. They can be inflated manually or by using a compressor to adjust the vehicle's ride height. An additional advantage of semi air suspension is that the vehicle remains driveable in the event of a failure of the air suspension system.
For filling e/o operating, MAD offers:
- Basic: manual with fill valve(s)
- Comfort: manual via control panel and compressor
- Automatic: fully automatic height control. Using height sensors, the set ride height is automatically kept constant at all times. The height sensors are contactless, making automatic height control completely interference-free.
Full air suspension:
Full air suspension is a more advanced system that is or completely replaces the vehicle's original suspension system. This type of system is often used in passenger transport, ambulances and wheelchair transport. This is because it offers ultimate comfort for driver and passengers. You set the desired ride height once using the height sensor(s) and the system ensures that the vehicle remains at this ride height under all circumstances. Optionally, it is possible to operate the system manually (Dual Control) or add a kneel-down function (Low Entry Control). This allows the driver to manually control the ride height temporarily, making entry easier or adjusting the ground clearance.
In short, semi air suspension is an additional suspension system that provides additional support to a vehicle's existing suspension system, while full air suspension performs the suspension function completely independently. Choosing the right system depends on the vehicle's technical capabilities, the original suspension system and the end user's needs and budget.
