Bellow, air suspension - 20425 FEBI BILSTEIN

Air suspension - a set of mechanisms that allows you to increase the height of the vehicle's ground clearance.

This suspension has a number of advantages over conventional, spring or leaf suspension:

1. increase in ground clearance, damping of uneven surfaces, ease of parking in the city at the curb
2. stabilization when cornering at high speed
3. air suspension increases the vehicle's carrying capacity.

The functionality of the FEBI BILSTEIN brand Boot, air suspension

The first reason why the air springs are rolled up in the boot is that the air spring is not designed to work open. He swells more than necessary and starts rubbing against the levers. Along the way, this is accompanied by changes in the volume of the spring itself, which affects the operation of the suspension and other units, for example, levers and steering rack. They receive increased loads.

The construction of the ball joint

The limitation of the clamped boot affects the operation of the air springs, because they are designed by engineers to work with open-type pneumatic elements.
