Abstract
A novel type of customizing kit for a vehicle air suspension system, comprising an additional air spring volume with a connecting line which can be connected to a vehicle main air spring volume, and with a switching device for selective connection or disconnection of the additional air spring volume. The switching device is arranged in the area of the connecting line and is designed such that when it is in an open position, it releases the cross section of the connecting line virtually completely for flow to pass through in both directions and when it is in a closed position, reduces the cross section to a specific residual opening cross section, such that this results in effective closure of the connecting line by use of a Helmholtz effect in a specific region of an excitation frequency of the oscillating air volume.
