HWH Active Air

[cmillsap]

David,

My previous 2000 LXi was equipped with probably HWH’s precursor to the active air system. The bus could be leveled with the hyd jacks or by the air springs. Although it was not able to actively keep the bus level while moving; it would allow the driver to raise or lower the front or rear air springs to clear objects while moving. I don't remember if side to side lowering or raising was possible. I believe it only worked at speeds below 15 mph. I used it many times to lower the front and raise the rear of the bus to keep the rear of the bus from dragging on the pavement during the transition from the street to the inclined driveway.

Obviously, the bag inflation on the rear was limited to the height above the ride height but the front would drop a good three inches. I presume the rear bags would also deflate to the bump stops also although I never tried that as I always parked the bus forward in the garage. I’d guess that HWH engineers are using that system as a base for the new “Active Air” system
