Abstract
Apparatus and process for shifting vehicle loads between the axles of multi-axle vehicles. The apparatus includes means for automatically restoring pneumatic pressure to the suspension system of an axle when the speed of the vehicle exceeds a predetermined speed. The apparatus also includes means for automatically exhausting the pneumatic pressure if the speed of the vehicle falls below the predetermined speed within a predetermined time from actuating the device. The process includes the steps of automatically restoring pressure to the pneumatic suspension system of a dead axle when a predetermined speed has been exceeded, and again exhausting the pressure if a fall in vehicle speed below the predetermined speed occurs within a specified time. An override in both the apparatus and method prevents exhaustion of the pneumatic pressure after a predetermined time from first exhausting the pressure.
