Abstract: The present invention relates to a system for adjusting weight distribution throughout all axle groups of the truck and trailer. The trailer has at least one axle group mounted on a pair of rails attached to the frame of the trailer. These axle groups are locked in position on the rails by locking pins. The system for adjusting weight distribution according to the present invention measures the weight on every axle group on the truck and trailer. The measurement may be of weight directly by load cells etc. or indirectly, by taking measurements from the air suspension system to calculate weight. The measurements are delivered as an electrical signal to one or more microprocessors capable of receiving the electrical signals and calculating the optimum position of the axle group on the trailer. The position of the trailer axle groups relative to the rails is also determined and the position delivered to the microprocessor(s).

Abstract: The present invention relates to a system for automatically adjusting weight distribution throughout all axle groups of the truck and trailer. The trailer may have one or more axle groups mounted on a pair of rails attached to the frame of the trailer. The axle groups are locked in position on the rails by locking pins. The system for automatically adjusting weight distribution according to the present invention comprises means for measuring the weight on every axle group on the truck and trailer. The measurement may be of weight directly, where the means for measuring weight consists of load cells etc. or indirectly, where the means for measuring weight takes measurements from the air suspension system to calculate weight. The measurements are delivered as an electrical signal to one or more microprocessors capable of receiving said electrical signals and calculating the optimum position of the axle groups on said trailer.
