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). The microprocessor(s) is programmed to calculate the
weight on each axle group and determine any change in position of the trailer axle
group(s) on the rails to optimize the weight distribution. The information is presented
to the driver on a display located in the cab of the truck. The system further
includes apparatus to lock and unlock the locking pins that lock the trailer axle
group(s) in position on the rails. The system also includes a communication interface
between the truck and the trailer.
