ABSTRACT:
An air spring load monitoring system provides a vehicle operator with an on-board visual display of the load distribution imposed on each axle from front to rear of a truck and trailer, and displays differential loads imposed from side to side across each axle as a result of local overloading caused by unequal load distribution. Pneumatic transducers produce analog output signals proportional to the internal air pressure of each air spring as an accurate indicator of payload distribution. Load data is presented by load display groups in which visual display elements are positioned in spaced relation along a scale representative of a predetermined air spring load range. The visual display elements of each group are positioned in side by side relation for visual comparison to each other and to the scale. Each visual display element is representative of a predetermined load range increment. A signal conversion circuit drives a predetermined visual display element in each display group which corresponds with the load range increment containing the air spring load value represented by the analog output signal.
