Abstract
An on-board system for measuring vehicle loads on dual axles with a suspension system having a front hanger, a rear hanger, an equalizer and an equalizer hanger. Attached to the equalizer, in one embodiment, are a plurality of strain gauges, arranged in two cut-out portions. The strain gauges are positioned so that the measured strain corresponds to the force of the vertical load on the equalizer. The output of the strain gauges is then applied to a conventional bridge circuit and from there to a conventional electronic circuit to provide a display which indicates the weight of the load on the dual wheels.
