Abstract
A system for measuring the load carried by a vehicle of the type employing a leaf spring suspension. In a leaf spring suspension an elongated spring is supported between a pair of spaced apart hangers on each side of the vehicle. The hangers are then secured to the vehicle frame. An axle extends transversely beneath the vehicle and is clamped to the center of the springs. The measuring system includes four spaced apart strain gauges mounted on the upper surface of the spring beneath the axle clamp equidistant from the center of the spring. The strain gauges are connected to each other in a bridge configuration, and they measure the strain of the springs responsive to vehicle loading.
