<p>System for measuring the load acting on a vehicle axle, the vehicle comprising a frame (F) and said axle (A) being connected to the frame by means of a suspension system, the system comprising extension/retraction means (P) fixed indifferently either to the frame (F) in correspondence of the axle (A) or to the vehicle axle (A), in order to interpose between the frame (F) and the axle (A) only when they are in extended position, means for measuring a load or a load variation (FLM) on the axle (A) comprising a sensor (S) associated to the extension/retraction means (P) adapted to produce an electric signal proportional to a compression/lightening of the extension/retraction means (P) and first processing means (VCU) adapted to control the extension/retraction means (P) in order to move to an extended condition when the vehicle speed is lower than a predetermined threshold and to a retracted condition at least when the speed of the vehicle exceeds said threshold and second processing means (VCU) adapted to calculate a value of weight weighing on the axle (A) on the basis of the electric signal.</p> |
