DEVICE FOR MEASURING THE NET WEIGHT OF THE LOAD AND OF THE AXLE LOAD OF A TRUCK

摘要

The measuring device of the useful load and of the load on the axles of a truck comprises load cells mounted on a truck frame. A plate transmits the weight of the tipper and the one of the useful load to the load cells. The device comprises three load cells forming a system having three bearing points. The axis of the single front load cell is perpendicular to the common axis of the rear pair of load cells. This arrangement and the fact that each load cell is mounted on a knee-joint permits to eliminate the parasitic constraints of flexion and torsion on the load cells so that the load cells are submitted only to the constraints resulting from the weight of the tipper and the one of the useful load which improves considerably the precision of the measurement.
