Optimum transducer positioning for vehicle axel load measurement - two transducers mounted on axle and two on springs

摘要

A method of positioning force transducers on the load bearing axles of vehicles so that their loads can be measured accurately, is presented. Basically, two transducers (8,9) are mounted on each side of the vehicle load bearing axle (1), one transducer (9) being next to the wheels - which are typically of double tyre type, and the other being directly under the load bearing springs (2), but on the opposite side of the axle. Four transducers in all are thus used. The transducers next the wheels may be above (9) or below (9') the axle. These combinations may then be used in circuits to give reliable load measurements as required.
