Wheel force transducer RoaDyn S260 for rolling resistance measurement of C2 and C3 tires, 60 kN / 9289A113

The two-axis wheel force transducer RoaDyn S260 is the ideal instrument to measure rolling resistance on commercial vehicle tire test machines. It measures the longitudinal and vertical forces Fx and Fz, acting at the tire contact area respectively tire footprint. The measurement of rolling resistance basically takes place by using the force method, described in corresponding ISO and SAE regulations. In that case the reaction force is measured as close as possible at the tire contact area (footprint). The force method increases measuring accuracy and reduces parasitic losses compared with the common approach based on “torque, deceleration or power method”! Furthermore the force method allows to check two tires simultaneously, allowing for a significant increase in efficiency compared to other methods.
