Vehicle development is inconceivable without reliable load data. If this involves the dynamic measurement of forces and moments in the design of chassis, nothing is possible without wheel force sensors. But they have to measure ever higher loads. The test bench for truck measuring wheels developed by Fraunhofer LBF covers radial forces of up to 400 kilonewtons, lateral forces of up to 200 kilonewtons and tangential forces or drive and braking torques of up to 100 kilonewton meters.
"Wheel force sensors today cover much larger load ranges than in earlier years. With the newly developed test stand, wheel force sensors for heavy vehicles can now also be calibrated over the full measuring range at the Fraunhofer LBF. This saves time and money despite the higher forces," explains Johannes Käsgen, responsible for the development of the calibration test stand at the Fraunhofer LBF. The new test stand is suitable for wheel force sensors from various manufacturers. It can be flexibly adapted to different wheel geometries using adapters.
