During the development of motor vehicles, 6- component wheel force transducers (WFT) are used, to determine and record the forces and torques at the wheels during test drives – each 3 forces (Fx, Fy, Fz) and 3 torques (Mx, My, Mz). The measurement results generate the fundament for simulation calculation and input parameter for test rig drives. CAEMAX presents with the WFT-CX for the first time a generation of completely new wheel force trans- ducers, that are not only completely waterproof and further more provides a higher thermal and mecha- nic load to perform even extreme off road tests (SUV) at any weather conditions. The completely revised mechanical design and the new integrated compact amplifier allow precisions that were previously not feasible. All signal processing is designed for minimum disruption and accurate recording of the measured data. This has, among other things, realized by ext- remely short cable runs, an optimized arrangement of the DMS and the digitization directly at the measu- ring point. The fully differential amplifier inputs of all amplifiers, including the bridge excitation ensures a maximum of noise suppression. A total of 16 in the wheel distributed thermal sensors provide also the optimal temperature compensation. Together with the high incremental angular resoluti- on of 5,000 discrete measurement points on the peri- meter guarantees the best possible accuracy.
