| | | Kistler has specialized in wheel force measurement technology since the early 70s. About ten years after measuring hubs first found their way into the laboratories of the automobile manufacturers and related supply industry, the first piezoelectric-based measuring wheels that could also be used on vehicles were developed. Even these initial models were assembled using individual 3-component quartz sensors. Over the years these systems underwent continuous development and were complemented with other systems based on strain gages. | | | Design of measuring wheel systems Kistler RoaDyn measuring wheels are modular in design. Appropriate mechanical adapters are used to integrate the sensors into the force distribution. Modification of these adapters allows the same sensors to be used to manufacture measuring wheels for different rim sizes, wheel offsets and hub hole patterns. Mechanical adaptation of measuring wheels While the stationary conditions on a test stand often make adaptation easier, more involved adaptation is generally necessary for mounting on a vehicle. In the latter case it is particularly important to reproduce the specifications of the standard | | |
