Piezoelectric wheel force transducers for tire test stands, Fz load ranges 30 to 100 kN / Measuring Hub for Tire Testing
Measuring Hub for Tire Testing
These multicomponent wheel force transducers measure wheel forces Fx, Fy, Fz and moments Mx, (My), Mz. They are applied for the measurement of tire non-uniformity, tire vibration, and tire characteristics.
主な特長/メリット
- Maximum measuring accuracy during high dynamic testing
- Fits to wheels with rim size 13" or larger, smaller rims may be mounted with a compatible adapter
- Fits to standard rims with interchangeable adapters, custom rims not required
- Up to 3000 rpm
- For dynamic validation of tire models
The RoaDyn P5xx wheel force transducers are robust, high-precision instruments equipped with quartz sensors. A set of 3-component force sensors is mounted with high preload between two plates. Inside, a rotating shaft with bearings holds the mounted wheel in place. The path-independent measurement of the force components naturally result in a minimum crosstalk between the components and a resonant frequency of the complete measuring system. The end of the shaft is lead through the rear side of the dynamometer and is prepared for connecting a brake or driving device. It provides an oil circulation for lubrication and cooling of the bearings, resulting in perpetual heat conditions even when high loads are applied. The mechanical interfaces for mounting on the tire test stand allow front or rear side mounting. The dynamometer is protected against corrosion, splash water and dust. The measured signals are transmitted to the charge amplifier (with summing amplifier) via a robust high-insulation cable.
