There is a great potential for development in the field of brake technology – just think of electronic control systems, enhanced low-wear materials, or reduced brake noise. The planned new Euro standard will also have an impact on the world of brakes. The standard is expected to include both limit values for the mass of brake particles emitted and the number of brake particles. This will require special brake emission tester.
ZF supplies brake test rigs and systems for passenger cars, motorcycles, commercial vehicles, construction machinery and heavy rail vehicles.
The planned legislation in the form of a new EURO standard based on the current status will include and regulate non-internal combustion engine particulate matter in addition to the stricter exhaust emission limits. The standard is expected to include both limit values for the mass of brake particles emitted and the number of brake particles.
In order to investigate the influences (e.g. material pairing, driving cycle, temperature behavior, recuperation, etc.) on the emissions behavior of passenger car vehicle brakes, we need realistic, reliable and reproducible test bench measurement data.
The ZF test bench "dustIN" (Dust Investigator) can achieve any desired driving profiles such as WLTP Brake or California Brake Dyno Cycle (CBDC) by simulating the required vehicle inertia using superimposed electrical mass simulation.
The air conditioning on the test bench provides constant environmental conditions for a wide adjustable volume flow as well as temperature and humidity range. The CFD-optimized test piece housing ensures an even distribution of the air flowing past the DUT (Device Under Test), so that the best possible absorption of the emitted brake particles into an aerosol is ensured.
Due to the downstream isokinetic sampling (according to ISO 9096) of a partial flow by proven and adapted particle measurement devices from the exhaust emission measurement of our partner AIP Automotive, the solid and total particle number as well as the particle mass in the fractions PM10 & PM2.5 are measured.
Thanks to the modular design in the driveline, ZF offers different performance classes - from the PMP variant (GRPE-81-12-compliant) to the R&D test bench with extended temperature ranges and performance characteristics. The layout is customized so that the compact and modular design results in a minimal footprint of the overall system.
The product offers a turnkey solution for end customers such as vehicle manufacturers, brake component manufacturers as well as independent testing service providers.
