Driveline Testing: From Function to Durability
Our driveline test solutions provide a controlled and reproducible environment for the validation of complete driveline systems. From lubrication and ventilation investigations to functional, durability and strength testing, components can be evaluated under defined load, speed and environmental conditions.
Advanced testing supports the optimization of lubrication performance, ventilation behaviour and efficiency, including the assessment of temperature behaviour and drag losses. High dynamic tilting capabilities with longitudinal and lateral inclinations of up to ±60° and tilting speeds of up to 120°/s allow realistic operating scenarios to be replicated.
Precise test control enables functional verification such as gear shifting, clutch characteristics and NVH analysis, while durability and ultimate strength testing ensure reliable performance of critical components under both standard and extreme operating conditions—supporting confident development decisions from prototype phase through to series production.
