About the system
The drive axle and transmission fatigue bench uses AC dynamometers to test axle, transmission and differential assemblies for performance, efficiency and fatigue life. Closed-loop electrical energy recovery (>70%) cuts running costs, and the specimen is mounted in its real vehicle position. Real load-spectrum and road-load cycles run with 2 or 4 loading heads across 150–900 kW, with vibration monitoring and lube/coolant conditioning as standard.
Technical scope
- 150–900 kW
- Input up to 32 000 Nm, output up to 80 000 Nm
- 0–±3500 r/min
- 2/4 loading heads, >70% energy recovery
- Real load-spectrum tests
Test functions and capabilities
- Run-in, life and gear fatigue tests
- Efficiency and temperature rise
- Differential fatigue and impact tests
- Real load-spectrum and road-load cycles (NEDC etc.)
- Vibration monitoring and noise
- Spray, coolant and lube conditioning
