Particularly stressed components of the driveline should already be tested as individual components. In any case, this also includes axles and couplings.

In principle, the same components are available for testing axles and couplings as for powertrain testing:

Basic system:

• RDDS automation system
• Different power units as per customer requirements, consisting of the AC motor, matching gearbox, speed/torque measurement and mounting frame (motor/generator)
• Control cabinet
• Power and signal cabling

Optional:

• Lift and swivel mounting frame for power units
• Mounting frame for test pieces
• Couplings, adapters
• Additional load application units
• Test-piece conditioning
• Special measurement technology
• Test-piece measuring box
• Feed and regenerative transformer
• Sound insulation (power units/overall system)
• Floor plate, vibration-isolated foundation
• Parallel test operation of two test setups
• Integration of MATLAB/Simulinkmodels

When testing individual components, it should always be considered to test two or even more test items at the same time in order to reduce test bench times.
