Why invest in an e-bench? Developing new quality engineering products consistently and having a strong place in your niche is one of the most powerful yet challenging activities. Product designers face various challenges during the development cycle, some of them are technical, others are related to external factors.

Thanks its expertise in the test bench management, GREENMOT is the ideal partner to help you define your needs and provide a bench dedicated to these specific needs.

A MULTI-PURPOSE BENCH

The e-Bench is a versatile test bench for heavy duty vehicles axles which adapts to your needs:

  • Electrified axles (wheel motor or conventional electrified) or conventional axles
  • Bus, truck, off road axles
  • Compatibility with special vehicle: 3.5m of track and 50,000 Nm / wheel

The applications are multiple:

  • Durability / reliability tests
  • Steady state and dynamic cycles, simulating on-road driving conditions
  • Performance measurement (torque)
  • Drivetrain components or system characterization
  • Driveability assessment (measurement of torque variations)
  • Overall performance measurement (electrical power / mechanical energy to the wheels
  • Electrified drivetrain power supply and control
  • Development of a driveability strategy (i.e acceleration / torque link to wheels)
