‘QT-DTR’ QUASI-TRANSIENT DIFFERENTIAL TEST RIG

Xtrac have a very active R&D laboratory area, which includes material research as well as transmission developments and is used for in house projects and by customers. To further increase our capabilities to support predictive modeling, we have commissioned a quasi-transient differential test rig.

This is a significant investment using our closed loop torque path concept, first seen on our 4 square rig, and will increase our understanding and calibration of mechanical plate, VCP and VLP differentials

The control system has been written by an industry renowned software developer to provide a bespoke program and will increase our capability to provide differential solutions

The QT-DTR is available for rental use on a daily basis including Xtrac technician support.  Xtrac will design and manufacture the appropriate tooling to mount the customer’s differential onto the rig, in conjunction with the customer determine the most appropriate test strategy and procedure, undertake the testing and provide a fully documented results package as required.

Specification

  • 45kW motor
  • Input torque and locking capability of 1000Nm
  • Capacity of 500rpm across the differential
  • Up to 550mm working section length
  • Can accept main types of plate, VCP and VLP differentials
  • Customisable run programs
  • An Oil System incorporated into the rig for simulating the gearbox oil system
  • Temperature controlled test environment
  • Integrated data acquisition and interpretation system, including torque, speed, and temperature sensing
  • Manual operation
  • Sequenced testing which will result in a differential characteristic map
  • Quasi-transient testing, a combination of closed/open-loop testing within a time domain to analyze differential response
  • Output data available in various recognized formats
