QAT series test-bed of automatic gearbox performance is mainly used for performance testing of automatic gearbox of vehicle in big repair. QAT series test-bed apply digital inverter motor, can directly entrain rear automatic gearbox, also can entrain front automatic gearbox through automatic control of fixed platform and adjusting of rotation angle and center distance by control cabinet.

In the performance testing, by choosing different load methods according to different gearbox, QAT series test-bed can completely meet the testing requirements of various gearboxes of vehicle. Output-axis of rear automatic only need to be connected to main electrical vortex power measuring apparatus, while two output-axis of front automatic are separately connected to both electrical vortex power measuring apparatus for the experiment.
