AT/DCT/CVT Key Components

AT valve body performance test

This test bed could be used for simulations in transmission/valve development, design, and function Verification, assisting in developing control strategy, shift function curve, main pressure P-I curve and main pressure step test

Test Items

  ■ Oil pressure test of valve body oil passages

  ■ Oil pressure-flow response curve test

  ■ Endurance test for valve body

  ■ Solenoids electronic signal function

  ■ Shifting pressure

  ■ Main pressure P-I curve

  ■ Main pressure step test

AT oil pump performance test

The oil pump is driven by AC vector motors with inverter drive, to reappear established working conditions precisely and efficiently. Process parameters (Torque, rotational speed, pressure, flow, temperature, noise and vibration) been measured by high accuracy sensor, and been evaluated / compared ,  meanwhile ,these data been uploaded to data base for inquiring.

Test Items

  ■ Automatic cycle testing

  ■ P-n testing /F-n testing /P-F testing

Parameter measurement

  ■ Rotational speed, Torque, Temperature, Inlet pressure, Drain flow, Drain pressure, Vibration level, Sound pressure level
