Automated Clutch Friction Test Machine

The Automated Clutch Friction Test Machine is a laboratory test system designed to evaluate friction, wear behavior, and thermal performance of wet clutch friction components under controlled load, speed, and lubrication conditions. The machine operates using a single original-manufactured friction pair, allowing detailed analysis of friction characteristics that cannot be obtained from full clutch pack or small-scale specimen testing.

The system supports precise speed control, closed-loop load application, temperature regulation, and automated data acquisition, making it suitable for standardized clutch friction research and comparative performance evaluation.
