Dynamic detection system for clutch of real vehicle

Clutch is a key component in vehicle. It ensures smooth start and shift and prevents overload of transmission system. Torque capacity and heat capacity of clutch are two important technique data. Traditional detection method is to measure on a simulated working table. But the combining process of start and shift in bad condition can bring other troubles which lead to possible damage and reduce the service life of clutch. Based on clutch principle and using wireless transmission technology, the paper has designed a dynamic real-time telemetry system which can detect torque, speed and temperature in the process of separation and combination. The software is designed by Labview, it can demonstrate torque curve, temperature characteristic curves as well as the discriminate result. The system has provided technical support for vehicle and clutch manufacturers to discriminate clutch performance in working condition.
