The friction performance and the characteristics of a wet clutch operation play a critical role in the design and in the performance evaluation of wet clutch modules in automobile power transfer systems. The functionality of a wet clutch relies on frictional interactions from the combined physical contacts among the wet friction plate, separator plate, and automatic transmission oil. These interactions are limited by the frictional kinetic energy capacity of the system. Each wet clutch combination has specific frictional kinetic energy limits. Exceeding these limits can lead to critical abnormalities and system failures. As wet clutches are essential in power transfer, it is imperative to determine and define the frictional kinetic energy limit characteristics quantitatively. This can be achieved through testing by using the SAE No.2 test device. We conducted tests to verify the frictional kinetic energy limit of a wet clutch. Particularly, we explored the limits under inertial braking and continuous friction operating conditions, the representative operating conditions of the wet clutch. Based on these test results, we presented a comprehensive test methodology that defines quantitative limit ranges for the frictional kinetic energy limit characteristics of wet clutches. |
