Experimental investigations of tribological performances of novel friction pair with different conical configurations

Friction plate with conical configuration is a novel application in automatic transmission. In order to investigate the tribological performances of novel friction pair with different conical configurations, a series of tests are conducted by using a variable-speed friction test rig. The lubrication regime is evaluated by the friction coefficient curves under different loads. Test results of the friction coefficient under different rotating speeds are analyzed. The difference in the frictional behavior is analyzed for different conical friction pairs. The effects of the cone height and cone angle are evaluated under the same dimensions. Results show that changes in the conical configuration indeed influence the frictional behaviors of the friction specimens. Rational determination of the conical configuration is helpful to obtain good tribological performance.
