Experimental investigations of spontaneous damage to wet multi-plate clutches with carbon friction linings

Abstract Safety and comfort, while ensuring torque transfer capability, are essential for wet multi-plate clutches. The safety of the transmission process largely depends on endurance tribological system against spontaneous long-term damages. Modern Carbon friction linings in clutch applications offer superior wear resistance compared to other materials, but there is hardly any published data their damage behavior. This article therefore presents results from experimental studies innovative carried out a component test rig. Furthermore, influence different steel plate thicknesses (3.5 mm vs. 6 mm) was investigated. 16 step tests, including visual assessments clutches, were performed with Carbon-fiber reinforced plastic (CFRP) (C/C) brake operations. tests documented work over power diagrams. Results show excellent modern thus makes them suitable relevant high-performance applications. There no clear thickness damage. However, C/C lining ran at specific energy up 5.26 J/mm 2 combination sliding velocities 67 m/s (high speed application) without failure. highest identified
