摘要

Anti-shudder durability performance in a clutch friction system is a key driver in current and future transmission fluid development. Changes in the friction system during use can result in poor performance and are characterized by poor anti-shudder durability. Using an experimental friction durability test with two experimental fluids and a commercially available friction material, durability testing was completed. Analysis of the friction materials from the two tests after completion shows significant changes in the friction material surface and surface roughness. In one example, the changes in the surface are minor. This material retains significant porosity at the surface and average surface roughness of ～ 2.5 microns. In the other example, the friction material retains little residual porosity and average surface roughness of less than 1 micron. The condition of these two specimens is related to the friction vs. speed curve at the end of the test. Changes in the fluid properties of the two fluids during the durability testing are minimal in both cases.
