The development of a compact test rig designed to be able to measure subtle changes in synchronizer performance over a range of typical operating conditions is described. This rig has been used to conduct a comprehensive test programme for two different cone clutch interface materials (molybdenum sprayed and a proprietary paper-based liner) and four different lubricants (two typical mineral oils, an automatic transmission fluid, and a semi-synthetic oil). Standard statistical test techniques were used to determine statistically significant differences in the test results. Further manipulation of the meaned data has allowed trends to be identified and shortcomings of certain material/lubricant combinations to be highlighted. The development of a set of meaningful performance indicators from the experimental data is then described and finally the overall performance of each combination is expressed in the form of a new Shift Quality Index which enables quantitative comparisons to be made.
