Thermal analysis of the synchronizer friction surface and its application to the synchronizer durability improvement

Abstract The synchronizer performance depends heavily on the friction characteristics of the synchronizer, and in particular the synchronizer durability is affected by the friction-surface temperature. In the present study, a practical thermal analysis method for the synchronizer was developed on the basis of repeated temperature-measurement on the friction surface under various test conditions. This paper describes a new analytical method for the appropriate design of the synchronizer specification.
