Lubricants — Determination of the coefficient of friction of synchronizer lubricated by manual transmission fluids (MTF) — High-frequency, linear-oscillation (SRV) test machine
This document specifies a test method for determining the coefficient of friction and its evolution in mechanical transmission fluids tribologically interacting with materials used in synchronizers in manual transmission (MT) gears under high-frequency linear oscillation motion using the linear-oscillation (SRV) test machine. A flat areal contact geometry is applied.
