To explore the substantial cause of the early abnormal wear of microvehicle
clutch’s friction material, the sample test aimed at studying the tribological
properties of micro-vehicle clutch’s friction material is designed, according to
GB/5763-98 national test standards. The broken line graph of samples’ friction
coefficient on and wear rates in different working conditions are obtained. There are
two types of working conditions. One is the same line speed and different working
loads of samples, and the other is the same working load and different line speeds.
Combined Scanning Electron Microscopy (SEM)’s observation with tribological
principle, the sample test result is analyzed, thus obtaining the changing rules of the
materials’ friction coefficient and wear rates at different temperatures, working loads
and line speeds. |
