METHOD FOR DETERMINING A FRICTION VALUE |
摘要 |
One drive shaft (14) is driven at a certain torque (T) and the other (15) is blocked during the calibration and the operational pressure is reduced with respect to a preset temporal progression. The operational pressure at which the difference in rotational speed exceeds zero is determined. The pull-off coefficient of friction of the coupling is calculated using the operational pressure, the torque (T) and the coupling constants. |
