On the slipping of friction clutches during gear shifting without interruption of power flow in gearboxes of cars and tractors

Sharipov V.M., Dmitriyev M.I., Zenin A.S., Malanin I.A., Smirnov I.A.


The article considers the slipping process of friction clutches in gearboxes of cars and tractors during gear shifting without interruption of power flow. It is proved that the gear shifting process in gearbox without power flow interruption occurs when clutch friction discs of engaged gear are slipping and discs of disengaging gear are closed. At this, the value of torque transmitted by disengaging friction clutch in gearbox depends on a value of frictional moment of engaging friction clutch. The results of this article also apply to composite gearboxes such as DSG (Direct Shift Gearbox).
