Abstract
In a power-shift transmission that is coupled to the engine of a vehicle and uses a frictional slip clutch as a power-shift clutch, the gear-shifting process is controlled under a method wherein the torque generated by the engine and the clutch torque transmitted through the frictional slip clutch are varied in such a manner that the temperature rise of the frictional slip clutch is lessened.
Claims22
A method of controlling a gear-shifting process in a power-shift transmission of a vehicle, wherein said power-shift transmission is coupled to an engine and is equipped with a frictional slip clutch, an input shaft and an output shaft, said engine generating an engine torque, said frictional slip clutch transmitting a clutch torque, and said power-shift transmission applying an output torque to a drive train;
- the method comprising:
- varying the engine torque and the clutch torque in such a manner that a temperature increase of the frictional slip clutch is reduced in magnitude.
