Title:
パワーシフト変速機のギヤシフト過程の制御のための方法及び相応するパワーシフト変速機
Document Type and Number:
Japanese Patent JP4469721
Kind Code:
B2
Abstract:
A method for controlling gear-shifting processes of a powershift gearbox which can be coupled to a drive motor and has gear steps including two friction clutches and a plurality of clutches, and at least one gearbox actuator for actuating the gear steps. The method includes the following steps: the torque of the drive motor is received by the new friction clutch associated with the new gear step to be engaged; before the disengagement of the old gear step and before or during the torque reception, a pre-determined pre-tensioning force is applied to the clutch of the old gear step by the gearbox actuator; and the old gear step is disengaged when the motor torque and the clutch torque are balanced.
