| 摘要 |
The present invention relates to a method for adjusting the smooth engagement of a gear ratio shift wherein a planetary train (7) is engaged in direct gear by the action of centrifugal counter-weights (29) locking a clutch (18). The clutch (18) release can be derived either from a hydraulic actuator or from axial reactive forces of ring helical teeth, reaction which is transmitted by an axial stop (B2). In order to prevent the clutch (18) from being suddenly locked by the action of the counter-weights (29) in particular when the torque to be transmitted quickly disappears, a control unit (453) detects the instantaneous ratio (ViE/ViS), and generates measured backpressure in the actuator (45) while the counter-weights (29) are locking the clutch (18). |
