Open the CIPO recordAbstract From the Canadian patent
The invention concerns 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 release can be derived either from a hydraulic actuator (18) or from axial reactive forces of the ring helical toothing 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 (V¿E?/V¿S?) and generates measured back pressure in the actuator (45) …

Why it's free to use
- Filed September 3, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 3, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 3, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
