<p>The transmission has jaw clutches (63, 64) comprising, at their free ends, ramps (80, 82) inclined with respect to axis of primary and secondary shafts carrying idle pinions and sleeves. The ramps guide the jaw clutches by sliding during engagement of a support when the sliding sleeve is coupled with idle pinions. The speed of rotation of the jaw clutch (63) is determined by the primary shaft rotating at a speed greater than or equal to the rotation speed of the clutch (64) whose speed is determined by the secondary shaft. An independent claim is also included for a method for controlling a transmission.</p> |
