A transmission between a gear ( 22 ) mounted freely to rotate about a shaft and a one-way drive-lock mechanism ( 26 ) for engaging in rotation the gear ( 22 ) and its shaft in a rotational direction, including a ring ( 52 ) integral in rotation with the shaft and bearing on its radial surface ( 54 ) at least two dogs ( 58 ) pivotally mounted about radial axes ( 62 ) between rest and locking positions on the gear ( 22 ) wherein they prevent the gear from rotation relative to the shaft. The invention is particularly applicable to transmission systems for a motor vehicle. |
