CA 2543174

A ratchet wrench has a drive-stud element with a drive stud at a first end and a drive recess at a second end. The drive-stud element is coupled with a one- way drive transmitting wheel to rotate in unison therewith about an axis. The wrench can have a centering element that resists movement of the one-way drive transmitting wheel in at least one direction away from the axis. The drive- stud element and the one-way drive transmitting wheel can be separately formed. A method is also disclosed for operating a ratchet wrench with a drive- stud element with a drive stud at a first end and a drive recess at a second end.

L'invention porte sur une clef à cliquet comportant moyeu d'entraînement présentant un embout d'entraînement à une extrémité et une cavité d'entraînement à l'autre. Ledit moyeu est solidaire d'une roue à sens unique de transmission de l'effort, tournant avec lui autour d'un axe. La clef peut en outre présenter un élément de centrage résistant aux mouvements centrifuges de la dite roue dans au moins une direction. Le moyeu et la roue peuvent être formés séparément. L'invention porte également sur le procédé d'utilisation de ladite clef
