Abstract
(EN)
A device is provided for actuating force-receiving members (32, 34) of a torque transmission apparatus. The force-receiving members (32, 34) engage first and second rotatable members (12, 14). The device includes a body (16) with a working face (72) adapted to apply a force to the force-receiving members (32, 34), wherein at least a portion of the working face (72) includes an arcuate surface (76).

(FR)
L'invention concerne un dispositif conçu pour actionner des éléments (32, 34) de réception de force d'un appareil de transmission de couple. Ces éléments (32, 34) de réception de force entrent en contact avec des premiers et second éléments (12, 14) rotatifs. Le dispositif comprend un corps (16) présentant une face (72) active conçue pour exercer une force sur les éléments (32, 34) de réception de force, au moins une partie de ladite face (72) active comprenant une surface courbe (76).
