    • A mechanism (25) for transmitting torque from one or between several torque transmitting members (14A, 16A) for which sliding in the axial direction between the torque transmitting surface(s) of the mechanism (25) and the member(s) (14A, 16A) is eliminated when the mechanism (25) is moved relative to the surfaces of the members (14A, 16A) in the direction along the axis of the mechanism (25). This is achieved by dividing the torque transmitting surfaces of the mechanism (25) into several segments (30A, B, C, D), where during any instance a/the member(s) (14A, 16A) is/are in contact with at least one segment (30A, B, C, D) and at least one segment (30A, B, C, D) is not in contact with any member (14A, 16A). During the rotation of the mechanism (25) the segments (30A, B, C, D) alternately come in and out of contact with the members (14A, 16A). When the mechanism (25) is being moved to a new desired axial position, only the segments (30A, C) not in contact with a member (14A, 16A) will be moved, while the segments (30B, D) in contact with a member (14A, 16A) will be moved after the mechanism (25) has rotated so that the segments (30A, B) that were in contact with a member (14A, 16A) are free.
    • 一种用于从一个或多个扭矩传递构件(14A,16A)之间传递扭矩的机构(25),所述扭矩传递构件(14A,16A)在所述机构(25)的扭矩传递表面与所述构件(14A)之间沿轴向方向滑动 当机构25相对于构件(14A,16A)的表面沿着机构(25)的轴线的方向移动时,消除16A,16A)。 这通过将机构(25)的扭矩传递表面分成若干段(30A,B,C,D)来实现,其中在任何情况下a /构件(14A,16A)与/ 至少一个段(30A,B,C,D)和至少一个段(30A,B,C,D)不与任何构件(14A,16A)接触。 在机构(25)的旋转期间,段(30A,B,C,D)交替地与构件(14A,16A)接触并脱离接触。 当机构(25)移动到新的期望的轴向位置时,只有不与构件(14A,16A)接触的区段(30A,C)才能移动,而与区域(30B,D)接触的区段 在机构(25)旋转之后,构件(14A,16A)将移动,使得与构件(14A,16A)接触的段(30A,B)是自由的。
