Mechanism for transmitting torque between coaxial parts of transmissions and the like

A torque transmitting apparatus, comprising:

• a shaft rotatable about a predetermined axis;
• an annular member coaxially and rotatably surrounding said shaft and movable relative to said shaft In the direction of said axis;
• and
• means for transmitting torque between said shaft and said annular member, including
• first and second frames,
• a plurality of means for non-rotatably securing said first frame to said shaft,
• a plurality of means for non-rotatably mounting said second frame on said annular member, at least one of said frames being deformable in the direction of said axis, and
• a plurality of means for non-rotatably coupling one of said frames to the other of said frames,
• wherein the shaft and the annular member are axially movable relative to each other by means of a pressure built up in a pressure chamber;
• wherein the first and second frames are arranged in the pressure chamber.

A method of transmitting torque between coaxial first and second rotary members which are movable relative to each other in the direction of the common axis of said members by means of a pressure built up in a pressure chamber, comprising the steps of:

• securing circumferentially spaced apart sections of a resilient first frame inside the pressure chamber to the first member so that the thus secured first frame spacedly surrounds the common axis;
• mounting circumferentially spaced apart sections of a second frame inside the pressure chamber on the second member adjacent the first frame;
• and
• coupling the frames to each other at locations spaced apart from each other and from those sections of the first and second frames which are secured to and mounted on the respective members.
