Clutch with tangential spring bodies

A clutch having a primary part and a secondary part for coupling together two coaxial rotating shafts including a driven shaft, wherein the secondary part comprising:

• a driving disk, including a first recess with radial edges, for coupling to the primary part;
• a trailing disk, including a second recess, partially rotatable relative to said driving disk and adapted to be rigidly connected to the driven shaft;
• and
• a plurality of tangential spring bodies forming a non-positive engaging relationship between said driving disk and said trailing disk, at least one tangential spring body is a clamping body disposed within the second recess and abutting said radial edges of the first recess, said clamping body comprising:
• a cylinder having an inside diameter (D);
• a piston slidably disposed within said cylinder in an axial direction to form a closed cylinder space;
• and
• a cylindrical body, made of an elastic plastic material, disposed within the cylinder space and having a diameter (d) smaller than the inside diameter (D), wherein said cylindrical body is dimensioned to completely occupy the cylinder space upon initial axial compression of said piston whereby said cylindrical body absorbs further axial forces as an incompressible medium.
