Patent ID: 7811175

Claim:
A torque transmission device, comprising: an outer tube having an outer circumference and an internal circumference with adjacent pairs of spaced sides bulging radially outwardly relative to the outer circumference between each of the pairs of spaced bulging sides, each pair defining therebetween an annular surface located radially outwardly of an annular surface between the adjacent pairs of the spaced bulging sides; an inner tube having an external circumference, said inner tube being arranged within the outer tube and having adjacent pairs of spaced sides corresponding in number and shape to the outer tube spaced sides and bulging radially outwardly toward the outer tube, each pair defining therebetween an annular surface located radially outwardly of an annular surface between the adjacent pairs of the spaced bulging sides so that a gap is provided between the internal circumference of the outer tube and the external circumference of the inner tube, with said inner and outer tubes having a predefined rotational play; spaced elastic wire-cushion-type elements arranged in the gap between the radially extending sides of the inner and outer tubes; and wherein an external circumference of the inner tube and an internal circumference of the outer tube are operatively configured to define a relative axial displacement path to provide a length compensation when the torque transmission device is subjected to a torque load.
