ABSTRACT:
A torsion-damping device comprises two coaxial parts which are mounted to rotate relative to one another within predetermined limits of relative angular displacement and which are free axially relative to one another within the predetermined limits of axial spacing, elastic means which are interposed circumferentially between said coaxial parts and which comprise at least one block of elastically deformable material located in a housing which is fast partly with one of said coaxial parts and partly with the other of these, and friction means which act axially between said coaxial parts and which generate between them a frictional torque during their relative angular displacement each of these blocks confined circumferentially in the housing in which it is located, so that when there is a relative angular displacement between the coaxial parts, the or each block generates between the parts an axial force urging them apart, with the result that the frictional torque caused by the friction means is modulated.
