A torsion damper comprising juxtaposed resilient plates which operate in parallel and are interposed between a support member and a hub. Each resilient plate comprises at least one resiliently deformable arm. The torsion damper has at least two pairs of similar resilient plates. One of the pairs lies between the plates of the other pair and is offset with respect to the other pair by an angle such that the two pairs of plates are radially balanced. The resilient arms of any one pair are aligned with each other.

A device with torsional damping of the kind comprising at least two coaxial parts, the device comprising a support member and a hub forming part of a first of said coaxial parts and of a second of said coaxial parts respectively, mounting means mounting the support member and said hub for relative rotation of one with respect to the other and a plurality of resilient means for resiliently opposing the relative rotation of the hub and the support member, second mounting means mounting said resilient means in parallel with each other whereby said resilient means couple the support member and the hub together, each of said resilient means being formed as a resilient plate which comprises at least one resiliently deformable arm together with inner and outer carrier rings, said arm extending between said carrier rings and being connected integrally with at least said outer carrier ring through a junction or base zone, the device further comprising first coupling means coupling said outer carrier ring with said support member of said first coaxial part of the device for rotation therewith, said resilient plates being arranged in two pairs, a first of said pairs lies axially between the resilient plates of a second of said pairs, the plates of each pair being offset circumferentially by 180 degrees with respect to those of the other pair, the resilient arms of the plates constituting each said pair being aligned with each other, said first coupling means coupling said outer carrier ring to said support member comprises at least one radially outwardly projecting element for attachment of the outer carrier ring with said support member for rotation therewith, each said radially outwardly projecting element having at least one through hole, the device further including a plurality of fastener members extending through said holes and axially joining the pairs of resilient plates together, said junction zone joining the resilient arm to the outer carrier ring also comprises a radially outwardly extending projection element which is larger than each said radially outwardly projecting element.
