Abstract
A device for damped resilient coupling between two coaxial rotary discs, the driving disc driving the driven disc in rotation in one direction or in the other so that transmission of the drive torque may take place progressively at least within a given angular range. Each of discs (1, 2) includes for this purpose at least one rest (4, 5) for the end of a resilient torque transmission element. The resilient element is formed essentially of a composite material (3) with relatively high modulus of elasticity, and is associated with a resilient damping mass (6).
Claims11
A damped resilient coupling device for a progressive transmission of a drive torque between two coaxial and parallel rotary discs, the first rotary disc being a driving disc and the second rotary disc being a driven disc, said device comprising:
- a resilient damping mass, disposed between the discs, for providing damping of vibrations between the discs by shearing of said damping mass when the drive torque is applied to the driving disk;
- at least one blade formed of a composite material and having a relatively high modulus of elasticity with respect to said resilient damping mass, said blade being embedded in said resilient damping mass and providing a progressive transmission of the drive torque between the discs by a flexion of said blade;
- and
- a respective rest associated with a respective disc and embedded in said resilient damping mass for limiting the flexion of said blade.
