Abstract:
A torsion damping device, mounted between two coaxial rotating members for transmitting a rotary torque from one member to the other with damping of vibrations and torque oscillations, comprising:two rings (16, 18, 46, 48) coaxial with the two rotating members, rotational coupling means between the two rotating members and the rings, and circumferentially acting resilient members (26) mounted between the rings in housings (24, 50) which are formed in the rings and which include means for abutment of the ends of the said resilient members, characterised in that the two rings (16, 18, 46, 48) are rotatable with respect to each other and with respect to the two rotating members (10, 68, 82) with a limited angular displacement, and are the rings urged in opposite directions of rotation by the resilient members (26) toward abutment on the means for coupling them to the respective ones of the rotating members.
