Abstract
A torsion damping device is mounted between two coaxial rotating members for transmitting a rotary toque from one member to the other with damping of vibrations and torque oscillations the damping device comprising, two rings coaxial with the rotating members, rotational coupling means between the two rotating members and the rings, circumferentially acting resilient members mounted between the rings in housing which are formed in the rings and which include a device for abutment of the ends of the resilient members, the two rings are rotatable with respect to each other and with respect to the two rotating members with a limited angular displacement, and are urged in opposite directions of rotation by the resilient members and toward abutment on the device for coupling them to the respective ones of the rotating members.
