Abstract
A torsion damping device for a vehicle drivetrain includes: a first rotary element, a second rotary element, an elastic device, a friction device including an actuating washer mounted to rotate as one with a friction washer and including an actuating tab interposed circumferentially between a first end of a spring and the first rotary element so as to allow relative rotation between the actuating washer and the second rotary element when the first end of the spring is compressed by the first rotary element in the direction of a second end of the spring opposite to the first end.
