Abstract
An improvement to a torsion damping device, especially a double damped flywheel, for eliminating contact between the springs and one of the rotatable parts of the device when the springs tend to deform under the effect of centrifugal force. According to the invention, the springs, which are conventionally mounted between two pivoted thrust members, are each replaced by a damping device comprising two springs with a central insert between them, the insert being so shaped as to make contact with the inner surface of the spacing ring. The invention is applicable to an automobile transmission.
