Abstract
A torsion damper includes an input carrier and an output carrier. The input carrier is configured to rotate about an axis and receive an input torque from a prime mover, such as an engine. An output carrier is spaced along the axis from the input carrier and is configured to transfer an output torque to a transmission component. The torsion damper includes two rings, namely a first ring connected to the input carrier and a second ring connected to the output carrier. The first and second rings are spaced apart from one another. A plurality of rolling elements are disposed between and connect the first and second rings. Rotation of the input carrier relative to the output carrier causes the rings to rotate, forcing the first ring to be in compression and the second to be in tension.
