A method for installing a wrap spring includes providing a first sleeve with a first longitudinal axis extending in an axial direction and a lateral surface, and the wrap spring designed to frictionally abut the lateral surface. The wrap spring includes a nominal diameter and a central axis. The method includes applying the wrap spring in a relaxed state to the lateral surface at an angle α between the central axis and the first longitudinal axis, elastically twisting the wrap spring to change the nominal diameter while the wrap spring contacts the lateral surface, reducing the angle α, threading the wrap spring onto the first sleeve, and relaxing the wrap spring to establish frictional contact with the lateral surface.

A wave spring is disclosed herein that creates hysteresis between two components. The wave spring includes an annular body having a wave-shaped profile, and a plurality of axially extending fingers extending from the annular body. The wave spring is dimensioned to be received in a space between at least two axially opposed hub components.

A torsional vibration damper includes a common axis of rotation extending along an axial direction, an input part, an output part, rotatable relative to the input part in a limited manner with torque transmission, and a ramp system. The ramp system includes an axially displaceable component, a plurality of rolling elements for converting rotation of the input part relative to the output part into an axial shifting of the axially displaceable component, and a plurality of energy storage elements. The plurality of energy storage elements are arranged distributed along a circumferential direction, extend along the axial direction, and are elastically deformable in the axial direction.
