- the rolling element device 98 has a rolling element carrier 102.
- This WälzConsequently- carrier 102 receives the rolling elements 100 and supports them. It should be noted that the support is in particular given or can be given when centrifugal forces act on the first energy storages 68, in particular at high rotational speeds of the torsional vibration damper 10.
- the rolling element carrier 102 has a cup-shaped region 104 or a circumferentially, in particular arcuately curved and transversely to this circumferential direction, in particular arcuately curved portion 104 relative to the circumferential direction of the axis of rotation 26, which is formed in particular in the manner of a curved channel can be.
- the region 104 is arranged on the side of the rolling element carrier 102 that is radially inward relative to the radial direction of the axis of rotation 26.
- the circumferential curvature of the region 104 substantially corresponds to a curvature of the first energy store 68 designed as bow springs in this direction and / or the transverse direction given to the circumferential direction mentioned Curvature of the area 104 substantially the outer curvature of the turns of the designed as a bow springs first energy storage 68 corresponds.
- the first energy store 68 can be supported or supported on the area 104, in particular under the influence of centrifugal force.
- the rolling element carrier 102 forms mechanical holding means not shown in the figures, which engage in a first or a plurality of energy stores 68.
- the rolling element device 98 or the rolling element carrier 102 can be plugged onto a first energy store 68, specifically in the region of a winding section of the first energy store 68 located radially in the outer region relative to the radial direction of the axis of rotation 26
- a first energy store 68 specifically in the region of a winding section of the first energy store 68 located radially in the outer region relative to the radial direction of the axis of rotation 26
- the rolling bodies 100 are arranged on the radial outer side of the rolling element carrier 102, relative to the radial direction of the axis of rotation 26. This is there such that the rolling elements 100 are arranged between the rolling element carrier 102 and the first wall 92 or the first housing 94, so that they support the rolling element carrier 102 on the first wall 92 and on the first housing 94 can.
- the rolling elements 100 of the at least one rolling element device 98 are arranged such that they form a plurality of rows which are axially spaced from one another, viewed in the axial direction of the axis of rotation 26 of the torsional vibration damper 10.
- these rows are each formed by a plurality of balls or rolling elements 100, which are distributed with respect to the circumferential direction of the axis of rotation 26.
