- Figure 8 a guide element in a further specific embodiment of the invention.
- a guide element is suspended consisting of one or more sheet metal parts. Due to the reduced sheet thickness, several stacked guide elements allow for small edge distances during punching and thus less space requirement for the entire guide element.
- the stack variant can also be connected by suitable methods (eg riveting) to secure the individual parts against displacement and / or misalignment.
- the receiving points in particular bearing points, designed as slots.
- Both in the radially inner and radially outer region of the guide element are recesses which allow a better reception of the elastic coupling means, in particular a spring element.
- the resilient windings of the spring element can be exposed so as to reduce the friction.
- the radially inner region is exposed more particularly in order to keep sufficient turns without contact even under rotational speed and thus spring deflection. At the same time over bending of the spring at high speeds is avoided by the remaining web.
- the guide element is designed so that in the guide area, the spring element sufficiently supported but at the same time axially slid easily.
- the edges of the guide element are additionally embossed or touched and / or rounded in the area of the spring guide.
- the guide element may be constructed in several parts.
- a one-piece variant for example, forged, sintered or conceivable consisting of plastic / aluminum injection molding and a variant of a one-piece guide element shown in Figure 7.
- FIG. 8 shows a reinforced variant with asymmetrical individual parts (due to spring mounting). The riveting can be done with compressed spring element.
- the centrifugal pendulum device 100 is rotatably mounted about an axis of rotation 105 and comprises a pendulum mass carrier 1 10, to which two or more pendulum masses 120 are attached.
- each pendulum mass 120 comprises two pendulum elements which are mounted on different axial sides of the pendulum mass support 1 10 and interconnected.
- a coupling means 130 which in each case comprises a guide element 140 and a spring element 150.
- An attachment of ends of the guide element 140 with different pendulum masses 120 is preferably carried out in each case by means of a spacer bolt 160 which runs parallel to the axis of rotation 105 through corresponding recesses of the pendulum masses 120.
- the pendulum masses 120 are slidably mounted in a known manner on the pendulum mass carrier 1 10 to form together with the pendulum mass carrier 1 10 a centrifugal pendulum for the eradication of rotational irregularities about the axis of rotation 105.
- the spring elements 150 of the coupling means 130 provide a predetermined restoring force between the pendulum masses 120.
- the guide elements 140 serve to guide the spring elements 150. This can be prevented in particular that at a high speed about the axis of rotation 105, a spring element 150 buckled, clamped between the mass ends of individual turns, broken or even flung out of the centrifugal pendulum device 100.
- Figures 2a and 2b show the coupling means 130 of Figure 1 in detail.
- the spring element 150 is preferably designed as a helical spring, in particular in a straight cylindrical shape, and extends coaxially to the guide element 140. In this case, the guide element 140 is preferably received in the interior of the spring element 150.
- the spring element 150 can bear abutting turns.
- the relative distances of abutting turns do not change as the spring element 150 compresses or expands.
- the spring element 150 rests against the guide element 140 in the region of its ends.
- the system is more preferably carried out at at least two points, of which one of the axis of rotation 105 faces.

- the guide member 140 includes a plurality of sheets stacked and preferably secured together. The attachment takes place here by means of second rivets 170 which extend through the individual sheets.
- the individual sheets can be produced inexpensively, for example by means of stamping.
- a sharp edge can be avoided, at which a portion of the spring element 150 could otherwise rub.
- the guide member 140 carries in a central portion at least one groove to increase a free movement of the spring element 150.
- the groove can be dimensioned so that a deflection of the spring element 150 is limited with respect to the rotation axis 105 radially inwardly or outwardly.
- the groove is preferably between areas at which ends of the spring element 150 rest against the guide element 140.
- FIGs 3a and 3b show an axial view of the centrifugal pendulum device 100, wherein in the representations each one facing the viewer element of the pendulum mass 120 is removed. It can thus be seen that the spacing bolt 160 runs on the guide element 140 through a slot which permits mobility of the spacing bolt 160 in the spring direction of the spring element 150. Preferably, elongated holes are inserted at both ends of the guide member 140. As a result, both a maximum and a minimum distance of the pendulum masses 120 connected to one another by means of the coupling means 130 can be defined.

It is preferred that the spring element 150 in the area in which it bears against the guide element 140, windings which abut each other, so that they do not move relative to the guide element 140 when the spring element 150 is compressed or expanded.
- the guide element 140 is preferably shaped such that the spring element 150 is spaced on all sides from the guide element 140 without the influence of centrifugal forces about the axis of rotation 105.
- Grooves, in particular on the axis of rotation 105 facing and the axis of rotation 105 facing away, can ensure this.
- the groove facing the axis of rotation 105 is greater than the groove facing away from the axis of rotation 105, so that a predetermined bending of the spring element 150 under centrifugal force upon rotation of the centrifugal pendulum device 100 is allowed around the axis of rotation 105.
- FIG. 5 shows an exploded view of the centrifugal pendulum device 100 of the preceding figures in a further embodiment.
