• the invention relates to a connection arrangement for connecting a plurality of absorber mass elements by means of connecting elements for forming a damping mass, wherein the connecting elements each have a central axis in the axial direction and are each formed by a shank with bilateral shaft ends, and the shaft ends as well as the shaft in each case from the central axis enclosing inner walls are enclosed by passages of Tilgermasseniata.
• FIGS. 1 to 3 Such a connection arrangement 101 is shown in FIGS. 1 to 3, which represent the prior art.
• Fig. 1 or 2 show a Tilgersystem 102 with a Tilgermassenlie 103, which is designed as a hub disc and has guide tracks 111 (Fig. 1), in which coupling elements 115 are received relatively movable.

Since the absorber mass elements 119a and 119c continue to engage radially inward than the absorber mass elements 119b, the absorber mass elements 119a and 119c form axially between them a receiving space 105 for the absorber mass carrier 103 attached and effective in circumferential and radial direction, a relative movement of the absorber masses 118 relative to the absorber mass carrier 103 delimiting stop elements 107. The absorber mass elements 119a and 119c also limit, since they engage further radially inward than the absorber mass elements 119b, the axial relative movability of the absorber masses 118 relative to the absorber mass carrier 103.
• the absorber mass members 119 a to 119 c along central axes 121 to each other aligned passages 124 a to 124 c, of which the passage 124 a in the absorber mass element 119 a, the passage 124 b in the Tilgermas- seniden 1 19b and the passage 124c in the absorber mass element 1 19c is formed.
• the passages 124a to 124c surround the connecting elements 120 with inner walls 128a to 128c, the passage 124a encompassing a shaft end 130 of the respective connecting element 120, the passages 124b a shaft 132 and the passage 124c a shaft end 134.

• the absorber mass elements 1 19a to 1 19c are then each connected to a damping mass 1 18, in such a way that the connecting elements 120 do not protrude axially beyond the axially outer absorber mass elements 1 19a or 1 19c. As a result, an axially compact design of the absorber masses 1 18 is possible.
• the absorber mass elements 1 19a to 1 19c if a cost-optimized production is desired, usually formed by punching, and the widenings 138a and 138b by embossing. This requires several operations. If the embossing was omitted for further cost optimization, then only one punching process would be required to produce the absorber mass elements, which would allow the use of tools with fewer tooling stages and pressing with less pressing force, but then the heads 139a, 139b of the connecting elements 120 would be axially over the axially outer Tilgermassenmaschine 1 19a or 1 19c protrude, whereby the absorber masses 1 18 require more axial space, which is usually extremely limited available.
