Abstract
SOUND DAMPER FOR A RUNNING WHEEL
ABSTRACT
A body sound damper for a running wheel, in particular for a track wheel comprises wave guides juxtaposed in a circumferential direction and being in the form of horn-shaped parts. The wave guides form an annular plate of such a design that at least one side of each wave guide runs tangentially towards the inside diameter of the annular plate and that, if applicable, a part of the wave guides is divided into more segments of horn-shape part. For the attenuation of the axial vibrations of the running wheel, the wave guides are bent outwardly at their outer base surface parallel to the axial direction of the running wheel and positively connected to the wheel rim of the running wheel at the bent base surface.

.
e~tending radially outwardly of the hub portion and a rim 2 e~tending around the periphery o the web portion. In accordance with ~he invention the sound damper comprises a plurality of horn-shaped circumferentially nested wave guides la, lb, lc, ld, le, lf,lg, and lh. The wave guides have axially extending circumferentially oriented edges or base surfaces 40 which are arranged circumferentially so as ~o form continuous or overlapping circumferential surfaces which are secured to the rim 2.
'- ` ''~ The'body sound damper'shown'in Fi~. 1 is assembled of wave guides10 in the form of horn-shaped parts or wave guides la to lh, ju~ta-posed in a circumferential direc-tion. The ~Ya~e guides la to lh forming the body sound damper are positively fastened to the wheel rim 2 of a track wheel. The inside diameter of the wave guides is penetrated by the wheel axle 3.
15 The German patent 31 19 4g7 is referred to for further details.
In the transverse section of the body sound damper according to Fig. 2 several superposed and congruent wave guides 4, S, 6 can be seen. The wave guides 4,5 and 6 have a base surface which are bent outwardly parallel to the a~ial direction of the trac~ wheel, 20 interconnected with sturdy washers 7 to form one common base, and joined positively to the wheel rim 2 at the bent base surface by means of screws 8. The washers 7 are located between the individual wave guides 4, S, 6. If applicable and desired, such a washer may also be disposed between the wheel rim 2 and 25 the outermost bent base of the wave guide 6. The washers in the area of the wave guide fastening assure that a certain spacing between the wave guides and possibly also the wheel rim and outermost wave guide is maintained.
Layers 9 of damping material are placed between the wave guides 30 4,5,6 in other areas, i.e. outside of the wave guide fastenings.
~:25~1~33 Each ~Yave guide la to lh ~4,5,6) .is fastened to the wheel rim 2 by at least one screw. Naturally, for static reasons, each one of the wave guides la to lh arran~ed in circumferential direction on the wheel rim 2 must have the same number of fastening screws ~.
l~hile a specific embodiment o the invention has been shown and described in detail to illustrate the application of the principles of the inventi.on, it will be understood -that the invention may be embodied otherwise ~ithou- departlng from such prlnciples.
