Contact is by backstop of the pin 256 on the side stopper section of slot hole 236 by gauge.
Fig. 6 is illustrated relative to Fig. 1 with section, the centrifugal force pendulum 304 of 2,4 and 5 remodeling of centrifugal force pendulum 4,104,204
Top.Slot hole in cancelling disk shaped part in centrifugal pendulum 304, so as to be set when necessary by disk shaped part 331,332
Put the closed type cage for pendulum roller 329.Such as in an illustrated embodiment, existing gap between disk shaped part 331,332
Closed by weld seam 358.The backstop vibration absorber 350 is formed between pendulum roller 329 and pendulum roller track 335.For this reason,
Pendulum roller 329 be equipped with opposite groove 359,360 in roller track 335, the elastomer element 351 the groove it
Between work.The elastomer element 351 can be used as axial guides and on disk shaped part 331, one of 332 in pendulum roller
The end of track 335 forms the elastic bolster guide portion for being used for limiting roll angle of the pendulum roller 329 in two circumferential directions.
In order to improve pendulum roller 329 relative to the axially directed of pendulum roller track 335, as being shown specifically in Fig. 7,
The annular element 361 for closing or opening wide made of such as plastics or metal, the annular can be set between groove 359,360
Component is in the groove 359 that the radially outer of elastomer element 351a is received in the pendulum roller 329.Reach pendulum here, working as
During the maximum roll angle of roller 329, annular element 361 forms the backstop relative to one or two disk shaped part 331,332
