1528673 Inertia weight vibration dampers DAIMLER-BENZ AG 24 Feb 1976 [26 Feb 1975] 7246/76 Heading F2S [Also in Division B7] A motor vehicle drive line includes a vibration damper which is adapted to damp both torsional oscillations in the drive line and flexural oscillations of propeller shaft 17 and comprises an annular oscillatory mass 10 and a rubber element 12 disposed between the inner surface of the mass 10 and a rim 14 formed around a triangular plate 13. The plate 13 is attached to a coupling flange 16 provided on the propeller shaft 17 for connection through a resilient disc 20 to a gear-box output shaft. The natural frequency of the damper is determined by the length of slits 22 formed in the rubber element 12 near the corners of the plate 13, and by the size of holes 25 in the element 12 which also permit the passage of tools for tightening screws which secure the resilient disc 20 to the gear-box output shaft. The rubber layers 24 on each side of the slits 22 serve as abutments for limiting radial run-out of the annular mass 12. |
