  • the first bearing body 24c is substantially cupped. In addition to the first outer bearing surface 25, it also has an inner first bearing surface 61 facing the first fixing piece 30c.
  • the first bearing body 24c has a substantially constant material thickness.
  • the first fixing piece 30c has a complementary first abutment surface 62 facing the inner first bearing surface 61.
  • the first fixing piece 30c and the first bearing body 24c are thus tiltable relative to one another transversely to the longitudinal central axis. As a result, the ability to vibrate or the response behavior of the pendulum suspension device is further improved.
  • a first depression 64 is provided, forming a first collar surface 63 in an annular manner around the longitudinal central axis 19.
  • the first collar surface 63 extends transversely to the longitudinal central axis 19 and faces the first holding device 5. It forms a lubrication groove.
  • the second bearing body 43c is basically similar to the first bearing body 24c. It is again essentially cup-shaped and essentially has a constant material thickness. Thus, in addition to its outer second bearing surface 45, it has an inner second bearing surface 65.
  • the fixing nut 42 c has a second abutment surface 66, which is curved outwardly and is complementary to the inner second bearing surface 65 is executed.
  • the fixing nut 42c and the second bearing body 43c are tiltable relative to each other across the longitudinal center axis 19. As a result, the ability to vibrate or the response behavior of the pendulum suspension device is further improved.
  • a second recess 68 extending around the longitudinal central axis 19 is provided to form a second collar surface 67.
  • the second collar surface 67 extends transversely to the Longitudinal axis 19 and the second holding device 6 faces. It forms a lubrication groove.
  • the first attachment device 12d shown is similar to the first attachment device 12c shown in FIG Fig. 8 is shown.
  • the first fixing piece 30d has a supporting surface 69 which extends annularly around the longitudinal center axis 19 and faces the first bearing body 24d and extends transversely to the longitudinal central axis 19.
  • the support surface 69 is arranged at a distance from the first bearing body 24d.
  • the support surface 69 is formed by a ring web 70.
  • the first bearing body 24d is compliant.
  • FIG. 11 another second attachment means 15d is shown. This is similar to the embodiment according to Fig. 9 ,
  • the fixing nut 42d has a support surface 71 facing the second bearing body 43d.
  • the second support surface 71 is formed by a ring land 72.
  • the second bearing body 43d is compliant.
  • this pendulum suspension device has a particularly high vibration ability and an extremely fine response.
