Definitions

  • Another form of reducing torsional vibrations is the absorber principle by which movable masses are disposed on mounting parts to counteract the effect of energy accumulators or in the case of centrifugal force pendulums, absorber masses are disposed tiltably on raceways extending in circumferential- and radially direction and hence the inertial moment of the mounting part is varied depending on vibration influences.
  • the lock-up clutch in closed state can be disposed axially in a fastening means provided radially within the outside part of the torque converter mounted in a pocket formed on the housing wall.
  • the torque converter can be disposed closely on a flex plate or a drive plate, whereby a radially disposed constriction, about the rotation axis, of the converter housing can provide axial assembly space for the crankshaft with a mounting for the flex plate.
  • the lock-up clutch furthermore can be disposed radially within the absorber masses.
  • the lock-up clutch can be equipped with a friction plate that is pressurized by a piston centered on the output hub and that is axially displaceable on the housing and non-rotatably mounted axially opposite the converter housing forming a frictional closure.
  • the torsional vibration damper 16 with the damper stages 14 , 15 is designed as a multi-function damper.
  • the two damper stages 14 , 15 are connected with one another by a single-piece disk part 25 assigned to the damper stages 14 , 15 , which is centered rotatably radially inside on the output hub 12 .
  • Radially outside is the turbine shell of the turbine 7 connected with the disk part 25 by fastening means 26 e.g. rivets.
  • the energy accumulators 27 , of the damper stage 15 formed as coil springs distributed over the circumference, are mounted in window-shaped recesses 28 , which support the energy accumulators through correspondingly formed-parts against the centrifugal force effect.
