Definitions

  • the invention relates to a dual-mass flywheel with an anti-flywheel ring and an anti-flywheel flywheel which are mounted concentrically to one another and connected to one another via a torque-transmitting torsion spring and can be rotated relative to one another to a limited extent
  • Flywheels of motor vehicles with manual transmissions and a high level of comfort are usually designed as dual-mass flywheels, the flywheel ring on the other side rigidly connected to the crankshaft of the engine and the flywheel ring on the other side forming part of the motor vehicle clutch being connected to one another via at least one torsion spring.
  • the torsion spring usually consists of several, Helical compression springs arranged in circumferential direction, they serve to isolate vibrations in the drive train of the motor vehicle
  • the object of the invention is to design a two-mass flywheel of the type mentioned in such a way that, while reducing its mass, a reduction in the vibrations occurring is achieved.
  • the drive-side flywheel is connected to a hub part of a speed-adaptive vibration damper, and that several absorber masses are mounted in the hub part, each of which can be pivoted about a pivot axis running parallel and at a distance from the axis of rotation of the flywheel.
  • the arrangement of a speed-adaptive vibration damper known per se on the drive-side flywheel results in extensive extinction of the occurring torsional vibrations of the dominant order already on the drive side of the dual-mass flywheel.
  • the torsion spring can be made significantly stiffer while maintaining the output-side rotating mass; on the other hand, the output-side flywheel can be designed with a much smaller mass with a soft torsion spring, because it no longer has to dampen the torsional vibrations of the dominant order that have already been repaid on the input-side flywheel.
  • the dual mass flywheel can therefore be made much lighter overall, but at the same time a further reduction in the vibrations that occur is achieved.
  • a speed-adaptive damper on the drive-side flywheel also allows the mass and thus the inertia of the drive-side flywheel to be reduced, since the primary task of the flywheel, namely to reduce rotational irregularities, is significantly improved by the speed-adaptive damper.
  • a particularly space-saving arrangement of the speed-adaptive vibration absorber is achieved in an embodiment of the inventive concept in that the hub part of the vibration absorber is arranged on the rear side of the drive-side flywheel facing away from the drive-side flywheel, i.e. when used in a motor vehicle on the engine side of the drive-side flywheel.
  • the vibration damper there does not interfere with the arrangement of the motor vehicle clutch.
  • the hub part of the vibration damper can be screwed to the drive-side flywheel to simplify manufacture and assembly. Instead, according to another embodiment of the invention, it is also possible, for example for reasons of a particularly space-saving arrangement, to design the hub part in one piece with the drive-side flywheel.
  • FIG. 1 An exemplary embodiment of the invention is illustrated below, which is shown in the drawing.
  • the drawing shows an axial section of a two-mass flywheel 1 in a drive train of a motor vehicle, only the parts above the axis of rotation 2 being shown in section.
  • a drive-side Schwung ⁇ ng 3 is connected to the (not shown) crankshaft of the motor vehicle engine and, for example, flanged to the flange of the crankshaft by means of screws 4.
  • a torsion spring 7 is arranged between the anti-vibration ring 3 on the output side and the flywheel 5 on the driven side.
  • the torsion spring 7 has a plurality of helical compression springs 8 distributed around the circumference, which are each supported in the circumferential direction both on the drive-side flywheel 3 and on arms 9 of a transmission disk 10, which is rigidly connected to the drive-side flywheel 5 via rivets 11.
  • a clutch drive plate 12 is connected to a transmission input shaft 14 of the motor vehicle by means of a splined hub 13.
  • the clutch disc 12 is arranged between a clutch surface 14 of the drive-side flywheel 5 and a movable pressure plate 15, which is acted upon in the axial direction by a pressure spring 16 designed as a plate spring.
  • the pressure spring 16 is movably mounted on pins 17 on a clutch cover 18 connected to the drive-side flywheel 5 and is actuated by a disengaging sleeve 19 via a thrust bearing 20 designed as a roller bearing.
  • a speed-adaptive vibration damper 21 is arranged on the rear side of the drive-side flywheel ring 3 facing away from the output-side flywheel ring 5 and is rotatably connected to the drive-side flywheel ring 3 and thus also to the crankshaft of the motor vehicle engine.
  • the speed-adaptive vibration damper 21 has a hub part 22 in which a plurality of movable damper masses 23 are each pivotably mounted about a pivot axis running parallel and at a distance from the axis of rotation 2.
  • the hub part 22 is screwed to a flange 24 pointing to the axis of rotation 2 by means of the screws 4 with the drive-side flywheel 3 and the flange of the crankshaft or is connected in another manner in a positive, non-positive or material manner.
  • Each absorber mass 23 is supported with two radially projecting support surfaces 25 each on a bolt 26 which is supported at its two ends on a rolling surface 27 of the hub part 21 which is shaped concave to the axis of rotation 2. This enables the absorber masses 23 to pivot about a pivot axis that is parallel and at a distance from the axis of rotation 2.
  • a torsional vibration superimposed on the rotary movement of the crankshaft leads to the fact that the absorber masses 23, the bolts of which are partially guided by means of deformable material 28, are moved along a curved movement path which is determined by the curved paths of the surfaces 25 and 27. This results in a reduction in the distance of the absorber masses 23 from the axis of rotation 2, as a result of which the torsional vibrations are counteracted.
  • the hub part 22 is made in two parts. Its two halves 22a and 22b enclose an interior 31 which is sealed by seals 29 and 30 and which receives the damper masses 23.

Abstract

Volant (1) à deux masses pour moteurs à combustion interne, qui possède une couronne (3) de masse côté entraînement et une couronne de masse (5) côté sortie, montées concentrique, reliées entre elles par l'intermédiaire d'un ressort de torsion (7) transmettant le couple et rotatives de manière limitée l'une par rapport à l'autre. La couronne (3) de masse côté entraînement est reliée à la partie moyeu (22) d'un amortisseur de vibrations (21) adapté à la vitesse de rotation. La partie moyeu (22) comporte plusieurs masses (23) d'amortissement qui peuvent basculer autour d'un axe de basculement parallèle à l'axe de rotation (2) du volant et situé à une certaine distance de l'axe de rotation.
