Definitions

  • the invention relates to a multi-plate friction clutch according to the preamble of claim 1, as is known for example from DE-PS 26 01 507.
  • the teeth of the outer and inner disks engaging in grooves of an outer body and a hub body of the clutch are V-shaped, with teeth tapering towards the tooth head.
  • the clutch is to be axially displaced with a small displacement resistance, sufficient radial play of the fins must be provided, since the axial displaceability of the fins ensures that there are strong temperature fluctuations and small inclinations.
  • Di is due to the fact that, due to a force acting in the center of gravity and due to the gap between the lamella and its guidance, unstable support causes individual outer lamellae to become skewed and to abut against the inner lamella rotating in opposite directions.
  • it has already been proposed to provide spacing elements between the disks that separate the disks. Nevertheless, even with this provision, the desired parallel position of the slats cannot always be set.
  • the invention has for its object to prevent slat wobble.
  • tooth flanks that are normal to the force or displacement direction come into contact with the guide on the outer body earlier than tooth flanks lying at an angle to it or other edges of the outline of the outer lamellae and tooth flanks suitable for stable support with normal alignment to the direction of force can only be found on teeth with undercut tooth flanks.
  • Fig. 1 shows a longitudinal section through a multi-disc friction clutch
  • Fig. 2 is a cross-sectional view of the multi-plate friction clutch along the section line II-II shown in Fig. 1.
  • the outer disks 1 are coupled by teeth to an outer body 3 which is connected to a shaft 5.
  • the inner plates 2 are coupled via a toothing to a hub body 4, which is connected to a shaft 6.
  • a pressure ring 9 with a hydraulic cylinder 11 is used to actuate the clutch.
  • the axially displaceable plates are at the same distance.
  • elastic spacing elements (not shown) lying between the lamellae are used.
  • An outer plate 1 is shown in FIG. 2, which shows a sectional view of the multi-plate friction clutch along the section line II-II shown in FIG.
  • the outer lamella 1 has teeth 7 with undercut, curved tooth flanks 10.
  • the teeth 7, can also have straight tooth flanks 10, engage in grooves with corresponding undercuts in the outer body 3.
  • the outer lamella 1 shown in FIG. 2 is drawn in a position in which it would be due to a force acting in the center of gravity. As a result of the force, the outer lamella 1 hangs on the undercut tooth flanks 10 of teeth 7 which, viewed in the direction of the force, lie in front of the center of gravity, the force application point.
  • the play represented by gaps between the outer lamella 8 and the guide in the outer body 3 is exaggerated in order to give a better impression of the slipping of the outer lamella 1 as a result of the acting forces z.
  • flank areas of the outer lamella 1 that are normal to the direction of force or displacement come earlier into contact with the guide in the outer body as sloping flank areas.
  • undercut teeth 7 there are suitable normal lying tooth flanks 10 in the direction of the force in front of the center of gravity, d center of the lamellae, so that there is a stable "hanging" support shown, in the inclined position by the effect of the force acting on the center of gravity a restoring moment can be eliminated.
  • the gap between the outer lamella 1 and the outer body 3 is formed smaller in the central position of the outer lamella 1 on the tooth flanks 10 than at the other points of the contour of the outer lamella 1.
