Definitions

  • a lever spring for a torque transfer device such as coupling
  • lever elements for transmitting a force to close or open the torque transmitting device and a force edge the lever elements each having a main body with a central opening and the force edge by aligned in the circumferential direction Kraftrandringsegmente is formed, which interconnect adjacent lever elements with each other, wherein the force edge ring segments form a broken by the provided in the lever elements central openings power ring.
  • Figure 2 shows an embodiment of a lever spring 25, as they can be used for example in the double clutch 1 as a lever springs 5, 6.
  • the lever spring 25 can be used as the friction clutch to be pressed or, for example via tie rods zussende lever spring.
  • the embodiment of the lever spring 25 shown here is similar to the lever spring 6 of Figure 1 with the opposite of the lever arms 17 and the counter-ramps 15 formed on the outside, which act on corresponding tie rods and at the same time form a ramp system for adjusting the friction clutch.
  • a lever spring is a lever system with low force-edge stiffness and at the same time the highest possible lever element rigidity (tongue rigidity).
  • this desired characteristic curve which is shown schematically in FIG. 3, and in this case just the low force edge stiffness, can only be achieved by setting in the region of the force edge or by reworking the force edge (for example, machining the force edge).

Abstract

La présente invention concerne un ressort de levier pour un dispositif de transmission de couple de rotation, tel qu'un embrayage, comprenant des éléments leviers pour transmettre une force pour fermer ou ouvrir le dispositif de transmission de couple de rotation et un bord de force, les éléments leviers présentant respectivement un corps de base avec une ouverture centrale et le bord de force étant formé par des segments annulaires de bord de force qui relient les uns aux autres des éléments leviers voisins, les segments annulaires de bord de force formant une bague de force interrompue par les ouvertures centrales prévues dans les éléments leviers.
