Definitions

  • the invention relates to a sliding sleeve of a gear wheels echseigetrsebes a motor vehicle with an internal delay line, the engagement teeth for engagement in counter teeth and stop teeth as two different Ische Zahnarte, wherein the Anschlagungszähne an axial stop for a Kup I u ngskö rpe r b i Sd e n.

At the outer periphery of the sliding sleeve a mostly formed as sine ut guide for a Schalfgafoel is provided. With the shift fork, the sliding sleeve is moved in the longitudinal direction of the gearbox on the synchronizer body until it engages. because gear is clipped or moved back to its normal position.
  • the different speeds of the shaft and the gear wheel in the egei must first be aligned with each other, so that the teeth of the Schieberauffe and the Ga g rads possible, without resistance, quiet and without damage can be pushed into one another.
  • one or more synchronizer rings are provided, which are rotatably guided with the time or with the Schsebernuffe. However, they have some margin in the circumferential direction with respect to these components.
  • the synchronizing ring is rotated relative to the sliding sleeve by the angular offset that is possible for it, as a result of which its locking toothing further biases the slides axially until the rotational speeds of the sliding muff and the gear wheel have become equal.
  • the sliding sleeve is centered in the middle on Synehron redesign held.
  • the holder is usually carried out by a plurality of locking grooves in the toothing, in which Rasteiemente can be prestressed.
  • the locking elements are often designed as a pressure piece and can initiate the Vorsynchronisationspmzess,. Due to the bias initially takes the Wenngabei the sliding sleeve together with the plungers with a switching movement of the driver. After the synchronization process has been completed, the sliding sleeve can be displaced further axially and the locking elements can disengage from their latching recesses. The carrying capacity of the teeth with the locking grooves is reduced, however. In another variant, alternate prey neuronization elements with (further) grooves so that the bearing capacity is reduced further.

  • a locking tooth 36 is shown, de in the region of its groove has a fädaiverdrfitun 42 in the circumferential direction. This eliminates adjacent teeth. Due to the displacement of the groove 39 in the abutting tooth 25, this area can be filled up with normal engagement teeth 26. Due to the axial shortening and the increase, the groove 13 can be introduced into the stop tooth 25 without affecting the adjacent teeth 26. The number of supporting flanks of the teeth 8 is thus increased.
