Definitions

  • the present invention relates to a switching device for dual-clutch transmissions in motor vehicles according to the preamble of patent claim 1.
  • Such dual-clutch transmissions have, inter alia, the advantage that they can be shifted without interrupting the tractive force, wherein a forward gear is engaged and activated by means of a clutch and a second forward gear can already be preselected. By seamless transition of the two clutches of the preselected forward gear can then be activated, etc.
  • no switching device can be used, for example, as described in EP 0 615 081 A1, in which a servomotor preselection in a shift gate and a second servo motor the gear shift triggers. Both switching operations as stated above are not feasible.
  • the object of the invention is to propose a switching device for a dual-clutch transmission of the generic type, which is structurally and control technology easier and therefore less expensive.
  • the solution of this problem is achieved with the characterizing features of claim 1.
  • Advantageous and particularly useful developments of the invention are the subject of the dependent claims.
  • a switching device is provided on two adjacently arranged switching rails, which couples, for example, depending on the switching position of a further shift rail one or the other shift rail with a common gear plate. This makes it possible to save at least one gear plate with unchanged function of the transmission, whereby the structural and control engineering effort can be reduced accordingly.
  • a separately controllable hydraulic or electrically operating actuator can also be optionally provided a separately controllable hydraulic or electrically operating actuator. In this case, the switching takes place upon actuation of the actuating element.
  • a control contour may be formed on the further shift rail, which couples via the switching device depending on a neutral position of the shift rail or a gear position, the one or the other shift rail to the gear plate.
  • the switching device can be controlled, for example, electromagnetically or purely mechanically.
  • an actuating element can act on the control contour of the further shift rail, which alternately couples the two shift rails to the common gear selector via a contact pin guided movably in the changeover device.
  • This purely mechanical solution advantageously reduces the complexity of the control technology in the transmission and represents a functionally safe design.
  • one of the two shift rails which can be coupled to the gear actuator can control the reverse gear and the other shift rail Switch forward gears.
  • the switchable with forward gears on the switching means shift rail and the other shift rail in the sequence of successive forward gears can switch, so that via the respective shift rail forward gear and switchable via the respective other shift rail a next forward gear is preselected.
  • the switching device may comprise a housing fixed to the transmission housing, in which the two coupleable shift rails and connected to the gear actuator driving rail are guided axially displaceable, wherein the shift rails and the Mitauerschiene have guide slots, in which of the actuating element adjustable shift pin engages such that it alternately coupled one or the other shift rail form-fitting with the Mit predominantlyschiene.
  • the guide slots may preferably be formed in the couplable switch rails inverted L-shaped and the guide slot in the Mit favorschiene slot-shaped.
  • the actuator may be formed by a pivotally mounted on the housing, two-armed lever whose one arm on the control link of the other shift rail starts and whose other arm carries a switching pin surrounding the guide slot. This ensures a functionally reliable, advantageously adaptable to structural conditions of the transmission construction.
  • the two shift rails and the Mit supportiveschiene in the housing of the switching device can be guided axially displaceable guide rollers. Also the cooperating with the control contour of the further shift rail arm of the lever can start over a guide roller on the control contour; Furthermore, the two-armed lever of the switching device can be biased by means disposed in the housing spring against the control contour of the other shift rail.
  • the two-armed lever can also be made in two parts and mounted pivotably about an axis on the Mit supportiveschiene, wherein an inner force forming leaf spring holds the two-armed lever against internal stops in the switching pin regularly actuated configuration.
  • the lever thus acts in an advantageous manner as a one-piece component; However, for example, should the switching pin be blocked in the lower position, the control link carrying the shift rail can still be switched by overpressing the leaf spring in the corresponding forward gears.
  • Figure 1 is a schematic diagram of a switching device for a dual-clutch transmission for motor vehicles, with three shift rails and two gear actuators for forward gears and one reverse gear, and with a switching device with the two shift rails are alternately coupled to a gear plate.
