Definitions

  • the invention relates to a switching device for a change gear of a motor vehicle, with a switching shaft which is displaceable along its longitudinal axis in a selection direction and by means of a shift lever about its longitudinal axis in a switching direction.
  • Such a switching device is known from DE 10 201 1 007 251 A1.
  • the switching device usually comprises the switching shaft, which is axially displaceable by means of a selector lever. In this way, a particular lane in a transmission is selected.
  • a selector lever is provided which can be pivoted to rotate the selector shaft to engage a gear of the transmission.
  • the two levers are each connected via a cable or a linkage with a manual shift lever.
  • the invention is therefore based on the object to provide a switching device which has a simple structure and is inexpensive to produce.
  • the invention is based on the idea that a vibration decoupling between the shift lever and the shift shaft in the region of the Rastierhülse can be made.
  • the Rastierhülse and cooperating with them driver sleeve is formed so that in between at least a slight clearance in the circumferential direction is possible.
  • This game causes vibrations that arise in the transmission, are transmitted only to the drive sleeve.
  • An uninterrupted transmission of these vibrations to the Rastierhülse and thus a continuous vibration excitation is thereby prevented, accordingly these unwanted vibrations are not or attenuated transmitted via the or the cables to the manual shift lever. This ensures that these vibrations can not be perceived or reduced by the driver.
  • the switching device according to the invention is particularly well suited for versions in which arranged on the shift lever a shift weight with absorber is. Basically, however, the presence of a shift weight or a damper is not required.
  • the shift lever and the shift shaft are non-positively and / or positively and / or materially connected to each other. In this way, it is ensured that a torque can be introduced into the shift lever, for example via a ball stud, which is connected to a cable, so that the rotationally fixed to the shift lever connected shift shaft can be rotated by rotation of the shift lever, whereby a gear of the Gearbox is inserted.
  • the selector shaft has at least one stop sleeve fixedly connected to the selector shaft, which forms an axial stop for a component, in particular a detent sleeve. Accordingly, the stop sleeve prevents a displacement of the Rastierhülse in the axial direction along the shift shaft.
  • the switching device has a movably arranged on the switching shaft inner sleeve which is fixedly connected to the Rastierhülse.
  • the inner sleeve is arranged with play on the shift shaft and simultaneously connected to the Rastierhülse.
  • the driver sleeve or Rastierhülse has at least one extending in the circumferential direction recess which cooperates with a arranged on the respective other member tab to form a dog clutch.
  • the drive sleeve has the at least one recess and that the Rastierhülse has the tab which engages in the recess.
  • Recess and tab are designed so that play is provided in the circumferential direction, so that any existing vibrations can be absorbed and damped or eliminated by a movement of one of the two components.
  • the Provision of the game also allows the production of the Rastierhülse and the drive sleeve with larger tolerances, resulting in cost savings in manufacturing. The transmission of a moment only takes place when the existing clearance between the driving sleeve and the locking sleeve has been used up by a relative rotation.
  • the locking sleeve may also have on its inside at least one projection which delimits and / or defines the play in the circumferential direction.
  • the projection may be formed as a crush, whereby a cost-effective production is possible.
  • a development of the invention provides that one or each Rastierhülse each two fixed associated with the switching shaft driving sleeves are assigned. In this way, the number of required components can be reduced, resulting in a savings potential.

  • the switching device 1 shown in Figure 1 is part of a transmission of a motor vehicle.
  • the switching device 1 comprises a shift lever 2 which is rotatably connected to a shift shaft 3.
  • the shift lever 2 is arranged approximately at right angles to the shift shaft 3, so that via the shift lever 2, a torque can be introduced to rotate the shift shaft 3 about its longitudinal axis.
  • the shift lever 2 on a ball pin 4, to which a cable can be fastened, which is connectable to a manual shift lever of a motor vehicle.
  • a damper 27 is mounted with a shift weight 5.
  • the absorber 27 serves to damp the hard end stop of shift weight 5, which would occur in the operation of the switching device by the driver.
  • the absorber 27 is designed so that the transmission of vibrations is largely prevented or even suppressed.
  • the switching device 1 also includes a selector lever 6, which is also provided with a ball pin 7, and which can be connected via a second cable with the manual shift lever.
  • the selector lever 6 When the driver operates the manual shift lever, the selector lever 6 is pivoted, whereby the shift shaft 3 is moved along its longitudinal axis in a selection direction. After the correct axial position is reached, the shift lever 2 rotates the shift shaft 3, whereupon a switching operation is triggered by a arranged on the shift shaft 3 Rastierhülse 8.
  • the switching shaft 3 passes through a housing 9 of a switching dome.
  • Figure 1 can be seen on the underside of Rastierhülse 8 a fixedly connected to the shift shaft 3 driver sleeve 10, to which a Stop sleeve 1 1 connects. In the axial direction follows a switching sleeve 12, which cooperates with a further driving sleeve 13.
  • FIG. 1 shows a detail of the switching device of Figure 1 in a sectional view.
  • a torque is introduced into the switching shaft 3 by means of the shift lever 2, which is non-positively and positively connected to the shift shaft 3 via a toothing 14.
  • the Rastierhülse 8 is partially hidden by the housing 9 of the switching dome.
  • a stop sleeve 15 is fixedly connected to the switching shaft 3 and prevents displacement of the Rastierhülse 8 in the longitudinal direction of the switching shaft 3.
  • the drive sleeve 10 is fixedly connected to the shift shaft 3 and prevents on the one hand an axial displacement of the Rastierhülse 8 on the shift shaft 3 down, on the other hand it transmits via the shift lever 2 on the shift shaft 3 transmitted moment on the Rastierhülse 8.
  • FIG. 3 shows a detail of the switching device shown in FIG. 1 in a perspective view.
  • FIG. 3 shows that the driver sleeve 10 has a recess 18 extending in the circumferential direction, which cooperates with a lug 19 arranged on the detent sleeve 8 to form a dog clutch.
  • the tab 19 and the recess 18 are spaced from each other, ie on both sides of the tab 19 is a clearance or game present, the or that at least a slight relative movement between the Rastierhülse 8 and the drive sleeve 10 allows.
  • the game which allows the desired Druckdorftkopplung is shown in Figure 3 exaggerated or enlarged.
  • a torque introduced via the shift lever 2 is transmitted from the shift shaft to the drive sleeve 10 firmly connected to the shift shaft 3.
  • the space provided between the tab 19 and the recess 18 of the Rastierhülse 8 distance, d. H. the desired game, causes an interruption of the load path, which are not transmitted or only greatly attenuated to the manual shift lever, if necessary, existing vibrations or vibrations that are generated in the transmission.
  • Switching path decoupling also takes place on the switching sleeve 12 shown in FIG. 3, which interacts with the driving sleeve 13, since the switching sleeve 12 and driving sleeve 13 form a dog clutch.
