Definitions

  • the present invention relates to an actuating device for a change gear of a motor vehicle having the features of the preamble of claim 1.
  • actuators for shifting and rotating a selector shaft are necessary, which as a rule comprise two levers.
  • the one lever of this arrangement usually the selector lever is pivoted to move the shift shaft axially.
  • a selection movement is transmitted to the selector lever in a linear movement of the shift shaft.
  • the other lever usually the shift lever, rotates the shift shaft e.g. for switching and engaging the gears.
  • the (shift) lever and the (selector) lever are connected via linkage, cables and the like kinematically connected to a manual shift lever or servomotors o.
  • Such actuators are known, for example, from DE 197 54 760 A1, from DE 101 11 911 A1, from DE 101 38 729 A1 and from EP 0 933 563 A1.
  • the coupling of the selector lever to the selector shaft is relatively complicated to manufacture, since a pivoting movement must be transmitted in a linear adjusting movement.
  • this engagement for coupling the two parts is usually made of sheet metal or integrated in a balance weight of a manufactured by casting component.
  • An object of the present invention is seen in a simple and cost-effective mechanical coupling between a dialing to provide at and a shift shaft of a transmission, which allows a precise transmission of a pivoting movement of the selector lever in a linear displacement of the shift shaft.
  • the present invention comprises an actuating device for a change gear of a motor vehicle with at least two levers coupled together, which cooperate with a switching shaft for their axial and radial movement.
  • a selector lever is coupled to a transmission device for the axial displacement of the shift shaft.
  • a shift lever is rotatably connected to the radial rotation of the shift shaft with this.
  • the transmission device has at least one engagement element fixed axially on the control shaft, which interacts with a coupling element which is arranged at a free end of a straight or cranked section of the pivotally mounted selector lever.
  • the engagement element is formed by a guide which cooperates with a roller which forms the coupling element which is arranged on the selector lever.
  • the engagement element may in particular be formed by two spaced webs or metal strips o. The like., Between which the coupling element and the rotatably mounted roller is guided axially.
  • the engagement member may be formed as a hub of the shift lever, which is fixedly connected to the shift shaft.
  • the guide is an integral part of the rotationally fixed and immovably fixed to the shift shaft shift lever. The guide can thus be moved and rotated axially and radially only together with the shift lever.
  • the coupling element is designed as a roller which is rotatably arranged at the free end of the straight or cranked portion of the pivotally mounted selector lever.
  • This arranged on the selector lever roller may preferably be made of plastic, but optionally also of a suitable metal. Also suitable as plastics are in particular PA or PTFE o. The like. Also, the sleeve or its guide web can optionally be made of metal, which could possibly be useful for reasons of rigidity and / or durability.

  • FIG. 1 The schematic representations of Figures 1 and 2 illustrate the structure and the operation of a first variant of an actuating device 1 for a manual transmission or change gear of a motor vehicle (not shown).
  • the actuating device 1 has a switching shaft 2 of the transmission.
  • This switching shaft 2 is rotatably and axially displaceably mounted in a transmission housing 3.
  • a shift lever 4 is fastened in a torque-proof manner, which is provided with a ball head 6 at its free end 5.

  • the shift shaft 2 can be moved in the axial direction.
  • this selector lever 7 is provided at its free end 8 with a ball head 9, to the cables or linkage connections of the manual shift lever (not shown) can attack.
  • the selector lever 7 has a pivotable mounting 10 on a carrier component 11, which may be part of the transmission housing 3.
  • the selector lever 7 has a coupling element in the form of a rotatable roller 13 which in a guide 14 in the form of two spaced-apart parallel webs 15 and Sheet metal sections is performed.
  • the guide 14 is integral with the hub 16 of the shift Hebeis 4 is formed, which is fixed against rotation and axially immovably at one end of the switching shaft 2.
  • the guide 14 and the webs 15 are axially fixed to the switching shaft 2, so that each pivotal movement of the selector lever 7 on the largely backlash-free power transmission of the mutually engaged coupling and engagement elements results directly in an axial displacement of the shift shaft 2.
  • the shift lever 4 may optionally be pressed with the shift shaft 2 in order to exclude twists.
  • Shifting lever 4 and selector lever 7 can be manufactured, in particular, from sheet-metal strips which are inexpensive to manufacture and process.

  • the same parts as in Fig. 1 are basically provided with the same reference numerals.
  • the essential difference from the first variant according to FIG. 1 and FIG. 2 is that the hub 16 of the shift lever 4 is shaped differently, so that the two sheet metal sections in the region of the hub attachment of the shift lever 4 lie flat against one another without spacing, while the webs 15 for largely play-free guidance of the roller 13 are arranged at a distance from each other, which corresponds to the diameter of the roller 13.
  • one of the two metal strips is deformed in a suitable manner, straight or cranked, which is illustrated with reference to Figures 3 and 4.
  • the remaining function and mode of action of this second variant corresponds to that of the first variant.

Abstract

La présente invention concerne un dispositif d'actionnement (1) pour une boîte de vitesses d'un véhicule à moteur, comprenant au moins deux leviers (4, 7) qui sont raccordés l'un à l'autre et qui coopèrent avec un arbre de changement de vitesse (2) pour le déplacement de ce dernier en direction axiale et radiale. Un levier de sélection (7) est raccordé à un dispositif de transmission pour le déplacement axial de l'arbre de changement de vitesse (2) et un levier de changement de vitesse (4) est relié fixe en rotation à l'arbre de changement de vitesse (2) pour la rotation radiale de ce dernier. Le dispositif de transmission comprend une coulisse (14) située sur le levier de changement de vitesse (4), laquelle coulisse est destinée à un galet (13) qui se trouve à une extrémité libre d'une section droite ou coudée (12) du levier de sélection (7) monté pivotant.
