Definitions

  • the invention relates to a switching device for a transmission, in particular for a change-speed gearbox of a motor vehicle, which has an actuatable by means of a shift lever shift shaft, wherein the movement of the shift lever is transmitted to at least one balance weight, which can move at a distance about a rotation axis.
  • a switching device of the generic type is known for example from DE 196 36 506 A1.
  • the boom is connected via a handlebar with the shift lever, with which the shift shaft is actuated.
  • the present invention is therefore based on the invention of a switching device of the type mentioned in such a way that even with very fast switching processes force peaks can be optimally and easily and efficiently degraded. This should further reduce the component loads occurring during fast switching operations.
  • the solu tion of this object by the invention is characterized in that the balance weight of the switching device is arranged in a guide element that it can move against the force of at least one spring element in a direction perpendicular to the axis of rotation and perpendicular to the distance vector between Rotary axis and balance weight stands.
  • the idea of the invention thus depends on the fact that the known counterweight is no longer fixed to a boom or a similar support member, but is arranged by means of a spring element elastically movable relative to this. This results in a gentler adjustment tion of the mass forces caused by the balance weight, which force peaks can be better absorbed and reduced.
  • a spring element is preferably a coil spring used.
  • the guide member may have a chamber bounded by a wall, in which the balance weight can move in said direction.
  • the direction is the tangential direction of the balance weight with respect to the axis of rotation about which the balance weight is rotatably mounted.
  • a preferred embodiment provides two spring elements between the balance weight and the axial end of the chamber.
  • the elastic movement of the balance weight is ensured relative to the guide element, d. H. a two-sided elastic suspension of the balance weight with respect to said direction.
  • the chamber and the balance weight may have a circular shape in a section perpendicular to said (tangential) direction.
  • the guide element is preferably arranged at the end of a cantilever mounted about the axis of rotation.
  • two guide elements may be arranged with respective balance weights.
  • the transmission of the movement of the shift lever to the balance weight can be done via a handlebar, which is articulated on the shift lever with a radial distance to the shift shaft and the boom at a radial distance from the axis of rotation.
  • a further preferred embodiment provides that the boom is elastically held in a zero position by means of a spring element. This defines a neutral position for the shift lever.
  • An alternative embodiment provides that the transmission of the movement from the shift lever to the balance weight via a lever which is formed elastically and with its remote from the shift shaft end engages in a backdrop in the boom.
  • the elastic design of the lever also a gentler coupling of the mass forces of the balance weights is accomplished.
  • FIG. 1 shows a perspective view of a switching device for a change-speed gearbox of a motor vehicle according to a first embodiment of the invention
  • FIG. 2 shows the boom of the switching device according to FIG. 1 with balancing weights arranged at both ends in a perspective view
  • Fig. 3 shows the boom of FIG. 2 in a sectional view

  • a hinge point 21 is arranged on the shift lever 2, to which a handlebar 14 is hingedly connected at one end. With its other end, the link 14 is connected to a boom 13 at a hinge point 22.
  • the pivot point 22 is located at a radial distance c from the axis of rotation 5, which supports the boom 13. The rotational or pivotal movement of the shift lever 2 is thereby transmitted to the boom 13.
  • An unillustrated extension of the pivot point 22 engages in a bore 19 (see Fig. 2) in the boom 13 and so defines the hinge point 22 on the boom 13.
  • a guide element 6 wherein in each guide element 6 - as will be seen in more detail - a balance weight 4 is arranged.
  • the two guide elements 6 are arranged at a radial distance from the axis of rotation 5, wherein for the one guide element 6 in Figures 1 to 3, the distance a is located. This also results in the distance vector A, which extends radially away from the axis of rotation 5 and extends to the location of the balance weight 4.
  • the cantilever 13 is held in a zero position by means of a spring element 15 designed as a torsion spring, so that the illustrated position is assumed by the switching device 1 without being subjected to external forces.
  • FIG. 3 The exact structure of the guide elements 6 and located in these balance weights 4 is apparent from Figures 2 and 3.
  • the boom 13 is mounted in a bore 18 in a suitable axis;
  • the axis of rotation 5 is defined. From this axis of rotation 5, the distance vector A extends radially to the center of mass of the balance weights 4, s.
  • FIG. 3 The guide elements 6 are shown in the exemplary embodiment. play designed as hollow cylindrical elements, have an inner wall 9 and thus define a chamber 10 for the balance weights 4.
  • the weights 4 are in the present case cylindrical.
  • the rotational movement can be introduced via the bore 18 in the boom 13.
  • FIG. 4 An alternative, but basically identical embodiment of the inventive switching device is shown in Fig. 4.
  • the boom 13 has a link 17, in which a lever 16 engages, which is fixedly arranged on the shift lever 2.
  • the lever 16 is elastically elastic, so that it has a defined Has compliance against bending moments. As a result, the transmission of movement from the shift lever 2 to the boom 13 is made softer, so that even hereby force peaks can be reduced.

Abstract

L'invention concerne un dispositif (1) de changement de rapport pour une boîte de vitesses, notamment pour une boîte de vitesses à engrenage d'un véhicule automobile, qui présente un arbre (3) de changement de rapport pouvant être actionné au moyen d'un levier (2) de changement de rapport, le mouvement du levier (2) de changement de rapport étant transmis à au moins un contrepoids (4) qui peut se déplacer à une certaine distance (a) autour d'un axe (5) de rotation. Pour pouvoir mieux affaiblir les impulsions de force lors des changements de rapport rapides, il est prévu conformément à l'invention que le contrepoids (4) soit disposé dans un élément (6) de guidage de telle sorte qu'il puisse se déplacer en contrant la force d'au moins un élément (7, 8) ressort dans une direction (B) qui est perpendiculaire à l'axe (5) de rotation et perpendiculaire au vecteur (A) d'espacement entre l'axe (5) de rotation et le contrepoids (4).
