Definitions

  • the invention relates to an actuating device for a motor vehicle transmission, in particular for an automatic transmission, according to the preamble of patent claim 1.
  • Gear change transmissions of motor vehicles are usually controlled or switched by means of an operating device arranged in the grip region of the driver. Often this come to actuators such as shifter or selector lever are used, which are arranged for example between the front seats of the motor vehicle.
  • the driver also based on the respective instantaneous position or angular position of the actuating element, for example a Selector lever to give a clear visual feedback on the current gear state or on the engaged gear.
  • a shift gate is frequently mounted in the area of the shift lever or selector lever, in whose lanes the shift lever or selector lever can move, wherein the shift gate is usually provided with symbols or numbers in the sense of a clear indication of the drive level.
  • shift-by-wire transmission in which there is usually no mechanical connection between the actuating element in the passenger compartment and the motor vehicle transmission itself more. Rather, the transmission of switching commands from the actuator to the motor vehicle transmission in the example of the shift-by-wire gearbox is usually exclusively by means of electrical or electronic signals. Also from this side therefore eliminates the need for transmission significant actuation forces or moments, which in principle no constructive requirement for expansive, long actuators or selector levers exists more.
  • actuators for motor vehicle transmissions
  • actuators such as shift handles or selector levers becoming increasingly smaller Dimensions, reduced operating forces as well as be designed with smaller switching paths.
  • the actuating device comprises a selector lever and a transmission device for transmitting the switching commands from the actuating device to the motor vehicle transmission.
  • the transmission device can be, for example, but by no means exclusively, a linkage, a cable pull or a sensor system with electrical or electronic signal transmission between the actuating device and the motor vehicle transmission.
  • the actuating device further comprises a hinge device for the switchable mounting of the control handle or selector lever within at least one selector lever movement plane.
  • the actuating device is characterized in that the joint device comprises at least one four-bar linkage which movably supports the selector lever.
  • the joint device comprises at least one four-bar linkage which movably supports the selector lever.
  • the virtual pivot point or the virtual pivot axis can be largely freely positioned in space.
  • the actuator can - despite such almost any virtual length of the selector lever - but still be made small and compact.
  • the kinematics of the actuating element which can have, for example, a higher proportion of translation while at the same time reducing the rotational component during the movement of the selector lever, also improves the operator's perceived ergonomics of the actuating element.
  • the invention can first of all realize independently of how the four-bar linkage is constructed, dimensioned and arranged, as long as the four-bar linkage allows the realization of the desired kinematics of the actuator. According to a preferred embodiment of the invention, however, the distance between the selector lever side pivot points of the four-bar linkage is greater than the distance between the body-side pivot points.
  • the four-bar linkage is arranged for switchable mounting of the selector lever in two mutually perpendicular planes of movement.
  • the selector lever can be pivoted in this way by means of the four-bar mechanism not only within a plane of movement.
  • the actuating element or the selector lever according to this embodiment of the invention by means of the four-bar mechanism for example, both be moved along the direction of travel, as well as perform additional switching operations transverse to the direction of travel.
  • speed level change lever movement in / against the direction of travel
  • shift gate change lever movement transverse to the direction of travel
  • the hinge points of the four-bar linkage are designed as ball joints.
  • the hinge points of the four-bar linkage are designed as ball joints.
  • preferred embodiments of the invention is the selector lever-side point of the transmission device or sensing for transmitting the switching commands, or the locking device for generating a defined force-displacement curve on the actuating element in each case in the region of the body-side pivot points of the four-bar linkage arranged.
  • the arrangement of the point of application of the transmission device, or the arrangement of the locking device of the actuating element in the vicinity of the body-side hinge points of the four-bar mechanism leads to a particularly compact design of the actuator, as well as and just the space in the region of the body-side end of the actuator used constructively in this way can be.
  • the tap for the transmission device or the detent device of the actuating element can therefore also be arranged in a particularly space-saving manner and in the area of the body-side pivot points of the four-bar linkage.
  • Figure 1 is a schematic side view of an embodiment of an actuating device according to the present invention.
  • FIG. 2 in a representation corresponding to FIG 1 and view an actuating device according to the prior art.
  • FIG. 3 in a Fig. 1 and 2 corresponding representation and view of the actuator of FIG. 1 during actuation.
  • Fig. 1 shows in a schematic side view of an embodiment of an actuating device according to the invention. It can be seen first of all a selector lever 1 shown without actuating knob, and a four-bar mechanism 2 which stores the selector lever 1, consisting of the two pivoting levers 3, 4 and of the four-bar linkage 5 arranged between the pivoting levers 3, 4 connected to the selector lever 1, and thus leads the selector lever 1 kinematically in accordance with the pivotal movements of the connecting member 5 of the four-bar mechanism second
  • the selector lever side so drawing related upper pivot points 6, 7 of the four-bar mechanism 2 have a greater distance from each other than the body-side, so drawing related lower pivot points 8, 9 of the four-bar mechanism 2.
  • the present invention coincides with the plane of the drawing plane of movement of the selector lever 1 on the vehicle in the vehicle longitudinal direction or in the vehicle transverse direction.
  • the respectively perpendicular to the plane of movement shown lever movement in the present case, the lever movement in the plane and out of the plane
  • the four-bar mechanism 2 can also be designed so that both lever movements as shown within the plane of the drawing, as well as lever movements perpendicular to the plane of the drawing can be performed by appropriate movements of the four-bar mechanism 2.
  • the advantages according to the invention thus come into play with lever movements both in the vehicle longitudinal direction and in the vehicle transverse direction.
  • the conventionally mounted selector lever 12 according to FIG. 2 could hardly be provided with a visually pronounced shift gate at the level E of the circuit cover, let alone - also in the amount of the plane E - equip with a shift gate.
  • the latter is mainly due to the fact that covered in switching movements lever paths of the conventional selector lever 12 in the marked in Fig. 2 area B 1 are already much too small to order there, for example between different switching levels of the selector lever 12, nor the webs of a shift gate to be able to; or to be able to attach there only a clear visualization or labeling of the different selector lever positions.
  • the conventionally mounted selector lever 12 of FIG. 2 would also bring problems in the arrangement of both the transmission device and the reliable sensing of the selector lever position, as well as in the realization of the locking of the selector lever 12 with the desired force-displacement curve with it.
  • the elements of the transmission device for example Bowden cable, linkage or the like.
  • the elements of the sensing of the selector lever position for example Hall sensors, microswitch or the like.
  • the locking device usually on the selector lever opposite side of the selector lever bearing
  • the invention thus makes a significant contribution to improving the ergonomics of the shift operation, while reducing the space requirement, in the field of actuators for motor vehicle transmission, especially in the case of demanding applications in the field of automatic transmission and the automated manual transmission.
