Embodiment Construction

[0045] figure 1 A schematic side view of an embodiment of an actuating device according to the invention is shown. First of all, a selector lever 1 without an actuating head can be seen, and a four-joint transmission 2 supporting this selector lever 1, which consists of two pivot levers 3, 4 and by arranged on the pivot levers 3, 4. It is composed of four hinged connection links between 5. The connecting element 5 is in turn connected to the selector lever 1 and thus makes the selector lever 1 kinematically identical to the pivoting movement of the connecting element 5 of the four-joint transmission 2 .

[0046] In the illustrated embodiment of the actuating device, the four-joint transmission 2 is at a greater distance from one another than the four-joint transmission 2 on the body-side of the articulation points 6 , 7 on the side of the selector lever, ie on the upper side in the drawing. , ie the mutual spacing of the lower hinge points 8, 9 according to the drawing. Due...

Abstract

An actuating device for motor vehicle transmissions, especially for automatic transmissions has a selector lever (1), a transmission structure for sensing and transmitting the shift commands from the actuating device to the motor vehicle transmission, as well as a hinge structure with a four-bar mechanism (2) in which the selector lever (1) is mounted in such a way that it can perform shifting motions. The actuating device presents a small space requirements for installation with good ergonomic properties, good force-displacement curve at the selector lever qualities, as good sensing and signal transmission aspects. Visual shift gates and gear shifting gates can also be embodied at actuating devices of very compact design.

Description

technical field [0001] The invention relates to an actuating device for a vehicle transmission, in particular an automatic transmission. Background technique [0002] Shifting transmissions of motor vehicles are usually controlled or shifted by means of an actuating device arranged in the operating range of the driver. For this purpose, actuating elements such as joysticks or gearshift levers are often used, which are arranged, for example, between the front seats of the motor vehicle. [0003] The structural and ergonomic requirements for this type of joystick or gear lever are varied. For example, in order to convey to the driver a realistic feeling of operating the transmission, the actuating devices of this type are required to resist the actuation with a certain movement resistance, wherein a smooth and smooth movement of the actuating element is however also desired. At the same time, however, clear tactile or tactile feedback should also be sent to the driver, from ...
