Problems solved by technology

However, the known brake has the disadvantage that a large adjustment force is required for actuating the actuator
Since the complex structural construction requires a large number of components, it also requires a huge structural space

Embodiment Construction

[0019] exist figure 1 The general principle of action of the proposed electromechanical manipulation facility is depicted in . It follows from this illustration that an actuating device with an electric motor 1 designed as a drive drives a spindle drive 2 of an actuating device for actuating a shifting element, which is embodied as an example in these figures It is a multi-plate clutch 3. Furthermore, the adjusting device includes a toggle mechanism 4 actuated via a spindle drive 2 . The toggle mechanism 4 is spread out radially by the spindle drive 2 via the ramp profile so that with a predetermined adjustment force (F Lamelle ) to load the multi-plate clutch 3.

[0020] especially from figure 2 and image 3 As can be seen in , the adjusting device can be arranged approximately coaxially with the transmission shaft 5 of the vehicle transmission in the actuating device according to the invention, wherein the adjusting device is radially inward or radially inward with res...

Abstract

The invention relates to an electromechanical actuating assembly for at least one shifting element of a vehicle transmission, comprising at least one drive device which drives a spindle drive (2) of an adjusting device for actuating the shifting element, said adjusting device comprising a toggle joint mechanism (4) actuated by the spindle drive (2) and the adjusting device being arranged approximately coaxially relative to a gear shaft (5) of the vehicle transmission and radially inwards or radially outwards relative to the shifting element.

Description

technical field [0001] The invention relates to an electromechanical actuation arrangement for at least one shift element of a vehicle transmission according to the type defined in detail in the preamble of claim 1 . Background technique [0002] For example, documents US 2006 / 0278489 A1 and DE 10258836 A1 disclose electromechanical clutch actuators for vehicle clutches, the adjustment of which is controlled by an additional pneumatic or hydraulic system. The clutch actuator known from DE 10 258 836 A1 includes, for example, a solenoid valve, by means of which the pressure compensation channel between the two piston chambers is closed and opened in order to control the adjusting movement. This also results in complex constructions in these installations, which require an enormous amount of installation space. [0003] Furthermore, an electromechanical brake is known from DE 10156348 C1. However, the known brake has the disadvantage that a high actuating force is required f...
