Problems solved by technology

In addition to the considerable installation space required for the hydraulic actuation, the disadvantage arises that the actuation of the shift element can only take place with the internal combustion engine running.
As a result, the vehicle's stop-start function and hybrid drive capability restricted

Embodiment Construction

[0017] exist figure 1 The general principle of action of the proposed electromechanical manipulation facility is depicted in . It can be seen from this illustration that the actuating device comprises a drive wheel 2 driven by an electric motor 1 as a drive device, wherein the drive device is connected with an adjusting device for actuating a shifting element configured as a multi-plate clutch 3 connect. The adjusting device comprises a spring system operatively connected to the ball ramp 4 and an adjusting mechanism for adjusting the adjusting force acting on the ball ramp 4 for actuating the multi-plate clutch 3 . A ring gear segment 5 , which is rotatable by the drive wheel 2 , is provided as an adjustment mechanism. exist figure 1 Only two positions of the adjustment mechanism are shown by way of example in . The double arrow indicates that other intermediate positions are also possible between the two illustrated positions of the adjustment mechanism.

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 is coupled to an adjusting device for actuating the shifting element, said adjusting device comprising at least one spring system which is actively connected to a ball-shaped ramp (4) and a setting mechanism for setting the actuating force acting upon the ball-shaped ramp (4) for actuating 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] It is known from vehicle technology to hydraulically actuate shift elements in automatic transmissions. For this purpose, an oil pump is driven by the crankshaft of the vehicle's internal combustion engine, wherein the pistons for actuating the shifting elements are acted upon with hydraulic medium via the control unit and corresponding regulating valves. In addition to the considerable installation space required for the hydraulic actuation, the disadvantage arises that the actuation of the shift element can only take place with the internal combustion engine running. As a result, the vehicle's start-stop function and hybrid drive capability restricted. [0003] Furthermore, DE 102 36 516 A1 discloses an electromechanically act...
