Embodiment Construction

[0036] figure 1 A schematic illustration of a first embodiment of an actuation module 10 for hydraulically actuating clutch actuation or gear actuation in a clutch transmission, in particular a dual clutch transmission, is shown in . The schematic diagram shows all components as rectangles. Furthermore, the connections to one another and to the clutches are not shown. The schematic diagram should only indicate which components are used in the operating module 10 . The manipulation module 10 comprises: a reversible pump 12 for conveying a working fluid, wherein the reversible pump 12 has a first conveying direction and a conveying direction opposite to the first conveying direction; type driving device 14; and a local controller 16 for controlling the driving device 14. The reversible pump 12 , drive 14 and controller 16 together form an electric pump actuator (abbreviated EPA).

Abstract

The invention relates to a control module which is used for clutch actuation or gear actuation in a clutch transmission, particularly a double-clutch transmission in a hydraulic controlling manner. The control module comprises the components of at least one reversible pump (12,20,26) which is used for conveying working fluid, at least one electric driving device (14,22,28) which is used for controlling the reversible pump (12,20,26), and at least one local controller (16,24,30) which is used for controlling the driving device (14,22,28), wherein the reversible pump (12,20,26) has a first conveying direction and a conveying direction which is opposite to the first conveying direction. In this manner, the invention can provide a simple control module with advantages of compact structure and high integration level, and a stable structure with a short path for signal transmission and power transmission.

Description

technical field [0001] The invention relates to an actuation module for hydraulically actuating clutch actuation or gear actuation in a clutch transmission, in particular a dual clutch transmission. The actuation module can be used in particular in actuation devices such as are used on a large scale in multi-clutch transmissions of motor vehicles. Background technique [0002] The clutches for automatic shift transmissions, dual-clutch transmissions or multi-clutch transmissions as well as splitter and differential transmissions are designed as dry clutches or wet clutches. These clutches are actuated either electromechanically or hydraulically, wherein hydraulic actuation offers advantages with regard to the spatial arrangement in the transmission due to the high power density of the actuator. The clutch can thus be actuated directly (for example by means of a central clutch or a central release) and additional frictional losses are avoided by means of a mechanical transmi...
