Abstract

A modular concept is proposed for an actuator, in particular a clutch and/or transmission actuator. An electric motor is provided with a universal flange. Through this flange it is possible to connect an electrohydraulic or electromechanical actuating link. A clutch and/or a transmission setting device can then be actuated by means of the resulting actuator. In particular, for use for an electrohydraulic actuator, the motor housing may also have a receptacle for a pressure sensor. This receptacle may already be closed, or may be closed for the connection to a mechanics module.

First claim

What is claimed is:

1 - 8 . (canceled)

9 . An actuator for clutch actuation, comprising:
a motor module; and, an actuating module.

10 . An actuator as recited in claim 9 , wherein the motor module is optionally connectible to a hydraulics module or a mechanics module.

11 . An actuator as recited in claim 9 , wherein the motor module and/or the actuating module comprises a motor flange.

12 . An actuator as recited in claim 9 , wherein the motor module and/or the actuating module comprises at least one housing flange for connecting to a housing.

13 . An actuator as recited in claim 9 , wherein the motor module has at least one closable opening to accommodate a sensor element, preferably a pressure sensor.

14 . An actuator as recited in claim 13 , wherein:
the closable opening provides an electrical connection; the motor module comprises at least one circuit element; and, the electrical connection is able to produce a connection between the sensor element and the circuit element.

15 . An actuator as recited in claim 14 , wherein the at least one circuit element is a circuit board.

16 . A drivetrain of a motor vehicle, comprising:
at least one clutch unit including at least one clutch; and, an actuator as recited in claim 9 , wherein the actuator actuates the at least one clutch.

17 . A method for providing an actuator for actuating a clutch, wherein a motor module, optionally using a hydraulics module or a mechanics module, is connected by means of a motor flange optionally to a hydraulic actuator or a mechanical actuator.
