Actuation device for a brake system, method for producing an actuation device for a brake system

An actuation device for a brake system which has an actuatable master brake cylinder, comprising:

• a gearing device which has a displaceable threaded spindle, wherein the master brake cylinder can be actuated by displacing the threaded spindle;
• an electric motor configured to drive the gearing device;
• and
• a housing in which the threaded spindle is at least partially arranged;
• wherein a rotation-locking element is connected to the threaded spindle against rotation, wherein the housing has at least one rotational counter-stop which interacts with a rotational stop of the rotation-locking element to form an anti-rotation device for the threaded spindle, and wherein the housing is an extrusion profile, and the rotational counter-stop is formed by an extrusion structure of the extrusion profile.

A method for producing an actuation device for a brake system, the method comprising the following steps:

• providing a housing with at least one rotational counter-stop and a gearing device with a displaceable threaded spindle;
• connecting a rotation-locking element to the threaded spindle against rotation;
• arranging the gearing device in such a way that the threaded spindle is at least partially arranged in the housing and a rotational stop of the rotation-locking element interacts with the rotational counter-stop of the housing to form an anti-rotation device for the threaded spindle;
• and
• operatively connection an electric motor to the gearing device in such a way that the gearing device can be driven by the electric motor;
• wherein the housing together with the rotational counter-stop is manufactured by extrusion.
