Actuator assembly

The invention relates to an actuator device for an electric parking brake and/or electromechanical service brake with a brake pad adjustment unit (20) that can be driven by the actuator arrangement (10). The actuator arrangement is of modular construction and has the following components: - an electric motor (40), - a transmission unit (50) seated in a housing (90), which is coupled with the electric motor (40) and is operatively connected on the output side with the brake pad adjustment unit (20), - fastening means (60) for fastening the actuator arrangement (10) to the brake caliper (30) or the brake pad adjustment unit (20), - a plug receptacle (71) for a connector for transmitting electrical signals to the electric motor (40). In this regard, the housing (90) has a motor tube (80) that is molded on or attached, in which the electric motor (40) is accommodated, and a motor cap (81), to which the plug receptacle (71) for a connector for transmitting electrical signals to the electric motor (40) is integrally molded.
