Electromechanical brake

Abstract

The invention relates to an electromechanical brake (10) for a motor vehicle. The electromechanical brake (10) comprises an electric motor (14) arranged on a brake caliper housing (18), wherein the electric motor (14) has electrical signal lines (58) which, for signal transmission, are contacted at a connection point (70) with signal lines (62) of a control unit (38) which is arranged on a side of the brake caliper housing (18) other than the electric motor (14). The electric motor (14) drives an adjusting unit (42), via which at least one brake actuator (46) is axially movable for braking the motor vehicle. The signal lines (58) of the electric motor (14) and the signal lines (62) of the control unit (38) are contacted with one another at the connection point (70) via a welded connection.

Claims
