1. Electromechanical brake pressure generator unit of a brake-by-wire brake system, wherein the brake pressure generator unit (10) can only be activated electronically, having a master brake cylinder (20) for generating a hydraulic pressure for at least one hydraulic brake circuit, an electric motor (14), an intermediate transmission (16) driven by the electric motor (14), and a spindle-nut unit (18) having a spindle (30) which can be driven by the intermediate transmission (16) and a nut (40) which is mounted in a rotationally fixed manner and can be displaced axially by the spindle (30), wherein the nut (40) axially displaces a piston (48) which is displaceable in the master brake cylinder (20).
