Electromechanical brake pressure generator for a hydraulic brake system of a vehicle, and vehicle having an electromechanical brake pressure generator

An electromechanical brake pressure generator for a hydraulic brake system of a vehicle, comprising:

• a screw drive system configured to convert a drive-side rotary movement into an output-side translation movement;
• and
• a piston/cylinder unit which is actuable by the screw drive system to generate brake pressure;
• wherein the screw drive system includes:
• a spindle which is rotatable via an electric motor as a drive,
• a spindle nut which interacts with a thread of the spindle so that the spindle nut is axially displaced by a rotation of the spindle, and
• a drive wheel which is situated coaxially on the spindle in a torsionally fixed manner and via which the spindle is connected to the electric motor, wherein the drive wheel is formed from at least two different materials, a first material forming at least a wheel hub of the drive wheel, and a second material forming at least a drive ring enclosing the wheel hub, and the first material has greater strength than the second material.
