Electromechanical brake pressure generator including spindle drive unit, braking system

An electromechanical brake pressure generator, comprising:

• a spindle drive unit configured to convert a rotational motion of an electric motor-driven drive shaft into a translatory motion of a piston that is coupled to the spindle drive unit, the spindle drive unit being operatively connected with the drive shaft via a multi-stage transmission;
• wherein the multi-stage transmission is a planetary gear set including a first and a second stage, and wherein a spindle or a spindle nut of the spindle drive unit, which is drivable using the transmission, and which is rotatably mounted in a housing of the brake pressure generator via a bearing assembly receiving axial and radial forces.
