Abstract

An electromechanical brake pressure generator for a hydraulic braking system of a vehicle, including a threaded drive system for converting a drive-side rotary motion into a translatory motion for brake pressure generation. The system includes a spindle rotatable via an electric motor, a spindle nut cooperating with a thread of the spindle so the spindle nut is axially displaceable with a rotation of the spindle and a brake fluid is loadable or relievable, and a housing which, together with the spindle nut, forms an anti-twist protection which secures the spindle nut against twisting during rotation of the spindle. The spindle nut forms at least one spindle nut reference surface, which cooperates with at least one stop surface, which is stationary with respect to the housing, in a relief end position of the spindle nut in such a way that an instantaneous axial position of the spindle nut is determinable therefrom.
