Abstract
An electromechanical brake pressure generator for a hydraulic braking system of a vehicle. The brake pressure generator includes at least one threaded drive system including a spindle and a spindle nut, which cooperate via a thread, and an electromotive drive using which the spindle and the spindle nut are rotatable relative to one another. The brake pressure generator includes a hydraulic piston accommodated in a hydraulic cylinder of a piston/cylinder unit. An anti-twist protection is formed by a recess which extends in the axial direction and forms a sliding surface, and by a sliding element protruding into the recess, so that the hydraulic piston is secured against twisting and is axially displaceable by a rotation of the spindle. The sliding surface and/or a contact surface of the sliding element cooperating with the sliding surface includes a microprofiling, whose profiling direction is orthogonal to the movement of the hydraulic piston.
