Pressure generating apparatus for a braking system of a motor vehicle, hydraulic assemblage for interacting with the pressure generating apparatus, braking system, and method for installing a braking system for a motor vehicle

A hydraulic assemblage of a braking system for interacting with a pressure generating apparatus, comprising:

• an hydraulic assembly configured to be coupleable to a flange-shaped portion of the first housing component, and having an opening embodied so that a second, hollow-cylindrically embodied portion of the first housing component, in which a piston is axially displaceable, is insertable into the opening for receiving the first housing component;
• wherein the pressure generating apparatus includes:
• the first housing component having the flange-shaped portion to couple to the hydraulic assembly, and the hollow-cylindrically embodied portion that is insertable into the opening in the hydraulic assembly for receiving the first housing component, the piston being axially displaceable in the hollow-cylindrically embodied portion by a screw drive to generate a hydraulic pressure of the braking system, the screw drive having a nut drivable by an electric motor via a transmission gear set, and a spindle, the spindle being axially displaceable by a rotary motion of the nut, the piston being connected to the spindle of the screw drive so that the piston moves along with the spindle of the screw drive;
• and
• a second housing component having the electric motor for driving the screw drive by the transmission gear set disposed on the first housing component or on the second housing component, the first housing component and the second housing component being fitted together, along an axis disposed parallel to the axial displacement direction of the piston, so that a flange embodied on the second housing component adjacent to the first housing component, which flange is congruent with the flange-shaped portion of the first housing component, is mounted on the flange-shaped portion of the first housing component, and the second housing component completely surrounds the transmission gear set.
