Abstract
A pressure generator for a hydraulic vehicle brake system includes a piston cylinder unit with a cylinder and a piston, a ball screw drive, an electric hollow-shaft motor which surrounds and is configured to drive the ball screw drive, and a planetary gear set configured to transmit a rotational movement of the hollow-shaft motor to the ball screw drive. The planetary gear set includes a planetary carrier and an internal gear which are respectfully connected via pint-type positive locking connections to a spindle nut of the ball screw drive and a static tubular force transmitter. The locking connections are configured to enable connections between parts via the respective parts being brought together axially in a hollow shaft of the hollow-shaft motor.
