PRESSURE GENERATOR FOR A HYDRAULIC VEHICLE BRAKE SYSTEM

摘要

The invention relates to a pressure generator (1) for a hydraulic power brake system. According to the invention, the pressure generator (1) is designed with a ball screw (8) and a planetary gear train (22), a spindle nut (7) of the ball screw (8) forming a planetary carrier (19) for planetary gears (17) of the planetary gear train (22). A sun gear (20) is mounted so as to be rotationally fixed to a hollow shaft (26) of an electric hollow shaft motor (27) and rotate along with the hollow shaft (26). The electric hollow shaft motor (27) surrounds the ball screw (7) and the planetary gear train (22).
