The invention relates to a hydraulic pump assembly (1) for a hydraulic vehicle brake system having a drive motor (2), preferably an electric motor, and having a piston pump (4). The invention proposes that the hydraulic pump assembly (1) has a worm gear (3), preferably a ball screw unit, which converts a rotating output movement of the drive motor (2) into a translatory drive movement of the piston pump (4) or of the pump piston (13). Further inventions relate to a method for manufacturing the hydraulic pump assembly (1) and to a vehicle brake system having the hydraulic pump assembly (1).
