Abstract

The invention relates to a hydraulic unit for a hydraulic vehicle brake system having anti-skid control. The hydraulic unit includes a hydraulic block and an electric motor for driving hydraulic pumps inside the hydraulic block. The hydraulic block and electric motor are joined at a circumferential joint. For connection, the invention provides that the electric motor is provided with a radial flange, which is overlapped by a surrounding bead of the hydraulic block. The bead is designed so that it overlaps, in a radial inward manner, the radial flange of the electric motor by a joining process, for example, a surrounding caulking. The electric motor is sealingly connected to the hydraulic block in a simple manner by the surrounding joining process.
