An electrically operable drive train of a motor vehicle, including an electric motor and a transmission arrangement, in which drive train the electric motor and the transmission arrangement form a structural unit, and the structural unit includes a first housing part and a second housing part, the first housing part and/or the second housing part having fastening means which bring about predefined positioning of the first housing part relative to the second housing part, and the first housing part is formed from a metal material, the second housing part being shaped from a plastics material by means of primary shaping processes, in particular by means of an injection moulding process, and having at least one insert part which is surrounded by plastics material in such a way that it is arranged in the second housing part such that it transmits axial and/or radial force and/or torque.

Electrically operable drive train

This disclosure relates to a control valve for a hydraulic camshaft phaser. The control valve includes a screw body having a cavity, a plurality of connections opening into the cavity, and a sleeve-shaped hydraulic guide element firmly inserted radially inside the cavity. At least part of the hydraulic guide element consists of plastic. The hydraulic guide element includes a plurality of pressure medium channels which open into its radial interior, each of which is connected to at least one of the connections. A control piston is displaceably accommodated in the hydraulic guide element, and, depending on the position of the control piston, connects the connections to each other. A sealing contour provided on a radial outer side of the hydraulic guide element contacts the screw body, sealing the pressure medium channels with respect to each other and/or with respect to axial ends of the hydraulic guide element.
