Abstract: Chamber (11, 12, 13) for bounding a plasma generation area (42) in a vacuum pressure sensor (40), wherein the chamber comprises an electrically conductive casing element (1, 1?, 1?) located radially on the outside relative to a central axis, wherein the chamber comprises electrically conductive wall elements (2, 2?, 2?) arranged substantially perpendicular to the central axis and connected to the casing element, wherein at least one of the wall elements has a first opening (3), through which the central axis extends, wherein the casing element comprises at least a first (B1) and a second region (B2), wherein the first region is located closer to the central axis than the second region. The invention further relates to a vacuum pressure sensor comprising the chamber.

Abstract: The invention relates to a motor vehicle power train, especially for heavy-duty commercial vehicles; comprising a main drive engine, especially an internal combustion engine, comprising an output shaft for driving the drive wheels of the motor vehicle; an electric motor, comprising a rotor and a stator, also for driving the drive wheels of the motor vehicle; an automatic transmission, comprising a plurality of selectively settable drive connections for the implementation of gears, and a transmission input shaft and a transmission output shaft in order to selectively set a plurality of gear ratios between the transmission input shaft and the transmission output shaft, with the rotor of the electric motor being disposed in a drive connection between the output shaft of the main drive engine and the transmission input shaft, and can be disengaged from the output shaft by means of a clutch; at least one ancillary unit which can be driven by the main drive engine.
