The present invention relates to a hydraulic unit with a housing in which a hydraulic converter is accommodated, which is coupled with a drive shaft that includes a connecting shaft piece located outside the housing for connection to a mechanical drive element The invention furthermore relates to a hydraulic driving device with such hydraulic unit and to a drive train connecting piece to which the hydraulic unit is connected.

It is proposed to integrate a clutch for connecting and disconnecting the hydraulic unit into the hydraulic unit itself, so that a mechanical drive train, to which the hydraulic unit is connected, can remain unchanged or need not especially be adapted to the clutch. In accordance with the invention, a clutch for coupling and uncoupling the connecting shaft piece of the hydraulic unit to and from the hydraulic converter of the hydraulic unit is accommodated in the housing of the hydraulic unit.

A clutch arrangement is provided with a clutch housing that connects a drive unit to an output, such as a transmission, which is rotatable around a central axis and with which an axial central projection is associated at the side of the clutch housing facing the drive unit in the radial extension area of its rotational center. The axial central projection receives a rotor carrier receiving a rotor of an electric machine. The central projection is connected at least so as to be fixed with respect to relative rotation to the drive unit via a first connection device and to the rotor carrier via a second connection device.

A fluid transmission device for a vehicle includes a cover and a positioning member. The cover is configured to be driven rotatably about the axis of the fluid transmission device integrally with a drive plate. The drive plate includes a positioning hole that positions the drive plate and the cover. The positioning member is a columnar member. The positioning member is provided on the surface side of the cover, which is opposed to the drive plate, at a radially outer position of the cover. The positioning member protrudes to a drive-plate side in a state where the positioning member is arranged in the positioning hole. The positioning member protrudes from the drive plate obliquely with respect to the axis direction of the fluid transmission device. A radially outermost position of the positioning member is located on the radially inner side relative to a radially outermost position of the cover.
