An electrical drive device includes a machine unit having a machine housing and power electronics having an electronics housing. At least one of the two housings having at least one protrusion for defined positioning of the machine unit and the power electronics against each other during and/or after assembly. The respective other housing having a complementary cut-out in shape and size for receiving the protrusion, wherein material forming the protrusion and the cut-out is electrically conductive at least in some sections. The protrusion and the cut-out are electrically connected to an earth for the purpose of earthing the power electronics or the machine unit. The electrical drive device and the drive assembly equipped therewith allow the electromagnetic compatibility to be optimized in a cost-effective manner.

Electrical drive device and drive assembly

A conducting element for conducting a pressurized fluid and for conducting a cooling fluid, as well as a hybrid module and a drive assembly having a hybrid module are provided. The conducting element for conducting a pressurized fluid for hydraulically actuating a clutch unit and for conducting cooling fluid for cooling a clutch unit has a cylindrical section and a securing section. At least one pressurized fluid channel is formed in the securing section for transporting pressurized fluid. The conducting element also has at least one cooling fluid channel which has at least one axial direction component in the cylindrical section, wherein the flow line element is fluidically connected to the cooling fluid channel for supplying a clutch unit and/or electric machine with cooling fluid. With this embodiment of the conducting element, a possibility for fluid conducting is created which combines the transport of cooling fluid and pressurized fluid in a fluidically separated manner and with limited axial installation space.
