fig1 shows , as an example , a partial view of a hybrid drive train ; in the description of the figure some components known per se are not indexed . in a familiar way , the hybrid drive train comprises an internal combustion engine ( not shown ), which is coupled by means of a clutch ( indicated only in part ) to a transmission , the clutch fork 1 provided for actuating the clutch being shown . depending on the embodiment concerned , the transmission may be a manual - shift gearbox , an automated shift transmission or the like . the transmission is arranged in a transmission housing 3 . the electric machine 2 and the clutch are accommodated in a hybrid housing 4 arranged between a crankcase ( not shown ) of the internal combustion engine and the transmission housing 3 . the proposed electric machine 2 comprises a stator support 5 formed integrally with an attachment or the like for fastening onto the hybrid housing 4 and the transmission housing 3 . thus , the electric machine 2 designed according to the invention can be adapted to the transmission housing 3 so that an ordinary transmission housing 3 , also used in drive trains without an electric drive , can be used without the need for structural modifications . the design of the stator support 5 according to the invention can be seen particularly clearly in fig2 , 3 and 4 . as the fastening attachment a flange collar 6 is formed radially on the outside on the stator support 5 . the flange collar 6 has a plurality of axially orientated through - bores 7 distributed around its circumference . the through - bores 7 receive bolts ( not shown ) to fasten the stator support 5 between the hybrid housing 4 and the transmission housing 3 . the shape of the flange collar 6 is adapted to the respective axially orientated contours of the transmission housing 3 and the hybrid housing 4 . in this way the stator support 5 can be clamped axially between the transmission housing 3 and the hybrid housing 4 , as can be seen particularly clearly in fig1 . thanks to the design of the stator support of the electric machine 2 according to the invention no additional assembly effort is involved , since the stator support 5 is only fitted axially between the hybrid housing 4 and the transmission housing 3 without the need for any shape modifications , so that only the axial length of the hybrid drive train is increased . the flange collar 6 of the stator support 5 has several cut - outs 8 , as can be seen particularly clearly in fig2 , 3 and 4 . thanks to the cut - outs 8 , on the one hand , the weight of the stator support 5 can be reduced , and , on the other hand , an appropriately positioned cut - out 8 can provide a passage for a throw - out tappet of the clutch . furthermore , a fixing strip 20 is provided on the stator support 5 . additional components can be held on the fixing strip 20 in the simplest manner . as can be seen particularly in fig4 the stator support 5 can be attached to a transport security device . this transport security device is in the form of a sheet 9 fixed by bolts to the stator support 5 . the purpose of the transport security device is to keep the stator support 5 in its correct position during transport and assembly , without the stator support 5 coming into contact with a rotor 10 of the electric machine 2 . the rotor 10 of the electric machine 2 is fixed on the rotor hub 23 . from fig5 it can be seen that the stator support 5 of the electric machine 2 has at least one integrated cooling duct 11 of a cooling system of the electric machine 2 . the cooling duct 11 runs within the stator support 5 made , for example , as a casting . as can be seen particularly in fig5 and 6 , the stator support 5 has a coolant connection for the cooling ducts 11 provided in the stator support . the coolant connection is fixed on the stator support 5 by a holding gland 12 . in this way the connection pipes 13 are connected to the cooling ducts 11 for the supply of coolant . for example , the coolant used can be water . fig6 makes it clear that the holding gland 12 for fixing the coolant connection is held tight by two fixing screws 14 . if the fixing screws 14 are loosened , the connection pipes 13 can be rotated to a desired position . in this way the connecting pipes 13 can be adapted to specific , previously positioned lines . to vent the cooling system a main bearing point 15 of the stator support 5 can preferably be used . for this , a venting screw 22 can close off an opening of the main bearing point 15 . by screwing out the venting screw 22 as necessary , the cooling system can be vented . the venting screw 22 can be seen in fig1 in particular . on the stator support 5 there is also fixed an electric current terminal box 16 . into this terminal box 16 run the three electric leads 17 connected to the respective coils 18 between the rotor 10 and the stator support 5 of the electric machine 2 , as shown in particular in fig4 . among other things , fig5 shows a current rail 19 in which the leads 17 run , the current rail 19 extending along the outside of the stator support 5 . in addition a temperature sensor connection 20 , for example a so - termed ntc plug , is provided on the stator support 5 . the temperature sensor connection 20 is arranged on the outside circumference of the stator support 5 . thus , an electric machine 2 with a compact and integrally formed stator support 5 is created , in which all the connections and interfaces required for operation are brought together .
