The drive unit 1 comprises an electric motor 3 designed as an external rotor 53 . This electric motor 3 comprises a rotor 9 which is equipped with permanent magnets 13 . The rotor 9 is fixedly connected to a rotor shaft 17 designed as a hollow shaft 19 . This rotor shaft 17 is coaxially surrounded by the stator 7 , which is arranged radially between the rotor 9 and rotor shaft 17 . The stator 7 comprises of a laminated Trä ger 6 coils 8 which can be acted upon in a predetermined manner by a control device, not shown te with current. The carrier 6 carrying the coils 8 is fixedly connected to a stator carrier 10 . Cooling channels 16 of a liquid cooling system 15 for cooling the electric motor 3 are formed in the stator carrier 10 . In the exemplary embodiment shown, a housing part 47 coaxially surrounding the rotor 9 is formed in one piece with the stator carrier 10 . In addition, the stator carrier 10 is used for mounting the rotor shaft 17 by means of bearings 49 arranged between the rotor shaft 17 and the stator carrier 10 . In the embodiment, ball bearings 50 are seen easily. The rotor shaft 17 arranged radially inside the stator 7 is provided with a toothing 24 at the end. This gear 24 is the sun gear 25 of a gear 23 Pla designated. This planetary gear 23 is provided in the transmission path between the electric motor 3 and the drive wheels of the vehicle for providing a translation of the introduced torque. This toothing 24 of the sun gear 25 is in engagement with associated planet gears 27 , which are supported against a toothing 30 , which is fixedly connected to the stator carrier 10 , of a toothed wheel designed as a ring gear 31 . The planet gears 27 are connected via the provided, the planet gears 27 journals 34 with a differential cage 35 , which at the same time represents the Pla netträger 29 . This planet carrier 29 or differential cage 35 is rotatably supported relative to the stator carrier 10 and a fixed to the stator carrier 10 connected, the differential 33 surrounding housing part 48th The differential gear 33 shown comprises a differential axis 37 on which two differential bevel wheels 39 are rotatably mounted. These differential bevel gears 39 are wheels 41 with axle shafts in engagement. These axle shaft wheels 41 are in turn firmly connected to associated output shafts 43 , 45 . Each of these output shafts 43 , 45 is rotatably connected to an associated drive wheel, not shown, of the motor vehicle. One of these output shafts 45 is rotatably supported on the one hand within the rotor shaft 17 designed as a hollow shaft 19 by means of plain bearings and in addition by means of a bearing 51 provided in a housing cover 46 .

To drive the motor vehicle, the coils 8 of the electric motor 3 are first supplied with current, which results in a rotation of the rotor 9 . About the Rotorwel le 17 is also driven with the latter integral sun gear 25 of the planetary gear 23 . So that with the sun gear 25 meshing planet gears 27 are driven, which are supported against the stationary toothing 30 Ver the ring gear 31 , so that the rotation of the planet gears 27 results in a rotation of the planet gears 27 carrying planet carrier. The speed reduction or torque ratio depends on the selected ratios of the diameter of sun gear 25 , planet gears 27 and ring gear 31 . For example, a translation can be provided in which the speed of the rotor shaft is four times as high as the speed of the output shafts when driving straight ahead. By the rotatably driven planet carrier 29 rotates with the same fixed verbun differential gear housing 35 and thus the same fixedly connected dif ferentialachse 37 on which the differential bevel gears 39 are rotatably mounted. With the differential bevel gears 39 , the shaft gears 41 connected to the output shafts 43 , 45 are engaged.

This electric motor has a stator 7 with a stator carrier 10 carrying coils 8 , which is firmly connected to a housing termination 146 . This housing termination 146 is formed in the region of the stator with outwardly pointing ribs 111 , through which in the electrical machine's, in particular in the coils 8 carried by the stator carrier 10 , heat loss is dissipated. In the illustrated embodiment, the cooling fins 111 are seen alternatively to the liquid cooling 15 shown in FIG. 1. However, there could also be cooling fins 111 in addition to liquid cooling 15 , as shown in FIG. 1. Radially inside the stator 7 , a rotor 9 is arranged, which is equipped on the side facing the stator 7 with permanent magnets 13 . The rotor 9 is rotatably connected to a hollow shaft 119 via a toothing 136 . The connection of the hollow shaft 119 to the rotor 9 by means of the toothing 136 is provided in order to make assembly easier. For the final assembly, the rotor can be pushed onto the hollow shaft 119 from the axial direction. This hollow shaft 119 is rotatably supported at one end by means of the bearing 49 , which is designed here as a ball bearing 50 , relative to the housing end, and at the other end by means of a needle bearing 137 relative to a differential cage 115 , through which a ring gear 131 of a planetary gear 123 is simultaneously formed. The Hohlwel le 119 is formed on the side facing the differential gear 123 with a Radialvor jump 128 . By this radial projection 128 a tarpaulin 129 of a planetary gear 123 connected downstream of the electrical machine is simultaneously formed. In this planet carrier 129 pins 134 are rotatably mounted, which in turn carry planet gears 127 . These planet gears 127 mesh with a sun gear 125 which is arranged in a fixed position. In the illustrated embodiment, the sun gear 125 is fixedly connected to the housing termination 146 . For support, a bearing 152 is provided between the sun wheel 125 and the hollow shaft 119 . These planet gears, which are supported in relation to the sun gear 125, are in engagement with a ring gear 131 which is fixedly connected to the differential cage 135 . When a rotary movement is initiated via the hollow shaft 119 , a reduced movement or a translated torque is transmitted to the differential basket 135 in accordance with the reduction ratio of the planetary gear. This differential cage 135 carries a differential axis 37 on which differential bevel gears 39 are rotatably mounted. These differential bevel gears in turn mesh with axle sprockets 41, each of which is firmly connected to an associated Abtriebswel le 43 , 45 . The output shaft 45 is arranged in the hollow shaft 119 and is rotatably mounted on the side facing away from the differential gear by means of the bearing 51 in the housing end 146 . The differential 33 formed by differential bevel gears 39 , axle shaft gears 41 , differential axle and differential cage is surrounded by a housing part 148 which is rotatably supported by a ball bearing 151 provided on the differential cage 135 , and that on the other hand via the component 125 formed by the sun gear firmly with the housing end 146 is connected.

The mode of operation of the drive unit 1 shown in FIG. 2 differs only from the mode of operation described with reference to FIG. 1 in that the rotary movement initiated by means of the electrical machine via the planet carrier 129 through the planet gears 127 onto the differential carrier 135 , against the sun gear 125 starting from being transferred. For this reason, a detailed description of the functioning of the exemplary embodiment according to FIG. 2 is dispensed with.
