In other words, the interface device 150 is designed to establish and enable an electrical connection between the inverter device 140 on the one hand and the electric machine 120 and the functional devices 132, 134 and 136 on the other hand.

[0045] The interface device 150 and the electrical connections that can be made with the aid of the interface device 150 are described in further detail with particular reference to the following figures.

[0046] Figure 2 1 shows a schematic diagram of a drive system 110 according to an embodiment. The drive system 110 corresponds to or is similar to Figure 1 Here, in Figure 2 The illustration shows an electric machine 120 in a drive system 110 including an inverter device 140 and an interface device 150 , a housing 225 of the electric machine 120 , and covering devices 245 , 255 , which are designed in two parts only as an example, for covering the inverter device 140 and the interface device 150 .

[0047] The motor 120 is at least partially arranged inside the housing 225. The inverter device 140 and the interface device 150 are arranged on the housing 225 of the motor 120 according to the embodiment shown here. The housing 225 can also be called a main housing. Here, the inverter device 140 and the interface device 150 are fastened to a partial section of the housing 225. In addition, the inverter device 140 and the interface device 150 are covered by means of a two-piece covering device 245, 255 that is formed in two pieces only as an example. The covering device 245, 255 can also be called a converter housing. Here, the partial sections of the inverter device 140 and the interface device 150 are covered by means of a first part 245 of the covering device 245, 255. The partial sections of the interface device 150 exposed by the first part 245 of the covering device 245, 255 are covered by means of a second part 255 of the covering device 245, 255. The covering device 245, 255 is mounted on the housing 225. In this case, the cover devices 245 , 255 are screwed to the housing 225 according to the exemplary embodiment shown here. The inverter device 140 and the interface device 150 are therefore arranged between a subsection of the housing 225 of the electric machine 120 and the cover devices 245 , 255 .

[0048] Figure 3 Shown is no covering device Figure 2 Schematic diagram of the drive system 110 in FIG. Therefore, the inverter device 140 and the interface device 150 are clearly visible in the figure. The inverter device 140 has a circuit board with power electronics in particular. The inverter device 140 is electrically connected to the interface device 150 by means of a plurality of AC busbars 342 for transmitting the drive current, more precisely, to the drive current section of the interface device 150.

[0049] Figure 4 Shows Figure 3 Schematic diagram of a portion of the drive system 110 in FIG. Figure 4 In the partial section shown in FIG. 1 , the housing 225 and the interface device 150 of the motor in the drive system 110 are shown. Here, the interface device 150 is mounted or fastened on the housing 225. The interface device 150 is screwed to the housing 225 according to the embodiment shown here. Figure 4 dismantled, removed or removed as shown in the illustration.

[0050] Figure 5 FIG. 1 shows a schematic diagram of an interface device 150 according to an embodiment. The interface device 150 corresponds to or is similar to the interface device in the above-mentioned figures. Figure 5 1 shows an interface device 150 in a side view. The interface device 150 has a body 552. According to the embodiment shown here, the body 552 is formed in one piece. The body 552 is formed, for example, from a plastic material.

[0051] The body 552 has an inverter side 554 or converter side 554 and a machine side 556 or motor side 556. The inverter side 554 can be electrically contacted from the side of the inverter device of the drive system. Optionally, the inverter side 554 is arranged away from the motor of the drive system and / or towards the inverter device of the drive system in the assembled state of the interface device 150. The motor side 556 can be electrically contacted from the side of the motor of the drive system. Optionally, the motor side 556 is arranged towards the motor of the drive system and / or away from the inverter device of the drive system in the assembled state of the interface device 150.

[0052] The body 552 also has a drive current section 558 and a functional current section 560. The drive current section 558 is shaped to accommodate at least one connecting element 570. According to the embodiment shown here, the drive current section 558 is shaped to accommodate six connecting elements 570 by way of example. In the drive current section 558, according to the embodiment shown here, six through-openings for accommodating the connecting elements 570 are formed for this purpose. The functional current section 560 has at least one signal input terminal 562, wherein, according to the embodiment shown here, a plurality of signal input terminals 562 are provided, and has a single signal output terminal 564. The drive current section 558 can also be referred to as a high voltage part or high voltage section of the interface device 150. The functional current section 560 can also be referred to as a low voltage part or low voltage section of the interface device 150.

[0053] The signal input terminal 562 is arranged on the motor side 556 in the functional current section 560. The signal input terminal 562 is formed to enable at least one functional device of the connection drive system. The signal output terminal 564 is arranged on the converter side 554 in the functional current section 560. The signal output terminal 564 is formed to enable the connection drive system. In addition, the signal input terminal 562 and the signal output terminal 564 are configured to conduct or transmit an electrical signal or functional signal with a first voltage between the two. Therefore, the electrical signal with a first voltage can be transmitted between the signal input terminal 562 and the signal output terminal 564. For the purpose of vivid explanation, the signal input terminal 562 is shown with a connected cable on the motor side 556. The plug position of the signal input terminal 562 can be set to be used for low-voltage components, such as, for example, temperature sensors, rotor position sensors, parking locks and similar devices, and can be expanded when necessary. The functional current section 560 is designed to bundle the signal input terminal 562 and thus the signal conducted via it onto the signal output terminal 564 and thus onto a plug or terminal.

[0054] Furthermore, according to the exemplary embodiment shown and described here, the interface device 150 has a plurality of, only exemplary six, connecting elements 570. The connecting element 570 is formed in a pin-shaped manner. Here, the connecting element 570 can also be referred to as a current pin or an AC pin. The connecting element 570 is accommodated in a drive current section 558 of the interface device 150. Here, the connecting element 570 extends from the inverter side 554 through the body 552 to the motor side 556. Specifically, the connecting element 570 extends beyond the body 552 at its two ends.

[0055] Each connecting element 570 is configured to conduct and transmit a drive current having a second voltage, more specifically, an alternating current, between the inverter device of the drive system and the motor. Here, the second voltage of the drive current has a higher value than the first voltage of the electrical signal or the functional signal transmitted in the functional current section 560. To transmit the drive current, an electrical conductor can be connected to each connecting element 570 on the inverter side 554 and the motor side 556, respectively. Figure 5 In the illustration of , for the purpose of vivid illustration, the connecting element 570 on the motor side 556 is shown with a connected cable. The connected cables represent the individual AC phases and lead to the motor. The number of connecting elements 570 can be variably matched to the system requirements, for example three-phase or six-phase, and is therefore scalable.

[0056] The body 552 also has at least one fastening section 566 for fastening the interface device 150. According to the embodiment shown here, the body 552 has only two fastening sections 566 by way of example. Each fastening section 566 is formed to fasten the interface device 150 to the housing of the motor and / or to the inverter device, in other words to the carrier structure of the drive system. According to the embodiment shown and described here, the fastening section 566 is formed as a through opening with an internal thread. For the purpose of vivid explanation, two screws are also shown as exemplary fasteners.

[0057] In other words, the interface device 150 therefore represents an AC interface with integrated low-voltage contacts. On the motor side 556, individual plugs of functional devices or low-voltage components such as temperature sensors and rotor position sensors are plugged into the signal input terminals 562 in the functional current section 560. In the functional current section 560, the signal input terminals 562 are centrally guided so that only one plug has to be plugged into the signal output terminal 564 on the converter side 554.

[0058] Figure 6 Shows Figure 5 Schematic diagram of the interface device 150 in FIG. Here, the interface device 150 is shown in a partial cross-sectional view. In addition to the different ways of illustrating, Figure 5The interface devices in correspond to the interface device 150 except that a plug pulled out from the signal input terminal 562 is also shown, and an AC busbar 342 for connecting to the connecting element 570 by means of a connecting screw 644 and a plug for connecting to the signal output terminal 564 are additionally shown.

[0059] exist Figure 6 It can be seen in the partial cross-sectional view that each connecting element 570 has a first connecting section 672 for connecting to the motor and a second connecting section 674 for electrically connecting to the inverter device. The first connecting section 672 is arranged on the motor side of the body 552. The first connecting section 672 is formed to enable a conductive extrusion connection with a cable leading to the motor. In addition, the first connecting section 672 is formed in a sleeve shape. The second connecting section 674 is arranged on the inverter side of the body 552. The second connecting section 674 is formed to enable a conductive screw connection with the AC busbar 342. Here, the second connecting section 674 is implemented as a blind hole with an internal thread for cooperating with the connecting screw 644.

[0060] In order to seal between the driving current section of the body 552 and the connecting element 570, the interface device 150 has a plurality of sealing elements 676. The sealing element 676 is formed as a sealing ring, in particular an O-ring. A sealing element 676 is arranged between each connecting element 570 and the driving current section of the body 552. In addition, the interface device 150 has a plurality of retaining elements 678 for retaining or fixing or locking the connecting element 570 in the driving current section of the body 552. The retaining element 678 is formed as a spring ring. A retaining element 678 is arranged between each connecting element 570 and the driving current section of the body 552. The connecting element 570 has a groove for accommodating the sealing element 676 and the retaining element 678.

[0061] According to the embodiment shown here, for the AC through-feed, six individual copper pins, which are crimped to the cables from the motor, are introduced as connecting elements 570 into the drive current section of the body 552. The connecting elements 570 are each sealed relative to the body 552 by an O-ring as a sealing element 676 and are fixed by a spring ring as a retaining element 678.

[0062] Figure 7 Shows that there is Figures 5 and 6 One of the interface devices 150 Figures 2 to 4Schematic diagram of a partial section of one of the drive systems 110. It is shown here that the interface device 150 is fastened to the housing 225 of the motor and is connected to the AC busbar 342 of the inverter device by means of connecting screws 644. An additional sealing element 780 for sealing is arranged between the interface device 150, more precisely the body of the interface device 150 and the housing 225 of the motor. The additional sealing element 780 is formed as a sealing ring, such as an O-ring seal, which surrounds the interface device 150. The body of the interface device 150 has a surrounding groove for accommodating the additional sealing element 780.

[0063] Figure 8 A flowchart of a method 800 for assembly according to an embodiment is shown. By implementing the method 800 for assembly, a drive system for a vehicle can be assembled. Such a drive system has a motor, an inverter device, at least one functional device for a control function for controlling the motor, and an interface device. Thus, the method 800 can be implemented to assemble a drive system of one of the above-mentioned figures.

[0064] In the method 800 for assembly, at least one connection element coupled to the motor is introduced into the drive current section of the interface device in an introduction step 810. At least one functional device is coupled to at least one signal input terminal of the interface device in a coupling step 820. The coupling step 820 may be performed before, simultaneously with, and / or after the introduction step 810.

[0065] Then, in a fastening step 830, the interface device is fastened to the housing of the electric machine and / or the inverter device. Then, in a contacting step 840, electrical contact is made between at least one connecting element of the interface device and the signal output terminal and the inverter device.

[0066] According to an embodiment, subsequently also in a covering step, at least the interface device can be covered with a covering device.

[0067] It should be noted with reference to the aforementioned figures that, according to other embodiments, as an alternative to six connection elements 570 for six AC phases, an interface device 150 with three connection elements 570 for three AC phases can be provided. Other numbers of connection elements 570 are also conceivable. Different signal input terminals 562, also referred to as low-voltage plug positions, can also be implemented as long as a plurality of plug positions are required. In addition, different screw connections can be reduced in the following manner, for example, by reducing the screw connection of the interface device 150 on the housing 225, that is, the interface device 150 is, for example, snapped, locked or clamped into the housing 225. In each case, the processing that would otherwise be required for a separate low-voltage interface in the housing 225 can be advantageously saved. The separate screw connection of such a low-voltage interface can also be omitted by the combined interface device 150.

[0068] The embodiments described and shown in the drawings are selected only as examples. Different embodiments can be combined with one another completely or with respect to individual features. Embodiments can also be supplemented by features of other embodiments.

[0069] Furthermore, method steps according to the invention may be repeated and carried out in an order other than that described.

[0070] If an exemplary embodiment includes an “and / or” relationship between a first feature and a second feature, this may be interpreted as follows: the exemplary embodiment has both the first feature and the second feature according to one embodiment, and has either only the first feature or only the second feature according to another embodiment.
