Patent Document 1

[0005] According to the present invention, an electromachine is proposed comprising at least one electromechanical component, which includes at least one first cooling plate and a further cooling plate, and which houses first and second stator members, respectively. A rotor is associated with the first and second stator members, and the first and further cooling plates are fixed to each other by a number of retaining members.

[0006] The solution proposed by the present invention allows for the replacement of jacket-like housings for electromechanical devices by using a number of retaining members, which contributes to weight reduction on the one hand and significantly reduces manufacturing costs on the other hand. The number of retaining members extending between the cooling plates may vary, and the retaining members may be formed from materials such as plastic or hybrid materials including plastic and metal parts.

[0007] In an advantageous embodiment of the electric machine according to the present invention, the first cooling plate, a further cooling plate, a second cooling plate, and the stator members associated therewith and the rotor members disposed between them are configured in a disc shape.

[0008] In the advantageous improved form of the electromachine proposed by the present invention, the electromachine is configured as an axial flux machine, a transverse flux machine, or a hybrid radial-axial flux machine (Radiax).

[0009] In the electromachine proposed by the present invention, the additional cooling plate is preferably configured as a double cooling plate. This makes it possible to modularly expand the electromachine so that it includes a first electromachine member and a second electromachine member connected by a centrally located additional cooling plate which is configured as a double cooling plate.

[0010] In an advantageous improved form of the electromachine proposed by the present invention, the electromachine has a first electromachine member and a second electromachine member connected to each other via the double cooling plate described above.

[0011] In the advantageous improved form of the electromachine proposed by the present invention, each rotor is positioned in at least one electromachine component such that it forms a gap with respect to a stator component, which is associated with the rotor and is preferably configured in a disc shape.

[0012] In the electrical machinery proposed by the present invention, numerous holding members are manufactured from lightweight plastic materials, metal materials, or hybrid materials, i.e., combinations of plastic and metal materials. This structure significantly reduces the weight of the electrical machinery proposed by the present invention without compromising its functional safety or stability.

[0013] In an advantageous embodiment of the electromachine proposed by the present invention, the retaining member is configured with a cross-section that is, for example, circular, semicircular, annular, square, hollow profile, or V-shaped. Both hollow profiles and solid materials having a cylindrical or square cross-section can be used.

[0014] In the advantageous improved form of the electromachine proposed by the present invention, the retaining members that fix the cooling plates together are configured in a V-shape, W-shape, N-shape, or I-shape. The geometric formation of such retaining members connects these retaining members to each other and provides a sufficient number of connection points on the cooling plates in which the retaining members extend.

[0015] In the electromachine proposed by the present invention, the retaining member between a cooling plate and a further cooling plate is provided with a spacer member. This allows for correction of manufacturing tolerances related to the spacing and maintenance of the gap between the components of the electromachine, namely the stator member and the rotor, and allows for adjustment of the axial gap between the end face of the stator member and the disc-shaped rotor.

[0016] In the advantageous improved form of the electromechanism proposed by the present invention, the first and second electromechanical members are provided with a semi-shell-like shielding half. This encapsulates the electromechanism from the outside, providing better sound insulation and electromagnetic compatibility.

[0017] In the electromachine proposed by the present invention, position sensors may be housed on the outer surface of the first or second cooling plate, and power electronics may be arranged on the outer or lower surface of the electromachine. The arrangement configuration of the position sensors and power electronics depends on the possible installation space when the electromachine is installed in an electric vehicle.

[0018] In an advantageous embodiment, the electromachine proposed by the present invention may be connected to a vehicle chassis by a multi-point bearing with a damping member. To accommodate various installation requirements, a rod-shaped extension may be formed between the bearing and the damping member of the multi-point bearing.

[0019] The electromechanism proposed by the present invention may consist of one electromechanical component or two adjacent electromechanical components, and a single-stage or multi-stage gear unit may be associated with one outer surface, particularly the outer surface of a first or second cooling plate. It is also possible to use an electromechanism that directly generates very high torque without the need for gears.

[0020] Furthermore, the present invention relates to the use of electromechanical devices in electric axle modules of electric-driven vehicles. [Effects of the Invention]

[0021] The electromechanical configuration proposed by the present invention, comprising at least one electromechanical component, preferably two electromechanical components arranged adjacent to each other, can significantly reduce the materials used in the manufacture of the motor housing. Furthermore, the solution proposed by the present invention can significantly reduce cost and weight. Moreover, the electromechanical configuration proposed by the present invention can be manufactured using simpler manufacturing techniques, while still maintaining the general requirements for functionality required of a motor housing. The solution proposed by the present invention ensures that the distance between individual motor components of the electromechanical device is precisely maintained using retaining members. Furthermore, the adjustment of these distances can be carried out much more easily compared to solutions in which a motor housing for an electromechanical device is provided. In addition, the solution proposed by the present invention significantly improves the noise, vibration, and harshness characteristics of the electromechanical device.

[0022] The retaining members proposed by this invention can be manufactured from any combination of plastic or low-cost materials, thereby achieving significant cost advantages in the manufacture of the electromachines proposed by this invention. Furthermore, the weight of the housing is greatly reduced. In addition, much simpler and more cost-effective manufacturing techniques can be used when manufacturing the electromachines proposed by this invention. The shielding member and semi-shell cover member provide a very simple and effective seal, protecting the internal components of the electromachine from water and dust. Moreover, the components of the electromachine proposed by this invention are encapsulated from the outside by the two semi-shell shielding members, thereby achieving lower noise emission.

[0023] The power electronics associated with the electric machine proposed by the present invention can be arranged at different installation positions according to the requirements of the automobile manufacturer. Since the power electronics can be directly connected to one of the cooling plates, which is one of the electric machine members of the electric machine proposed by the present invention, connection cables can be saved. The materials used for the shell-shaped cover and the shielding member can be selected so as to avoid electric shock during assembly or subsequent operation of the electric machine proposed by the present invention.

[0024] According to the installation requirements, the above power electronics may be associated with one of the cooling plates of the electric machine proposed by the present invention. Further, the power electronics may be arranged above and below the electric machine, or integrated with one of the cooling plates. By arranging a single-stage or multi-stage gear unit on one of the cooling plates of the first electric machine member or the second electric machine member, an electric axle module with a compact design adaptable to the installation requirements of each automobile manufacturer in terms of the available installation space can be realized.

[0025] The solution proposed by the present invention enables easy adaptation to different output powers and easy expansion. Further, it should be emphasized that the concept proposed by the present invention can achieve a modular design and significant simplification by omitting gears. Also, for example, by using a common cooling plate for the power electronics and the electric machine, a smaller and more compact design can be realized. Further, the solution proposed in the present invention is substantially cable-free, especially realizing further simplification during maintenance work.

[Figure 11] Figure 11 shows a front view and a side view of an electromachine proposed by the present invention, which includes a single-stage or multi-stage gear unit arranged laterally. [Figure 11.1] Figure 11.1 shows a front view and a side view of an electromachine proposed by the present invention, which includes a single-stage or multi-stage gear unit arranged laterally. [Modes for carrying out the invention]

[0027] In the following description, identical or similar components are denoted by the same reference numerals, and repeated descriptions of these components in individual cases are omitted. The drawings are for illustrative purposes only and represent the subject matter of the present invention.

[0028] Figure 1 shows an electromachine 10 proposed by the present invention, comprising a first electromachine member 12 and a second electromachine member 14. Figure 1.1 shows a side view of the electromachine 10 according to Figure 1.

[0029] As can be seen from the front view of the electromechanism 10 proposed by the present invention shown in Figure 1, the electromechanism 10 includes a first electromechanical member 12 and a second electromechanical member 14 arranged coaxially with respect to the first. Each of the electromechanical members 12 and 14 has a segment of the shaft 16 corresponding to it in the lateral direction.

[0030] The electromachine 10 proposed by the present invention, comprising a first electromechanical component 12, is characterized in that, instead of a machine housing made of a solid material in the form of a jacket as shown in Figure 1, a number of retaining members 36 are arranged between a first cooling plate 20 and a further centrally located cooling plate 18. As shown in Figure 1, the retaining members 36 extend between the first cooling plate 20 and the further centrally located cooling plate 18. A first stator member 24 is positioned inside the first cooling plate 20, and a second stator member 26 is positioned inside the further cooling plate 18 facing the first cooling plate 20.

[0031] A rotor 28 is located between these, positioned while forming a gap 40 between the end faces of the opposing stator members 24 and 26. The precise dimensions of the gap 40 between the individual end faces of the stator members 24 and 26 and the rotor 28 can be adjusted by spacer members 38 provided at the connection points of the retaining member 36 to the first cooling plate 20 and the connection points of the retaining member 36 to the further cooling plate 18, and can be readjusted as needed.

[0032] Since the additional cooling plate 18 is configured as a double cooling plate, it functions as a connection point for the second electromechanical member 14 to the first electromechanical member 12. The second electromechanical member 14 is configured similarly to the first electromechanical member 12. In the drawing relating to Figure 1, the retaining member 36 is omitted with respect to the second electromechanical member 14. In this embodiment, the first electromechanical member 12 and the second electromechanical member 14 are formed, for example, in a cylindrical shape. This may differ, for example, to integrate cooling channels or to secure installation space and location for connecting components arranged axially. The rotors 28 and 34 are installed between the first cooling plate 20, the additional cooling plate 18, and the second cooling plate 22 of the second electromechanical member 14. Since all components have a substantially disc-shaped configuration, the entire electromechanical unit 10 proposed by the present invention has a cylindrical appearance when viewed, for example, from the front view in Figure 1. From the drawing in Figure 1, it can be seen that the rotor 34 is positioned between the first stator member 30 and the second stator member 32, which are formed in the shape of a disc, with a gap 40 forming between them. The gap 40 is adjusted by the retaining member 36 at both ends of the retaining member 36 and can be adjusted as needed.

[0033] From the side view in Figure 1.1, it can be seen that the component unit in Figure 1 is surrounded by a first shielding half 42 and a second shielding half 44, thereby protecting the internal components of the electromachine 10 proposed by the present invention on the one hand, and attenuating noise radiation to the outside on the other hand. Semi-shell covers 46 and 48 are mounted on the first shielding half 42 and the second shielding half 44, thereby shielding the assembly of the electromachine 10 proposed by the present invention from the outside and making it accessible after removal.

[0034] The individual components of the electromachine 10 proposed by the present invention can be seen in more detail from the exploded view in Figure 2. Figure 2 shows that the first cover 46 and the second cover 48 are formed in a substantially semi-shell shape and can be screwed together along the seam. The first cover 46 and the second cover 48 enclose the first shielding half 42 and the second shielding half 44, respectively, which are configured to complement each other, and shield the internal components of the electromachine 10, including the first electromachine member 12 and the second electromachine member 14, from the outside. This ensures that the components of the electromachine 10 proposed by the present invention are reliably protected from dust and water, and furthermore, noise emission is reduced and noise, vibration, and harshness characteristics are greatly improved.

[0035] The electromechanism 10 proposed by the present invention, as shown in the perspective view of Figure 2, includes the first electromechanical member 12 and the second electromechanical member 14. The two electromechanical members 12 and 14 are connected to each other via a further cooling plate 18 that functions as a double cooling plate. The first cooling plate 20 and the second cooling plate 22 are positioned on the outside, as shown in Figure 2. The respective disc-shaped rotors 28 and 34 are positioned between the stator members 24 and 26 with respect to the first electromechanical member 12, and the rotor 34 of the second electromechanical member 14 is between the stator members 30 and 32, with the two rotors 28 and 34 positioned relative to the stator members 24 and 26 and the stator members 30 and 32, forming a gap 40.

[0036] Figures 3 and 3.1 show a front view and a side view of the electromachine 10 proposed by the present invention as shown in Figures 1 and 1.1. From the drawing in Figure 3, it can be seen that the power electronics 50 is installed on the outer surface 54 of the first cooling plate 20. The power electronics 50 surrounds the position sensor 52, which is also provided on the outer surface 54 of the first cooling plate 20 of the first electromachine member 12. As an alternative to the embodiment shown in Figure 3, the power electronics 50 may be housed together with the position sensor 52 on the outer surface of the second cooling plate 22 of the second electromachine member 14.

[0037] Similar to the drawings in Figures 1 and 1.1, the first cooling plate 20 and the further cooling plate 18, which functions as a double cooling plate, are connected to each other by a number of retaining members 36. The exact distance between the first cooling plate 20 and the further cooling plate 18 is set by spacer members 38 located at the connection points of the retaining members 36, and may be adjusted by replacing the spacer members if necessary.

[0038] Figure 3, which shows a side view of the electromachine 10, shows that the power electronics 50 in this modified embodiment have a substantially circular appearance and surround the position sensor 52. The power electronics 50 may have a rectangular design or a different geometric shape. Similar to the drawing in Figure 1.1, the electromachine 10 is surrounded by shell-shaped covers 46, 48, which surround the first and second shielding halves 42, 44.

[0039] Unlike the electromachine 10 proposed by the present invention in Figures 1 and 1.1, and Figures 3 and 3.1, in the embodiment of the electromachine 10 proposed by the present invention in Figures 4 and 4.1, the power electronics 50 are located, for example, on the lower surface 55 of the electromachine 10, and here below the second electromachine member 14. The position sensor 52 is located on the outer surface 54 of the first cooling plate 20, as in the drawings of the electromachine 10 proposed by the present invention in Figures 3 and 3.1. Figure 4.1 shows the position of the power electronics 50 mounted on the lower surface 55 of the electromachine 10, and further, the position sensor 52 is associated with the mounting portion of the shaft 16 on the first cooling plate 20. The power electronics 50 may be housed in different installation locations.

[0040] Figures 5 to 8.1 show various modified embodiments of the retaining member 36 in terms of both its geometric shape and cross-sectional configuration. Figure 5 shows a V-shaped embodiment of the retaining member 36, in which an embodiment of this retaining member 36 has a circular cross-section 56 made of solid material. This can be a plastic material, a metallic material, or a hybrid material, i.e., a combination of plastic and metallic materials, and applies to all embodiments of the retaining member 36 shown in Figures 5 to 8.1. This achieves a significant weight advantage, the noise, vibration, and harshness characteristics of the electromachine 10 proposed by the present invention are very well affected, and the mechanical stability of the electromachine components 12 and 14 of the electromachine 10 proposed by the present invention is not compromised.

[0041] Figure 6 shows a modified example of the W-shape 68 of the retaining member 36, in which the retaining member 36 has an annular cross-section 58. Figure 7 similarly shows an embodiment of the W-shape 68 of the retaining member 36, and according to Figure 7, a square cross-section 60 of a solid material may be realized, or a hollow profile 62 may be used as shown in Figure 7.2. In these embodiments of the retaining member 36, the retaining member 36 may be manufactured entirely from a metallic material, a plastic material, or a hybrid material of plastic and metallic material.

[0042] Figure 8 shows a modified example of the N-shape 70 of the retaining member 36, and the retaining member 36 in Figure 8.1 may have a V-shaped cross section 64. Instead of the V-shaped cross section 64, an I-shaped cross section may be selected. All retaining members 36 shown in Figures 5 to 8 may have modified cross sections of different shapes, as shown in Figures 5.1, 6.1, 7.1, 7.2 and 8.1. The formation of the cross section may be arbitrary. There are various base materials that can be used as retaining members 36. The cross-sectional geometries shown in Figures 5.1, 6.1, 7.1, 7.2 and 8.1 are given as examples.

[0043] Figures 9 and 9.1 show that the electromachine 10 proposed by the present invention, including a first electromachine member 12 and a second electromachine member 14, is connected to a vehicle chassis 80 of, for example, an electric-powered vehicle by a three-point bearing. The vehicle may not be a purely electric-powered vehicle but a hybrid vehicle (HEV, PHEV). Furthermore, the machine 10 proposed by the present invention may be used as a booster module or booster axle in the vehicle. The three-point bearing of the electromachine 10 proposed by the present invention is achieved by positioning damping members 82 between the connection points of the vehicle chassis 80. Bearings 84 are positioned in the form of a three-point bearing to the vehicle chassis 80 between the components of the electromachine 10, i.e., between the first cooling plate 20, the second cooling plate 22, and a further cooling plate 18 formed as a double cooling plate in this embodiment. Thus, the electromechanism 10 proposed by the present invention, which includes, for example, a first electromechanical member 12 and a second electromechanical member 14 formed in a cylindrical shape, is supported at three points on the vehicle chassis 80. The damping member 82 almost completely prevents noise or vibrations generated during operation from being transmitted to the vehicle chassis 80.

[0044] Figure 9.1 shows a front view of the electric machine 10 proposed by the present invention as shown in Figure 9. In Figure 9.1, the support points on the vehicle chassis 80 can be offset from each other by, for example, 180° and face each other. However, any angle other than 180° may be selected. An embodiment modification of Figure 9.1 also shows that the electric machine 10 proposed by the present invention includes a first cover 46 and a second cover 48 configured in a semi-shell shape, and these covers surround a first shielding half 42 and a second shielding half 44. Further components of the electric machine 10 proposed by the present invention as shown in Figures 9 and 9.1 are as already described in Figures 1, 1.1, 3 and 3.1.

[0045] Figures 10 and 10.1 show a modified embodiment in which the electromachine 10 proposed by the present invention is supported at three points on a vehicle chassis 80. Depending on the installation location of the electric axle module equipped with the electromachine 10 proposed by the present invention and the available installation space, it may be necessary to position a rod-shaped extension 86 between the chassis 80, the damping member 82, and the bearing 84. The extension 86 shown in Figure 10 corresponds to the bearing 84 on the first cooling plate 20. It is also possible to attach the rod-shaped extension 86 to the connection points to the vehicle chassis 80 for both bearings 84, i.e., the first cooling plate 20 and the second cooling plate 22. This is also shown in Figure 10.1, where, at the lower support point of the three-point support, the rod-shaped extension 86 extends between the corresponding damping member 82 on the lower surface 55 of the electromachine 10 proposed by the present invention and the bearing 84. The arrangement configuration of the rod-shaped or tubular extension 86 depends on the installation conditions or available installation space of the electromechanism 10 proposed by the present invention within the chassis 80 of the electric drive vehicle. In addition to electric drive vehicles, the electromechanism 10 proposed by the present invention may be used in hybrid vehicles (HEV, PHEV) or as a booster module or booster electric axle.

[0046] The components of the electrical machine 10 shown in Figures 10 and 10.1 are those already described in Figures 1, 1.1, 3, 3.1, 9, and 9.1. Figures 11 and 11.1 show embodiments of the electromachine 10 proposed by the present invention, in which a single-stage or multi-stage gear unit 90 is located on one outer surface of the cooling plates 20, 22. This is driven by a shaft 16 on the outer surface 54 of the first cooling plate 20. Alternatively, as shown in Figure 11, the single-stage or multi-stage gear unit 90 may be located on the outer surface 54 of the second cooling plate 22 of the second electromachine member 14. Figure 11.1 shows a side view of the arrangement configuration of the electromachine 10 proposed by the present invention according to Figure 11. Similar to the above embodiments of the electromachine 10 proposed by the present invention, the electromachine 10 has first and second covers 46, 48 which are shell-shaped, and these covers surround first and second shielding halves 42, 44 which are similarly shell-shaped.

[0047] The electromachine 10 proposed by the present invention may be formed, for example, as an axial flux machine. Instead of an axial flux machine, a hybrid radial-axial flux machine, as well as a transverse flux machine, is one possible variation.

[0048] All embodiments and modifications of the electromechanism 10 proposed by the present invention, as described with reference to Figures 1 to 11.1, share the common feature of significantly reducing material and weight by using a retaining member 36, and comprising either the first mechanical member 12 or either of the two electromechanical members 12 and 14. Furthermore, significantly more cost-effective manufacturing techniques can be used. By forming the retaining member 36 from a plastic material, not only are significant weight advantages achieved, but the noise, vibration, and harshness characteristics of the electromechanism 10 proposed by the present invention are significantly improved when mounted on a vehicle chassis 80. Noise radiation is significantly minimized, which is ensured by the fact that the electromechanism 10 proposed by the present invention, which is formed in a substantially cylindrical shape, is supported at three points. The internal components of the first electromechanical member 12 and the second electromechanical member 14 can be protected from the ingress of dust and water by covers 46, 48 and shielding halves 42, 44, but the interior of the electromechanism 10 can be freely accessed after removing the parts 42, 44 or 46, 48. Adjusting the distance, for example, readjusting the gap 40, can be done very easily by replacing the corresponding spacer member 38 at the connection point of the retaining member 36 to the cooling plates 18, 20, and 22.

[0049] The present invention is not limited to the embodiments or aspects emphasized herein. Rather, numerous modifications are possible within the scope of the claims, within the scope of expert practice.
