Description

Technical Field

[0001] This invention relates to an oil chamber sealing cover for a motor housing and a motor housing having such an oil chamber sealing cover. The invention also relates to a motor, particularly configured as a dual-motor system; and a motor vehicle having such a motor. Background Technology

[0002] There is a need to cool or regulate the temperature and lubricate the motor so that it can operate as efficiently as possible. In the automotive field, motors are used as drive units or traction units. Here, the design for efficient cooling and lubrication of the drive unit is associated with difficulties because the structural space of the components used for the cooling and / or lubrication cycle is limited by specified encapsulation boundary conditions. This, for example, results in only a very small volume of coolant / lubricant reservoir being housed within the drive motor housing, thus requiring additional coolant / lubricant reservoirs in other locations, as suggested, for example, in DE102020007635A1. To integrate the two reservoirs into the coolant / lubricant cycle, and especially to connect the two reservoirs to each other, it is necessary to install appropriate piping and / or hose mechanisms, combined with valve devices where necessary. However, this is particularly costly and requires additional structural space, thus further exacerbating the encapsulation problem. Furthermore, the current trend towards smaller drive motors makes it difficult to place interfaces for oil transfer between the oil reservoir and the housing (where the components to be regulated or lubricated are housed), and also makes ensuring the sealing of these interfaces challenging. Since threaded portions are often eliminated based on packaging boundary conditions, these threads allow axial sealing forces to be applied to the respective interfaces. Summary of the Invention

[0003] The objective of this invention is to achieve a cooling cycle that is particularly efficient in terms of structural space for electric motors, especially dual motors.

[0004] The task is addressed by the subject matter of the independent claims. Other possible solutions to the invention are disclosed in the dependent claims, the description, and the drawings. Features, advantages, and possible solutions set forth within the scope of the description for one of the subjects of the independent claims can be considered, at least similarly, as features, advantages, and possible solutions of the corresponding subjects of the other independent claims, as well as features, advantages, and possible solutions of any possible combination of the subjects of the independent claims (if necessary, combined with one or more dependent claims) in a cross-type and cross-implementation manner.

[0005] According to the present invention, an oil chamber sealing cover is proposed, which is disposed for a motor housing. Another proposed motor housing has an oil chamber sealing cover and an oil chamber housing portion. In a prescribed installation configuration, i.e., when the oil chamber sealing cover and the oil chamber housing portion are fixed to each other as prescribed, the housing has an oil chamber defined by the inner wall of the oil chamber housing portion and the oil chamber sealing cover. Furthermore, the present invention proposes a motor, particularly configured as a drive motor for a motor vehicle. According to a possible extension of the motor, the motor mechanism becomes a dual motor having two rotor-stator units arranged parallel to each other, the two rotor-stator units being individually controllable by means of a common control device for the motor. In the prescribed installation configuration, the motor forms part of a motor vehicle according to the present invention, which is also part of the present invention. Therefore, the motor vehicle relates to a motor vehicle capable of pure electric drive or hybrid drive.

[0006] The oil chamber sealing cover has a base having an outer side and an oil chamber side, which are opposite to each other and spaced apart by the thickness of the base. The oil chamber sealing cover is particularly planar in shape, wherein the extension dimensions along the longitudinal axis (x, see the coordinate system in the figures) and along the transverse axis (y) are dominant relative to the extension dimensions along the vertical axis (z). In the prescribed installation position, the oil chamber side faces the oil chamber or the oil chamber housing portion, while the outer side faces away from the oil chamber or the oil chamber housing portion. Additionally, the oil chamber sealing cover has one or more fixing holes, which are perpendicular, i.e., along the vertical axis (z), and completely penetrate the base. A channel mechanism is integrated into the base, having one or more channels, which are capable of allowing fluid, particularly oil, to flow through. The corresponding channel can be considered as a material-free area of ​​the oil chamber sealing cover, and in particular, without channel elements (pipes, hoses, etc.) manufactured separately from the substrate. Instead, the inner peripheral wall of the corresponding channel is made of the substrate material. The channel mechanism has a return oil channel that opens into the oil chamber boundary on the oil chamber side. Furthermore, the channel mechanism has a drain oil channel that opens into the oil chamber boundary on the oil chamber side. Two or more return oil channels and / or drain oil channels are conceivable. Additionally, the oil chamber sealing cover has one or more cantilever arms, with the respective cantilever arms and substrate material interlockingly connected. A cantilever channel fluidly connected to the return oil channel or drain oil channel is integrated in the respective cantilever arm, and a pipe fitting fluidly connected to the cantilever channel is provided at the distal end of the respective cantilever arm. In particular, the cantilever channel of one cantilever arm is connected to the drain oil channel, and the cantilever channel of the other cantilever arm is connected to the return oil channel. The pipe joint (i.e., its longitudinal central axis) extends parallel to the fixing hole from the outside toward the oil chamber side, that is, it extends parallel to the vertical axis (z) of the base.

[0007] In the case of the housing, the oil chamber closure cover and the oil chamber housing portion are tensioned together by a corresponding threaded element extending through one of the corresponding fixing holes. This threaded element has a bolt portion, and the head portion of the same threaded element connected to the bolt portion is tensioned to the outside of the base. The bolt portion is force-locked, form-locked, and / or material-locked connected to the oil chamber housing portion or the active component housing portion of the housing, for example, by screwing the bolt portion into a corresponding internal threaded hole, or by material-lockingly connecting the bolt portion and the oil chamber housing portion or the active component housing portion to each other, particularly as single-piece components. Depending on the situation, the bolt portion and the head portion can be material-locked to each other, particularly as single-piece components like screws, or manufactured separately. In the latter case, the head portion is screwed onto the bolt portion as a nut. Therefore, the housing has an oil chamber, which is defined by the inner wall of the oil chamber housing portion and a surface portion on the oil chamber side disposed within the oil chamber boundary. Pipe fittings are installed into corresponding pipe fittings in the active component housing, creating an arrangement that provides radial sealing for each pipe fitting. Alternatively, the pipe fittings of the active component housing and the oil chamber sealing cover can be mutually connected on their end sides, creating an arrangement that provides axial sealing for each pipe fitting. In particular, it is conceivable that the housing has not only a radially sealing pipe fitting arrangement but also an axially sealing pipe fitting arrangement. The active component housing has an active component chamber in the case of a motor, where the active components of the motor, i.e., one rotor and one stator or multiple rotors and multiple stators, are supported. The pipe fittings of the active component housing open into the active component chamber and allow fluid flow.

[0008] Due to one or more cantilevered arms of the oil chamber sealing cap, it is now possible, particularly effectively and considering the sealing boundary conditions, to achieve an oil transfer section that is oil-tight, without the need for adjacent threaded connections in the vicinity of the oil transfer section to establish and maintain a seal. This is because the pipe fitting of the oil chamber sealing cap is inserted into the pipe fitting of the active component housing portion during housing manufacturing, when the oil chamber is closed by means of the oil chamber sealing cap. Therefore, in areas where there are no threaded connections, the oil chamber can be closed by means of the geometry of the protruding cantilevered arms. The force necessary for the sealing effect between the pipe fittings is advantageously received in this case through the insertion connection of the pipe fittings. Although only the configuration of the pipe fittings is described here as such that the pipe fitting of the oil chamber sealing cap is inserted into the pipe fitting of the active component housing portion, the reverse configuration is of course equally desirable.

[0009] To achieve a particularly reliable sealing effect at the point where two pipe fittings intersect, i.e., in the case of a radially sealed pipe fitting arrangement, another possible embodiment of the housing specifies that a radial sealing element is provided between each pipe fitting, specifically between the outer peripheral wall of the pipe fitting in the oil chamber sealing cap and the inner peripheral wall of the pipe fitting in the active component housing portion. The radial sealing element is, for example, an annular sealing ring (also called an O-ring). For a particularly reliable sealing effect between the pipe fittings in an axially sealed pipe fitting arrangement, an annular disc-shaped axial sealing element clamped between the opposing ends of each pipe fitting can be provided.

[0010] According to another possible embodiment of the housing, a flat seal is clamped along the oil chamber boundary between the oil chamber side of the oil chamber closure cover and the end face of the oil chamber housing portion. In another possible embodiment of the oil chamber closure cover, the cover has a sealing groove formed along the oil chamber boundary on the oil chamber side, into which the flat seal can be fitted. Therefore, oil tightness between the oil chamber closure cover and the active component housing portion can be established and maintained particularly effectively. Lateral displacement of the flat seal is prevented because it abuts against the walls of the sealing grooves. In this relationship, the flat seal is clamped in the sealing groove in the case of the housing and thus clamped along the oil chamber boundary between the oil chamber side and the end face.

[0011] To manufacture the oil chamber sealing cap, one could consider providing a material plate and then milling a channel mechanism into it. This material plate and another material plate are then interconnected, such that the channel mechanism is fluid-tight except for its nozzle. A seal can be placed between the two material plates. Alternatively, the base, cantilever, and channel mechanism can be manufactured as single pieces. This can be achieved, for example, by manufacturing the base, cantilever, and channel mechanism using generative manufacturing methods, such as 3D printing, selective laser sintering, etc. Thus, the channel mechanism of the oil chamber sealing cap is specifically sealed, where the aforementioned seal is omitted.

[0012] Another possible implementation specifies that the substrate has a pressure pump connection device on its oil chamber side, which is fluidly connected to the oil drain channel, and the pressure side or suction side of the pressure oil pump can be fluidly connected to the pressure pump connection device. This means that the housing or the motor having the housing can have the pressure oil pump, the pressure side of which is fluidly connected to the oil drain channel. In this case, the suction side of the pressure oil pump is fluidly connected to or located in the oil chamber, such that the pressure oil pump draws oil from the oil chamber during its operation and pumps the oil out of the oil chamber via the oil drain channel. In particular, the pressure oil pump is thus completely or partially located in the oil chamber. Alternatively, the suction side of the pressure oil pump can be fluidly connected to the pressure pump connection device. The pressure side is then fluidly connected to the active component housing, while the suction side is fluidly connected to the oil drain channel. Therefore, the pressure oil pump draws oil from the oil chamber through the oil drain channel and pumps the oil into the active component housing during its operation. Here, the pressure oil pump is particularly located outside the oil chamber, for example, in the active component chamber or completely outside the housing.

[0013] As an alternative or supplement, the substrate has a suction pump connection device on its oil chamber side, which is fluidly connected to the return oil channel and allows fluid connection to the suction side of the suction pump. This means that the housing or the motor having the housing can have the suction pump, the suction side of which is fluidly connected to the return oil channel. The pressure side of the suction pump is connected to or disposed within the oil chamber. In particular, the suction pump is completely disposed within the oil chamber. This results in additional advantages in terms of the efficiency of the structural space and the encapsulation adaptability of the housing and therefore the motor, since the corresponding oil pump can be advantageously disposed directly within the oil chamber.

[0014] In a possible extension of the housing, the oil chamber housing portion is specified to have an oil supply channel fluidly connected to an oil discharge channel and opening onto the outer side of the oil chamber housing portion. Because the oil supply channel and the oil discharge channel are interconnected on the oil chamber side, it is permissible to connect the oil discharge channel to the oil circulation via the oil supply channel with particularly low cost. Because the oil chamber housing portion is on the outer side, and therefore the oil supply channel can be implemented particularly simply. The oil supply channel can terminate particularly laterally or curvedly outside the oil chamber housing portion, thus allowing oil transfer from the side of the oil chamber. Because the oil supply channel and the oil discharge channel are fluidly connected to each other via the oil chamber side when the oil chamber closure cover is fixed, such lateral deflection for oil can be established particularly simply and with low cost. Advantageously, it is possible to make the oil chamber closure cover move only in a straight installation direction.

[0015] Other features of the invention may arise from the claims, the drawings, and the description with reference to the drawings. Features and combinations of features mentioned above in the specification, as well as features and combinations of features shown separately in the description with reference to the drawings and / or in the drawings, may be applied not only in the correspondingly described combinations, but also in other combinations, or may be applied separately, without departing from the scope of the invention.

[0020] The oil chamber sealing cover 1 for the housing 2 of the motor 3, the housing 2, the motor 3, and the motor vehicle (not shown) having the motor 3 are explained in a common description. In the drawings, identical and functionally identical elements are given the same reference numerals. The longitudinal axis x, the transverse axis y, and the vertical axis z, or the corresponding spatial directions, are referred to below; the associated coordinate system is described in the drawings, which may, but does not necessarily, coincide with the coordinate system of the motor vehicle.

[0021] Figure 1 A perspective view of a motor 3 in a motor vehicle is shown, wherein the active components (rotor and stator) of the motor 3 are not illustrated. In the current example and as shown by... Figure 1 As can be seen, motor 3 is configured as a dual motor. This dual motor has two rotor-stator units arranged parallel to each other, which can be individually controlled by a common control device for the motors. The housing 2 of motor 3 has an oil chamber sealing cover 1, which... Figure 1 As can be seen in the image. Additionally, the housing 2 has an oil chamber housing portion 4 (in...). Figure 1 and Figure 2 Not visible in the middle, see also Figure 3 The housing 2 includes an active component housing portion 5. The active component housing portion 5 has an active component chamber 6, which has two sub-chambers 7 and 8, each supporting an active component assembly, which has a stator and a rotor. Currently, the housing 2 also has a central housing portion 9, in which a transmission, specifically one transmission for each active component assembly, is disposed.

[0022] Figure 2 Displayed from the perspective of direct observation of the oil chamber sealing cover 1 Figure 1 The perspective view of the motor 3 described herein shows that the oil chamber sealing cover has a base 10 with an outer side 11. Furthermore, the oil chamber sealing cover 1 has fixing holes 12, and in this embodiment, multiple fixing holes 12 are provided, each fixing hole 12 perpendicularly penetrating completely through the base 10.

[0023] Figure 3 A perspective view of the oil chamber sealing cover 1 is shown, with the oil chamber housing portion 4 of the housing 2 depicted transparently. The oil chamber sealing cover 1 has an oil chamber side 13 opposite to the outer side 11 and spaced apart from it by the thickness of the base 10. A channel mechanism (not shown) is integrated in the base 10, the return oil passage of which opens into the oil chamber boundary 14 on the oil chamber side 13, and the drain oil passage of which opens into the oil chamber boundary 14 on the oil chamber side 13. Furthermore... Figure 3 As can be seen, the oil chamber sealing cover 1 has a laterally extending geometry, in that it has cantilever 15, in this embodiment having two or more cantilever 15s, each cantilever 15 being materially locked to the base 10. Here, the cantilever 15 extends from the base 10, for example in or along the xy plane of the oil chamber sealing cover 1. Some embodiments of the oil chamber sealing cover 1 are conceivable in which the cantilever 15, or one or more of the cantilever 15s, extends from the base 10 obliquely and / or parallel to the vertical direction z. In each cantilever 15, a cantilever channel (not shown) fluidly connected to the return oil channel is integrated, and a pipe joint 17 fluidly connected to the cantilever channel is provided on the distal end 16 of the respective cantilever 15. The pipe joint 17 extends parallel to the corresponding fixing hole 12 from the outer side 11 toward the oil chamber side 13, i.e., parallel to the vertical axis z of the base 10. The substrate 10, one or more cantilever arms 15, and channel mechanisms and corresponding cantilever channels are constructed monolithically according to the present embodiment, for example by means of selective laser sintering. Additionally, the corresponding cantilever arms 15 and associated pipe fittings 17 can be constructed monolithically. However, it is also preferable that the pipe fittings 17 and cantilever arms 15 are first manufactured separately and then connected to each other by force-locking, form-locking, and / or material-locking. For example, the pipe fitting 17 may have external threads and can be screwed into a corresponding internal threaded hole provided on the end 16 of the cantilever arm 15.

[0024] exist Figure 3 As can also be seen, a sealing groove 18 is formed along the oil chamber boundary 14 on the oil chamber side 13 of the substrate 10, and a flat seal (not shown) is fitted into this sealing groove. (See also...) Figure 3 and Figure 2 As can be seen, in the prescribed installation configuration, the oil chamber side 13 faces the housing 2, and the oil chamber housing portion 4 and the oil chamber sealing cover 1 are tensioned together by means of threaded elements (not shown), currently by means of multiple threaded elements. The corresponding threaded elements extend through the corresponding fixing holes in each fixing hole 12, with the head portion of the corresponding threaded element abutting against the outer side 11 of the base 10. In this manner, the base 10 is clamped between the head portion of the threaded element and the end face of the oil chamber housing portion 4, and a flat seal is inserted into the sealing groove 18 between the oil chamber side 13 of the base 10 and the end face of the oil chamber housing portion 4. Here, the end edge of the oil chamber housing portion 4 can be partially embedded in the sealing groove 18. Therefore, the housing 2 has an oil chamber 19, which is defined by the inner wall 20 of the oil chamber housing portion 4 and the surface portion 21 of the oil chamber side 13 disposed within the oil chamber boundary 14. Additionally, the corresponding pipe joint 17 of the cantilever 14 is installed into the corresponding pipe joint 22 of the active component housing 5, which leads into the active component chamber 6, i.e., into one or two sub-chambers 7 and 8.

[0025] This method allows for a particularly simple establishment of oil tightness between pipe joints 17 and 22, as the force required for the sealing effect between pipe joints 17 and 22 is received through the insertion connection of pipe joints 17 and 22. An inverted configuration is also desirable, in which pipe joint 22 of the active component housing portion 5 is inserted into pipe joint 17 of the cantilever 15. A radial sealing element 23, in its current form a sealing ring, is provided between each pipe joint 17 and 22, i.e., between the outer peripheral wall of the oil chamber sealing cap 1 or the pipe joint 17 of the cantilever 15 and the inner peripheral wall of the pipe joint 22 of the active component housing portion 5.

[0026] Therefore, in some areas (where there are no locations for threaded connections to apply a sealing force acting along the vertical axis z), the oil chamber 19 can be closed by means of the geometry of the protruding cantilever 15. Figure 3 In the description, another cantilever 24 is shown, which has no pipe joint at its distal end 25. To achieve oil tightness here, an axial sealing element 26 is placed between the cantilever 24 and the associated pipe joint 22 of the active component housing portion 5. The axial sealing element 26 is then axially clamped between the cantilever 15 and the pipe joint 22 by means of a threaded connection 27 disposed in the adjacent area. (As in...) Figure 3 As can be seen, the sealing effect of the axial sealing element 26 may be affected because these threaded connection devices 27, for example due to encapsulation reasons, cannot work together with the base 10 or the oil chamber closure cover 1.

[0027] In the current specification, the base 10 has a pressure pump connection device on its oil chamber side 13, which is fluidly connected to the oil drain channel and fluidly connected to the pressure side of the pressure oil pump 28.

[0028] The suction side of the pressure oil pump 28 is connected to or disposed within the oil chamber 19. While it is conceivable that the oil return to the oil chamber 19 could be achieved solely by gravity, according to the current embodiment, the base 10 has a suction pump connection device on its oil chamber side 13, which is fluidly connected to the return oil passage and to the suction side of the suction pump 29. The pressure side of the suction pump 29 is connected to or disposed within the oil chamber 19. (As per...) Figure 3 As can be seen, in the current embodiment, the two oil pumps 28 and 29 are completely disposed in the oil chamber 19.

[0029] In this embodiment, it is further specified that the oil chamber housing portion 4 has an oil supply channel 30, which is fluidly connected to the oil discharge channel and extends into the outer side 31 of the oil chamber housing portion 4. (See also...) Figure 3 As can be seen, the oil supply passage 30 ends on the side or in a curved manner. Because the oil supply passage 30 and the oil drain passage are interconnected on the oil chamber side 13, it is possible to connect the oil drain passage to the oil circulation via the oil supply passage 30 with particularly low consumption. Because the oil supply passage 30 and the oil drain passage are fluidly connected to each other on the oil chamber side 13 when the oil chamber sealing cover 1 is fixed, the oil chamber sealing cover 1 can move only in a straight installation direction in order to fix the oil chamber sealing cover to the oil chamber housing part 4, wherein a direct flange connection is achieved between the oil supply passage 30 and the oil drain passage.

[0030] The oil chamber sealing cover 1, housing 2, motor 3, and motor vehicle demonstrate the corresponding possibilities: how to achieve a cooling cycle that is particularly efficient in terms of structural space for the motor, especially for dual motors 3.
