Description

Technical Field

[0001] This invention relates to a rotor support device for a rotor of an electric motor used in a plate clutch, the rotor support device having a rotor bracket and a plate bracket rotatably connected to the rotor bracket, the rotor bracket having a tubular rotor support section extending in an axial direction for securing the rotor, and the plate bracket having a substantially tubular plate support section for the plates, the plate support section having a rotatable profile, wherein the rotor bracket and the plate bracket are fastened to each other via at least one first fastening mechanism. The invention also relates to a combination of a plate clutch and an electric motor having such a rotor support device. Background Technology

[0002] A combination of a plate clutch and an electric motor is known from DE 10 2014 014 236 A1. The plate clutch has a plate carrier with a generally tubular plate support section, on which a rotational drive profile for the outer plates is provided. The plate support section also serves as a rotor support section, in which the rotor of the electric motor is secured to the radially outward side of the plate support section. Since the plate carrier thus also constitutes a rotor carrier, a particularly compact structure can be achieved; however, securing the rotor firmly to the outside of the plate support section requires particularly precise manufacturing of the plate support section.

[0003] DE 10 2016 013 417 A1 also describes a combination of a plate clutch and an electric motor. Thus, the plate clutch has a plate carrier with a generally tubular plate support section having a rotational drive profile for the outer plates, and a support section adjacent to the tubular plate support section for radially supporting the plate support section. Furthermore, a rotor carrier is provided for supporting the rotor. The rotor carrier has an axially extending tubular rotor support section for securing the rotor, and a securing section extending radially from the rotor support section, wherein the securing section is secured to the support section of the plate carrier of the plate clutch via a securing mechanism to achieve rotational drive. The rotor support section of the rotor carrier is axially spaced outward from the plate support section of the plate carrier. Compared to the prior art described above, this adds a further component, namely the rotor bracket, but in this way the rotor bracket and the ladle bracket can be precisely matched to their intended tasks without any interaction, just as this might be the case in the prior art described above.

[0004] The last piece of prior art, namely the rotor support device for the rotor of the electric motor used in a plate clutch, has proven itself, but further improvements are needed in terms of achieving greater rigidity of the rotor support device for improved operational smoothness and, where necessary, improved cooling, especially in the case of a wet plate clutch. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a rotor support device for the rotor of an electric motor used in a plate clutch, which has higher rigidity, thus providing improved operational smoothness, and ensuring improved cooling of the plate clutch and / or the electric motor if necessary. Furthermore, the object of the present invention is to provide a combination of a plate clutch and an electric motor having this type of advantageous rotor support device.

[0006] The objective is achieved by the features specified in claim 1 or 10. Advantageous embodiments of the invention are the subject of the dependent claims.

[0007] The rotor support device according to the invention is designed to support a rotor for use in a plate clutch or for use in a combination of a plate clutch and a motor. The rotor support device has a rotor bracket. The rotor bracket has a tubular rotor support section extending axially for securing the rotor of the motor. The tubular rotor support section is preferably constructed as a cylinder or has a circular shape in the front view. Furthermore, it is preferred that the tubular rotor support section has a tight fit for the interior of an annular rotor on its radially outwardly pointing side. Additionally, the rotor support device has a plate bracket that is rotatably connected to the rotor bracket. The plate bracket has a substantially tubular plate support section with a rotatable profile for the plates of the plate clutch. The tubular plate support section also preferably extends axially. The rotor bracket and the plate bracket are fastened to each other via at least one first fastening mechanism to achieve a rotatable connection at least between the rotor bracket and the plate bracket. Preferably, the plate bracket and the rotor bracket are also fixed to each other in the axial and / or radial directions via at least one first fastening mechanism. The plate support and rotor support are preferably directly adjacent to each other. Multiple first fastening mechanisms can be provided, for example, following each other in the circumferential direction and / or spaced apart from each other in the aforementioned circumferential direction. The first fastening mechanisms can be, for example, riveted connections, threaded connections, or welded connections. To achieve particularly high rigidity of the rotor support assembly and thus improved operational smoothness, the rotor support and plate support are fastened to each other via at least one second fastening mechanism spaced apart from the first fastening mechanisms in the axial direction, wherein the at least one second fastening mechanism can again be, for example, a riveted connection, threaded connection, or welded connection. Multiple second fastening mechanisms can also be provided again, which are again spaced apart from each other in the circumferential direction and / or may follow each other. At least the second fastening mechanism is preferably configured such that the rotor support and plate support are also rotatably connected to each other via this second fastening mechanism and are particularly preferably fixed to each other in the axial and / or radial directions. Furthermore, the plate support and rotor support are also preferably directly adjacent to each other. Compared to DE 10 2016 013 417 A1, it has been shown that, due to the second fastening mechanism, end-side widening in the open region of the plate support section can be prevented more reliably at high speeds, without the need for further auxiliary devices or a particularly thick-walled plate support section. Furthermore, due to the second fastening mechanism, a relatively thin-walled rotor support section can be used without the risk of end-side widening at high speeds, thereby at least partially reducing the distance between the rotor and stator of the motor. It can thus be determined that the reliable functioning of both the plate clutch and the motor is ensured by the second fastening mechanism, which is spaced apart from the first fastening mechanism in the axial direction.

[0008] In a preferred embodiment of the rotor support device according to the invention, the rotor bracket has a support section extending radially for supporting the rotor bracket in the radial direction. The support section is preferably constructed as a single piece with the rotor support section. In this embodiment, it is also preferred that the lamination bracket is indirectly supported or supported in the radial direction via the support section of the rotor bracket. Thus, the support section of the rotor bracket also provides support for the lamination bracket or its lamination support section in the radial direction, thereby achieving a lightweight and compact structure. This is particularly preferred because maintaining a constant clearance between the rotor of one motor and the stator of the other motor ensures reliable and precise support for the rotor bracket along with its rotor support section. However, in an alternative embodiment variant, the lamination bracket has a support section extending radially for supporting the lamination support section in the radial direction, wherein in this case, the rotor bracket or its rotor support section is indirectly supported or supported in the radial direction via the support section of the lamination bracket, in order to achieve a compact and simple structure.

[0009] In an advantageous embodiment of the rotor support device according to the invention, the rotor bracket or plate bracket has the aforementioned support section, which can be supported or supported in the radial direction via a support hub constructed or fastened to the support section.

[0010] In a particularly preferred embodiment of the rotor support device according to the invention, the rotor bracket has the aforementioned support section, and the lamination bracket has a first fastening section extending radially, which is fastened to the rotor bracket by a first fastening mechanism, preferably to the support section of the rotor bracket. Thus, the first fastening section extending radially can very simply and securely fasten the lamination bracket and the rotor bracket to each other via the first fastening mechanism, which not only simplifies production but also enables robust support between the components. Alternatively, the rotor bracket has a first fastening section extending radially, and if the aforementioned support section is constructed as part of the lamination bracket, this first fastening section is fastened to the lamination bracket by the first fastening mechanism, preferably to the support section of the lamination bracket.

[0011] If the aforementioned support section is constructed as part of the rotor bracket, then in another advantageous embodiment of the rotor support device according to the invention, the lamellar bracket has a second fastening section extending radially, which is fastened to the rotor bracket by a second fastening mechanism, preferably to a radially extending section of the rotor bracket. Particularly preferred here is that the radial section follows the end of the rotor support section opposite to the support section. In an alternative embodiment variant where the lamellar bracket includes the aforementioned support section, the rotor bracket has a second fastening section extending radially, which is fastened to the lamellar bracket by a second fastening mechanism, preferably to a radially extending section of the lamellar bracket. Particularly preferred here is that the radial section follows the end of the lamellar support section opposite to the support section. Furthermore, in both mentioned embodiment variants, it is preferred that the radial section is constructed as a single piece with the rotor support section or the lamellar support section. Furthermore, it has been shown that in both embodiment variations, it is advantageous for the second fastening section to follow the end of the plate support section or rotor support section away from the first fastening section and to be constructed as a single piece with the plate support section or rotor support section.

[0012] In another advantageous embodiment of the rotor support device according to the invention, if the support section and the radial section are constructed as part of the rotor bracket, the support section and the radial section protrude beyond the rotor support section in opposite radial directions; or if the support section and the radial section are constructed as part of the lamination bracket, the support section and the radial section protrude beyond the lamination support section in opposite radial directions. In this way, a rotor bracket or lamination bracket can be manufactured in a particularly simple manner, for example, by sheet metal forming and / or deep drawing.

[0013] In another advantageous embodiment of the rotor support device according to the invention, the first and second fastening sections protrude beyond the plate support section in opposite radial directions when the plate bracket has the first and second fastening sections, or protrude beyond the rotor support section when the rotor bracket has the first and second fastening sections, so as to enable particularly simple manufacturing of the plate bracket or the rotor bracket, respectively.

[0014] In a particularly preferred embodiment of the rotor support device according to the invention, the rotor bracket has a substantially tubular second support section having a rotational drive profile for the plates. Preferably, the second support section follows the end of the radial section or the second fastening section opposite to the rotor support section. Alternatively, the plate bracket has a substantially tubular second support section having a rotational drive profile for the plates, wherein the second support section preferably follows the end of the second fastening section or the radial section of the plate bracket opposite to the plate support section. Functional expansion is achieved through variations of the two embodiments described above, namely, extending the rotor bracket function to another plate bracket, or extending the plate bracket function to a double-plate bracket for a double-plate clutch. In both cases mentioned, the second support section preferably has a larger or smaller diameter than the rotor support section or the first support section. It is also preferred that the second support section of the rotor bracket is integrally constructed with the other sections of the rotor bracket, or that the second support section of the plate bracket is integrally constructed with the other sections of the plate bracket.

[0015] To achieve a particularly small axial structural length for the rotor support device, in another preferred embodiment of the rotor support device according to the invention, the rotor support section and the lamellar support section are nested in the radial direction, so that the radial nesting of the rotor and lamellars is also achieved in the same installation state within the transmission system. It is also advantageous in this embodiment that the rotor support section radially surrounds the lamellar support section from the outside.

[0016] In another advantageous embodiment of the rotor support device according to the invention, the rotor support section and the plate support section are also constructed or supported abutting each other in the radial direction when arranged in a radially nested manner, so as to achieve a particularly compact structure in the radial direction in this region.

[0017] According to another particularly advantageous embodiment of the rotor support device according to the invention, an annular space is formed radially between the rotor support sections and plate support sections nested together in the radial direction, and encircling circumferentially. This annular space can advantageously be used to temporarily block and distribute cooling fluid within the wet plate clutch to improve or specifically control cooling. Preferably, at least one fluid passage opening for establishing a flow connection with the annular space is provided in the rotor support section and / or the plate support section. Thus, the fluid passage opening in the rotor support section can establish a flow connection between the annular space and the region of the rotor, while the fluid passage opening in the plate support section can be used to establish a flow connection between the region of the plate and the annular space.

[0018] In another preferred embodiment of the rotor support device according to the invention, at least one first fluid channel opening and one second fluid channel opening spaced apart from each other in the axial direction are provided in the rotor support section. If such cooling of the rotor is desired, then, with a suitable interval, cooling fluid can thus flow from the annular space across both sides of the rotor fastened to the rotor support section between the first and second fluid channel openings.

[0019] According to another advantageous embodiment of the rotor support device according to the invention, the annular space is defined in two axial directions, which is achieved by a support section and / or a first fastening section and / or a second fastening section. Here, in order to enable further distribution of the cooling fluid disposed in the annular space, it is also preferred in this embodiment that at least one fluid passage opening for establishing a flow connection with the annular space is provided in the support section and / or the first fastening section and / or the second fastening section. In this way, the fluid, at least partially retained in the annular space, can flow out of the annular space in at least one of two opposing axial directions and thus be metered and selectively distributed.

[0020] In another advantageous embodiment of the rotor support device according to the invention, the first and second fastening mechanisms are constructed separately from each other. The first and second fastening mechanisms are also constructed here to be spaced apart from each other.

[0021] According to another advantageous embodiment of the rotor support device according to the invention, the first and / or second fastening mechanism is constructed as a riveted connection, a threaded connection, or a welded connection.

[0022] As described above, the rotor bracket and the plate bracket are fastened to each other via first and second fastening mechanisms. However, in another preferred embodiment of the rotor support device according to the invention, the rotor bracket and the plate bracket are constructed separately from each other and therefore not as a single piece. More precisely, the rotor bracket and the plate bracket are initially manufactured separately from each other before they are fastened to each other via the fastening mechanisms.

[0023] In another advantageous embodiment of the rotor support device according to the invention, the rotor bracket is constructed as a single piece. In other words, the aforementioned possible sections of the rotor bracket are constructed as a single piece together with the rotor support section.

[0024] In another advantageous embodiment of the rotor support device according to the invention, the lamellar support is constructed as a single piece. In other words, the aforementioned possible sections of the lamellar support are constructed together as a single piece with the lamellar support section.

[0025] In order to achieve a particularly compact structure of the rotor support device in the axial direction, the rotor support section and / or plate support section extend at least 80%, preferably at least 90%, and particularly preferably completely between the first and second fastening mechanisms relative to the axial direction in another particularly advantageous embodiment of the rotor support device according to the invention.

[0026] According to another advantageous embodiment of the rotor support device according to the invention, the rotor support device includes a rotor of an electric motor, wherein the rotor is fastened to a rotor support section. Preferably, the rotor is pushed onto the rotor support section and / or fastened to the rotor support section by press fitting. The aforementioned fastening of the rotor to the rotor support section preferably includes, in addition to the necessary fixation of the rotor in the circumferential direction to the rotor support section, also the fixation of the rotor in the axial direction to the rotor support section.

[0027] According to another preferred embodiment of the rotor support device with a rotor according to the invention, the aforementioned first fluid channel opening in the rotor support section opens into a first region in the axial direction in front of the rotor, and the aforementioned second fluid channel opening opens into a region in the same axial direction behind the rotor. This ensures the previously indicated flow around the rotor via the first and second fluid channel openings.

[0028] The present invention also relates to a plate clutch, preferably a double-plate clutch, and a combination thereof, particularly preferably, an electric motor in the transmission system of a motor vehicle. The combination of the plate clutch and the electric motor has the aforementioned embodiment of the rotor support device according to the invention. Attached Figure Description

[0029] The invention will now be explained in more detail with reference to the accompanying drawings and exemplary embodiments. In the drawings:

[0030] Figure 1 A partial side view of a combination of a plate clutch and an electric motor with a rotor support device shown in sectional view of a first embodiment is shown.

[0031] Figure 2 It shows Figure 1 Details of the second embodiment of the rotor support device;

[0032] Figure 3 It shows Figure 1 Details of the third embodiment of the rotor support device;

[0033] Figure 4 It shows Figure 1 Details of the fourth embodiment of the rotor support device;

[0034] Figure 5 It shows Figure 1Details of the fifth embodiment of the rotor support device; and

[0035] Figure 6 It shows Figure 1 Details of the sixth embodiment of the rotor support device. Detailed Implementation

[0036] Figure 1 The combination of a plate clutch 2 and an electric motor 4 is shown at least partially, wherein the combination has a first embodiment of a rotor support device 6. Figure 1 And in the following figures, the opposing axial directions 8, 10, opposing radial directions 12, 14, and opposing circumferential directions 16, 18 of the combined or rotor support device are indicated by corresponding arrows, wherein the combined or rotor support device 6 is configured to be rotatable about the rotation axis 20 in the circumferential directions 16, 18. Although in Figure 1 Only one plate group of the plate clutch 2 is shown in the figure, but the plate clutch 2 is preferably a double plate clutch with at least two plate groups.

[0037] Rotor support device 6 is designed to support rotor 22 of electric motor 4 used in plate clutch 2, wherein... Figure 1 Only the rotor 22 of the motor 4 is shown, which is annularly constructed and externally surrounded by the stator of the motor 4 (not shown further) in the radial direction 12. The rotor support assembly 6 is mainly assembled from the lamellar bracket 24 and the rotor bracket 26, which are rotatably connected to each other. The lamellar bracket 24 and the rotor bracket 26 are also connected to each other such that they are fixed to each other in the radial directions 12, 14 and the axial directions 8, 10.

[0038] The plate holder 24, configured as an outer plate holder 24, has a substantially tubular plate support section 28 extending in opposite axial directions 8, 10. The plate support section 28 has a rotational drive profile 30 pointing inward in the radial direction 14 to achieve rotational drive connection with the plate 32 of the plate clutch 2, wherein the plate 32 is movable relative to the plate holder 24 in the axial directions 8, 10. Furthermore, in Figure 1 The diagram shows another plate holder 34 of the plate clutch 2, which is rotatably connected to a mating plate 36 disposed on the plate 32. In the illustrated embodiment, the plate holder 34 constitutes, for example, the input side of the plate clutch 2, while the additional plate holder 34 constitutes at least one output side of the plate clutch 2.

[0039] The sheet support 24, constructed as a sheet metal part or a sheet-formed part, has a first fastening section 38 in addition to the sheet support section 28. The first fastening section 38 follows the sheet support section 28 in the axial direction 8 and extends substantially inward in the radial direction 14 from the sheet support section 28, such that the first fastening section 38 has an annular sheet shape. Therefore, the first fastening section 38 extends inward in the radial direction 14 to the end identified by reference numeral 40. Furthermore, the sheet support 24 has a second fastening section 42. The second fastening section 42 abuts the sheet support section 28 in the opposite axial direction 10 so as to extend outward in the radial direction 12 from the sheet support section 28. Therefore, the second fastening section 42 is also substantially constructed in an annular sheet shape, wherein it extends radially in the radial direction 12 to its end 44. Therefore, it can be seen that the second fastening section 42 follows the end of the sheet support section 28 opposite to the first fastening section 38, wherein the first fastening section 38 and the second fastening section 42 protrude beyond the sheet support section 28 along opposite radial directions 14 and 12. The sheet bracket 24 is also constructed as a single piece, thus it is formed from a single sheet metal piece and the sheet support section 28, the first fastening section 38 and the second fastening section 42 are constructed as a single piece to each other.

[0040] The rotor bracket 26 is constructed as a one-piece sheet metal part or a sheet metal molded part. The rotor bracket thus has a tubular rotor support section 46 extending in the axial directions 8, 10, for securing the rotor 22 of the motor 4. Compared to the tubular sheet support section 28 having a rotational drive profile 30, the rotor support section 46 is constructed to be substantially cylindrical. The rotor support section 46 thus has an outer side 48 pointing outward in the radial direction 12 and an inner side 50 pointing inward in the radial direction 14. The outer side 48 of the rotor support section 46 is constructed to fit tightly with the rotor 22, which is pushed or pressed onto the rotor support section 46 in the axial direction 10 by a press fit between the outer side 48 and the inward-facing side of the rotor 22 in the radial direction 14. In this way, a rotational drive connection is established between the rotor bracket 26 and the rotor 22, which is further secured to the rotor support section 46 in the axial directions 8, 10 by a press fit or by means of further fastening devices.

[0041] The rotor bracket 26 also has a support section 52 for supporting the rotor support section 46 in the radial directions 12, 14. In the illustrated embodiment, the support section 52 is adjacent to the rotor support section 46 in the axial direction 8 so as to extend inwardly in the radial direction 14 from the rotor support section 46. The support section 52, which is constructed as a single piece with the rotor support section 46, can therefore also be referred to as a substantially annular plate-shaped support section 52. The support section 52 is guided inwardly in the radial direction 14 to the support hub 54. The support hub 54 can here be formed on the support section 52 and thus constructed as a single piece with or fastened to the support section, such as Figure 1 As shown. In any case, the radial support of the rotor support section 46 is provided via the support section 52 and the support hub 54. In the illustrated embodiment, the support hub 54 may be supported or be supported on a member 58 of a fixed or rotatable, preferably fixed, support tube, for example via two radial bearings 56, preferably roller bearings.

[0042] Furthermore, the rotor bracket 26 has a radial section 60, which is also constructed as a single piece with the rotor support section 46, following the rotor support section 46 in the axial direction 10. The radial section 60 extends outward from the rotor support section 46 in the radial direction 12 to an end 62, and can therefore also be referred to as a substantially annular plate-shaped radial section 60. As can also be seen from the foregoing description, the radial section 60 thus follows the end of the rotor support section 46 opposite to the support section 52. The support section 52 and the radial section 60 also protrude beyond the rotor support section 46 of the rotor bracket 26 in opposite radial directions 14 and 12.

[0043] As described above, the plate bracket 24, together with the plate support section 28, the first fastening section 38, and the second fastening section 42, is formed from a single sheet metal piece, and the rotor bracket 26, together with the rotor support section 46, the support section 52, the radial section 60, and, if necessary, the support hub 54, is also formed from a single sheet metal piece. Here, the rotor bracket 26 and the plate bracket 24 are manufactured separately before they are fastened together by achieving the aforementioned rotational connection; therefore, it can be said that the rotor bracket 26 and the plate bracket 24 are constructed separately and are not constructed as a single piece. To achieve the rotational connection between the plate bracket 24 and the rotor bracket 26, they are fastened together via at least one first fastening mechanism 64 and additionally via at least one second fastening mechanism 66 spaced apart from the first fastening mechanism 64 in the axial directions 8, 10. Figure 1It can be seen that the first fastening section 38 of the plate bracket 24 is fastened to the rotor bracket 26 via or through the first fastening mechanism 64, more precisely, to the support section 52 of the rotor bracket 26, wherein the plate bracket 24 and the rotor bracket 26 are also directly adjacent to each other. On the other hand, the second fastening section 42 of the plate bracket 64 is fastened to the rotor bracket 26 via or through the second fastening mechanism 66, more precisely, to the radial section 60 of the rotor bracket 26 extending in the radial direction, wherein the plate bracket 24 and the rotor bracket 26 are also directly adjacent to each other. Here, the side of the first fastening section 38 pointing in the axial direction 8 is preferably supported on the side of the support section 52 pointing in the axial direction 10, while the side of the second fastening section 42 pointing in the axial direction 8 is preferably supported on the side of the radial section 60 pointing in the axial direction 10. Figure 1 It can also be seen that the support section 52 extends beyond the end 40 of the first fastening section 38 in the radial direction 14 so as to support the rotor support section 46 in the radial directions 12, 14 via the support hub 54, so that the plate bracket 24 or its plate support section 28 can be indirectly supported or supported in the radial directions 12, 14 via the support section 52 of the rotor bracket 26 and via the support hub 54.

[0044] In the accompanying drawings, both the first fastening mechanism 64 and the second fastening mechanism 66 are exemplarily and advantageously shown or designed as welded connections. This welded connection can be a single first or second fastening mechanism 64 or 66, configured as a weld encircling the circumferential directions 16, 18. However, similarly, multiple first or second fastening mechanisms 64 or 66 can be provided, each consisting of weld points or weld positions spaced apart along the circumferential directions 16, 18. Although not shown, the fastening mechanisms 64, 66 can also be configured as riveted or threaded connections. Regardless of the connection type selected for each fastening mechanism 64, 66, they achieve, on the one hand, a rotational drive connection between the plate bracket 24 and the rotor bracket 26, and on the other hand, preferably, a fixation between the plate bracket 24 and the rotor bracket 26 in the axial directions 8, 10 and / or the radial directions 12, 14. At least one first fastening mechanism 64 and at least one second fastening mechanism 66 are also constructed separately from or spaced apart from each other, i.e., the first fastening mechanism 64 and the second fastening mechanism 66 are not constituted by a common weld, a common threaded connection or a common rivet connection.

[0045] The rotor support section 46 and the lamellar support section 28 are also configured to be nested in the radial directions 12, 14. More precisely, the rotor support section 46 surrounds the lamellar support section 28 from the outside in the radial direction 12, wherein the rotor support section 46 and the lamellar support section 28 are nested according to... Figure 1In this embodiment, they are constructed or supported abutting each other in the radial directions 12 and 14. More precisely, the outer side 68 of the plate support section 28 in the radial direction 12 at least partially abuts or supports the inner side 50 of the rotor support section 46 in the radial direction 12. This is according to Figure 1 The fact that the illustrated embodiment represents only a partial case is based on the fact that the sheet support section 28 has a molded rotational driving profile 30 and therefore lacks a continuous cylindrical side surface 68. Furthermore, in Figure 1 In this configuration, the rotor support section 46 and / or the plate support section 28 extend at least partially between the first fastening mechanism 64 and the second fastening mechanism 66 with respect to the axial extension directions 8 and 10. Preferably, in this configuration, the rotor support section 46 and / or the plate support section 28 extend with respect to the axial directions 8 and 10 to at least 80%, preferably at least 90%, and particularly preferably entirely between the first and second fastening mechanisms 64 and 66.

[0046] Figure 2 A second embodiment of the rotor support device 6 is shown. Figure 1 The details are essentially the same as those of the first embodiment, wherein only the differences are discussed below, the same or similar parts are referred to by the same reference numerals, and the foregoing description applies accordingly in other respects.

[0047] According to Figure 2In the second embodiment, the plate support section 28 and the rotor support section 46 are still nested in the radial directions 12, 14, but an annular space 70 is constructed in the radial directions 12, 14 between the rotor support section 46 and the plate support section 28, which can also be described as a closed space surrounding in the circumferential directions 16, 18. Since the plate clutch 2 is preferably a wet plate clutch, the cooling fluid and / or lubricating fluid can be advantageously guided and stored in this way, thereby improving or more specifically cooling the plate clutch 2 and, if necessary, the rotor 22 of the motor 4. Therefore, at least one fluid passage opening 72 is constructed in the plate support section 28 to establish a flow connection with the annular space 70. In other words, fluid can flow outward from the region of the plate assemblies 32, 36 in the radial direction 12 into the annular space 70. At least one fluid channel opening is also provided in the rotor support section 46, allowing fluid within the annular space 70 to reach the region of the rotor 22 radially outward via the fluid channel opening 12. More precisely, at least one first fluid channel opening 74 and at least one second fluid channel opening 76 are constructed or provided in the rotor support section 46, spaced apart from the first fluid channel opening 74 in the axial direction 10. Here, the first fluid channel opening 74 and the second fluid channel opening 76 are spaced apart from each other, such that the first fluid channel opening 74 leads to a first region in the axial direction 10 in front of the rotor of the motor 4, which is fastened to the rotor support section 28, and the second fluid channel opening 76 leads to a second region in the same axial direction 10 in the axial direction 10 behind the rotor of the motor 4, which is fastened to the rotor support section 28. In this way, the rotor 22 can be cooled or lubricated on both sides in the axial direction by fluid passing through the annular space via the fluid channel openings 74 and 76.

[0048] Figure 3 A third embodiment of the rotor support device 6 is shown, which substantially corresponds to the embodiment according to... Figure 2 The second embodiment is described below only for the differences, the same reference numerals apply to the same or similar parts, and the foregoing description applies accordingly in other respects.

[0049] As in accordance with Figure 2 As shown in the second embodiment, in accordance with Figure 3In the third embodiment, the annular space 70 is also defined in two axial directions 8 and 10. Specifically, the annular space 70 is defined in axial direction 8 by a support section 52 and in axial direction 10 by a second fastening section 42. Nevertheless, in order to distribute fluid within the annular space 70 along axial directions 8 and / or axial directions 10, at least one fluid channel opening 78 is constructed in the support section 52 and at least one fluid channel opening 80 is constructed in the second fastening section 42, via which a flow connection with the annular space 70 is established along axial directions 8 and 10. Figure 3 It can also be seen that, in the third embodiment, the aforementioned at least one first fluid passage opening 74 and at least one second fluid passage opening 76, more precisely, generally the fluid passage openings within the rotor support section 46, are omitted. This is advantageous, for example, when the rotor should not be cooled or lubricated by lubricating fluid, or is only cooled or lubricated to a limited extent. However, it should be noted that, according to... Figure 3 In the third embodiment, at least one of the first or second fluid channel openings 74 and 76 may also be provided.

[0050] Figure 4 A fourth embodiment of the rotor support device 6 is shown, which substantially corresponds to the embodiment according to... Figure 2 The embodiments of or / and 3 are described below only, and the same reference numerals apply to the same or similar parts, and the foregoing description applies accordingly in other respects.

[0051] In the fourth embodiment, the radial section 46 of the rotor carrier 26 lacks the previously mentioned free end 62. More precisely, the rotor carrier 26 has a substantially tubular second support section 82 with a rotational drive profile 84, which follows the end 62 of the radial section 60 opposite to the rotor support section 46. Here, the second support section 82, extending in the axial directions 8, 10, is then constructed integrally with the rest of the rotor carrier 26. The second support section 82 is also configured to be offset outward in the radial direction 12 relative to the plate support section 28 of the plate carrier 24. In the illustrated embodiment, the end 62 of the radial section 60 is integrally incorporated into the second support section 82, such that the end 62 is no longer a free end, wherein the second support section 82 extends from the radial section 60 in the axial direction 10. In the fourth embodiment, the rotor support device 6 thus has two plate support sections 28, 82, and therefore the rotor support device 6 is particularly suitable for plate clutch 2 constructed as a double-plate clutch.

[0052] Figure 5 A fifth embodiment of the rotor support device 6 is shown, which substantially corresponds to the embodiment according to... Figures 2 to 4The implementation methods are as described above, so only the differences will be discussed below. The same or similar parts will be referred to by the same reference numerals, and the foregoing description will apply accordingly in other respects.

[0053] According to Figure 4 In contrast to the previous embodiment, the second support section 82, along with its rotational drive profile 84, is not constructed as part of the one-piece rotor bracket 26, but rather as a one-piece component of the plate bracket 24. Therefore, in the fifth embodiment, the second support section 82 is configured such that it follows the end 44 of the second fastening section 42 away from the plate support section 28. Similarly, in the fifth embodiment, the end 44 is integrally incorporated into the second support section 82 extending axially in the direction 10 from the second fastening section 42. In the fifth embodiment, similarly, the end 44 is integrally incorporated into the second support section 82 extending axially in the direction 10 from the second fastening section 42.

[0054] Although preferred, as in accordance with Figures 1 to 5 In the embodiment shown, the radial support of the rotor support device 6 is achieved via the support section 52 of the rotor bracket 26; however, it is also conceivable that there may be advantageous embodiments where this is not done. This sixth embodiment is shown in Figure 6 In this embodiment, which is basically the same as the aforementioned embodiment, only the differences are discussed below. The same or similar parts are referred to by the same reference numerals, and the foregoing description is similar or corresponding in other respects.

[0055] from Figure 6 As can be seen, in the sixth embodiment, the first fastening section 38 and the second fastening section 42 are constructed as a single component of the rotor bracket 26. Therefore, the support section 52 and the radial section 60 are also constructed as a single component of the plate bracket 24, with the support section 52 extending inward in the radial direction 14 beyond the free end 40 of the first fastening section 38, so as to achieve support in the radial directions 12, 14 via the aforementioned support hub 54. Thus, in this embodiment, the rotor bracket 56 can be indirectly supported or supported in the radial directions 12, 14 via the support section 52 of the plate bracket 24. Furthermore, the above references... Figures 1 to 5 The variant of the rotor support device 6 described in the embodiment can be adapted to the following: Figure 6 The implementation method is transferred in a similar manner.
