Description

The invention relates to a drive torque generating and / or transmitting device for a vehicle. The invention likewise relates to a method for mounting at least one eddy current brake on and / or in a vehicle.Prior ArtEddy current brakes are known from the prior art, such as DE 10 2021 214 867 A1, for example, by means of which a vehicle equipped with such an eddy current brake can be braked.Disclosure of the InventionThe present invention provides a drive torque generating and / or transmitting device for a vehicle having the features of claim 1, a method for mounting at least one eddy current brake on and / or in a vehicle having the features of claim 7 and a method for mounting at least one eddy current brake on and / or in a vehicle having the features of claim 8.Advantages of the InventionThe present invention provides a (mechanical) integration of at least one eddy current brake into a drive torque generating and / or transmission device of a vehicle using the invention. Since the (mechanical) integration of the at least one eddy current brake into the respective drive torque generating and / or transmitting device does not / hardly require an enlargement of a housing of the drive torque generating and / or transmitting device, installation space on the respective vehicle can be saved by means of the present invention. In addition, the present invention contributes to the fact that unpleasant noises, which can arise during operation of the at least one eddy current brake, are not transmitted on by means of the housing of the drive torque generating and / or transmission device. A person in the respective vehicle is therefore not irritating due to unpleasant noises even when the at least one eddy current brake is put into heavy use. At the same time, in the case of a use of the present invention, the transmission of the unpleasant noises can be prevented without the at least one eddy current brake being equipped with a respective "dedicated" eddy current brake housing for this purpose. An installation space requirement, a weight and production costs of at least one eddy current brake housing can therefore be saved by means of the present invention.In an advantageous embodiment of the drive torque generation and / or transmission device, the at least one brake disk is mounted on and / or on a shaft of at least one drive torque generation and / or transmission component of the drive torque generation and / or transmission device or of an electric motor of the vehicle external to the housing. In the embodiment of the drive torque generating and / or transmitting device described here, the conventional need to provide a "dedicated brake disk shaft" for the at least one brake disk is thus eliminated. Instead, a "free shaft end" of the shaft of the at least one drive torque generating and / or transmitting component or of the housing-external electric motor can additionally be used for the at least one brake disk. By increasing multifunctionality of the respective shaft, installation space and costs can be saved. At the same time, it can be used in the embodiment described here that the respective shaft is usually relatively stable on account of its use for the at least one drive torque generation and / or transmission component or for the electric motor external to the housing, and is therefore well suited for cooperation with the at least one brake disk.The at least one eddy current brake preferably comprises at least one holder, to which its at least one coil is fastened, and which is mounted on the shaft in such a way that a co-rotational movement of the at least one holder together with the rotating shaft is prevented. The at least one coil of the at least one eddy current brake can therefore be positioned advantageously with respect to the at least one interacting brake disc of the at least one eddy current brake.In a further advantageous embodiment of the drive torque generating and / or transmitting device, the at least one holder of the at least one eddy current brake is integrated into a bearing shield of the drive torque generating and / or transmitting device. In this case, the at least one bearing shield can advantageously be used as part of the housing of the drive torque generating and / or transmission device. This can contribute to cost reduction in the design of the housing of the drive torque generating and / or transmission device.Alternatively, if the drive torque generating and / or transmitting device comprises an electric motor with an outer stator and an inner rotor, the at least one coil of the at least one eddy current brake and the at least one brake disc of the at least one eddy current brake can be arranged together with the inner rotor within a volume framed by the outer stator. This enables a space-saving (mechanical) integration of the at least one eddy current brake into the housing of the drive torque generating and / or transmitting device, which facilitates a minimization of the drive torque generating and / or transmitting device.For example, the drive torque generating and / or transmitting device may be a traction machine, an e-axle, an electric vehicle drive machine, a vehicle central transmission, a single-wheel drive machine or a single-wheel transmission. The present invention is thus versatile. However, it is pointed out that the examples listed here of possible embodiments of the drive torque generating and / or transmission device should not be interpreted as exhaustive.Likewise, carrying out a corresponding method for mounting at least one eddy current brake on and / or in a vehicle also provides the advantages explained above. It is expressly pointed out that the respective methods can be carried out comparatively easily. In addition, the methods according to the embodiments of the drive torque generation and / or transmission device explained above can be further developed.Brief Description of the DrawingsFurther features and advantages of the present invention are explained below with reference to the figures. The following are shown: FIG. 1 shows a schematic illustration of a first embodiment of the drive torque generating and / or transmission device; FIG. 2 shows a schematic illustration of a second embodiment of the drive torque generating and / or transmission device; FIG. 3 shows a schematic illustration of a third embodiment of the drive torque generating and / or transmission device; FIG. 4 shows a schematic illustration of a fourth embodiment of the drive torque generating and / or transmission device; FIGS. 5 aand 5 b show schematic representations of a fifth embodiment of the drive torque generating and / or transmission device; FIG. 6 shows a schematic illustration of a sixth embodiment of the drive torque generating and / or transmission device; FIG. 7 is a flow chart for explaining a first embodiment of the method for mounting at least one eddy current brake on and / or in a vehicle; and FIG. 8 is a flow chart for explaining a second embodiment of the method for mounting at least one eddy current brake on and / or in a vehicle.Embodiments of the InventionFIG. 1 shows a schematic illustration of a first embodiment of the drive torque generating and / or transmission device.The drive torque generating and / or transmitting device 10 schematically represented in FIG. 1 is mountable / mounted on and / or in a vehicle / motor vehicle (not shown). It is noted that a usability of the drive torque generation and / or transmission device 10 is not limited to a specific vehicle type / motor vehicle type of the vehicle / motor vehicle.The drive torque generating and / or transmitting device 10 described below can be understood to mean a device 10 by means of which a drive torque of the vehicle equipped therewith can be / is generated, i.e. at least one vehicle component of the vehicle can be / is displaced into a (positive) linear acceleration or a (positive) rotational acceleration, and / or by means of which a (positive) drive torque can / is transmitted. Advantageous examples of the drive torque generating and / or transmitting device 10 are described below.The drive torque generating and / or transmitting device 10 has a housing 10 a, which is able to be installed / installed on and / or in the respective vehicle / motor vehicle. The housing 10 aof the drive torque generation and / or transmission device 10 means a housing component 10 awhich surrounds at least one drive torque generation and / or transmission component 12 and 14 of the drive torque generation and / or transmission device 10 at least partially, preferably completely, in all three spatial directions. Preferably, the housing 10 asurrounds all parts of the drive torque generating and / or transmission device 10 in all three spatial directions at least partially or completely. Examples of the at least one drive torque generation and / or transmission component 12 and 14 are listed below.In addition, at least one coil 16 aof at least one eddy current brake 16 and at least one interacting brake disc / reaction disc 16 bof the at least one eddy current brake 16 are arranged within the housing 10 aof the drive torque generating and / or transmitting device 10. The drive torque generating and / or transmitting device 10 described here therefore has a (mechanical) integration of the at least one eddy current brake 16 into its housing 10 a. Preferably, all eddy current brake parts 16 ato 16 cof the at least one eddy current brake 16 are arranged within the housing 10 aof the drive torque generating and / or transmitting device 10. It is pointed out that an arrangement within the housing 10 aof the drive torque generation and / or transmission device 10 can also be understood to mean a (mechanical) integration of the respective eddy current brake part 16 ato 16 cin the housing 10 aof the drive torque generation and / or transmission device 10. Due to the (mechanical) integration of the at least one eddy current brake 16 into the housing 10 a, the housing 10 acan be used not only for spatially shielding the at least one drive torque generating and / or transmitting component 12 and 14 of the drive torque generating and / or transmitting device 10, but also for spatially shielding the at least one eddy current brake 16. Multifunctionality of the housing 10 ais thus increased.For example, the housing 10 acan be used to prevent transmission of unpleasant noises, such as can occur during the operation of the at least one eddy current brake 10 a. The housing 10 athus improves user comfort during the operation of the at least one eddy current brake 16, without a "separate" eddy current brake housing of the at least one eddy current brake 16 being necessary for this purpose. The (mechanical) integration of the at least one eddy current brake 16 into the housing 10 acan therefore also be used for cost saving and weight saving.A further advantage of the (mechanical) integration of the at least one eddy current brake 16 into the housing 10 ais the possibility realized in this way for the co-use of a cooling device (not shown) of the drive torque generating and / or transmitting device 10 for the at least one eddy current brake 16. The cooling device may be, for example, a water cooling device and / or an oil cooling device.As can also be seen in FIG. 1, the (mechanical) integration of the at least one eddy current brake 16 into the housing 10 ais also possible without a (substantial) increase in its spatial dimensions. The (mechanical) integration of the at least one eddy current brake 16 into the housing 10 ais therefore generally more space-saving than a use of the at least one eddy current brake 16 outside the housing 10 a. This can also be used to save installation space on the vehicle.As can additionally be seen in FIG. 1, the at least one brake disk 16 bof the at least one eddy current brake 16 can be mounted on and / or on a shaft 12 (as a drive torque generation and / or transmission component 12), on and / or on which at least one (further) drive torque generation and / or transmission component 14 of the drive torque generation and / or transmission device 10 is also mounted. For the at least one brake disk 16 bof the at least one eddy current brake 16, the shaft 12 of the at least one (further) drive torque generation and / or transmission component 14 of the drive torque generation and / or transmission device 10 can thus be used as shaft 12. This also eliminates a conventional need for providing a "dedicated" brake disk shaft for the at least one brake disk 16 b, as a result of which at least one bearing shield, at least one sealing ring and / or at least one bearing for the at least one brake disk shaft can be dispensed with. It is also pointed out that, as a result of the omission of additional bearings and sealing rings, fewer friction losses occur, which reduces operating losses of the overall arrangement illustrated in FIG. 1. In addition to multifunctionality of the shaft 12, multifunctionality of at least one bearing 18 used for positioning the shaft 12 is also ensured by means of the (mechanical) integration of the at least one eddy current brake 16 into the housing 10 a. This also contributes to saving costs and installation space.In the embodiment of FIG. 1, the drive torque generating and / or transmitting device 10 has, as its at least one drive torque generating and / or transmitting component 12 and 14, for example an electric motor 14 (as a further drive torque generating and / or transmitting component 14), which can have, for example, an outer stator 14 aand an inner rotor 14 b. The equipment of the electric motor 14 with two balancing disks 14 carranged on both sides, which is depicted graphically in FIG. 1, is to be interpreted only as an example. The drive torque generating and / or transmitting device 10 of FIG. 1 can therefore be, in particular, a (central) electric vehicle drive machine or a single-wheel drive machine. A particular advantage of using the shaft 12 of the electric motor 14 for mounting the at least one brake disk 16 bis that the shaft 12 and the at least one co-rotating brake disk 16 b frequently have relatively high rotational speeds, which ensures a strong braking effect of a magnetic field generated by means of an energization of the at least one coil 16 aof the at least one eddy current brake 16 on the at least one brake disk 16 band possibly on at least one wheel of the vehicle mechanically connected to the shaft 12.The at least one eddy current brake 16 is preferably formed with in each case at least one holder 16 cto which its at least one coil 16 ais fastened. The respective holder 16 cof the at least one eddy current brake 16 can also be referred to as an eddy current brake stator 16 c. The at least one holder 16 of the at least one eddy current brake 16 can be mounted on and / or on the shaft 12 in such a way that a co-rotational movement of the holder 16 ctogether with the rotating shaft 12 is prevented. Merely by way of example, in the embodiment of FIG. 1, the at least one holder 16 cof the at least one eddy current brake 16 is integrated in a respective bearing shield 20 of the drive torque generating and / or transmitting device 10. Since the at least one bearing plate 20 can also be used as part of the housing 10 a, a weight of the drive torque generating and / or transmission device 10 can be minimized in a simple manner.FIG. 2 shows a schematic illustration of a second embodiment of the drive torque generating and / or transmission device.The drive torque generating and / or transmitting device 10 schematically represented in FIG. 2 has two eddy current brakes 16 instead of a single eddy current brake 16 as a development to the previously described embodiment. As can be seen in FIG. 2, a first eddy current brake 16 is mounted on and / or on the shaft 12 on a first side of the electric motor 14, while a second eddy current brake 16 is arranged on and / or on the shaft 12 on a second side of the electric motor 14 directed away from the first side. Axial forces generated by means of simultaneous operation of the two eddy current brakes are thus lifted out, whereby a load on the at least one bearing 18 is reduced. Accordingly, a helical toothing is also cancelled out by one another. In addition, by means of the two eddy current brakes 16, double braking power can be effected on the at least one wheel which is mechanically connected to the shaft 12. The provision of the drive torque generating and / or transmitting device 10 with two eddy current brakes 16 can, however, also be used to reduce their size.As is also schematically shown in FIG. 2, by means of an arrangement of the two brake disks 16 bof the two eddy current brakes 16 close enough to the inner rotor 14 bof the electric motor 14, each of the brake disks 16 bcan also be used for balancing. It is thus possible to dispense with the provision of balancing disks 14 cof the electric motor 14, as shown in the embodiment described above.With regard to further properties and features of the drive torque generating and / or transmitting device 10 of FIG. 2 and its advantages, reference is made to the description of the preceding embodiment of FIG. 1.FIG. 3 shows a schematic representation of a third embodiment of the drive torque generating and / or transmission device.In the embodiment of FIG. 3, the at least one coil 16 aof the at least one eddy current brake 16 and the at least one brake disk 16 bof the at least one eddy current brake 16 are arranged together with the inner rotor 14 bwithin a volume 22 framed by the outer stator 14 aof the electric motor 14. The volume 22 framed by the outer stator 14 aof the electric motor 14 can also be referred to as a so-called inner installation space 22 of the outer stator 14 aof the electric motor 14. By means of the realized (mechanical) integration of the at least one eddy current brake 16 into the inner installation space 22 of the outer stator 14 aof the electric motor 14, installation space on the vehicle equipped with the drive torque generating and / or transmitting device 10 can be saved. Likewise, by means of the arrangement of the at least one brake disk 16 bof the at least one eddy current brake 16 in the inner installation space 22 of the outer stator 14 aof the electric motor 14, at least one balancing disk 14 c, as is shown in the embodiment of FIG. 1, can be saved. Instead, the balancing can be realized by means of the at least one brake disk 16 b.Two eddy current brakes 16 are preferably (mechanically) integrated into the inner installation space 22 of the outer stator 14 aof the electric motor 14. As depicted in FIG. 3, a first eddy current brake 16 may optionally be arranged on a first side of the inner rotor 14 bon and / or on the shaft 12, and a second eddy current brake 16 on the second side of the inner rotor 14 bdirected away from the first side on and / or on the shaft 12.With regard to further properties and features of the drive torque generating and / or transmitting device 10 of FIG. 3 and its advantages, reference is made to the description of the embodiments of FIGS. 1 and 2.It is again pointed out that all the embodiments of drive torque generating and / or transmitting devices 10 described above can each be a central drive motor and also a single-wheel drive motor.FIG. 4 shows a schematic illustration of a fourth embodiment of the drive torque generating and / or transmission device.The drive torque generating and / or transmitting device 10 of FIG. 4 equipped with the at least one integrated eddy current brake 16 in its housing 10a has transmission components 24 as its drive torque generating and / or transmitting components 24. The drive torque generating and / or transmitting device 10 of FIG. 4 is thus a transmission. The drive torque generating and / or transmitting device 10 of FIG. 4 can be referred to in particular as a central vehicle transmission, via which a drive torque generated by means of an electric motor 26 external to the housing of the vehicle equipped therewith can be transmitted to at least one wheel 28 of the vehicle. The (mechanical) integration of the at least one eddy current brake 16 into the housing 10 aof the transmission offers the advantage that electromagnetic interactions between the at least one eddy current brake 16 and the housing-external electric motor 26 of the vehicle are avoided.As can be seen from FIG. 4, the (mechanical) integration of the at least one eddy current brake 16 into the housing 10 aof the transmission can be realized in a compact manner without an additional bearing or an additional sealing ring being required for this purpose. It is also advantageous to mount at least the at least one brake disk 12 bof the at least one eddy current brake 16 on and / or on the shaft 12 of the transmission, which rotates at the current engine speed of the housing-external electric motor 26. This requires only a slight extension of the shaft 12.With regard to further properties and features of the drive torque generating and / or transmitting device 10 of FIG. 4 and its advantages, reference is made to the description of the embodiments of FIGS. 1 to 3.FIGS. 5 aand 5 b show schematic representations of a fifth embodiment of the drive torque generating and / or transmission device.In contrast to the previously described embodiment of FIG. 4, in the drive torque generating and / or transmission device 10 of FIGS. 5 aand 5 b, the holder 16 cof the respective eddy current brake 16 is configured only as a pitch circular surface, i.e. as an "incomplete" circular surface which "lacks" an intersection of the "complete" circular surface with an adjacent gear 30. Therefore, the bracket 16 cof each eddy current brake 16 may be positioned in the same plane with the immediately adjacent adjacent gear 30.With regard to further properties and features of the drive torque generating and / or transmitting device 10 of FIG. 5 and its advantages, reference is made to the description of the embodiments of FIGS. 1 to 4.FIG. 6 shows a schematic representation of a sixth embodiment of the drive torque generating and / or transmission device.While the transmissions of FIGS. 4 and 5 are designed as central vehicle transmissions, FIG. 6 shows a single-wheel transmission as a drive torque generating and / or transmitting device 10.With regard to further properties and features of the drive torque generating and / or transmitting device 10 of FIG. 6 and its advantages, reference is made to the description of the embodiments of FIGS. 1 to 5.As will be apparent from the foregoing description, the drive torque generating and / or transmitting device 10 may be, for example, a traction machine, an e-axle, a vehicle electric drive machine, a vehicle center transmission, a single wheel drive machine, or a single wheel transmission. The design possibilities listed here for the drive torque generating and / or transmitting device 10 are not to be interpreted as exhaustive, however. It is also pointed out here that, despite the at least one (mechanically) integrated eddy current brake 16, the drive torque generating and / or transmitting device 10 should not be understood as a "pure brake device", i.e. a device exclusively designed for braking the vehicle.The above-described embodiments of drive torque generating and / or transmitting devices 10 all have eddy current brakes 16, each having a brake disk 16b per eddy current brake 16 and a holder 16c with at least one coil 16a per eddy current brake 16 fastened thereto. However, it is pointed out that corresponding drive torque generating and / or transmitting devices 10 can also be realized with at least one eddy current brake 16, which comprises at least two brake disks 16 band / or at least two holders 16 cwith at least one coil 16 afixed thereto.In all the embodiments explained above, the brake disk 16 bis mounted on the shaft 12 in such a way that a braking force exerted on the brake disk 16 bby means of the energization of the at least one coil 16 ais transmitted to the shaft 12 via a mechanical contact of the brake disk 16 bwith the shaft 12. However, this is not necessary. Instead, the brake disk 16 bmay also be mounted on the shaft 12 in such a way that a mechanical contact of the brake disk 16 bwith the shaft 12 is prevented by means of at least one intermediate piece. Specifically, the brake disc 16 band the intermediate piece can also be formed as a compact unit.Furthermore, it is also pointed out that the configuration of the brake disc 16 bof the embodiments explained above with a (substantially) disc-shaped form is to be interpreted only as an example. For example, the brake disc 16 bmay also have a "pot-like" or "drum-like" shape without this impairing an interaction of the brake disc 16 bwith the at least one coil 16 a. Likewise, an alignment / positioning of the at least one coil 16 awith respect to the brake disc 16 bmay also be selected with a great freedom of design.FIG. 7 shows a flow chart for explaining a first embodiment of the method for mounting at least one eddy current brake on and / or in a vehicle.In a method step S 1 of the method described here, at least one coil of the at least one eddy current brake and at least one brake disk of the at least one eddy current brake interacting with the at least one coil are arranged within a housing of a later drive torque generating and / or transmitting device of the vehicle. Examples for carrying out such a (mechanical) integration of the at least one eddy current brake have already been explained above. For example, the at least one brake disk can be mounted on and / or on a shaft of at least one drive torque generation and / or transmission component of the drive torque generation and / or transmission device or of an electric motor of the vehicle external to the housing. Preferably, in this case, at least one holder of the at least one eddy current brake, to which its at least one coil is fastened, is mounted on the shaft in such a way that a co-rotational movement of the at least one holder together with the rotating shaft is prevented.As method step S 2, the drive torque generating and / or transmitting device is subsequently mounted on and / or in the vehicle with the at least one coil of the at least one eddy current brake arranged within the housing and with the at least one brake disk of the at least one eddy current brake arranged within the housing. Such an assembly can be easily carried out and is hardly associated with any work.FIG. 8 shows a flow chart for explaining a second embodiment of the method for mounting at least one eddy current brake on and / or in a vehicle.As method step S 10 of the method described here, a drive torque generating and / or transmitting device is mounted on and / or in the vehicle. Examples of a suitable drive torque generating and / or transmitting device are already listed above.Thereafter, in a method step S 11, at least one coil of the at least one eddy current brake and at least one brake disk of the at least one eddy current brake, which brake disk interacts with the at least one coil, are arranged within a housing of the drive torque generating and / or transmitting device mounted on and / or in the vehicle. Method step S 11 is also easily executable and hardly associated with any work. In particular, the at least one brake disk can be mounted on and / or on a shaft of at least one drive torque generation and / or transmission component of the drive torque generation and / or transmission device or of an electric motor of the vehicle external to the housing. For this purpose, at least one holder of the at least one eddy current brake, to which its at least one coil is fastened, is preferably mounted on the shaft in such a way that a co-rotational movement of the at least one holder together with the rotating shaft is prevented.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
