This structure does not increase the axial size, ensures that the axial space utilization is improved within the same wheel hub space, and can effectively improve the output torque of the wheel hub motor and improve the torque density of the wheel hub motor.

This structure does not increase the axial size and can effectively increase the output torque of the hub motor and improve the torque density of the hub motor only by reasonably utilizing the radial space inside the hub.

[0009] In some embodiments, the rotor structure includes a rotor support and a magnetic steel. A plurality of rotor supports are distributed at intervals along the axial direction of the rotor shaft, and the magnetic steel is disposed between two adjacent rotor supports.

[0010] In the above implementation process, the rotor bracket is configured with several magnets located between two adjacent rotor brackets, so that the rotor structure forms a yokeless structure, eliminating the traditional rotor core, shortening the magnetic path between the first stator assembly, the second stator assembly and the rotor, reducing the loss of the rotor structure, and also reducing the weight of the rotor structure, greatly improving the torque density of the hub motor, and at the same time, several magnets are separated by the rotor bracket, which can be used to suppress the eddy current loss generated on the magnets.

[0011] In some embodiments, the magnetic steel is configured to be conical along the radial direction of the rotor shaft, so that a gap is formed between the bottom of the magnetic steel and the rotor support.

[0019] In the above implementation process, the first sealing assembly and the second sealing assembly are respectively arranged on both sides of the shell assembly to seal the shell assembly cavity and achieve the waterproof and dustproof effect.

[0020] In a second aspect, the present application also provides a vehicle, comprising a flux hub motor as described in any one of the above items.

[0021] Since the vehicle provided in the second aspect includes a flux hub motor, the vehicle has all the technical effects of the flux hub motor, which will not be repeated here.

[0041] Example

[0042] With the rapid development of new energy vehicle technology, the torque density requirements for hub motors are getting higher and higher. The size of the hub where the hub motor is located is an important factor restricting the improvement of the hub motor's torque density. The topological structure of the hub motor directly affects the motor's torque density. Therefore, improving the hub motor's topological structure plays an important role in promoting high torque density motors.

[0043] During the design process, the inventors found that the current wheel hub motor topology has the following problems: 1. Multiple motors are arranged axially in parallel to increase torque. However, multiple motors occupy the axial space of the wheel hub, making the axial size of the wheel larger. 2. An outer rotor topology is adopted, with the rotor outside the stator to increase torque. However, in order to obtain a larger torque, the outer diameter of the motor core needs to be enlarged, occupying the radial space of the wheel hub, making the outer diameter of the wheel larger.

[0044] In view of this, if Figure 1-Figure 9 As shown, in the first aspect, an embodiment of the present application provides a flux hub motor, comprising: a motor assembly 100, comprising a hub bearing 101, a first stator assembly 102, a second stator assembly 103 and a rotor assembly 104, wherein the rotor assembly 104 is located between the first stator assembly 102 and the second stator assembly 103, the hub bearing 101 is arranged on the side of the first stator assembly 102 away from the rotor assembly 104, and a partial structure of the hub bearing 101 sequentially penetrates the first stator assembly 102, the rotor assembly 104 and the second stator assembly 103 along its axial direction; a fixing assembly 200, comprising a shell assembly and a fixing bracket 203, the shell assembly is configured to accommodate the first stator assembly 102, the second stator assembly 103 and the rotor assembly 104, the fixing bracket 203 is arranged on the side of the shell assembly away from the hub bearing 101, and the fixing bracket 203 is connected to the hub bearing 101.

[0045] For example, the hub motor technology is also called in-wheel motor technology. Its biggest feature is that the power, transmission and braking devices are integrated into the wheel hub, thereby greatly simplifying the mechanical part of the vehicle. The flux hub motor provided in this application can also be used in the wheel hub, which can solve the problem that the output torque of the hub motor cannot be further improved due to the small space of the wheel hub. It can improve the motor topology and realize the improvement of the output torque through the dual-stator single-rotor shaft 1041-directional flux topology structure.

[0046] It can be understood that the first stator assembly 102, the rotor assembly 104 and the second stator assembly 103 are arranged side by side, and the wheel hub bearing 101 is provided with one. After the wheel hub bearing 101 passes through the first stator assembly 102, the rotor assembly 104 and the second stator assembly 103, it is connected to the fixing bracket 203, so as to fix the first stator assembly 102, the rotor assembly 104 and the second stator assembly 103. At the same time, the first stator assembly 102 and the second stator assembly 103 share the wheel hub bearing 101, which reduces the number of bearings of the hub motor itself, simplifies the structure, and also reduces the bearing loss, which is beneficial to improving the efficiency of the hub motor.

[0047] In the above implementation process, the first stator assembly 102, the second stator assembly 103 and the rotor assembly 104 are arranged in the housing assembly, and the rotor assembly 104 is located between the first stator assembly 102 and the second stator assembly 103. After the wheel hub bearing 101 passes through the first stator assembly 102, the rotor assembly 104 and the second stator assembly 103, it is connected to the fixing bracket 203, so as to fix the three and realize the side-by-side arrangement of the first stator assembly 102 and the second stator assembly 103. This structure does not increase the axial size, ensures that the axial space utilization is improved within the same wheel hub space, and can effectively improve the output torque of the wheel hub motor and improve the torque density of the wheel hub motor.

[0048] like Figure 2 , Figure 3 and Figure 6 As shown, the rotor assembly 104 includes a rotor shaft 1041 and a rotor structure. The rotor shaft 1041 is connected to the wheel hub bearing 101 , and the rotor structure is connected to the rotor shaft 1041 .

[0049] Exemplarily, the rotor shaft 1041 is located at one side of the rotor structure, and the rotor shaft 1041 is connected to the hub bearing 101 , and can be used to limit the relative position of the rotor assembly 104 and the first stator assembly 102 and the second stator assembly 103 .

[0050] In the above implementation process, the rotor shaft 1041 is connected to the rotor structure and is located between the first stator assembly 102 and the second stator assembly 103, so that two stators are arranged axially side by side with a single rotor in the middle. This structure does not increase the axial size, but only through the reasonable use of the radial space inside the hub, it can effectively increase the output torque of the hub motor and improve the torque density of the hub motor.

[0051] like Figure 5 and Fig. 9 As shown, the rotor structure includes a rotor support 1042 and a magnetic steel 1043 . A plurality of rotor supports 1042 are distributed at intervals along the axial direction of the rotor shaft 1041 , and the magnetic steel 1043 is disposed between two adjacent rotor supports 1042 .

[0052] Exemplarily, the rotor bracket 1042 is made of non-magnetic stainless steel, and a plurality of the rotor brackets 1042 are configured, wherein the number of the rotor brackets 1042 is not specifically limited, and the number of the magnetic steels 1043 can be set according to the number of the rotor brackets 1042, which are not described one by one here; it can be understood that there is no conduction between the plurality of the rotor brackets 1042, and the magnetic steels 1043 are connected between two adjacent rotor brackets 1042, so that the plurality of magnetic steels 1043 are spaced apart, and at the same time, the magnetic steels 1043 are configured into a plurality of segments (for example, each of the magnetic steels 1043 is configured with eight segments, etc.), which can suppress the eddy current loss generated on the magnetic steels 1043.

[0053] In the above implementation process, the rotor bracket 1042 is configured with several magnets 1043 located between two adjacent rotor brackets 1042, so that the rotor structure forms a yokeless structure, eliminating the traditional rotor core, shortening the magnetic path between the first stator assembly 102, the second stator assembly 103 and the rotor, reducing the loss of the rotor structure, while also reducing the weight of the rotor structure, greatly improving the torque density of the hub motor, and at the same time, several magnets 1043 are separated by the rotor bracket 1042, which can be used to suppress the eddy current loss generated on the magnet 1043.

[0054] like Fig. 9 As shown, the magnetic steel 1043 is configured to be conical along the radial direction of the rotor shaft 1041 , so that a gap is formed between the bottom of the magnetic steel 1043 and the rotor support 1042 .

[0055] Exemplarily, the magnet 1043 is configured to be conical, so that the sizes of the two ends of the magnet 1043 are inconsistent, wherein the cross-sectional size of the upper end of the magnet 1043 is larger than the cross-sectional size of the lower end thereof, so that when the magnet 1043 is assembled on the rotor bracket 1042, the gap can be formed between the bottom of the magnet 1043 and the rotor bracket 1042. It can be understood that the size of the gap is not specifically limited and can be set according to the actual situation of the hub motor.

[0056] In the above implementation process, by forming the gap between the bottom of the magnetic steel 1043 and the rotor shaft 1041, the eddy current loss generated in the rotor bracket 1042 can be further suppressed, while ensuring that the rotor structure can cool the magnetic steel 1043 with air when rotating.

[0057] In some embodiments, the rotor bracket 1042 includes a first bracket and a second bracket, the first bracket is connected to the second bracket, the first bracket is configured with a first adapter part, the magnetic steel 1043 is configured with a second adapter part, and the first adapter part is configured to be adapted to the second adapter part.

[0058] Exemplarily, the first adapter portion includes but is not limited to an adapter groove, and the second adapter portion includes but is not limited to an adapter protrusion. The adapter protrusion can be set to a semicircular shape or a square shape, etc., so as to achieve the limitation of the magnetic steel 1043.

[0059] In the above implementation process, by adapting the first adapter part and the second adapter part, the magnet 1043 can be fixed on the rotor bracket 1042, so that the rotor bracket 1042 limits the axial movement of the magnet 1043, ensuring that the magnet 1043 maintains a fixed and small axial distance with the first stator assembly 102 and the second stator assembly 103 respectively.

[0060] In some embodiments, the thickness of the first bracket is smaller than the thickness of the magnetic steel 1043 , so as to reduce the eddy current loss generated on the rotor bracket 1042 .

[0061] like Figure 2-Figure 3 As shown, the rotor structure further includes a carbon fiber ring 1044, and the carbon fiber ring 1044 is wound around a side of the magnetic steel 1043 away from the second bracket.

[0062] Exemplarily, after the magnetic steel 1043 is assembled on the rotor support 1042, carbon fiber is wound around the outer edge thereof to form the carbon fiber ring 1044, which can prevent the magnetic steel 1043 from moving radially under the action of centrifugal force.

[0063] In some embodiments, the first stator assembly 102 and the second stator assembly 103 have the same number of stator teeth and the same number of stator slots, and the first stator assembly 102 and the second stator assembly 103 have the same size. The axial structural space in the wheel hub can be fully utilized without increasing the axial size, without affecting the wheel hub size, and the output torque of the wheel hub motor can be effectively improved, thereby improving the torque density of the wheel hub motor.

[0064] Exemplarily, the stator core of the first stator assembly 102 is formed by stamping and then winding thin silicon steel sheets, and its winding adopts concentrated winding or distributed winding. The stator core of the second stator assembly 103 is formed by stamping and then winding thin silicon steel sheets, and its winding adopts concentrated winding or distributed winding.

[0065] It can be understood that the housing assembly includes a front end cover 201 and a rear end cover 202, the first stator assembly 102 is mounted on the front end cover 201, the second stator assembly 103 is mounted on the rear end cover 202, and they are fixed by bolts respectively to prevent axial movement of the first stator assembly 102 and the second stator assembly 103, and the rear end cover 202 is fixed to the outer flange of the hub bearing 101 through the fixing bracket 203.

[0066] In some embodiments, the flux hub motor also includes a sealing assembly 300, and the sealing assembly 300 includes a first sealing assembly and a second sealing assembly, wherein the first sealing assembly and the second sealing assembly are located on the outside of the shell assembly, and the first sealing assembly is located at one end of the shell assembly, and the second sealing assembly is located at the other end of the shell assembly.

[0067] Exemplarily, the sealing assembly 300 includes a front sealing ring 301 and a rear sealing ring 302. The front sealing ring 301 is arranged between the first stator assembly 102 and the rotor shaft 1041, and the rear sealing ring 302 is arranged between the second stator assembly 103 and the rotor shaft 1041, thereby achieving a sealing effect; of course, the sealing assembly 300 also includes a front sealing baffle 303 and a rear sealing baffle 304. The front sealing baffle 303 is arranged on the outside of the front sealing ring 301, and the rear sealing baffle 304 is arranged on the outside of the rear sealing ring 302, which can respectively provide mechanical protection for the front sealing ring 301 and the rear sealing ring 302.

[0068] It should be noted that the linear speeds of the front sealing ring 301 and the rear sealing ring 302 are low, which is beneficial to improving the service life of the front sealing ring 301 and the rear sealing ring 302 .

[0069] In the above implementation process, the first sealing assembly and the second sealing assembly are respectively arranged on both sides of the shell assembly to seal the shell assembly cavity and achieve the waterproof and dustproof effect.

[0070] In a second aspect, the present application further provides a vehicle, including the flux hub motor as described above. The vehicle may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended range vehicle, etc.

[0071] Since the vehicle provided in the second aspect includes a flux hub motor, the vehicle has all the technical effects of the flux hub motor, which will not be repeated here.

[0072] In all the embodiments of the present application, "big" and "small" are relative, "more" and "less" are relative, and "up" and "down" are relative. The expressions of such relative terms are not elaborated in the embodiments of the present application.
