The resolver wiring harness of the resolver sensor connected to the resolver stator passes through a hole on the rear cover of the hybrid housing and is connected to the MCU (Microcontroller Unit).

[0004] However, the resolver sensor is located at the rear of the hybrid housing, which requires additional space to accommodate the resolver stator when designing the rear cover of the hybrid housing, thus increasing the axial dimension of the hybrid housing on the motor shaft.

[0019] The accompanying drawings have illustrated specific embodiments of this disclosure, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this disclosure to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this disclosure can be combined with each other. This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] In a hybrid transmission, the rotational state and parameters of the motor shaft are related to the vehicle's driving state. For example, the shaft can rotate forward and reverse; forward rotation drives the vehicle forward, while reverse rotation drives it backward. Furthermore, the shaft's rotational speed is related to the vehicle's speed. Therefore, it is crucial to detect and obtain the shaft's position, direction, and rotational speed using a resolver sensor. In related technologies, the resolver sensor is typically positioned at the rear end of the hybrid transmission, with the resolver rotor mounted at the rear end of the motor shaft and the resolver stator fixed to the rear cover of the hybrid transmission. It should be noted that in this configuration, the resolver sensor is located on the path of the hybrid transmission's axial critical dimension chain, thus affecting the hybrid transmission's axial dimensions and consequently increasing its volume.

[0023] This disclosure provides a hybrid storage box 1. (See reference...) Figure 1 and Figure 2The hybrid housing 1 includes a first housing 10, a motor 11, and a resolver sensor 12. The motor 11 is disposed inside the first housing 10. The resolver sensor 12 is disposed inside the first housing 10, and the resolver stator 121 of the resolver sensor 12 is fixed inside the first housing 10. The resolver rotor 122 of the resolver sensor 12 is sleeved on the rotating shaft 111 of the motor 11 and is located at the front end of the rotating shaft 111, wherein the front end of the rotating shaft 111 is used to connect to the gear shaft 13.

[0024] refer to Figure 1 and Figure 3 The hybrid gearbox 1 may also include an output gear shaft 16 and a differential 17. The rotating shaft 111 of the motor 11 is connected to the gear shaft 13, and the gear shaft 13 is connected to the differential 17 through the output gear shaft 16. When the rotating shaft 111 of the motor 11 rotates, it can transmit power to the differential 17 in sequence through the gear shaft 13 and the output gear shaft 16, thereby outputting power through the differential 17.

[0025] Among them, reference Figure 2 The gear shaft 13 includes a shaft body 131 and a gear part 132. The shaft body 131 can be roughly regarded as a rod with a certain length. One end of the shaft body 131 is connected to the gear part 132, and the other end can at least partially pass through the rotating shaft 111 and be connected to the rotating shaft 111.

[0026] For example, refer to Figure 5 ,like Figure 5 The arrow chain shown typically represents the path of the axial critical dimension chain of the hybrid housing 1. There is usually an existing area at the front end of the motor 11 shaft 111 that is not on the axial critical dimension chain path. By fitting the resolver rotor 122 of the resolver sensor 12 onto this existing area at the front end of the shaft 111, compared to placing the resolver rotor 122 of the resolver sensor 12 at the rear end of the motor 11 shaft 111, the resolver sensor 12 will not affect the gears of the hybrid housing 1 in the axial direction of the shaft 111. This means the axial dimension of the hybrid housing 1 can be reduced, thereby compressing its volume and allowing it to be adapted to more vehicle models.

[0027] By employing the technical solution provided in this disclosure embodiment, the resolver sensor 12 is arranged at the front end of the motor 11 shaft 111, which avoids the path of the axial critical dimension chain between the resolver sensor 12 and the hybrid box 1. This arrangement of the resolver sensor 12 at the front end of the motor 11 shaft 111 will not affect the axial dimension of the hybrid box 1. Compared with arranging the resolver rotor 122 of the resolver sensor 12 at the rear end of the motor 11 shaft 111, this is equivalent to compressing the axial dimension of the hybrid box 1, thereby reducing the volume of the hybrid box 1.

[0028] In some possible implementations, refer to Figure 1 and Figure 2 The front end of the rotating shaft 111 is fitted with a first bearing 112, and the rear end of the rotating shaft 111 is fitted with a second bearing 113. The resolver rotor 122 is located on the side of the first bearing 112 away from the second bearing 113.

[0029] The first bearing 112 and the second bearing 113 are used to support the rotation of the rotating shaft 111. For example, the first bearing 112 can provide axial positioning and radial support for the rotating shaft 111. The first bearing 112 bears the thrust along the axial direction of the rotating shaft 111, fixing the rotating shaft 111 approximately in a defined position axially, thus preventing axial movement of the rotating shaft 111. In addition, the first bearing 112 can withstand a large radial load. The second bearing 113 works in conjunction with the first bearing 112 to provide stable support for the rotating shaft 111, increasing rigidity and reducing deflection and vibration of the rotating shaft 111.

[0030] For example, refer to Figure 5 ,like Figure 5 The arrow chain shown (indicated by the black arrow chain) typically represents the path of the axial critical dimension chain of the hybrid gearbox 1. This path can include three regions. The first region can be located on the shaft 111 of the motor 11, for example, the area between the second bearing 113 and the first bearing 112 on the shaft 111; this region is on the path of the axial critical dimension chain of the hybrid gearbox 1. The second region can be located on the gear shaft 13, for example, the gear portion 132 of the gear shaft 13; this region is on the path of the axial critical dimension chain of the hybrid gearbox 1. The third region can be located on the output gear shaft 16, for example, the area of ​​the output gear shaft 16 axially between the first bearing 112 and the gear portion 132 on the shaft 111; this region is on the path of the axial critical dimension chain of the hybrid gearbox 1. In other words, the dimensions of these three regions can affect the axial dimensions of the hybrid gearbox 1.

[0031] It is understandable that, in the axial direction of the motor 11 shaft 111, the existing area of ​​the shaft 111 located on the side of the first bearing 112 away from the second bearing 113 is located in the third part of the output gear shaft 16. The axial dimension of this existing area can be determined by the dimension of the third part of the output gear shaft 16. Therefore, by setting the resolver rotor 122 of the resolver sensor 12 on the side of the first bearing 112 away from the second bearing 113, that is, by setting the resolver rotor 122 in the existing area of ​​the shaft 111 located on the side of the first bearing 112 away from the second bearing 113, the path of the axial critical dimension chain of the hybrid box 1 is avoided. Compared with arranging the resolver rotor 122 of the resolver sensor 12 at the rear end of the motor 11 shaft 111, it is equivalent to compressing the axial dimension of the hybrid box 1, thereby reducing the volume of the hybrid box 1.

[0032] In some possible implementations, refer to Figure 1 , Figure 3 and Figure 4 The first housing 10 has a first cavity 100 and a second cavity 101. The first cavity 100 is used to accommodate the motor 11, and the second cavity 101 is used to accommodate the gear shaft 13. The rotating shaft 111 of the motor 11 is located in the second cavity 101 and connected to the gear shaft 13. The resolver stator 121 of the resolver sensor 12 is fixed to the second cavity 101, and the resolver rotor 122 of the resolver sensor 12 is sleeved on the portion of the rotating shaft 111 located in the second cavity 101.

[0033] The gear shaft 13, output gear shaft 16, and differential 17 can all be housed within the second cavity 101. The stator and rotor of the motor 11 are located within the first cavity 100, and the rotating shaft 111 of the motor 11 extends from the first cavity 100 into the second cavity 101 to connect with the gear shaft 13.

[0034] It is understandable that the first bearing 112 can usually be located inside the first cavity 100 and near the edge of the second cavity 101. Therefore, the part of the motor 11 shaft 111 that extends into the second cavity 101 can usually be the existing area mentioned above. The resolver rotor 122 of the resolver sensor 12 is fitted onto the part of the shaft 111 located in the second cavity 101, that is, the resolver rotor 122 is arranged in this existing area, avoiding the path of the axial critical dimension chain of the hybrid box 1. Compared with arranging the resolver rotor 122 of the resolver sensor 12 at the rear end of the motor 11 shaft 111, it is equivalent to compressing the axial dimension of the hybrid box 1, thus reducing the volume of the hybrid box 1.

[0035] On the other hand, it is understandable that in related technologies, the resolver sensor 12 is arranged at the rear end of the hybrid housing 1. Since the rear end of the motor 11 shaft 111 is close to the stator winding terminals of the motor 11, the magnetic field generated by the stator winding terminals may cause electromagnetic interference to the resolver sensor 12. Therefore, it is usually necessary to install a magnetic shield to eliminate the electromagnetic interference generated by the stator winding terminals to the resolver sensor 12. However, in the technical solution of this disclosure, since the resolver sensor 12 is arranged in the second cavity 101, located outside the stator winding terminals of the motor 11 in the first cavity 100, and far away from the stator winding terminals of the motor 11 in the first cavity 100, the resolver sensor 12 is far away from the current interference of the stator winding terminals of the motor 11. Compared with arranging the resolver sensor 12 at the rear end of the hybrid housing 1, which requires the installation of a magnetic shield, the magnetic shield can be eliminated.

[0036] In some possible implementations, the first housing 10 has a through-hole (not shown), through which the first cavity 100 and the second cavity 101 are connected. The shaft 111 of the motor 11 extends into the second cavity 101 through the through-hole to connect with the gear shaft 13. The resolver stator 121 of the resolver sensor 12 is located at the edge of the second cavity 101 where the through-hole is located.

[0037] The exit hole located at the edge of the second cavity 101 is typically in the existing area of ​​the first bearing 112 on the shaft 111, away from the second bearing 113. Therefore, arranging the resolver stator 121 at the edge of the exit hole in the second cavity 101 avoids the path of the axial critical dimension chain of the hybrid housing 1. Compared to arranging the resolver rotor 122 of the resolver sensor 12 at the rear end of the motor 11 shaft 111, this effectively compresses the axial dimension of the hybrid housing 1, thus reducing its volume. Furthermore, arranging the resolver stator 121 at the edge of the exit hole in the second cavity 101 also prevents the resolver sensor 12 from interfering with other components within the second cavity 101.

[0038] In some possible implementations, the resolver harness 123 of the resolver sensor 12 is connected to the resolver stator 121. The hybrid housing 1 also includes a controller (not shown) electrically connected to the resolver harness 123 for acquiring the rotational speed and direction of rotation of the shaft 111 via the resolver sensor 12.

[0039] The resolver harness 123 may include a set of excitation windings, a set of sine windings, and a set of cosine windings. The excitation windings, sine windings, and cosine windings are all wound around the resolver stator 121 of the resolver sensor 12, and the terminals of the excitation windings, the sine windings, and the cosine windings are all connected to the controller.

[0040] The controller receives signals from the resolver harness 123 to obtain the angular position, speed and direction of rotation of the shaft 111, thereby achieving closed-loop precise control of the torque and speed of the motor 11, which can ensure smooth vehicle power and rapid response.

[0041] In some possible implementations, refer to Figure 1 The hybrid housing 1 also includes a second housing 15, which is connected to the first housing 10 and is used to house the controller.

[0042] Understandably, the second housing 15 is connected to the first housing 10, and the controller is housed within the second housing 15, effectively integrating the controller into the hybrid housing 1. This reduces the length of the resolver harness 123, lowers transmission loss, and improves transmission efficiency and power density. Simultaneously, it optimizes the overall layout space of the hybrid housing 1, reducing harness complexity and weight, aligning with the development trend of lightweighting and high integration in new energy vehicles. Furthermore, when controller maintenance is required, only the second housing 15 needs to be disassembled, eliminating the need to open the first housing 10, thus reducing maintenance costs and saving maintenance time.

[0043] The second housing 15 can be made of metals such as aluminum alloy. The second housing 15 itself forms a complete electromagnetic shielding cavity, which houses the controller. It can effectively block strong electromagnetic interference from the outside of the second housing 15 from entering the inside of the second housing 15 and intruding into the controller. At the same time, it can also prevent the interference of the controller itself from radiating from the inside of the second housing 15 to the outside of the second housing 15.

[0044] In some possible implementations, refer to Figure 3 The second housing 15 is connected to the outer side of the first housing 10. The first housing 10 has a through hole (not shown in the figure) for the resolver harness 123 to pass through.

[0045] It is worth noting that in related technologies, the resolver sensor 12 is typically positioned at the rear end of the hybrid enclosure 1. The resolver rotor 122 of the resolver sensor 12 is mounted at the rear end of the motor shaft 111, and the resolver stator 121 of the resolver sensor 12 is fixed to the rear cover of the hybrid enclosure 1. The resolver harness 123 extends out from the rear cover. It should be noted that since the resolver harness 123 extends out from the rear cover, a hole must be drilled in the rear cover of the hybrid enclosure 1 to allow it to pass through. This structure significantly compromises the integrity of the overall shielding of the hybrid enclosure 1, resulting in the hybrid enclosure 1's EMC (Electromagnetic Compatibility) only reaching a maximum of CLASS 3. This is a passable level under moderate interference conditions, meaning the hybrid enclosure 1 can maintain its basic functions without being affected and does not cause serious interference to other devices in the same environment, but its emission margin is small and its immunity margin is not high.

[0046] Based on this, a through hole (not shown in the figure) can be opened on the side wall of the first housing 10. The through hole connects the inside of the first housing 10 and the inside of the second housing 15. The resolver harness 123 enters the inside of the second housing 15 from the inside of the first housing 10 through the through hole, so as to be electrically connected to the controller inside the second housing 15.

[0047] It is understandable that the through hole on the side wall of the first housing 10 directly connects to the interior of the second housing 15. Although the resolver harness 123 enters the interior of the second housing 15 through the through hole from the interior of the first housing 10, the resolver harness 123 is still inside the outer shell formed by the first housing 10 and the second housing 15, which is a larger area. In other words, compared with the related technology where a hole is drilled in the rear cover to allow the resolver harness 123 to pass through, which would damage the integrity of the overall shielding of the hybrid housing 1, the outer shell formed by the first housing 10 and the second housing 15 is a continuous and complete shielding. The resolver harness 123 is inside the outer shell, which ensures the integrity of the overall shielding of the hybrid housing 1 and can improve the EMC of the hybrid housing 1 to the CLASS4 level, thereby improving the EMC level of the hybrid housing 1.

[0048] In some possible implementations, the through hole connects to the second cavity 101.

[0049] The first housing 10 has a first cavity 100 and a second cavity 101. The first cavity 100 is used to accommodate the motor 11, and the second cavity 101 is used to accommodate the gear shaft 13. The rotating shaft 111 of the motor 11 is located in the second cavity 101 and is connected to the gear shaft 13. The resolver stator 121 of the resolver sensor 12 is fixed to the second cavity 101, and the resolver rotor 122 of the resolver sensor 12 is sleeved on the portion of the rotating shaft 111 located in the second cavity 101.

[0050] The resolver sensor 12 is arranged inside the second cavity 101, and the resolver harness 123 can enter the second housing 15 through the through hole and be electrically connected to the controller.

[0051] In some possible examples, a shielding bushing (not shown in the figure) can be installed at the through-hole. The resolver harness 123 passes through the shielding bushing and presses the shielding bushing against the edge of the through-hole formed by the first housing 10, thereby achieving a relative seal between the interior of the first housing 10 and the interior of the second housing 15, and also ensuring the continuity of the shielding.

[0052] In some possible implementations, refer to Figure 3 and Figure 4 The resolver stator 121 is connected to the first housing 10.

[0053] The resolver stator 121 can be connected to the inner wall of the second cavity 101 formed by the first housing 10, which can fix the resolver stator 121 without the use of an additional fixing mechanism, saving the space occupied by fixing the resolver stator 121 inside the second cavity 101.

[0054] In some possible implementations, the hybrid housing 1 also includes a pressure plate (not shown) that presses the resolver rotor 122 onto the front end of the shaft 111.

[0055] The pressure plate can securely mount the resolver rotor 122 to the front end of the shaft 111.

[0056] In some possible implementations, refer to Figure 3 and Figure 6 There are two motors 11 and two resolver stators 121. The two motors 11 are spaced apart, and the two resolver sensors 12 are respectively arranged at the front end of the rotating shaft 111 of the two motors 11.

[0057] For example, one of the motors 11 can be a drive motor 11, and the shaft 111 of the drive motor 11 can be connected to the gear shaft 13. The other motor 11 can be a generator 11. The two resolver sensors 12 are used to detect the angular position, speed and direction of rotation of the shafts 111 of the two motors 11, respectively.

[0058] Both motors 11 can be housed within the first cavity 100 of the first housing 10, and the shafts 111 of both motors 11 can extend into the second cavity 101 of the first housing 10. It is understood that the portions of the shafts 111 extending into the second cavity 101 are not located on the axial critical dimension chain path of the hybrid housing 1. Therefore, by arranging the two resolver sensors 12 at the front ends of the shafts 111 of the two motors 11, the axial critical dimension chain path of the hybrid housing 1 is avoided. Compared to arranging the resolver rotor 122 of the resolver sensor 12 at the rear end of the shafts 111 of the motors 11, this effectively compresses the axial dimension of the hybrid housing 1, thus reducing its volume.

[0059] This disclosure also provides a hybrid power system, including the hybrid box 1 as described above.

[0060] This disclosure also provides a vehicle including the above-described hybrid power system.
