Description

Technical Field

[0001] This disclosure relates to the field of transmission technology, and particularly to a housing structure, a hybrid transmission, and a vehicle. Background Technology

[0002] Compared to traditional transmissions, hybrid transmissions have a higher degree of electronic integration due to the use of important components such as electric motors and motor controllers. Electromagnetic compatibility (EMC) has become a crucial performance indicator for hybrid transmissions. The resolver is a vital electronic component in the motor controller, primarily used to accurately measure the rotor's position, speed, and direction of rotation.

[0003] In related technologies, for ease of installation, the rotary transformer is often mounted on the rear cover on the side of the motor away from the transmission components. This forces the rotary transformer's wiring harness to pass through the rear cover and out of the entire gearbox to connect with the vehicle's wiring harness, resulting in external wiring harnesses and connectors, which affects the horizontal stability of the hybrid transmission. Furthermore, this arrangement of the rotary transformer also increases the axial dimension of the hybrid transmission, hindering the reduction of the overall gearbox size. Summary of the Invention

[0004] Therefore, this disclosure provides a housing structure, a hybrid power transmission, and a vehicle, which can reduce the axial dimension of the hybrid power transmission and improve its EMC level. The technical solution is as follows:

[0005] In a first aspect, a shell structure is provided, the shell structure including a main shell, the main shell including a partition structure; The partition structure is used to divide the internal space of the main housing into a motor room, a gear room, and a controller room, wherein the gear room is adjacent to both the motor room and the controller room; The partition structure includes a first partition and a second partition, wherein the first partition is used to separate the gear chamber from the motor chamber, and the second partition is used to separate the gear chamber from the controller chamber; The first partition has a resolver stator mounting groove on the side facing the motor chamber. The first partition has a shaft hole and a first wire harness through hole. Both the shaft hole and the first wire harness through hole pass through the gear chamber and the motor chamber. The resolver stator mounting groove is annular and coaxially surrounds the shaft hole. The second partition has a second wiring harness through-hole, which passes through the gear chamber and the controller chamber.

[0006] In some possible implementations, the first partition is further provided with a bearing mounting groove on the side facing the motor chamber. The resolver stator mounting groove and the bearing mounting groove are arranged in annular steps. The bearing mounting groove is coaxially surrounding the shaft hole, and the outer diameter of the bearing mounting groove is smaller than the outer diameter of the resolver stator mounting groove.

[0007] In some possible implementations, a wire harness fixing structure is provided on the side of the first partition facing the motor chamber, and / or, a wire harness fixing structure is provided on the side of the first partition facing the gear chamber.

[0008] In some possible implementations, the partition structure further includes a third partition for separating the motor compartment from the controller compartment.

[0009] In some possible implementations, the motor compartment, the gear compartment, and the controller compartment are all open; The housing structure includes a motor rear cover, a gear cover, and a controller upper housing. The motor rear cover is detachably installed in the opening of the motor chamber to close the motor chamber. The gear cover is detachably installed in the opening of the gear chamber to close the gear chamber. The controller upper housing is detachably installed in the opening of the controller chamber to close the controller chamber.

[0010] In a second aspect, a hybrid power transmission is provided, the hybrid power transmission comprising the housing structure, rotary transformer, motor and controller described in any of the first aspects; The rotary transformer and the motor are both installed in the motor compartment of the housing structure, and the controller is installed in the controller compartment of the housing structure; The output shaft of the motor passes through the shaft hole of the housing structure into the gear chamber of the housing structure; The resolver stator of the rotary transformer is mounted on the first partition of the housing structure through the resolver stator mounting slot of the housing structure; The resolver rotor of the resolver is fixedly mounted on the output shaft and located inside the resolver stator. The first end of the resolver harness of the resolver is connected to the resolver stator, and the second end of the resolver harness passes through the first harness through hole to the gear chamber and is connected to the controller through the second harness through hole.

[0011] In some possible implementations, the controller includes a socket that is mounted in the second wiring harness through-hole; The second end of the resolver harness has a plug that is inserted into the socket to connect the resolver harness to the controller.

[0012] In some possible implementations, when the first partition is provided with a bearing mounting groove, a shaft bearing is sleeved on the output shaft, and the shaft bearing is assembled in the bearing mounting groove; Preferably, the hybrid power transmission further includes a magnetic shielding plate; The magnetic shielding plate covers the surface of the resolver stator and is located on the side of the resolver stator away from the first partition. The magnetic shielding plate is annular so that the output shaft can pass through the inside of the magnetic shielding plate.

[0013] In some possible implementations, when the first partition is provided with a wire harness fixing structure, the resolver wire harness is fixed to the side corresponding to the first partition by the wire harness fixing structure.

[0014] Thirdly, a vehicle is provided, the vehicle comprising a hybrid transmission as described in any of the second aspects.

[0015] In the scheme disclosed herein, the resolver stator mounting slot on the first partition can be used to install the resolver stator of the resolver. The resolver rotor of the resolver can be fixedly mounted on the output shaft, located inside the resolver stator. This allows the resolver to be located within the gap between the motor and the transmission assembly, without occupying additional space, thus reducing the axial dimension of the hybrid transmission. Simultaneously, the resolver wiring harness can pass through the first wiring harness through-hole to the gear chamber, and through the second wiring harness through-hole to connect to the controller in the controller chamber. Finally, it can be connected to the vehicle wiring harness through the controller's low-voltage connector. This prevents the resolver wiring harness from being exposed outside the housing structure, thereby reducing the possibility of electromagnetic interference and improving the EMC level of the hybrid transmission.

[0019] 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.

[0020] Firstly, this embodiment relates to a shell structure, as shown in the reference... Figure 1 and Figure 2 As shown, the shell structure includes a main shell 1, and the main shell 1 includes a partition structure 11. The main shell 1 can be integrally formed, which helps reduce assembly complexity, improve assembly efficiency, and enhance integration.

[0021] Combination Figure 3 , Figure 4 and Figure 7 As shown, the partition structure 11 is used to divide the internal space of the main housing 1 into a motor chamber 101, a gear chamber 102, and a controller chamber 103, wherein the gear chamber 102 is adjacent to both the motor chamber 101 and the controller chamber 103. As shown in the figure... Figure 4 and Figure 5 As shown, the motor compartment 101 can be used to install the motor 300, the gear compartment 102 can be used to install the transmission gear set, and the controller compartment 103 can be used to install the controller 400.

[0022] Combination Figure 1 and Figure 7 As shown, the partition structure 11 includes a first partition 111 and a second partition 112. (Combined) Figure 1 , Figure 2 and Figure 4 As shown, the first partition 111 is used to separate the gear chamber 102 from the motor chamber 101. (Combined) Figure 2 and Figure 4 As shown, the second partition 112 is used to separate the gear chamber 102 and the controller chamber 103.

[0023] refer to Figure 1 As shown, the first partition 111 has a resolver stator mounting groove 1111 on the side facing the motor chamber 101. The first partition 111 has a shaft hole 1112 and a first wire harness through hole 1113. Both the shaft hole 1112 and the first wire harness through hole 1113 pass through the gear chamber 102 and the motor chamber 101. The resolver stator mounting groove 1111 is annular and coaxially surrounds the shaft hole 1112.

[0024] Thus, the output shaft 31 of the motor 300 installed in the motor chamber 101 can pass through the shaft hole 1112 into the gear chamber 102 and be connected to the transmission gear set in the gear chamber 102 to realize power output. The resolver stator mounting slot 1111 on the first partition 111 can be used to install the annular resolver stator 21 of the resolver 200. The resolver rotor 22 of the resolver 200 can be fixedly mounted on the output shaft 31. After the output shaft 31 of the motor 300 passes through the shaft hole 1112 of the housing structure into the gear chamber 102 of the housing structure, the resolver rotor 22 can be located inside the resolver stator 21. When the output shaft 31 rotates, the resolver rotor 22 can rotate with it, thereby generating relative motion with the resolver stator 21, and thus the rotor angle and speed of the motor can be measured.

[0025] refer to Figure 4 and combined Figure 7 As shown, the second partition 112 has a second wiring harness through-hole 1121, which passes through the gear chamber 102 and the controller chamber 103. Thus, the resolver harness 23 of the resolver 200 can pass through the first wiring harness through-hole 1113 to the gear chamber 102, and then connect to the controller 400 in the controller chamber 103 via the second wiring harness through-hole 1121, achieving signal connection between the controller 400 and the resolver 200. Simultaneously, the motor 300 can also establish a signal connection with the controller 400. Therefore, the controller 400 can receive the motor rotor angle and speed signals transmitted by the resolver 200, and control the speed of the motor 300 using these signals.

[0026] As described above, the resolver stator mounting slot 1111 on the first partition 111 can be used to install the resolver stator 21, and the resolver rotor 22 can be fixedly mounted on the output shaft 31 and located inside the resolver stator 21. Thus, the resolver 200 can be located in the gap between the motor 300 and the transmission assembly without taking up extra space, thereby reducing the axial dimension of the hybrid power transmission.

[0027] Meanwhile, the resolver harness 23 of the resolver 200 can pass through the first harness through hole 1113 to the gear chamber 102, and connect to the controller 400 in the controller chamber 103 through the second harness through hole 1121. Finally, it can be connected to the vehicle harness through the low-voltage connector of the controller 400, so that the resolver harness 23 will not be exposed outside the housing structure, thereby reducing the possibility of electromagnetic interference and improving the EMC level of the hybrid transmission.

[0028] In some examples, reference Figure 5 , Figure 6 and Figure 7 and combined Figure 1 As shown, the first partition 111 is also provided with a bearing mounting groove 1114 on the side facing the motor chamber 101. The resolver stator mounting groove 1111 and the bearing mounting groove 1114 are arranged in annular stepped distribution. The bearing mounting groove 1114 is coaxially arranged around the shaft hole 1112, and the outer diameter of the bearing mounting groove 1114 is smaller than the outer diameter of the resolver stator mounting groove 1111.

[0029] The bearing mounting groove 1114 can be used to mount the rotating shaft bearing 311. Since the outer diameter of the bearing mounting groove 1114 is smaller than the outer diameter of the resolver stator mounting groove 1111, that is, in combination with... Figure 5 and Figure 6 As shown, the resolver stator mounting slot 1111 is located between the bearing mounting slot 1114 and the motor 300, thus the resolver rotor 22 can be located between the motor 300 and the shaft bearing 311. Therefore, the resolver rotor 22 can be first mounted on the output shaft 31, forming a single unit with the output shaft 31, and then the shaft bearing 311 and the output shaft 31 can be assembled. In this way, the output shaft 31 and the resolver rotor 22 can be installed together in the motor housing 101, thus simplifying the assembly process and improving assembly efficiency. Furthermore, the output shaft 31 can be rotatably connected to the first partition 111 via the shaft bearing 311, while simultaneously allowing the resolver rotor 22 to be located inside the resolver stator 21, enabling the measurement of the motor rotor angle and speed.

[0030] In some examples, reference Figure 1As shown, a wire harness fixing structure 1115 is provided on the side of the first partition 111 facing the motor compartment 101. For example, the wire harness fixing structure 1115 can be a cable tie, a clip, etc. The wire harness fixing structure 1115 can be fixedly installed on the first partition 111 by means of bolts, welding, or snap-fit. In this way, the wire harness fixing structure 1115 can fix the resolver wire harness 23, preventing the resolver wire harness 23 from shaking inside the housing structure and generating noise, or even affecting the service life of the resolver wire harness 23.

[0031] In some examples, a wire harness fixing structure 1115 is provided on the side of the first partition 111 facing the gear chamber 102. For example, the wire harness fixing structure 1115 can be a cable tie, a clip, etc. The wire harness fixing structure 1115 can be fixedly installed on the first partition 111 by means of bolts, welding, or snap-fit. In this way, the wire harness fixing structure 1115 can fix the resolver wire harness 23, preventing the resolver wire harness 23 from shaking and generating noise within the housing structure, or even affecting the service life of the resolver wire harness 23.

[0032] In some examples, to ensure reliable fixation of the resolver harness 23 on the first partition 111, the number of harness fixing structures 1115 on each side of the first partition 111 can be multiple, for example, two, three, four, or five. Specifically, the number of harness fixing structures 1115 on each side of the first partition 111 can be selected according to the length of the resolver harness 23 on each side. Specifically, a harness fixing structure 1115 can be provided every 2cm to 4cm depending on the length of the resolver harness 23. For example, one harness fixing structure 1115 can be provided every 2cm of the resolver harness 23. Another example is that one harness fixing structure 1115 can be provided every 2.5cm of the resolver harness 23. Yet another example is that one harness fixing structure 1115 can be provided every 3.5cm of the resolver harness 23.

[0033] In some examples, reference Figure 4 and Figure 5 As shown, the partition structure 11 also includes a third partition 113, which separates the motor compartment 101 from the controller compartment 103. For example, the partition structure 11 can be a Y-shaped or T-shaped partition, dividing the internal space of the main housing 1 into three adjacent chambers to form the motor compartment 101, gear compartment 102, and controller compartment 103, respectively. This arrangement of adjacent chambers improves the integration of the hybrid transmission and avoids excessively large hybrid transmissions that would waste space.

[0034] In some examples, reference Figure 1 and Figure 2As shown, the motor compartment 101, gear compartment 102, and controller compartment 103 are all open. (Reference) Figure 5 As shown, the housing structure includes a motor rear cover 2, a gear cover 3, and a controller upper housing 4. The motor rear cover 2 is detachably installed in the opening of the motor chamber 101 to close the motor chamber 101, the gear cover 3 is detachably installed in the opening of the gear chamber 102 to close the gear chamber 102, and the controller upper housing 4 is detachably installed in the opening of the controller chamber 103 to close the controller chamber 103.

[0035] For example, the motor rear cover 2 can be fixedly installed in the opening of the motor chamber 101 by means of bolts, snap-fit, etc. The gear cover 3 can be fixedly installed in the opening of the gear chamber 102 by means of bolts, snap-fit, etc. The controller upper housing 4 can be fixedly installed in the opening of the controller chamber 103 by means of bolts, snap-fit, etc.

[0036] Thus, the open motor compartment 101 facilitates the installation of the motor 300 and the resolver 200 within it; the open gear compartment 102 facilitates the connection of the resolver harness 23 to the controller 400 and the installation of the transmission gear set within it; and the open controller compartment 103 facilitates the installation of the controller 400 within it. Simultaneously, the motor rear cover 2 allows for the enclosure of the motor compartment 101, the gear cover 3 allows for the enclosure of the gear compartment 102, and the controller upper housing 4 allows for the enclosure of the controller compartment 103, which helps reduce electromagnetic interference and improve EMC levels.

[0037] In this embodiment of the present disclosure, the resolver stator mounting groove 1111 on the first partition 111 can be used to install the resolver stator 21, and the resolver rotor 22 can be fixedly mounted on the output shaft 31 and located inside the resolver stator 21. Thus, the resolver 200 can be located in the gap between the motor 300 and the transmission assembly without occupying additional space, thereby reducing the axial dimension of the hybrid power transmission.

[0038] Meanwhile, the resolver harness 23 of the resolver 200 can pass through the first harness through hole 1113 to the gear chamber 102, and connect to the controller 400 in the controller chamber 103 through the second harness through hole 1121. Finally, it can be connected to the vehicle harness through the low-voltage connector of the controller 400, so that the resolver harness 23 will not be exposed outside the housing structure, thereby reducing the possibility of electromagnetic interference and improving the EMC level of the hybrid transmission.

[0039] Secondly, refer to Figures 4 to 6 As shown, this embodiment provides a hybrid power transmission, which includes a housing structure according to any of the first aspects, a rotary transformer 200, a motor 300, and a controller 400.

[0040] like Figure 4 As shown, the rotary transformer 200 and the motor 300 are both installed in the motor compartment 101 of the housing structure, and the controller 400 is installed in the controller compartment 103 of the housing structure. The output shaft 31 of the motor 300 passes through the shaft hole 1112 of the housing structure into the gear compartment 102 of the housing structure. The resolver stator 21 of the rotary transformer 200 is installed on the first partition 111 of the housing structure through the resolver stator mounting slot 1111 of the housing structure. The resolver rotor 22 of the rotary transformer 200 is fixedly mounted on the output shaft 31 and located inside the resolver stator 21. Figure 1 As shown, the first end of the resolver harness 23 of the resolver 200 is connected to the resolver stator 21, and the second end of the resolver harness 23 passes through the first harness through hole 1113 to the gear chamber 102, and is connected to the controller 400 through the second harness through hole 1121.

[0041] As described above, the resolver stator mounting slot 1111 on the first partition 111 can be used to install the resolver stator 21 of the resolver 200. The resolver rotor 22 of the resolver 200 can be fixedly mounted on the output shaft 31, located inside the resolver stator 21. Thus, the resolver 200 can be located within the gap between the motor 300 and the transmission assembly, without occupying additional space, thereby reducing the axial dimension of the hybrid transmission. Simultaneously, the resolver harness 23 of the resolver 200 can pass through the first harness through-hole 1113 to the gear chamber 102, and through the second harness through-hole 1121 to connect to the controller 400 in the controller chamber 103. Finally, it can be connected to the vehicle wiring harness through the low-voltage connector of the controller 400, ensuring that the resolver harness 23 is not exposed outside the housing structure, thereby reducing the possibility of electromagnetic interference and improving the EMC level of the hybrid transmission.

[0042] In some examples, reference Figure 4 As shown, the controller 400 includes a socket 41, which is mounted in the second wiring harness through-hole 1121. For example, one end of the socket 41 can be connected to the controller body via a wiring harness, and the other end can have a socket facing the gear chamber 102. The socket 41 can be fixedly connected to the second partition 112 by bolts, welding, adhesive, or other means.

[0043] Continue to refer to Figure 4 As shown, the second end of the resolver harness 23 has a plug 231, which is plugged into the socket 41 to connect the resolver harness 23 to the controller 400.

[0044] Thus, the socket 41 of the controller 400 is located in the second wiring harness through hole 1121 of the second partition 112, which facilitates the connection between the resolver harness 23 and the controller 400, and at the same time improves the stability of the connection between the resolver harness 23 and the controller 400.

[0045] In some examples, when the first partition 111 is provided with a bearing mounting groove 1114, a shaft bearing 311 is fitted onto the output shaft 31, and the shaft bearing 311 is assembled in the bearing mounting groove 1114. In this way, the output shaft 31 can achieve rotational engagement with the first partition 111 through the shaft bearing 311.

[0046] For example, the shaft bearing 311 can be installed in the bearing mounting groove 1114, and the outer ring of the shaft bearing 311 can be interference-fitted with the bearing mounting groove 1114. The resolver stator 21 of the rotary transformer 200 can be fixedly installed in the resolver stator mounting groove 1111 by bolts. The motor stator of the motor 300 can be fixedly installed in the motor housing 101 by bolts. The motor rotor of the motor 300 can be sleeved and installed on the output shaft 31, with an interference fit. The resolver rotor 22 of the rotary transformer 200 can be press-fitted onto the output shaft 31 near the front end, with an interference fit. The front end of the output shaft 31 can pass sequentially through the resolver stator 21, the shaft bearing 311, and the shaft hole 1112 into the gear housing 102, so that the front end of the output shaft 31 can be rotatably engaged with the first partition 111 through the shaft bearing 311, while allowing the resolver rotor 22 to be located inside the resolver stator 21. The output shaft 31 and the inner ring of the shaft bearing 311 can be clearance-fitted or interference-fitted. The resolver harness 23 can pass through the first harness through hole 1113 and extend into the gear chamber 102. The motor rear cover 2 can be fixedly connected to the main housing 1 by bolts, snap-fit, etc., to close the opening of the motor chamber 101, and the rear end of the output shaft 31 can also be rotatably fitted with the motor rear cover 2 by a bearing to improve the rotational stability of the output shaft 31.

[0047] In some examples, reference Figure 6 and combined Figure 5 As shown, the hybrid transmission also includes a magnetic shielding plate 500. The magnetic shielding plate 500 covers the surface of the resolver stator 21 and is located on the side of the resolver stator 21 opposite to the first partition 111. The magnetic shielding plate 500 is annular so that the output shaft 31 can pass through the inside of the magnetic shielding plate 500.

[0048] The magnetic shielding plate 500 can be fixedly connected to the resolver stator 21 by bolts, snap-fit, or other means, or it can be fixedly connected to the first partition 111 by bolts, snap-fit, or other means, or it can be fixedly connected to both the resolver stator 21 and the first partition 111 by bolts.

[0049] For example, the resolver stator 21 can have multiple mounting holes spaced apart circumferentially. These mounting holes can be three, four, or five, etc. Similarly, the magnetic shielding plate 500 and the first partition 111 can also have corresponding mounting holes. Thus, bolts can be passed sequentially through the mounting holes in the magnetic shielding plate 500 and the corresponding mounting holes in the resolver stator 21, and finally screwed into the corresponding mounting holes in the first partition 111, which can be bolt holes. This allows for reliable fixing of the resolver stator 21 and the magnetic shielding plate 500 to the first partition 111.

[0050] In this way, the rotating stator 21 can be isolated from the motor stator of the motor 300 by the magnetic shielding plate 500, which helps to reduce electromagnetic interference between the rotary transformer 200 and the motor 300 and improve the EMC level of the hybrid power transmission.

[0051] In some examples, reference Figure 1 and Figure 2 As shown, when the first partition 111 is provided with a wire harness fixing structure 1115, the resolver wire harness 23 is fixed to the corresponding side of the first partition 111 by the wire harness fixing structure 1115. Thus, the resolver wire harness 23 can be fixed by the wire harness fixing structure 1115.

[0052] In some examples, combined Figure 1 and Figure 2 As shown, the first partition 111 can be provided with two shaft holes 1112, two first wire harness through holes 1113, and two resolver stator mounting slots 1111. The shaft holes 1112, first wire harness through holes 1113, and resolver stator mounting slots 1111 are all one-to-one corresponding, and the resolver stator mounting slots 1111 coaxially surround the corresponding shaft holes 1112. Therefore, two motors 300 and two corresponding resolvers 200 can be installed in the motor compartment 101. Figure 3 and Figure 4 As shown, the resolver harnesses 23 of the two resolvers 200 can be connected to the controller 400 through the same plug 231. This simplifies the wiring harness layout within the hybrid transmission, reducing the difficulty of assembly and subsequent maintenance.

[0053] In this embodiment of the present disclosure, the resolver stator mounting groove 1111 on the first partition 111 can be used to install the resolver stator 21, and the resolver rotor 22 can be fixedly mounted on the output shaft 31 and located inside the resolver stator 21. Thus, the resolver 200 can be located in the gap between the motor 300 and the transmission assembly without occupying additional space, thereby reducing the axial dimension of the hybrid power transmission.

[0054] Meanwhile, the resolver harness 23 of the resolver 200 can pass through the first harness through hole 1113 to the gear chamber 102, and connect to the controller 400 in the controller chamber 103 through the second harness through hole 1121. Finally, it can be connected to the vehicle harness through the low-voltage connector of the controller 400, so that the resolver harness 23 will not be exposed outside the housing structure, thereby reducing the possibility of electromagnetic interference and improving the EMC level of the hybrid transmission.

[0055] Thirdly, this embodiment provides a vehicle that includes any of the hybrid power transmissions described in the second aspect.

[0056] In this embodiment of the present disclosure, the resolver stator mounting groove 1111 on the first partition 111 can be used to install the resolver stator 21, and the resolver rotor 22 can be fixedly mounted on the output shaft 31 and located inside the resolver stator 21. Thus, the resolver 200 can be located in the gap between the motor 300 and the transmission assembly without occupying additional space, thereby reducing the axial dimension of the hybrid power transmission.

[0057] Meanwhile, the resolver harness 23 of the resolver 200 can pass through the first harness through hole 1113 to the gear chamber 102, and connect to the controller 400 in the controller chamber 103 through the second harness through hole 1121.
