Detailed Implementation

[0020] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0021] The following is for reference. Figures 1-5 A shaft mounting device 10 for a transmission according to an embodiment of the present invention is described.

[0022] like Figure 1 , Figure 2 , Figure 5As shown, according to a first aspect embodiment of the present invention, a shaft mounting device 10 for a transmission includes: a mounting housing 20 and a plurality of mounting bearings 30. The mounting housing 20 has a plurality of mounting grooves 21, which are located on the same side of the mounting housing 20 and open toward the same side of the mounting housing 20. The plurality of mounting grooves 21 are arranged sequentially along a first direction. The mounting housing 20 also has a communicating groove 22, which is provided between any two adjacent mounting grooves 21 and connects the corresponding two adjacent mounting grooves 21. The plurality of mounting bearings 30 are respectively mounted in the plurality of mounting grooves. Inside the mounting groove 21, the mounting bearing 30 is used to mount the shaft structure 40 of the transmission, and the first direction is perpendicular to the depth direction of the mounting groove 21; the oil guide plate 50 includes multiple oil pan parts 51, which are respectively disposed in multiple mounting grooves 21, and the oil pan parts 51 are located between the corresponding mounting bearing 30 and the bottom wall 211 of the corresponding mounting groove 21, and the oil pan parts 51 are in contact with the corresponding mounting bearing 30. The oil guide plate 50 also includes a limiting part 52, which is connected between any two adjacent oil pan parts 51 along the first direction, and the limiting part 52 is assembled in the corresponding connecting groove 22.

[0023] Among them, such as Figure 2 As shown, in this invention, the first direction is defined as the X direction, and the depth direction of the mounting groove 21 is defined as the Z direction. The mounting shell 20 can be made of materials such as gray cast iron or steel, and the mounting shell 20 can be formed by processes such as casting and forging. Figure 2 As shown, the mounting bearing 30 may include an inner bearing ring 31, a bearing roller 32, and an outer bearing ring 33. The mounting bearing 30 may be made of low-alloy, high-purity, integrally quenched chromium steel or similar materials, and may be formed through forging, heat treatment, and machining. The shaft mounting device 10 may include two, three, four, or other numbers of mounting bearings 30, such as... Figure 1 , Figure 2 As shown, the present invention will be described using the shaft mounting device 10, which includes two mounting bearings 30, as an example.

[0024] like Figure 2 As shown, a connecting groove 22 can be formed between the two mounting bearings 30. The mounting housing 20 can have two, three, four, or other mounting grooves 21, as shown. Figure 3 As shown, the present invention will be described using an example where the mounting housing 20 has two mounting grooves 21. As one embodiment, one mounting bearing 30 can be installed in one mounting groove 21. As an example, the shaft structure 40 can be installed on the mounting bearing 30 by a press-fit.

[0025] The oil guide plate 50 can be made of materials such as gray cast iron or steel, and can be formed by processes such as casting or forging. As one embodiment, one oil plate portion 51 can be installed in one mounting groove 21. Exemplarily, the limiting portion 52 can be integrally formed with two adjacent oil plate portions 51. As one embodiment, the limiting portion 52 can be interference-fitted with the corresponding connecting groove 22, so that the limiting portion 52 is tightly fitted to the inner wall of the corresponding connecting groove 22. As another embodiment, the inner wall of the connecting groove 22 can be provided with multiple positioning grooves, and the outer peripheral wall of the limiting portion 52 can be provided with multiple protruding positioning keys, and the multiple positioning keys can match the size and number of the multiple positioning grooves, so that the limiting portion 52 can be assembled into the corresponding connecting groove 22 by the cooperation of the positioning keys and the positioning grooves.

[0026] As an example, the mounting housing 20 may have a communicating groove 22. As another embodiment, the mounting housing 20 may have multiple communicating grooves 22. Figure 2 As shown, the present invention will be described using the example of a mounting shell 20 having a connecting groove 22.

[0027] The oil pan 51 is located between the bottom wall 211 of the corresponding mounting bearing 30 and the corresponding mounting groove 21. When the shaft structure 40 rotates at high speed, the outer ring 33 of the bearing can rotate slowly with the shaft structure 40. The limiting part 52 is assembled in the connecting groove 22. The inner side wall of the connecting groove 22 restricts the limiting part 52 from rotating, which helps to prevent the oil pan 51 from rotating. This reduces the risk of wear on the bottom wall 211 of the groove caused by the rotation of the oil pan 51, reduces the wear of the mounting shell 20, and thus helps to extend the service life of the shaft mounting device 10.

[0028] The limiting part 52 is assembled in the corresponding connecting groove 22 without occupying additional internal space of the transmission. This is beneficial to improving the structural compactness of the shaft mounting device 10, making the shaft mounting device 10 fit the compact layout requirements of the transmission under high pressure and high speed, and improving the internal space utilization of the transmission.

[0029] The limiting part 52 connects two adjacent oil pan parts 51, and the connecting groove 22 connects two adjacent mounting grooves 21. This facilitates the flow of lubricating oil in multiple mounting grooves 21 through the connecting groove 22, thereby reducing the problem of uneven lubrication caused by the layout of multiple mounting bearings 30. The oil guide plate 50 of the present invention has an integral structure. When assembling the oil guide plate 50, multiple oil pan parts 51 can be embedded into the corresponding multiple mounting grooves 21 at one time. At the same time, multiple limiting parts 52 can be simultaneously assembled into the corresponding multiple connecting grooves 22. There is no need to install each oil pan part 51 separately and additional fasteners. This reduces the assembly steps of the oil guide plate 50, reduces the assembly difficulty of the shaft mounting device 10, and thus improves the production efficiency of the shaft mounting device 10.

[0030] According to the first aspect of the present invention, the shaft mounting device 10, by providing an oil guide plate 50, does not rotate when the shaft structure 40 rotates at high speed, thereby reducing the wear of the mounting housing 20 and extending the service life of the shaft mounting device 10.

[0031] In some examples of embodiments of the present invention, such as Figure 2 , Figure 4 As shown, an oil storage space 70 is formed between the oil pan portion 51 and the bottom wall 211 of the corresponding mounting groove 21, and the oil pan portion 51 has a shaft lubrication hole 512 that communicates with the oil storage space 70.

[0032] The bottom wall 211 of the mounting groove 21 can be adapted to the oil pan portion 51, so that a closed oil storage space 70 is formed between the bottom wall 211 and the oil pan portion 51. As an example, at least a portion of the oil pan portion 51 is spaced apart from the bottom wall 211 of the corresponding mounting groove 21 to form the oil storage space 70.

[0033] As one embodiment, the shaft lubrication hole 512 can correspond to the center hole 41 of the shaft structure 40 along the depth direction of the mounting groove 21. The lubricating oil in the oil storage space 70 can flow into the center hole 41 of the shaft structure 40 through the shaft lubrication hole 512 to achieve lubrication of the shaft structure 40.

[0034] The oil reservoir 70 can be constructed as a closed structure, which helps to reduce the contact area between the lubricating oil and air, reduces the rate of oxidation and deterioration of the lubricating oil, reduces the risk of the lubricating oil being directly exposed to the impurities inside the transmission, reduces the risk of the lubricating oil being contaminated by impurities, and helps to extend the service life of the lubricating oil.

[0035] When the shaft structure 40 requires a large amount of lubricating oil, the lubricating oil in the oil storage space 70 can flow into the central hole 41 of the shaft structure 40 through the shaft lubrication hole 512, lubricating the interior of the shaft structure 40. When the shaft structure 40 requires less lubricating oil, the excess lubricating oil can flow back into the oil storage space 70 through the shaft lubrication hole 512, which helps to ensure a continuous supply of lubricating oil. The present invention forms an oil storage space 70 between the oil pan 51 and the bottom wall 211 of the groove, eliminating the need for additional oil storage and oil delivery components. This oil storage structure helps to reduce the number of parts in the shaft mounting device 10 and also helps to improve the structural compactness of the shaft mounting device 10.

[0036] In some examples of embodiments of the present invention, such as Figure 4 As shown, the circumferential edge of the oil pan portion 51 has a support shoulder 511 that protrudes toward the mounting bearing 30, and the support shoulder 511 contacts the outer ring 33 of the corresponding mounting bearing 30.

[0037] In one embodiment, when assembling and installing the bearing 30, the outer ring 33 of the bearing can be aligned with the support shoulder 511 without additional adjustment or calibration. This helps to reduce the assembly difficulty of installing the bearing 30, simplifies the installation process of the shaft mounting device 10, and further improves the installation efficiency of the shaft mounting device 10.

[0038] The support shoulder 511 contacts the outer ring 33 of the corresponding mounting bearing 30. The annular structure of the support shoulder 511 can constrain the offset of the outer ring 33 of the bearing in the circumferential direction, which helps to reduce the risk of the mounting bearing 30 being misaligned or displaced in the mounting groove 21, and also helps to reduce the risk of the mounting bearing 30 moving along the depth direction of the mounting groove 21, which helps to improve the structural stability of the shaft mounting device 10.

[0039] In some examples of embodiments of the present invention, such as Figure 2 , Figure 4 As shown, the shaft mounting device 10 also includes: a conductive brush 60, and a shaft lubrication oil pipe 513 is formed on the side of the oil pan portion 51 facing the corresponding mounting bearing 30. The shaft lubrication oil pipe 513 is arranged around the shaft lubrication hole 512 in the circumferential direction. The conductive brush 60 is sleeved on the shaft lubrication oil pipe 513. The conductive brush 60 is adapted to be assembled into the center hole 41 of the shaft structure 40 and adapted to contact the shaft structure 40.

[0040] In one embodiment, the conductive brush 60 can be interference-fitted onto the shaft lubrication oil pipe 513. Shaft current can sequentially pass through the shaft structure 40, the conductive brush 60, the oil guide plate 50, and the mounting housing 20 to form a conductive circuit, ensuring that the inner ring 31 and outer ring 33 of the mounting bearing 30 are at the same potential, thereby reducing electro-corrosion of the mounting bearing 30. For example, as... Figure 2 As shown, the inner wall of the central hole 41 of the shaft structure 40 is the inner wall 42 of the shaft.

[0041] Compared to traditional shaft mounting devices, the shaft mounting device 10 of the present invention is equipped with a conductive brush 60, which is sleeved on the shaft lubrication oil pipe 513. This eliminates the need for additional conductive supports, reducing the number of parts in the shaft mounting device 10, improving its structural compactness, and allowing it to fit within the compact space of the transmission. The conductive brush 60, fitted within the central hole 41 of the shaft structure 40, can contact the inner wall 42 of the shaft structure 40. Simultaneously, the frictional linear velocity of the conductive brush 60 is lower than that of the inner wall 42 of the shaft, thus reducing wear and increasing its service life.

[0042] The conductive brush 60 is suitable for assembly into the central hole 41 of the shaft structure 40 and for contact with the shaft structure 40. This eliminates the need for additional installation space for the conductive brush 60 at both ends of the shaft structure 40 along the depth direction of the mounting groove 21, thus reducing the installation space requirement of the shaft mounting device 10 along the depth direction of the mounting groove 21. After the conductive brush 60 is fitted onto the shaft lubrication oil pipe 513, the shaft lubrication oil pipe 513 can restrict the conductive brush 60 from moving in the direction perpendicular to the depth direction of the mounting groove 21, thereby helping to ensure stable contact pressure between the conductive brush 60 and the inner wall 42 of the shaft.

[0043] In some examples of embodiments of the present invention, such as Figure 2 , Figure 4 As shown, the conductive brush 60 includes an assembly part 61 and a plurality of contact parts 62. The assembly part 61 is sleeved on the shaft lubrication oil pipe 513. The plurality of contact parts 62 are disposed on the outer peripheral wall of the assembly part 61 and are arranged in sequence at intervals along the circumference of the assembly part 61. The contact parts 62 are adapted to contact the shaft structure 40.

[0044] The assembly part 61 can be made of materials such as brass or phosphor bronze, and can be formed by stamping or machining. The contact part 62 can be made of materials such as metal-graphite composite material or pure graphite brush material. As one embodiment, the outer peripheral wall of the assembly part 61 can be provided with multiple insert grooves along its circumference. The number of insert grooves can be equal to the number of contact parts 62, and the size of the insert grooves can match the size of the contact parts 62. The contact parts 62 can be inserted into the insert grooves by interference fit, and the outer surface of the contact parts 62 protrudes from the outer peripheral wall of the assembly part 61 and contacts the shaft structure 40. As another embodiment, the assembly part 61 and the multiple contact parts 62 can be a single unit.

[0045] The assembly part 61 of the conductive brush 60 is sleeved on the shaft lubrication oil pipe 513 of the oil pan part 51. Multiple contact parts 62 of the conductive brush 60 are arranged circumferentially around the assembly part 61 and contact the inner wall 42 of the shaft. The shaft current can sequentially pass through the shaft structure 40, the contact parts 62 of the conductive brush 60, the assembly part 61 of the conductive brush 60, the oil pan 50, and the mounting shell 20 to form a conductive circuit. This ensures that the inner ring 31 and outer ring 33 of the mounting bearing 30 are at the same potential, which helps to ensure conductive stability and further reduces the occurrence of electro-corrosion in the mounting bearing 30. The multiple contact parts 62 of the conductive brush 60 are arranged circumferentially around the assembly part 61. The contact parts 62 are adapted to contact the shaft structure 40, which allows multiple contact parts 62 to simultaneously contact the inner wall 42 of the shaft structure 40. Even if a single contact part 62 experiences poor contact, the other contact parts 62 can still maintain a conductive path, ensuring a continuous and stable output of the shaft current.

[0046] The conductive brush 60 is fitted onto the shaft lubrication oil pipe 513 via the assembly part 61. This arrangement helps to ensure that the linear velocity of the conductive brush 60 is consistent with the linear velocity of the inner wall 42 of the shaft, further reducing the frictional linear velocity of the conductive brush 60, thus reducing wear and increasing its service life. The assembly part 61, fitted onto the shaft lubrication oil pipe 513, simplifies the installation process of the conductive brush 60, improves the installation efficiency of the shaft mounting device 10, and enhances the structural compactness of the shaft mounting device 10.

[0047] In some examples of embodiments of the present invention, such as Figure 2 , Figure 4 As shown, the oil pan portion 51 also has a bearing lubrication hole 514 that communicates with the oil storage space 70. The bearing lubrication hole 514 and the corresponding mounting bearing 30 correspond to each other along the depth direction of the mounting groove 21.

[0048] The lubricating oil in the oil storage space 70 flows to the mounting bearing 30 through the bearing lubrication hole 514 to lubricate the mounting bearing 30. At the same time, the lubricating oil in the oil storage space 70 can also flow into the center hole 41 of the shaft structure 40 through the shaft lubrication hole 512 to lubricate the inside of the shaft structure 40.

[0049] The bearing lubrication hole 514 corresponds to the mounting bearing 30 along the depth direction of the mounting groove 21, which is beneficial to allow the lubricating oil in the oil storage space 70 to flow directly from the oil storage space 70 into the mounting bearing 30 along the bearing lubrication hole 514, thus ensuring the continuous lubrication of the mounting bearing 30 during operation.

[0050] The bearing lubrication hole 514 can concentrate the lubricating oil in the oil storage space 70 and guide it to the part of the bearing 30 that needs lubrication, eliminating the need for the lubricating oil to spread disorderly in the mounting groove 21 before contacting the bearing 30, thus reducing lubricating oil loss. The bearing lubrication hole 514 is formed on the oil pan portion 51, which helps to simplify the structural design of the shaft mounting device 10, thereby reducing the processing difficulty and cost of the shaft mounting device 10.

[0051] In some examples of embodiments of the present invention, such as Figure 4 As shown, there are multiple bearing lubrication holes 514, which are arranged sequentially along the circumference of the oil pan portion 51.

[0052] In one embodiment, multiple bearing lubrication holes 514 can be arranged sequentially and at intervals along the circumference of the oil pan portion 51. This arrangement of multiple bearing lubrication holes 514 along the circumference of the oil pan portion 51 allows for the simultaneous delivery of lubricating oil from different positions around the mounting bearing 30. This reduces the risk of insufficient lubrication in the mounting bearing 30 caused by a single lubrication hole 514 supplying lubricating oil, thus improving the operational stability of the mounting bearing 30. Furthermore, the multiple lubrication holes 514 reduce the risk of the mounting bearing 30 seizing or suffering severe wear due to interruption of lubricating oil delivery caused by blockage of a single lubrication hole 514, thereby enhancing the reliability of the shaft mounting device 10.

[0053] In some examples of embodiments of the present invention, at least one mounting groove 21 has an oil inlet hole formed on the bottom wall 211 of the groove, and the oil inlet hole is connected to the oil storage space 70 in the corresponding mounting groove 21.

[0054] In one embodiment, only one mounting groove 21 has an oil inlet hole formed on its bottom wall 211. In another embodiment, multiple mounting grooves 21 may each have an oil inlet hole formed on their bottom walls 211. As an example, one mounting groove 21 may have one oil inlet hole formed on its bottom wall 211. As another example, one mounting groove 21 may have multiple oil inlets formed on its bottom wall 211. Lubricating oil can enter the oil storage space 70 through the oil inlet hole.

[0055] The oil inlet hole is connected to the oil storage space 70 in the corresponding mounting groove 21, allowing lubricating oil to be directly introduced into the oil storage space 70. This shortens the lubricating oil delivery path, improves the efficiency of lubricating oil flowing into the oil storage space 70, and ensures sufficient lubricating oil in the oil storage space 70, thereby providing a continuous supply of lubricating oil to the shaft structure 40 and the mounting bearing 30. The oil inlet hole is directly formed on the bottom wall 211 of the mounting groove 21, eliminating the need for additional complex oil inlet channels and further enhancing the structural compactness of the shaft mounting device 10.

[0056] According to a second aspect of the present invention, the transmission includes: a plurality of shaft structures 40; a shaft mounting device 10, wherein the shaft mounting device 10 is the shaft mounting device 10 for the transmission described above, and the plurality of shaft structures 40 are respectively mounted on a plurality of mounting bearings 30.

[0057] As one example, such as Figure 1 , Figure 2As shown, multiple mounting bearings 30 are respectively sleeved on multiple shaft structures 40, and the multiple mounting bearings 30 correspond one-to-one with the multiple shaft structures 40. By setting the shaft mounting device 10 on the transmission, when the shaft structure 40 rotates at high speed, the oil guide plate 50 does not rotate, which helps to reduce the wear of the mounting housing 20, helps to extend the service life of the shaft mounting device 10, and thus helps to extend the service life of the transmission.

[0058] According to a third aspect embodiment of the present invention, the vehicle includes the transmission described above. By incorporating the transmission into the vehicle, it is beneficial to extend the vehicle's service life and enhance its market competitiveness.

[0059] The shaft mounting device 10 for a transmission, the transmission, and other components and operations of the vehicle according to embodiments of the present invention are known to those skilled in the art and will not be described in detail here.
