Description

Technical Field

[0001] This utility model relates to the technical field of differential accessories, specifically a locking differential connecting gear. Background Technology

[0002] The locking differential connecting gear is a key component of an automotive transmission system, primarily used to achieve the locking function of the differential, thereby improving the vehicle's passability and stability in complex road conditions. The differential's role is to allow the left and right drive wheels to rotate at different speeds when the vehicle is turning, thus preventing tire slippage and wear.

[0003] A search revealed Chinese patent publication number CN217301501U, which discloses a connecting gear, including a mounting shaft. The mounting shaft has an external thread, a slot on its outer periphery, and a mounting groove inside. A baffle is welded to one end of the mounting shaft, and a gear piece is slidably mounted on its exterior. The two slots, symmetrically positioned on the upper and lower sides of the mounting shaft, facilitate the engagement and fixation of the gear piece and connecting piece to the outside of the mounting shaft, enabling easy assembly and disassembly. The nut piece has an internal thread, which is matched by the external thread of the mounting shaft, allowing for the installation and fixing of different numbers of gear pieces and connecting pieces. The width of the gear can be adjusted by installing different numbers of gear pieces and connecting pieces to accommodate more gears, thus improving gear adaptability.

[0004] However, while this device has advantages in gear width adjustment and simple assembly, it has significant shortcomings in terms of rapid and accurate replacement, improved maintenance efficiency, and wide applicability. Its structural design has not completely resolved the deficiencies in convenience and flexibility of existing devices and requires further optimization to achieve greater practicality and economy. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a locking differential connecting gear, which solves the problems of existing devices lacking convenient rack replacement function and wide applicability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a locking differential connecting gear, comprising a mounting ring, a rack, and a first rim. The rack is located within the first rim, and a mounting ring is located on one side of the first rim. The first rim has multiple mounting grooves arranged in a circumferential array. A guide rail is located within the mounting groove, and a rack is located within the guide rail. The rack has a groove that engages with the guide rail. The rack is made of high-strength alloy steel and undergoes heat treatment to improve its wear resistance and fatigue resistance. The groove of the rack and the engaging part with the guide rail have a lubricating coating to reduce friction and wear.

[0007] When using this device, first apply lubricant to the guide rail in the mounting slot, then align the groove of the rack with the guide rail in the mounting slot and insert it. Next, align the through hole of the mounting ring with the threaded hole of the lower rim and fit it in place. Select a bolt that matches the diameter and depth of the threaded hole, and rotate the bolt through the through hole into the threaded hole. When the nut is subjected to a large frictional force from the limiting washer, the rack installation is complete. When the rack becomes worn or corroded after long-term use, rotate the bolt out of the through hole, find the worn or corroded rack, replace it, and then repeat the above rack installation steps to complete the precise replacement of the rack. Traditional gears require the entire gear to be replaced after the rack is damaged or corroded, resulting in high maintenance costs. However, this design, through the modular rack design, allows for the individual replacement of the rack, greatly reducing maintenance costs. Depending on the different transmission gears connected, the meshing rack can be replaced according to the shape, size, and arrangement of the teeth of the transmission gear, realizing the versatility of this device. This design allows the device to adapt to different transmission needs, improving its application range and flexibility.

[0008] Preferably, one side of the first wheel rim is provided with multiple threaded holes arranged in a circumferential array. The inner wall of the threaded holes has anti-loosening threads to prevent the bolts from loosening under vibration. The depth and diameter of the threaded holes are optimized according to the specifications of the mounting bolts to ensure the firmness of the connection.

[0009] Preferably, the lower outer wall of the mounting ring is provided with a plurality of limiting blocks arranged in a circular array. The shape of the limiting blocks is the same as the cross-sectional shape of the guide rail in the mounting groove and they fit together. The number of limiting blocks is the same as the number of mounting grooves and they correspond one to one. The side of the limiting blocks has a guide slope to facilitate the quick alignment and installation of the mounting ring and the first wheel rim. The material of the limiting blocks is wear-resistant engineering plastic, which can reduce friction and wear with the guide rail.

[0010] Preferably, the mounting ring has multiple through holes arranged in a circumferential array. A limiting washer is provided at one end of each through hole. The number of through holes is the same as the number of threaded holes and they correspond one-to-one. The limiting washer is made of spring steel, which has a high elastic modulus to ensure the preload of the bolt. The diameter of the through hole is slightly larger than the bolt diameter to facilitate the insertion and adjustment of the bolt.

[0011] Preferably, the inner wall of the first wheel rim is fixedly connected with three spokes arranged in a circular array. One end of the spokes is fixedly connected to the first wheel hub. The connection between the spokes and the first wheel hub is provided with reinforcing ribs, which improves the strength and rigidity of the overall structure. The spokes are made of lightweight and high-strength composite materials to reduce the overall weight of the gear.

[0012] Preferably, the second hub has an axle hole, and the inner wall of the axle hole is precision machined and surface treated to improve wear resistance and corrosion resistance.

[0013] This utility model provides a locking differential connecting gear. It has the following advantages:

[0014] 1. This locking differential connecting gear, through its modular design, allows for the individual replacement of the rack, avoiding the high cost of replacing the entire gear when the rack is damaged, as is common with traditional gears. The interlocking design between the rack and the guide rail, along with the limiting block and through-hole structure of the mounting ring, makes the rack removal and installation more precise and convenient. The use of lubricating coating and lubricant reduces friction and extends the rack's service life. This design significantly improves maintenance efficiency and reduces maintenance costs, making it particularly suitable for equipment used frequently and under harsh conditions.

[0015] 2. This locking differential connecting gear allows the rack to be customized and replaced according to the needs of different transmission gears, adapting to transmission gears with different tooth shapes, sizes, and arrangements. The universal design of the mounting groove and mounting ring on the first rim enables the gear to quickly adapt to various transmission systems. The spokes are made of lightweight, high-strength composite materials, reducing the overall weight while enhancing structural strength. This flexibility and adaptability allows the device to be widely used in various vehicles and mechanical equipment, improving its practicality and economy in different application scenarios.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-4 This utility model provides a locking differential connecting gear, including a mounting ring 12, a rack 2, and a first wheel rim 6. The rack 2 is disposed inside the first wheel rim 6, and the mounting ring 12 is disposed on one side of the first wheel rim 6. The first wheel rim 6 has a plurality of mounting grooves 4 arranged in a circumferential array. A guide rail 3 is disposed inside the mounting groove 4, and the rack 2 is disposed inside the guide rail 3. The rack 2 has a groove 1, which fits into the guide rail 3. In use, lubricant is first applied to the guide rail 3 in the mounting groove 4, and then the groove 1 of the rack 2 is aligned with the guide rail 3 in the mounting groove 4 and inserted. This design makes the installation and replacement of the rack 2 more convenient. At the same time, the use of the lubricating coating and lubricant effectively reduces the friction between the rack 2 and the guide rail 3, extending the service life of the gear.

[0025] Example 2

[0026] Please see Figure 1-4 In this embodiment, a plurality of threaded holes 5 arranged in a circumferential array are provided on one side of the first wheel rim 6. A bolt matching the diameter and depth of the threaded hole 5 is selected, and the bolt is rotated into the threaded hole 5 through the through hole 11 of the mounting ring 12 to complete the fixing of the mounting ring 12 on the wheel rim 6, and at the same time complete the installation and fixing of the rack 2.

[0027] The lower outer wall of the mounting ring 12 is provided with a plurality of limiting blocks 10 arranged in a circular array. The shape of the limiting blocks 10 is the same as the cross-sectional shape of the guide rail 3 in the mounting groove 4 and they fit together. The number of limiting blocks 10 and the mounting groove 4 are the same and correspond one-to-one. In use, after the limiting blocks 10 of the mounting ring 12 are aligned with the mounting groove 4 of the first wheel rim 6, the guide slope of the limiting blocks 10 makes the installation process smoother, reduces the installation time and difficulty, and the use of wear-resistant engineering plastic further reduces the friction between the limiting blocks 10 and the guide rail 3, improving the reliability of the gear.

[0028] The mounting ring 12 has multiple through holes 11 arranged in a circular array. One end of each through hole 11 is provided with a limiting washer 13. The number of through holes 11 is the same as the number of threaded holes 5 and they correspond one-to-one. In use, when the bolt is rotated into the threaded hole 5 through the through hole 11, the limiting washer 13 provides sufficient preload to ensure the firmness of the bolt connection. The design of the through hole 11 having a diameter slightly larger than the bolt diameter makes it easier to insert and adjust the bolt, thus improving installation efficiency.

[0029] The inner wall of the first wheel rim 6 is fixedly connected to three spokes 8 arranged in a circular array. One end of the spokes 8 is fixedly connected to the outer wall of the second wheel hub 9. In use, the design of the spokes 8 not only enhances the structural strength of the gear, but also reduces the weight of the gear by using lightweight and high-strength composite materials, thereby reducing the load on the transmission system and improving the vehicle's fuel efficiency and power performance.

[0030] The second hub 9 has a shaft hole 7 inside. During use, the high-precision machining and surface treatment of the shaft hole 7 ensure a tight fit with the drive shaft, reducing wear and corrosion and extending the service life of the gear. The design of the shaft hole 7 also facilitates the installation and disassembly of the drive shaft, improving maintenance efficiency.

[0031] It should be noted that, in this embodiment, when using this device, first apply lubricant to the guide rail 3 in the mounting groove 4, then align the groove 1 of the rack 2 with the guide rail 3 in the mounting groove 4 and insert it. Then, align the through hole 11 of the mounting ring 12 with the threaded hole 5 of the lower first rim 6 and fit it in place. Select a bolt that matches the diameter and depth of the threaded hole 5, and rotate the bolt through the through hole 11 into the threaded hole 5. When the nut is subjected to a large frictional force from the limiting washer 13, the installation of the rack 2 is completed. When the rack 2 is worn or corroded after long-term use, rotate the bolt out of the through hole 11 and find the worn area. The rack 2 can be replaced if it is damaged or corroded, and then the rack installation steps described above can be performed to complete the precise replacement of rack 2. Traditional gears require the entire gear to be replaced after the rack is damaged or corroded, which is too costly to maintain. However, this design achieves the individual replacement of rack 2 through the modular design of rack 2, which greatly reduces maintenance costs. Depending on the transmission gears connected, the meshing rack 2 can be replaced according to the shape, size and arrangement of the teeth of the transmission gear, realizing the versatility of this device. This design enables the device to adapt to different transmission needs and improves its application range and flexibility.
