Detailed Implementation

[0020] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0021] like Figure 1 As shown, a hydraulic serpentine spring coupling with built-in oil hole in one embodiment of the present invention includes a first hydraulic hub 7 and a second hydraulic hub 8. The outer end faces of the first hydraulic hub 7 and the second hydraulic hub 8 are fitted with a housing. Multiple fixing blocks 10 are fixedly connected to the outer end faces of the housing by welding. A second bolt 9 passes through the fixing block 10 and is threadedly connected to a nut 11 to fix the housing as a whole on the equipment.

[0022] like Figures 1 to 2As shown, multiple fixing components 6 are fixedly connected to a pair of opposite end faces of the outer shell. The outer shell includes a first outer shell 1 and a second outer shell 2. Multiple rotating components 5 are fixedly connected to the opposite end faces of the first outer shell 1 and the second outer shell 2, that is, the first outer shell 1 and the second outer shell 2 are rotatably connected through the rotating components 5, so that the first outer shell 1 and the second outer shell 2 can rotate relative to each other. The first outer shell 1 includes a first upper shell 101 and a first lower shell 102. The bottom end face of the first upper shell 101 is threadedly connected to the first lower shell 102 through a second bolt 9. The second outer shell 2 includes a second upper shell 201 and a second lower shell 202. The bottom end face of the second upper shell 201 is threadedly connected to the second lower shell 202 through a second bolt 9, forming a detachable structure. The user can remove one side of the outer shell as needed and flip it over by rotating components 5. The fixing components 6 temporarily fix it, without disassembling the whole.

[0023] like Figures 3 to 4 As shown, both the first outer shell 1 and the second outer shell 2 have receiving grooves 3 on their opposite end faces. The inner wall of the receiving groove 3 has multiple threaded holes 4 that match the first bolt 506 for threaded connection with the rotating assembly 5, allowing for the individual disassembly of one side of the outer shell, preventing the hydraulic hub on the other side from being exposed and reducing the risk of damage. The width of the receiving groove 3 does not exceed the thickness of the outer shell to prevent external dust and moisture from entering the interior of the outer shell through the receiving groove 3. The length of the receiving groove 3 is greater than the sum of the lengths of the pair of bases 503, and the depth of the receiving groove 3 is equal to or slightly greater than half the width of the connecting plate 5032, meaning that the base 503 is completely contained within the receiving groove 3, ensuring that the first outer shell 1 and the second outer shell 2 can fit tightly together, thereby providing protection.

[0024] like Figures 3 to 4 As shown, the rotating assembly 5 includes a rotating shaft 501, a pair of retaining rings 502, a pair of bases 503, and a plurality of first bolts 506. The rotating shaft 501 passes through the pair of bases 503. The retaining rings 502 are fixedly connected to a pair of opposite end faces of the rotating shaft 501, so that the bases 503 can rotate relative to the rotating shaft 501. A through hole 504 matching the first bolts 506 is provided on each pair of bases 503. The first bolts 506 pass through the through hole 504 and are threadedly connected to the threaded hole 4. The rotating assembly 5 is threadedly connected to the first housing 1 or the second housing 2, thereby fixing the rotating assembly 5 to the housing. The base 503 includes a fixing ring 5031 and a connecting plate 5032. The fixing ring 5031 is sleeved on the rotating shaft 501 and rotates on the rotating shaft 501. The connecting plate 5032 is fixedly connected to the fixing ring 5031. A mounting hole 505 is opened on one end face of the connecting plate 5032. The depth of the mounting hole 505 matches the head of the first bolt 506, that is, the head of the first bolt 506 does not protrude from the surface of the base 503, so that the opposite end faces of the first outer shell 1 and the second outer shell 2 can fit tightly together, avoid interference, and protect the hydraulic hub from external environmental interference.

[0025] Specifically, the user aligns the connecting plate 5032 on one of the bases 503 with the threaded hole 4 on the first outer shell 1, so that the first bolt 506 passes through the through hole 504 and the threaded hole 4 in sequence and is threadedly connected to the first upper shell 101. Then, multiple first bolts 506 pass through the through hole 504 on another connecting plate 5032 and the threaded hole 4 on the second upper shell 201 in sequence and are threadedly connected to the second upper shell 201, ensuring that the head of the first bolt 506 does not protrude from the connecting plate 5032, thereby fixing the rotating component 5 on both the first upper shell 101 and the second upper shell 201 at the same time, so that the first upper shell 101 or the first lower shell 102 can rotate through the rotating component 5. Similarly, the rotating component 5 is rotatably connected between the first lower shell 102 and the second lower shell 202.

[0026] like Figures 5 to 6 As shown, the fixing component 6 includes a fixing pin 601, a pair of fixing parts 602, and a snap-fit ​​plate 603. The pair of fixing parts 602 are fixedly connected to a pair of opposite end faces of the outer shell by welding. Each of the fixing parts 602 has a fixing hole 6021. The fixing pin 601 passes through the fixing hole 6021 and snaps into the snap-fit ​​plate 603, facilitating disassembly, reducing the user's disassembly workload, and further shortening maintenance time. The fixing pin 601 has a pair of slots 6011, and the snap-fit ​​plate 603 has a pair of slot interfaces 6031 that match the fixing pin 601. The inner wall of each slot interface 6031 has multiple claws 6032 that match the slots 6011, achieving a firm snap-fit ​​and preventing the outer shell from rotating due to gravity or accidental contact, ensuring user safety. When a single wheel hub needs to be replaced, the user can temporarily fix the flipped outer shell using the snap-fit ​​structure of the fixing pin 601 and the snap-fit ​​plate 603, ensuring stability during operation.

[0027] Furthermore, a stop block is fixedly connected to the middle end face of the snap-fit ​​plate 603, located between a pair of fixing members 602, to support the first upper shell 101 and the second upper shell 201 or the first lower shell 102 and the second lower shell 202, to distribute the weight, and to prevent the weight of the shell itself from putting too much burden on the fixing pin 601.

[0028] Specifically, when a single hydraulic hub needs to be replaced, such as the first hydraulic hub 7, the user rotates the first upper shell 101 and the first lower shell 102 to a state opposite to the second upper shell 201 and the second lower shell 202 respectively via the rotating assembly 5. Then, the two ends of the fixing pin 601 pass through the fixing holes 6021 of a pair of fixing members 602 on the first upper shell 101 and the second upper shell 201 or the first lower shell 102 and the second lower shell 202 respectively, and are engaged with the locking plate 603 by the claw 6032, so that the first outer shell 1 is kept flipped. The user replaces the first hydraulic hub 7. After the replacement is completed, the first upper shell 101 and the first lower shell 102 are reset in sequence.

[0029] A hydraulic hub, wherein the hydraulic hub is the first hydraulic hub 7 as described in the above embodiment.

[0030] When using, such as Figures 1 to 2 As shown, when the first hydraulic hub 7 needs to be replaced, the user first removes the second bolt 9 and nut 11 used to fix the first housing 1, separating the first housing 1 from the equipment. It is then connected to the second housing 2 via the rotating assembly 5. Next, the user holds the first upper housing 101 and rotates it 180° using the rotating assembly 5, making it parallel to the first lower housing 102. The same applies to the first lower housing 102 and the second lower housing 202. The user inserts the fixing pin 601 through the fixing holes 6021 of a pair of fixing members 602 located on the first upper housing 101 and the second upper housing 201 or the first lower housing 102 and the second lower housing 202. Then, the user inserts the snap-fit ​​interface 603 of the snap-fit ​​plate 603. Align the end of the fixing pin 601 with the locking plate 603, push the locking plate 603 so that the locking claw 6032 is inserted into the locking groove 6011 of the fixing pin 601 to achieve temporary fixation, so that the first upper shell 101 and the first lower shell 102 are kept in the flipped state. At this time, the first hydraulic hub 7 is fully exposed, while the second hydraulic hub 8 is still wrapped by the second outer shell 2. The user can replace or maintain the first hydraulic hub 7. After the replacement is completed, remove the fixing pin 601 from the locking plate 603, pull out the fixing pin 601, and reset the first upper shell 101 and the first lower shell 102 by rotating the assembly 5 so that they are in contact with the second outer shell 2. Then reinstall the second bolt 9 and nut 11.
