Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0028] During the use of large vehicles, the driving wheel will be worn and / or cracked, so it is necessary to disassemble and replace the driving wheel. In the related art, a sledgehammer is usually used to hit the driving wheel to separate the driving wheel and the reducer. This method makes the disassembly and replacement of the driving wheel inefficient and dangerous for workers.

[0029] Therefore, the embodiment of the present application provides a driving wheel disassembly device for a vehicle, which can remove the driving wheel without knocking the driving wheel, which can not only improve the efficiency of disassembly and replacement of the driving wheel but also is safer for workers.

[0030] The embodiments of the present application will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the driving wheel disassembly device provided in the embodiment of the present application. Figure 2 A partial cross-sectional view of a driving wheel disassembly device provided in an embodiment of the present application. As shown in the figure, the present embodiment provides a driving wheel disassembly device for a vehicle, comprising two screw rods 1, a jack 2 and a base 3, the top of each screw rod 1 is used to cooperate with the first threaded hole 101 on the reducer 10; the top of the jack 2 is used to extend into the pin shaft hole 102 on the reducer 10, and the top end is used to abut against the transmission shaft 201 of the driving wheel 20; the base 3 is provided with two second threaded holes 31 distributed at intervals, one second threaded hole 31 corresponds to the screw rod 1, the bottom of the screw rod 1 is cooperated with the corresponding second threaded hole 31, and the bottom end of the jack 2 abuts against the base 3.

[0032] In the driving wheel disassembly device provided in this embodiment, if the driving wheel 20 needs to be replaced, the bottom of the two screw rods 1 is first connected with the two second threaded holes 31, and then the screws at the two first threaded holes 101 of the reducer 10 are removed, and the top of the two screw rods 1 is connected with the two first threaded holes 101, and then the top and bottom of the jack 2 are respectively abutted against the transmission shaft 201 and the base 3, and the driving wheel 20 can be disassembled and replaced. In this way, the labor cost can be greatly reduced, and the safety of workers in the process of replacing and disassembling the driving wheel can be improved.

[0033] In some optional embodiments, the base 3 can be formed by waste channel steel on site to reduce the manufacturing cost of the driving wheel disassembly device provided in this embodiment. Moreover, in a specific implementation of this embodiment, the length of the base 3 is 60 cm. It should be noted that in other embodiments, the length of the base 3 can be determined according to the load-bearing capacity of the jack 2 and the size of the driving wheel 20, and no specific limitation is made here.

[0034] Please combine Figure 3 , Figure 3 A schematic diagram of the three-dimensional structure of the base in the driving wheel disassembly device provided in the embodiment of the present application. In a specific implementation of the present embodiment, the base 3 includes a top plate 32 and side plates 33 connected to opposite sides of the top plate 32; the second threaded hole 31 is opened on the top plate 32, and the bottom end of the jack 2 abuts against the top plate 32. The bottom ends of the two side plates 33 are supported on the ground, and the top plate 32 is connected between the top ends of the two side plates 33.

[0035] In this embodiment, the diameter of the second threaded hole 31 is 3 cm, the spacing between the two second threaded holes 31 is 27 cm, and the length of each screw rod 1 is 60 cm. It should be noted that in other embodiments, the size of the second threaded hole 31 and the size of the screw rod 1 can also be other values, and the size of the second threaded hole 31 and the screw rod 1 is not specifically limited.

[0036] Further, the rod diameter of each screw rod 1 is 2 cm, and the load capacity of the jack 2 is 25 tons. Here, the size of the screw rod 1 and the load capacity of the jack 2 are not specifically limited.

[0037] It is understandable that the weight of the jack 2 itself is also heavy. If the bottom end of the jack 2 is in direct contact with the base 3, the base 3 may be damaged. Therefore, as an optional embodiment, a buffer pad 4 is provided on the top of the top plate 32. In this way, certain damage to the base 3 can be avoided, thereby extending the service life of the base 3 and avoiding frequent replacement of the base 3.

[0038] As the driving wheel disassembly device provided in this embodiment is used, the buffer pad 4 may be worn. To facilitate the disassembly and replacement of the buffer pad 4, in this embodiment, the buffer pad 4 is detachably connected to the top plate 32, for example, by a snap-fit ​​connection.

[0039] Please combine Figure 4 and Figure 5 , Figure 4 This is a schematic diagram of the connection structure between the buffer pad and the base in the driving wheel disassembly device provided in an embodiment of the present application, Figure 5 for Figure 4 The enlarged schematic diagram of the local structure at A in the middle is shown. Specifically, the bottom of the buffer pad 4 is provided with a plurality of spaced protrusions 41, and the plurality of protrusions 41 are located between the two second threaded holes 31; the top plate 32 is provided with a plurality of holes 321, and one hole 321 corresponds to a protrusion 41, and the protrusion 41 is engaged with the corresponding hole 321 to detachably connect the buffer pad 4 and the top plate 32.

[0040] The clamping protrusion 41 includes a connecting column 411 and a clamping portion 412. The connecting column 411 is arranged at the bottom end of the buffer pad 4 and extends downward. The clamping portion 412 is connected to the bottom end of the connecting column 411, and the diameter of the clamping portion 412 gradually decreases in the downward direction. In addition, the diameter of the top end of the clamping portion 412 is larger than the inner diameter of the clamping hole 321. In this way, the clamping portion 412 can pass through the clamping hole 321 and then abut on the bottom end of the top plate 32. In this way, the clamping connection between the buffer pad 4 and the base 3 can be achieved.

[0041] In addition, the engagement connection between the plurality of latch protrusions 41 and the plurality of latch holes 321 can also enhance the reliable connection between the buffer pad 4 and the top plate 32, thereby preventing the buffer pad 4 from falling off when the driving wheel disassembly device provided in this embodiment is used.

[0042] It should be noted that, in this embodiment, the above-mentioned buffer pad 4 can be made of elastic material, such as rubber. Here, the material of the buffer pad 4 is not specifically limited.

[0043] The above contents are only specific implementation methods of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
