[0002] There is a kind of scooter that is driven by tracks to pass through some special sections of roads such as snow, mud or sand. The track assembly used in these scooters generally includes a track body and a drive component for driving the track body to transmit forward and backward, and also includes an inner and outer drive ring for driving the track body. The inner drive ring and the outer drive ring are fixedly connected by multiple bolts, wherein: the inner drive ring is sleeved on the outside of the drive component by interference fit and is driven to rotate by the drive component; the outer drive ring is engaged and connected to the inside of the track body, and can drive the track body to rotate together. When the drive component rotates the inner drive ring, the inner drive ring drives the outer drive ring and the track body to rotate around the axis of the drive component to achieve forward and backward transmission. The track assembly has the following disadvantages: on the one hand, the drive assembly drives the track body through the outer drive ring and the inner drive ring, and the inner drive ring is sleeved on the outside of the drive assembly in an interference fit manner and is driven by the drive assembly. It is easy to wear after long-term use, causing slippage between the inner drive ring and the drive assembly, affecting the transmission; on the other hand, in order to repair, maintain or clean the track assembly, it is necessary to remove the track body, outer drive ring, inner drive ring and drive assembly one by one before performing corresponding operations on the removed components, and after the operation is completed, they need to be assembled one by one, which is cumbersome and time-consuming.

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with specific implementation methods.

[0022] See Figure 1 The crawler drive assembly 1 includes a cylindrical shell side wall 21, a left end plate 22 and a right end plate 23 (see Figure 2 ) are detachably mounted on the left and right ends of the cylindrical shell side wall 21 by bolts (not shown in the figure), and together with the cylindrical shell side wall 21, they together form the outer shell 2 of the crawler drive assembly 1. Figure 2 The housing 2 contains a columnar mounting member 3, which is horizontally arranged on the left and right sides, and its left and right ends respectively penetrate the left and right end plates 23 of the housing 2 and extend out of the housing 2, and the mounting member 3 and the housing 2 can rotate relative to each other. The track drive assembly 1 is fixedly mounted on the body of the scooter (not shown in the figure) by means of the left and right ends of the mounting member 3 extending out of the housing 2, and its principle is the existing technology and will not be repeated here.

[0023] See inside the shell 2 Figure 4 The drive motor 4 is accommodated therein and fixedly mounted on the mounting member 3, and is supported by the housing 2 (see Figure 2 ) protection. The rotating shaft 41 of the driving motor 4 extends to the left along the mounting member 3, is sleeved on the outside of the mounting member 3, is coaxial with the mounting member 3, and can rotate relative to the mounting member 3. A driving gear 42 is sleeved on the left end of the rotating shaft 41. Figure 2 The inner wall surface of the cylindrical shell side wall 21 of the housing 2 is fixedly mounted with an annular toothed disc 24, and a mounting plate 61 (see Figure 3 ), the mounting plate 61 is fixedly mounted on the mounting member 3. The three gears 5 are shown in FIG. Figure 4 , each rotatably mounted on the mounting plate 61 (see Figure 3) on the right side, the driving gears 42 surrounding the driving motor 4 are arranged at intervals in the circumferential direction. The three gears 5 are located between the driving gear 42 and the toothed disc 24, providing meshing transmission for the driving gear 42 and the toothed disc 24. When the driving motor 4 is started, the rotating shaft 41 drives the driving gear 42 sleeved thereon to rotate around its own horizontal axis. The rotation of the driving gear 42 drives the three gears 5 to rotate, thereby driving the toothed disc 24 to rotate around the horizontal axis along with the driving gear 42. The cylindrical shell side wall 21 and the left and right end plates 23 mounted thereon also rotate relative to the mounting member 3 around the horizontal axis, that is, the driving motor 4 drives the connecting shell 2. See Figure 5 The mounting member 3 has a wire groove 31, the right end of which is located outside the housing 2 and the left end is located inside the housing 2. The electrical connection wire can extend from outside the housing 2 through the wire groove 31 into the housing 2 to control the connection with the drive motor 4 accommodated in the housing 2. In other embodiments, the left and right end plates 23 may not be mounted on the cylindrical housing side wall 21, but may be mounted on the mounting member 3 instead. Accordingly, the drive motor 4 is only connected to the cylindrical housing side wall 21.

[0024] The crawler drive assembly 1 and the crawler body (not shown in the figure) need to be assembled together to obtain a crawler assembly (not shown in the figure). Figure 1 and Figure 2 The cylindrical shell side wall 21 of the crawler drive assembly 1 is integrally formed with a driving part 211 extending outward. The driving part 211 is annular in shape as a whole, and its left and right sides are partially left empty to form a plurality of circumferentially spaced cavities 2111, and the cavities 2111 on the left and right sides are aligned one by one. The beginning and end of the crawler body (not shown in the figure) can be detachably docked and surrounded together, and the inner side of the surrounded crawler body is correspondingly provided with a plurality of spaced bosses (not shown in the figure). The crawler body is surrounded as above and wrapped around the outer side of the cylindrical shell side wall 21 of the crawler drive assembly 1, so that the plurality of bosses are respectively aligned and embedded in the plurality of cavities 2111, and the crawler drive assembly 1 and the crawler body are assembled together to obtain a crawler assembly (not shown in the figure). The cylindrical shell side wall 21 of the crawler drive assembly 1 is driven by the driven motor 4 to rotate forward and backward, and the driving part 211 drives the crawler body to drive forward and backward through the driving part 211. If it is necessary to disassemble the assembled crawler assembly for repair, maintenance or cleaning, it is only necessary to undocking the beginning and the end of the crawler body, so that the crawler body no longer wraps the outer side of the cylindrical shell side wall 21 of the crawler drive assembly 1, and the crawler drive assembly 1 is detached from the crawler body, and the crawler assembly is completely disassembled. Since the crawler drive assembly 1 of the utility model only uses the driving part 211 to dock with the boss of the crawler body, the crawler assembly can be assembled, and no other accessories are required to be arranged between the crawler drive assembly 1 and the crawler body. Therefore, when it is necessary to repair, maintain or clean the crawler assembly, it is only necessary to disassemble the assembled crawler drive assembly 1 and the crawler body, and the assembly and disassembly are relatively simple and time-saving.

[0025] The above is only an implementation method of the invention, and does not limit the scope of patent protection. Those skilled in the art can make non-substantial changes or substitutions based on the invention, which still fall within the scope of patent protection.
