[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In other words, the second traction weld 102 constitutes a connecting piece between the intermediate cylinder 100 and the frame of the operating machine. In some embodiments, one axial end of the intermediate cylinder 100 extends radially outward to form a flange structure 100a, and the other axial end is formed with a groove structure. Correspondingly, the traction mechanism also includes a flange body 101, which is assembled on the groove structure of the intermediate cylinder 100. The flange body 101 and the flange structure 100a at the other axial end of the intermediate cylinder 100 cooperate to achieve the connection between the intermediate cylinder 100 and the second traction weld 102. For details, refer to Figure 2 The second traction weld 102 has a coupling portion 102a sleeved on both ends of the intermediate cylinder 100 in the axial direction. The coupling portion 102a is connected to the flange structure 100a and the flange body 101 at both ends of the intermediate cylinder 100 in the axial direction by fasteners such as bolts to achieve a fixed connection between the intermediate cylinder 100 and the second traction weld 102. Figure 2 The traction arm body 200 is connected to the frame of the traction machine (such as a tractor, not shown) through the first traction weld 201, and the traction arm body 200 is connected to the intermediate cylinder 100 and is configured to rotate around the axis of the intermediate cylinder 100. At this time, the traction machine and the working machine are connected through the first traction weld 201, the traction arm body 200, the intermediate cylinder 100 and the second traction weld 102.

[0032] In some embodiments, reference Figure 1 The traction arm 200 has a first end 200a connected to the connecting cylinder 306 and a second end 200b connected to the traction machine. Figure 2 , wherein the first end 200a of the traction arm body 200 is roughly constructed as a cylindrical component that is covered on the radially outer side of the intermediate cylinder 100 to achieve a rotational connection between the first end 200a of the traction arm body 200 and the intermediate cylinder 100, that is, the traction arm body 200 can rotate around the axis of the intermediate cylinder 100. In some embodiments, a wear-resistant copper sleeve 204 is provided between the contact surfaces of the intermediate cylinder 100 and the first end 200a of the traction arm body 200 (i.e., between the outer wall of the intermediate cylinder 100 and the inner wall of the first end 200a of the traction arm body 200). Based on the wear-resistant copper sleeve 204, direct contact between the first end 200a of the traction arm body 200 and the intermediate cylinder 100 can be avoided to extend the overall life of the mechanism.

[0033] Reference Figure 1 and Figure 3 The second end 200b of the traction arm body 200 is connected to the frame of the traction machine through the first traction weld 201, that is, the first traction weld 201 is configured as a connecting piece between the traction machine frame and the traction arm body 200, and the first traction weld 201 and the traction arm body 200 are configured to be able to rotate synchronously around the axis of the intermediate cylinder 100 to maintain the connection between the traction machine and the working machine during the turning process of the traction machine. Further, the first traction weld 201 is configured to be able to rotate relative to the traction arm body 200, and its rotation axis is perpendicular to the traction machine frame. The first traction weld 201 is arranged on the axis of the intermediate cylinder 100. For example, the axis of the intermediate cylinder 100 is configured as a vertical axis. Correspondingly, the rotation axis of the first traction weld 201 is a horizontal axis. Based on the rotation of the first traction weld 201, when the traction machine travels on an uneven ground, the first traction weld 201 can swing left and right with the traction machine independently of the traction arm 200 (based on the traveling direction of the traction machine) to ensure the stability of the traction structure during the movement of the traction machine and the working machine. In some embodiments, refer to Figure 3 The first traction weld 201 is connected to the second end 200b of the traction arm body 200 through a pin shaft 203. Specifically, the second end 200b of the traction arm body 200 is installed with a pressure plate component 202 through fasteners such as screws. One end of the pin shaft 203 is fixed on the pressure plate component 202, and the other end extends toward the first end 200a of the traction arm body 200 and passes through the first traction weld 201. The connection is based on the pin shaft 203 to realize the rotation of the first traction weld 201 relative to the traction arm body 200.

Exemplarily, the input shaft and the output shaft are assembled on the housing through bearings, etc. In order to distinguish them, the first and second pairs of components of the transmission case 300 and the transfer case 400 are named to achieve distinction.

Further, the following portion 303 is mounted on the locking portion 302 and is configured to rotate around the axis of the intermediate cylinder 100. Based on the rotation of the following portion 303 and in conjunction with the subsequent connection between the first output shaft 305 and the second input shaft 402, the connection between the traction machinery and the working machinery during the steering process of the traction machinery can be achieved. The following portion 303 and the locking portion 302 constitute a rotational connection. For example, referring to Figure 4 The following part 303 has a second extension part 303a, and the locking part 302 has a first extension part 302a. Both the first extension part 302a and the second extension part 303a are constructed as tubular parts extending along the extension line of the axis of the intermediate cylinder 100. At the same time, the second extension part 303a is arranged on the radial inner side of the first extension part 302a, and a gap interval is formed between the first extension part 302a and the second extension part 303a, and a bearing is correspondingly arranged in the gap interval to realize the rotational connection between the first locking part 302 and the following part 303.

In some embodiments, the follower 303 of the first shell 301 is connected to the traction arm body 200 through a fixed plate 307. For example, the second end 200b of the traction arm body 200 extends outward along the radial direction of the intermediate cylinder 100, and the structure between the first end 200a and the second end 200b of the traction arm body 200 is roughly constructed as a plate-shaped component.

Back to Figure 2, continue to explain the traction structure, one end of the first input shaft 304 of the transmission case 300 is connected to the power output end of the traction machine, and correspondingly, one end of the second output shaft 403 of the transfer case 400 is connected to the power input end of the working machine, and one end of the first output shaft 305 of the transmission case 300 and one end of the second input shaft 402 of the transfer case 400 are extended along the axis of the intermediate cylinder 100 into the intermediate cylinder 100, and are connected by a coupling 500 to realize the dynamic coupling of the output shaft of the transmission case 300 and the input shaft of the transfer case 400. Force transmission, and the first housing 301 and the second housing 401 are both configured with a transmission structure 501, wherein the transmission structure 501 in the first housing 301 is configured in the follower 303, for realizing power transmission between the first input shaft 304 and the first output shaft 305, the second input shaft 402 and the second output shaft 403. In some embodiments, the transmission structures 501 in the first housing 301 and the second housing 401 are both configured as bevel gear transmission structures 501. Exemplarily, the arrangement of the transmission structure 501 in the first housing 301 is taken as an example for description, and reference is made to FIG. Figure 4 The first input shaft 304 and the first output shaft 305 are provided with bevel gears (such as bevel gears) meshing with each other, and the power transmission between the first input shaft 304 and the first output shaft 305 is realized based on the bevel gears. At this time, the power output of the traction machinery is transmitted to the working machinery via the first input shaft 304, the transmission structure 501 in the first housing 301 (follower part 303), the first output shaft 305, the coupling 500, the second input shaft 402, the transmission structure 501 in the second housing 401 and the second output shaft 403, so as to realize the power transmission between the traction machinery and the power machinery, and during the steering process of the traction machinery, the follower part 303 rotates with the traction arm body 200 when turning, so as to realize the turning operation without stopping the machine, and effectively protect the first output shaft 305 of the transmission case 300 and the second input shaft 402 of the transfer case 400 from being subjected to axial and radial forces when turning, thereby improving the service life of the transmission gearbox body and the transfer case 400.
