[0036] Please refer to the attachedFigure 1 and appendage Figure 2 Around the top of the top shell 1, an anti-collision pad 20 is fixedly connected. Around the outer wall of the top shell 1, a sealing ring 22 is fixedly connected. At the top of the top shell 1, an upper inspection hole 23 is fixedly connected. At the top of the upper inspection hole 23, an upper sealing cover 24 is threadedly connected. The main function of the anti-collision pad 20 is to effectively protect the top shell 1 from damage caused by external impacts during the operation of the equipment.

[0038] Working principle: After the hydraulic torque converter has been used for a long time, the hydraulic oil inside will deteriorate and needs to be replaced. Rotate the rotating ring 19 to make the oil plug 17 rotate in the ring track 15 of the limiting ring 14, so that the oil plug 17 moves upward away from the inner wall of the oil change pipe 10. The combined action of the limiting body 11 and the sliding ring 12 prevents the oil plug 17 from detaching from the oil change pipe 10. Regularly changing the hydraulic oil can remove dirt and impurities, reduce wear, and extend the service life of the torque converter. Fresh hydraulic oil can maintain better fluidity and lubrication performance, improve the response speed and efficiency of the torque converter. Regular maintenance and replacement of the hydraulic oil can reduce the risk of failures and improve the overall reliability;

[0039] When the hydraulic torque converter is working, vibration and instability problems will occur under high-speed rotation. Through the connecting shell 201 and the fixed semi-ring 202 fixedly connected to the bottom of the bottom shell 9, they are threadedly fixed to the fixed ring 205 through the fixed bolt 206, and then the fixed semi-ring 202 and the fixed ring 205 are more closely and stably connected by the snap lock 203 and the lock catch 204. The fixing structure ensures more direct power transmission, reduces energy loss, improves transmission efficiency, has a relatively simple structure, is more convenient for maintenance and replacement, reduces maintenance costs, and the design of the fixing structure makes it perform stably under high loads, improving the overall durability.

[0040] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
