[0002] The steering tie rod is an important part in the automobile steering mechanism, which directly affects the stability of automobile control, the safety of operation and the service life of tires. The steering tie rod is divided into two types, namely, steering straight tie rod and steering cross tie rod. The steering straight tie rod bears the task of transmitting the movement of the steering rocker arm to the steering knuckle arm, and the steering cross tie rod is the bottom side of the steering trapezoidal mechanism, which is a key component to ensure the correct movement relationship of left and right steering wheels. However, the current steering tie rod has certain deficiencies. When installing or maintaining, the length of the tie rod needs to be adjusted to the appropriate size, and the tie rod needs to be removed from the steering rocker arm or the steering knuckle arm for adjustment, which is time-consuming and laborious, and has high working cost. Moreover, the long time will cause the ball head to wear out and the joint part to loosen, which has high safety risk. The dust cover is troublesome to disassemble, and the dust cover accumulates too much dust during long-term use, which reduces the efficiency and accuracy of the ball head during steering, and reduces the stability and safety of the automobile during driving.

[0010] Preferably, a disassembly groove is provided on one side of the top of the ball seat, the disassembly groove corresponds to the disassembly block, and the dust cover corresponds to the mounting sleeve. The use of the disassembly groove and the disassembly block makes it convenient to install the dust cover on the ball seat for dust prevention.

[0011] A method for preventing loosening of steering tie rods, the method comprising the following:

[0012] Step 1: By rotating the adjusting sleeve, under the action of the first left thread, the second left thread, the first right thread, and the second right thread, the left rod and the right rod move in opposite directions. The limiting plate moves within the limiting groove, which extends or shortens the pull rod. Adjusting the length of the pull rod to a suitable size facilitates installation or maintenance, reduces operating costs, and improves work efficiency.

[0013] Step 2: The ball head is driven by the ball pin to move, the ball head presses against the bearing sleeve, the bearing sleeve presses against the return spring, and the return spring presses against the opening and closing cover. The return spring buffers the force to prevent the ball head from repeatedly hitting the cover and causing damage to the device. At the same time, the rubber pad keeps the ball head pressed between the bearing sleeve and the insert sleeve to prevent the ball head from loosening and reduce safety hazards. When the ball head wears down after prolonged use, the return spring presses against the bearing sleeve to make the bearing sleeve fit against the ball head, preventing the formation of an excessive cavity in the middle and loosening, thus improving the quality of work.

[0014] Step 3: After a period of use, disconnect the sealing tube from the sealing tube through the first sealing thread and the second sealing thread. Add lubricating oil through the sealing tube. The lubricating oil enters the bearing sleeve through the oil inlet hole, contacts the ball head, and is guided by the lubrication groove on the ball head. This provides sufficient lubrication and maintenance for the ball head, improves its service life, prevents excessive wear and loosening, improves work quality, and reduces costs.

[0015] Step 4: After prolonged use, the ball head needs to be inspected and maintained. However, since the ball head is embedded in the ball seat, it cannot be removed. At this time, the opening and closing cover at the bottom of the ball seat can be removed through the first and second opening and closing threads. The opening and closing cover drives the return spring and the bearing sleeve away from the ball seat, allowing direct contact with the ball head for inspection and maintenance. This prevents damage and loosening, reduces safety hazards, and eliminates the need to replace the entire structure before the ball head is damaged, thus improving the service life of the ball head and reducing costs.

[0016] Step 5: After prolonged use, the dust cover will accumulate a lot of dust, reducing the efficiency and accuracy of the ball joint when turning. At this time, by pressing the push post, the push post will drive the moving plate to move. The moving plate will squeeze the disassembly spring, and the moving plate will drive the disassembly block from the disassembly slot into the moving slot to disassemble and clean the dust cover, improving work safety.

[0017] The beneficial effects of this invention are as follows: By rotating the adjusting sleeve, the left and right rods move in opposite directions under the action of the first left thread, the second left thread, the first right thread, and the second right thread, thus extending or shortening the pull rod and adjusting its length to a suitable size for convenient installation or maintenance. The ball head compresses the bearing sleeve, which in turn compresses the return spring, which in turn compresses the opening and closing cover. The return spring buffers the force, preventing repeated contact of the ball head and thus avoiding damage to the device. Under the action of the rubber pad and the return spring, when the ball head wears less, the return spring compresses the bearing sleeve, causing the bearing sleeve to contact the ball head. The design avoids excessive cavities between the ball head and the bearing sleeve, preventing loosening and improving work quality. The relative positions of the sealing tube and the bearing sleeve are controlled by the first and second sealing threads. The ball head is fully lubricated and maintained through the oil inlet and lubrication groove, extending its service life. The relative positions of the sealing cover and the ball seat are controlled by the first and second opening and closing threads, facilitating observation, inspection, and maintenance of the ball head. By pressing and holding, the moving plate moves, compressing the disassembly spring. The moving plate then moves the disassembly block away from the disassembly groove, allowing the dust cover to be removed and cleaned. This design is simple, convenient, and reduces operating costs.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-9As shown, this embodiment provides an anti-loosening steering tie rod assembly, including an adjusting sleeve 1, a left rod 2, a right rod 3, a ball seat 4, a ball head 5, a ball head pin 6, a dust cover 7, an anti-loosening component 8, a lubrication and maintenance component 9, and a disassembly and assembly component 10. The anti-loosening component 8 is disposed inside the ball seat 4 and includes a load-bearing sleeve 81, an insert sleeve 82, a return spring 83, a rubber pad 84, and an opening and closing cover 85. The opening and closing cover 85 is disposed at the bottom of the ball seat 4. The two ends of the return spring 83 are respectively fused to the bottom of the load-bearing sleeve 81 and the top of the opening and closing cover 85. The insert sleeve 82 is disposed at the top of the load-bearing sleeve 81 and on the inner wall of the ball seat 4. The rubber pad 84 is disposed on one side of the insert sleeve 82. The left rod 2 and the right rod 3... The ball seat 4 is located inside the adjusting sleeve 1, at one end of the left rod 2 and one end of the right rod 3. The ball head 5 is located inside the ball seat 4, and the ball head pin 6 is located on top of the ball head 5. The dust cover 7 is located on top of the ball seat 4, corresponding to the ball head 5. The lubrication and maintenance component 9 is located on one side of the ball seat 4 and on the ball head 5. The disassembly and assembly component 10 is located on the dust cover 7. The bottom of the ball seat 4 has an opening and closing hole with a first opening and closing thread 11. The opening and closing cover 85 has a second opening and closing thread 12. The first opening and closing thread 11 and the second opening and closing thread 12 correspond to each other. The relative position of the opening and closing cover 85 and the ball seat 4 is controlled by the first opening and closing thread 11 and the second opening and closing thread 12, which facilitates direct control. The ball is inspected and maintained to improve its service life and reduce costs. The ball head 5 is located on the bearing sleeve 81 and one side of the insert sleeve 82. A rubber pad 84 is placed between the ball head 5 and the insert sleeve 82. Under the action of the rubber pad 84 and the return spring 83, the ball head 5 is pressed between the bearing sleeve 81 and the insert sleeve 82 to prevent loosening and reduce safety hazards. An oil inlet hole 13 is provided on one side of the bearing sleeve 81, the insert sleeve 82, and the ball seat 4. The lubrication maintenance component 9 includes a lubrication groove 91 and a sealing structure 92. The lubrication groove 91 is located on the ball head 5, and the sealing structure 92 is located on one side of the ball seat 4. The sealing structure 92 is divided into a sealing tube 921 and a sealing... The sealing cap 922 and the sealing tube 921 are located on one side of the ball seat 4 and communicate with the oil inlet hole 13. The sealing cap 922 is set on the sealing tube 921. The sealing tube 921 has a first sealing thread 14. The sealing cap 922 has a sealing hole. The sealing hole has a second sealing thread 15. The second sealing thread 15 corresponds to the first sealing thread 14. The cooperation of the first sealing thread 14, the second sealing thread 15, the sealing cap 922 and the sealing tube 921 facilitates the control of the relative position of the sealing cap 922 and the sealing tube 921. The oil inlet pipe and the lubrication groove 91 facilitate the addition of lubricating oil to fully lubricate and maintain the ball head 5 and improve the service life of the ball head 5.

[0030] When installing and maintaining the steering tie rod, the length of the tie rod needs to be adjusted. By rotating the adjusting sleeve 1, the adjusting sleeve 1 drives the left rod 2 and right rod 3 to move in opposite directions within the adjusting sleeve 1 through the first left thread 16 and the first right thread 18, thus extending or shortening the steering tie rod. This facilitates installation and maintenance, improving work efficiency. During operation, the ball head pin 6 presses against the ball head 5, the ball head 5 presses against the bearing sleeve 81, and the bearing sleeve 81 presses against the return spring 83. Under the action of the return spring 83, the pressing force is buffered, reducing the impact wear of the ball head 5 and improving its service life. After the ball head 5 wears down, it will become smaller. Under the action of the return spring 83 and the rubber pad 84, excessive cavity is avoided between the ball head 5 and the bearing sleeve 81, preventing loosening and improving safety. After the ball head 5 has been used for a period of time, it needs to be lubricated and maintained to improve its service life. At this time, by rotating the sealing cover 922, the first sealing thread 14 and the second sealing thread 15 are connected. Under the action of the sealing cover 922, the sealing tube 921 is disengaged. Lubricating oil is added through the sealing tube 921 and the oil inlet 13. The lubricating oil enters the bearing sleeve 81 and contacts the ball head 5. Under the action of the lubrication groove 91, the ball head 5 is fully lubricated. After the ball head 5 has been used for a period of time, it needs to be inspected to check its wear and whether it needs to be replaced or maintained to avoid accidents during operation. By rotating the opening and closing cover 85, under the action of the first opening and closing thread 11 and the second opening and closing thread 12, the sealing cover 922 drives the return spring 83 and the bearing sleeve 81 to leave the ball seat 4, so that the ball head 5 can be inspected and maintained, reducing costs and improving safety. After the dust cover 7 has been used for a period of time, it needs to be cleaned. By pressing and holding, the moving plate 102 is moved. The moving plate 102 squeezes the disassembly and assembly spring 103, and the moving plate 102 drives the disassembly and assembly block 104 to leave the disassembly and assembly groove. The dust cover 7 can be removed and cleaned, which is simple and convenient and reduces working costs.

[0031] The adjusting sleeve 1 has a first left thread 16, a limiting groove 17, and a first right thread 18. The left rod 2 has a second left thread 19, and the right rod 3 has a second right thread 20. The first left thread 16 corresponds to the second left thread 19, and the first right thread 18 corresponds to the second right thread 20. The directions of the first left thread 16 and the first right thread 18 are opposite. Limiting plates 21 are provided at one end of the left rod 2 and one end of the right rod 3, and are located within the limiting groove 17. The coordinated use of the first left thread 16, the first right thread 18, the second left thread 19, the second right thread 20, the limiting groove 17, and the limiting plate 21 facilitates the extension or retraction of the pull rod, adjusting its length to a suitable size for installation or maintenance, reducing operating costs and improving work efficiency. The dust cover 7 has a moving groove, which is aligned with the outer wall of the dust cover 7. The spherical base 7 is provided with a first through hole and a second through hole. The disassembly and assembly component 10 is set in the moving groove. The disassembly and assembly component 10 includes a push post 101, a moving plate 102, a disassembly and assembly spring 103, and a disassembly and assembly block 104. The push post 101 is set on one side of the dust cover 7 and is locked in the first through hole. The moving plate 102 is fixedly welded to one side of the push post 101 and is set in the moving groove. The two ends of the disassembly and assembly spring 103 are respectively fused to one side of the moving plate 102 and the inner side wall of the moving groove. The disassembly and assembly block 104 is fixedly welded to one side of the bottom of the moving plate 102 and is locked in the second through hole. The ball seat 4 has a disassembly and assembly groove on one side of the top. The disassembly and assembly groove corresponds to the disassembly and assembly block 104. The dust cover 7 corresponds to the mounting sleeve 82. The use of the push post 101, the moving plate 102, the disassembly and assembly spring 103, and the disassembly and assembly block 104 facilitates the disassembly and assembly of the dust cover 7 and improves work safety.

[0032] By rotating the adjusting sleeve 1, under the action of the first left thread 16, the second left thread 19, the first right thread 18, and the second right thread 20, the left rod 2 and the right rod 3 move in opposite directions. The limiting plate 21 moves within the limiting groove 17, extending or shortening the pull rod to adjust its length to a suitable size, facilitating installation or maintenance, reducing operating costs, and improving work efficiency. During operation, the ball head 5 moves via the ball head pin 6, which presses against the bearing sleeve 81, which in turn presses against the return spring 83. The position spring 83 presses against the opening and closing cover 85, and the return spring 83 buffers the force to prevent the ball head 5 from being damaged by repeated contact. At the same time, the rubber pad 84 presses the ball head 5 between the bearing sleeve 81 and the insert sleeve 82 to prevent the ball head 5 from loosening and reduce safety hazards. When the ball head 5 wears down after prolonged use, the return spring 83 presses against the bearing sleeve 81 to make the bearing sleeve 81 fit against the ball head 5, preventing the formation of an excessive cavity in the middle and loosening, thus improving the working quality.

[0033] After a period of use, the ball head 5 needs to be lubricated and maintained. The sealing tube 921 is disconnected from the ball head 921 via the first sealing thread 14 and the second sealing thread 15. Lubricating oil is added through the sealing tube 921, entering the bearing sleeve 81 through the oil inlet 13 and contacting the ball head 5. Guided by the lubrication groove 91 on the ball head 5, the ball head 5 is fully lubricated and maintained, improving its service life, preventing excessive wear and loosening, improving work quality, and reducing costs. After prolonged use, the ball head 5 needs inspection and maintenance. However, because the ball head 5 is embedded in the ball seat 4, it cannot be removed. At this time, the opening and closing cover 85 at the bottom of the ball seat 4 is removed via the first opening and closing thread 11 and the second opening and closing thread 12. The opening and closing cover 85 drives the return spring 83 and the bearing sleeve 81 away from the ball seat 4, allowing direct contact with the ball head 5 for inspection and maintenance, preventing damage and loosening, reducing safety hazards, and eliminating the need to replace the entire structure before the ball head 5 is damaged, thus improving its service life and reducing costs.

[0034] After prolonged use, the dust cover 7 will accumulate a lot of dust, reducing the efficiency and accuracy of the ball head 5 when turning. At this time, by pressing the push post 101, the push post 101 drives the moving plate 102 to move. The moving plate 102 squeezes the disassembly spring 103, and the moving plate 102 drives the disassembly block 104 from the disassembly slot into the moving slot to disassemble and clean the dust cover 7, thereby improving work safety.

When the usage time is too long, the ball head (5) will wear. At this time, the return spring (83) squeezes the bearing sleeve (81) to make the bearing sleeve (81) fit with the ball head (5) to prevent the middle cavity from being too large and loosening. Step 3: After a period of use, the sealing tube (921) is removed from the sealing tube (921) through the first sealing thread (14) and the second sealing thread (15). Lubricating oil is added through the sealing tube (921). The lubricating oil enters the bearing sleeve (81) through the oil inlet hole (13) and contacts the ball head (5). It is guided by the lubrication groove (91) on the ball head (5) to fully lubricate and maintain the ball head (5) and prevent it from being worn too much and becoming loose. Step 4: After long-term use, the ball head (5) needs to be inspected and maintained. However, since the ball head (5) is embedded in the ball seat (4), it cannot be removed. At this time, the opening and closing cover (85) at the bottom of the ball seat (4) can be removed by the first opening and closing thread (11) and the second opening and closing thread (12). The opening and closing cover (85) drives the return spring (83) and the bearing sleeve (81) to leave the ball seat (4) and can directly contact the ball head (5) for inspection and maintenance, so as to avoid damage and loosening. It is not necessary to wait for the ball head (5) to be damaged and directly replace the entire structure, thus reducing costs. Step 5: After the dust cover (7) has been used for a long time, a lot of dust will accumulate, which will reduce the efficiency and accuracy of the ball head (5) when turning. At this time, by pressing the push post (101), the push post (101) will drive the moving plate (102) to move. The moving plate (102) will squeeze the disassembly spring (103). The moving plate (102) will drive the disassembly block (104) from the disassembly slot into the moving slot to disassemble and clean the dust cover (7).
