[0002] With the rapid development of the transportation industry, heavy-duty trucks, as the main force of logistics transportation, are receiving more and more attention for their performance and safety. The steering system is an important component of heavy-duty trucks, which directly affects the vehicle's handling stability, operating safety and tire service life. In the steering system of heavy-duty trucks, the steering tie rod is a key component connecting the wheels and the steering mechanism, and its performance is particularly important.

[0003] In the prior art, traditional lubrication systems often rely on regular visits to repair shops to replace lubricants to maintain a good lubrication state. However, since heavy-duty trucks often operate under harsh road conditions, long-term high-load operation will lead to the consumption of lubricants, and traditional maintenance methods are not timely or effective, resulting in the gradual weakening of the lubrication effect, affecting the lubrication effect. Therefore, in response to the above problems, we propose a new type of low-torque steering tie rod for heavy-duty trucks. Utility Model Content

[0004] The purpose of the utility model is to solve the problem in the prior art that heavy-loaded trucks often run under harsh road conditions, and long-term high-load operation will lead to consumption of lubricating grease, while traditional maintenance methods are not timely or effective enough, resulting in the gradual weakening of the lubrication effect, affecting the lubrication effect, and a low-torque steering tie rod for heavy-loaded trucks is proposed.

[0012] Preferably, the top of the connecting pipe is fixedly connected to a storage barrel, and the top of the storage barrel is matched with a barrel cover.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, this design significantly improves the lubrication effect of the steering tie rod, effectively avoiding the heavy-load trucks often running under harsh road conditions. Long-term high-load operation will lead to the consumption of lubricating grease.

[0024] The effect achieved by the entire embodiment 1 is that when in use, the spherical sleeve 4 is first sleeved on the ball head 11, with the bottom open design facing downward, lubricating oil is applied to the inner wall of the spherical sleeve 4 and the outer surface of the ball head 11, the sponge 33 is sleeved on the outside of the spherical sleeve 4, the first circular shell 2 is sleeved on the sponge 33 from the right side, the first fixing ring 21 faces the left side, the fastening bolt 22 is passed through the mounting hole of the first fixing ring 21, and it is not tightened temporarily, the second circular shell 3 is sleeved on the sponge 33 from the left side, so that the second fixing ring 31 corresponds to the fastening bolt 22, the nut 32 is installed at the left end of the fastening bolt 22, and tightened one by one to ensure that the first circular shell 2 and the second circular shell 3 are tightly connected, the connecting rod 1, the reinforcement block 12 and the cross-tie rod body 6 are installed to ensure a firm connection, and the lubricating oil is injected into the channel formed by the first circular shell 2, the second circular shell 3 and the spherical sleeve 4 through the connecting pipe 51, the lubricating oil will flow into the sponge 33 and be absorbed by it, so as to realize the storage of the lubricating oil, and the driver When the steering wheel is turned, the steering force is transmitted to the connecting rod 1 through the steering mechanism, pushing the ball head 11 to move. When the spherical sleeve 4 rotates, the sponge 33 is squeezed to squeeze out the adsorbed lubricating oil. The lubricating oil flows into the outer surface of the ball head 11 through the flow groove 41 on the spherical sleeve 4 to provide appropriate lubrication. As the steering operation proceeds, the lubricating oil is continuously squeezed out and distributed between the ball head 11 and the spherical sleeve 4 to achieve a continuous lubrication effect. This design significantly improves the lubrication effect of the steering tie rod 6, effectively avoiding the heavy-load trucks often running under harsh road conditions. Long-term high-load operation will lead to the consumption of lubricating grease.

[0025] Example 2: Figure 1-Figure 4 As shown, the top of the connecting pipe 51 is fixedly connected to the storage barrel 5 , and the top of the storage barrel 5 is matched with a barrel cover 52 .

[0026] The effect achieved by the entire embodiment 2 is that the storage barrel 5 can store a certain amount of lubricating oil, which is convenient for timely supply when the ball head 11 and the spherical sleeve 4 are out of lubricating oil, and the lubricating oil in the storage barrel 51 will continuously flow into the sponge 33 through the connecting pipe 5 and further flow into the ball head 11 and the spherical sleeve 4, providing continuous lubricating oil, thereby improving the lubrication effect, and the barrel cover 52 strengthens the sealing effect and facilitates the injection of new lubricating oil.

[0027] Working principle: When in use, first put the spherical sleeve 4 on the ball head 11, with the bottom open and facing downward, apply lubricating oil on the inner wall of the spherical sleeve 4 and the outer surface of the ball head 11, put the sponge 33 on the outside of the spherical sleeve 4, put the first circular shell 2 on the sponge 33 from the right side, with the first fixing ring 21 facing the left side, pass the fastening bolt 22 through the mounting hole of the first fixing ring 21, do not tighten it yet, put the second circular shell 3 on the sponge 33 from the left side, make the second fixing ring 31 correspond to the fastening bolt 22, install the nut 32 on the left end of the fastening bolt 22, and tighten them one by one. Ensure that the first circular shell 2 and the second circular shell 3 are tightly connected, install the connecting rod 1, the reinforcement block 12 and the tie rod body 6, ensure that the connection is stable, inject the lubricating oil into the channel formed by the first circular shell 2, the second circular shell 3 and the spherical sleeve 4 through the connecting pipe 51, and the lubricating oil will flow into the sponge 33 and be absorbed by it, so as to realize the storage of the lubricating oil. When the driver turns the steering wheel, the steering force is transmitted to the connecting rod 1 through the steering mechanism, pushing the ball head 11 to move, and the spherical sleeve 4 squeezes the sponge 33 when it rotates, squeezing the absorbed lubricating oil out, and the lubricating oil flows through the flow on the spherical sleeve 4. The groove 41 flows into the outer surface of the ball head 11 to provide an appropriate amount of lubrication. As the steering operation proceeds, the lubricating oil is continuously squeezed out and distributed between the ball head 11 and the spherical sleeve 4 to achieve a continuous lubrication effect. This design significantly improves the lubrication effect of the steering tie rod 6, effectively avoiding the heavy-duty trucks often running under harsh road conditions. Long-term high-load operation will lead to the consumption of lubricating grease. The adsorption and release mechanism of the lubricating oil by the sponge 33 ensures that the ball head 11 and the spherical sleeve 4 always get an appropriate amount of lubrication during the rotation process, reducing friction and wear and extending the service life of the components. At the same time, the design is easy to install and disassemble, easy to use for daily maintenance and lubricating oil replenishment, and improves the reliability and maintenance efficiency of the overall system. In addition, the storage barrel 5 can store a certain amount of lubricating oil, which is convenient for timely provision when the ball head 11 and the spherical sleeve 4 have no lubricating oil, and the lubricating oil in the storage barrel 51 will continuously flow into the sponge 33 through the connecting pipe 5 and further flow into the ball head 11 and the spherical sleeve 4, providing continuous lubricating oil, thereby improving the lubrication effect. The barrel cover 52 strengthens the sealing effect and facilitates the injection of new lubricating oil.
