[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A one-piece forged thrust rod assembly includes a crossbar 1 and a connecting seat 2. Grooves 11 are formed at both ends of the crossbar 1. A reinforcing rib 12 is fixedly connected to the connection between the crossbar 1 and the connecting seat 2. A slot 21 is formed on the surface of the connecting seat 2, and a sealing plug 22 is inserted into the slot 21. A connecting hole 23 is formed inside the slot 21. An annular groove 24 is formed on the top of the inner wall of the connecting seat 2, and a retaining spring 25 is installed inside the annular groove 24. A bearing sleeve 3 is rotatably connected inside the connecting seat 2. An annular groove 31 is formed on the surface of the bearing sleeve 3, and multiple oil inlets 32 are formed on the surface of the annular groove 31. A lower rubber core stop 33 is rotatably connected to the bottom of the bearing sleeve 3, and an upper rubber core stop 34 is fixedly connected to the top of the bearing sleeve 3. A ball joint body 4 is rotatably connected inside the bearing sleeve 3. The crossbar 1, grooves 11, reinforcing ribs 12, and connecting seat 2 are provided. The crossbar 1 and connecting seat 2 are formed by one-piece forging. Compared with welding or bolted connections, the seamless design avoids stress concentration. To mitigate the risk of weld failure and better withstand high-frequency alternating loads, the H-shaped crossbar 1 exhibits significantly higher bending and torsional resistance than solid round or rectangular bars of the same weight. The hollow design with grooves 11 at both ends of the crossbar 1 naturally reduces material usage and lightens its weight. The connecting seat 2 is the area of ​​highest stress in the thrust rod, and the reinforcing ribs 12 form a triangular support structure to suppress deformation of the mounting surface of the connecting seat 2, ensuring accurate force transmission and reducing the risk of abnormal noise. It is equipped with a slot 21, a connecting hole 23, an annular groove 31, and an oil inlet 32. After removing the sealing plug 22, lubricating oil can be added to the slot 21. The lubricating oil enters the annular groove 31 on the surface of the bearing sleeve 3 through the connecting hole 23, and enters the space between the ball joint body 4 and the bearing sleeve 3 through the oil inlet 32 ​​equidistantly opened on the surface of the annular groove 31. This allows for the addition of lubricating oil between the connecting seat 2 and the bearing sleeve 3, and between the bearing sleeve 3 and the ball joint body 4, enabling all-round lubrication and further improving the service life of the crossbar 1.

[0024] Furthermore, the connecting seat 2 is fixedly connected to both sides of the crossbar 1. The connecting seat 2 and the crossbar 1 are integrally forged. Compared with welding or bolt connection, the seamless design avoids stress concentration and weld failure risk, and is more suitable for bearing high-frequency alternating loads.

[0025] Furthermore, the cross section of the crossbar 1 is H-shaped, and the surface of the crossbar 1 is provided with rounded corners, which significantly improves its bending and torsional resistance compared to solid round or rectangular bars.

[0026] Furthermore, the sealing plug 22 is made of rubber and can be replaced by an oil cup, etc., to facilitate the addition of lubricating oil. These are all existing technologies and will not be described in detail below.

[0027] Furthermore, the connecting hole 23 is connected to the annular groove 31, and multiple oil inlets 32 are equidistantly circumferentially opened on the surface of the annular groove 31. After removing the sealing plug 22, lubricating oil can be added to the slot 21. The lubricating oil enters the annular groove 31 on the surface of the bearing sleeve 3 through the connecting hole 23, and enters the space between the ball joint body 4 and the bearing sleeve 3 through the oil inlets 32 equidistantly opened on the surface of the annular groove 31. Thus, lubricating oil can be added between the connecting seat 2 and the bearing sleeve 3, and between the bearing sleeve 3 and the ball joint body 4.

[0028] Furthermore, the lower rubber core stop 33 is fixedly connected to the bottom of the inner wall of the connecting seat 2. The lower rubber core stop 33 can limit the bearing sleeve 3 from the bottom to prevent the bearing sleeve 3 from falling out of the connecting seat 2.

[0029] Furthermore, the retaining ring 25 is engaged in the annular groove 24, and the bottom of the retaining ring 25 contacts the top of the upper rubber core stop 34. Through the cooperation between the retaining ring 25 and the annular groove 24, the upper rubber core stop 34 on the bearing sleeve 3 is limited from the top, and the bearing sleeve 3 is restricted between the lower rubber core stop 33 and the retaining ring 25.

[0030] Working principle: The crossbar 1 and the connecting seat 2 are made by one-piece forging. Compared with welding or bolting, the seamless design avoids stress concentration and weld failure risks, making it more suitable for bearing high-frequency alternating loads. The H-shaped crossbar 1 has significantly higher bending and torsional resistance than a solid round or rectangular bar under the same weight. The hollow design with grooves 11 at both ends of the crossbar 1 naturally reduces material usage and lightens its weight. The connecting seat 2 is the area of ​​highest stress in the thrust rod. The reinforcing ribs 12 form a triangular support structure to suppress the stress on the connecting seat 2. The deformation of the mounting surface ensures accurate force transmission path and reduces the risk of abnormal noise. After removing the sealing plug 22, lubricating oil can be added to the slot 21. The lubricating oil enters the annular groove 31 on the surface of the bearing sleeve 3 through the connecting hole 23, and enters the space between the ball joint body 4 and the bearing sleeve 3 through the oil inlet 32 ​​equidistantly opened on the surface of the annular groove 31. This allows for the addition of lubricating oil between the connecting seat 2 and the bearing sleeve 3, and between the bearing sleeve 3 and the ball joint body 4. Lubricating oil can be poured in from all directions, further improving the service life of the crossbar 1.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
