[0018] Figure 3 It is a partial top view schematic diagram of an embodiment of the utility model. DETAILED DESCRIPTION

[0019] The utility model is further described below in conjunction with the accompanying drawings: As shown in the figure, a stabilizer rod connecting rod comprises a rod body 1 and a shell 2 connected to the rod body, a ball seat 3 is provided in the shell, and a ball pin 4 is also included, and part of the ball pin extends into the shell and is provided with a ball head 41 that matches the ball seat; it also comprises an oil injection channel 21, which is arranged on the shell and the ball seat and is used to inject oil into the ball head; an oil groove 411 is arranged on the circumferential outer wall of the ball head and extends along the radial direction of the ball head. An oil injection hole is newly added at the bottom. Compared with the traditional structure without an oil injection hole, adding lubricating oil can flush pollutants, reduce corrosion and wear of parts, and effectively improve the service life of the product. The ball adopts a slotted structure. Compared with the traditional structure without a slotted structure, this design ensures that the ball is better lubricated by oil injection, significantly reduces wear, and prolongs the service life of the ball pin. At the same time, the arc-shaped slotted structure can form an avoidance space, effectively preventing dust and other particles from entering to accelerate the wear of the ball and the ball seat, thereby prolonging the service life of the ball pin, and further improving the overall service life of the connecting rod.

[0020] In this embodiment, as shown in the figure, the ball seat is made of powder metallurgy. The ball seat is made of aluminum alloy powder metallurgy. Compared with traditional plastic materials, powder metallurgy can greatly improve the wear resistance of the product, effectively reduce the wear of the ball seat, and increase the life of the parts. It provides additional support for the performance and durability of the product.

[0021] In this embodiment, as shown in the figure, the housing includes a bottom plate 22 and a surrounding plate 23 integrally formed on the bottom plate. The housing adopts an integrated structure, eliminating the traditional sealing plate riveting assembly structure, avoiding the risk of the ball head coming out, improving the safety of the stabilizer bar connecting rod, and at the same time, the structure also saves the press-fitting process and reduces the production cost. The integrated structure enhances the strength of the ball shell and improves the stability of the stabilizer bar connecting rod.

[0022] In this embodiment, as shown in the figure, the bottom plate is provided with a detachable plug 221, which is used to block the oil injection channel after installation. In addition, a threaded connection is provided at the bottom of the shell and an oil nozzle is installed to facilitate the replacement of lubricating oil, making the product more convenient to use. The plug can be used for sealing only or can be realized by an oil nozzle (one-way valve).

[0023] In this embodiment, as shown in the figure, the bottom plate is provided with a threaded hole, and the plug is provided with a connector 222 which is threadably connected to the threaded hole.

[0024] In this embodiment, as shown in the figure, one end of the rod body is provided with a flange 11, and also includes a bolt 5 threadedly connected to the rod body, the bolt includes a cap, and a rubber pad 51 is installed between the cap and the flange. The use of flange-matched bolts eliminates nuts, reduces manufacturing costs, saves assembly time, simplifies the component replacement process, and improves installation convenience. At the same time, there is no need to use gaskets, simplifies the product assembly process, reduces manufacturing and labor costs, avoids the occurrence of abnormal noise caused by the contact between the gasket and the nut and the step surface, and improves the comfort of the car.

[0025] In this embodiment, as shown in the figure, the ball pin is provided with a boss 43 for operating with a square wrench. In addition, a square wrench position is adopted in the middle of the ball pin. The square wrench position is easier to install and disassemble, thereby improving the convenience of installation and disassembly, and thus reducing labor costs.
