[0024] A lower swing cylinder 13 is provided on the inner side of the dustproof rubber sleeve 8, a universal joint 14 is installed at the bottom end of the lower swing cylinder 13, an upper swing cylinder 15 is slidably provided on the top end of the lower swing cylinder 13, a spring 16 is sleeved on the outer side of the upper swing cylinder 15, a pressure valve 17 is installed inside the upper swing cylinder 15, an oil nozzle 18 is installed on the surface of the lower swing cylinder 13, an oil guide pipe 19 is installed on the pressure valve 17, and an oil outlet pipe 20 is installed between the pressure valve 17 and the oil nozzle 18. By connecting one end of the bushing 3 of the metal arm body 1 to the vehicle frame, by connecting one end of the rod of the ball head 7 to the vehicle steering knuckle, and by connecting the oil guide pipe 19 to the external oil cylinder, lubricating oil can be transported to the inside of the oil guide pipe 19 for subsequent lubrication between the rotating ball seat 6 and the ball head 7.

[0025] Furthermore, the oil guide pipe 19 passes through the upper swing cylinder 15 and the dustproof rubber sleeve 8 and is connected to the external oil cylinder. The outlet end of the oil nozzle 18 faces the side of the ball head 7. When the ball head 7 rotates and drives the dustproof rubber sleeve 8 to deform, the oil guide pipe 19 has a sufficient length to move with the dustproof rubber sleeve 8, thereby avoiding interference between the deformation process of the dustproof rubber sleeve 8 and the oil guide pipe 19.

[0026] Furthermore, one end of the spring 16 is fixedly connected to the lower swing cylinder 13, and the other end of the spring 16 is fixedly connected to the upper swing cylinder 15. The lower swing cylinder 13 and the upper swing cylinder 15 form a telescopic swing cylinder. The top end of the upper swing cylinder 15 is rotatably connected to the rod portion on the surface of the ball head 7 through the universal joint 14, and the bottom end of the lower swing cylinder 13 is rotatably connected to the rotating ball seat 6 through the universal joint 14. That is, the top end of the telescopic swing cylinder is rotatably connected to the rod portion on the surface of the ball head 7 through the universal joint 14, and the bottom end of the telescopic swing cylinder is rotatably connected to the rotating ball seat 6 through the universal joint 14. Therefore, during the rotation of the ball head 7, the telescopic swing cylinder can be driven to extend or contract through the universal joint 14, and the ball head 7 will not interfere with the telescopic swing cylinder.

[0027] Furthermore, the bottom oil shell 9 is fixedly connected to the rotating ball seat 6 by bolts, and the outer shell 10 is fixedly connected to the ball head sleeve 2 by bolts. The bottom oil shell 9 is umbrella-shaped, and the oil pipe at the top of the oil unloading valve 11 extends to the interior of the bottom oil shell 9. The lubricating oil sprayed on the surface of the ball head 7 can fall into the bottom oil shell 9. The oil can be collected through the umbrella-shaped bottom oil shell 9 and discharged through the oil unloading valve 11 and the oil unloading pipe 12 so that the oil can be recycled.

[0028] Furthermore, a ring-shaped T-groove is provided at the top of the rotating ball seat 6, and a ring-shaped T-ring is provided at the bottom end of the dust-proof rubber sleeve 8. The dust-proof rubber sleeve 8 is movably connected to the rotating ball seat 6 through the T-ring and the T-groove, and the top end of the dust-proof rubber sleeve 8 is sleeved on the rod of the ball head 7, so that the dust-proof rubber sleeve 8 can be quickly connected and fixed to the rotating ball seat 6 through the T-ring and the T-groove. Therefore, the dust-proof rubber sleeve 8 can be quickly installed on the rotating ball seat 6 and the rod of the ball head 7 to prevent dust from entering between the rotating ball seat 6 and the ball head 7.

[0029] Furthermore, the metal arm body 1 is in a trident shape, the ball head sleeve 2 is fixed at one end of the metal arm body 1, and the bushing 3 is fixed at the other two ends of the metal arm body 1. A connecting structure connected to the vehicle frame is provided inside the bushing 3. Therefore, one end of the bushing 3 of the metal arm body 1 can be connected to the vehicle frame through the connecting structure, and one end of the rod of the ball head 7 can be connected to the vehicle steering knuckle, so that the metal arm body 1 can play a role in supporting steering.

[0030] Furthermore, the reinforcing rib 5 is overall in a trident shape and has the same shape as the metal arm body 1. The reinforcing rib 5 is composed of two groups of X-shaped reinforcing ribs. The top and bottom ends of the reinforcing rib 5 are fixedly connected to the internal top and bottom surfaces of the metal arm cavity 4. One end of the reinforcing rib 5 is fixedly connected to the ball head sleeve 2, and the other two ends of the reinforcing rib 5 are fixedly connected to two groups of bushings 3, so that the strength of the metal arm body 1 can be strengthened by the reinforcing rib 5, and the stability of the ball head sleeve 2 and the bushing 3 when connected to the metal arm body 1 can be enhanced.

[0031] When in use, by connecting one end of the connecting structure inside the bushing 3 of the metal arm body 1 to the vehicle frame, by connecting one end of the rod of the ball head 7 to the vehicle steering knuckle, and by connecting the oil guide pipe 19 to the external oil cylinder, lubricating oil can be transported to the inside of the oil guide pipe 19. When the ball head 7 rotates, it can drive the upper swing cylinder 15 to slide inside the lower swing cylinder 13, and the upper swing cylinder 15 can drive the pressure valve 17 to move. Due to the pressure difference on both sides of the pressure valve 17, and when the system pressure exceeds the set value of the pressure valve 17, the valve will automatically open to release part of the lubricating oil to reduce the system pressure. When the system pressure drops to within the set range, the valve is closed, that is, when the upper swing cylinder 15 drives the pressure valve 17 to approach the lower swing cylinder 13, the telescopic swing cylinder composed of the lower swing cylinder 13 and the upper swing cylinder 15 contracts, and the pressure valve 17 opens, The lubricating oil in the external oil cylinder can be transported to the oil nozzle 18 through the oil guide pipe 19, the pressure valve 17 and the oil outlet pipe 20, and the oil nozzle 18 can spray the lubricating oil onto the surface of the ball head 7. When the upper swing cylinder 15 drives the pressure valve 17 away from the lower swing cylinder 13, the telescopic swing cylinder composed of the lower swing cylinder 13 and the upper swing cylinder 15 is extended, and the pressure valve 17 is closed. Therefore, during the rotation of the ball head 7, the lubricating oil can be sprayed intermittently onto the surface of the ball head 7, so that the surface of the ball head 7 can be continuously lubricated. In addition, a reinforcing rib 5 is welded and fixed to the inside of the metal arm body 1, and the upper and lower sides of the reinforcing rib 5 are fixedly connected to the upper and lower sides of the metal arm body 1, one end of the reinforcing rib 5 is fixedly connected to the ball head sleeve 2, and the other two ends are fixedly connected to the bushing 3, which can increase the strength of the metal arm body 1 during use and improve the supporting force of the ball head sleeve 2 and the bushing 3 during use.
