[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1

[0023] like Figures 1-4 As shown, to achieve the above objectives, this utility model provides the following technical solution: A ball joint for an automotive swing arm, comprising a base 1 and a movable ball 9. A cover 7 is installed on the top of the base 1 via a locking screw 2. A movable ball 9 is installed at the gap between the base 1 and the cover 7 via a movable groove 8. A connecting post 4 is installed on the top of the movable ball 9. An oil reservoir 11 is screwed onto the bottom of the base 1 via a connecting groove 10. An oil reservoir 17 is provided at the top of the oil reservoir 11. A compression seat 16 is installed at the bottom of the oil reservoir 17. A sponge 18 is installed inside the oil reservoir 17 at the top of the compression seat 16. The sponge 18 is filled with... The base 1 is filled with lubricating oil. An oil hole 19 is provided at the top of the connecting groove 10 inside the base 1. The end of the oil hole 19 is connected to the inside of the movable groove 8. The lubricating oil is guided into the movable groove 8 through the oil hole 19. A disassembly boss 12 is installed at the bottom of the oil reservoir 11. A spring seat 13 is installed at the bottom of the disassembly boss 12. The extrusion seat 16 is inserted into the inside of the spring seat 13. A spring groove 15 is provided at the bottom of the extrusion seat 16 inside the spring seat 13. A spring 14 is installed inside the spring groove 15. The extrusion seat 16 is extruded by the spring 14, thereby extruding the lubricating oil inside the sponge 18.

[0024] The working principle of the ball joint for an automotive swing arm based on Embodiment 1 is as follows: After the present invention is installed, it is connected to the automotive suspension mechanism through the connecting column 4.
