[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 Figures 1-4 This utility model provides a technical solution: a ball joint pin seat for an automotive suspension arm, including a ball joint 1, a ball joint arm 2 disposed on the ball joint 1, and a ball shell 3. The ball shell 3 is composed of an upper ball shell 4 and a lower ball seat 5, and the upper ball shell 4 and the lower ball seat 5 are sealed and detachably connected. The ball joint 1 is located inside the ball shell 3. An I-shaped mounting plate 14 is fixedly provided on the outer surface of the ball joint arm 2. An I-shaped auxiliary mounting plate 6 is provided at the top height of the ball shell 3. A dust cover 7 is connected between the mounting plate 14 and the auxiliary mounting plate 6.

[0023] See Figures 1-4 The upper spherical shell 4 has a semi-circular spherical groove 8 inside, and the lower spherical seat 5 has a secondary semi-circular spherical groove 9 inside. Both the semi-circular spherical groove 8 and the secondary semi-circular spherical groove 9 are provided with wear-resistant rubber pads 10. A rectangular sealing groove 11 is formed on the top surface of the lower spherical seat 5. A rectangular insertion plate 12 is fixedly provided at the bottom end of the upper spherical shell 4. Sealing rings 13 are provided on both the inner and outer sides of the insertion plate 12. A rectangular sealing seat 15 with an open top is fixedly provided on the outer side of the lower spherical seat 5. A secondary sealing ring 16 is fitted onto the outer surface of the upper spherical shell 4. Corresponding mounting seats 17 are fixedly provided on the outer sides of the rectangular sealing seat 15 and the outer side of the upper spherical shell 4. The mounting seats 17 have threaded holes. An annular oil groove 18 and several oil storage tanks 19 are provided on the inner cavity of the wear-resistant rubber pad 10. The oil storage tanks 19 are distributed on both sides of the oil groove 18. The mounting plate 14 and the secondary sealing ring 11 are also provided. The mounting plate 6 is equipped with a clamping spring 20, which consists of two hinged semi-circular plates. Mounting pieces 21 are fixed on the semi-circular plates and are fixed together with bolts. The insertion plate 12 is inserted into the sealing groove 11, and the sealing ring 13 is located in the sealing groove 11 to ensure the sealing after docking. The rectangular sealing seat 15 wraps around the upper spherical shell 4, and the secondary sealing ring 16 on the outer surface of the upper spherical shell 4 is located in the rectangular sealing seat 15 to ensure resealing after installation. The grease will be squeezed, but due to the overall sealing structure, it will not be squeezed out. Instead, it will be squeezed into the oil storage tanks 6 on both sides of the oil groove 5 to increase the lubrication range. Alternatively, lubricating oil can be directly applied to the oil groove 18 and several oil storage tanks 19. The upper and lower ends of the dust cover are respectively formed into outward-turned flanges into the mounting plate 14 and the secondary mounting plate 6. The clamping spring is fastened in the mounting plate 14 and the secondary mounting plate 6, and the clamping spring is finally fixed with bolts.

[0024] In practical operation, the upper ball shell 4 and the lower ball seat 5 form the ball shell 3. The upper ball shell 4 and the lower ball seat 5 can be disassembled and replaced individually. During assembly, the upper and lower ball seats are assembled separately and then connected by bolts, making assembly convenient. Furthermore, during maintenance, the upper and lower ball seats can be disassembled without replacing the entire component, significantly saving materials. After installation, a sealed connection exists between the upper ball shell 4 and the lower ball seat 5, ensuring a tight seal and preventing internal lubricating oil from leaking out of the ball shell 3. This guarantees the sealing and safety of the ball head pin during use. The insertion plate 12 is inserted into the sealing groove 11, and the sealing ring 13 is located within the sealing groove 11. To ensure sealing after docking, the rectangular sealing seat 15 encloses the upper spherical shell 4, and the secondary sealing ring 16 on the outer surface of the upper spherical shell 4 is located inside the rectangular sealing seat 15, ensuring resealing after installation. The grease will be squeezed, but due to the overall sealing structure, it will not be squeezed out, but will be squeezed into the oil storage tanks 6 on both sides of the oil groove 5, increasing the lubrication range. Alternatively, lubricating oil can be directly applied to the oil groove 18 and several oil storage tanks 19. The upper and lower ends of the dust cover are respectively formed into outward-turned flanges into the mounting plate 14 and the secondary mounting plate 6. The clamp spring is fastened in the mounting plate 14 and the secondary mounting plate 6, and the clamp spring is finally fixed with bolts.
