Specific implementation mode

[0028] As Figures 1 to 2 shown, it is the first embodiment of the present utility model. The front - wheel steering suspension ball head includes a fixing plate 1 and a ball head seat 3. The ball head seat 3 is used for rotatably connecting a ball head pin. A through hole 2 is provided on the fixing plate 1, and a detachable ball head seat 3 is arranged in the through hole 2. The ball head seat 3 can be fixed in the through hole 2 by spot welding, which is convenient for cutting the ball head seat 3 out of the through hole 2 during disassembly. Adhering to the concept of environmental protection and green, the present utility model sets a separate ball head seat 3 on the fixing plate 1. The replacement of the ball head seat 3 will not affect the whole of the fixing plate 1, thus playing a role in saving part materials.

[0029] A number of connecting holes 4 are provided on the fixing plate 1. The connecting holes 4 are arranged on the side far from the through hole 2 and are distributed in a triangular shape, ensuring the stability of the connection. A thickened plate 5 is provided along the edge of the connecting hole 4 to increase the plate body strength of the connecting plate hole edge and avoid deformation. A retaining edge plate 9 is provided at the end of the ball head seat 3. An annular groove 26 is formed between the ball head seat 3, the retaining edge plate 9 and the fixing plate 1. The annular groove 26 is used for clamping a dust cover.

[0030] As Figures 3 to 8 shown, it is the second embodiment of the present utility model. On the basis of the first embodiment, the ball head seat 3 includes a first part 12 and a second part 6. One end of the second part 6 is provided with a retaining edge plate 9, and the other end is provided with a first part 12. The diameters of both the retaining edge plate 9 and the first part 12 are larger than the diameter of the through hole 2, so that the second part 6 is limited in the through hole 2.

[0031] An embedding groove 7 is provided at the end of the first part 12. The end of the second part 6 is fitted into the embedding groove 7. One side of the embedding groove 7 is inclined, so that a welding groove 8 is formed between one side of the embedding groove 7 and the second part 6, facilitating the welding of the first part 12 and the second part 6.

[0032] Inside the first branch 12, there is a ball bowl 24. The first branch 12 includes a first annular plate 10 and a second annular plate 11. The second annular plate 11 is fixed inside the first annular plate 10. The height of the first annular plate 10 is greater than that of the second annular plate 11. A limiting plate 13 is provided at the end of the first annular plate 10. The first annular plate 10 forms a limiting groove 25 for limiting the ball bowl 24 between the second annular plate 11 and the limiting plate 13. The first annular plate 10 is also provided with a cover body 15. The cover body 15 is provided with a groove 23. A raised block 14 is provided on the limiting plate 13. The groove 23 and the raised block 14 are matched and connected. The diameter of the end three 21 of the first annular plate 10 is greater than the diameter of the end four 22, and there is an arc transition in the middle, so that the first annular plate 10 can better limit the ball bowl 24 and the ball head pin.

[0033] The ball bowl 24 includes an outer ring 18 and a semi-circular support plate 16. The diameter of the end one 19 of the semi-circular support plate 16 is greater than the diameter of the end two 20, and there is an arc transition in the middle. The semi-circular support plate 16 is oppositely arranged inside the outer ring 18. The outer ring 18 is provided with a connecting rod 17. The end of the connecting rod 17 is fixed to the end one 19 on one side of the semi-circular support plate 16. The end two 20 on the other side of the semi-circular support plate 16 is a free end, so that the semi-circular support plate 16 elastically matches the shape of the ball head pin, and thus can better promote the rotation of the ball head pin.

[0034] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all covered by the protection scope of the present invention.
