[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] like Figures 1-8 The illustration shows a front wheel hub for a vehicle, including a hub 1. The hub 1 has a mounting plate 3. A central hole 4 is provided at the center of the mounting plate 3. Both ends of the central hole 4 are provided with a first protruding ring 22 and a second protruding ring 23 extending outward. The first protruding ring 22 and the second protruding ring 23 are joined together to form a mounting post. A front wheel hub insert 6 is installed in the mounting post. The front wheel hub insert 6 is tightly fitted with the mounting post. Bearings 9 are installed at both ends of the front wheel hub insert 6. A front wheel axle 8 passes through the front wheel hub insert 6. The bearings 9 are sleeved on the front wheel axle 8. A brake core 10 is installed on the bottom of the mounting plate 3 by bolts.

[0027] The bottom of the gate core 10 is provided with a circular hole 11 and several screw holes 12. The circular hole 11 is located at the center of the gate core 10, and the screw holes 12 are distributed in a ring array around the circular hole 11.

[0028] like Figure 3 and Figure 7 As shown, a number of inner reinforcing ribs 13 are provided between the inner wall of the mounting plate 3 and the first convex ring 22. Each inner reinforcing rib 13 is connected to the other by annular reinforcing ribs 17, which further increases the strength of the mounting plate 3 and also increases the strength of the brake core 10. The annular reinforcing ribs 17 have reinforcing screw holes 18, which increase the strength of the brake core 10 installed on the mounting plate 3, thereby helping to improve the stability and drivability of the vehicle.

[0029] like Figure 5 As shown, each inner reinforcing rib 13 is divided into a straight section 14, a first reinforcing section 15 and a second reinforcing section 16. The first reinforcing section 15 is attached to the inner wall of the mounting plate 3, and the second reinforcing section 16 is attached to the outer surface of the first convex ring 22. The gate core 10 is placed on the straight section 14.

[0030] The diameter of the circular hole 11 of the gate core 10 is equal to the sum of the diameter of the first convex ring 22 and the width of the second reinforcing section 16.

[0031] like Figure 6 As shown, the back of the mounting plate 3 is provided with a countersunk nut hole 19 corresponding to the reinforcing screw hole 18.

[0032] like Figure 6 As shown, the outer circumferential surface of the second convex ring 23 is provided with several outer reinforcing ribs 20, thereby increasing the strength of the second convex ring 23 and improving the service life and safety performance of the wheel hub.

[0033] The inner wall of the mounting column is provided with several grooves 5 arranged in a ring array, and the grooves 5 located at the edges of the openings at both ends of the mounting column are open grooves.

[0034] like Figure 8 As shown, the front wheel hub insert 6 is a hollow cylinder. Both ends of the front wheel hub insert 6 are provided with mounting grooves 7 for mounting bearings 9. The outer circumferential surface of the front wheel hub insert 6 is provided with protrusions 21 that cooperate with the grooves 5 in the mounting post. The front wheel hub insert 6 is installed in the central hole 4 through the cooperation between the grooves 5 and the protrusions 21, thereby increasing the local and overall rigidity, more effectively distributing the load to the structure, and improving the service life and safety of the wheel hub.

[0035] like Figures 5-7 As shown, hub 1 is a plastic hub, which is lighter than metal or glass, making it easy to transport and carry. It also has high durability and impact resistance, is not easily corroded, has good insulation, strong plasticity, good degradability, and good recyclability. Hub 1 is made by injection molding.
